NEW YORK, Aug. 11, 2026 /PRNewswire/ -- Immunic, Inc. (Nasdaq: IMUX), a late-stage biotechnology company pioneering the development of novel oral therapies for neurologic diseases, today reported financial results for the second quarter ended June 30, 2026, and provided a corporate update.

"During the second quarter, we continued to execute across our late-stage development priorities as we advance toward what we believe will be a transformational period for Immunic," said Erik Lundgren, Chief Executive Officer of Immunic. "As we prepare for the next stage of Immunic's growth, we have continued to strengthen our board and team with world-class multiple sclerosis (MS) experts whose extensive development, medical, regulatory and commercialization expertise will be instrumental as we execute on our clinical strategy and prepare for the potential regulatory filings and commercialization of vidofludimus calcium (IMU-838). Following the successful closing of our oversubscribed private placement financing earlier this year, we are well capitalized to execute on our key strategic priorities. We believe the milestones ahead position Immunic for a significant near-term value inflection for vidofludimus calcium in relapsing MS, while continuing to unlock the substantial long-term opportunity across the broader progressive MS patient population."

Jason Tardio, President and Chief Operating Officer of Immunic, commented, "We remain highly encouraged by the consistent and differentiated profile of vidofludimus calcium, supported by additional data from our Phase 2 CALLIPER trial in progressive MS presented at this year's CMSC Annual Meeting, including favorable safety, tolerability, patient-reported, and exploratory efficacy data. Taken together, these findings reinforce our confidence in the potential of vidofludimus calcium to offer a differentiated benefit/risk profile through its novel dual mechanism of action, combining Nurr1 activation with selective DHODH inhibition. We believe this approach has the potential to deliver meaningful efficacy while maintaining the favorable safety and tolerability profile observed to date, positioning vidofludimus calcium as a potentially important new oral treatment option for people living with MS."

"Our Phase 3 ENSURE trials of vidofludimus calcium in relapsing MS remain on track to report top-line data by the end of 2026," added Michael A. Panzara, M.D., M.P.H., Chief Medical Officer of Immunic. "With regulatory alignment and precedent surrounding the time to first relapse primary endpoint, the path to regulatory submission upon positive trial results is clear. In parallel, we are preparing to initiate our Phase 3 progressive MS trial later this year, reinforcing our commitment to evaluating the potential of vidofludimus calcium for anyone living with MS."

Second Quarter 2026 and Subsequent Highlights

• Ongoing Phase 3 ENSURE Relapsing MS Program: Continued to execute the twin Phase 3 ENSURE-1 and ENSURE-2 trials of vidofludimus calcium in relapsing MS.
• Preparation of Phase 3 Progressive MS Program: Continued preparations for a confirmatory Phase 3 program in progressive MS, building on the Phase 2 CALLIPER trial data.

The new analyses, which included a novel unified confirmed disability change (CDC) endpoint, up to 120 weeks of patient-reported outcomes, and safety and tolerability data, further reinforced the favorable profile of vidofludimus calcium and its potential to address underlying drivers of disability progression in progressive MS.
• Expansions in Management and Board of Directors:
  • Appointment of Erik Lundgren as Chief Executive Officer, effective May 22, 2026, with employment having begun on June 1, 2026.

About Immunic, Inc.
Immunic, Inc. (Nasdaq: IMUX) is a late-stage biotechnology company pioneering the development of novel oral therapies for neurologic diseases. The company's lead development program, vidofludimus calcium (IMU-838), is currently being evaluated in Phase 3 clinical trials for the treatment of relapsing multiple sclerosis, with top-line data expected to be available by the end of 2026. Initiation of an additional Phase 3 clinical trial in progressive MS is expected later in 2026. Vidofludimus calcium has already shown therapeutic potential and a favorable safety and tolerability profile in Phase 2 clinical trials in relapsing-remitting multiple sclerosis, progressive multiple sclerosis and other diseases. 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). The company's development pipeline also includes earlier-stage programs, including IMU-381 and IMU-856, aimed at building a broader therapeutics platform addressing neurodegenerative and autoimmune diseases.
