– Additional CALLIPER MRI Analyses Show Reductions for Vidofludimus Calcium in Acute and Chronic Inflammatory Disease Activity –
– CALLIPER Subset Data Demonstrate Reductions in EBV-Specific T-Cell Receptor Sequences, Underlining Broad-Spectrum Antiviral Effects of Vidofludimus Calcium –
NEW YORK, Feb. 4, 2026 /PRNewswire/ — Immunic, Inc. (Nasdaq: IMUX), a late-stage biotechnology company pioneering the development of novel oral therapies for neurologic and gastrointestinal diseases, today announced the presentation of additional data from its phase 2 CALLIPER trial evaluating lead asset, nuclear receptor-related 1 (Nurr1) activator, vidofludimus calcium (IMU-838), in patients with progressive multiple sclerosis (PMS) at the Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) Forum 2026, taking place from February 5-7, in San Diego, California. Both poster presentations will be accessible on the “Events and Presentations” section of Immunic’s website at: https://ir.imux.com/events-and-presentations. Additionally, members of Immunic’s management, medical and preclinical teams will be available throughout the event at booth #N9. “Together, our two poster presentations at the prestigious ACTRIMS Forum further underscore the unique mechanism of action of vidofludimus calcium and its potential in PMS,” stated Daniel Vitt, Ph.D., Chief Executive Officer of Immunic. “These latest findings from our phase 2 CALLIPER trial provide additional evidence of vidofludimus calcium’s effects on key biological drivers of disease progression, including antiviral immune responses linked to Epstein-Barr virus (EBV) and magnetic resonance imaging (MRI) markers of both acute-focal and chronic-compartmentalized inflammation. The findings further reinforce our belief that vidofludimus calcium has the potential to address underlying mechanisms of disease progression in multiple sclerosis (MS) patients.” Presentation Details:- Poster Title: Effect of Vidofludimus Calcium, a Novel Nurr1 Activator and Selective DHODH Inhibitor, on MRI Outcomes in Progressive Multiple Sclerosis: Data from the Phase 2 CALLIPER Trial

Vidofludimus calcium is an orally administered investigational small molecule drug being developed for chronic inflammatory and autoimmune diseases, currently in late-stage clinical trials for multiple sclerosis (MS). Uniquely, vidofludimus calcium’s first-in-class, dual mode of action combines neuroprotective, anti-inflammatory and anti-viral effects to target the complex pathophysiology of MS. As a selective immune modulator, it activates the neuroprotective transcription factor, nuclear receptor-related 1 (Nurr1), which provides direct and indirect neuroprotective effects. Additionally, vidofludimus calcium achieves anti-inflammatory and anti-viral effects through highly selective inhibition of the enzyme dihydroorotate dehydrogenase (DHODH). Vidofludimus calcium is currently being evaluated in phase 3 clinical trials for the treatment of relapsing MS. In a phase 2 clinical trial, it has shown therapeutic activity in relapsing-remitting MS patients, significantly reducing brain lesions and demonstrating encouraging results in reducing confirmed disability worsening. Additionally, vidofludimus calcium has demonstrated clinical benefits in progressive MS patients by showing substantial reductions in confirmed disability worsening and thalamic brain volume in a phase 2 clinical trial. To date, vidofludimus calcium has been exposed to approximately 2,700 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 late-stage biotechnology company pioneering the development of novel oral therapies for neurologic and gastrointestinal diseases. The company’s lead development program, vidofludimus calcium (IMU-838), is currently in phase 3 clinical trials for the treatment of relapsing multiple sclerosis, for which top-line data is expected to be available by the end of 2026. It has already shown therapeutic activity in phase 2 clinical trials in patients suffering from relapsing-remitting multiple sclerosis and progressive multiple sclerosis. 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 as well as inflammatory bowel disease, Graft-versus-Host-Disease and weight management. IMU-381, which currently is in preclinical testing, is a next generation molecule being developed to specifically address the needs of gastrointestinal diseases.
