The present invention relates to pharmacodynamic (PD) markers inducible by interferon (IFN) alpha, probes and kits that detect the PD markers, and methods employing the same.
The present invention encompasses PD markers that are induced by IFNα. The PD markers can be used in methods of treating patients with a therapeutic agent that binds to and modulates IFNα activity, methods that identify patients as candidates for a therapeutic agent that binds to and modulates IFNα activity, methods of diagnosing a patient as having a disorder associated with increased IFNα levels, methods of monitoring disease progression of a patient receiving treatment with a therapeutic agent that binds to and modulates IFNα activity, and methods of identifying a candidate therapeutic for treating IFNα-mediated disorders
One embodiment of the invention encompasses a method of identifying a patient as a candidate for a therapeutic agent that binds to and modulates IFNα activity. Presence or absence of an IFNα-inducible PD marker expression profile is detected in a sample from the patient.
Another embodiment of the invention encompasses a method of treating a patient having a type I IFN or IFNα-mediated disease or disorder. An agent that binds to and modulates type I IFN or IFNα activity is administered to the patient. The agent neutralizes a type I IFN or IFNα-inducible PD marker expression profile of the patient.
Yet another embodiment of the invention encompasses a method of treating an autoimmune disease patient comprising a moderate or strong type I IFN or an IFNα PD marker profile. An agent that binds to and modulates type I IFN or IFNα activity is administered to the patient. The agent neutralizes the type I IFN or IFNα-inducible PD marker expression profile of the patient.
A further embodiment of the invention encompasses a method of neutralizing a type I IFN or IFNα-inducible PD marker expression profile in a patient in need thereof. An agent that binds to and modulates type I IFN or IFNα activity is administered to the patient. The agent neutralizes the type I IFN or IFNα-inducible PD marker expression profile of the patient.
Another embodiment of the invention encompasses a method of diagnosing a patient as having a disorder associated with increased IFNα levels. Presence or absence of an IFNα-inducible PD marker expression profile is detected in a sample from the patient.
A further embodiment of the invention encompasses a method of monitoring disease progression of a patient receiving treatment with a therapeutic agent that binds to and modulates IFNα activity. A first IFNα-inducible PD marker expression profile is obtained in a first sample from the patient. A therapeutic agent that binds to and modulates IFNα activity is administered to the patient. A second IFNα-inducible PD marker expression profile is obtained from a second sample from the patient. The first and the second IFNα-inducible PD marker expression profiles are compared.
Yet another embodiment of the invention encompasses a method of identifying a candidate therapeutic for treating IFNα-mediated disorders. Cells comprising an IFNα-inducible PD marker expression profile are contacted with an agent. Presence or absence of a change in the IFNα-induced PD marker expression profile of the cells is detected.
A further embodiment of the invention encompasses a set of probes.
Yet a further embodiment of the invention encompasses kits that comprise the probes.
Another embodiment of the invention encompasses a method of detecting IFN activity in a sample. Cells comprising a polynucleotide sequence comprising a reporter gene under the control of an IFN-stimulated response element are incubated with a sample. Expression of the reporter gene is detected.

Patients include any animal having a type I IFN or an IFNα-inducible disease, disorder, or condition. The patient may have the disease, disorder, or condition as a result of experimental research, e.g., it may be an experimental model developed for the disease, disorder, or condition.

The type I IFN or IFNα-inducible PD marker expression profile may be a strong profile, a moderate profile, or a weak profile. The type I IFN or IFNα-inducible PD marker expression profile can readily be designated as strong, moderate, or weak by determining the fold dysregulation of the type I IFN or IFNα-inducible PD marker expression profile of the patient, (e.g., the fold increase in expression of upregulated type I IFN or IFNα-inducible PD markers in the patient), relative to a control sample(s) or control patient(s) and comparing the patient's fold dysregulation to that of other patients having a type I IFN or IFNα-inducible PD marker expression profile.

These symptoms may include fatigue, organ damage, malar rash, and alopecia. The patient may be scored using a known clinical scoring system, e.g., SLEDAI which is an index of SLE disease activity as measured and evaluated within the last 10 days (Bombardier C, Gladman D D, Urowitz M B, Caron D, Chang C H and the Committee on Prognosis Studies in SLE: Derivation of the SLEDAI for Lupus Patients. Arthritis Rheum 35:630-640, 1992). Disease activity under the SLEDAI scoring system can range from 0 to 105. The following categories of SLEDAI activity have been defined: no activity (SLEDAI=0); mild activity (SLEDAI=1-5); moderate activity (SLEDAI=6-10); high activity (SLEDAI=11-19); very high activity (SLEDAI=20 or higher). (Griffiths, et al., Assessment of Patients with Systemic Lupus Erythematosus and the use of Lupus Disease Activity Indices). Another disease scoring index is the BILAG index which is an activity index of SLE that is based on specific clinical manifestations in eight organ systems: general, mucocutaneous, neurological, musculoskeletal, cardiovascular, respiratory, renal, and hematology results. Scoring is based on a letter system, but weighted numerical scores can also be assigned to each letter, making it possible to calculate a BILAG score in the range of 0-72. (Griffiths, et al., Assessment of Patients with Systemic Lupus Erythematosus and the use of Lupus Disease Activity Indices). Other scoring indices include the PGA score, the composite responder index (CRI), and the ANAM4™ test. The methods described herein, e.g., of treating an autoimmune disorder, may be used for any subject identified as having any activity level of disease activity as measured by any classification methodology known in the art, e.g., mild, moderate, high, or very high. The methods described herein, e.g., of treating an autoimmune disorder, may result in a decrease in a patient's symptoms or may result in an improvement in a score of disease for the patient's type I IFN or an IFNα-inducible disease, disorder, or condition.
A therapeutic agent may be administered to a patient or a patient may be identified as a candidate for administration of an agent or a therapeutic agent. A therapeutic agent is any molecule that binds to and modulates type I IFN or IFNα activity. The therapeutic agent may be a small molecule or a biological agent. If the therapeutic agent is a small molecule it may be synthesized or identified and isolated from a natural source.
If the therapeutic agent is a biological agent, it may be an antibody specific for any subtype(s) of type I IFN or IFNα. For instance, the antibody may be specific for any one of IFNα1, IFNα2, IFNα4, IFNα5, IFNα6, IFNα7, IFNα8, IFNα10, IFNα14, IFNα17, IFNα21, IFNβ, or IFNω. Alternatively, the antibody may be specific for any two, any three, any four, any five, any six, any seven, any eight, any nine, any ten, any eleven, any twelve type I IFN of IFNα subtypes. If the antibody is specific for more than one type I IFN subtype, the antibody may be specific for IFNα1, IFNα2, IFNα4, IFNα5, IFNα8, IFNα10, and IFNα21; or it may be specific for IFNα1, IFNα2, IFNα4, IFNα5, IFNα8, and IFNα10; or it may be specific for IFNα1, IFNα2, IFNα4, IFNα5, IFNα8, and IFNα21; or it may be specific for IFNα1, IFNα2, IFNα4, IFNα5, IFNα10, and IFNα21. Antibodies specific for type I IFN or IFNα include MEDI-545, any biologic or antibody other than MEDI-545, antibodies described in U.S. patent application Ser. No. 11/009,410 filed Dec. 10, 2004 which published as U.S. Patent Application Publication No. US20070014724 on Jan. 18, 2007 and issued as U.S. Pat. No. 7,741,449; and Ser. No. 11/157,494 filed Jun. 20, 2005 which published as U.S. Patent Application Publication No. US20060029601 on Feb. 9, 2006 and issued as U.S. Pat. No. 7,662,381, 9F3 and other antibodies described in U.S. Pat. No. 7,087,726 (Example 1 and Example 2, those disclosed in Table 3 and Table 4, and/or those disclosed in the table entitled “Deposit of Material” on lines 25-54, column 56), NK-2 and YOK5/19 (WO 84/03105), LO-22 (U.S. Pat. No. 4,902,618), 144 BS (U.S. Pat. No. 4,885,166), and EBI-1, EBI-2, and EBI-3 (EP 119476). A therapeutic agent that modulates IFNα activity may neutralize IFNα activity. One of skill in the art is well aware of preparation and formulation of such biological agents and methods of their administration.
The antibody may be a synthetic antibody, a monoclonal antibody, polyclonal antibodies, a recombinantly produced antibody, an intrabody, a multispecific antibody (including bi-specific antibodies), a human antibody, a humanized antibody, a chimeric antibody, a single-chain Fv (scFv) (including bi-specific scFv), a BiTE molecule, a single chain antibody, a Fab fragments, a F(ab′) fragment, a disulfide-linked Fv (sdFv), or an epitope-binding fragment of any of the above. The antibody may be any of an immunoglobulin molecule or immunologically active portion of an immunoglobulin molecule. Furthermore, the antibody may be of any isotype. For example, it may be any of isotypes IgG1, IgG2, IgG3 or IgG4. The antibody may be a full-length antibody comprising variable and constant regions, or an antigen-binding fragment thereof, such as a single chain antibody, or a Fab or Fab′2 fragment. The antibody may also be conjugated or linked to a therapeutic agent, such as a cytotoxin or a radioactive isotope.
In the methods of treatment a second agent other than the agent that binds to modulates IFNα activity may be administered to the patient. Second agents include, but are not limited to non-steroidal anti-inflammatory drugs such as ibuprofen, naproxen, sulindac, diclofenac, piroxicam, ketoprofen, diflunisal, nabumetone, etodolac, and oxaprozin, indomethacin; anti-malarial drugs such as hydroxychloroquine; corticosteroid hormones, such as prednisone, hydrocortisone, methylprednisolone, and dexamethasone; methotrexate; immunosuppressive agents, such as azathioprine and cyclophosphamide; and biologic agents that, e.g., target T cells such as Alefacept and Efalizumab, or target TNFα, such as, Enbrel, Remicade, and Humira.
Treatment with the agent may result in neutralization of the type I IFN or IFNα-inducible profile. Treatment with the agent may result in a decrease in one or more symptoms of the type I IFN or an IFNα-mediated disease or disorder. Treatment with the agent may result in fewer flare-ups related to the type I IFN or an IFNα-mediated disease or disorder. Treatment with the agent may result in improved prognosis for the patient having the type I IFN or an IFNα-mediated disease or disorder. Treatment with the agent may result in a higher quality of life for the patient. Treatment with the agent may alleviate the need to co-administer second agents or may lessen the dosage of administration of the second agent to the patient. Treatment with the agent may reduce the number of hospitalizations of the patient that are related to the type I IFN or an IFNα-mediated disease or disorder.

A candidate therapeutic for treating IFNα-mediated disorders may be identified by the methods encompassed by the invention. Candidate therapeutics may be any type of molecule including a small molecule or a biological agent. A candidate therapeutic identified by the methods encompassed by the invention may immediately be identified as useful as a therapeutic for a disease, disorder, or condition. Alternatively, a candidate therapeutic identified by the methods encompassed by the invention may need to be further tested and/or modified before selection for treating patients. Alternatively, a candidate therapeutic identified by the methods encompassed by the invention may, after further testing, be de-selected as a molecule for treating patients.

In methods of monitoring disease progression of a patient samples from the patient may be obtained before and after administration of an agent, e.g., an agent that binds to and modulates type I IFN or IFNα activity, or an agent that binds to and does not modulate type I IFN or IFNα activity, or a combination of agents that may or may not include an agent that binds to and modulates type I IFN or IFNα activity. Type I IFN or IFNα inducible PD marker expression profiles are obtained in the (before and after agent administration) samples. The type I IFN or IFNα inducible PD marker expression profiles in the samples are compared. Comparison may be of the number of type I IFN or IFNα inducible PD markers present in the samples or may be of the quantity of type I IFN or IFNα inducible PD markers present in the samples, or any combination thereof. Variance indicating efficacy of the therapeutic agent may be indicated if the number or level (or any combination thereof) of up-regulated type I IFN or IFNα inducible PD markers decreases in the sample obtained after administration of the therapeutic agent relative to the sample obtained before administration of the therapeutic agent. The number of up-regulated type I IFN or IFNα inducible PD markers may decrease by at least 1, at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, or at least 10.

The number of up-regulated type I IFN or IFNα inducible PD markers with decreased levels may be at least 1, at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 15, at least 20, at least 25, at least 30, or at least 35. Any combination of decreased number and decreased level of up-regulated type I IFN or IFNα inducible PD markers may indicate efficacy. Variance indicating efficacy of the therapeutic agent may be indicated if the number or level (or any combination thereof) of down-regulated type I IFN or IFNα inducible PD markers decreases in the sample obtained after administration of the therapeutic agent relative to the sample obtained before administration of the therapeutic agent. The number of down-regulated type I IFN or IFNα inducible PD markers may decrease by at least 1, at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, or at least 10. The level of any given down-regulated type I IFN or IFNα inducible PD marker may increase by at least 10%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, or at least 95%. The number of down-regulated type I IFN or IFNα inducible PD markers with increased levels may be at least 1, at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 15, at least 20, at least 25, at least 30, or at least 35. Any combination of decreased number and increased level of down-regulated type I IFN or IFNα inducible PD markers may indicate efficacy.
The sample obtained from the patient may be obtained prior to a first administration of the agent, i.e., the patient is naïve to the agent. Alternatively, the sample obtained from the patient may occur after administration of the agent in the course of treatment. For example, the agent may have been administered prior to the initiation of the monitoring protocol. Following administration of the agent an additional samples may be obtained from the patient and type I IFN or IFNα inducible PD markers in the samples are compared. The samples may be of the same or different type, e.g., each sample obtained may be a blood sample, or each sample obtained may be a serum sample. The type I IFN or IFNα inducible PD markers detected in each sample may be the same, may overlap substantially, or may be similar.
The samples may be obtained at any time before and after the administration of the therapeutic agent.

The invention also encompasses kits and probes. The probes may be any molecule that detects any expression or activity of any gene that may be included in an IFNα-inducible PD marker expression profile.
The invention also encompasses methods of detecting IFN activity. These methods may employ cells comprising a polynucleotide sequence comprising a reporter gene under the control of an interferon-stimulated response element. The cells comprising the polynucleotide sequence may be any cells amenable to transfection or transformation with a polynucleotide sequence and that can be maintained in culture. These cells include animal cells, bacterial cells, yeast cells, insect cells, or plant cells. These cells may be adherent or may grow in suspension. If the cells are animal cells, they may be from a known cell line such as HeLa, COS, NIH3T3, AGS, 293, CHO, Huh-7, HUVEC, MCF-7, C6, BHK-21, BNL CL 2, C2C12, HepG2, and ATDC5. Countless other cell lines are known and can be obtained by those of skill in the art. The cells may alternatively be primary cells that have or have not been immortalized.
The cells may comprise a polynucleotide sequence comprising a reporter gene under the control of an interferon-stimulated response element. The polynucleotide sequence may be stably integrated in the DNA of the cell or may be an extrachromosomal element that is stably or transiently in the cell. The polynucleotide may have been introduced to the cell as a naked polynucleotide molecule, a polynucleotide molecule complexed with lipids or other molecules, or a polynucleotide in a virus particle.
If the polynucleotide was introduced as a naked polynucleotide molecule, the polynucleotide may have been a linear or a circular molecule. Non-limiting examples of circular polynucleotide molecules include plasmids, and artificial chromosomes. These vectors may be cleaved with enzymes, for example, to generate linear polynucleotide molecules.
Furthermore, if the polynucleotide was introduced as a naked polynucleotide it may have been introduced into the cells by any of many well known techniques in the art. These techniques include, but are not limited to, electroporation, microinjection, and biolistic particle delivery. See, also, e.g., Loeffler and Behr, 1993, Meth. Enzymol. 217:599-618; Cohen et al., 1993, Meth. Enzymol. 217:618-644; Clin. Pharma. Ther. 29:69-92 (1985), Sambrook, et al. Molecular Cloning: A Laboratory Manual. 2nd, ed., Cold Spring Harbor Laboratory, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y., 1989 and Ausubel et al., ed. Current Protocols in Molecular Biology, John Wiley & Sons, Inc., N.Y., N.Y. (1987-2001).
If the polynucleotide was introduced as a complex with lipids or liposomes, it too may have been introduced by one of many known techniques to the skilled artisan. Lipids or liposomes comprise a mixture of fat particles or lipids which bind to DNA or RNA to provide a hydrophobic coated delivery vehicle. Suitable liposomes may comprise any of the conventional synthetic or natural phospholipid liposome materials including phospholipids from natural sources such as egg, plant or animal sources such as phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, sphingomyelin, phosphatidylserine or phosphatidylinositol. Synthetic phospholipids also may be used, e.g., dimyristoylphosphatidylcholine, dioleoylphosphatidylcholine, dioleoylphosphatidycholine and corresponding synthetic phosphatidylethanolamines and phosphatidylglycerols. Lipids or liposomes that may be conjugated with the vector are also commercially available to the skilled artisan. Examples of commercially available lipid or liposome transfection reagents known to those of skill in the art include LIPOFECTAMINE™ (Invitrogen), GENEJUICE® (Novagen), GENEJAMMER® (Stratagene), FUGENE® HD (Roche), MEGAFECTIN™ (Qbiogene), SUPERFECT® (Qiagen), and EFFECTENE® (Qiagen).
If the polynucleotide was introduced as a complex with other molecules it may have been compacted or in a nanosphere. Compacted polynucleotide complexes are described in U.S. Pat. Nos. 5,972,901, 6,008,336, and 6,077,835. Nanospheres are described in U.S. Pat. Nos. 5,718,905 and 6,207,195. These compacted polynucleotide complexes and nanospheres that complex nucleic acids utilize polymeric cations. Typical polymeric cations include gelatin, poly-L-lysine, and chitosan. Alternatively, the polynucleotide may have been complexed with DEAE-dextran, or transfected using techniques such as calcium phosphate coprecipitation, or calcium chloride coprecipitation.
If the polynucleotide was introduced associated with a virus, the virus may have been any well known suitable virus for polynucleotide delivery. Example viruses that may be used as vectors include adenovirus, adeno-associated virus, lentivirus, retrovirus, herpes virus (e.g. herpes simplex virus), vaccina virus, papovirus, Sendai virus, SV40 virus, respiratory syncytial virus, etc.
The polynucleotide sequence may include a reporter gene and an interferon-stimulated response element. The reporter gene may be any one of luciferase, chloramphenicol acetyl transferase, β-galactosidase, green fluorescent protein, β-glucuronidase, or secreted placental alkaline phosphatase. Variations of many of these reporter genes, e.g., green fluorescent protein and luceriferase, are known and can be readily identified and/or produced by those of skill in the art. Other reporter genes in addition to those listed will also be known to those of skill in the art and are readily available. Interferon-stimulated response elements are also known to those of skill in the art. They may be obtained from commercial vendors such as Stratagene, Clonetech, and Biomyx. They have also been reported in, for instance, Alcantara et al. (Nuc. Acid. Res. 30 (2002):2068-2075 and Kirchhoff et al. (Oncogene 18 (1999):3725-3736).
The cells employed in the assay may be incubated with a sample. The sample may be obtained from a patient, from a vendor with patient samples, or a control sample used for calibration or as a control. If the sample is obtained from a patient it may be any biological fluid or tissue, such as whole blood, saliva, urine, synovial fluid, bone marrow, cerebrospinal fluid, nasal secretions, sputum, amniotic fluid, bronchioalveolar lavage fluid, peripheral blood mononuclear cells, total white blood cells, lymph node cells, spleen cells, tonsil cells, or skin.
Expression of the reporter gene is detected by any well known means in the art. The expression, even if “0” indicates IFN activity in the sample. One of skill in the art may further quantitate any level of expression of the reporter gene which may then correlate to level of IFN activity in the sample.

Gene expression in whole blood of 5 (2 cutaneous and 3 severe) lupus patients and 5 healthy volunteers was profiled using Affymetrix whole genome array technology and qPCR validation. Gene expression fold-change values were determined by calculating the log2 signal intensity difference between individual lupus patient samples and the mean log2 signal intensity for the 5 healthy donor samples. 118 genes were identified as up-regulated by at least 2-fold in whole blood of all 5 lupus patients relative to the healthy volunteers.
Table 1 provides a summary for 71 of the 118 annotated genes identified as up-regulated by at least 2-fold in all 5 lupus patients. Table 2 provides the fold-up-regulation in gene expression for a subset of the 118 genes for each of the five lupus patients relative to the healthy volunteers. Table 2 also provides a comparison between fold-change values determined on two unique platforms (Affy GENECHIP microarray and TAQMAN (i.e. qPCR)).

To further identify candidate PD markers for anti-IFN-α mAb clinical trials in SLE, the Affymetrix Human Genome U133 Plus 2.0 GENECHIP® array platform was used to profile WB from 46 SLE patients and WB from 24 age- and sex-matched healthy donors. It was observed that 245 and 77 probe sets were upregulated and downregulated, respectively, in WB of SLE patients compared with that from healthy control donors.
Of the 245 probe sets upregulated in WB of SLE patients, 114 were type I IFN inducible. Table 30 lists the 50 most upregulated probe sets in WB of these SLE patients; 76% of them are type I IFN inducible. Table 30 also lists the prevalence of the overexpression of these genes in WB of SLE patients. The majority of these genes are overexpressed by at least 2-fold in 65% to 80% of the patients profiled. The robust and prevalent overexpression of a large number of type I IFN-inducible genes in SLE patients suggests that they might be suitable PD markers for clinical trials that investigate an anti-IFN-α mAb therapy for SLE.

In addition to the overexpression of a type I IFN gene signature, the overexpression of a gene signature that is indicative of granulocyte activation in WB of SLE patients was observed. The granulocyte gene signature included (but was not limited to) the following genes: AZU, DEFA1, DEFA4, ELA2, MMP8, MMP9, RNAS2, MPO, CAMP, FCAR, and CYBB (
The 50 most downregulated probe sets observed in WB of SLE patients are shown in Table 31. The downregulation of T, NK, and B cell gene signatures was observed in WB of SLE patients (
To further confirm the observation of overexpression of the type I IFN and granulocyte signatures and to identify other signaling pathways that may be altered in SLE, a pathway and network analysis was carried out with GENEGO software (see Methods). Overall, for SLE, this pathway analysis confirmed the activation of the type I IFN pathway, along with the activation of a granulocyte signature, and the underexpression of the T-cell signaling pathway. Additionally, in the patients profiled, the activation of the IL-10 signaling pathway was among the other notable pathways found to be altered. This may suggest B cell activation and be indicative of the abnormal apoptosis of T-cell subsets observed in SLE patients. (Diaz-Alderete A, Crispin J C, Vargas-Rojas M I and Alcocer-Varela J: IL-10 production in B cells is confined to CD154+ cells in patients with systemic lupus erythematosus. J. Autoimmun. 23(4), 379-383 (2004), Wang H, Xu J, Ji X et al.: The abnormal apoptosis of T cell subsets and possible involvement of IL-10 in systemic lupus erythematosus. Cell Immunol. 235(2), 117-121 (2005)).
Confirmation of Overexpression of Type I IFN-Inducible Genes:
To confirm the overexpression of type I IFN-inducible genes in SLE that were observed in the microarray analyses, a BIOMARK™ 48.48 dynamic array was used to perform high throughput (HTP) TAQMAN QRT-PCR on 40 of the type I IFN-inducible genes (selected based on their magnitude and prevalence of overexpression in whole blood of SLE patients). TAQMAN QRT-PCR assays confirmed the overexpression of all 40 genes in whole blood of 35 of the originally profiled 46 SLE patients. The overexpression of 15 of the 40 type I IFN-inducible genes using TAQMAN QRT-PCR assays is shown in
Using the whole genome profiling data described in Example 1a, a group of candidate PD markers were selected. These candidate markers are provided in Table 3.
qPCR was conducted for a selected group of candidate PD markers to determine whether they exhibited variation at baseline in the whole blood of healthy volunteers. qPCR indicated that baseline variation was minimal. See Table 4, which provides the baseline qPCR data (healthy volunteers shown in shaded columns).
A study was performed to determine whether IFNα could stimulate expression of candidate PD markers in whole blood of healthy volunteers. Whole blood of healthy volunteers was collected in heparinized tubes, transferred to the appropriate wells of 6-well culture plates, and incubated with leukocyte IFN doses of 3, 30, 100, and 300 I.U. and then incubated for 4 hours at 37° C., 5% CO2. Fold-induction of expression of candidate PD markers for genes IFI44, IRF2, RSAD2, G1P3, and HERC5 was determined using RNA isolated from PBMCs (Peripheral Blood Mononuclear Cells) with Qiagen's RNAeasy kit. As shown in Table 5 (IFI44 and IRF2), Table 6 (RSAD2), and Table 7 (G1P3 and HERC5) leukocyte IFN causes up-regulation in expression of each of these candidate PD markers. See also
A summary hierarchical clustering of all samples using 1384 genes differentially regulated by IFN type 1, IFN type 2, or TNFα obtained from a separate experiment is shown in
Because IFNα treatment of healthy volunteers' whole blood induced expression of candidate PD markers, it was determined whether IFNα Ab, MEDI-545, could neutralize the induction of expression of these markers.
Blood was drawn from each of three donors into heparin tubes. Aliquots of 2.5 ml of drawn blood were added to each of 4 wells of 6- or 24-well treatment plates. The 4 wells were designated for treatment as follows: (a) blood+vehicle, (b) blood+100 IU IFNα2a, (c) blood+100 IU IFNα2a+MEDI-545 (IFNα Ab), and (d) blood+100 IU IFNα2a+R347 (control Ab).
Wells containing blood to be treated with Ab were first incubated with either MEDI-545 (IFNα Ab; well (c)) or R347 (control Ab; well (d)) for 30 minutes. Following Ab treatment, vehicle (well (a)) or IFN α2a (wells (b), (c), and (d)) was added to the appropriate wells and was then incubated for an additional 4 hours at 37° C., 5% CO2. The samples were then transferred to PAXgene tubes and incubated at room temperature for 2 hr. Following the 2 hr incubation the tubes were transferred to −80° C. for storage.
Following, at least, an overnight incubation at −80° C. the total RNA of the cells was prepared according to the PAXgene protocol. First and second strand cDNA was prepared via Affy GRP methods and TAQMAN was conducted on the cDNA samples.
Expression of at least 11 candidate PD markers, previously identified as up-regulated in lupus patients, could be neutralized by MEDI-545 in the IFNα2a-stimulated whole blood. See Table 8 (RAB8B), Table 9 (IRF7), Table 10 (MARCKS), Table 11 (IL6ST), Table 12 (LY6E), Table 13 (IFIT3), Table 14 (IFIT1), Table 15 (HERC5), Table 16 (OAS1), Table 17 (OAS3), and Table 18 (RSAD2), which provide quantitative gene expression analysis for each of these 11 genes in the whole blood of each of the 3 healthy volunteers.

(a) Neutralization of type I IFN-induced genes by MEDI-545 could also be observed in whole blood of healthy volunteers that had been stimulated with serum obtained from lupus patients. Serum samples were obtained from SLE patients that had been tested in an IFN bioassay. Whole blood was collected from healthy donors in heparinized vacutainer tubes and PBMC were isolated using Ficoll gradient centrifugation method. PBMC were resuspended at 1×107 cells/mL in RPMI media with 10% fetal bovine serum (FBS) and 125 μL of cells were aliquoted into each well of a 24 well flat bottom plate (1.25×106 cells/well). Serum from SLE patients was preincubated for one hour with MEDI-545 (0.1, 1, 10 μg/mL), anti-IFN-γ antibody (1 μg/mL) or control antibody (10 μg/mL). SLE serum was added to the PBMC at a final concentration 25% (62.5 μL per well). Additional volume of RPMI+10% FBS was added to the wells to obtain a final volume of 250 μL per well. Plates were incubated at 37° C. for either 4 or 18 hours. Following the incubation, RNA was harvested by adding 750 μL of Trizol LS to each well. Samples were frozen at −70° C. until the time of RNA isolation. Table 21 provides the MEDI-545 blockade of 74 type I IFN genes in healthy volunteers' whole blood stimulated ex vivo with SLE patient serum.
Analysis of the genes uniquely activated at the 18 hour time point revealed upregulation of genes involved in the innate immune response (TLR, NFκB), adaptive immune response (NFAT, IL-1/IL-6), complement activation as well as leukocyte chemotaxis and adhesion. It is possible that neutralization of the type IFN pathway has the potential to modify downstream pathways that may significantly impact the pathogenesis of SLE.
Heatmap analysis was also performed to examine induction of a type I IFN signature in PBMCs of a healthy donor by serum of an SLE patient and neutralization of the type I IFN signature by MEDI-545. See
(b) Further investigation was conducted to identify early and late transcriptional responses in healthy donor PBMCs stimulated with SLE patient serum. In this study, four SLE patient serum samples, with varying levels of IFNα activity, were used to stimulate PBMCs isolated from a healthy donor. The varying levels of IFNα activity in the four SLE serum samples were determined in a luciferase reporter gene assay as described in Example 20. Briefly, HEK293H cells were stably transfected with a luciferase construct (Gaussia princeps) under the control of the IFN-stimulated response element (ISRE). Transfected cells were incubated with 50% patient sera and luciferase activity was detected in the culture supernatants 24 h later. Samples generating a signal greater than 1.5× negative control wells (normal human serum) were considered positive. To determine which class of type I IFN was responsible for the positive response, cells were treated with anti-type I and anti-type II IFN mAbs.
Each of the four SLE patient serum samples was co-incubated with PBMCs isolated from a healthy volunteer. The PBMCs from the healthy volunteer (previously determined to be IFN-signature negative) were isolated using Ficoll gradient centrifugation. Isolated PBMCs were incubated with 25% SLE patient serum or with 25% autologous patient serum (as a negative control). Following the incubation, cells were harvested with Trizol LS and stored at −70° C. for RNA isolation. Total RNA was extracted and RNA purity and concentration were determined spectrophotometrically (260/280>1.9). The generation and hybridization of biotin-labeled amplified complementary RNA (cRNA) were conducted according to manufacturer's instructions (Affymetrix, Santa Clara, Calif.). Data was generated by implementing a 3-fold (up-regulation) expression cutoff between SLE serum stimulation compared to autologous serum control samples (q value≦0.05).
The role of type I IFNs in inducing the 3-fold or more upregulation of probes by the SLE patient serum samples was next investigated. PBMCs isolated from a healthy volunteer, discussed above, were incubated with 25% SLE patient serum in the presence or absence of neutralizing antibodies against IFN-α, or irrelevant mAb, for 4 or 18 hours. As a negative control, PBMC were incubated with 25% of autologous patient serum. Following the incubation, cells were harvested with Trizol LS and stored at −70° C. for RNA isolation. Total RNA was extracted and RNA purity and concentration were determined spectrophotometrically (260/280>1.9). The generation and hybridization of biotin-labeled amplified complementary RNA (cRNA) were conducted according to manufacturer's instructions (Affymetrix, Santa Clara, Calif.). ARRAYASSIST® Lite software was used to calculate probe-level summaries from the array cell intensity files and R packages were used to identify differentially regulated genes (3-fold or greater upregulation in expression between SLE serum stimulation compared to autologous serum control samples (q value≦0.05); R Development Core Team, New Zealand). Percent neutralization was then determined by calculating the percent change for each upregulated probe treated with and without anti-IFNα antibody.
Genes, whether type I IFN genes or non-type I IFN genes, that were both upregulated and neutralized by anti-IFNα treatment at 18 hours, but that were not upregulated at 4 hours (i.e., “unique genes”) were identified for each SLE patient serum sample.
Cell pathways and processes neutralized by anti-IFNα treatment at the 18 hr time point are involved in cytokine and chemokine signaling pathways, immune regulation, cell adhesion, and cell survival. See
Whole blood of lupus patients receiving placebo, 0.3 mg/kg, 1.0 mg/kg, and 3.0 mg/kg MEDI-545 were analyzed for expression of IFNα-inducible PD markers over the course of 28 days. Whole blood (˜2.5 mL) was drawn into PAXgene RNA tubes and processed as outlined above. With increasing doses of MEDI-545, up-regulated expression of the top 25 PD markers was neutralized. See

Table 22 provides a list of the 63 type I IFN inducible probes upregulated in whole blood of lupus patients and neutralized by MEDI-545 or placebo by at least 30% at day 7, day 14, or day 28 post administration. Each set of columns provides neutralization data for each of the indicated genes at 7, 14, and 28 days post-administration. The first set of columns provides percentage neutralization of each of the indicated genes for lupus patients having a type I IFN signature and that were treated with MEDI-545. It can be noted that for each of the indicated genes, neutralization ranged from 30% to 68% at day 7 post-administration. Meanwhile, at day 7 in the placebo treated group, neutralization of the same genes ranged from 0% to 27%.

Table 33 provides the results of a separate study which determined the top 50 genes neutralized in SLE patient whole blood 7 days after MEDI-545 treatment. Only three genes of the 50 genes, ZCCHC2, REC8L1, and GCLM, were not IFN-α/β-inducible.
Using 169 probe sets to detect expression of a number of PD markers, gene expression in whole blood samples of 35 lupus patients was analyzed using PCA (Principal Component Analysis). Principal component analysis is a statistical technique for simplifying a dataset, by reducing multidimensional datasets to lower dimensions for analysis. PCA was conducted on the filtered data set (169 probe sets) using the Spotfire statistical tool. The PCA determined that 24/35 of the lupus patients had a statistically significant PD marker signature. See
Similarly, using 25 highly upregulated IFN-inducible genes, expression in whole blood samples of lupus patients and normal healthy donors was analyzed using PCA (Principal Component Analysis). The PCA determined that approximately 66% of the lupus patients had a strong/moderate type I IFN inducible signature. See
The overexpression of type I IFN genes in SLE patient whole blood for a larger number of patients, determined using an Affymetrix whole genome array, is provided in Table 23. Table 23 and

Based on the observations of different overexpressed type I IFN genes in SLE patients, described above, a set of 21 type I IFN genes in whole blood of lupus patients was identified as potentially useful. See Table 24.
Overexpression of these genes, as detected initially using the Affymetrix arrays, was confirmed by FLUIDIGM dynamic array, validating their overexpression. See
Patients in a clinical trial were identified as having a strong/moderate type I IFN gene, a weak type I IFN gene signature, or no type I IFN gene signature. These patients were designated into one of these groups based on 149 genes. Table 25 shows the number of lupus patients in the clinical trial that were designated in each of these three groups and indicates the treatment protocol they received.
The SLE patients that were designated as having strong and moderate type-I IFN gene signatures all had: an average 4-fold increase in expression of the top 25 most upregulated type I IFN genes; an average 2-fold increase in expression of the top 50 most upregulated type I IFN genes; and a percentage of total examined disease genes being type I IFN inducible of 3.8. The average fold increase in the top 25 type I IFN inducible genes for each patient having a strong/moderate type I IFN signature or a weak signature in the trial is provided in
Treatment of these different SLE patient groups provided evidence that neutralization of the type I IFN gene signature by MEDI-545 is drug specific.
Further break down of SLE patients into strong, moderate, and weak type-I IFN gene signatures was conducted. Briefly, the 25 most highly overexpressed type I IFN-inducible genes in individual SLE patients generated from the ex vivo stimulation of healthy donor WB with SLE patient sera study were selected and the median fold change of these 25 genes was used to construct a type I IFN gene signature score for each SLE patient.
To select a small, robust panel of type I IFN-inducible genes that could be developed into an HTP assay, the gene panel was narrowed to 21 genes. To identify the 21 potential PD and diagnostic markers, 807 IFN-α/β-inducible probes identified by ex vivo stimulation of healthy donor WB with 10 IFN-α subtypes (2a, 4b, 5, 6, 7, 8, 10, 14, 16, and 17) and IFN-β were used as a candidate marker starting point. The WB samples from a total of 46 SLE patients procured from commercial vendors and 24 healthy normal controls were used to determine the type I IFN-inducible probes that are upregulated in WB of SLE patients. 114 overexpressed probes (q≧0.05; fold change≧2) were identified in WB of SLE patients were type I IFN-inducible using SAM and FDR.
To investigate whether these overexpressed type I IFN-inducible genes in WB of SLE patients were neutralizable by an anti-IFN-α mAb, one healthy donor PBMC was stimulated ex vivo with sera from six individual SLE patients. The healthy donor was prescreened to exclude those donors that might have viral infection. 161 type I IFN-inducible probes were upregulated by ≧2-fold in the PBMC of the healthy donor following stimulation with ≧1 SLE patient serum in which the overexpression of these genes was suppressed by ≧50% and ≧70% by an anti-IFN-α mAb and an anti-IFN-α R mAb, respectively.
The intersection between this list of 161 probes and previously determined list of 114 probes was 80 probes. Each of these 80 probes was ranked by both the average fold change magnitude across all SLE patients and the percentage of patients displaying a change≧2-fold. Generally, the 21 most prevalently overexpressed type I IFN-inducible genes (that represent unique genes using the NetAffx annotation file for the Affymetrix U133 2.0 plus array; ESTs were excluded) from this ranking were retained for a static list of probes used to measure PD. The type I IFN signature score was then defined by the median of these 21 genes.
With these 21 genes, it was necessary to recalculate the thresholds that had been previously identified for partitioning SLE patients into type I IFN gene signature responses of strong, moderate, or weak (based on the Affymetrix platform) for a lower density platform (TAQMAN-based assay). A scaling method was required to convert the type I IFN signature score based on the top 25 differentially expressed genes (independent for each SLE patient) on the Affymetrix platform to the type I IFN signature score based on the 21 genes selected for the TAQMAN-based assay. This method was implemented to compensate for 3 primary differences between the 2 platforms: (1) the number of probes used for the type I IFN signature (25 genes dynamically determined for each patient on the Affymetrix platform versus a 21 static gene list on the TAQMAN-based assay), (2) the differences in sensitivity between the 2 platforms, and (3) the scales of the dynamic ranges within each platform. First, the fold change values were calculated (on a log2 scale) for the 155 type I-inducible probes between the 35 randomly selected SLE patients and the average of a set of normal healthy controls. The genes with the top 25-fold change values were determined for each patient on the Affymetrix platform (this gene set is allowed to vary from patient to patient depending on which type I IFN-inducible genes are most highly expressed). Next, the median fold change was calculated from the top 25 genes for each SLE patient. The same calculation was conducted across the same patients using the static 21 gene set on the TAQMAN-based assay. This gene set was identical for each patient and the median fold change was calculated based on 21 genes, rather than 25 dynamic genes, as was conducted for the Affymetrix platform. A simple regression model was then computed using these 2 vectors of equal length (35 median fold change values), and the coefficients from the model were used to calculate the conversion factor (from the Affymetrix platform to the TAQMAN-based assay) for the response threshold values to partition the SLE patients into a type I IFN gene signature category of strong (>10 on Affymetrix; >5.53 on TAQMAN), moderate (between 4 and 10 on Affymetrix; between 1.91 and 5.53 on TAQMAN), or weak (<4 on Affymetrix; <1.91 on TAQMAN). Using these scaled threshold values, for the purpose of stratifying SLE patients, the signature (ie, median fold change) that was calculated on the 21 genes from the TAQMAN-based assay was comparable to that from the top 25 upregulated type I IFN-inducible genes.
The prevalence and fold change (log2 based) of the 21 IFN α/β-inducible genes in whole blood of 111 SLE patients is provided in Table 32, below.
These 21 genes were neutralized in a dose-dependent dependent fashion by MEDI-545. See
To identify the type-I IFN subtypes responsible for the induction of the type-I IFN signature of SLE patients, mRNA levels of type-I IFN genes in SLE patient whole blood were measured.
Gene expression analysis was performed using a TAQMAN Low Density Array (TLDA) from Applied Biosystems. Expression of type-I IFNα subtypes 1, 2, 5, 6, 7, 8, 14, 17, and 21 was monitored and compared in whole blood of SLE patients relative to healthy volunteers.
Double-stranded cDNA for each patient sample was pre-amplified using the TAQMAN PreAmp Master Mix kit (Applied Biosystems). cDNA was pre-amplified by conducting 10 cycles of PCR on each patient sample using a pooled solution of primers, a pair for each gene analyzed on the array. The pre-amplified cDNA were diluted 1:5 with TE. A 50 μL volume of the diluted pre-amplified cDNA was added to a 50 μL volume of 2× TAQMAN Universal PCR Master Mix (Applied Biosystems) and mixed. The array was loaded with the mixture using standard procedures and the loaded array was run on a 7900HT Fast Real-Time PCR System (Applied Biosystems). Data analysis of the resulting Ct values was conducted with the SDSv2.2.2 software tool (Applied Biosystems).
To identify type-I IFN inducible genes over-expressed in keratinocytes of lesions of psoriatic patients, whole blood and keratinocytes of healthy donors were stimulated ex vivo with a panel of IFNα subtypes, as well as IFNβ, IFNγ, and TNFα.
Whole blood was collected from healthy donors in heparinized tubes. The total blood volume collected from each donor was pooled into a single culture flask and 3 mL of the total volume was aliquoted into a single well of a 6-well culture plate. Individual wells of blood were then exposed to a variety of treatments, including: vehicle (1×PBS), a panel of IFNα subtypes (IFNα2a, -4b, -5, -6, -7, -8, -10, -16, -17), IFNβ, IFNω, IFNλ, IFNγ, leukocyte IFN, or TNFα. Following exposure, the blood was gently mixed by pipetting and incubated at 37° C., 5% CO2 for 4 hrs (TNFα treatment was conducted for both 2 hrs and 4 hrs). Following the incubation period, 2.5 mL of blood was transferred to a PAXgene RNA tube and inverted 8-10 times. The PAXgene tubes were incubated at room temperature for two hours and then frozen (−20° C. overnight, -70° C. for long term storage) until further processing was required. Induction of gene expression by exposure to each of the treatment conditions was performed using Affymetrix GENECHIP® human genome U133 plus v2.0 arrays.
The various IFNα subtypes and IFNβ up-regulated 900-1200 probe sets by at least 2 fold. Of these, 689 probe sets (approximately 1.3% of all probe sets on the Affymetrix human genome U133 plus v2.0 array) were uniformly up-regulated by at least 2 fold in all donors by all ten IFNα subtypes and IFNβ. Using the same approach, 336 probe sets were identified as down-regulated by IFNα/β in the ex vivo stimulated whole blood.
Alterations in gene expression in healthy patient whole blood stimulated with TNFα were also observed at both the two and four hour time points. In all, 234 and 72 probe sets were up-regulated and down-regulated, respectively, by at least 2 fold in all donors. Furthermore, IFNγ challenge of whole blood for 4 hrs induced up-regulation of 304 probe sets and down-regulation of 52 probe sets by at least 2 fold. Little overlap was observed in the probe sets up-regulated by IFNα/β and TNFα (40 probes). By contrast, greater overlap was observed in the probe sets up-regulated by IFNα/β and IFNγ. 198 probes were up-regulated by at least 2-fold by both IFNα/β and IFNγ. Of the 198 probes up-regulated by at least 2-fold by both IFNα/β and IFNγ, the magnitude of up-regulation by IFNα/β was greater for about ⅔ of these probes (p value less than 0.05) than IFNγ.
a provides the hierarchical clustering of the relative expression of only the top 25 type-I IFN inducible probe sets identified in the ex vivo stimulated whole blood.
Normal human keratinocytes (EpiDerm system, MatTek, Inc.) were grown under serum-free conditions according to the manufacturers instructions. Briefly, keratinocytes were maintained on tissue culture inserts at the air-liquid interface to maintain a multilayered, fully differentiated epithelial phenotype. Keratinocytes were stimulated with human leukocyte IFN (15, 50, 150, IU/mL, PBL Biomedical Labs), human IFNα2a (15-350 IU/ml, PBL Biomedical Labs), recombinant human TNFα, (0.1 ng/ml, R+D Systems) or recombinant human IFNγ (3 ng/ml, R+D Systems). Epidermal cultures were harvested at 2, 4, or 18 hours post treatment for transcript analysis. Over 100 probe sets were identified as overexpressed in keratinocytes cultures stimulated with human IFNα2a and leukocyte IFN.
b provides the hierarchical clustering of the relative expression of 25 type-I IFN inducible genes in ex vivo stimulated keratinocytes. The 25 type-I IFN inducible probe sets used to prepare the hierarchical clustering are the top 25 type-I IFN inducible probes identified in the ex vivo stimulated whole blood (those shown in
In addition, many of these genes were among those most overexpressed in the lesional skin of psoriasis patients. See discussion in Example 11, below.
A comparison of gene expression profiles of skin samples from healthy donors and paired non-lesional/lesional skin samples from psoriasis patients was performed to identify a type-I interferon induced gene expression signature associated with psoriatic skin lesions. Briefly, skin samples of 21 normal healthy control donors (5 samples obtained from Biochain, 14 from ILSbio, and 2 from Dr. James Krueger's lab) and 26 paired non-lesional/lesional skin samples of 24 psoriatic patients (21 pairs obtained from Asterand, and 5 from Dr. James Krueger's lab) were obtained. Three additional lesional skin samples from 3 psoriatic patients were obtained. These 3 additional lesional skin samples lacked a paired non-lesional skin sample because the non-lesional skin sample either did not yield sufficient cRNA for hybridization or the scanned array for the non-lesional skin sample had high scaling factors that were more than 3-fold of average.
Total RNA from the samples was extracted using the Qiagen RNAeasy-Mini kit (Hilden, Germany). The purity and concentration of the extracted RNA were determined spectrophotometrically (260/280>1.9). RNA quality was assessed on an Agilent 2100 Bioanalyzer using the RNA 6000 NANO LABCHIP®. Generation of biotin-labeled amplified cRNA, from 2 μg of total RNA, was accomplished using the Affymetrix GENECHIP® One-Cycle cDNA Synthesis kit and the AFFYMETRIX GENECHIP® WT Labeling kit. Concentration and purity of the cRNA product were determined spectrophotometrically.
Twenty micrograms of each biotin-labeled cRNA was fragmented for hybridization on Affymetrix GENECHIP® human genome U133 plus v2.0 arrays. Fragmented cRNA was prepared for hybridization as outlined in the Affymetrix GENECHIP® manual. Hybridization was conducted overnight in a model 320 rotating hybridization oven set at 45° C. All GENECHIP® wash and staining procedures were performed on an Affymetrix Model 450 Fluidics station. Arrays were scanned on an Affymetrix GENECHIP® Scanner 3000. Data capture and initial array quality assessment were performed with the GENECHIP Operating Software (GCOS) tool.
Stratagene's (La Jolla, Calif.) ARRAYASSIST® Lite software was used to calculate probe-level summaries (GC-RMA normalization algorithm) from the array CEL files. R packages (R development core team) samr & qvalue were used to generate differentially regulated genes. PCA and hierarchical clustering analyses were performed in both SpotFire and R(R Development Core Team). SAM & FDR were used to select differentially regulated genes (pairwise comparison between lesional and non-lesional skin, lesional and normal skin, and non-lesional and normal skin). Probe sets with a fold-change of at least 2 and q value less than or equal to 0.05 were considered to be differentially regulated. PCA and hierarchical clustering were performed in both SpotFire and bioconductor R.
Overall, 1408 probe sets were up-regulated and 1465 probe sets were down-regulated in lesional skin compared to non-lesional skin. Although the downregulated genes outnumbered the upregulated genes in the lesional skin, the magnitude of differential regulation of the upregulated genes was much greater as a whole. For example, 318 probe sets were upregulated by at least four fold in the lesional skin, while only 84 probe sets were downregulated by at least four fold in the lesional skin. Among them, 96 probe sets were upregulated by at least eight fold in the lesional skin, while only six probe sets were downregulated by at least eight fold.
463 probe sets were also up-regulated and 489 probe sets were down-regulated in non-lesional skin compared to normal skin.
To identify the most statistically significant signaling pathways altered in psoriasis, the list of differentially regulated genes were submitted to GENEGO for pathway and network analysis. Briefly, the pathway and network analysis was conducted with the MetaCore™integrated software suite from GENEGO, Inc. (St. Joseph, Mich.). The significance, given a particular pathway or network, is approximated by a hypergeometric distribution where the p-value essentially represents the probability of a particular gene set mapping arising by chance, given the numbers of genes in the set of all genes on pathway maps, genes on a particular pathway map and genes in the experiment.
Fifty seven signaling pathways were significantly altered in lesional skin compared to non-lesional skin, a majority of which were involved in immune response and cell cycle. The IFNα/β signaling pathway was the most significantly altered in lesional skin with a p value of 3.8×10−13. IFNα/β signaling pathway members such as IFNα, IFNβ, IFNAR1, IFNAR2, STAT1, IRF1, MPL, ISG15, IFI6 were all significantly overexpressed in lesional skin compared to uninvolved skin.
Overall, 22 signaling pathways were activated and 37 signaling pathways were inhibited (p<0.05) in the lesional skin compared to non-lesional skin. All the putative signaling pathways activated were either cytokine and chemokine mediated signaling pathways or were involved in immune responses. For example, IFNγ, TNFα and onconstatin M signaling pathways were activated in the lesional skin of psoriatic patients. Of all the signaling pathways altered in lesional and non-lesional skin, IFNα/β signaling pathway topped the list with a p value of 6.6×10−26 (
Using the list of probe sets identified to be type-I IFN inducible in the whole blood and keratinocyte ex vivo stimulation studies (Example 10), 164 of the 1408 (approximately 11.7%) probe sets upregulated in lesional relative to non-lesional skin were identified as type-I IFN inducible. Fisher's exact test calculated a p value (one-tailed t test) less than 0.0001, suggesting that the observed overexpression of type-I IFN genes in lesional skin of psoriatic patients was statistically significant. The type-I IFN induced genes were also many of the most highly upregulated genes in the lesional relative to non-lesional psoriatic skin. Nineteen percent of the top 100 and 200 most upregulated probe sets in lesional skin relative to non-lesional skin were type-I IFN genes. See
Table 26 lists, in descending order, the top 50 IFN induced probes in lesional skin compared to non-lesional skin of psoriasis patients. Table 26 not only compares the log 2-based fold change (log 2 fc) and q value for each of the 50 most upregulated type I IFN inducible genes in lesional relative to non-lesional skin of psoriasis patients, it also compares the log 2-based fold change and q value for these 50 genes in non-lesional skin of psoriasis patients relative to healthy control patients.
Removal of ESTs, hypothetical proteins, and duplications of genes due to identification by multiple probe sets produced Table 27. Table 27 provides, in descending order, the top 50 most upregulated type-I IFN genes in lesional skin compared to non-lesional skin. For genes identified by more than one probe set, only the probe set detected as most upregulated is provided.
The fold changes (log 2 fc) were calculated based on relative transcript level between paired lesional skin and non-lesional skin. Q values were calculated based on FDR. Prevalence tabulated the percentage of the 26 paired lesional and non-lesional skin that had at least 2-fold overexpression of the genes listed in the table.
These top 50 type-I IFN induced genes in lesional relative to non-lesional skin in psoriasis patients were overexpressed, on average, 3.2-fold (CCL2 and BLNK) to 24-fold (HPSE) more in the lesional skin. In addition, all of the genes in the table, except CCL2 and AIM2, were upregulated in at least 84% of the paired lesional/non-lesional skin biopsies (23 of the 26 pairs) of the psoriasis patients. This robust upregulation of a large panel of type-I IFN genes across lesional versus non-lesional skin samples of psoriasis patients provided a strong rationale for their use as PD markers.
As briefly alluded to, above, upregulation of type-I interferon inducible genes was consistently observed across psoriasis patients. Table 28 provides the average and median fold change of the top 25 most upregulated type-I IFN probe sets for each paired lesional/non-lesional skin sample. The top 25 most upregulated type-I IFN probe sets were consistently observed to detect elevated gene expression in the lesional relative to non-lesional skin of each individual psoriasis patient.
Seventeen probe sets were also observed as underexpressed in lesional skin that were also down-regulated by IFNα/β in the ex vivo stimulation studies described in Example 10. These genes include CYP1B1, TGST1, RRAGD, IRS2, MGST1, TGFBR3, and RGS2.
Although the array data obtained in Example 11 identified overexpression of numerous type-I IFN-inducible genes in lesional relative to non-lesional skin, it identified only 5 probe sets overexpressed in non-lesional skin relative to normal control skin. The p value of Fisher's exact test (two-tailed t-test) was 0.581, which suggested that the overexpression of the type-I IFN genes is not statistically significant in the non-lesional skin of the psoriasis patients over normal skin.
As shown in Table 26 (Example 11), most of the genes identified as being top 50 type-I IFN-induced genes in lesional relative to non-lesional skin were comparably expressed in non-lesional skin relative to normal skin controls (several genes, e.g., RGS1, SPTLC2, are downregulated in the non-lesional skin compared to normal skin).
Analysis of normal healthy, lesional psoriasis, and non-lesional psoriasis skin samples using the 164 probe sets identified in Example 11 as type-I IFN inducible, showed a clustering of lesional psoriasis samples and a clustering of non-lesional psoriasis and normal healthy skin samples.
These observations were further confirmed by gene pathway analysis. GENEGO analysis showed that the possibility of an alteration in the IFNα/β signaling pathway of non-lesional skin of psoriasis patients relative to normal skin had a p value close to 1. A distinctive separation of lesional skin samples from non-lesional skin samples and normal skin samples was even observed when clustering samples based on the transcript profile of an entire genome array. See
A BIOMARK™ 48.48 dynamic array (TAQMAN-based assay) from FLUIDIGM was used to validate the results of the Affymetrix GENECHIP® human genome U133 plus v2.0 arrays, results indicating that type-I IFN genes are up-regulated in lesional psoriatic relative to non-lesional psoriatic or normal skin samples.
Eighteen pairs of lesional and non-lesional skin samples from 18 psoriasis patients were used for the gene expression analysis. Twenty nine of these genes were type-I IFN inducible genes while 11 were highly upregulated in lesional skin but were not IFN-inducible genes, e.g., S100A9, S100A12, SERPINGB4, and KLK13. Each of these genes was selected based on prevalence and significance of overexpression in lesional skin. The overexpression of all genes in the lesional skin was confirmed by TAQMAN qRT-PCR, the majority of which showed very good correlation between microarray and TAQMAN assays.
Overall, the TAQMAN-based assay and Affymetrix array results correlated well, validating the selected genes as overexpressed type-I IFN-induced genes in lesional psoriatic skin. The distribution of correlation coefficients between the TAQMAN-based assay and the Affymetrix array for the 40 overexpressed genes is provided in
a-37d and 38 provide detailed gene expression data obtained from the microarray and TAQMAN-based assays for several type-I IFN-inducible genes in the paired lesional/non-lesional samples. These data evidence that similar levels of overexpression of type-I IFN-induced genes in lesional psoriatic skin is detected between the TAQMAN and array assays, and thus the high correlation coefficients discussed above.
Keratinocytes of healthy volunteers were isolated and stimulated ex vivo with escalating doses of IFNα2a and leukocyte IFN to induce an escalating type I IFNα-induced gene expression pattern. Anti-IFNα antibody was able to neutralize the type I IFNα-induced gene expression pattern in a dose-dependent manner.
Normal human keratinocytes (EpiDerm system, MatTek, Inc.) were grown under serum-free conditions according to manufacturer's instructions. Briefly, keratinocytes were maintained on tissue culture inserts at the air-liquid interface to maintain a multilayered, fully differentiated epithelial phenotype. Keratinocytes were stimulated with human leukocyte IFN (15-150 IU/ml, PBL Biomedical Labs) and human IFNα2a (15-350 IU/ml, PBL Biomedical Labs). In some wells a humanized anti-human IFNα monoclonal antibody (0.01-100 μg/ml; MEDI-545, MedImmune, Inc) or isotype matched control antibody of irrelevant specificity (R347, MedImmune, Inc) was added simultaneously with cytokine stimulus. Epidermal cultures were harvested at 2, 4, or 18 hours post treatment for transcript analysis. Expression of type-I IFN-induced genes was measured using a BIOMARK™ 48.48 dynamic array.
Expression of a majority of type-I IFN-induced genes was upregulated in the IFNα2a and leukocyte interferon stimulated keratinocytes in a dose-dependent manner. This upregulation of type-I IFN-induced genes, by either IFNα2a or leukocyte interferon, was likewise inhibited in a dose-dependent manner by IFNα monoclonal antibody (MEDI-545). Control antibody, R347, did not have a significant effect on neutralization of the type-I IFN-induced genes.
Dose-dependent neutralization of three type-I IFN-induced genes (ISG15, USP18, and IFIT2) by MEDI-545 in IFNα2a or leukocyte IFN stimulated keratinocytes is provided in
To identify the type-I IFN subtypes responsible for the induction of the type-I IFN signature in lesional skin of psoriasis patients, mRNA levels of type-I IFN genes in psoriatic lesions were measured.
Gene expression analysis was performed using a TAQMAN Low Density Array (TLDA) from Applied Biosystems. Expression of 23 genes, including type-I IFNα subtypes 1, 2, 5, 6, 7, 8, 14, 17, and 21; type-I IFNs IFNβ, κ, and ω; IFNγ; IFNα receptors IFNAR1 and IFNAR2; IFNγ receptors IFNGR1 and IFNGR2; type-I IFNα inducible genes RSAD2, OAS3, IFI44, MX1, and CXCL10; and TNFα was monitored and compared in paired lesional and non-lesional skin of 18 psoriasis patients.
Double-stranded cDNA for each patient sample was pre-amplified using the TAQMAN PreAmp Master Mix kit (Applied Biosystems). cDNA was pre-amplified by conducting 10 cycles of PCR on each patient sample using a pooled solution of primers, a pair for each gene analyzed on the array. The pre-amplified cDNA were diluted 1:5 with TE. A 50 μL volume of the diluted pre-amplified cDNA was added to a 50 μL volume of 2× TAQMAN Universal PCR Master Mix (Applied Biosystems) and mixed. The array was loaded with the mixture using standard procedures and the loaded array was run on a 7900HT Fast Real-Time PCR System (Applied Biosystems). Data analysis of the resulting Ct values was conducted with the SDSv2.2.2 software tool (Applied Biosystems).
a shows the relative overexpression of mRNA of nine IFNα subtypes in the lesional skin compared to either non-lesional skin or normal skin. With the exception of IFNα5 (upregulated by about 4.6 fold; median fold change, p<0.001), none of the IFNα subtypes were significantly altered at the mRNA level in the non-lesional skin compared to that in the normal skin (p<0.05). However, all of these IFNα subtypes were upregulated at the mRNA level in the lesional skin compared to that in the normal skin (or non-lesional skin), with the overexpression of IFNα1, IFNα5, IFNα8, IFNα14, IFNα17, IFNα21 being statistically significant (p<0.05).
Table 29, lists the correlation coefficients of the overexpression of type-I IFN family member (type-I IFNα subtypes 1, 2, 5, 6, 7, 8, 14, 17, and 21; and IFNβ, IFNκ, and IFNω) mRNAs in lesional skin compared to non-lesional skin of psoriatic patients. Of the 12 type-I IFN family members measured, overexpression of IFNα1, 2, 8, and 14 in lesional skin correlated most consistently with overexpression of other members in the type-I IFN family, with the exception of IFNα5 which showed the weakest correlation with other type-I IFN family members.
The involvement of IFNγ and TNFα mRNA signaling pathways was also evaluated in the paired lesional/non-lesional psoriasis and normal skin samples. As discussed in Example 15, above, TLDA from Applied Biosciences was used to measure IFNγ, IFNGR1 and IFNGR2, and TNFα mRNA in lesional and non-lesional skin of psoriasis patients and in normal healthy skin.
Unlike the observations for type-I IFN mRNA expression levels, IFNγ, IFNGR1, IFNGR2, and TNFα mRNAs were significantly overexpressed in non-lesional skin compared to healthy normal skin (
As described in Example 10, whole blood of healthy donors was stimulated ex vivo with a panel of IFNα subtypes, as well as IFNβ, IFNγ, and TNFα. Stimulating whole blood ex vivo with IFNγ or TNFα identified probe sets associated with potential IFNγ- or TNFα-inducible genes. Three hundred four probe sets were identified as at least 2-fold upregulated by IFNγ four hours post-stimulation. Two hundred thirty four probe sets were identified as at least 2-fold upregulated by TNFα both 2 and 4 hours post-stimulation.
The probe sets identified as associated with ex vivo IFNγ or TNFα induction were compared with the total 1408 probe sets (Example 11) found to be upregulated in lesional skin relative to non-lesional skin of psoriasis patients. Using this method, 106 and 35 of the probe sets included in the total 1408 upregulated in lesional skin were identified as IFNγ or TNFα inducible, respectively (
Also using the list of probe sets identified to be type I IFN, IFNγ and TNFα inducible from the ex vivo studies, type I IFN, IFNγ and TNFα inducible genes upregulated at least 2-fold in each of the lesional relative to non-lesional skin sample were identified.
Similar analysis was carried out for the downregulated genes in the lesional skin compared to the non-lesional skin of psoriatic patients (
Although IFNγ and TNFα mRNAs were found to be upregulated in the non-lesional skin of psoriatic patients when compared to healthy normal skin, IFNγ and TNFα inducible genes did not appear to be significantly overexpressed in the non-lesional skin (
To determine whether some of the highly overexpressed type I IFN inducible genes in psoriatic skin gave rise to similar changes in the expression of the proteins, immunohistochemical analyses were carried out to assess the presence of STAT1 and ISG15 protein in the skin. Furthermore, analysis of the cellular infiltrates (pDCs, mDCs and CD4-positive cells) was carried to compare the number of IFN-producing cell types and inflammatory cells in the biopsies of the lesional vs. non-lesional and normal skin.
Snap-frozen lesional psoriatic, non-lesional psoriatic, and normal skin biopsies were divided in half. One-half of each sample was embedded in O.C.T., sectioned at 5 μM, placed on a “plus” slide, and fixed in cold acetone. The sectioned samples were incubated with primary antibodies (specific for BDCA2, CD83, CD4, STAT1, and ISG15) for 4 hours and washed with TBS. The slides were then incubated with peroxidase-labeled polymer conjugated to goat anti-mouse immunoglobulin antibody (Envision+; Dakocytomation, Carpenteria, Calif.) for 30 minutes and washed with Tris-buffered saline, pH 7.2. Detection was performed with 3,3′-diaminobenzidiine tetrahydrochloride (DAB+; DakoCytomation) as the chromogen. Slides were washed with dH2O), counterstained with hematoxylin, dehydrated and coverslipped.
In all psoriasis patients for which paired lesional/non-lesional samples could be evaluated, lesional skin contained increased numbers of pDCs, and/or mDCs, increased numbers of CD4+ cells, as well as the significant upregulation of STAT-1 and ISG15 protein in the epidermis and dermis compared to non-lesional biopsies. By contrast, skin biopsies from normal donors did not contain appreciable numbers of pDCs, mDCs or staining for STAT-1 and ISG15. See
To determine whether transcripts of the top 25 type I IFN inducible genes in skin lesions of an SLE patient were neutralized by MEDI-545, biopsies from patients treated with 10 mg/kg MEDI-545 were examined. A heatmap of neutralization of the top 25 type I IFN inducible genes in skin lesions at 0 and 14 days post-treatment is provided in
To determine whether levels of some of the proteins expressed from these highly overexpressed type I IFN inducible genes were also reduced by treatment with 10 mg/kg MEDI-545, immunohistochemical analyses were carried out to detect HERC5, ISG15, and IP10 protein in SLE skin lesions of patients treated with MEDI-545 and placebo. Furthermore, analysis of the cellular infiltrates (pDCs, mDCs and CD4-positive cells) was carried out to compare the number of IFN-producing cell types and inflammatory cells in the biopsies of the SLE skin lesions of MEDI-545 treated patients and placebo treated controls.
Snap-frozen skin lesion samples of MEDI-545 treated SLE patients and placebo treated SLE patients were divided in half. One-half of each sample was embedded in O.C.T., sectioned at 5 μM, placed on a “plus” slide, and fixed in cold acetone. The sectioned samples were incubated with primary antibodies (specific for BDCA2, CD83, CD4, IP10, and ISG15) for 4 hours and washed with TBS. The slides were then incubated with peroxidase-labeled polymer conjugated to goat anti-mouse immunoglobulin antibody (Envision+; Dakocytomation, Carpenteria, Calif.) for 30 minutes and washed with Tris-buffered saline, pH 7.2. Detection was performed with 3,3′-diaminobenzidiine tetrahydrochloride (DAB+; DakoCytomation) as the chromogen. Slides were washed with dH2O), counterstained with hematoxylin, dehydrated and coverslipped.
In placebo-treated SLE patients both cellular infiltrates and levels of proteins expressed from overexpressed type I IFN inducible genes increased (or worsened) over the course of 14 days. See
By contrast, in patients treated with 10 mg/kg MEDI-545 levels of infiltrates and proteins expressed from overexpressed type I IFN inducible genes were decreased by varying degrees. See
To devise an assay to sensitively detect type I and type II IFNs a construct containing the gene for a luciferase enzyme isolated from the marine organism Gaussia princeps (Targeting Systems; Santee, Calif.) under the control of an interferon-stimulated response element (ISRE) (TAGTTTCACTTTCCC)5 (SEQ ID NO: 2); Biomyx; San Diego, Calif.) was cloned. HEK293H cells were stably transfected with the construct and these cells were used for the IFN detection assays.
25,000 of the stably transfected HEK293H cells were seeded per assay well in 50 uL of cell culture medium overnight in a CO2 incubator. The following day, patient serum samples (or normal pooled human serum spiked with the various sub-types of IFN alpha or IFN-beta, IFN-omega, IFN-gamma) were screened for detection of the various subtypes of IFN by adding 50 uL of undiluted patient or spiked serum to the assay wells containing the seeded cells (final concentration of 50% patient sera in the wells for 24 hours). IFN-induced luciferase activity was detected the following day, by observing chemiluminescence in the culture supernatants. Chemiluminescence was observed by transferring 50 uL of supernatant from the wells to a B&W Isoplate, adding 50 uL of chemiluminescent substrate, and detecting luminescence at 6 minutes. Samples generating a signal greater than 1.5-times the Negative Control wells on each assay plate are classified as Positive for IFN activity. See
In samples where IFN activity is detected, antibodies that specifically neutralize various Type I and Type II IFNs can then be used to determine which IFN was responsible for the positive response. Anti-IFN-type specific antibodies are pre-incubated with either the positive serum sample(s) (in the case of MEDI 545, anti-IFN beta, anti-IFN gamma and anti-IFN omega that bind to the IFN ligand itself) or with the cells (in the case of MEDI 546 that binds to the Type I interferon receptor on the HEK293H cells) followed by addition of the samples to the cells and chemiluminescence determination as above. Spiked samples that demonstrate lower chemiluminescence following specific antibody treatment are considered to be positive for the presence of the particular IFN(s) that is neutralized by the IFN-specific antibodies.
a) shows that increasing dose of MEDI-545 in the treated wells increasingly neutralizes of IFN activity as does increasing dose of MEDI-546 (
Serum was collected from SLE (n=40) and CLE (n=5) patients that had a history of at least 4 of 11 positive ACR classification criteria and demonstrated active disease manifestations at the time of sample collection. Ninety-five percent were female, with mean±SD age of 41±15 years. Seventy-six percent were currently receiving oral corticosteroids in doses ranging from 1 mg/d to 30 mg/d prednisone, with 2 SLE patients also receiving pulse intravenous steroids. Fifty-nine percent were receiving at least 1 potential disease-modifying medication other than corticosteroids. Luminex xMAP technology was used to detect changes in 89 analytes and was performed by Rules Based Medicine (see the world wide web at domain name rulesbasedmedicine.com). Results for each analyte were compared to the mean of a panel of normal human serum (n=17) and significance was determined using a paired t-test.
The QUANTIGENEPLEX assay was first performed to assess the ability of QUANTIGENEPLEX to detect 22 IFN-inducible transcripts in whole blood stimulated with IFNα2b. The 22 IFN-inducible transcripts detected by this initial QUANTIGENEPLEX assay were selected based on their consistent up-regulation in SLE patients and are shown on the x-axis of the graphs shown in
Stimulation of the whole blood was performed by incubating freshly drawn Na-EDTA whole blood from 5 healthy donors with 20 IU/mL IFNα2b for 4 hours. Following this incubation, 2.5 mL of the stimulated whole blood was added to PAXgene tubes, mixed, and held overnight at room temperature. After overnight incubation, the samples were frozen at −80° C. These sample-handling procedures were selected to mimic those to be used during clinical trials.
PAXgene blood was analyzed for expression levels of the IFN-inducible transcripts. PAXgene blood (500 μL) was pelleted and then lysed in 139 μL of buffer according to the QUANTIGENEPLEX PAXgene Blood Lysis Protocol. Processed blood from each donor was split into duplicate wells and hybridized overnight with a multiplex probe set for the 22 IFN-inducible genes. Gene expression was assessed the following day using a Luminex 100 instrument with BioRad BioPlex software. Fold changes were assessed for each individual based on the increase in signal observed between IFN-stimulated and PBS-stimulated control wells.
Whole blood of a single volunteer was further stimulated over a dose range of 0.2 to 200 IU/mL IFNα2b to determine whether upregulation of the IFN-inducible genes by IFNα2b was dose-dependent and could be detected by the QUANTIGENEPLEX assay. For each of the 22 transcripts, a dose-dependent induction was observed. See
Next, the QUANTIGENEPLEX assay was used to detect levels of IFN-inducible transcripts in whole blood of SLE patients. Twenty of the 22 probes from the original QUANTIGENEPLEX kit, probes identified in
The data obtained from the QUANTIGENEPLEX assay was next evaluated for its comparability to data obtained from a FLUIDIGM Real-Time PCR assay. QUANTIGENEPLEX and FLUIDIGM methods were each used to analyze and compare transcript levels in PAXgene-preserved whole blood samples from 16 SLE patients participating in a Phase I clinical trial (of a monoclonal antibody against IFNα) relative to a composite median gene score from 10 healthy donors. FLUIDIGM analyses were carried out using a mixture of TAQMAN Gene Expression assays, including 4 reference control genes prepared using the TAQMAN PreAmp Master Mix Kit (Applied Biosystems). Dynamic arrays were loaded using a NanoFlex 4-IFC Controller (FLUIDIGM Corp) and real-time reactions were performed using a BIOMARK Real-Time PCR System. Results were analyzed using BIOMARK Real-Time PCR Analysis software. Delta-delta Cts (DDCt) were calculated using the mean of 4 reference genes (GAPDH, TFRC, b2M, and 18S) and a calibrator sample. The results obtained using whole blood samples from SLE patients demonstrated a high degree of correlation between QUANTIGENEPLEX and Real-Time PCR approaches to detect disease-related gene expression profiles.
Data obtained from the QUANTIGENEPLEX and FLUIDIGM Real-Time PCR assays were further compared in their ability to detect changes in transcript levels in SLE patient samples over the course of treatment in a clinical trial. For this comparison, SLE patient samples were collected directly into PAXgene tubes on Day 0 (pre-dose) and multiple subsequent time points following administration of a single dose of an anti-IFNα monoclonal antibody or placebo. For each sample, an aggregate median fold-change was calculated from the panel of 22 genes and compared to the pre-dose sample for that patient.
