Efficacy Study of MM-093 in Rheumatoid Arthritis Patients on Methotrexate (MTX)

Study Overview
=================
Brief Summary
-----------------
The purpose of this clinical study is to see if an experimental drug, called MM-093, is safe and effective in the treatment of rheumatoid arthritis. MM-093 is a genetically engineered version of a naturally occurring protein called alpha fetoprotein (AFP). Adults normally have very small amounts of AFP in their bloodstream. However, during pregnancy, AFP levels in both the mother and the fetus are much higher than normal. It has been observed that women with RA (Rheumatoid Arthritis) have fewer symptoms during pregnancy, particularly during the third trimester. At this time, the levels of AFP in the blood of the mother and fetus are the highest. This observation led researchers to begin examining AFP as a possible treatment for RA.

Understand, sign, and date the written voluntary informed consent form at the screening visit prior to any protocol-specific procedures being performed. Be able and willing to comply with study visits and procedures per protocol. Sexually active men must agree to use a medically acceptable form of contraception during the study and continue for 4 weeks after the last dose of study drug. Women of childbearing potential must use a medically acceptable means of birth control during the study and for 4 weeks after the last dose Must be able to store study drug in a refrigerator at home Exclusion Criteria: Use of any B-cell depleting therapy in the last 6 months Use of Leflunomide or Humira in the last 3 months Use of any investigational drug or biologic agent in the last 2 months Use of Remicade in the last 2 months Use of cyclosporine, sulphasalazine, auranofin, intramuscular gold, azathioprine, D-penicillamine or tacrolimus within the last 6 weeks Use of more than 10 mg/day of prednisone or equivalent in the last 4 weeks Use of intra-articular corticosteroid injection in the last 4 weeks Use of a bolus IM/IV (intramuscular/intravenous) treatment with corticosteroids (>20 mg prednisone or equivalent) in the last 4 weeks Use of Enbrel in the last 4 weeks Use of Kineret in the last 2 weeks Current use of more than 1 NSAID (non-steroidal anti-inflammatory drug) or dose of NSAID greater than the maximum recommended dose in the product information Cancer, or a history of cancer (other than successfully resected cutaneous basal and squamous cell carcinoma) within 5 years before the screening visit. Any condition for which participation in this study is judged by the physician to be detrimental to the patient, such as history of significant or unstable cardiac, pulmonary, gastrointestinal, neurological, or psychiatric disease, or a DMARD (Disease-Modifying Anti-Rheumatic Drug)-related severe, potentially life-threatening AE (Adverse Event). Significant ongoing infection requiring systemic antibiotic, antifungal, antiviral, or any anti-mycobacterial therapy. Autoimmune or connective tissue disorder other than rheumatoid arthritis (e.g. systemic lupus erythematosis, scleroderma or psoriatic arthritis). Grade 2 or above leukopenia (i.e. white blood cells < 3000/mm3 [SI units: < 3.0 x 10^9/L]). Thrombocytopenia or thrombocytosis (platelets < 125,000/mm3 or ≥ 1,000,000/mm3 [SI units: < 125 x 10^9/L or ≥ 1,000 x 10^9/L]), respectively. Grade 2 or above liver function abnormality (i.e. total bilirubin > 1.5 x the upper limit of normal; or aspartate aminotransferase [AST/SGOT] or alanine aminotransferase [ALT/SGPT] > 2.5 x upper limit of normal). Renal disease (including serum creatinine level > 1.5 x the upper limit of normal). Any history of immunodeficiency syndromes or infection with human immunodeficiency virus (HIV), or a history of hepatitis C or chronic hepatitis B. Pregnant or breastfeeding women or women planning to become pregnant during the study or within 4 weeks after the last dose of study drug. Any major surgery, including joint surgery, within 3 months before screening visit. Scheduled elective surgery during study participation. Participated in any previous clinical trial using MM-093 or have any prior exposure to MM-093. History of severe hypersensitivity to goat, sheep or cow milk or products derived from goat, sheep or cow milk (patients who are lactose intolerant are not excluded). Any other condition that the investigator feels would jeopardize the integrity of the study (e.g. a CTCAE [Common Terminology Criteria for Adverse Events] grade 2 or above clinical finding or laboratory result).
