About
This Phase 2b, multicenter, double-blind, placebo-controlled, randomized withdrawal study is designed to assess the efficacy and safety of IMVT-1402 in adult participants with active, difficult-to-treat, anti-citrullinated protein autoantibody (ACPA) positive rheumatoid arthritis (RA). The primary objective is to evaluate the effects of IMVT-1402 compared to placebo, as measured by the American College of Rheumatology 20% (ACR20) response.
Full description
The study consists of several periods. During the Screening Period (5 weeks) participants will undergo screening procedures to determine eligibility. In Period 1 (Open-Label Treatment), all eligible participants will receive open-label treatment with IMVT-1402 at a dose of 600 mg subcutaneous (SC) once weekly (QW) for 16 weeks. Participants who meet the ACR20 response criteria at Weeks 14 and 16 will be randomized in a 1:1:1 ratio to receive blinded treatment with either IMVT-1402 600 mg SC QW, IMVT-1402 300 mg SC QW, or placebo SC QW for 12 weeks in Period 2 (Randomized Withdrawal). Eligible participants who complete Period 2 at Week 28 will have the option to receive IMVT-1402 for an additional 48 weeks in Period 3 (Long -Term Extension). A follow-up visit will occur 4 weeks after the last dose of study treatment to monitor safety.
The primary endpoint of the study is the proportion of participants achieving an ACR20 response at the end of Period 2. Secondary objectives include evaluating the safety and tolerability of IMVT-1402, as well as its effects on other efficacy measures. This study aims to provide valuable data on the use of IMVT-1402 in treating adults with active, difficult-to-treat, ACPR-positive RA.
