DETAILED DESCRIPTION OF THE DISCLOSURE

Nucleic acid (e.g., RNAi) therapy is a targeted therapy with high selectivity and specificity. However, in some instances, nucleic acid therapy is also hindered by poor intracellular uptake, limited blood stability and non-specific immune stimulation. To address these issues, various modifications of the nucleic acid composition are explored, such as for example, novel linkers for better stabilizing and/or lower toxicity, optimization of binding moiety for increased target specificity and/or target delivery, and nucleic acid polymer modifications for increased stability and/or reduced off-target effect.


In some embodiments, the arrangement or order of the different components that make-up the nucleic acid composition further effects intracellular uptake, stability, toxicity, efficacy, and/or non-specific immune stimulation. For example, if the nucleic acid component includes a binding moiety, a polymer, and a polynucleic acid molecule (or polynucleotide), the order or arrangement of the binding moiety, the polymer, and/or the polynucleic acid molecule (or polynucleotide) (e.g., binding moiety-polynucleic acid molecule-polymer, binding moiety-polymer-polynucleic acid molecule, or polymer-binding moiety-polynucleic acid molecule) further effects intracellular uptake, stability, toxicity, efficacy, and/or non-specific immune stimulation.


In some embodiments, described herein include a molecule those arrangement of the nucleic acid components effects intracellular uptake, stability, toxicity, efficacy, and/or non-specific immune stimulation. In some instances, the molecule comprises a binding moiety conjugated to a polynucleic acid molecule and a polymer. In some embodiments, the molecule comprises a molecule according to Formula (I): A-X-B-Y-C; in which A is a binding moiety, B is a polynucleotide, C is a polymer, X is a bond or first linker, and Y is a bond or second linker. In some instances, the polynucleotide comprises at least one 2′ modified nucleotide, at least one modified internucleotide linkage, or at least one inverted abasic moiety. In some instances, the molecule of Formula (I) further comprises D, an endosomolytic moiety.

Polynucleic Acid Molecules That Target Androgen Receptor (AR)

Androgen receptor (AR) (also known as NR3C4, nuclear receptor subfamily 3, group C, gene 4) belongs to the steroid hormone group of nuclear receptor superfamily along with related members: estrogen receptor (ER), glucocorticoid receptor (GR), progesterone receptor (PR), and mineralocorticoid receptor (MR). Androgens, or steroid hormones, modulate protein synthesis and tissue remodeling through the androgen receptor. The AR protein is a ligand-inducible zinc finger transcription factor that regulates target gene expression. The presence of mutations in the AR gene has been observed in several types of cancers (e.g., prostate cancer, breast cancer, bladder cancer, or esophageal cancer), and in some instances, has been linked to metastatic progression.


In some embodiments, AR DNA or RNA is wild type or comprises one or more mutations and/or splice variants. In some instances, AR DNA or RNA comprises one or more mutations.

Polynucleic Acid Molecules that Target B-Catenin and B-Catenin-Associated Genes


Catenin beta-1 (also known as CTNNB1, β-catenin, or beta-catenin) is a member of the catenin protein family. In humans, it is encoded by the CTNNB1 gene and is known for its dual functions—cell-cell adhesion and gene transcription. Beta-catenin is an integral structural component of cadherin-based adherens junctions and regulates cell growth and adhesion between cells and anchors the actin cytoskeleton. In some instance, beta-catenin is responsible for transmitting the contact inhibition signal that causes the cells to stop dividing once the epithelial sheet is complete. Beta-catenin is also a key nuclear effector of the Wnt signaling pathway. In some instances, imbalance in the structural and signaling properties of beta-catenin results in diseases and deregulated growth connected to malignancies such as cancer. For example, overexpression of beta-catenin has been linked to cancers such as gastric cancer (Suriano, et al., “Beta-catenin (CTNNB1) gene amplification: a new mechanism of protein overexpression in cancer,” Genes Chromosomes Cancer 42(3): 238-246 (2005)). In some cases, mutations in CTNNB1 gene have been linked to cancer development (e.g., colon cancer, melanoma, hepatocellular carcinoma, ovarian cancer, endometrial cancer, medulloblastoma pilomatricomas, or prostrate cancer), and in some instances, has been linked to metastatic progression. In additional cases, mutations in the CTNNB1 gene cause beta-catenin to translocate to the nucleus without any external stimulus and drive the transcription of its target genes continuously. In some cases, the potential of beta-catenin to change the previously epithelial phenotype of affected cells into an invasive, mesenchyme-like type contributes to metastasis formation.

In some embodiments, an antibody or its binding fragment is further modified using conventional techniques known in the art, for example, by using amino acid deletion, insertion, substitution, addition, and/or by recombination and/or any other modification (e.g. posttranslational and chemical modifications, such as glycosylation and phosphorylation) known in the art either alone or in combination. In some instances, the modification further comprises a modification for modulating interaction with Fc receptors. In some instances, the one or more modifications include those described in, for example, International Publication No. WO97/34631, which discloses amino acid residues involved in the interaction between the Fc domain and the FcRn receptor. Methods for introducing such modifications in the nucleic acid sequence underlying the amino acid sequence of an antibody or its binding fragment is well known to the person skilled in the art.


In some instances, an antibody binding fragment further encompasses its derivatives and includes polypeptide sequences containing at least one CDR.


In some instances, the term “single-chain” as used herein means that the first and second domains of a bi-specific single chain construct are covalently linked, preferably in the form of a co-linear amino acid sequence encodable by a single nucleic acid molecule.


In some instances, a bispecific single chain antibody construct relates to a construct comprising two antibody derived binding domains. In such embodiments, bi-specific single chain antibody construct is tandem bi-scFv or diabody. In some instances, a scFv contains a VH and VL domain connected by a linker peptide. In some instances, linkers are of a length and sequence sufficient to ensure that each of the first and second domains can, independently from one another, retain their differential binding specificities.


In some embodiments, binding to or interacting with as used herein defines a binding/interaction of at least two antigen-interaction-sites with each other. In some instances, antigen-interaction-site defines a motif of a polypeptide that shows the capacity of specific interaction with a specific antigen or a specific group of antigens. In some cases, the binding/interaction is also understood to define a specific recognition. In such cases, specific recognition refers to that the antibody or its binding fragment is capable of specifically interacting with and/or binding to at least two amino acids of each of a target molecule. For example, specific recognition relates to the specificity of the antibody molecule, or to its ability to discriminate between the specific regions of a target molecule. In additional instances, the specific interaction of the antigen-interaction-site with its specific antigen results in an initiation of a signal, e.g. due to the induction of a change of the conformation of the antigen, an oligomerization of the antigen, etc. In further embodiments, the binding is exemplified by the specificity of a “key-lock-principle”. Thus in some instances, specific motifs in the amino acid sequence of the antigen-interaction-site and the antigen bind to each other as a result of their primary, secondary or tertiary structure as well as the result of secondary modifications of said structure. In such cases, the specific interaction of the antigen-interaction-site with its specific antigen results as well in a simple binding of the site to the antigen.


In some instances, specific interaction further refers to a reduced cross-reactivity of the antibody or its binding fragment or a reduced off-target effect. For example, the antibody or its binding fragment that bind to the polypeptide/protein of interest but do not or do not essentially bind to any of the other polypeptides are considered as specific for the polypeptide/protein of interest. Examples for the specific interaction of an antigen-interaction-site with a specific antigen comprise the specificity of a ligand for its receptor, for example, the interaction of an antigenic determinant (epitope) with the antigenic binding site of an antibody.


Additional Binding Moieties

In some embodiments, the binding moiety is a plasma protein. In some instances, the plasma protein comprises albumin. In some instances, the binding moiety A is albumin. In some instances, albumin is conjugated by one or more of a conjugation chemistry described herein to a polynucleic acid molecule. In some instances, albumin is conjugated by native ligation chemistry to a polynucleic acid molecule. In some instances, albumin is conjugated by lysine conjugation to a polynucleic acid molecule.


In some instances, the binding moiety is a steroid. Exemplary steroids include cholesterol, phospholipids, di- and triacylglycerols, fatty acids, hydrocarbons that are saturated, unsaturated, comprise substitutions, or combinations thereof. In some instances, the steroid is cholesterol. In some instances, the binding moiety is cholesterol. In some instances, cholesterol is conjugated by one or more of a conjugation chemistry described herein to a polynucleic acid molecule. In some instances, cholesterol is conjugated by native ligation chemistry to a polynucleic acid molecule. In some instances, cholesterol is conjugated by lysine conjugation to a polynucleic acid molecule.


In some instances, the binding moiety is a polymer, including but not limited to poly nucleic acid molecule aptamers that bind to specific surface markers on cells. In this instance the binding moiety is a polynucleic acid that does not hybridize to a target gene or mRNA, but instead is capable of selectively binding to a cell surface marker similarly to an antibody binding to its specific epitope of a cell surface marker.


In some cases, the binding moiety is a peptide. In some cases, the peptide comprises between about 1 and about 3 kDa. In some cases, the peptide comprises between about 1.2 and about 2.8 kDa, about 1.5 and about 2.5 kDa, or about 1.5 and about 2 kDa. In some instances, the peptide is a bicyclic peptide. In some cases, the bicyclic peptide is a constrained bicyclic peptide. In some instances, the binding moiety is a bicyclic peptide (e.g., bicycles from Bicycle Therapeutics).


In additional cases, the binding moiety is a small molecule. In some instances, the small molecule is an antibody-recruiting small molecule. In some cases, the antibody-recruiting small molecule comprises a target-binding terminus and an antibody-binding terminus, in which the target-binding terminus is capable of recognizing and interacting with a cell surface receptor. For example, in some instances, the target-binding terminus comprising a glutamate urea compound enables interaction with PSMA, thereby, enhances an antibody interaction with a cell (e.g., a cancerous cell) that expresses PSMA. In some instances, a binding moiety is a small molecule described in Zhang et al., “A remote arene-binding site on prostate specific membrane antigen revealed by antibody-recruiting small molecules,” J Am Chem Soc. 132(36): 12711-12716 (2010); or McEnaney, et al., “Antibody-recruiting molecules: an emerging paradigm for engaging immune function in treating human disease,” ACS Chem Biol. 7(7): 1139-1151 (2012).


Production of Antibodies or Binding Fragments Thereof

In some embodiments, polypeptides described herein (e.g., antibodies and its binding fragments) are produced using any method known in the art to be useful for the synthesis of polypeptides (e.g., antibodies), in particular, by chemical synthesis or by recombinant expression, and are preferably produced by recombinant expression techniques.


In some instances, an antibody or its binding fragment thereof is expressed recombinantly, and the nucleic acid encoding the antibody or its binding fragment is assembled from chemically synthesized oligonucleotides (e.g., as described in Kutmeier et al., 1994, BioTechniques 17:242), which involves the synthesis of overlapping oligonucleotides containing portions of the sequence encoding the antibody, annealing and ligation of those oligonucleotides, and then amplification of the ligated oligonucleotides by PCR.


Alternatively, a nucleic acid molecule encoding an antibody is optionally generated from a suitable source (e.g., an antibody cDNA library, or cDNA library generated from any tissue or cells expressing the immunoglobulin) by PCR amplification using synthetic primers hybridizable to the 3′ and 5′ ends of the sequence or by cloning using an oligonucleotide probe specific for the particular gene sequence.


In some instances, an antibody or its binding is optionally generated by immunizing an animal, such as a rabbit, to generate polyclonal antibodies or, more preferably, by generating monoclonal antibodies, e.g., as described by Kohler and Milstein (1975, Nature 256:495-497) or, as described by Kozbor et al. (1983, Immunology Today 4:72) or Cole et al. (1985 in Monoclonal Antibodies and Cancer Therapy, Alan R. Liss, Inc., pp. 77-96). Alternatively, a clone encoding at least the Fab portion of the antibody is optionally obtained by screening Fab expression libraries (e.g., as described in Huse et al., 1989, Science 246:1275-1281) for clones of Fab fragments that bind the specific antigen or by screening antibody libraries (See, e.g., Clackson et al., 1991, Nature 352:624; Hane et al., 1997 Proc. Natl. Acad. Sci. USA 94:4937).


In some embodiments, techniques developed for the production of “chimeric antibodies” (Morrison et al., 1984, Proc. Natl. Acad. Sci. 81:851-855; Neuberger et al., 1984, Nature 312:604-608; Takeda et al., 1985, Nature 314:452-454) by splicing genes from a mouse antibody molecule of appropriate antigen specificity together with genes from a human antibody molecule of appropriate biological activity are used. A chimeric antibody is a molecule in which different portions are derived from different animal species, such as those having a variable region derived from a murine monoclonal antibody and a human immunoglobulin constant region, e.g., humanized antibodies.


In some embodiments, techniques described for the production of single chain antibodies (U.S. Pat. No. 4,694,778; Bird, 1988, Science 242:423-42; Huston et al., 1988, Proc. Natl. Acad. Sci. USA 85:5879-5883; and Ward et al., 1989, Nature 334:544-54) are adapted to produce single chain antibodies. Single chain antibodies are formed by linking the heavy and light chain fragments of the Fv region via an amino acid bridge, resulting in a single chain polypeptide. Techniques for the assembly of functional Fv fragments in E. coli are also optionally used (Skerra et al., 1988, Science 242:1038-1041).


In some embodiments, an expression vector comprising the nucleotide sequence of an antibody or the nucleotide sequence of an antibody is transferred to a host cell by conventional techniques (e.g., electroporation, liposomal transfection, and calcium phosphate precipitation), and the transfected cells are then cultured by conventional techniques to produce the antibody. In specific embodiments, the expression of the antibody is regulated by a constitutive, an inducible or a tissue, specific promoter.


In some embodiments, a variety of host-expression vector systems is utilized to express an antibody or its binding fragment described herein. Such host-expression systems represent vehicles by which the coding sequences of the antibody is produced and subsequently purified, but also represent cells that are, when transformed or transfected with the appropriate nucleotide coding sequences, express an antibody or its binding fragment in situ. These include, but are not limited to, microorganisms such as bacteria (e.g., E. coli and B. subtilis) transformed with recombinant bacteriophage DNA, plasmid DNA or cosmid DNA expression vectors containing an antibody or its binding fragment coding sequences; yeast (e.g., Saccharomyces Pichia) transformed with recombinant yeast expression vectors containing an antibody or its binding fragment coding sequences; insect cell systems infected with recombinant virus expression vectors (e.g., baculovirus) containing an antibody or its binding fragment coding sequences; plant cell systems infected with recombinant virus expression vectors (e.g., cauliflower mosaic virus (CaMV) and tobacco mosaic virus (TMV)) or transformed with recombinant plasmid expression vectors (e.g., Ti plasmid) containing an antibody or its binding fragment coding sequences; or mammalian cell systems (e.g., COS, CHO, BH, 293, 293T, 3T3 cells) harboring recombinant expression constructs containing promoters derived from the genome of mammalian cells (e.g., metallothionein promoter) or from mammalian viruses (e.g. the adenovirus late promoter; the vaccinia virus 7.5K promoter).


For long-term, high-yield production of recombinant proteins, stable expression is preferred. In some instances, cell lines that stably express an antibody are optionally engineered. Rather than using expression vectors that contain viral origins of replication, host cells are transformed with DNA controlled by appropriate expression control elements (e.g., promoter, enhancer, sequences, transcription terminators, polyadenylation sites, etc.), and a selectable marker. Following the introduction of the foreign DNA, engineered cells are then allowed to grow for 1-2 days in an enriched media, and then are switched to a selective media. The selectable marker in the recombinant plasmid confers resistance to the selection and allows cells to stably integrate the plasmid into their chromosomes and grow to form foci that in turn are cloned and expanded into cell lines. This method can advantageously be used to engineer cell lines which express the antibody or its binding fragments.


In some instances, a number of selection systems are used, including but not limited to the herpes simplex virus thymidine kinase (Wigler et al., 1977, Cell 11:223), hypoxanthine-guanine phosphoribosyltransferase (Szybalska & Szybalski, 192, Proc. Natl. Acad. Sci. USA 48:202), and adenine phosphoribosyltransferase (Lowy et al., 1980, Cell 22:817) genes are employed in tk-, hgprt- or aprt-cells, respectively. Also, antimetabolite resistance are used as the basis of selection for the following genes: dhfr, which confers resistance to methotrexate (Wigler et al., 1980, Proc. Natl. Acad. Sci. USA 77:357; O'Hare et al., 1981, Proc. Natl. Acad. Sci. USA 78:1527); gpt, which confers resistance to mycophenolic acid (Mulligan & Berg, 1981, Proc. Natl. Acad. Sci. USA 78:2072); neo, which confers resistance to the aminoglycoside G-418 (Clinical Pharmacy 12:488-505; Wu and Wu, 1991, Biotherapy 3:87-95; Tolstoshev, 1993, Ann. Rev. Pharmacol. Toxicol. 32:573-596; Mulligan, 1993, Science 260:926-932; and Morgan and Anderson, 1993, Ann. Rev. Biochem. 62:191-217; May, 1993, TIB TECH 11(5):155-215) and hygro, which confers resistance to hygromycin (Santerre et al., 1984, Gene 30:147). Methods commonly known in the art of recombinant DNA technology which can be used are described in Ausubel et al. (eds., 1993, Current Protocols in Molecular Biology, John Wiley & Sons, NY; Kriegler, 1990, Gene Transfer and Expression, A Laboratory Manual, Stockton Press, NY; and in Chapters 12 and 13, Dracopoli et al. (eds), 1994, Current Protocols in Human Genetics, John Wiley & Sons, NY.; Colberre-Garapin et al., 1981, J. Mol. Biol. 150:1).


In some instances, the expression levels of an antibody are increased by vector amplification (for a review, see Bebbington and Hentschel, The use of vectors based on gene amplification for the expression of cloned genes in mammalian cells in DNA cloning, Vol. 3. (Academic Press, New York, 1987)). When a marker in the vector system expressing an antibody is amplifiable, an increase in the level of inhibitor present in culture of host cell will increase the number of copies of the marker gene. Since the amplified region is associated with the nucleotide sequence of the antibody, production of the antibody will also increase (Crouse et al., 1983, Mol. Cell Biol. 3:257).


In some instances, any method known in the art for purification of an antibody is used, for example, by chromatography (e.g., ion exchange, affinity, particularly by affinity for the specific antigen after Protein A, and sizing column chromatography), centrifugation, differential solubility, or by any other standard technique for the purification of proteins.

Therapeutic Regimens

In some embodiments, the pharmaceutical compositions described herein are administered for therapeutic applications. In some embodiments, the pharmaceutical composition is administered once per day, twice per day, three times per day or more. The pharmaceutical composition is administered daily, every day, every alternate day, five days a week, once a week, every other week, two weeks per month, three weeks per month, once a month, twice a month, three times per month, or more. The pharmaceutical composition is administered for at least 1 month, 2 months, 3 months, 4 months, 5 months, 6 months, 7 months, 8 months, 9 months, 10 months, 11 months, 12 months, 18 months, 2 years, 3 years, or more.


In some embodiments, one or more pharmaceutical compositions are administered simultaneously, sequentially, or at an interval period of time. In some embodiments, one or more pharmaceutical compositions are administered simultaneously. In some cases, one or more pharmaceutical compositions are administered sequentially. In additional cases, one or more pharmaceutical compositions are administered at an interval period of time (e.g., the first administration of a first pharmaceutical composition is on day one followed by an interval of at least 1, 2, 3, 4, 5, or more days prior to the administration of at least a second pharmaceutical composition).


In some embodiments, two or more different pharmaceutical compositions are coadministered. In some instances, the two or more different pharmaceutical compositions are coadministered simultaneously. In some cases, the two or more different pharmaceutical compositions are coadministered sequentially without a gap of time between administrations. In other cases, the two or more different pharmaceutical compositions are coadministered sequentially with a gap of about 0.5 hour, 1 hour, 2 hour, 3 hour, 12 hours, 1 day, 2 days, or more between administrations.


In the case wherein the patient's status does improve, upon the doctor's discretion the administration of the composition is given continuously; alternatively, the dose of the composition being administered is temporarily reduced or temporarily suspended for a certain length of time (i.e., a “drug holiday”). In some instances, the length of the drug holiday varies between 2 days and 1 year, including by way of example only, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 10 days, 12 days, 15 days, 20 days, 28 days, 35 days, 50 days, 70 days, 100 days, 120 days, 150 days, 180 days, 200 days, 250 days, 280 days, 300 days, 320 days, 350 days, or 365 days. The dose reduction during a drug holiday is from 10%-100%, including, by way of example only, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or 100%.


Once improvement of the patient's conditions has occurred, a maintenance dose is administered if necessary. Subsequently, the dosage or the frequency of administration, or both, are optionally reduced, as a function of the symptoms, to a level at which the improved disease, disorder or condition is retained.


In some embodiments, the amount of a given agent that correspond to such an amount varies depending upon factors such as the particular compound, the severity of the disease, the identity (e.g., weight) of the subject or host in need of treatment, but nevertheless is routinely determined in a manner known in the art according to the particular circumstances surrounding the case, including, e.g., the specific agent being administered, the route of administration, and the subject or host being treated. In some instances, the desired dose is conveniently presented in a single dose or as divided doses administered simultaneously (or over a short period of time) or at appropriate intervals, for example as two, three, four or more sub-doses per day.


The foregoing ranges are merely suggestive, as the number of variables in regard to an individual treatment regime is large, and considerable excursions from these recommended values are not uncommon. Such dosages are altered depending on a number of variables, not limited to the activity of the compound used, the disease or condition to be treated, the mode of administration, the requirements of the individual subject, the severity of the disease or condition being treated, and the judgment of the practitioner.


In some embodiments, toxicity and therapeutic efficacy of such therapeutic regimens are determined by standard pharmaceutical procedures in cell cultures or experimental animals, including, but not limited to, the determination of the LD50 (the dose lethal to 50% of the population) and the ED50 (the dose therapeutically effective in 50% of the population). The dose ratio between the toxic and therapeutic effects is the therapeutic index and it is expressed as the ratio between LD50 and ED50. Compounds exhibiting high therapeutic indices are preferred. The data obtained from cell culture assays and animal studies are used in formulating a range of dosage for use in human. The dosage of such compounds lies preferably within a range of circulating concentrations that include the ED50 with minimal toxicity. The dosage varies within this range depending upon the dosage form employed and the route of administration utilized.

Example 2. General Experimental Protocol

Stem-Loop qPCR Assay for Quantification of siRNA


Plasma samples were directly diluted in TE buffer. 50 mg tissue pieces were homogenized in 1 mL of Trizol using a FastPrep-24 tissue homogenizer (MP Biomedicals) and then diluted in TE buffer. Standard curves were generated by spiking siRNA into plasma or homogenized tissue from untreated animals and then serially diluting with TE buffer. The antisense strand of the siRNA was reverse transcribed using a TaqMan MicroRNA reverse transcription kit (Applied Biosy stems) with 25 nM of a sequence-specific stem-loop RT primer. The cDNA from the RT step was utilized for real-time PCR using TaqMan Fast Advanced Master Mix (Applied Biosy stems) with 1.5 μM of forward primer, 0.75 μM of reverse primer, and 0.2 μM of probe. The sequences of KRAS and EGFR siRNA antisense strands and all primers and probes used to measure them are shown in Table 13. Quantitative PCR reactions were performed using standard cycling conditions in a ViiA 7 Real-Time PCR System (Life Technologies). The Ct values were transformed into plasma or tissue concentrations using the linear equations derived from the standard curves.

Comparative qPCR Assay for Determination of mRNA Knockdown


Tissue samples were homogenized in Trizol as described above. Total RNA was isolated using RNeasy RNA isolation 96-well plates (Qiagen), then 500 ng RNA was reverse transcribed with a High Capacity RNA to cDNA kit (ThermoFisher). KRAS, EGFR, CTNNB1 and PPIB mRNA was quantified by TaqMan qPCR analysis performed with a ViiA 7 Real-Time PCR System. The TaqMan primers and probes for KRAS were designed and validated by Avidity and are shown in Table 14. The TaqMan primers and probes for EGFR and CTNNB1 were purchased from Applied Biosystems as pre-validated gene expression assays. PPIB (housekeeping gene) was used as an internal RNA loading control, with all TaqMan primers and probes for PPIB purchased from Applied Biosystems as pre-validated gene expression assays. Results are calculated by the comparative Ct method, where the difference between the target gene (KRAS, CTNNB1, or EGFR) Ct value and the PPIB Ct value (ΔCt) is calculated and then further normalized relative to the PBS control group by taking a second difference (ΔΔCt).

Animals


All animal studies were conducted following protocols in accordance with the Institutional Animal Care and Use Committee (IACUC) at Explora BioLabs, which adhere to the regulations outlined in the USDA Animal Welfare Act as well as the “Guide for the Care and Use of Laboratory Animals” (National Research Council publication, 8th Ed., revised in 2011). All mice were obtained from either Charles River Laboratories or Harlan Laboratories.


H358, HCC827, and Hep-3B2 1-7 Subcutaneous Flank Tumor Model


For the H358 subcutaneous flank tumor model, tumor cells were inoculated and tumors were established according to the following methods. Female NCr nu/nu mice were identified by ear-tag the day before cell injection. Mice were weighed prior to inoculation. H358 cells were cultured with 10% FBS/RPMI medium and harvested with 0.05% Trypsin and Cell Stripper (MediaTech) 5 million H358 cells in 0.05 ml Hank's Balanced Salt Solution (HBSS) with Matrigel (1:1) were injected subcutaneously (SC) into the upper right flank of each mouse. Tumor growth was monitored by tumor volume measurement using a digital caliper starting on day 7 after inoculation, and followed 2 times per week until average tumor volume reaches >100 & ≤300 mm3. Once tumors were staged to the desired volume (average from 100 to 300 mm3), animals were randomized and mice with very large or small tumors were culled. Mice were divided into the required groups and randomized by tumor volume. Mice were then treated as described in the individual experiments.


For the Hep3B orthotropic liver tumor model, tumor cells were inoculated and tumors were established according to the following methods. Female NCr nu/nu mice were identified by ear-tag the day before, mice will be anesthetized with isoflurane. The mice were then placed in a supine position on a water circulating heating pad to maintain body temperature. A small transverse incision below the sternum will be made to expose the liver. Cancer cells were slowly injected into the upper left lobe of the liver using a 28-gauge needle. The cells were injected at a 30-degree angle into the liver, so that a transparent bleb of cells can be seen through the liver capsule. Hep 3B2.1 7 cells were prepared by suspending in cold PBS (0.1-5×106 cells) and mixing with diluted matrigel (30× in PBS). 30-50 ul of the cell/matrigel was inoculated. After injection, a small piece of sterile gauze was placed on the injection site, and light pressure was applied for 1 min to prevent bleeding. The abdomen was then closed with a 6-0 silk suture. After tumor cell implantation, animals were kept in a warm cage, observed for 1-2 h, and subsequently returned to the animal room after full recovery from the anesthesia. 7-10 days after tumor implantation animals were randomized, divided into the required groups and then treated as described in the individual experiments.


LNCap Subcutaneous Flank Tumor Model


LNCaP cells (ATCC® CRL-1740™) were grown in RPMI+10% FBS supplemented with non-essential amino acids and sodium pyruvate to a confluency of about 80%. Cells were mixed 1:1 with matrigel and 5-7*106 cells injected subcutaneously into male SCID mice (6-8 weeks). Tumors usually developed within 3-5 weeks to a size of 100-350 mm3. Animals bearing tumors within this range were randomized and treated with ASCs by injections into the tail vein. For PD studies animals were sacrificed 96 hours after injection and organ fragments harvested, weighted, and frozen in liquid nitrogen. For RNA isolation, organ samples were homogenized in Trizol and RNA prepared using a Qiagen RNeasy 96 Plus kit following the instructions by the manufacturer. RNA concentrations were determined spectroscopically. RNAs were converted into cDNAs by reverse transcription and expression of specific targets quantified by qPCR using the ΔΔCT method and validated Taqman assays (Thermofisher). Samples were standardize to the expression levels of PPIB.


Cholesterol siRNA Conjugate Synthesis


All siRNA single strands were fully assembled on solid phase using standard phosphoramidite chemistry and purified over HPLC. Purified single strands were duplexed to get the double stranded siRNA. Structure of cholesterol conjugated to the passenger strand is illustrated in FIG. 2. Table 15 shows KRAS, EGFR, and CTNNB1 siRNA sequences.

Peptide Synthesis


Peptides were synthesized on solid phase using standard Fmoc chemistry. Both peptides have cysteine at the N-terminus and the cleaved peptides were purified by HPLC and confirmed by mass spectroscopy. INF7 peptide is as illustrated in FIG. 3 (SEQ ID NO: 2055). Melittin peptide is as illustrated in FIG. 4 (SEQ ID NO: 2060).


Anti-EGFR Antibody


Anti-EGFR antibody is a fully human IgG1κ monoclonal antibody directed against the human epidermal growth factor receptor (EGFR). It is produced in the Chinese Hamster Ovary cell line DJT33, which has been derived from the CHO cell line CHO-K1SV by transfection with a GS vector carrying the antibody genes derived from a human anti-EGFR antibody producing hybridoma cell line (2F8). Standard mammalian cell culture and purification technologies are employed in the manufacturing of anti-EGFR antibody.


The theoretical molecular weight (MW) of anti-EGFR antibody without glycans is 146.6 kDa. The experimental MW of the major glycosylated isoform of the antibody is 149 kDa as determined by mass spectrometry. Using SDS-PAGE under reducing conditions the MW of the light chain was found to be approximately 25 kDa and the MW of the heavy chain to be approximately 50 kDa. The heavy chains are connected to each other by two inter-chain disulfide bonds, and one light chain is attached to each heavy chain by a single inter-chain disulfide bond. The light chain has two intra-chain disulfide bonds and the heavy chain has four intra-chain disulfide bonds. The antibody is N-linked glycosylated at Asn305 of the heavy chain with glycans composed of N-acetyl-glucosamine, mannose, fucose and galactose. The predominant glycans present are fucosylated bi-antennary structures containing zero or one terminal galactose residue.


The charged isoform pattern of the IgG1κ antibody has been investigated using imaged capillary IEF, agarose IEF and analytical cation exchange HPLC. Multiple charged isoforms are found, with the main isoform having an isoelectric point of approximately 8.7.


The major mechanism of action of anti-EGFR antibody is a concentration dependent inhibition of EGF-induced EGFR phosphorylation in A431 cancer cells. Additionally, induction of antibody-dependent cell-mediated cytotoxicity (ADCC) at low antibody concentrations has been observed in pre-clinical cellular in vitro studies.


Example 3: Synthesis, Purification and Analysis of Antibody-PEG-EGFR and Antibody-EGFR Conjugates




Step 1: Antibody Conjugation with Maleimide-PEG-NHS Followed by SH-EGFR


Anti-EGFR antibody (EGFR-Ab) was exchanged with 1× Phosphate buffer (pH 7.4) and made up to 5 mg/ml concentration. To this solution, 2 equivalents of SMCC linker or maleimide-PEGxkDa-NHS (x=1, 5, 10, 20) was added and rotated for 4 hours at room temperature. Unreacted maleimide-PEG was removed by spin filtration using 50 kDa MWCO Amicon spin filters and PBS pH 7.4. The antibody-PEG-Mal conjugate was collected and transferred into a reaction vessel. SH-C6-EGFR (2 equivalents) was added at RT to the antibody-PEG-maleimide in PBS and rotated overnight. The reaction mixture was analyzed by analytical SAX column chromatography and conjugate along with unreacted antibody and siRNA was seen.


Step 2: Purification


The crude reaction mixture was purified by AKTA explorer FPLC using anion exchange chromatography method-1. Fractions containing the antibody-PEG-EGFR conjugate were pooled, concentrated and buffer exchanged with PBS, pH 7.4. Antibody siRNA conjugates with SMCC linker, PEG1 kDa, PEG5 kDa and PEG10 kDa were separated based on the siRNA loading. Conjugates with PEG20 kDa gave poor separation.


Step-3: Analysis of the Purified Conjugate


The isolated conjugate was characterized by either mass spec or SDS-PAGE. The purity of the conjugate was assessed by analytical HPLC using either anion exchange chromatography method-2 or anion exchange chromatography method-3. Examples of all the conjugates made using these methods are described in Table 16.

Step 1: Antibody Conjugation with SMCC Linker or Maleimide-PEG-NHS Followed by SH-Cys-Peptide-CONH2


Anti-EGFR antibody was exchanged with 1× Phosphate buffer (pH 7.4) and made up to 10 mg/ml concentration. To this solution, 3 equivalents of SMCC linker (succinimidyl 4-(N-maleimidomethyl)cyclohexane-1-carboxylate) or maleimide-PEG1 kDa-NHS was added and rotated for 1.5 hours at room temperature. Unreacted SMCC linker or PEG linker was removed by spin filtration using 50 kDa MWCO Amicon spin filters and PBS buffer pH 7.4 (25 mM MES pH=6.1 for Melittin conjugates). The retentate was collected and 3 equivalents of SH-Cys-Peptide-CONH2 was added at RT and rotated overnight.

Example 7: Synthesis, Purification and Analysis of EEP-Antibody-siRNA-PEG Conjugates




Step 1: Conjugation of PEG24 linker followed by SH-Cys-Peptide-CONH2 to EGFR-Ab-siRNA-PEG


EGFR-Ab-siRNA-PEG conjugate with a siRNA loading of 1 was conjugated with 4 equivalents of PEG1k linker (succinimidyl 4-(N-maleimidomethyl)cyclohexane-1-carboxylate) in PBS, pH 7.4 buffer and rotated for 1.5 hours at room temperature. Unreacted PEG1k linker was removed by spin filtration using 50 kDa MWCO Amicon spin filters and PBS buffer pH 7.4. The retentate was collected and 4 equivalents of SH-Cys-Peptide-CONH2 was added at RT and rotated overnight.


Step 2: Purification


The reaction mixture was then purified by repeated spin filtration using PBS buffer pH7.4 and 50 kDa Amicon spin filters until the unreacted peptide was removed as monitored by HPLC. The product contains a mixture of conjugates with 0, 1, 2, 3 or more peptides conjugated to the antibody backbone.


Step-3: Analysis of the Purified Conjugate


The isolated conjugate was characterized by either mass spec or SDS-PAGE. The purity and the peptide loading of the conjugate was assessed by analytical HPLC using either HIC method-2 or cation exchange chromatography method-2. Examples of the conjugates made using the method described in Example 7 are shown in Table 20.

Example 8: In Vivo Pharmacokinetics Study of a EGFR Antibody-siRNA-PEG Conjugate (PK-055)

Groups (n=3) of female NCr nu/nu mice bearing subcutaneous flank H358 tumors 100-150 mm3 in volume were treated with one intravenous (i.v.) tail vein injection of siRNA conjugate, while control groups (n=4) of the same mice received one i.v. injection of PBS as a vehicle control. Treatment groups that received EGFR antibody-siRNA-PEG conjugates were dosed at 0.5 mg/kg (based on the weight of siRNA) and groups that received cholesterol-siRNA conjugates were dosed at 15 mg/kg. All groups (treatments and controls) were administered a dose volume of 5 mL/kg. Non-terminal blood samples were collected at 2, 15, or 60 minutes post-dose via puncture of the retro-orbital plexus and centrifuged to generate plasma for PK analysis. Mice were sacrificed by CO2 asphyxiation at 24, 96, or 168 h post-dose. Table 21 describes the study design in more detail and provides a cross-reference to the conjugate synthesis and characterization. Terminal blood samples were collected via cardiac puncture and processed to generate plasma for PK analysis. 50 mg pieces of tumor, liver, kidney, and lung were collected and snap-frozen in liquid nitrogen. mRNA knockdown analysis and siRNA quantitation were performed as described in Examples 2-7.

PEG linkers of various molecular weights and a small molecule linker were used to attach EGFR siRNA to an EGFR antibody (EGFR-Ab) and the PK was assessed to determine the effect of the linker molecular weight on the behavior of the mAb-siRNA conjugate in plasma. As illustrated in FIG. 21, the molecular weight of the PEG linker does not have a large impact on the plasma PK, except for the 10 kDa PEG leads to a faster siRNA clearance (i.e. lower plasma concentrations at later times). The orientation of the siRNA and PEG relative to the EGFR-Ab was also explored. As illustrated in FIG. 22, having the siRNA in between the EGFR-Ab and the PEG5k (EGFR antibody-KRAS-PEG5k) results in significantly higher plasma concentrations than the alternative conjugate where PEG5k is in between the EGFR-Ab and the siRNA (EGFR antibody-PEG5k-EGFR). In some instances, the use of two different siRNAs on these conjugates does not impact the plasma kinetics.


The drug loading on the EGFR-Ab was also investigated, with n=1 and n=2 siRNAs per EGFR-Ab. As illustrated in FIG. 23, having only one siRNA per EGFR-Ab resulted in much higher plasma concentrations, whereas the higher loading of n=2 siRNA per EGFR-Ab resulted in faster clearance from plasma. The impact of adding an endosomal escape peptide (melittin) was assessed. EGFR antibody-KRAS-PEG5k and EGFR antibody-melittin were mixed together in solution and co-injected. As illustrated in FIG. 24, the presence of EGFR antibody-melittin increases the clearance from plasma of EGFR antibody-KRAS-PEG5k at later times.


The plasma PK of cholesterol-siRNA conjugates was next compared to the mAb-siRNA conjugates after intravenous administration via tail vein injection. As illustrated in FIG. 25, the chol-siRNA conjugates are cleared much faster from plasma than the mAb-siRNA conjugates. As illustrated from the PK profile, having either EGFR or KRAS siRNA on the conjugate did not affect the plasma kinetics.


In addition to the plasma PK analysis, siRNA concentrations were determined in tissues at various times post-dose to determine the tissue PK. Tissue concentrations were measured pmol/g and then converted to pmol/mL by assuming the density of tissue equals 1 g/mL. In FIG. 26, a concentration of 1 nM=1 nmol/L=1 pmol/mL=1 pmol/g tissue. As illustrated in FIG. 26A, a single i.v. dose of 0.5 mg/kg of EGFR antibody-siRNA resulted in approximately 100 nM concentrations of siRNA in tumor at 24 h post-dose for virtually all of the conjugates. In the case of these EGFR antibody-linker-siRNA conjugates, the molecular weight of the linker between the EGFR-Ab and the EGFR siRNA does not seem to alter the PK of these conjugates in the s.c. flank H358 tumors. As illustrated in FIG. 26B, the concentration of siRNA in liver following a single i.v. dose of 0.5 mg/kg of EGFR antibody-siRNA is approximately 100 nM at 24 h post-dose, similar to that seen in tumor. Only the small molecule linker at 24 h post-dose produces a siRNA concentration in liver approximately half of what is seen with longer PEG linkers. siRNA concentrations decrease over time in both tumor and liver tissue with these EGFR antibody-linker-siRNA conjugates.


The orientation of the siRNA and PEG relative to the EGFR-Ab was also explored relative to the tissue PK profiles. As illustrated in FIG. 27, both the EGFR antibody-KRAS-PEG5k and the EGFR antibody-PEG5k-EGFR conjugates deliver approximately 100 nM siRNA into both tumor and liver following a single i.v. dose of 0.5 mg/kg. However, while the EGFR antibody-KRAS-PEG5k maintains the siRNA concentration in tumor at approximately 100 nM until 168 h post-dose, the other 3 curves decline in concentration over time. Next, the tissue PK as a function of drug loading was assessed. As illustrated from FIG. 28, n=1 siRNA per EGFR-Ab delivered higher amounts of siRNA into tumor compared to liver. However, increasing the siRNA loading to n=2 siRNA per EGFR-Ab increased the amount of siRNA delivered to liver and decreased the amount of siRNA delivered to tumor. Additionally, EGFR antibody-melittin was mixed with some formulations in order to introduce endosomal escape functionality. As illustrated from FIG. 29, mixing and co-administering EGFR antibody-melittin with EGFR antibody-siRNA did not have a large impact on the tissue PK. The addition of melittin decreased uptake of siRNA in tumor and increased the uptake of siRNA in liver.


The tissue PK profiles of cholesterol-siRNA conjugates (using both EGFR and KRAS siRNA) in liver and in s.c. flank H358 tumors was also assessed. As illustrated from FIG. 30, both chol-siRNA conjugates delivered approximately 5 μM concentrations of siRNA into liver 24 h following a single i.v. dose of 15 mg/kg. In liver, the chol-KRAS appears to clear slightly faster than the chol-EGFR on the 1-week time scale. The two different chol-siRNA conjugates further show different PK profiles in tumor. Both cholesterol conjugates deliver less siRNA into tumor compared to liver, but the chol-EGFR delivers more siRNA into tumor when compared to the chol-KRAS conjugate. Both chol-siRNA conjugates are cleared from tumor over time and with a similar slope.


A PD analysis followed the PK analysis. As illustrated in FIG. 31A, the chol-KRAS conjugate produced only marginal (˜25%) mRNA knockdown of the KRAS target gene in tumor following a single i.v. dose of 15 mg/kg. However, as illustrated in FIG. 31B, the same 15 mg/kg dose of chol-KRAS was able to produce >50% mRNA knockdown in the mouse liver. The chol-EGFR conjugate was able to produce >50% mRNA knockdown in tumor, as illustrated in FIG. 32. In some instances, the higher knockdown with chol-EGFR in tumor compared to chol-KRAS is due to the higher siRNA concentrations observed in tumor with chol-EGFR compared to chol-KRAS (FIG. 30). Finally, as illustrated in FIGS. 33 and 34, most of the EGFR antibody-siRNA conjugates resulted in approximately 25-50% EGFR or KRAS mRNA knockdown in tumors after a single IV dose, but at a much lower dose (0.5 mg/kg) compared to the chol-siRNA conjugates.

siRNA Synthesis


All siRNA single strands were fully assembled on solid phase using standard phosphoramidite chemistry and purified over HPLC. Purified single strands were duplexed to get the double stranded siRNA.


Each siRNA passenger strand contains two conjugation handles, C6-NH2 and C6-SH, one at each end of the strand. The passenger strand with C6-NH2 handle at 5′ end contains C6-SH at its 3′ end and the strand that contains C6-NH2 handle at 3′ end contains C6-SH at its 5′ end. Both conjugation handles are connected to siRNA passenger strand via inverted abasic phosphodiester or phosphorothioate.

Zalutumumab (EGFR-Ab)


Zalutumumab is a fully human IgG1κ monoclonal antibody directed against the human epidermal growth factor receptor (EGFR). It is produced in the Chinese Hamster Ovary cell line DJT33, which has been derived from the CHO cell line CHO-K1SV by transfection with a GS vector carrying the antibody genes derived from a human anti-EGFR antibody producing hybridoma cell line (2F8). Standard mammalian cell culture and purification technologies are employed in the manufacturing of zalutumumab.


The theoretical molecular weight (MW) of zalutumumab without glycans is 146.6 kDa. The experimental MW of the major glycosylated isoform of the antibody is 149 kDa as determined by mass spectrometry. Using SDS-PAGE under reducing conditions the MW of the light chain was found to be approximately 25 kDa and the MW of the heavy chain to be approximately 50 kDa. The heavy chains are connected to each other by two inter-chain disulfide bonds, and one light chain is attached to each heavy chain by a single inter-chain disulfide bond. The light chain has two intra-chain disulfide bonds and the heavy chain has four intra-chain disulfide bonds. The antibody is N-linked glycosylated at Asn305 of the heavy chain with glycans composed of N-acetyl-glucosamine, mannose, fucose and galactose. The predominant glycans present are fucosylated bi-antennary structures containing zero or one terminal galactose residue. The charged isoform pattern of the IgG1κ antibody has been investigated using imaged capillary IEF, agarose IEF and analytical cation exchange HPLC. Multiple charged isoforms are found, with the main isoform having an isoelectric point of approximately 8.7.


The major mechanism of action of zalutumumab is a concentration dependent inhibition of EGF-induced EGFR phosphorylation in A431 cancer cells. Additionally, induction of antibody-dependent cell-mediated cytotoxicity (ADCC) at low antibody concentrations has been observed in pre-clinical cellular in vitro studies.


Panitumumab (EGFR2-Ab)


Panitumumab is a clinically approved, fully human IgG2 subclass monoclonal antibody specific to the epidermal growth factor receptor (EGFR) Panitumumab has two gamma heavy chains and two kappa light chains. Glycosylated panitumumab has a total molecular weight of approximately 147 kDa. Panitumumab is expressed as a glycoprotein with a single consensus N-linked glycosylation site located on the heavy chain Panitumumab is produced from Chinese Hamster Ovary (CHO) cells and purified by a series of chromatography steps, viral inactivation step, viral filtration step and ultrafiltration/diafiltration steps.


Panitumumab acts as a competitive antagonist at the ligand binding site of EGFR to inhibit binding and signaling mediated by EGF and transforming growth factor α, the natural ligands for this receptor. The affinity of binding panitumumab to the EGFR was determined be 3.5 and 5.7×10−12M in recombinant EGFR using BIAcore methods. Inhibition of binding of EGF was shown in A431 cells, a human epidermal carcinoma cell line that expresses EGFR. Intracellular acidification, phosphorylation and internalization of the EGFR were blocked in a dose-dependent manner by panitumumab in A431 cells. Panitumumab was also shown to inhibit cell growth in vitro and in vivo in the same cell line.


Herceptin (EGFR3-Ab)


Herceptin is a clinically approved, humanized IgG1 subclass monoclonal antibody specific to the epidermal growth factor receptor2 (EGFR2) also known as Her2. Herceptin has human Fc yl isotype along with kappa light chains.


PSMA-Ab

siRNA Design and Synthesis


EFGR: A 21mer duplex with 19 bases of complementarity and 3′ dinucleotide overhangs was designed against human EGFR. The sequence of the guide/antisense strand was complementary to the gene sequence starting a base position 333 for the human mRNA transcript for EGFR (ACUCGUGCCUUGGCAAACUUU; SEQ ID NO: 2082). Base, sugar and phosphate modifications were used to optimize the potency of the duplex and reduce immunogenicity. All siRNA single strands were fully assembled on solid phase using standard phosphoramidite chemistry and purified over HPLC. Purified single strands were duplexed to obtain the double stranded siRNA. The passenger strand contained two conjugation handles, a C6-NH2 at the 5′ end and a C6-SH at the 3′ end. Both conjugation handles were connected to siRNA passenger strand via phosphorothioate-inverted abasic-phosphorothioate linker, see Example 9 for the chemical structure.

In Vivo Study Design


Groups (n=5) of female SCID SHO mice bearing subcutaneous flank LNCaP tumors 100-350 mm3 in volume were treated with one intravenous (i.v.) tail vein injection of siRNA conjugate, while control groups (n=5) of the same mice received one i.v. injection of PBS as a vehicle control. Treatment groups 1-6 were dosed at 1.0 or 0.5 mg/kg (based on the weight of siRNA) as per the study design below. All groups (treatments and controls) were administered a dose volume of 5 mL/kg. Mice were sacrificed by CO2 asphyxiation at 96 hours post-dose. Table 22 describes the study design in more detail. 50 mg pieces of tumor and liver, were collected and snap-frozen in liquid nitrogen. mRNA knockdown in target tissue was determined using a comparative qPCR assay as described in Example 2. Total RNA was extracted from the tissue, reverse transcribed and mRNA levels were quantified using TaqMan qPCR, using the appropriately designed primers and probes. PPIB (housekeeping gene) was used as an internal RNA loading control, results were calculated by the comparative Ct method, where the difference between the target gene Ct value and the PPIB Ct value (ΔCt) is calculated and then further normalized relative to the PBS control group by taking a second difference (ΔΔCt). Quantitation of tissue siRNA concentrations were determined using a stem-loop qPCR assay as described in Example 2. The antisense strand of the siRNA was reverse transcribed using a TaqMan MicroRNA reverse transcription kit using a sequence-specific stem-loop RT primer. The cDNA from the RT step was then utilized for real-time PCR and Ct values were transformed into plasma or tissue concentrations using the linear equations derived from the standard curves.

The orientation of the siRNA and PEG relative to the PSMA-Ab was explored in an in vivo mouse tumor model. As illustrated in FIG. 50A, having the siRNA in between the PSMA-Ab and the PEG5k (PSMA-Ab(Cys)-EGFR-PEG5k or the AXBYC format) resulted in higher levels of EGFR mRNA knockdown in the tumor relative to the alternative conjugate where PEG5k is in between the PSMA-Ab and the siRNA (PSMA-Ab(Cys)-PEG5k-EGFR or AXCYB format). This approach (AXBYC) also resulted in higher levels of EGFR mRNA knockdown in the tumor relative to the conjugate without PEG5K (PSMA-Ab(Cys)-EGFR or AXB format).


The orientation of the siRNA and PEG relative to the PSMA-Ab was also explored relative to the tissue PK profiles. Tissue concentrations were measured pmol/g and then converted to pmol/mL by assuming the density of tissue equals 1 g/mL (a concentration of 1 nM=1 nmol/L=1 pmol/mL=1 pmol/g tissue). As illustrated in FIG. 50B, having the siRNA in between the PSMA-Ab and the PEG5k (AXBYC) resulted in higher levels of siRNA delivery to the tumor relative to the alternative conjugate where PEG5k is in between the PSMA-Ab and the siRNA (AXCYB). This approach (AXBYC) resulted in higher levels of EGFR siRNA delivery to the tumor relative to the conjugate without PEG5K (AXB).


In a mouse LNCaP subcutaneous xenograph model, it was demonstrated that the AXBYC format for the antibody siRNA conjugate resulted in higher levels of siRNA accumulation in the tumor tissue and a greater magnitude of EGFR mRNA knockdown, relative to the AXCYB and AXB formats. The LNCap tumor expresses human PSMA, resulting in tumor tissue specific accumulation of the PSMA targeted siRNA conjugates after i.v. administration, receptor mediate uptake and siRNA facilitated knockdown of the target gene.

The sequence of the guide/antisense strand was complementary to the gene sequence starting a base position 333 for the human mRNA transcript for EGFR (ACUCGUGCCUUGGCAAACUUU; SEQ ID NO: 2082). Base, sugar and phosphate modifications were used to optimize the potency of the duplex and reduce immunogenicity. All siRNA single strands were fully assembled on solid phase using standard phosphoramidite chemistry and purified over HPLC. Purified single strands were duplexed to get the double stranded siRNA. The passenger strand contained two conjugation handles, a C6-NH2 at the 5′ end and a C6-SH at the 3′ end. Both conjugation handles were connected to siRNA passenger strand via phosphorothioate-inverted abasic-phosphorothioate linker, see Example 9 for the chemical structure.


Negative control siRNA sequence (scramble): A published (Burke et al. (2014) Pharm. Res., 31(12):3445-60) 21mer duplex with 19 bases of complementarity and 3′ dinucleotide overhangs was used. The sequence (5′ to 3′) of the guide/antisense strand was UAUCGACGUGUCCAGCUAGUU (SEQ ID NO: 2116). Base, sugar and phosphate modifications were used to reduce immunogenicity and were comparable to those used in the active siRNA. All siRNA single strands were fully assembled on solid phase using standard phosphoramidite chemistry and purified over HPLC. Purified single strands were duplexed to get the double stranded siRNA. The passenger strand contained two conjugation handles, a C6-NH2 at the 5′ end and a C6-SH at the 3′ end. Both conjugation handles were connected to siRNA passenger strand via a phosphodiester-inverted abasic-phosphodiester linker, see Example 9 for the chemical structure.


ASC Synthesis and Characterization


The AXBYC conjugate used in groups 3-5 and 7 was made and purified as a DAR1 (n=1) using ASC architecture-4, as described in Example 9. The AXB (groups 1-2) and AXCYB (group 6) conjugates were made as described in Example 9.


In Vivo Study Design


Groups (n=5) of female SCID SHO mice bearing subcutaneous flank LNCaP tumors 100-350 mm3 in volume were treated with one intravenous (i.v.) tail vein injection of siRNA conjugate, while control groups (n=5) of the same mice received one i.v. injection of PBS as a vehicle control. Treatment groups 1-6 were dosed at 1.0 or 0.5 mg/kg (based on the weight of siRNA) as per the study design below. All groups (treatments and controls) were administered a dose volume of 5 mL/kg. Mice were sacrificed by CO2 asphyxiation at 96 hours post-dose. Table 23 describes the study design in more detail. 50 mg pieces of tumor and liver, were collected and snap-frozen in liquid nitrogen. mRNA knockdown in target tissue was determined using a comparative qPCR assay as described in Example 2. Total RNA was extracted from the tissue, reverse transcribed and mRNA levels were quantified using TaqMan qPCR, using the appropriately designed primers and probes. PPIB (housekeeping gene) was used as an internal RNA loading control, results were calculated by the comparative Ct method, where the difference between the target gene Ct value and the PPIB Ct value (ΔCt) is calculated and then further normalized relative to the PBS control group by taking a second difference (ΔΔCt). Quantitation of tissue siRNA concentrations were determined using a stem-loop qPCR assay as described in Example 2. The antisense strand of the siRNA was reverse transcribed using a TaqMan MicroRNA reverse transcription kit using a sequence-specific stem-loop RT primer. The cDNA from the RT step was then utilized for real-time PCR and Ct values were transformed into plasma or tissue concentrations using the linear equations derived from the standard curves.

The orientation of the siRNA and PEG relative to the PSMA-Ab was also explored in an in vivo mouse tumor model. As illustrated in FIG. 51A, having the siRNA in between the PSMA-Ab and the PEG5k (PSMA-Ab(Cys)-EGFR-PEG5k or AXBYC format)) resulted in higher levels of EGFR mRNA knockdown in the tumor relative to the alternative conjugate where PEG5k is in between the PSMA-Ab and the siRNA (PSMA-Ab(Cys)-PEG5k-EGFR or AXCYB format). This approach (AXBYC) also resulted in higher levels of EGFR mRNA knockdown in the tumor relative to the conjugate without PEG5K (PSMA-Ab(Cys)-EGFR or AXB format).


The orientation of the siRNA and PEG relative to the PSMA-Ab was also explored relative to the tissue PK profiles. Tissue concentrations were measured pmol/g and then converted to pmol/mL by assuming the density of tissue equals 1 g/mL (a concentration of 1 nM=1 nmol/L=1 pmol/mL=1 pmol/g tissue). As illustrated in FIG. 51B, having the siRNA in between the PSMA-Ab and the PEG5k (PSMA-Ab(Cys)-EGFR-PEG5k or AXBYC) resulted in higher levels of siRNA delivery to the tumor relative to the alternative conjugate where PEG5k is in between the PSMA-Ab and the siRNA (PSMA-Ab(Cys)-PEG5k-EGFR or AXCYB). This approach (AXBYC) also resulted in higher levels of EGFR siRNA delivery to the tumor relative to the conjugate without PEG5K (PSMA-Ab(Cys)-EGFR or AXB).


In a mouse LNCaP subcutaneous xenograph model, it was demonstrated that the AXBYC format for the antibody siRNA conjugate results in higher levels of siRNA accumulation in the tumor tissue and a greater magnitude of EGFR mRNA knockdown, relative to the AXCYB and AXB formats. The LNCap tumor expresses human PSMA, resulting in tumor tissue specific accumulation of the PSMA targeted siRNA conjugates after i.v. administration, receptor mediate uptake and siRNA facilitated knockdown of the target gene.

In Vivo Study Design


Groups (n=4) of wild-type female CD-1 mice were treated with one intravenous (i.v.) tail vein injections of siRNA conjugates. Treatment groups received 0.5 mg/kg (based on the weight of siRNA) and all groups were administered a dose volume of 5.0 mL/kg. Table 24 illustrates the study design in more detail. Non-terminal blood samples were collected at 5, 30, and 180 minutes post-dose via puncture of the retro-orbital plexus and centrifuged to generate plasma for PK analysis. Mice were sacrificed by CO2 asphyxiation at 24, 96, or 168 h post-dose. Terminal blood samples were collected via cardiac puncture and processed to generate plasma for PK analysis. Quantitation of plasma siRNA concentrations were determined using a stem-loop qPCR assay as described in Example 2. The antisense strand of the siRNA was reverse transcribed using a TaqMan MicroRNA reverse transcription kit using a sequence-specific stem-loop RT primer.

In this in vivo PK experiment the orientation of the siRNA and PEG relative to the EGFR-Ab was explored to determine the behavior of the mAb-siRNA conjugate in plasma. As illustrated in FIG. 52, all the mAb-siRNA conjugates (AXB, AXBYC and AXCYB formats) had comparable plasma PK with approximately 10% of the siRNA remaining in the systemic circulation after 168 hours (7 days), compared to the siRNA-PEG5K (BYC format) which was rapidly cleared from the plasma.


The AXBYC format for the antibody siRNA conjugate has improved PK properties relative the siRNA-PEG conjugate (BYC) which was rapidly cleared from the plasma.

Treatment groups 1-3 and 4-6 were dosed at 1.0, 0.5 or 0.25 mg/kg (based on the weight of siRNA) as per the study design below. As described in Example 9, groups 1-3 contained the same targeting antibody, but groups 4-6 had a different EGFR targeting antibody, while the rest of the conjugate components (linker, siRNA and PEG) were identical.

siRNA concentrations were determined 96 hours in the tumor and liver after a single i.v. injection at 1.0, 0.5 and 0.25 mg/kg. Tissue concentrations were measured pmol/g and then converted to pmol/mL by assuming the density of tissue equals 1 g/mL. In FIG. 53A, a concentration of 1 nM=1 nmol/L=1 pmol/mL=1 pmol/g tissue. As illustrated in FIG. 53A, both antibody conjugates were capable of delivering higher levels of siRNA to the tumor relative to the liver, and a dose response was observed. The EGFR antibody conjugate was capable of delivering more siRNA to the tumor tissue, at all the doses tested, relative to the EGFR2 antibody. See FIG. 53B. Both conjugates were capable of EGFR gene specific mRNA knockdown at 96 hours post-administration. The control conjugate that contained the scrambled siRNA and the PBS vehicle control did not produce significant EGFR gene specific mRNA knockdown.


As highlighted in FIG. 54, biological activity was demonstrated with the A-X-B-Y-C conjugate with a range of different antibodies and siRNA cargos that are capable of in vivo biological activity in a range of different tissue targets. In this example, it was demonstrated that tumor specific accumulation of 2 conjugates targeted with two different EGFR antibodies conjugated to an siRNA designed to down regulate EGFR mRNA. The HCC827 tumor expresses high levels of human EGFR and both conjugates have a human specific EGFR antibody to target the siRNA, resulting in tumor tissue specific accumulation of the conjugates. Receptor mediate uptake resulted in siRNA mediated knockdown of the target gene.

In this in vivo PD experiment, it was demonstrated that dose dependent EGFR gene specific mRNA knockdown (FIG. 55) at 96 hour's post-administration with a third example of an EGFR antibody targeting agent (EGFR3). The control conjugate that contained the scrambled siRNA and the PBS vehicle control did not produce significant EGFR gene specific mRNA knockdown.


As highlighted in FIG. 54, it was demonstrated that biological activity with the A-X-B-Y-C conjugate with a range of different antibodies and siRNA cargos that are capable of in vivo biological activity in a range of different tissue targets. In this example, it was demonstrated that tumor specific down regulation of EGFR mRNA using a third EGFR antibody targeting ligand. The HCC827 tumor expresses human EGFR and both conjugates have a human specific EGFR antibody (EGFR and EGFR3) to target the siRNA, resulting in tumor tissue specific accumulation of the conjugates. Receptor mediate uptake resulted in siRNA mediated knockdown of the target gene.

siRNA Design and Synthesis


EFGR: A 21mer duplex with 19 bases of complementarity and 3′ dinucleotide overhangs was designed against human EGFR. The sequence (5′ to 3′) of the guide/antisense strand was TCUCGUGCCUUGGCAAACUUU (SEQ ID NO: 2117) and it was design to be complementary to the gene sequence starting a base position 333 for the human mRNA transcript for EGFR. Base, sugar and phosphate modifications were used to optimize the potency of the duplex and reduce immunogenicity. All siRNA single strands were fully assembled on solid phase using standard phosphoramidite chemistry and purified over HPLC. Purified single strands were duplexed to get the double stranded siRNA. The passenger strand contained two conjugation handles, a C6-NH2 at the 5′ end and a C6-SH at the 3′ end. Both conjugation handles were connected to siRNA passenger strand via phosphorothioate-inverted abasic-phosphorothioate linker, see Example 9 for the chemical structure.


Negative control siRNA sequence (scramble): A published (Burke et al. (2014) Pharm. Res., 31(12):3445-60) 21mer duplex with 19 bases of complementarity and 3′ dinucleotide overhangs was used. The sequence (5′ to 3′) of the guide/antisense strand was UAUCGACGUGUCCAGCUAGUU (SEQ ID NO: 2116). Base, sugar and phosphate modifications were used to reduce immunogenicity and were comparable to those used in the active siRNA.

Both conjugation handles were connected to siRNA passenger strand via a phosphodiester-inverted abasic-phosphodiester linker, see Example 9 for the chemical structure.


ASC Synthesis and Characterization


All conjugates were made and purified as a DAR1 (n=1) using ASC architecture-4, as described in Example 9.


In Vivo Study Design


Groups (n=5) of female NCr nu/nu mice bearing subcutaneously (SC) flank HCC827 tumors 100-300 mm3 in volume were treated with one intravenous (i.v.) tail vein injection of siRNA conjugate, while control group 10 (n=5) of the same mice received one i.v. injection of PBS as a vehicle control. Treatment groups 1-3, 4-6 and 7-9 were dosed at 1.0, 0.5 or 0.25 mg/kg (based on the weight of siRNA), as per the study design below. As described in Example 9, groups 1-3 contained the same targeting antibody (EGFR3) but groups 4-9 had a different EGFR targeting antibody, while the rest of the conjugate components (linker, siRNA and PEG) were identical. Group 7-9 received an antibody conjugate with a negative control siRNA sequence (scramble) as a control for groups 1-6. All groups (treatments and controls) were administered a dose volume of 5 mL/kg. Mice were sacrificed by CO2 asphyxiation at 96 hours post-dose. Table 27 describes the study design in more detail. 50 mg pieces of tumor and liver, were collected and snap-frozen in liquid nitrogen. mRNA knockdown in target tissue was determined using a comparative qPCR assay as described in Example 2. Total RNA was extracted from the tissue, reverse transcribed and mRNA levels were quantified using TaqMan qPCR, using the appropriately designed primers and probes. PPIB (housekeeping gene) was used as an internal RNA loading control, results were calculated by the comparative Ct method, where the difference between the target gene Ct value and the PPIB Ct value (ΔCt) is calculated and then further normalized relative to the PBS control group by taking a second difference (ΔΔCt). Quantitation of tissue siRNA concentrations were determined using a stem-loop qPCR assay as described in Example 2. The antisense strand of the siRNA was reverse transcribed using a TaqMan MicroRNA reverse transcription kit using a sequence-specific stem-loop RT primer. The cDNA from the RT step was then utilized for real-time PCR and Ct values were transformed into plasma or tissue concentrations using the linear equations derived from the standard curves.

siRNA concentrations were determined 96 hours in the tumor and liver after a single i.v. injection at 1.0, 0.5 and 0.25 mg/kg. Tissue concentrations were measured pmol/g and then converted to pmol/mL by assuming the density of tissue equals 1 g/mL. In FIG. 56A, a concentration of 1 nM=1 nmol/L=1 pmol/mL=1 pmol/g tissue. As illustrated in FIG. 56A, both antibody conjugates were capable of delivering higher levels of siRNA to the tumor relative to the liver, and a dose response was observed. Both conjugates were capable of EGFR gene specific mRNA knockdown at 96 hours post-administration relative to the scramble and vehicle control. See FIG. 56B.


As highlighted in FIG. 54, it was demonstrated biological activity with the A-X-B-Y-C conjugate with a range of different antibodies and siRNA cargos that are capable of in vivo biological activity in a range of different tissue targets. In this example, it was demonstrated tumor specific accumulation of 2 conjugates targeted with two different EGFR antibodies conjugated to an siRNA designed to down regulate EGFR mRNA. The HCC827 tumor expresses high levels of human EGFR and both conjugates have a human specific EGFR antibody to target the siRNA, resulting in tumor tissue specific accumulation of the conjugates. Receptor mediate uptake resulted in siRNA mediated knockdown of the target gene


Example 16: 2016-PK-237-HCC827

siRNA Design and Synthesis


KRAS: A 21mer duplex with 19 bases of complementarity and 3′ dinucleotide overhangs was designed against human KRAS. The sequence of the guide/antisense strand was complementary to the gene sequence starting a base position 237 for the human mRNA transcript for KRAS (UGAAUUAGCUGUAUCGUCAUU; SEQ ID NO: 2088). Base, sugar and phosphate modifications were used to optimize the potency of the duplex and reduce immunogenicity. All siRNA single strands were fully assembled on solid phase using standard phosphoramidite chemistry and purified over HPLC. Purified single strands were duplexed to get the double stranded siRNA. The passenger strand contained two conjugation handles, a C6-SH at the 3′ end, which was connected to siRNA passenger strand via via phosphodiester-inverted abasic-phosphorothioate linker. The C6-SH was connected through the phosphodiester, see Example 9 for the chemical structure. In addition, the 5′ end of the passenger strand had the inverted abasic removed and the antibody was conjugated directly to the amine on passenger strand 5′ end sugar on a T base using a procedure similar to architecture 2, see Example 9.


EFGR: A 21mer duplex with 19 bases of complementarity and 3′ dinucleotide overhangs was designed against human EGFR. The sequence of the guide/antisense strand was complementary to the gene sequence starting a base position 333 for the human mRNA transcript for EGFR (ACUCGUGCCUUGGCAAACUUU; SEQ ID NO: 2082). Base, sugar and phosphate modifications were used to optimize the potency of the duplex and reduce immunogenicity. All siRNA single strands were fully assembled on solid phase using standard phosphoramidite chemistry and purified over HPLC. Purified single strands were duplexed to get the double stranded siRNA. The passenger strand contained two conjugation handles, a C6-NH2 at the 5′ end and a C6-SH at the 3′ end. Both conjugation handles were connected to siRNA passenger strand via phosphorothioate-inverted abasic-phosphorothioate linker, see Example 9 for the chemical structure.


ASC Synthesis and Characterization


Conjugates in groups 1-3 were made and purified as a DAR1 (n=1) using ASC architecture-7, as described in Example 9.


Conjugates in groups 4-6 were made and purified as a DAR1 (n=1) using ASC architecture-4, as described in Example 9.


In Vivo Study Design


Groups (n=5) of female NCr nu/nu mice bearing subcutaneously (SC) flank HCC827 tumors 100-300 mm3 in volume were treated with one intravenous (i.v.) tail vein injection of siRNA conjugate, while control group 7 (n=5) of the same mice received one i.v. injection of PBS as a vehicle control. Treatment groups 1-3, 4-6 were dosed at 1.0, 0.5 or 0.25 mg/kg (based on the weight of siRNA), as per the study design below. As described in Example 9, groups 1-6 contained the same targeting antibody (EGFR) but groups 1-3 had an siRNA designed to downregulate KRAS and groups 4-6 had an siRNA designed to downregulate EGFR. All groups (treatments and controls) were administered a dose volume of 5 mL/kg. Mice were sacrificed by CO2 asphyxiation at 96 hours post-dose. Table 28 describes the study design in more detail. 50 mg pieces of tumor and liver, were collected and snap-frozen in liquid nitrogen. mRNA knockdown in target tissue was determined using a comparative qPCR assay as described in the methods section. Total RNA was extracted from the tissue, reverse transcribed and mRNA levels were quantified using TaqMan qPCR, using the appropriately designed primers and probes. PPIB (housekeeping gene) was used as an internal RNA loading control, results were calculated by the comparative Ct method, where the difference between the target gene Ct value and the PPIB Ct value (ΔCt) is calculated and then further normalized relative to the PBS control group by taking a second difference (ΔΔCt). Quantitation of tissue siRNA concentrations were determined using a stem-loop qPCR assay as described in Example 2. The antisense strand of the siRNA was reverse transcribed using a TaqMan MicroRNA reverse transcription kit using a sequence-specific stem-loop RT primer. The cDNA from the RT step was then utilized for real-time PCR and Ct values were transformed into plasma or tissue concentrations using the linear equations derived from the standard curves. Plasma concentrations of the antibody component of the conjugate were determined using an ELISA assay.

Tissue concentrations were measured pmol/g and then converted to pmol/mL by assuming the density of tissue equals 1 g/mL. In FIG. 57A and FIG. 57B, a concentration of 1 nM=1 nmol/L=1 pmol/mL=1 pmol/g tissue. As illustrated in FIG. 57A and FIG. 57B, both antibody conjugates were capable of delivering higher levels of siRNA to the tumor relative to the liver. The conjugate that contained the siRNA designed to downregulate KRAS was capable of KRAS gene specific mRNA knockdown (FIG. 57C) at 96 hours post-administration relative to the conjugate that contained the siRNA designed to down regulate EGFR or the PBS vehicle control. Both antibody conjugate constructs had similar PK properties (see FIG. 58A and FIG. 58B) indicating the alternative conjugation strategy used on the 5′ guide strand for the antibody had no impact on this biological parameter.


As highlighted in FIG. 54, it was demonstrated biological activity with the A-X-B-Y-C conjugate with a range of different antibodies and siRNA cargos that are capable of in vivo biological activity in a range of different tissue targets. In this example it was demonstrated tumor specific accumulation and siRNA mediated mRNA knockdown of a EGFR antibody conjugated to an siRNA designed to down regulate KRAS mRNA.

Negative control siRNA sequence (scramble): A published (Burke et al. (2014) Pharm. Res., 31(12):3445-60) 21mer duplex with 19 bases of complementarity and 3′ dinucleotide overhangs was used. The sequence (5′ to 3′) of the guide/antisense strand was UAUCGACGUGUCCAGCUAGUU (SEQ ID NO: 2116). Base, sugar and phosphate modifications were used to reduce immunogenicity and were comparable to those used in the active siRNA. All siRNA single strands were fully assembled on solid phase using standard phosphoramidite chemistry and purified over HPLC. Purified single strands were duplexed to get the double stranded siRNA.

In this in vivo PK experiment the plasma clearance of two different conjugates was explored. As illustrated in FIG. 62, both the mAb-siRNA conjugates had comparable plasma PK when comparing the plasma levels of the siRNA (KRAS vs EGFR) or the antibody (EGFR2 vs PSMA).


As highlighted in FIG. 54, it was demonstrated biological activity with the A-X-B-Y-C conjugate with a range of different antibodies and siRNA cargos that are capable of in vivo biological activity in a range of different tissue targets. In this example it was demonstrated that two different conjugates with different antibody targeting ligands and different siRNA cargos have comparable plasma PK properties.

EFGR: A 21mer duplex with 19 bases of complementarity and 3′ dinucleotide overhangs was designed against human EGFR. The sequence of the guide/antisense strand was complementary to the gene sequence starting a base position 333 for the human mRNA transcript for EGFR (ACUCGUGCCUUGGCAAACUUU; SEQ ID NO: 2082). Base, sugar and phosphate modifications were used to optimize the potency of the duplex and reduce immunogenicity. All siRNA single strands were fully assembled on solid phase using standard phosphoramidite chemistry and purified over HPLC. Purified single strands were duplexed to get the double stranded siRNA. The passenger strand contained two conjugation handles, a C6-NH2 at the 5′ end and a C6-SH at the 3′ end. Both conjugation handles were connected to siRNA passenger strand via phosphorothioate-inverted abasic-phosphorothioate linker, see Example 9 for the chemical structure.


ASC Synthesis and Characterization


All conjugates were made and purified as a DAR1 (n=1) or DAR2 (n=2) using ASC architecture-1, as described in Example 9.


In Vivo Study Design


Groups (n=5) of female SCID SHO mice bearing subcutaneous flank LNCaP tumors 100-350 mm3 in volume were treated with one intravenous (i.v.) tail vein injection of siRNA conjugate, while control groups (n=5) of the same mice received one i.v. injection of PBS as a vehicle control. Treatment groups were dosed as per the study design in Table 33. All groups (treatments and controls) were administered a dose volume of 5.71 mL/kg. Mice were sacrificed by CO2 asphyxiation at 72 hours post-dose. 50 mg pieces of tumor and liver, were collected and snap-frozen in liquid nitrogen. mRNA knockdown in target tissue was determined using a comparative qPCR assay as described in Example 2. Total RNA was extracted from the tissue, reverse transcribed and mRNA levels were quantified using TaqMan qPCR, using the appropriately designed primers and probes. PPIB (housekeeping gene) was used as an internal RNA loading control, results were calculated by the comparative Ct method, where the difference between the target gene Ct value and the PPIB Ct value (ΔCt) is calculated and then further normalized relative to the PBS control group by taking a second difference (ΔΔCt). Quantitation of tissue siRNA concentrations were determined using a stem-loop qPCR assay as described in Example 2. The antisense strand of the siRNA was reverse transcribed using a TaqMan MicroRNA reverse transcription kit using a sequence-specific stem-loop RT primer. The cDNA from the RT step was then utilized for real-time PCR and Ct values were transformed into plasma or tissue concentrations using the linear equations derived from the standard curves.

siRNA concentrations were determined 72 hours in the tumor and liver after a single i.v. injection, see FIG. 63A. As illustrated in FIG. 63A, the antibody conjugate with a drug to antibody ratio of 1 (n=1) was capable of delivering siRNA to the tumor in a dose dependent manner, at levels greater than measured in the liver and produced EGFR gene specific mRNA knockdown relative to the scrambled and PBS controls. This is in contrast to the antibody conjugate with a drug to antibody ratio of 2 (n=2), which achieved lower concentrations of siRNA in the tumor at an equivalent dose, liver and tumor concentrations which were of the same magnitude and a lower levels of EGFR knockdown. The unconjugated siRNA had poor tumor and liver accumulation and no measurable EGFR mRNA knockdown. FIG. 63B illustrates relative percentage of EGFR mRNA in LNCaP Tumor.


As highlighted in FIG. 54, it was demonstrated biological activity with the A-X-B-Y-C conjugate with a range of different antibodies and siRNA cargos that are capable of in vivo biological activity in a range of different tissue targets. In this example it was demonstrated that the DAR1 conjugate is able to achieve greater siRNA tumor concentrations, relative to the DAR 2 and unconjugated siRNA. In addition, the DAR1 conjugate is able to achieve greater levels of siRNA mediate knockdown of EGFR, relative to the DAR 2 and unconjugated siRNA.

As illustrated on FIG. 64A-FIG. 64C, after a single i.v. administration of an ASC dose dependent knockdown of HPRT in heart muscle, gastroc skeletal muscle and liver were measured. There was no measurable knockdown of HPRT in the lung tissue (FIG. 64D). In addition, dose dependent accumulation of the siRNA in all four tissue compartments was observed (FIG. 64E). There was no significant difference in the biological activity (KD and tissue concentration) between the lysine and cysteine conjugates.


As highlighted in FIG. 54, it was demonstrated biological activity with the A-X-B-Y-C conjugate with a range of different antibodies and siRNA cargos that are capable of in vivo biological activity in a range of different tissue targets. In this example it was demonstrated that an anti-B cell antibody can be used to target an siRNA to heart muscle, gastroc skeletal muscle and liver and achieve gene specific downregulation of the reporter gene HPRT. There was no measurable difference in the biological activity of the ASC constructs when a lysine or cysteine conjugation strategy was use to attach to the antibody.

As illustrated in FIG. 67A, after a single i.v. administration of an ASC containing a PSMA antibody targeting ligand and siRNA designed to downregulate AR, AR knockdown in the LNCaP tumor tissue at all the doses tested relative to the scrambled control was elicited. As illustrated FIG. 67B, there was measurable accumulation of siRNA in the tumor tissue and at levels higher than those measured in the liver tissue.


As highlighted in FIG. 54, it was demonstrated biological activity with the A-X-B-Y-C conjugate with a range of different antibodies and siRNA cargos that are capable of in vivo biological activity in a range of different tissue targets. In this example, it was demonstrated delivery to an LNCaP prostate tumor with a PSMA antibody conjugated to an siRNA designed to down regulate AR mRNA. LNCaP cells express human PSMA on cell surface, the conjugate has a human specific PSMA antibody that binds to the antigen and allows internalization of the siRNA, resulting in siRNA mediated knockdown of AR in the tumor tissue.

In Vitro Study Design


Mouse spleens were harvested and kept in PBS with 100 u/ml penicillin and streptomycin on ice. Spleens were smashed with clean glass slides, cut into small pieces, homogenized with 18 G needles, and filtered (70 um nylon membrane). Dead cells were removed with the dead cell removal kit from Milteny biotec (Catalog#130-090101) according to manufacturer instruction. To isolate mouse B cells, B cell isolation kit Milteny biotec (Catalog#130-090-862) was used following manufacturer instruction. Briefly, live spleen cells were resuspended with 200 μl of MACS buffer per mouse spleen. Non-B cells were depleted with biotin-conjugated monoclonal antibodies against CD43 (Ly48), CD4, and Ter-119, coupled with anti-biotin magnetic microbeads. From one mouse spleen, 30 million live B cells can be obtained. To activate isolated mouse B cells (2×106/ml in 10% FBS RPMI-1640 with 100 u/ml penicillin and streptomycin), a cocktail of 10 μg/ml LPS, 5 μg/ml anti-IgM, 1 μg/ml anti-CD40, 0.05 μg/ml IL-4, and 0.05 μg/ml INFγ was added. After four hours of activation, ASCs (1 pM to 10 nM) were added to 106 cells per well in 24 (0.5 ml media) or 12 (1 ml media) well plates. After 48 hours of ASC treatments, cells were harvested and isolated RNAs were analyzed for mRNA knockdown.

In this in vitro experiment in activated primary mouse B cells, the ability of an anti-B cell antibody and Fab ASCs to deliver an siRNA design to downregulate Hypoxanthine-guanine phosphoribosyltransferase (HPRT) was measured. As illustrated in FIG. 68A, the Fab conjugate was able to downregulate HPRT relative to the vehicle or scramble controls. As illustrated in FIG. 68B, the antibody conjugate was able to downregulate HPRT relative to the antibody, vehicle, and scramble controls.


As highlighted in FIG. 54, it was demonstrated biological activity with the A-X-B-Y-C conjugate with a range of different antibodies and siRNA cargos that are capable of in vivo biological activity in a range of different tissue targets. In this example, it was demonstrated delivery to an activated mouse B cell with a mouse anti-B cell antibody or anti-B cell Fab conjugated to an siRNA designed to down regulate HPRT mRNA. Activated mouse B cells recognize and internalize the antibody-siRNA conjugate via surface receptors that recognize the anti-B cell antibody, resulting in siRNA mediated knockdown of HPRT.

siRNA Design and Synthesis


EFGR: A 21mer duplex with 19 bases of complementarity and 3′ dinucleotide overhangs was designed against human EGFR. The sequence of the guide/antisense strand was complementary to the gene sequence starting a base position 333 for the human mRNA transcript for EGFR (ACUCGUGCCUUGGCAAACUUU; SEQ ID NO: 2082). Base, sugar and phosphate modifications were used to optimize the potency of the duplex and reduce immunogenicity. All siRNA single strands were fully assembled on solid phase using standard phosphoramidite chemistry and purified over HPLC. Purified single strands were duplexed to get the double stranded siRNA. The passenger strand contained two conjugation handles, a C6-NH2 at the 5′ end and a C6-SH at the 3′ end. Both conjugation handles were connected to siRNA passenger strand via phosphorothioate-inverted abasic-phosphorothioate linker, see Example 9 for the chemical structure.


KRAS: A 21mer duplex with 19 bases of complementarity and 3′ dinucleotide overhangs was designed against human EGFR. The sequence of the guide/antisense strand was complementary to the gene sequence starting a base position 237 for the human mRNA transcript for KRAS (UGAAUUAGCUGUAUCGUCAUU; SEQ ID NO: 2088). Base, sugar and phosphate modifications were used to optimize the potency of the duplex and reduce immunogenicity. All siRNA single strands were fully assembled on solid phase using standard phosphoramidite chemistry and purified over HPLC. Purified single strands were duplexed to get the double stranded siRNA. The passenger strand contained two conjugation handles, a C6-NH2 at the 5′ end and a C6-SH at the 3′ end. Both conjugation handles were connected to siRNA passenger strand via phosphorothioate-inverted abasic-phosphorothioate linker, see Example 9 for the chemical structure.


ASC Synthesis and Characterization


The conjugate for groups 1-2 were made and purified as a DAR1 (n=1) using ASC architecture-4, as described in Example 9. The conjugate for groups 3-4 were made and purified as a DAR2 (n=2) using ASC architecture-4, as described in Example 9. The conjugate for groups 5-6 were made and purified as a DAR1 (n=1) using ASC architecture-5, as described in Example 9. The conjugate for groups 7-8 were made and purified as a DAR2 (n=2) using ASC architecture-5, as described in Example 9. The conjugate for groups 9-10 were made and purified as a DAR1 (n=1) using ASC architecture-6, as described in Example 9. The conjugate for groups 11-12 were made and purified as a DAR2 (n=2) using ASC architecture-6, as described in Example 9.


In Vivo Study Design


Groups (n=4) of wild-type female CD-1 mice were treated with one intravenous (i.v.) tail vein injections of siRNA conjugates (groups 1-12) or antibody alone (groups 13-14). Table 39 illustrates the study design. Non-terminal blood samples were collected at 0.25, and 3 hours post-dose via puncture of the retro-orbital plexus and centrifuged to generate plasma for PK analysis. Mice were sacrificed by CO2 asphyxiation at 24 and 72 hours post-dose. Terminal blood samples were collected via cardiac puncture and processed to generate plasma for PK analysis. Quantitation of plasma siRNA concentrations were determined using a stem-loop qPCR assay as described in Example 2. The antisense strand of the siRNA was reverse transcribed using a TaqMan MicroRNA reverse transcription kit using a sequence-specific stem-loop RT primer. The cDNA from the RT step was then utilized for real-time PCR and Ct values were transformed into plasma or tissue concentrations using the linear equations derived from the standard curves. Plasma concentrations of antibody were determined using an ELISA assay.

In this in vivo PK study it was demonstrated the utility of site specific conjugation. As illustrated in FIG. 69A, the DAR1 (n=1) test article (group 9) had a comparable siRNA plasma clearance profile to the two controls (groups 1 and 5), with approximately 10% of the siRNA remaining in the plasma after 168 hours. All the DAR2 (n=2) conjugates had much faster clearance of the siRNA from the plasma relative to the DAR1 conjugates. As illustrated in FIG. 69B, the DAR1 (n=1) test article (group 9) had a comparable EGFR-Ab plasma clearance profile to the two controls (groups 1 and 5). All the DAR2 (n=2) conjugates had much faster clearance of the antibody from the plasma relative to the DAR1 conjugates.


In the above Examples, it was demonstrated the use of lysine and cysteine conjugation strategies to attach the siRNA to the antibody. In this example, it was demonstrated the utility of a site specific conjugation strategy and demonstrate the conjugate has comparable PK properties to non-specific conjugation strategies.

In Vivo Study Design


Groups (n=5) of female NCr nu/nu mice bearing subcutaneously (SC) flank HCC827 tumors 100-300 mm3 in volume were treated with one intravenous (i.v.) tail vein injection of siRNA conjugate, while control group (n=5) of the same mice received one i.v. injection of PBS as a vehicle control. Table 40 describes the study design. Mice were sacrificed by CO2 asphyxiation at 96 hours post-dose. 50 mg pieces of tumor and liver, were collected and snap-frozen in liquid nitrogen. mRNA knockdown in target tissue was determined using a comparative qPCR assay as described in Example 2. Total RNA was extracted from the tissue, reverse transcribed and mRNA levels were quantified using TaqMan qPCR, using the appropriately designed primers and probes. PPIB (housekeeping gene) was used as an internal RNA loading control, results were calculated by the comparative Ct method, where the difference between the target gene Ct value and the PPIB Ct value (ΔCt) is calculated and then further normalized relative to the PBS control group by taking a second difference (ΔΔCt). Quantitation of plasma and tissue siRNA concentrations were determined using a stem-loop qPCR assay as described in Example 2. The antisense strand of the siRNA was reverse transcribed using a TaqMan MicroRNA reverse transcription kit using a sequence-specific stem-loop RT primer.

In this in vivo PK study, replacing the SMCC linker between the antibody and siRNA with an enzymatically cleavable linker and the introduction of a cleavable disulfide linker between the siRNA and PEG, or the combination of both were tested. As illustrated in FIG. 70A, all the linker combination were capable of EGFR mRNA knockdown in the HCC827 tumor cells relative to the scrambled control. As illustrated in FIG. 70B, all the linker combinations produced comparable siRNA tissue accumulation in the tumor and liver. As illustrated in FIG. 70C, all the conjugates were capable of maintaining high levels of siRNA in the plasma, with approximately 10% remaining in the plasma after 168 hours.


In this AXBYC example, it was demonstrated that different linker combinations (“X” and/or “Y”) can be used to conjugate the siRNA to the antibody and PEG.

In this in vivo PK study, a disulfide (SS), enzymatically cleavable (ECL) or SMCC linker was used between the antibody and siRNA. As illustrated in graph 1 on slide 42, the tumor tissue accumulation of the siRNA was reduced when the cleavable disulfide leaker was used instead of the ECL or SMCC linkers. As illustrated on graph 2 on slide 42, the ECL linker strategy produced EGFR mRNA knockdown in the LNCaP tumor cells relative to the scrambled control. However, the SS linker failed to produce EGFR mRNA knockdown in the LNCaP tumor cells relative to the scrambled control. In addition to these linker experiments, the feasibility of −80° C. storage of the ASC was examined. The Formulation was snap-frozen in liquid nitrogen at 5 mg/ml antibody concentration, thawed at room temperature after 30 days storage at −80° C. and diluted to the required dosing concentration prior to administration. As illustrated on graph 3 on slide 42, the construct stored at −80° C., thawed prior to administration, retained its ability to produce EGFR mRNA knockdown in the LNCaP tumor cells relative to the scrambled control.


In this AXBYC example, it was demonstrated that an ECL linker (“X”) can be used to conjugate the antibody to the siRNA and that an ASC can be stored at −80° C. for 1 month and thawed prior to administration.

nu/nu mice with HCC827 tumors



Animals:









In this in vivo PK study, a disulfide or SMCC linker was used between the antibody and siRNA. As illustrated in FIG. 72A, the tumor tissue accumulation of the siRNA was reduced when the cleavable disulfide leaker was used instead of the more stable SMCC linker. As illustrated in FIG. 72B, both linker strategies were capable of producing EGFR mRNA knockdown in the HCC827 tumor cells relative to the scrambled control.


In this AXBYC example, it was demonstrated the use of a cleavable disulfide linker (“X”) between the antibody and siRNA.

siRNA Design and Synthesis


KRAS: A 21mer duplex with 19 bases of complementarity and 3′ dinucleotide overhangs was designed against human KRAS. The sequence of the guide/antisense strand was complementary to the gene sequence starting a base position 237 for the human mRNA transcript for KRAS (Guide strand sequence: UGAAUUAGCUGUAUCGUCAUU; SEQ ID NO: 2088). Base, sugar and phosphate modifications were used to optimize the potency of the duplex and reduce immunogenicity. All siRNA single strands were fully assembled on solid phase using standard phosphoramidite chemistry and purified over HPLC. Purified single strands were duplexed to get the double stranded siRNA. The passenger strand contained two conjugation handles, a C6-NH2 at the 5′ end and a C6-SH at the 3′ end.

In Vivo Study Design


Groups (n=4) of wild-type female CD-1 mice were treated with one intravenous (i.v.) tail vein injections of siRNA conjugates. Treatment groups received 0.5 mg/kg (based on the weight of siRNA) and all groups were administered a dose volume of 5.0 mL/kg. Table 43 illustrates the study design in more detail. Non-terminal blood samples were collected at 5, 30, and 180 minutes post-dose via puncture of the retro-orbital plexus and centrifuged to generate plasma for PK analysis. Mice were sacrificed by CO2 asphyxiation at 24, 96, or 168 hours post-dose. Terminal blood samples were collected via cardiac puncture and processed to generate plasma for PK analysis. Quantitation of plasma siRNA concentrations were determined using a stem-loop qPCR assay as described in Example 2. The antisense strand of the siRNA was reverse transcribed using a TaqMan MicroRNA reverse transcription kit using a sequence-specific stem-loop RT primer. The cDNA from the RT step was then utilized for real-time PCR and Ct values were transformed into plasma or tissue concentrations using the linear equations derived from the standard curves. Plasma concentrations of antibody were determined using an ELISA assay.

In this in vivo PK study, different disulfide linkers were explored, with varying degrees of steric hindrance, to understand how the rate of disulfide cleavage impacts ASC plasma PK. As illustrated in FIG. 73A, the clearance of the siRNA from the plasma was modulated by varying the degree of steric hindrance of the disulfide linker. FIG. 73B illustrates the clearance of the antibody zalutumumab from the plasma.


In this example, it was demonstrated biological activity with a range of different AXBYC conjugates in which a range of different disulfide linkers (“X”) can be used to conjugate the siRNA to the antibody.


Example 32: 2016-PK-256-WT

siRNA Design and Synthesis


KRAS: A 21mer duplex with 19 bases of complementarity and 3′ dinucleotide overhangs was designed against human KRAS. The sequence of the guide/antisense strand was complementary to the gene sequence starting a base position 237 for the human mRNA transcript for KRAS (Guide strand sequence: UGAAUUAGCUGUAUCGUCAUU; SEQ ID NO: 2088). Base, sugar and phosphate modifications were used to optimize the potency of the duplex and reduce immunogenicity. All siRNA single strands were fully assembled on solid phase using standard phosphoramidite chemistry and purified over HPLC. Purified single strands were duplexed to get the double stranded siRNA. The passenger strand contained two conjugation handles, a C6-NH2 at the 5′ end and a C6-SH at the 3′ end. Both conjugation handles were connected to siRNA passenger strand via phosphorothioate-inverted abasic-phosphorothioate linker, see Example 9 for the chemical structure.


ASC Synthesis and Characterization


All conjugates were made and purified as a DAR1 (n=1) using ASC architecture-4, as described in Example 9.


In Vivo Study Design


Groups (n=4) of wild-type female CD-1 mice were treated with one intravenous (i.v.) tail vein injections of siRNA conjugates. Treatment groups received 0.5 mg/kg (based on the weight of siRNA) and all groups were administered a dose volume of 5.0 mL/kg. Table 44 illustrates the study design in more detail. Non-terminal blood samples were collected at 0.25, 3, and 24 hours post-dose via puncture of the retro-orbital plexus and centrifuged to generate plasma for PK analysis. Mice were sacrificed by CO2 asphyxiation at 72, 96, or 168 h post-dose. Terminal blood samples were collected via cardiac puncture and processed to generate plasma for PK analysis. Quantitation of plasma siRNA concentrations were determined using a stem-loop qPCR assay as described in Example 2. The antisense strand of the siRNA was reverse transcribed using a TaqMan MicroRNA reverse transcription kit using a sequence-specific stem-loop RT primer. The cDNA from the RT step was then utilized for real-time PCR and Ct values were transformed into plasma or tissue concentrations using the linear equations derived from the standard curves. Plasma concentrations of antibody were determined using an ELISA assay.

In this in vivo PK study a range of different linkers between the antibody and siRNA were tested to determine the effect on plasma clearance. As illustrated on the graph on slide 45, all the conjugates were capable of maintaining high levels of siRNA in the plasma, with greater than 10% remaining in the plasma after 168 hours.


In this example, it was demonstrated biological activity with a range of different AXBYC conjugates in which a range of different linkers (“Y”) can be used to conjugate the siRNA to the antibody while maintaining the improved plasma kinetics over those historically observed for unconjugated siRNA.


Example 33: 2016-PK-237-HCC827

siRNA Design and Synthesis


EFGR: A 21mer duplex with 19 bases of complementarity and 3′ dinucleotide overhangs was designed against human EGFR. The sequence of the guide/antisense strand was complementary to the gene sequence starting a base position 333 for the human mRNA transcript for EGFR (Guide strad sequence: ACUCGUGCCUUGGCAAACUUU; SEQ ID NO: 2082). Base, sugar and phosphate modifications were used to optimize the potency of the duplex and reduce immunogenicity. All siRNA single strands were fully assembled on solid phase using standard phosphoramidite chemistry and purified over HPLC. Purified single strands were duplexed to get the double stranded siRNA.


Two different passenger strands were made containing two conjugation handles (C6-NH2 and C6-SH) in two different orientations (55′-EGFR-3′N and N5′-EGFR-3'S). In the N5′-EGFR-3'S passenger strand both conjugation handles were connected to siRNA passenger strand via phosphorothioate-inverted abasic-phosphorothioate linker, see Example 9 for the chemical structure. In the S5′-EGFR-3′N passenger strand both conjugation handles were connected to siRNA passenger strand via phosphodiester-inverted abasic-phosphorothioate linker. The C6-NH2 and C6-SH were connected through the phosphodiester, see Example 9 for the chemical structure.


ASC Synthesis and Characterization


The conjugate for groups 1-3 was made and purified as a DAR1 (n=1) using ASC architecture-4, as described in Example 9. The conjugate for groups 4-6 was made and purified as a DAR1 (n=1) using ASC architecture-2, as described in Example 9.


In Vivo Study Design


Groups (n=5) of female NCr nu/nu mice bearing subcutaneously (SC) flank HCC827 tumors 100-300 mm3 in volume were treated with one intravenous (i.v.) tail vein injection of siRNA conjugate, while control group (n=5) of the same mice received one i.v. injection of PBS as a vehicle control. Table 45 describes the study design. Mice were sacrificed by CO2 asphyxiation at 72, 96, and 168 hours post-dose. 50 mg pieces of tumor and liver, were collected and snap-frozen in liquid nitrogen. mRNA knockdown in target tissue was determined using a comparative qPCR assay as described in Example 2. Total RNA was extracted from the tissue, reverse transcribed and mRNA levels were quantified using TaqMan qPCR, using the appropriately designed primers and probes. PPIB (housekeeping gene) was used as an internal RNA loading control, results were calculated by the comparative Ct method, where the difference between the target gene Ct value and the PPIB Ct value (ΔCt) is calculated and then further normalized relative to the PBS control group by taking a second difference (ΔΔCt). Quantitation of tissue and plasma siRNA concentrations were determined using a stem-loop qPCR assay as described in Example 2. The antisense strand of the siRNA was reverse transcribed using a TaqMan MicroRNA reverse transcription kit using a sequence-specific stem-loop RT primer. The cDNA from the RT step was then utilized for real-time PCR and Ct values were transformed into plasma or tissue concentrations using the linear equations derived from the standard curves.

In this in vivo PK study the biological outcome of changes in the orientation of the conjugation site of the antibody and PEG (5′ or 3′) onto the siRNA were evaluated. In addition, the biological outcome of using a lysine or cysteine to attach the linker to the antibody was evaluated As illustrated FIG. 75A, both orientations of siRNA produced comparable EGFR tumor knockdown. As illustrated FIG. 75B and FIG. 75C, both orientations produced comparable siRNA tissue accumulation in the tumor and liver. As illustrated in FIG. 75D, both orientations produce a comparable plasma clearance kinetics.


As highlighted in FIG. 54, it was demonstrated biological activity with the A-X-B-Y-C conjugate with a range of different antibodies and siRNA cargos that are capable of in vivo biological activity in a range of different tissue targets. In this example, it was demonstrated that the antibody can be conjugated onto the 5′ and 3′ ends of the passenger strand of the siRNA and while maintaining the biological activity of the EGFR siRNA and tissue distribution.

In the in vivo PK study the biological outcome of changes in the orientation of the conjugation site of the antibody and PEG (5′ or 3′) onto the siRNA were evaluated. In addition, the biological outcome of using a lysine or cysteine to attach the linker to the antibody was evaluated. As illustrated in FIG. 76A-FIG. 76D, all the combinations of making the antibody conjugates produced comparable HPRT knockdown in the four tissue compartments measured. As illustrated in FIG. 77A-FIG. 77D, all the combinations of making the antibody conjugates produced comparable siRNA tissue accumulation in the different compartments measured.


In this example, it was demonstrated that a variety of different conjugation strategies to the siRNA and antibody can be used in the A-X-B-Y-C format while maintaining the biological activity of the HPRT siRNA and tissue distribution.

In Vivo Study Design


Groups (n=4) of wild-type female CD-1 mice were treated with one intravenous (i.v.) tail vein injections of siRNA conjugates. Treatment groups received 0.5 mg/kg (based on the weight of siRNA) and all groups were administered a dose volume of 5.0 mL/kg. Table 48 illustrates the study design in more detail. Non-terminal blood samples were collected at 5, 30, and 180 minutes post-dose via puncture of the retro-orbital plexus and centrifuged to generate plasma for PK analysis. Mice were sacrificed by CO2 asphyxiation at 24, 96, or 168 h post-dose. Terminal blood samples were collected via cardiac puncture and processed to generate plasma for PK analysis. Quantitation of plasma siRNA concentrations were determined using a stem-loop qPCR assay as described in Example 2. The antisense strand of the siRNA was reverse transcribed using a TaqMan MicroRNA reverse transcription kit using a sequence-specific stem-loop RT primer. The cDNA from the RT step was then utilized for real-time PCR and Ct values were transformed into plasma or tissue concentrations using the linear equations derived from the standard curves.

As illustrated in FIG. 79, all the ASC with the different cleavable linker configurations achieved equivalent plasma PK profiles, with approximately 10% of the siRNA remaining 168 hours after administration.


In this example, it was demonstrated biological activity with a range of A-X-B-Y-C conjugates in which a variety of different linker strategies (component X and Y) were used to conjugate the PEG and antibody to the siRNA passenger strand.

siRNA Design and Synthesis


EFGR: A 21mer duplex with 19 bases of complementarity and 3′ dinucleotide overhangs was designed against human EGFR. The sequence of the guide/antisense strand was complementary to the gene sequence starting a base position 333 for the human mRNA transcript for EGFR (ACUCGUGCCUUGGCAAACUUU; SEQ ID NO: 2082). Base, sugar and phosphate modifications were used to optimize the potency of the duplex and reduce immunogenicity. All siRNA single strands were fully assembled on solid phase using standard phosphoramidite chemistry and purified over HPLC. Purified single strands were duplexed to get the double stranded siRNA. The passenger strand contained two conjugation handles, a C6-NH2 at the 5′ end and a C6-SH at the 3′ end. Both conjugation handles were connected to siRNA passenger strand via phosphorothioate-inverted abasic-phosphorothioate linker, see Example 9 for the chemical structure.


Negative control siRNA sequence (scramble): A published (Burke et al. (2014) Pharm. Res., 31(12):3445-60) 21mer duplex with 19 bases of complementarity and 3′ dinucleotide overhangs was used. The sequence (5′ to 3′) of the guide/antisense strand was UAUCGACGUGUCCAGCUAGUU (SEQ ID NO: 2116). Base, sugar and phosphate modifications were used to reduce immunogenicity and were comparable to those used in the active siRNA. All siRNA single strands were fully assembled on solid phase using standard phosphoramidite chemistry and purified over HPLC. Purified single strands were duplexed to get the double stranded siRNA.

Both conjugation handles were connected to siRNA passenger strand via a phosphodiester-inverted abasic-phosphodiester linker, see Example 9 for the chemical structure.


ASC Synthesis and Characterization


All conjugates were made and purified as a DAR1 (n=1) using ASC architecture-4, as described in Example 9.


In Vivo Study Design


Groups 1-7 (n=5) of female SCID SHO mice bearing subcutaneous flank LNCaP tumors 100-350 mm3 in volume were treated with one intravenous (i.v.) tail vein injection of siRNA conjugate, while control group 8 (n=5) of the same mice received one i.v. injection of PBS as a vehicle control. Table 49 describes the study design. Mice were sacrificed by CO2 asphyxiation at 96 hours post-dose. 50 mg pieces of tumor and liver, were collected and snap-frozen in liquid nitrogen. mRNA knockdown in target tissue was determined using a comparative qPCR assay as described in Example 2. Total RNA was extracted from the tissue, reverse transcribed and mRNA levels were quantified using TaqMan qPCR, using the appropriately designed primers and probes. PPIB (housekeeping gene) was used as an internal RNA loading control, results were calculated by the comparative Ct method, where the difference between the target gene Ct value and the PPIB Ct value (ΔCt) is calculated and then further normalized relative to the PBS control group by taking a second difference (ΔΔCt). Quantitation of tissue siRNA concentrations were determined using a stem-loop qPCR assay as described in Example 2. The antisense strand of the siRNA was reverse transcribed using a TaqMan MicroRNA reverse transcription kit using a sequence-specific stem-loop RT primer. The cDNA from the RT step was then utilized for real-time PCR and Ct values were transformed into plasma or tissue concentrations using the linear equations derived from the standard curves.

As illustrated in FIG. 80A, a variety of different linkers were used between the siRNA and PEG, after i.v administration of a single dose of siRNA measurable tumor tissue EGFR downregulation was achieved relative to the negative control siRNA sequence or PBS controls. In addition, as illustrated in FIG. 80B, the different linker configurations resulted in tumor siRNA accumulation at higher levels than the other tissue samples measured (liver, spleen, lung and kidney).


In this example, it was demonstrated biological activity with a range of A-X-B-Y-C conjugates in which a variety of different linkers strategies (component Y) were used to conjugate the PEG to the siRNA passenger strand.

In Vivo Study Design


Groups (n=4) of wild-type female CD-1 mice were treated with one intravenous (i.v.) tail vein injections of siRNA conjugates. Treatment groups received 0.5 mg/kg (based on the weight of siRNA) and all groups were administered a dose volume of 5.0 mL/kg. Table 51 illustrates the study design in more detail. Non-terminal blood samples were collected at 5, 30, and 180 minutes post-dose via puncture of the retro-orbital plexus and centrifuged to generate plasma for PK analysis. Mice were sacrificed by CO2 asphyxiation at 24, 96, or 168 h post-dose. Terminal blood samples were collected via cardiac puncture and processed to generate plasma for PK analysis. Quantitation of plasma siRNA concentrations were determined using a stem-loop qPCR assay as described in Example 2. The antisense strand of the siRNA was reverse transcribed using a TaqMan MicroRNA reverse transcription kit using a sequence-specific stem-loop RT primer.

Animals:









As illustrated in FIG. 84, all the ASC with the different configurations of PEG (length and branching) achieved equivalent EGFR mRNA knockdown in the HCC827 tumor cells to the construct with the linear PEGSK at the 1 mg/kg dose. Those constructs tested in a dose response format, showed dose dependent knockdown of EGFR mRNA. As illustrated in FIG. 85, all the ASC with the different variations in linear PEG length and PEG branching achieved equivalent siRNA tumor tissue accumulation to the construct with the linear PEGSK at the 1 mg/kg dose. In addition to low liver accumulation relative to tumor, those constructs tested in a dose response format, showed dose dependent tumor tissue accumulation of siRNA.


In this example, it was demonstrated biological activity with a range of A-X-B-Y-C conjugates in which a variety of different PEG (component C) lengths and branching were used.

siRNA Design and Synthesis


HPRT: A 21mer duplex with 19 bases of complementarity and 3′ dinucleotide overhangs was designed against human HPRT. The sequence of the guide/antisense strand was AUAAAAUCUACAGUCAUAGUU (SEQ ID NO: 2082) and design to be complementary to the gene sequence starting a base position 425 for the human mRNA transcript for HPRT. Base, sugar and phosphate modifications were used to optimize the potency of the duplex and reduce immunogenicity. All siRNA single strands were fully assembled on solid phase using standard phosphoramidite chemistry and purified over HPLC. Purified single strands were duplexed to get the double stranded siRNA. The passenger strand contained two conjugation handles, a C6-NH2 at the 5′ end and a C6-SH at the 3′ end. Both conjugation handles were connected to siRNA passenger strand via phosphodiester-inverted abasic-phosphorothioate linker. The C6-NH2 and C6-SH were connected through the phosphodiester, see Example 9 for the chemical structure.


Negative control siRNA sequence (scramble): A published (Burke et al. (2014) Pharm. Res., 31(12):3445-60) 21mer duplex with 19 bases of complementarity and 3′ dinucleotide overhangs was used. The sequence (5′ to 3′) of the guide/antisense strand was UAUCGACGUGUCCAGCUAGUU (SEQ ID NO: 2116). The same base, sugar and phosphate modifications that were used for the active EGFR siRNA duplex were used in the negative control siRNA. All siRNA single strands were fully assembled on solid phase using standard phosphoramidite chemistry and purified over HPLC. Purified single strands were duplexed to get the double stranded siRNA. The passenger strand contained two conjugation handles, a C6-NH2 at the 5′ end and a C6-SH at the 3′ end. Both conjugation handles were connected to siRNA passenger strand via a phosphodiester-inverted abasic-phosphodiester linker, see Example 9 for the chemical structure.


ASC Synthesis and Characterization


Conjugates in groups 1-3 made and purified as a DAR1 (n=1) using ASC architecture-1, as described in Example 9. Conjugates in groups 4-6 were made and purified as a DAR1 (n=1) using ASC architecture-4, as described in Example 9.


In Vitro Study Design


Mouse spleens were harvested and kept in PBS with 100 u/ml penicillin and streptomycin on ice. Spleens were smashed with clean glass slides, cut into small pieces, homogenized with 18 G needles, and filtered (70 um nylon membrane). Dead cells were removed with the dead cell removal kit from Milteny biotec (Catalog#130-090101) according to manufacturer instruction. To isolate mouse B cells, B cell isolation kit Milteny biotec (Catalog#130-090-862) was used following manufacturer instruction. Briefly, live spleen cells were resuspended with 200 μl of MACS buffer per mouse spleen. Non-B cells were depleted with biotin-conjugated monoclonal antibodies against CD43 (Ly48), CD4, and Ter-119, coupled with anti-biotin magnetic microbeads. From one mouse spleen, 30 million live B cells can be obtained. To activate isolated mouse B cells (2×106/ml in 10% FBS RPMI-1640 with 100 u/ml penicillin and streptomycin), a cocktail of 10 μg/ml LPS, 5 μg/ml anti-IgM, 1 μg/ml anti-CD40, 0.05 μg/ml IL-4, and 0.05 μg/ml INFγ was added. After four hours of activation, ASCs (1 pM to 10 nM) were added to 106 cells per well in 24 (0.5 ml media) or 12 (1 ml media) well plates. After 48 hours of ASC treatments, cells were harvested and isolated RNAs were analyzed for mRNA knockdown. See Table 54 for the study design.

In this in vitro experiment in activated primary mouse B cells, the ability of an anti-B cell antibody ASCs to deliver an siRNA design to downregulate Hypoxanthine-guanine phosphoribosyltransferase (HPRT) with a range of alternative PEG polymers were measured. As illustrated in FIG. 86, the range of ASC with alternative PEGs were able to downregulate HPRT relative to the scramble control.


In this example, the biological activity was demonstrated with a range of A-X-B-Y-C conjugates in which a variety of polymer alternatives to PEG (component C) were used.


Example 43: PK-236-WT

siRNA Design and Synthesis


KRAS: A 21mer duplex with 19 bases of complementarity and 3′ dinucleotide overhangs was designed against human KRAS. The sequence of the guide/antisense strand was complementary to the gene sequence starting a base position 237 for the human mRNA transcript for KRAS (Guide strand sequence: UGAAUUAGCUGUAUCGUCAUU; SEQ ID NO: 2088). Base, sugar and phosphate modifications that are well described in the field of RNAi were used to optimize the potency of the duplex and reduce immunogenicity. All siRNA single strands were fully assembled on solid phase using standard phosphoramidite chemistry and purified over HPLC. The base at position 11 on the passenger strand had a Cy5 fluorescent label attached, as described in Example 9. Purified single strands were duplexed to get the double stranded siRNA. The passenger strand contained two conjugation handles, a C6-NH2 at the 5′ end and a C6-SH at the 3′ end. Both conjugation handles were connected to siRNA passenger strand via a phosphodiester-inverted abasic-phosphodiester linker, see Example 9 for the chemical structure.


ASC Synthesis and Characterization


Conjugates in groups 1-3 were made and purified as a DAR1 (n=1) using ASC architecture-4, as described in Example 9. Conjugates in groups 4-6 were made and purified as a DAR1 (n=1) using ASC architecture-4, but there was no PEG on the 3′ end of the passenger strand. Prior to conjugation, the 3′thiol was end-capped using N-ethylmaleimide. Conjugates in groups 7-9 were made and purified as a DAR1 (n=1) using ASC architecture-1, as described in Example 9. Conjugates in groups 10-12 made and purified as a DAR1 (n=1) using ASC architecture-1, but there was no PEG on the 5′ end of the passenger strand.


In Vivo Study Design


Groups (n=4) of wild-type female CD-1 mice were treated with one intravenous (i.v.) tail vein injections of siRNA conjugates. Treatment groups received 0.5 mg/kg (based on the weight of siRNA) and all groups were administered a dose volume of 5.0 mL/kg. Table 55 illustrates the study design in more detail. Non-terminal blood samples were collected at 0.25, 1, and 4 hours post-dose via puncture of the retro-orbital plexus and centrifuged to generate plasma for PK analysis. Mice were sacrificed by CO2 asphyxiation at 24, 48, or 72 h post-dose. Terminal blood samples were collected via cardiac puncture and processed to generate plasma for PK analysis.


Plasma samples (K2 EDTA) were processed within 4 hours after harvesting. Plasma samples were diluted with matching mouse plasma (Bioreclamation) (2-400 fold) and the concentration of CY5-siRNA in these plasma samples quantified spectroscopically using a TECAN Infinite M200 Pro (Excitation 635 nm; Emission 675 nm). To release macromolecular interactions that might quench the CY5 fluorescence, all samples were diluted 2-fold into water containing 0.01% Tween 20 and 100 ug/ml heparin prior to quantification. To determine the amount of intact ASCs in these plasma samples, plasma samples were diluted with mouse plasma to 2-50 nM CY5-siRNA and incubated with Protein G Dynabeads (Thermofisher) loaded with 150 nM of a purified EGFR-Fc protein (Sino Biological). These binding reactions were incubated at RT for 1 hour. Beads were washed twice with PBS containing 0.01% Tween 20 and 0.05% BSA before ASCs bound to EGFR were eluted by incubation in 0.1 M citric acid (pH 2.7). The amount of CY5-siRNA contained in the input, unbound fraction, washes and bead eluate was quantified by fluorescence as stated above.

In this in vivo PK study, the in vivo plasma stability of two AXBYC conjugates (cysteine and lysine conjugation to the EGFR-Ab) relative to two AXB conjugates were compared. As illustrated in FIG. 87, the concentration of the siRNA was determined using two methods. The fluorescence of the plasma was measured directly and the siRNA concentration determined using a standard curve. Or a magnetic bead decorated with EGFR was used to bind the antibody conjugates and then the fluorescence of the sample was measured and the siRNA concentration determined using a standard curve. All data were plotted as a percentage of the injected dose. In both examples of the AXBYC conjugates (cysteine and lysine conjugation to the EGFR-Ab) improved plasma PK were observed relative to the corresponding AXB conjugate.


In this example, in vivo plasma PK for the Cys and Lys AXBYC conjugates compared to the matching control AXB conjugates was demonstrate.


Example 44: In Vivo Pharmacodynamics Study of a Cholesterol-KRAS Conjugate (PD-058)

Groups (n=5) of female NCr nu/nu mice bearing intrahepatic Hep 3B tumors one week after inoculation were treated with three intravenous (i.v.) tail vein injections (separated by 48 h) of cholesterol-siRNA conjugate, while control groups (n=5) of the same mice received three i.v. injections of PBS as a vehicle control on the same dosing schedule. Treatment groups that received chol-KRAS were dosed at 10, 4, or 2 mg/kg. All groups (treatments and controls) were administered a dose volume of 6.25 mL/kg. Table 56 describes the study design in more detail and gives a cross-reference to the conjugate synthesis and characterization. Mice were sacrificed by CO2 asphyxiation at 72 h post-final dose. 50 mg pieces of tumor-bearing liver were collected and snap-frozen in liquid nitrogen. mRNA knockdown analysis and siRNA quantitation were performed as described in Examples 2-7.

The chol-KRAS conjugate was assessed for mRNA knockdown in a 3-dose study with a dose response. As illustrated in FIG. 35, within the mouse liver tissue there was a clear dose-response for mouse KRAS mRNA knockdown. The lowest dose of 2 mg/kg resulted in 45% knockdown of mouse KRAS, while the highest dose of 10 mg/kg resulted in 65% knockdown of mouse KRAS in this 3-dose format. However, there were not enough human tumor cells in the mouse liver at the time of harvest to detect a signal from human KRAS (potentially due to model development issues, it appeared that not enough human cells were inoculated to produce fast-growing tumors). As such, it was not possible to measure the knockdown in tumor.


Example 45: In Vivo Pharmacokinetics Study of a Cholesterol-siRNA Conjugate (PK-063)

Groups (n=3) of wild-type female CD-1 mice were treated with either one or two intravenous (i.v.) tail vein injections of chol-siRNA conjugate. Treatment groups received chol-KRAS at 10 mg/kg (based on the weight of siRNA) and the 2-dose groups received the second dose 48 h after the first dose. All groups were administered a dose volume of 6.25 mL/kg. Table 57 illustrates the study design in more detail and gives a cross-reference to the conjugate synthesis and characterization. Non-terminal blood samples were collected at 2, 15, 60 or 120 minutes post-final dose via puncture of the retro-orbital plexus and centrifuged to generate plasma for PK analysis. Mice were sacrificed by CO2 asphyxiation at 4, 24, 96, or 144 h post-final dose. Terminal blood samples were collected via cardiac puncture and processed to generate plasma for PK analysis. 50 mg pieces of tumor, liver, kidney, and lung were collected and snap-frozen in liquid nitrogen. mRNA knockdown analysis and siRNA quantitation were performed as described in Examples 2-7.

The pharmacokinetic behavior of chol-siRNA was assessed in a single-dose format compared to a 2-dose format. As illustrated from FIG. 36, the plasma PK profiles for the first dose and a second dose following 48 h later are nearly identical. The mechanism for clearance from plasma has not saturated from the first dose and the second dose behaves similarly. The tissue PK for 3 major tissues (the liver, kidneys, and lungs) was similarly assessed. As illustrated from FIG. 37, chol-KRAS was delivered to liver in the highest concentrations, with kidneys and lungs having approximately 10-fold lower siRNA concentrations compared to liver. For all three tissues, the siRNA concentrations following the second doses were higher than the siRNA concentrations following the first dose, demonstrating that there is accumulation of siRNA in tissues when doses of chol-siRNA are spaced by 48 h.


In Vivo Study a Cholesterol-siRNA Conjugate (PK-067).


Groups (n=3) of female NCr nu/nu mice bearing subcutaneous flank H358 tumors 100-150 mm3 in volume were treated with one intravenous (i.v.) tail vein injection of siRNA conjugate, while control groups (n=4) of the same mice received one i.v. injection of PBS as a vehicle control. Treatment groups that received cholesterol-siRNA conjugates were dosed at 5 mg/kg (based on the weight of siRNA). Some treatment groups also received cholesterol-peptide conjugates at specified molar peptide:siRNA ratios, where all chol-siRNA and chol-peptide conjugates were mixed together in solution and co-injected. All groups (treatments and controls) were administered a dose volume of 5 mL/kg. Table 58 shows the study design in more detail and gives a cross-reference to the conjugate synthesis and characterization. Mice were sacrificed by CO2 asphyxiation at 24, 72, or 144 h post-dose. 50 mg pieces of tumor, liver, kidneys, and lungs were collected and snap-frozen in liquid nitrogen. mRNA knockdown analysis and siRNA quantitation were performed as described in Examples 2-7.

Endosomolytic moieties (EEPs) such as INF7 and melittin were conjugated to cholesterol, mixed with chol-siRNA, and then co-injected into mice to demonstrate an increase in siRNA potency due to the improved endosomal escape. First, the effect of adding the EEPs on the siRNA concentration in various tissues was assessed. As illustrated in FIG. 38A, the addition of chol-INF7 at any of the molar ratios of EEP:siRNA did not affect the siRNA tumor PK. However, as illustrated in FIG. 38B, the addition of chol-melittin at a 1:1 ratio did not affect the tumor PK but the addition of chol-melittin at a 3:1 EEP:siRNA ratio decreased the amount of siRNA in tumor. As illustrated in FIG. 39, neither chol-INF7 nor chol-melittin had much of an impact on the liver PK. Similarly, as illustrated in FIGS. 40 and 41, the chol-INF7 and chol-melittin also did not have much of an impact on the PK profile in kidneys and lungs. Finally, the effect of the chol-EEP conjugates on mRNA KD was assessed and, as shown in FIG. 42, the baseline level of knockdown for chol-KRAS alone was approximately 50%. The addition of 1:1 chol-melittin or 3:1 chol-INF7 improves the knockdown at each time point, due to improved endosomal escape.


In Vivo Study a Cholesterol-siRNA Conjugate (PK-076).


Groups (n=5) of female NCr nu/nu mice bearing subcutaneous flank H358 tumors 100-150 mm3 in volume were treated with three intravenous (i.v.) tail vein injections of siRNA conjugate separated by 48 h, while control groups (n=5) of the same mice received three i.v. injections of PBS as a vehicle control on the same dosing schedule. Treatment groups that received cholesterol-siRNA conjugates were dosed at 5 mg/kg (based on the weight of siRNA). Some treatment groups also received cholesterol-peptide conjugates at specified molar peptide:siRNA ratios, where all chol-siRNA and chol-peptide conjugates were mixed together in solution and co-injected. All groups (treatments and controls) were administered a dose volume of 5 mL/kg. Table 59 describes the study design in more detail and gives a cross-reference to the conjugate synthesis and characterization. Mice were sacrificed by CO2 asphyxiation at 24 or 96 h post-dose. 50 mg pieces of tumor, liver, kidneys, and lungs were collected and snap-frozen in liquid nitrogen. mRNA knockdown analysis and siRNA quantitation were performed as described in Examples 2-7.

The activity seen in the single-dose study with chol-siRNA and chol-EEP was followed up with a three dose study. The 3:1 ratio of EEP:siRNA was selected for INF7, and the 1:1 ratio was selected for melittin. As illustrated in FIG. 43 and FIG. 44, the addition of either chol-EEP to the chol-siRNA does not seem to greatly affect the tissue PK following three doses. As for the knockdown, FIG. 45 shows that addition of chol-melittin clearly improves tumor knockdown 24 h post-dose. It also shows that chol-melittin improves tumor knockdown at 96 h post-dose.


In Vivo Study a Cholesterol-siRNA Conjugate (PK-079).


Groups (n=5) of female NCr nu/nu mice bearing subcutaneous flank H358 tumors 100-150 mm3 in volume were treated with one intravenous (i.v.) tail vein injection of siRNA conjugate, while control groups (n=5) of the same mice received one i.v. injection of PBS as a vehicle control. Treatment groups that received EGFR antibody-siRNA-PEG conjugates were dosed at 0.5 mg/kg (based on the weight of siRNA) and groups that also received EGFR antibody-melittin had the dose of EGFR-Ab matched between EGFR antibody-siRNA and EGFR antibody-melittin. All groups (treatments and controls) were administered a dose volume of 5 mL/kg. Table 60 describes the study design in more detail and gives a cross-reference to the conjugate synthesis and characterization. Mice were sacrificed by CO2 asphyxiation at 96 h post-dose. 50 mg pieces of tumor, liver, kidney, and lung were collected and snap-frozen in liquid nitrogen. mRNA knockdown analysis and siRNA quantitation were performed as described in Examples 2-7.

The PK/PD relationship for EGFR antibody-siRNA conjugates to deliver siRNA to tumor and produce mRNA knockdown in tumor was evaluated for reproducibility. As illustrated in FIG. 46, once again a single i.v. dose of 0.5 mg/kg of EGFR antibody-siRNA conjugate was able to deliver approximate 100 nM concentrations of siRNA into tumor with both configurations of the conjugate. The addition of EGFR antibody-melittin did not appear to impact the tissue PK. Out of the four tissues analyzed, tumor had the highest concentration and liver the second highest, with kidneys and lungs showing low uptake of siRNA. As illustrated in FIG. 47, the strong siRNA delivery to tumor once again translated into approximately 50% knockdown of EGFR or KRAS in the tumors. Free EGFR-Ab, run as a control group, showed no mRNA knockdown as did the PBS control.


In Vivo Study a Cholesterol-siRNA Conjugate (PD-077).


Groups (n=11) of female NCr nu/nu mice bearing intrahepatic Hep3B tumors one week after inoculation were treated with nine intravenous (i.v.) or subcutaneous (s.c.) injections (TIW) of cholesterol-siRNA conjugate, while control groups (n=11) of the same mice received nine i.v. tail vein injections of PBS as a vehicle control (also dosed TIW). Treatment groups that received chol-CTNNB1 were dosed at 5 mg/kg. All groups (treatments and controls) were administered a dose volume of 6.25 mL/kg. Table 61 describes the study design in more detail and gives a cross-reference to the conjugate synthesis and characterization. Non-terminal blood samples were collected once per week via puncture of the retro-orbital plexus and processed to generate serum for alpha-Fetoprotein (AFP) measurement. Mice were sacrificed by CO2 asphyxiation at 24 h post-final dose. 50 mg pieces of tumor-bearing liver were collected and snap-frozen in liquid nitrogen. mRNA knockdown analysis was performed as described above. AFP was quantified using the Human alpha-Fetoprotein DuoSet ELISA kit (R&D Systems) according to the manufacturer's instructions.

Since earlier studies demonstrated that it was possible for a single dose of chol-siRNA to generate knockdown in normal liver, it was hypothesized that knockdown could be achieved in orthotopic liver tumors as well. Mice were inoculated with intrahepatic Hep3B tumors that were allowed to grow for one week post-inoculation, and then these mice were administered 5 mg/kg doses of chol-CTNNB1 (either i.v. or s.c.) three times a week for three weeks (9 total doses). As illustrated in FIG. 48, the chol-CTNNB1 dosed s.c. was able to produce >50% mRNA knockdown at the harvest time point of 24 h post-final dose. In contrast, the chol-CTNNB1 siRNA that was dosed i.v. does not seem to show any mRNA knockdown at this time point (although some mice did not have any measurable human CTNNB1 signal, it was hard to determine if the loss of signal was related to knockdown or low tumor burden). The human Hep3B cells are also known to secrete human alpha-Fetoprotein (AFP), and it is known that the amount of secreted AFP correlates with the number of Hep3B cells. Thus, the concentration of AFP in serum is taken as a marker of tumor load in the mouse, and the increase in AFP over time correlates with tumor growth. As illustrated in FIG. 49, the chol-CTNNB1 dosed s.c. markedly reduced the AFP levels in those mice, which provides evidence that the CTNNB1 mRNA knockdown led to the inhibition of tumor growth.


Example 46. Liver PK/PD Study

Female wild-type CD-1 mice will be dosed with chol-siRNA-EEP conjugates at 5 mg/kg (based on the weight of siRNA). In these studies the siRNA used will be against the mouse Factor VII (FVII) such that FVII knockdown can be determined by measuring the FVII protein levels in plasma. Multiple EEPs (endosomolytic moieties) will be used to determine the peptide sequence that demonstrates optimal endosomal escape, resulting in the best knockdown of the FVII target gene relative to the control.


Example 47. Tumor PK/PD Study

Female NCr nu/nu mice bearing subcutaneous flank H358 tumors will be dosed with EGFR antibody-siRNA-EEP conjugates at 0.5 mg/kg (based on siRNA). Multiple EEPs (endosomolytic moieties) will be used to determine the peptide sequence that demonstrates optimal endosomal escape, resulting in the best knockdown of the target gene relative to the control.


Example 48. Formulation of an ABC Conjugate with Nanoparticles

An exemplary ABC conjugate is packaged into self-assembled nanoparticles using cyclodextrin polymers (10 kDa) and an excess of non-conjugated siRNAs (ED 40-60 nm, PDI 0.1-0.2). In these particles, the exemplary ABC conjugate maintains its ability to interact with the antibody target. The stability and target binding competency of the particles in circulation in vivo is regulated through modifications of the packaging siRNAs.


Nanoparticle Formation


Nanoparticles are prepared at a final siRNA concentration of 1.6 mg/mL. siRNA containing CY5-siRNA at a ratio of 1:20 is first diluted to 2× final concentration in water. Cyclodextrin polymer (CDP) is diluted to 2× final concentration necessary to achieve a nitrogen to phosphorus ratio (N:P) of 3:1 in 10 mM phosphate buffer at neutral pH. CDP is added quickly to siRNA and is further mixed by pipetting. Particles are incubated for at least 15 minutes before dosing or analysis.


In Vitro EGFR Binding


Nanoparticles containing various amount of the exemplary ABC conjugate are diluted into Fetal calf serum to a final concentration of 10 nM and are incubated for 1 h at RT with Protein G Dynabeads (Thermofisher) loaded with 150 nM of a purified EGFR-Fc protein (Sino Biological). Beads are washed twice with PBS containing 0.01% Tween 20 and 0.05% BSA before bead-bound nanoparticles are disrupted with water containing 0.01% Tween 20 and 100 ug/ml heparin. The amount of CY5-siRNA contained in the input, unbound fraction, washes and bead eluate is quantified by fluorescence using a TECAN Infinite M200 Pro (Excitation 635 nm; Emission 675 nm).


CY5-ASC Plasma Quantification


Quantification of nanoparticles in mouse plasma is performed as illustrated in Example 43. The CY5-siRNAs bound to EGFR beads are released by using heparin to compete the electrostatic interactions between CDP and siRNAs.
