Phase 2b Study of Imeroprubart for Adults With Chronic Inflammatory Demyelinating Polyneuropathy CIDP Randomized, Double-Blind, Placebo-Controlled Treatment Trial

What this Trial Is About

Researchers are evaluating the efficacy and safety of Imeroprubart in adults with active Chronic Inflammatory Demyelinating Polyneuropathy CIDP, a condition affecting the peripheral nerves. This Phase 2b, multi-center, randomized, double-blind, placebo-controlled study aims to understand how well Imeroprubart works compared to placebo in treating CIDP. The study is sponsored by Immunovant Sciences GmbH and focuses specifically on adults meeting diagnostic criteria for typical or variant forms of CIDP. Participants will receive either Imeroprubart or a matching placebo by subcutaneous injection once weekly. The treatment period includes an initial 24-week phase Period 1 with Imeroprubart or placebo, followed by an extension to 52 weeks Period 2 for continued evaluation. Imeroprubart dosing is given once weekly via subcutaneous injection. Placebo is provided similarly during the first 24 weeks. During the study, participants will be monitored through clinical assessments including relapse status by Week 24, as well as measurements of disability, grip strength, muscle strength, and symptom scores. Electrodiagnostic tests support diagnosis at baseline. Safety and efficacy will be closely observed during treatment, with follow-up visits scheduled to assess outcomes. The total participation duration covers at least 24 weeks for the primary outcome assessment, with ongoing monitoring as defined by the study protocol.
