OBJECTIVE: To assess early effects on joint structures of VX-509 in combination with stable disease-modifying antirheumatic drug (DMARD) therapy using MRI in adults with rheumatoid arthritis (RA).

METHODS: This phase II, placebo-controlled, double-blind, dose-ranging study randomised patients with RA and inadequate DMARD response to VX-509 100 mg (n=11), 200 mg (n=10) or 300 mg (n=10) or placebo (n=12) once daily for 12 weeks. Outcome measures included American College of Rheumatology score (ACR20; improvement of ≥20%) and disease activity score (DAS28) using C reactive protein (CRP), and the RA MRI scoring (RAMRIS) system.

RESULTS: ACR20 response at week 12 was 63.6%, 60.0% and 60.0% in the VX-509 100-mg, 200-mg and 300-mg groups, respectively, compared with 25.0% in the placebo group. DAS28-CRP scores decreased in a dose-dependent manner with increasing VX-509 doses. Decreases in RAMRIS synovitis scores were significantly different from placebo for all VX-509 doses (p<0.01) and for RAMRIS osteitis scores (p<0.01) for VX-509 300 mg. Treatment was generally well tolerated.

CONCLUSIONS: VX-509 plus a DMARD reduced the signs and symptoms of RA in patients with an inadequate response to a DMARD alone. MRI responses were detected at week 12. Treatment was generally well tolerated.
