Oral CF101 and Methotrexate Treatment in Rheumatoid Arthritis Patients
This trial will test the hypothesis that the addition of CF101, a novel anti-inflammatory agent, will improve the clinical condition of patients with rheumatoid arthritis who still have active joint inflammation despite taking methotrexate for at least 6 months.

|Official Title:||Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Study of the Safety and Efficacy of Daily CF101 Administered Orally, When Added to Weekly Methotrexate, in Patients With Active Rheumatoid Arthritis|
- ACR Efficacy Criteria [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]ACR 20 response (20% improvnent in RA based on swollen and tender joint counts, physician and patient global assessments of disease activity, a patient pain score) at endpoint (Week 12), with all-cause dropouts considered as nonresponders (nonresponder imputation) in the Intent-To-Treat (ITT) population
- ACR Criteria Components [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]ACR 20 response at all visits in the evaluable population and ACR 50 and ACR 70 responses at all visits in the ITT and evaluable populations using both nonresponder imputation and Last Observation Carried Forward (LOCF) analyses; change and percent change from baseline at each visit in the ITT and evaluable populations, analyzed using LOCF, in ACR response components [tender joint count, swollen joint count, patient assessment of pain by VAS, patient global assessment of disease activity by VAS, physician global assessment of disease activity by VAS, HAQ DI, CRP (by central laboratory, using an standard-sensitivity assay capable of detecting changes below the upper limit of normal) and ESR], Disease Activity Score (DAS28), and duration of morning stiffness.
- Safety [ Time Frame: 12 weeks ] [ Designated as safety issue: Yes ]Vital signs and weight, physical examinations, adverse event (AE) reporting, clinical laboratory testing, including liver function, renal function, complete blood count and clinical chemistries, urinalysis, and hematologic testing and 12-lead resting ECGs

This will be a multi-center, randomized, double-blind, parallel-group, placebo-controlled, dose-finding study in which patients with active RA despite receiving methotrexate for at least 6 months (at unchanged doses for >=2 months) will be randomized to the addition of either CF101 0.1 mg, CF101 1 mg, CF101 4 mg, or placebo given orally q12h for 12 weeks. Screening examinations will occur within 1 month prior to dosing. Washout of other disease-modifying antirheumatic drugs (DMARDs) (with the exception of hydroxychloroquine), including biological agents, will occur prior to dosing; if washout is necessary, patients must re-qualify for inclusion following the washout. Doses of nonsteroidal anti-inflammatory drugs (NSAIDS) and corticosteroids must be stable for >=1 month prior to dosing and remain so during protocol participation. Disease activity will be assessed using swollen and tender joint counts, duration of morning stiffness, physician and patient global assessments (by visual analog scale, VAS), patient reported pain (by VAS), a Health Assessment Questionnaire (HAQ) Disability Index (DI), Westergren erythrocyte sedimentation rate (ESR, Screening, Weeks 0 and12), and C-reactive protein (CRP) levels. Assessments will take place at Screening, Baseline (Week 0), and at Weeks 2, 4, 8, 12, and 14.
