The vertical dashed lines partition the 3 classes of signature scores: 7 patients with a weak type I IFN gene signature=median fold change<1.91 (0.93 on log2 scale), 8 patients with a moderate type I IFN gene signature=median fold change between 1.91 and 5.53, and 20 patients with a strong type I IFN gene signature=median fold change>5.53 (2.47 on log2 scale). IFN=interferon; SLE=systemic lupus erythematosus.

DETAILED DESCRIPTION

The invention encompasses methods of identifying, diagnosing, treating, and monitoring disease progression in patients. 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. Alternatively, the patient may have the disease, disorder, or condition in the absence of experimental manipulation. Patients include humans, mice, rats, horses, pigs, cats, dogs, and any animal used for research.


The patient may comprise a type I IFN or IFNα-inducible PD marker expression profile. 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. Fold dysregulation can be calculated by well known methods in the art as can the comparing. See, e.g., Example 8.


The type I IFN or IFNα-inducible PD marker expression profile may comprise upregulation of any group of genes or group of genes detected by the probes identified in Tables 19, 20, 21, 22, 23, 24, 26, 28, or 30. The group of genes or group of genes detected by the probes identified in Tables 19, 20, 21, 22, 23, 24, 26, 28 or 30 may include any at least 2, any at least 3, any at least 4, any at least 5, any at least 6, any at least 7, any at least 8, any at least 9, any at least 10, any at least 11, any at least 12, any at least 13, any at least 14, any at least 15, any at least 16, any at least 17, any at least 18, any at least 19, any at least 20, any at least 21, any at least 22, any at least 23, any at least 24, any at least 25, any at least 26, any at least 27, any at least 28, any at least 29, any at least 30, any at least 40, or any at least 50 of the genes or genes detected by the probes identified in the Tables.

The patient may simply be identified as one who comprises upregulation of expression of IFNα receptors, either IFNAR1 or IFNAR2, or both, or TNFα, or IFNγ, or IFNγ receptors (either IFNGR1, IFNGR2, or both IFNGR1 and IFNGR2).


The upregulation or downregulation of the type I IFN or IFNα-inducible PD markers in the patient's expression profile may be by any degree relative to that of a sample from a control (which may be from a sample that is not disease tissue of the patient (e.g., non-lesional skin of a psoriasis patient) or from a healthy person not afflicted with the disease or disorder). The degree upregulation or downregulation may be at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 75%, at least 80%, at least 90%, at least 100%, at least 125%, at least 150%, or at least 200%, or at least 300%, or at least 400%, or at least 500% that of the control or control sample.

The patient may comprise auto-antibodies that bind to any number of these auto-antigens, e.g., any 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 11, at least 12, at least 13, at least 14, at least 15, at least 20, at least 25.


A type I IFN or an IFNα-inducible disease, disorder, or condition is any that exhibits a type I IFN or an IFNα PD marker expression profile or gene signature. A PD marker expression profile and a gene signature will be understood to be equivalent. These diseases, disorders, or conditions include those with an autoimmune component such as systemic lupus erythematosus, insulin dependent diabetes mellitus, inflammatory bowel disease (including Crohn's disease, ulcerative colitis, and Celiac's disease), multiple sclerosis, psoriasis, autoimmune thyroiditis, rheumatoid arthritis, glomerulonephritis, idiopathic inflammatory myositis, Sjogren's syndrome, vasculitis, dermatomyositis, polymyositis, and sarcoidosis. Other diseases, disorders, or conditions include graft versus host disease and transplant rejection.


The patients may also exhibit any of a number of symptoms as discussed in, e.g., provisional patent application Methods of Treating Systemic Lupus Erythematosis filed Apr. 16, 2007, or may have a clinical SLEDAI score or BILAG score as discussed in the same. 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.


The agent that binds to and modulates type I IFN or IFNα activity may neutralize a type I IFN or IFNα-inducible profile. Neutralization of the type I IFN or IFNα-inducible profile may be a reduction in at least one, at least two, at least three, at least five, at least seven, at least eight, at least ten, at least twelve, at least fifteen, at least twenty, at least twenty five, at least thirty, at least thirty five, at least forty, at least forty five, or at least fifty genes up-regulated by type I IFN or IFNα. The genes upregulated by type I IFN or IFNα may be any group of genes in Tables 19, 20, 21, 22, 23, 24, 26, 28, or 30 as discussed above. Neutralization of the type I IFN or IFNα-inducible profile is a reduction of at least 2%, at least 3%, at least 4%, at least 5%, at least 7%, at least 8%, at least 10%, at least 15%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 60%, at least 70%, at least 75%, at least 80%, or at least 90% of any of the at least one, at least two, at least three, at least five, at least seven, at least eight, at least ten, at least twelve, at least fifteen, at least twenty, at least twenty five, at least thirty, at least thirty five, at least forty, at least forty five, or at least fifty genes up-regulated in any type I IFN or IFNα-inducible profile. Alternatively, neutralization of the type I IFN or IFNα-inducible profile refers to a reduction of expression of up-regulated type I IFN or IFNα-inducible genes that is within at most 50%, at most 45%, at most 40%, at most 35%, at most 30%, at most 25%, at most 20%, at most 15%, at most 10%, at most 5%, at most 4%, at most 3%, at most 2%, or at most 1% of expression levels of those type I IFN or IFNα-inducible genes in a control sample. If the agent that binds to and modulates type I IFN or IFNα activity is a biologic agent, such as an antibody, the agent may neutralize the type I IFN or IFNα profile at doses of 0.3 to 30 mg/kg, 0.3 to 10 mg/kg, 0.3 to 3 mg/kg, 0.3 to 1 mg/kg, 1 to 30 mg/kg, 3 to 30 mg/kg, 5 to 30 mg/kg, 10 to 30 mg/kg, 1 to 10 mg/kg, 3 to 10 mg/kg, or 1 to 5 mg/kg.


Neutralization of the type I IFN or IFNα-inducible profile may be increased expression of at least one, at least two, at least three, at least five, at least seven, at least eight, at least ten, at least twelve, at least fifteen, at least twenty, at least twenty five, at least thirty, at least thirty five, at least forty, at least forty five, or at least fifty genes whose expression is reduced by type I IFN or IFNα. The genes whose expression is reduced by type I IFN or IFNα may be any group of genes in Table 30. Neutralization of down-regulated genes in a type I IFN or IFNα-inducible profile is an increase of at least 2%, at least 3%, at least 4%, at least 5%, at least 7%, at least 8%, at least 10%, at least 15%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 60%, at least 70%, at least 75%, at least 80%, or at least 90%, or at least 100%, or at least 125%, or at least 130%, or at least 140%, or at least 150%, or at least 175%, or at least 200%, or at least 250%, or at least 300%, or at least 500% of any of the at least one, at least two, at least three, at least five, at least seven, at least eight, at least ten, at least twelve, at least fifteen, at least twenty, or at least twenty five genes whose expression is downregulated in any type I IFN or IFNα-inducible profile. Alternatively, neutralization of the type I IFN or IFNα-inducible profile refers to an increase in expression of type I IFN or IFNα-inducible genes to within at most 50%, at most 45%, at most 40%, at most 35%, at most 30%, at most 25%, at most 20%, at most 15%, at most 10%, at most 5%, at most 4%, at most 3%, at most 2%, or at most 1% of expression levels of those type I IFN or IFNα-inducible (downregulated) genes in a control sample. If the agent that binds to and modulates type I IFN or IFNα activity is a biologic agent, such as an antibody, the agent may neutralize the type I IFN or IFNα profile at doses of 0.3 to 30 mg/kg, 0.3 to 10 mg/kg, 0.3 to 3 mg/kg, 0.3 to 1 mg/kg, 1 to 30 mg/kg, 3 to 30 mg/kg, 5 to 30 mg/kg, 10 to 30 mg/kg, 1 to 10 mg/kg, 3 to 10 mg/kg, or 1 to 5 mg/kg.

Up- or down-regulation of gene expression or activity of IFNα-inducible PD markers may be determined by any means known in the art. For example, up- or down-regulation of gene expression may be detected by determining mRNA levels. mRNA expression may be determined by northern blotting, slot blotting, quantitative reverse transcriptase polymerase chain reaction, or gene chip hybridization techniques. See U.S. Pat. Nos. 5,744,305 and 5,143,854 for examples of making nucleic acid arrays for gene chip hybridization techniques.

An IFNα-inducible PD marker expression profile may comprise a profile of protein activity. Up- or down-regulation of gene expression or activity of IFNα-inducible PD markers may be determined by detecting activity of proteins including, but not limited to, detectable phosphorylation activity, de-phosphorylation activity, or cleavage activity. Furthermore, up- or down-regulation of gene expression or activity of IFNα-inducible PD markers may be determined by detecting any combination of these gene expression levels or activities.


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 that identify candidate therapeutics, cells comprising an IFNα-inducible PD marker expression profile are contacted with an agent. The cells may be any type of cells, such as commercially available immortalized cell lines that comprise an IFNα-inducible PD marker expression profile, commercially available immortalized cell lines that have been treated with IFNα to induce an IFNα-inducible PD marker expression profile, cells isolated from a patient having an IFNα-inducible PD marker expression profile, or cells isolated from a healthy patient and treated with IFNα to induce an IFNα-inducible PD marker expression profile.


Presence or absence of a change in the IFNα-inducible PD marker expression profile of the cells is detected following contacting the cells with the agent. Presence of change may be any change in IFNα-inducible PD marker expression profile including at least a 10% decrease in up-regulated expression or activity of at least 1 gene in the IFNα-inducible PD marker expression profile, at least a 20% decrease of the at least 1 up-regulated gene, at least a 30% decrease of the at least up-regulated 1 gene, at least a 40% decrease of the at least 1 up-regulated gene, at least a 50% decrease of the at least 1 up-regulated gene, at least a 60% decrease of the at least 1 up-regulated gene, at least a 70% decrease of the at least 1 up-regulated gene, at least a 75% decrease of the at least 1 up-regulated gene, at least an 80% decrease of the at least 1 up-regulated gene, at least an 85% decrease of the at least 1 up-regulated gene, at least a 90% decrease of the at least 1 up-regulated gene, at least a 95% decrease of the at least 1 up-regulated gene, at least a 96% decrease of the at least 1 up-regulated gene, at least a 97% decrease of the at least 1 up-regulated gene, at least a 98% decrease of the at least 1 up-regulated gene, at least a 99% decrease of the at least 1 up-regulated gene, or a 100% decrease of the at least 1 up-regulated gene. Alternatively, or in addition, presence of change may be any change in IFNα-inducible PD marker expression profile including at least a 10% increase in expression or activity of at least 1 down-regulated gene in the IFNα-inducible PD marker expression profile, at least a 20% increase of the at least 1 down-regulated gene, at least a 30% increase of the at least 1 down-regulated gene, at least a 40% increase of the at least 1 down-regulated gene, at least a 50% increase of the at least 1 down-regulated gene, at least a 60% increase of the at least 1 down-regulated gene, at least a 70% increase of the at least 1 down-regulated gene, at least a 75% increase of the at least 1 down-regulated gene, at least an 80% increase of the at least 1 down-regulated gene, at least an 85% increase of the at least 1 down-regulated gene, at least a 90% increase of the at least 1 down-regulated gene, at least a 95% increase of the at least 1 down-regulated gene, at least a 96% increase of the at least 1 down-regulated gene, at least a 97% increase of the at least 1 down-regulated gene, at least a 98% increase of the at least 1 down-regulated gene, at least a 99% increase of the at least 1 down-regulated gene, or a 100% increase of the at least 1 down-regulated gene.


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 level of any given up-regulated type I IFN or IFNα inducible PD marker may decrease 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 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 sample obtained after administration of the therapeutic agent may be obtained 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 12, or at least 14 days after administration of the therapeutic agent. The sample obtained after administration of the therapeutic agent may be obtained at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, or at least 8 weeks after administration of the therapeutic agent. The sample obtained after administration of the therapeutic agent may be obtained at least 2, at least 3, at least 4, at least 5, or at least 6 months following administration of the therapeutic agent.


Additional samples may be obtained from the patient following administration of the therapeutic agent. 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 12, at least 15, at least 20, at least 25 samples may be obtained from the patient to monitor progression or regression of the disease or disorder over time. Disease progression may be monitored over a time period of at least 1 week, at least 2 weeks, at least 3 weeks, at least 4 weeks, at least 5 weeks, at least 6 weeks, at least 7 weeks, at least 2 months, at least 3 months, at least 4 months, at least 5 months, at least 6 months, at least 1 year, at least 2 years, at least 3 years, at least 4 years, at least 5 years, at least 10 years, or over the lifetime of the patient. Additional samples may be obtained from the patient at regular intervals such as at monthly, bi-monthly, once a quarter year, twice a year, or yearly intervals. The samples may be obtained from the patient following administration of the agent at regular intervals. For instance, the samples may be obtained from the patient at one week following each administration of the agent, or at two weeks following each administration of the agent, or at three weeks following each administration of the agent, or at one month following each administration of the agent, or at two months following each administration of the agent. Alternatively, multiple samples may be obtained from the patient following an or each administration of the agent.


Disease progression in a patient may similarly be monitored in the absence of administration of an agent. Samples may periodically be obtained from the patient having the disease or disorder. Disease progression may be identified if the number of type I IFN or IFNα inducible PD markers increases in a later-obtained sample relative to an earlier obtained sample. The number of type I IFN or IFNα inducible PD markers may increase 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. Disease progression may be identified if level of any given up-regulated type I IFN or IFNα inducible PD marker increases 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%. Disease progression may be identified if level of any given down-regulated type I IFN or IFNα inducible PD marker decreases 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 up-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. The number of down-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 increased number and increased level of up-regulated type I IFN or IFNα inducible PD marker may indicate disease progression. Alternatively, or in combination, any combination of decreased number and decreased level of down-regulated type I IFN or IFNα inducible PD marker may indicate disease progression. Disease regression may also be identified in a patient having a disease or disorder, not treated by an agent. In this instance, regression may be identified if the number of type I IFN or IFNα inducible PD markers decreases in a later-obtained sample relative to an earlier obtained sample. The number of 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. Disease regression may be identified if level of any given up-regulated type I IFN or IFNα inducible PD marker decreases 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%. Disease regression may be identified if level of any given down-regulated type I IFN or IFNα inducible PD marker increases 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 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. 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. Disease progression or disease regression may be monitored by obtaining samples over any period of time and at any interval. Disease progression or disease regression may be monitored by obtaining samples over the course of at least 1 week, at least 2 weeks, at least 3 weeks, at least 4 weeks, at least 5 weeks, at least 6 weeks, at least 7 weeks, at least 2 months, at least 3 months, at least 4 months, at least 5 months, at least 6 months, at least 1 year, at least 2 years, at least 3 years, at least 4 years, at least years, at least 10 years, or over the lifetime of the patient. Disease progression or disease regression may be monitored by obtaining samples at least monthly, bi-monthly, once a quarter year, twice a year, or yearly. The samples need not be obtained at strict intervals.


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.

EXAMPLES
Example 1a
Initial Identification of Up-Regulated Genes in Lupus Patients

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)).

Example 1a
Validation of Genes Identified as Up-Regulated Genes in Lupus Patients

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.

Data were generated from 46 SLE patients and 24 healthy controls using SAM and FDR in R (see Methods).


Type I IFN-inducible genes are highlighted in bold.


FDR = false discovery rate;


SAM = significance analysis of microarrays;


SLE = systemic lupus erythematosus;


WB = whole blood.







FIG. 80 (top panel) shows a heat map of the expression of the 114 upregulated type I IFN-inducible probe sets in SLE patients and healthy controls. A total of 32/46 of the SLE patients profiled showed significant overexpression of the type I IFN gene signature. To confirm the observation that type I IFN-inducible genes are overexpressed in WB of SLE patients, WB was procured from 54 SLE patients in a prospective study. FIG. 81A shows the PCA plot of the 46 SLE patients in the first study using the 114 overexpressed type I IFN-inducible probes. A clear difference was observed between SLE patients that had distinct overexpression of type I IFN gene signature from healthy donors and SLE patients that had weak or nondetectable type I IFN gene signature in WB. FIG. 81B shows the PCA plot from the 54 SLE patients in the prospective study using the same 114 type I IFN-inducible probe sets identified. A similar separation of SLE patients was observed based on type I IFN gene signature as in FIG. 81A. The distribution of the type I IFN gene signature scores in the prospective study was also similar to that of the first study (data not shown). The ability to use the overexpressed type I IFN-inducible genes identified to segregate SLE patients into 2 distinct groups—patients with or without type I IFN gene signature—validated the accurate identification of overexpression in the type I IFN gene signature in WB of SLE patients.


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 (FIG. 80, second panel). The granulocyte gene signature was present in about 50% of the SLE patients profiled.


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 (FIG. 80, panels three, four, and five, respectively); this is in agreement with the observation of lymphopenia in SLE patients previously reported in the literature (Bennett L, Palucka A K, Arce E et al.: Interferon and granulopoiesis signatures in systemic lupus erythematosus blood. J Exp Med. 197(6), 711-723 (2003), Rivero S J, Diaz-Jouanen E and Alarcon-Segovia D: Lymphopenia in systemic lupus erythematosus. Clinical, diagnostic, and prognostic significance.

Data were generated from 46 SLE patients and 24 healthy controls using SAM and FDR in R (see Methods).


FDR = false discovery rate;


SLE = systemic lupus erythematosus;


SAM = significance analysis of microarrays;


WB = whole blood.






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 FIG. 83A. These genes were upregulated by an average of 8- to 92-fold, and all were significantly overexpressed (P<0.05). These observations provide evidence that type I IFN-inducible genes are significantly overexpressed in SLE patients. The consistency of the results among microarray and TAQMAN assays and the strong correlation (correlation coefficient>0.98) between microarray and TAQMAN assays for 21 IFN-inducible genes in 2 example SLE patients (FIGS. 83B and 4C) argues for their potential as PD and diagnostic markers in clinical trials that investigate anti-IFN-α approaches in the treatment of SLE.


Example 2
Potential PD Markers Selected from Genes Up-Regulated in Lupus Patients

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.

Example 3
Candidate PD Markers Exhibit Minimal Variation in Healthy Donors

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).

Example 4
IFNα Stimulates Up-Regulation in Expression of Candidate PD Markers in Whole Blood of Healthy Volunteers

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 FIG. 1 (IFI44), FIG. 2 (IRF2), FIG. 3 (RSAD2), FIG. 4 (G1P3), and FIG. 5 (HERC5) for a graphical analysis of these candidate PD marker expression results.


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 FIG. 17. A heat map with a summary hierarchical clustering is also provided for 689 type I IFN inducible probe sets used on whole blood samples from healthy donors ex vivo stimulated with IFN type 1, IFN type 2, or TNFα. See FIG. 64.

Example 5
IFNα Ab Neutralizes IFNα-Induced Candidate PD Marker Expression in Healthy Volunteers' Whole Blood
Source of Interferon=IFNα2a

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.

Source of Interferon=SLE Patient Serum

(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 FIG. 67. The anti-IFN-α mAb treatment (lanes 4-6) demonstrated strong neutralization of a large number of genes stimulated with the serum of an SLE patient. Furthermore, neutralization by the anti-IFN-α mAb was dose-dependent, which suggests that these genes could be good candidates for PD. The reference mAb itself inhibited the overexpression of some of the genes upregulated when challenged with SLE patient sera; some of these were identified as type I IFN-inducible genes. However, the effect of anti-IFN-α mAb was much broader, with strong neutralization observed in a large number of genes of which neither the reference mAb nor anti-IFN-γ mAb had any significant effect (lane 2; lanes 4-6). It should be noted that treatment with anti-IFN-αR mAb (lane 7) induced more neutralization than anti-IFN-α mAb, which suggests the presence of other type I IFN family members in the serum of the SLE patients, in addition to IFN-α.


(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. FIG. 70a shows the range of levels of type I IFN activity in each of the four SLE patient serum samples.


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). FIG. 70b shows the number of probes detected as 3-fold or more upregulated in the healthy volunteer PBMCs by each of the four SLE patient serum samples. The number of probes detected as 3-fold or more upregulated by an SLE patient serum sample correspondingly increased with the level of type I IFN activity detected in the SLE serum sample.


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. FIG. 71a provides heat maps showing the percent neutralization of probes that were identified as upregulated following anti-IFNαtreatment for type I IFN genes (689 probes) and non-type I IFN genes (probes induced by SLE serum outside of type I IFN gene list) 4 and 18 h post incubation. FIG. 71b shows, for each of the four SLE patient serum samples, the percentage of type I IFN gene signature or non-type I IFN gene signature probes that were neutralized by the anti-IFNα treatment following both the 4 and 18 hour incubations. It appears that the majority of genes neutralized by anti-IFNα treatment of SLE serum-treated healthy volunteer's PBMCs 4 hours post-incubation were type I IFN genes, while the majority of genes neutralized by anti-IFNα treatment of SLE serum-treated healthy volunteer's PBMCs 18 hours post-incubation were non-type I IFN genes.


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. FIG. 72 provides the (a) type I IFN genes and (b) non-type I IFN genes that were identified as unique genes. Shaded areas indicate greater than 50% neutralization by anti-IFNα in that patient 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 FIG. 73, which provides a table showing the pathway analysis of altered genes and proteins at the 18 hr time point. Pathways highlighted in yellow were also significantly altered in SLE serum samples. The cell pathways and processes neutralized by anti-IFNα treatment at the 18 hr time point were analyzed with the METACORE integrated software suite from GENEGO, Inc. using the identified unique genes. Only pathways with p-values≦0.05 were considered significant. The pathways shown were altered in at least 2 out of 4 SLE serum samples.

Administering MEDI-545 to Lupus Patients Neutralizes the IFNα-Inducible Candidate PD Marker Expression Pattern

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 FIG. 18, FIG. 23, and FIG. 24 which provide graphical representations of neutralization of these top 25 PD markers following administration of varying concentrations of the MEDI-545 IFNα Ab over various lengths of time. The top 25 PD markers measured in this study are provided in Table 19.

The neutralization of IFN-induced PD markers by MEDI-545 for several individual lupus patients was examined and is presented in FIGS. 19-21. FIGS. 19 and 20 are heatmaps showing the neutralization of the top 25 PD markers (see Table 19) for two individual lupus patients (FIG. 19, patient 1541; and FIG. 20, patient 1449). Each of these lupus patients received 3 mg/kg MEDI-545. Each exhibited neutralization of the top 25 inducible PD markers at 7 and 14 days post-MEDI-545 treatment.


Neutralization of the top 25 type I IFN inducible genes in whole blood of an SLE patient treated with high dose (30 mg/kg) MEDI-545 was also examined. A heatmap of neutralization of the top 25 type I IFN inducible genes at 1, 4, 7, and 14 days following administration of MEDI-545 is presented in FIG. 25(a). Neutralization of all genes can be seen following administration of MEDI-545. FIG. 25(b) is a PCA of target modulation based on the top 25 type I IFN inducible genes. The PCA diagram shows the progression of the treated SLE patient from a position directly opposite that of normal healthy donors prior to administration of MEDI-545 to a position where it clusters with the healthy donors after administration of MEDI-545.


The neutralization of 165 PD markers by MEDI-545 was examined in a further lupus patient dosed with a lower, 0.3 mg/kg dose, of Ab. See FIG. 21. MEDI-545 neutralized most of the 165 candidate PD markers in this lupus patient. The 165 candidate PD markers are shown as the first 165 entries of Table 20.


The neutralization of type I IFN inducible probes sets was not observed in SLE patients treated with placebo control. Compare PCA plots of SLE patients before (a) and after (b) dosing with placebo in FIG. 26. Thus, the neutralization of the type-I IFN PD markers was due to the MEDI-545 antibody.


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%.

Example 7
The Majority of Lupus Patients Exhibit a Type I IFN-Inducible PD Marker Expression Pattern

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 FIG. 22 for PCA analysis results. The 169 probe sets used for this PCA analysis are provided in Table 20.

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 FIG. 68a for PCA analysis results and 68b for 25 genes used in the PCA analysis.


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 FIG. 65 provide further evidence that a high percentage of SLE patients share at least 2-fold overexpression of each individual type I IFN genes.

Overexpression of these genes, as detected initially using the Affymetrix arrays, was confirmed by FLUIDIGM dynamic array, validating their overexpression. See FIG. 69.


Example 8
MEDI-545 Considerably Neutralizes the Type I IFN Gene Signature of SLE Patients Having a Strong to Moderate Type I IFN Gene Signature

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 FIG. 28.


Treatment of these different SLE patient groups provided evidence that neutralization of the type I IFN gene signature by MEDI-545 is drug specific. FIG. 29(a) shows that in a group of SLE patients having a type-I IFN gene signature, virtually all of the top 39 genes neutralized 14 days post-MEDI-545 treatment are type I IFN signature genes (see yellow highlighted genes; percentage inhibition of the type I IFN signature genes ranged from 30.5-64.7). By contrast, none of the top 39 neutralized genes in SLE patients who received placebo were type I IFN signature genes. See FIG. 29(c). The SLE patients who lacked a type I IFN signature and were treated with MEDI-545 displayed an intermediate neutralization pattern, with some type I IFN signature genes neutralized. (See FIG. 29(b); yellow highlighting indicates type I IFN signature genes, which were neutralized from 19%-44.9%).


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. FIG. 84 shows the distribution of the type I IFN gene signature scores of the 46 SLE patients profiled. The SLE patients were profiled into 3 groups based on their type I IFN gene signature score: high type I IFN gene signature (score>10); moderate type I IFN gene signature (score 4-10); and weak type I IFN gene signature (score<4).


Selection of a Panel of 21 Type I IFN-Inducible Genes in WB of SLE Patients

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 FIGS. 86 and 89. Heatmap (FIG. 87a) and PCA calculations (FIG. 87b) using these 21 genes showed neutralization of the upregulated IFN α/β gene signature in an SLE patient treated with 30 mg/kg MEDI-545, but not in placebo-treated SLE patients (FIG. 88). Thus, it is evident that these genes could be used as a PD marker set.


Stratification of 35 Patients, by Strength of Type I IFN Gene Signature Using the 21 Genes


FIG. 85 shows the stratification of 35 SLE patients into groups of high (20 patients), moderate (8 patients), and weak (7 patients) type I IFN gene signatures based on the distribution of fold change values (log2 scale) of all 21 type I IFN-inducible genes and partitioned into each group by the median fold change of this distribution of 21 genes for each patient (vertical dashed lines), as measured by the dynamic array from FLUIDIGM. From FIG. 85, it is apparent that each patient distribution exhibits slight differences in skewness and basic shape/form, as this indicates the diversity in the various severity levels of SLE, based on the 21 type IFN-inducible gene selected. In a PCA plot for all SLE patients profiled in this study (n=100) and for the 24 healthy control samples using the 21 type I IFN-inducible genes, a clear distinction between SLE patients with an overexpressed type I IFN gene signature and those with weak or nondetectable type I IFN gene signatures is observed (FIG. 82C). Furthermore, the SLE patients with weak or nondetectable type I IFN gene signatures were clustered together with healthy donors. Importantly, the partitioning between these groups using the 21-gene panel of type I IFN-inducible genes was similar to that observed with the larger 114-gene set (FIGS. 81A and 81B).


Example 9
Multiple Type-I IFN Subtypes are Up-Regulated in Whole Blood of SLE Patients

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).



FIG. 27 shows the relative overexpression of mRNA of nine IFNα subtypes in the whole blood of lupus patients relative to healthy volunteers. Many of these IFNα subtypes were upregulated at the mRNA level in the whole blood of SLE patients.



FIG. 66 shows that IFNβ, IFNω and IFNAR1 and IFNAR2 genes are also overexpressed in whole blood of lupus patients relative to healthy volunteers.



FIG. 82 shows that TNF-α, IFN-γ, IFN-γR1, and IFN-γR2 transcripts were also upregulated in WB of SLE patients (FIG. 82). However, the relative magnitude of overexpression of these transcripts was less than that of the type I IFN family members, especially the IFN-α subtypes.


Example 10
Ex Vivo IFN-Stimulated Whole Blood and Keratinocytes of Healthy Individuals Identifies a Panel of Type I IFN-Inducible Genes Relevant to Psoriasis

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

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.



FIG. 30 provides the hierarchical clustering of 1384 probe sets differentially regulated by either IFNα/β, or IFNγ, or TNFα in ex vivo stimulated whole blood. From this hierarchical clustering the similar response of whole blood to challenge with IFNα subtypes and IFNβ can easily be observed, as can the similar but distinctly different effect of IFNγ from IFNα/β, and the drastically different effect of TNFα from IFNα/β.



FIG. 31
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.


Keratinocytes

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.



FIG. 31
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 FIG. 31a). Many of the top 25 type-I IFN inducible probe sets in ex vivo stimulated whole blood are also induced in ex vivo stimulated keratinocytes. See, e.g., MX1, IFI27, OAS1, IFI6, IFI44L, etc.


In addition, many of these genes were among those most overexpressed in the lesional skin of psoriasis patients. See discussion in Example 11, below.


Example 11
Whole Genome Array Profiling Identified IFNα/β Signaling Pathway as the Most Significantly Activated Pathway in Lesional Skin of Psoriasis Patients

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. FIG. 45 provides a Venn diagram of the probe sets both upregulated (downregulated) in lesional skin and non-lesional skin relative to normal healthy skin. Only 70 of the 1408 upregulated probe sets in the lesional skin were also upregulated in non-lesional skin. Meanwhile, only 43 of the 1465 probe sets downregulated in the lesional skin were also downregulated in the non-lesional skin. These data suggested that the molecular events and biological changes from the non-lesional skin to lesional skin were quite different from those from the normal skin to the non-lesional 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 (FIG. 46). Components of the pathway like IFNα subtypes, IFNβ, IFNAR1, IFNAR2, STAT1, IRF1, MPL, ISG15, IFI6 were all significantly overexpressed in lesional skin compared to non-lesional skin of psoriatic patients.


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 FIGS. 47a and b for the top 100 upregulated probe sets in lesional skin. These genes included STAT1, a key component in forming the ISGF3 complex; IRF7, a master regulator of the IFNα/β mediated immune response; MYD88, which governs the induction of CD8+ T-cell responses with IRF7; IRF1, a transcriptional activator for the type-I IFN genes; OAS family members OAS1, OAS2, OAS3, mediators of resistance to virus infection; ISG15, a ubiquitin-like protein that becomes conjugated to many cellular proteins upon activation by IFNα/β; and members of the ISG15 signaling pathways such as USP18, UBE2L6, and HERC5. This enrichment of type I IFN genes indicated them as the most overexpressed genes in lesional skin of psoriatic patients.


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.

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.

FIG. 32 provides a graphic of the distribution of the average and median fold changes among the different pairs of lesional and non-lesional skin. The prevalent and uniform upregulation of the most overexpressed type-I IFN genes in lesional skin of psoriatic patients verified their usefulness as PD markers.


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.


Example 12
Expression of Type-I IFN Genes is not Significantly Altered in Normal Skin Relative to Non-Lesional Skin of Psoriatic Patients

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). FIG. 33 provides a graphical representation of the relative expression of 3 type-I IFN inducible genes (HPSE, OASL, and HERC6; included as top 50 type-I IFN-induced probe sets in lesional relative to non-lesional skin), and 1 non type-I IFN inducible gene (SERPINB4) in both (a) lesional skin compared to non-lesional skin and (b) non-lesional skin compared to normal skin. The overexpression of genes HPSE, OASL, and HERC6 in lesional skin compared to non-lesional skin is both statistically significant (as evidenced by the very small p value) and large in scale (between 12-250 fold overexpression on average). SERPINB4 is overexpressed in non-lesional skin by about 3-4 fold compared to normal skin, but upregulated by well over 200 fold in lesional skin compared to non-lesional 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. FIG. 34a provides heatmap of unsupervised hierarchical clustering of all lesional, non-lesional, and normal skin samples profiled using the 164 type-I IFN-inducible probe sets in lesional skin compared to non-lesional skin of psoriasis patients. It can be observed that nearly all (all but three) of the lesional skin samples clustered together, while nearly all of the non-lesional and normal skin samples clustered together. FIG. 34b provides a PCA plot of the skin samples using the same 164 upregulated type-I IFN inducible probe sets. Again, the normal skin samples and the non-lesional skin samples mostly clustered together, indicating similar levels of expression of the 164 genes. Also, the majority of the lesional skin samples were separated from the normal and non-lesional skin samples, indicating that the lesional samples exhibited a distinct overexpression of the type-I IFN inducible genes that was separable from the gene expression levels of the normal and non-lesional 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 FIG. 47.


Example 13
Validation of Type-I IFN-Inducible Gene Up-Regulation in Psoriatic Lesional Skin Using TAQMAN-Based Assays

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. FIG. 35 provides TAQMAN data showing overexpression of each of ten (OAS2, OASL, EPSTI1, MX1, IFI44L, IFI44, HERC6, HPSE, ISG15, and STAT1) type-I IFN-inducible genes in lesional skin in the 18 paired lesional/non-lesional samples.


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 FIG. 36a. Nineteen of the overexpressed genes had correlation coefficients greater than 0.85, indicating excellent correlation between the microarray and TAQMAN-based assay. Another 17 genes had high correlation coefficients between the microarray and TAQMAN-based assay of 0.5-0.85. FIG. 36b provides the distribution of correlation coefficients between the TAQMAN-based assay and the Affymetrix array for the 29 type-I IFN-induced genes of the 18 psoriasis patients. Again, many of the genes had high correlation coefficients, greater than 0.90. These genes include, inter alia, IFI27, CXCL10, ISG15, and MX1.



FIGS. 37
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. FIGS. 37a and 37b show similar overexpression of ISG15 in each of the 18 paired lesional/non-lesional skin samples as determined by TAQMAN (37a) and microarray (37b) analysis. FIGS. 37c and 37d show similar overexpression of MX1 in each of the 18 paired lesional/non-lesional skin samples as determined by TAQMAN (37c) and microarray (37d) analysis. The correlation coefficient between the TAQMAN and microarray was 0.9735 for ISG15 and 0.9836 for MX1. FIG. 38 shows measurement of similar overexpression of type-I IFN-inducible genes IFI27 and CXCL10 by TAQMAN and microarray analysis in each if the 18 paired lesional/non-lesional skin samples. The correlation coefficient between the TAQMAN and microarray results for IFI27 and CXCL10 was 0.9456 and 0.9455, respectively.


Example 14
IFNα Ab Neutralizes Type-I IFNα-Induced Gene Expression in Ex Vivo Stimulated Keratinocytes of Healthy Volunteers

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 FIG. 39. FIGS. 39 (a), (c), and (e) show that MEDI-545 neutralizes overexpression of type-I IFN induced genes ISG15, USP18, and IFIT2, respectively, in keratinocytes stimulated with 350 IU/mL IFNα2a. Each of these genes was neutralized 100% by MEDI-545. FIGS. 39 (b), (d), and (f), show that MEDI-545 neutralizes overexpression of type-I IFN induced genes ISG15, USP18, and IFIT2, respectively, in keratinocytes stimulated with 150 I.U./mL leukocyte IFN. Neutralization of these genes by MEDI-545 was between 70 and 100%, which is not surprising because leukocyte IFN contains both IFNα and IFNβ. MEDI-545 neutralizes a majority of IFNα subtypes efficiently, but not IFNβ. These neutralization data provide further evidence that the type-I IFN-inducible genes identified in ex vivo stimulated whole blood and keratinocytes (Example 10) are type-I IFN-inducible genes. It also provides further support that upregulated expression of these genes in lesional psoriatic skin relative to non-lesional skin due to type-I IFN induction.


Example 15
Multiple Type-I IFN Subtypes are Up-Regulated in Lesional Skin of Psoriasis Patients

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).



FIG. 40
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). FIG. 40b shows that the overexpression of other members of type I IFN family members, IFNβ, -κ, and -ω mRNA in the lesional skin compared to either non-lesional skin or normal skin. The alterations of IFNβ and IFNω mRNAs in the non-lesional skin were not significant. However, the upregulation of these mRNAs were significant in the lesional skin compared to normal skin (p values of 0.022 and 0.049 respectively). IFNκ mRNA was upregulated by about 1.6 fold (median fold change, p=0.03) in the non-lesional skin, and was sharply upregulated by 62.6 fold (median fold change) in the lesional skin compared to normal skin (p<0.001). Additionally, the receptors for type I IFN, IFNAR1 and IFNAR2 were also significantly overexpressed in the lesional skin of psoriatic patients at transcript level (p values<0.001; FIG. 40c). While IFNAR2 upregulation was significant in the non-lesional skin, IFNAR1 was not (FIG. 40c). Collectively, these data provided strong evidence that mRNA levels of type I IFN family members were comparable between the non-lesional skin and healthy normal skin (with the exception of IFNα5 and IFNκ), and were uniformly overexpressed in the lesional skin of psoriatic patients.


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.

Example 16
Co-Overexpression of Type-I IFN, Type-II IFN, and TNFα and their Gene Signatures in Lesional Skin or Psoriasis Patients

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 (FIG. 41; p values of 0.02, <0.001, <0.001 and <0.001 respectively). TNFα mRNA was upregulated by about 5.7 fold, while IFNγ, IFNGR1 and IFNGR2 mRNAs were upregulated by about 1.5, 2.2, and 2.8 fold compared to that in the normal skin (median fold change; FIG. 41). However, like the type I IFNs, these genes were upregulated in the lesional skin compared to either non-lesional skin (p values of 0.04, 0.01, 0.001 and 0.007 respectively) or normal skin (p values<0.001 for all of them; FIG. 41). TNFα, IFNγ, IFNGR1 and IFNGR2 mRNAs were upregulated by about 33.5, 116.7, 11.6, and 8.4 fold in the lesional skin compared to that in the normal skin. These observations indicated that the mRNA expression patterns for IFNγ and TNFα are different from those of type I IFN family members, which were comparable between healthy skin and non-lesional skin (with the exception of IFNα5 and IFNκ), but upregulated in the lesional skin compared to non-lesional skin of psoriasis patients.


Example 17
Identification Genes Induced by Type II IFN and TNFα in Ex Vivo Stimulated Whole Blood and which are Induced in Skin Lesions of Psoriasis Patients

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 (FIG. 42). The 106 probe sets identified as IFNγ inducible are provided in FIG. 49. The 35 probe sets identified as TNFα inducible are provided in FIG. 50. The 164 probes sets shown in FIG. 42 as identified as type-I IFN inducible are provided in FIG. 51. The Fisher's exact test indicated that the p values (one-tailed t-test) of the overexpression of IFNγ or TNFα inducible genes in lesional skin were both less than 0.0001. The overexpression of IFNγ and TNFα inducible genes was significant.


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. FIG. 43 shows the number of type I IFN, IFNγ and TNFα inducible genes upregulated in each of the 26 paired lesional and non-lesional skin. The larger the number of type I IFN inducible genes upregulated in a particular lesional skin biopsy usually gave rise to the overexpression of larger numbers of IFNγ and TNFα inducible genes in the same lesional skin biopsy. This observation was confirmed by the strong correlation in the co-activation of these three sets of genes with correlation coefficients of 0.9811, 0.9179 and 0.9372 using two-tail paired t-test to compare the upregulation of type I IFN and IFNγ, type I IFN and TNFα, and IFNγ and TNFα inducible genes in lesional skin compared to non-lesional skin (FIG. 43a).


Similar analysis was carried out for the downregulated genes in the lesional skin compared to the non-lesional skin of psoriatic patients (FIG. 42). Of the 1465 total probe sets downregulated in lesional relative to non-lesional skin, only 17, 5, and 5 of them were type I IFN, IFNγ and TNFα inducible.


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 (FIG. 42). The absence of type I IFN, IFNγ and TNFα inducible gene signatures in the non-lesional skin compared to normal skin, even when IFNγ and TNFα mRNAs are overexpressed in the non-lesional skin, suggested that either IFNγ and TNFα proteins were not made in the non-lesional skin, or other signaling molecules might have inhibitory effect on the IFNγ and TNFα pathways in the non-lesional skin of psoriatic patients.


Example 18
Immunohistochemical Analysis of Biopsies from Lesional Psoriatic Skin, Non-Lesional Psoriatic Skin, and Skin from Normal Donors Shows Increased Protein Levels of Type I IFN-Induced Genes

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 FIG. 44 for example immunohistochemistry slides.


Example 19
Immunohistochemical and Gene Expression Analysis of Biopsies from SLE Patient Skin Lesions Show Reduced Expression of Type I IFN-Induced Genes at the Protein and Transcript Level Following Treatment with MEDI-545

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 FIG. 58(a). All of the top 25 genes are neutralized 14 days following administration of MEDI-545. A PCA diagram of target modulation based on these top 25 type I IFN-inducible genes is provided in FIG. 58(b). The PCA diagram shows the progression of the treated SLE patient from a position directly opposite that of normal healthy donors prior to administration of MEDI-545 to a position nearing that of the healthy donors 14 days after administration of MEDI-545.


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 FIG. 52 which shows an increase in (worsening of) mDC(CD83 staining) and T cell (CD4 staining) infiltration in skin lesions. FIG. 52 also shows no change in pDC (BDCA2 staining) infiltration in the placebo-treated SLE patient skin lesions over the 14 days. See also FIG. 53 which shows an increase in staining for proteins expressed from overexpressed type I IFN inducible genes HERC and IP10. No change in staining for ISG15 was observed.


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 FIGS. 54 and 55, which provide immunohistochemical data from a first SLE patient treated with MEDI-545 and FIGS. 56 and 57, which provide immunohistochemical data from a second SLE patient treated with MEDI-545.


Example 20
Assay for Sensitive Detection of Type I and Type II IFNs

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 FIG. 59a-d, which provide detected levels of type I and type II IFN activity in the IFN bioassay for different plates of cells treated with patient serum and spiked control serum. Each of panels a-d show that increased dose of IFN in the assay results in increased detection of IFN activity.


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.



FIG. 60(
a) shows that increasing dose of MEDI-545 in the treated wells increasingly neutralizes of IFN activity as does increasing dose of MEDI-546 (FIG. 60(b)). FIGS. 61-63 show that IFNγ, IFNω, and IFNβ, respectively, are neutralized by antibodies specific for IFNγ, IFNω, and IFNβ, as expected.


Example 21
Alterations of Levels of Soluble Proteins in Serum of Lupus Patients

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. FIG. 74 shows analytes whose levels were significantly (a) increased or (b) decreased from the mean of the normal serum (p value≧0.05). Significant alterations in levels of cytokines chemokines, metabolic proteins, and other soluble mediators were detected in serum of lupus patients.


Example 22
Alternative Assay, Panomics QUANTIGENEPLEX Assay, Verifies IFN-Induced Gene Expression Analysis Results

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 FIGS. 75 and 76.


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. FIG. 75 shows the fold-change in expression of each of the 22 IFN-inducible genes following IFN stimulation of each of the 5 healthy volunteer whole blood samples. The dashed line indicates a 2-fold change over PBS-stimulated control samples.


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 FIG. 76, which provides the fold change in expression for each of the 22 transcripts at each IFNα2b dosage. Maximal transcript induction of nearly 100-fold was observed for RSAD2, IFIT3, and MX1. Using a 2-fold increase over baseline as a cutoff criterion, 19/22 genes were detected in samples spiked with 2 IU/mL of IFN and 5/22 were detected in samples spiked with 0.2 IU/mL IFN. Expression of SIGLEC1, LY6E, SERPING1, OAS3 and IFI27 transcripts were poorly induced by IFNα2b stimulation. These low levels of induction may indicate a lack of sensitivity of the assay to these targets or differences in gene expression between actual SLE disease (from which this panel of transcripts was chosen) and ex vivo stimulation with a single IFNα subtype, IFNα2b. Dashed line indicates a 2-fold change over PBS-stimulated control samples.


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 FIGS. 75 and 76, were retained in the QUANTIGENEPLEX assay used for this data analysis. Two probes, HSXIAPAF1 and GIP3, were substituted with different probes, XAF1 and IFI6. Using this panel of 22 probes, a baseline gene signature was established based on whole blood samples of ten healthy donors (blue bars in each panel). The baseline gene signature, based on the whole blood samples of the healthy donors, was compared to (1) the gene signature of an SLE patient that had detectable IFN serum activity and (2) the gene signature of an SLE patient that did not have detectable IFN serum activity. IFN serum activity was detected in the SLE patient serum samples using the assay described in Example 20. FIG. 77a shows a comparison of the gene signature of an SLE patient (red bars) having no detectable serum IFNα activity (i.e. serum IFN activity<2.5 IU/mL) relative to the baseline gene signature (blue bars). With the exception of LAMP3, all transcript levels were detected as elevated in blood from the SLE patient with no IFN serum activity. FIG. 77b shows a comparison of the gene signature of an SLE patient with high levels of serum IFNα activity (red bars) relative to the baseline gene signature (blue bars). All transcripts were elevated at least 2-fold in the blood of the patient with high IFN serum activity, with maximal inductions of nearly 80-fold for IFI27.


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. FIG. 78 shows the (a) composite median and (b) mean-fold changes of all genes in the panels that were calculated and compared by Pearson's correlation analysis. Significant correlation was observed between QUANTIGENEPLEX and FLUIDIGM when median (p=0.0002) and mean (p<0.0001) fold changes were compared for the panel of genes.


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. FIG. 79a shows the changes in gene signature for placebo- or antibody-treated SLE patients using FLUIDIGM technology. FIG. 79b shows the changes in gene signature of the placebo- or antibody-treated SLE patients using QUANTIGENEPLEX technology. For each non-placebo subject, a decrease in IFN gene signature is observed within 24 hours following drug administration and is consistent between FLUIDIGM and QUANTIGENEPLEX. Subsequent changes in transcript levels post-administration were also highly similar between QUANTIGENEPLEX and FLUIDIGM technologies.
