A 12-week Study of 4 Doses of VX-509 in Subjects With Active Rheumatoid Arthritis

Completed · Phase 2 · Has a placebo group

Conditions studied: Rheumatoid Arthritis

In brief

This study is designed to evaluate safety and assess initial efficacy of VX-509, a JAK3 inhibitor, for treatment of subjects with active RA. This study will assess the clinical response of 4 doses of VX-509 compared to placebo when administered for 12 weeks to patients with active RA. The study will also evaluate the safety and tolerability of VX-509 compared to placebo when administered for 12 weeks to subjects with active RA.

• History of hematologic disorders including neutropenia and thrombocytopenia.
• Subjects with an acute or chronic active infection requiring systemic antimicrobial treatment, or subjects who are at high risk of developing an infection due to a compromised immune system.
