METHODS AND COMPOSITIONS FOR TREATMENT OF CANCER AND OTHER ANGIOGENESIS-RELATED DISEASES

Abstract

The present invention provides nucleic acid molecules that modulate the expression of molecules in the angiopoietin/Tie2 signaling pathway. Methods of using the nucleic acid molecules are also provided.

Description

FIELD OF THE INVENTION

The present invention is in the field of molecular biology and medicine and relates to short interfering RNA (siRNA) molecules for modulating the expression of molecules in the angiopoietin/Tie2 signaling pathway.

BACKGROUND OF THE INVENTION

The angiopoietin/Tie2 signaling pathway has been implicated in several types of cancer-induced angiogenesis. Several molecules in the Ang-Tie pathway have been identified (see, e.g., Tables 1 and 13). One of them is the receptor molecule Tie2 (Tyrosine Kinase with Immunoglobulin and EGF factor homology domains, also called TIE-2, TEK or epithelial-specific protein receptor tyrosine kinase, TEK tyrosine kinase), which is expressed almost exclusively on the surface of vascular endothelial cells (ECs) (Sato et al., 1998, Int. Immunol. 10: 1217-1227). Ligands that bind to Tie2 include angiopoietin-1 and angiopoietin-2 (Yancopoulos et al., 2000, Nature 407: 242-248).

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a bar graph depicting in vitro inhibition of human Ang-2 by siRNA molecules in human umbilical vein endothelial (HUVEC) cells at 24 hours post siRNA transfection.

Human Ang-2 gene silencing activity of human Ang-2-siRNA sequences listed in Table 11 was tested in HUVEC cells. Labels #1-#48 on the x-axis correspond to the siRNA sequences numbered 1-48 in Table 11. The HUVEC cells were transfected with the Ang-2-siRNAs using a reverse transfection based high-through-put (HTP) method with 10 nM of siRNA duplex. A luciferase specific 25-mer siRNA was used as the negative control (Luc). The effect of siRNA mediated Ang-2 knockdown was monitored by measuring the concentration of Ang-2 protein in the medium using a human Ang-2 ELISA kit (R&D). Significant inhibition of Ang-2 protein level expression in transfected HUVEC cells was observed at 24 hours post transfection with a majority of the 48 Ang-2 siRNA candidates tested.

DETAILED DESCRIPTION OF THE INVENTION

The invention provides compositions and methods for treatment of diseases with unwanted angiogenesis, often an abnormal or excessive proliferation and growth of blood vessels. Since angiogenesis also can be a normal biological process, inhibition of unwanted angiogenesis is preferably accomplished with selectivity for a pathological tissue, which preferably requires selective delivery of therapeutic molecules to the pathological tissue using targeted nanoparticles. The present invention provides compositions and methods to control angiogenesis through selective inhibition of the Ang-Tie biochemical pathway by nucleic acid molecules that induce RNA interference (RNAi), including inhibition of Ang-Tie pathway gene expression and inhibition localized at pathological angiogenic tissues. The present invention also provides compositions of and methods for using a tissue-targeted nanoparticle composition comprising polymer conjugates and further comprising nucleic acid molecules that induce RNAi.

The invention is described here in detail, but one skilled in the art will appreciate the full extent of the invention.

Nucleic Acid Molecules for Ang/Tie2Pathway Gene Inhibition

The present invention provides nucleic acid molecules with a variety of physicochemical structures for targeting and silencing genes in the Ang/Tie2 pathway by RNAi. In one embodiment, the present invention provides nucleic acid molecules that result in a reduction in Ang-1, Ang-2, or Tie2 mRNA or protein levels of at least 50%, 60%, 70%, 80%, 85%, 90%, 95, 96, 97, 98, 99 or 100%. This reduction may result up to 24 hours, up to 36 hours, up to 48 hours, up to 60 hours, or up to 72 hours post administration of the nucleic acid molecules. The nucleic acid molecules that result in this reduction may be administered at 10 nM siRNA, 5 nM siRNA, 2 nM, 1 nM, 0.5 nM, or 0.2 nM quantities. In one embodiment, the nucleic acid molecules may have an IC50 for reducing Ang-2 protein levels of 0.75 nM or less, 0.5 nM or less, or 0.4 nM or less.

The nucleic acid molecules of the invention may be dsRNA or ssRNA. In one embodiment of the invention, the nucleic acid molecules are siRNA. The nucleic acid molecules may comprise 15-50, 15-30, 19, 20, 21, 22, 23, 24 or 25 base pairs. The nucleic acid molecules may comprise 5′- or 3′-single-stranded overhangs. In a certain embodiment, the nucleic acid molecules are blunt-ended. In a preferred embodiment, the nucleic acid molecule is a double-stranded siRNA of 25 basepairs with blunt ends. Exemplary siRNA sequences of the invention targeting Ang/Tie2 pathway genes are shown in Tables 2-10. (For all sequences listed in Tables 2-10, the position is labeled such that the “A” of the ATG codon is considered to be position 1.) siRNAs with 25 basepair double-stranded RNA with blunt ends were previously found to be some of the most potent inhibitors with the greatest duration of inhibition (WO 06/110813). Additionally, incorporation of non-naturally occurring chemical analogues may be useful in some embodiments of the invention. Such analogues include, but are not limited to, 2′-O-Methyl ribose analogues of RNA, DNA, LNA and RNA chimeric oligonucleotides, and other chemical analogues of nucleic acid oligonucleotides. In some embodiments, the siRNA targets both a human mRNA as well as the homologous or analogous mRNA in other non-human mammalian species such as primates, mice or rats.

The present invention provides methods for inhibition of individual or combinations of genes active in the Ang-Tie pathway. In some embodiments, the present invention provides a method of inhibiting or reducing angiogenesis in a tissue associated with undesired angiogenesis comprising administering to the tissue siRNA molecules that target Tie2 so that expression of Tie2 is decreased. In some embodiments, the present invention provides a method of inhibiting or reducing angiogenesis in a tissue associated with undesired angiogenesis comprising administering to the tissue siRNA molecules that target Ang-1 so that expression of Ang-1 is decreased. In further embodiments, the invention provides a method of inhibiting or reducing angiogenesis in a tissue associated with undesired angiogenesis comprising administering to the tissue siRNA molecules that target Ang-2 so that expression of Ang-2 is decreased. In one embodiment, the tissue is a tumor.

Combined Ang/Tie2 Pathway Gene Inhibition

The compositions and methods of the present invention for inhibition of angiogenesis are based on several fundamental aspects. First, pathological angiogenesis is a complex process and results from interactions of multiple proteins which are abnormally expressed or over-expressed in diseased tissues. Second, nucleic acid agents that activate RNAi are highly selective in a sequence specific manner. Third, inhibition of angiogenesis by modulation of protein activity can be operative by many methods, including but not limited to an inhibition of protein function (antagonists), stimulation of protein function (agonists), reduction of protein expression levels, and post transcriptional modification of proteins. Importantly, it may be desirable in the treatment of disease to effectively shut down a particular biological pathway that is critical for disease progression, by simultaneously blocking functions of ligands and their receptors, simultaneously blocking receptor activity and the activity of down stream signaling proteins, and/or simultaneously blocking redundant elements of a pathway. Such methods may be used for treating angiogenesis-related diseases including those that involve the Ang/Tie2 pathway.

Although clinical studies have demonstrated remarkable therapeutic efficacies, the toxicities of higher dosage and long term safety are major concerns, due to the different origins, different manufacturing processes and different chemistry properties of the components.

To overcome these problems, aspects of the present invention provide compositions of and methods of using nucleic acid molecules, including siRNA oligonucleotides, to provide a unique advantage, i.e., to achieve combinatorial effects with a combination of nucleic acid molecules, including siRNAs, that target multiple disease causing genes or target different sequences in the same gene in the same treatment. One advantage of the compositions and methods of the present invention is that all siRNA oligonucleotides are very similar chemically, pharmacologically, and can be produced from the same source and using the same manufacturing process. Another advantage provided by the present invention is that multiple siRNA oligonucleotides can be formulated in a single preparation such as a nanoparticle preparation.

Therefore, an aspect of the present invention is to combine nucleic acid molecules, including siRNAs, so as to achieve specific and selective silencing of multiple genes in the Ang/Tie2 pathway and as a result achieve an inhibition of angiogenesis-related disease and a better clinical benefit. The present invention provides for combinations of siRNA targets including combinations of two or more targets selected from: Tie2, Ang-1 and Ang-2. The present invention also provides for combinations of siRNAs targeting one or more sequences within the same gene in the Ang/Tie2 pathway. Exemplary siRNA sequences silencing these mRNAs are listed in Tables 2-10. Such siRNA compositions may also be combined with siRNA that targets other angiogenic pathways such as the VEGF pathway, PDGF and EGF and their receptors, downstream signaling factors including RAF and AKT, and transcription factors including NFκB. Such siRNA compositions may also be combined with siRNA that target genes downstream of Tie2, Ang-1 and Ang-2.

In one embodiment a combination of siRNA inhibiting Tie2 and two of its ligands Ang-1 and Ang-2 is used.

Preparation of Nanoparticles Containing Nucleic Acid Molecules Modulating Expression of Ang/Tie2 Pathway Genes

One embodiment of the present invention provides compositions and methods for nanoparticle preparations of anti-Ang/Tie2 pathway nucleic acid molecules, including siRNAs. The nanoparticles may comprise one or more of a histidine-lysine copolymer, polyethylene glycol, or polyethyleneimine. In one embodiment of the invention, RGD-mediated ligand-directed nanoparticles may be prepared. In one method for the manufacture of RGD-mediated tissue-targeted nanoparticles containing siRNA, the targeting ligand, an RGD-containing peptide, is conjugated to a steric polymer such as polyethylene glycol, or other polymers with similar properties. This ligand-steric polymer conjugate is further conjugated to a polycation such as polyethyleneimine or other effective material such as a histidine-lysine copolymer. The conjugation can be by covalent or non-covalent bonds and the covalent bonds can be non-cleavable or they can be cleavable such as by hydrolysis or by reducing agents. A solution comprising the polymer conjugate, or comprising a mixture of a polymer conjugate with other polymer, lipid, or micelle such as materials comprising a ligand or a steric polymer or fusogen, is mixed with a solution comprising the nucleic acid, in one embodiment an siRNA targeted against specific mRNA of interest, in desirable ratios to obtain nanoparticles that contain siRNA. Such ratios may produce nanoparticles of a desired size, stability, or other characteristics.

In one embodiment, nanoparticles are formed by layered nanoparticle self-assembly comprising mixing the polymer conjugate with excess polycation and the nucleic acid. Non-covalent electrostatic interactions between the negatively charged nucleic acid and the positively charged segment of the polymer conjugate drive the self-assembly process that leads to formation of nanoparticles. This process involves simple mixing of the solutions where one of the solutions containing the nucleic acid is added to another solution containing the polymer conjugate and excess polycation followed by or concurrently with stirring. In one embodiment, the ratio between the positively charged components and the negatively charged components in the mixture is determined by appropriately adjusting the concentrations of each solution or by adjusting the volume of solution added. In another embodiment, the two solutions are mixed under continuous flow conditions using mixing apparatus such as static mixer. In this embodiment, two or more solutions are introduced into a static mixer at rates and pressures giving a ratio of the solutions, where the streams of solutions get mixed within the static mixer. Arrangements are possible for mixers to be arranged in parallel or in series.

The present invention, thus generally described, will be understood more readily by reference to the following examples, which are provided by way of illustration and are not intended to be limiting of the present invention. The invention is illustrated by the following examples but one skilled in the art will appreciate that the invention is not limited.

Example 2

High-Through-Put Screening of Human Ang-2 siRNA for Their Potency in Inhibiting Ang-2 Expression in HUVEC Cells

A reverse transfection based high-through-put (HTP) method was used to screen 48 human Ang-2 siRNAs (Table 11) for their potency in inhibiting Ang-2 expression in HUVEC cells. Briefly, 10 nM of siRNA duplex was spotted onto the bottom of a 96-well plate followed by addition of 0.25 μl of Lipofectamine™ RNAiMAX (Invitrogen). A luciferase specific 25-mer siRNA was used as the negative control. The plate was incubated at room temperature for 10-20 minutes, and 7,500 HUVEC cells in 100 ul growth medium was added to each wells. The plate was mixed gently by rocking the plate back and forth, and then incubated for 24-48 hours at 37° C. in a CO₂ incubator. The effect of siRNA mediated Ang-2 knockdown was monitored by measuring the concentration of Ang-2 protein in the medium using a human Ang-2 ELISA kit (R&D). The cell viability of the transfected cells was measured using a WST-1 assay kit (Roche) for normalization of Ang-2 concentration.

Significant inhibition of Ang-2 protein level expression in transfected HUVEC cells was observed at 24 hours post transfection with a majority of the 48 Ang-2 siRNA candidates tested (FIG. 1). At 48 hours post transfection, the inhibition effects were more profound (FIG. 2), with about 50% of the Ang-2 siRNA candidates showing a greater than 80% inhibition of Ang-2 expression compared to cells transfected with control Luc-siRNA (FIG. 3). There was no cytotoxicity in the transfected HUVEC cells that associated with knockdown of Ang-2 expression (FIG. 4).

Example 3

Confirmation of Ang-2 Gene Expression Knockdown in HUVEC Cells Transfected with 2 nM Ang-2 siRNA

In a separate experiment, 38 Ang-2 siRNA candidates that demonstrated a high percentage of Ang-2 knockdown in previous HTP screening (FIG. 1-3) were further examined for their potency in inhibiting Ang-2 expression in HUVEC cells using a reverse transfection method. Briefly, 2 nM of siRNA duplex was spotted onto the bottom of a 96-well plate followed by addition of 0.25 μl of Lipofectamine™ RNAiMAX (Invitrogen). A negative control (Ctrl-) siRNA, which has a 19-nt double-stranded region with dTdT 3′-overhangs on both strands and does not has a significant homologous sequence with any known human gene, was used as the negative control. The plate was incubated at room temperature for 10-20 minutes, and 7,500 HUVEC cells in 100 μl growth medium was added to each well. The plate was mixed gently by rocking the plate back and forth, and then incubated for 48 hours at 37° C. in a CO₂ incubator. The effect of siRNA mediated Ang-2 knockdown was monitored by measuring the concentration of Ang-2 protein in the medium using a human Ang-2 ELISA kit (R&D). The cell viability of the transfected cells was measured using a WST-1 assay kit (Roche) for normalization of Ang-2 concentration.

Significant inhibition (>90%) of Ang-2 protein level expression in transfected HUVEC cells was observed at 48 hours post transfection with a majority of the 38 Ang-2 siRNA candidates tested (FIG. 5), including many siRNA candidates with a greater than 90% knockdown of Ang-2 protein level expression (FIG. 6). In addition, 3 siRNA that target both human and mouse Ang-2 also demonstrated high potency in knocking down human Ang-2 expression (FIGS. 5 and 6). Finally, there was no cytotoxicity in the transfected HUVEC cells that associated with knockdown of Ang-2 expression (FIG. 7).

Example 4

Final Selection of Ang-2 siRNA Based on Ang-2 Gene Expression Knockdown in HUVEC Cells Transfected with 0.2 nM

In another experiment, 18 Ang-2 siRNA candidates that demonstrated a higher than 94% knockdown of Ang-2 expression in a previous experiment (FIG. 6) and 3 human/mouse Ang-2 siRNA were further examined for their potency in inhibiting Ang-2 expression in HUVEC cells using a reverse transfection method with a lower dose of siRNA. Briefly, 0.2 nM of siRNA duplex was spotted onto the bottom of a 96-well plate followed by addition of 0.25 μl of Lipofectamine™ RNAiMAX (Invitrogen). A negative control (Ctrl-) siRNA, which has a 19-nt double-stranded region with dTdT 3′-overhangs on both strands and does not has a significant homologous sequence with any known human gene, was used as the negative control. The plate was incubated at room temperature for 10-20 minutes, and 7,500 HUVEC cells in 100 μl growth medium was added to each well. The plate was mixed gently by rocking the plate back and forth, and then incubated for 48 hours at 37° C. in a CO₂ incubator. The effect of siRNA mediated Ang-2 knockdown was monitored by measuring the concentration of Ang-2 protein in the medium using a human Ang-2 ELISA kit (R&D). The cell viability of the transfected cells was measured using a WST-1 assay kit (Roche) for normalization of Ang-2 concentration.

When transfected with only 0.2 nM of siRNA, significant inhibition (30-50%) of Ang-2 protein level expression in transfected HUVEC cells was observed at 48 hours post transfection with a majority of the 38 Ang-2 siRNA candidates tested (FIG. 8), including one siRNA which targets both human and mouse Ang-2.

Three Ang-2 siRNA, #10 (Ang-2-25-10), #14 (Ang-2-25-14), and #31 (Ang-2-25-31) were selected for further experiments as Ang-2 siRNA. In addition, #25 (Ang-2-25-25) and #45 (Ang-2-25-45) were selected for further experiments as human/mouse Ang-2 siRNA.

Determination of IC50 Values of Ang-2 siRNA

Upon the confirmation of Ang-2 siRNA candidates, experiments were conducted to determine the IC50 value of Ang-2 siRNA (Ang-2-25-10, Ang-2-25-14, and Ang-2-25-31) in HUVEC cells. Briefly, 10 dilutions of each siRNA duplex were spotted onto the bottom of a 96-well plate followed by addition of 0.25 μl of Lipofectamine™ RNAiMAX (Invitrogen). The siRNA dilutions were 0.076 pM, 0.31 pM, 1.2 pM, 4.9 pM, 19.5 pM, 78.1 pM, 312.5 pM, 1.25 nM, 5 nM, and 20 nM. The plate was incubated at room temperature for 10-20 minutes, and 7,500 HUVEC cells in 100 μl growth medium was added to each well. The plate was mixed gently by rocking the plate back and forth, and then incubated for 48 hours at 37° C. in a CO₂ incubator. The effect of siRNA-mediated Ang-2 knockdown was monitored by measuring the concentration of Ang-2 protein in the medium using a human Ang-2 ELISA kit (R&D). The cell viability of the transfected cells was measured using a WST-1 assay kit (Roche) for normalization of Ang-2 concentration.

The IC50 value of each siRNA duplex in HUVEC cells at 48 hours post siRNA transfection was obtained using the GraphPad Prism program (FIG. 9). The IC50 of Ang-2-25-10 was 0.363 nM, the IC50 of Ang-2-25-14 was 0.494 nM, and the IC50 of Ang-2-25-31 was 0.398 nM (FIG. 9 and Table 12).

Example 6

Determination of IC50 Values of Human/Mouse Ang-2 siRNA

Upon the confirmation of human/mouse Ang-2 siRNA candidates that target both human and mouse Ang-2 mRNA, experiments were conducted to determine the IC50 value of human/mouse Ang-2 siRNA (Ang-2-25-25 and Ang-2-25-45) in HUVEC cells. Briefly, 10 dilutions of each siRNA duplex were spotted onto the bottom of a 96-well plate followed by addition of 0.25 μl of Lipofectamine™ RNAiMAX (Invitrogen). The siRNA dilutions were 0.076 pM, 0.31 pM, 1.2 pM, 4.9 pM, 19.5 pM, 78.1 pM, 312.5 pM, 1.25 nM, 5 nM, and 20 nM. The plate was incubated at room temperature for 10-20 minutes, and 7,500 HUVEC cells in 100 μl growth medium was added to each well. The plate was mixed gently by rocking the plate back and forth, and then incubated for 48 hours at 37° C. in a CO₂ incubator. The effect of siRNA-mediated Ang-2 knockdown was monitored by measuring the concentration of Ang-2 protein in the medium using a human Ang-2 ELISA kit (R&D). The cell viability of the transfected cells was measured using a WST-1 assay kit (Roche) for normalization of Ang-2 concentration.

The IC50 value of each siRNA duplex in HUVEC cells at 48 hours post siRNA transfection was obtained using the GraphPad Prism program (FIG. 10). The IC50 of Ang-2-25-25 was 1.634 nM, and the IC50 of Ang-2-25-45 was 0.90 nM (FIG. 10 and Table 12).
