NEW YORK, Oct. 22, 2024 /PRNewswire/ -- 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.
"While Immunic remains blinded to all data, the IDMC's favorable recommendations in this interim analysis corroborate our initial assumptions for the design, powering and relapse rate of the twin phase 3 trials of vidofludimus calcium in RMS, and suggest that they are in line with the data observed so far," stated Andreas Muehler, M.D., M.B.A., Chief Medical Officer of Immunic. "In particular, the planned sample size seems appropriate to address the primary endpoint of time to first relapse. As the IDMC recommends, we are continuing the ENSURE trials unchanged, with completion expected in 2026."
"I am particularly excited about the positive outcome of the interim analysis of our phase 3 ENSURE trials, marking the successful achievement of a critical milestone for the program," added Daniel Vitt, Ph.D., Chief Executive Officer of Immunic. "We are confident in vidofludimus calcium's potential to transform the oral MS market and continue to believe that the phase 3 program provides a clear and straightforward path towards seeking potential regulatory approval in RMS. Our next clinical milestone for vidofludimus calcium is the top-line readout of our phase 2 CALLIPER trial in patients with progressive multiple sclerosis (PMS), which we expect to release in April of next year. If this data set continues to show a neuroprotective effect for vidofludimus calcium, we believe our drug may be positioned as first-in-class oral treatment option for PMS, a form of MS with highest unmet medical needs."
The interim futility analysis of the phase 3 ENSURE program was performed by an unblinded IDMC and based on a pre-specified assessment after approximately half of the planned first relapse events occurred in the double-blind treatment periods of each of the twin ENSURE-1 and ENSURE-2 trials. The analysis was intended to inform potential sample size adjustment and help prevent the final study readout from occurring before sufficient events have been achieved. The unblinded IDMC was asked to make two decisions: The first question, as to whether the trials are futile, was answered by the IDMC with "futility criteria have not been met." The second question, as to whether the sample size in each trial should be increased, was answered by the IDMC with "continue as planned." Both decisions were based on the conditional power of the trials at the time of the interim analysis. Immunic has remained blinded during the interim analysis and has not seen any of the data available to the IDMC to make their recommendations.
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.

About Vidofludimus Calcium (IMU-838)
Vidofludimus calcium is a small molecule investigational drug in development as an oral next-generation treatment option for patients with multiple sclerosis and other chronic inflammatory and autoimmune diseases. The selective immune modulator activates the neuroprotective transcription factor nuclear receptor related 1 (Nurr1), which is associated with direct neuroprotective properties. Additionally, vidofludimus calcium is a highly selective inhibitor of the enzyme dihydroorotate dehydrogenase (DHODH), which is a key enzyme in the metabolism of overactive immune cells and virus-infected cells. This mechanism is associated with the anti-inflammatory and anti-viral effects of vidofludimus calcium. Vidofludimus calcium has been observed to selectively act on hyperactive T and B cells while leaving other immune cells largely unaffected and enabling normal immune system function, e.g., in fighting infections. To date, vidofludimus calcium has been tested in more than 1,800 individuals and has shown an attractive pharmacokinetic, safety and tolerability profile. Vidofludimus calcium is not yet licensed or approved in any country.
About Immunic, Inc.
Immunic, Inc. (Nasdaq: IMUX) is a biotechnology company developing a clinical pipeline of orally administered, small molecule therapies for chronic inflammatory and autoimmune diseases. The company's lead development program, vidofludimus calcium (IMU-838), is currently in phase 3 and phase 2 clinical trials for the treatment of relapsing and progressive multiple sclerosis, respectively, and has shown therapeutic activity in phase 2 clinical trials in patients suffering from relapsing-remitting multiple sclerosis, progressive multiple sclerosis and moderate-to-severe ulcerative colitis. Vidofludimus calcium combines neuroprotective effects, through its mechanism as a first-in-class nuclear receptor related 1 (Nurr1) activator, with additional anti-inflammatory and anti-viral effects, by selectively inhibiting the enzyme dihydroorotate dehydrogenase (DHODH). IMU-856, which targets the protein Sirtuin 6 (SIRT6), is intended to restore intestinal barrier function and regenerate bowel epithelium, which could potentially be applicable in numerous gastrointestinal diseases, such as celiac disease, for which it is currently in preparations for a phase 2 clinical trial. IMU-381, which currently is in preclinical testing, is a next generation molecule being developed to specifically address the needs of gastrointestinal diseases.
