Brief Summary:

This trial will test the hypothesis that the administration of CF101, a novel anti-inflammatory agent, to patients with rheumatoid arthritis and high A3AR expression at baseline will relieve signs and symptoms of the disease.

Condition or disease	Intervention/treatment	Phase
Rheumatoid Arthritis	Drug: CF101; Drug: Placebo control	Phase 2

Detailed Description:

This will be a multi-center, randomized, double-blind, parallel-group, placebo-controlled, study in which patients with active RA and high A3AR expression at baseline will be randomized to the addition of either CF101 1.0 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), 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, 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, and 12.

Primary Outcome Measures :

1. American College of Rheumatology (ACR20) [ Time Frame: 12 weeks ]
   Primary efficacy was assessed using ACR20 response at Week 12, with all-cause dropouts considered as non-responders, in the ITT population.

Secondary Outcome Measures :

1. Safety: Adverse Event Reporting, Physical Examination, Vital Signs, Clinical Laboratory Testing [ Time Frame: 12 weeks ]
2. ACR 20/50/70, ITT and Evaluable Population, Last Observation Carried Disease Activity Score (DAS28) Change From Baseline at Each Visit in the Efficacy Parameters [ Time Frame: 12 weeks ]
