Immunic, Inc. (Nasdaq: IMUX), a biotechnology company developing a clinical pipeline of orally administered, small molecule therapies for chronic inflammatory and autoimmune diseases, today announced a positive outcome of the non-binding, interim futility analysis of its phase 3 ENSURE program, investigating lead asset, nuclear receptor related 1 (Nurr1) activator, vidofludimus calcium (IMU-838), for the treatment of relapsing multiple sclerosis (RMS).
Based on the outcome of the interim futility analysis, an unblinded Independent Data Monitoring Committee (IDMC) has recommended that the trials are not futile and should continue as planned.
The ongoing ENSURE program comprises two identical multicenter, randomized, double-blind phase 3 trials designed to evaluate the efficacy, safety and tolerability of vidofludimus calcium versus placebo in RMS patients. Each of the trials, titled ENSURE-1 and ENSURE-2, is expected to enroll approximately 1,050 adult patients with active RMS at more than 100 sites in more than 15 countries, including the United States, India and countries in Latin America, Central and Eastern Europe. Patients are being randomized in a double-blinded fashion to either 30 mg daily doses of vidofludimus calcium or placebo and the primary endpoint for both trials is time to first relapse up to 72 weeks. Key secondary endpoints include time to confirmed disability worsening based on Expanded Disability Status Scale (EDSS) disability progression, volume of new T2-lesions, time to sustained clinically relevant changes in cognition, and percentage of whole brain volume change, grey matter volume and white matter volume. As previously reported, completion of ENSURE-1 is anticipated in the second quarter of 2026, with completion of ENSURE-2 expected in the second half of 2026.
