Immunic, Inc.(NASDAQ:IMUX), a late-stage biotechnology company pioneering the development of novel oral therapies for neurologic diseases, today announced the presentation of one late-breaking and two additional posters highlighting 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 2026 Consortium of Multiple Sclerosis Centers (CMSC) Annual Meeting, taking place May 27-29, 2026 in Charlotte, NC. All poster presentations will be accessible on the "Events and Presentations" section of Immunic's website at: https://ir.imux.com/events-and-presentations. Additionally, Immunic team members will be available throughout the meeting at booth #307.

"We believe the new data presented in these three posters at the prestigious CMSC Annual Meeting continues to demonstrate a consistent and differentiated profile for vidofludimus calcium in multiple sclerosis (MS)," stated Daniel Vitt, Ph.D., Chief Executive Officer of Immunic. "The late-breaking analysis is particularly interesting, as it introduces a new and potentially more comprehensive way to measure overall disability change by capturing both slowing of progression and improvement of disease. Together with supportive safety, tolerability and patient-reported data, these findings further strengthen our confidence in the potential of vidofludimus calcium to address key drivers of MS disease progression."

"These post-hoc analyses from the phase 2 CALLIPER trial provide valuable insights as to the effects of vidofludimus calcium in patients with progressive MS," added Michael A. Panzara, M.D., M.P.H., Chief Medical Officer of Immunic. "Whereas disability in MS is commonly measured by 3- or 6-months confirmed disability worsening, our late-breaking poster presents a novel approach capturing both worsening and improvement on treatment, allowing for a more comprehensive assessment of well-being. In applying these assessments, we observed favorable effects of vidofludimus calcium versus placebo. These data, combined with a safety and tolerability profile that appears favorable, supports the continued development of vidofludimus calcium for progressive MS."

Late-Breaking Poster Presentation Details:

  • Poster Title: Novel Unified Statistical Analyses for Confirmed Disability Changes in Multiple Sclerosis for Capturing Possible Neuroprotective Effects
  • Presenting Author: James Myles, Global Head of Biostatistics at Immunic
  • Abstract ID: 11244
  • Poster Board Label: LBA14
  • Session Date: Thursday, May 28, 2026
  • Session Time: 5:00-7:00 pm ET
  • Location: Exhibit Hall

This late-breaking poster introduces a novel unified endpoint, Confirmed Disability Change (CDC), designed to capture both confirmed disability worsening (CDW) and confirmed disability improvement (CDI) within a single statistical framework. Three complementary statistical approaches, including ordinal categorical analysis, time-to-event modeling and Markov state change modeling, were applied post-hoc to data from the phase 2 CALLIPER trial in PMS. Across these models, results consistently favored vidofludimus calcium over placebo.

These findings suggest that the CDC approach may provide a more complete view of disability trajectories in PMS than conventional one-direction analyses, particularly for evaluating possible neuroprotective effects. Broader adoption of such an integrated endpoint may improve statistical power in future clinical trials and help better capture treatment benefits for patients with PMS.

  • Poster Title: Effect of Vidofludimus Calcium, a Direct Nurr1 Activator and Selective DHODH Inhibitor, on Patient-Reported Outcomes (PRO) in Progressive MS: Data from Phase 2 CALLIPER Trial
  • Presenting Author: Julie Korich, Ph.D., Senior Medical Director, Medical Affairs at Immunic
  • Abstract ID: 10843
  • Poster Board Label: DMT10
  • Session Date: Thursday, May 28, 2026
  • Session Time: 5:00-7:00 pm ET
  • Location: Exhibit Hall B

This poster presents patient-reported outcomes from the phase 2 CALLIPER trial of vidofludimus calcium in PMS, including measures of severity of depressive thoughts (Patient Health Questionnaire-9, PHQ-9) and overall treatment satisfaction (Treatment Satisfaction Questionnaire for Medication), collected over the treatment period of up to 120 weeks.

Analyses using a mixed model repeated measures (MMRM) approach showed that changes in PHQ-9 scores were similar between vidofludimus calcium and placebo across all assessed timepoints, including weeks 48, 72 and 120. At week 48, PHQ-9 scores numerically improved in both groups (vidofludimus calcium: -0.786 vs. placebo: -0.347), with a similar pattern observed at week 72 (vidofludimus calcium:

-0.568 vs. placebo: -0.609) and week 120 (vidofludimus calcium: -1.777 vs. placebo: -0.525). There was no indication of worsening depressive or suicidal thoughts with vidofludimus calcium (n=235) as compared to placebo (n=232) through 120 weeks.

Patient-reported treatment effectiveness numerically favored vidofludimus calcium over placebo, particularly in perceived effectiveness at both week 48 (77.51 vs. 72.88) and week 120 (84.69 vs. 79.20), while side effect burden remained comparable between the treatment groups at both timepoints (97.65 vs. 97.70 at week 48 and 99.44 vs. 99.36 at week 120). Although exploratory in nature, these findings support a favorable patient-reported profile for vidofludimus calcium over two years.

  • Poster Title: Safety and Tolerability of Vidofludimus Calcium, a Direct Nurr1 Activator and Selective DHODH Inhibitor: Data from Phase 2 CALLIPER Trial
  • Presenting Author: Alex Lublin, Ph.D., Senior Medical Director, Medical Affairs at Immunic

This poster provides an overview of safety and tolerability data from the phase 2 CALLIPER trial of vidofludimus calcium in PMS, based on 467 patients treated for up to 120 weeks.

The overall incidence of treatment-emergent adverse events (TEAEs) was comparable between vidofludimus calcium (69.4%) and placebo (68.5%). The most commonly reported events, including urinary tract infection, headache and back pain, occurred at similar or lower rates in the vidofludimus calcium arm compared to placebo. TEAEs leading to discontinuation were identical at 2.6% in both groups. Liver-related TEAEs were uncommon and similar between vidofludimus calcium and placebo (5.2% vs. 5.5%), with no cases meeting Hy's law criteria. Serious adverse events were observed at low and comparable rates between groups (8.1% vs. 6.5%). Rates of infections and infestations as well as renal or urinary events were also similar between groups.

The collective data set shows a similar overall adverse events profile between vidofludimus calcium and placebo. These results are consistent with previous clinical experience and support the favorable safety and tolerability profile of vidofludimus calcium in patients with PMS.
