Detailed Description
This will be a randomized, double-blind, active- and placebo-controlled, parallel-group study in subjects with clinically active RA but who are MTX-naïve. Subjects who meet enrollment criteria will be randomized to 1 of 4 groups in a 2:2:2:1 ratio: CF101 1 mg, CF101 2 mg, MTX, or matching placebo tablets. CF101 or matching placebo will be administered every 12 hours for up to 24 weeks on treatment. MTX or matching placebo will be administered once a week Screening examinations will occur within 6 weeks prior to dosing. The following conventional drugs for RA treatment must be stable for the respective designated periods prior to the Screening Visit and must remain so during protocol participation: nonsteroidal anti-inflammatory drugs (NSAIDS), and corticosteroids for >1 month. All subjects will receive oral folate (minimum dose 5 mg/week) or oral folinic acid (up to 10 mg/week), based on the Investigator's preference.
Disease activity will be assessed using swollen and tender joint counts, erythrocyte sedimentation rate (ESR), and CRP. Efficacy will be assessed by Disease Activity Score 28 using the erythrocyte sedimentation rate (DAS28-ESR), ACR response criteria and European League Against Rheumatism (EULAR) response criteria : swollen and tender joint counts, physician global assessment (by visual analog scale, patient global assessment , patient reported pain, a Health Assessment Questionnaire (HAQ) Disability Index (DI) , Westergren ESR levels, and CRP levels. Assessments will occur at Screening, Baseline (Week 0), and Weeks 4, 8, 12 16, 20, and 24. At Weeks 12, 16, and 20, any subject who has not experienced at least 20% improvement in both the number of swollen and number of tender joints will be given rescue therapy with open-label oral MTX and followed through Week 24.
PK will be assessed in a subgroup of approximately 100 subjects at Week 0, Week 8, and Week 12. All subjects in the PK cohort will have samples collected for PK at time 0, and each subject will have additional samples drawn at 2 of the following post-dose time points: 1, 2, 3, 4, 6, and 8 hours. Whole blood sample for A3AR expression will be assessed in approximately 100 subjects at selected sites at Screening and Week 12, or end of dosing, if occurring before Week 12.
