Multicenter Study to Evaluate CRx-102 vs. Each of Its Components to Treat Active Rheumatoid Arthritis

The study was discontinued before the enrollment objective was met. Preliminary review of the efficacy dataset revealed that the efficacy dataset was not robust enough to support an extensive formal efficacy analysis as described in the SAP. Therefore, only the CRP values over time and the percent change in C-reactive protein (CRP) values in the As-Treated population were calculated.

Inclusion criteria

• Subject must be ≥ 18 years of age
• Subject must have RA (ACR criteria)
• Subject must have at least 4 swollen joints and at least 6 tender joints at screening and baseline (28 joint count)
• Subject must have a CRP > Upper Limit of Normal at screening
• Subject must have been on DMARD or DMARD combination (e.g. MTX + hydroxychloroquine) for at least 3 months and be on a stable dose of DMARD(s) for at least 6 weeks prior to screening.
• For MTX subjects: MTX ≥ 7.5 mg weekly (po/sc/im) and willing to take folic acid or folinic acid supplementation
• Subject willing to take concomitant multivitamin or the equivalent of 400 I.U. vitamin D and the equivalent of 1000 mg of elemental calcium daily
