NEW YORK, Feb. 26, 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 financial results for the year ended December 31, 2025, and provided a corporate update.

"The phase 3 ENSURE-1 and ENSURE-2 trials of our lead asset, orally available nuclear receptor-related 1 (Nurr1) activator, vidofludimus calcium (IMU-838) in relapsing multiple sclerosis (RMS) continue to progress, with top-line data expected to be available by the end of 2026," stated Daniel Vitt, Ph.D., Chief Executive Officer of Immunic. "As we continue to advance our multiple sclerosis (MS) program with vidofludimus calcium, we were extremely pleased to have recently announced the successful completion of an oversubscribed private placement of up to $400 million in gross proceeds, with $200 million in upfront gross proceeds. This financing is truly a pivotal milestone for Immunic and positions us to confidently transition into a fully integrated commercial-stage company. The transaction was led by our existing investor BVF Partners L.P. with participation from a group of highly regarded new and other existing investors. This level of commitment reflects growing confidence in our program and reinforces our belief in vidofludimus calcium's potential to address the underlying drivers of MS progression."

"The proceeds from the initial closing are expected to fund our operations through the ENSURE top-line data and our planned RMS New Drug Application (NDA) submission in the United States in mid-2027, with a targeted potential regulatory approval date in 2028," continued Dr. Vitt. "They also support preparations for the potential launch of vidofludimus calcium in RMS, including expansion of our medical and commercial infrastructure. Additionally, based on the totality of the phase 2 CALLIPER trial data in progressive MS, which showed not only substantial and medically relevant reductions for vidofludimus calcium in delaying 24-week confirmed disability progression but also statistically significant 24-week confirmed disability improvement, while confirming the drug's favorable safety and tolerability profile already observed in previous clinical trials, we plan to initiate a confirmatory phase 3 program in primary progressive multiple sclerosis (PPMS) later this year as well."

Jason Tardio, President and Chief Operating Officer of Immunic, added, "This is an exciting moment for Immunic and for individuals living with MS, as we believe that vidofludimus calcium could represent a potentially transformative approach to disease modification. Current oral therapies for RMS mainly control inflammation and relapses, often have complex safety and tolerability issues and do not adequately address the neurodegenerative processes driving disability progression and long-term disability. In contrast, vidofludimus calcium is uniquely designed to provide direct neuroprotective effects by enhancing neuronal survival and function through Nurr1 activation, while reducing new inflammatory damage via selective DHODH inhibition. This first-in-class mechanism has the potential to address the two key biological drivers of disability progression—relapse-associated worsening (RAW) and progression independent of relapse activity (PIRA)—potentially offering advantages over currently available therapies that primarily focus on inflammatory relapses. As such, we believe vidofludimus calcium may achieve a best-in-class benefit-risk profile and, therefore, could represent a large commercial opportunity in the global MS market, which is projected to reach over $30 billion by the early 2030s."

Fourth Quarter 2025 and Subsequent Highlights

• February 2026: Completed an oversubscribed private placement of up to $400 million in gross proceeds, led by existing investor BVF Partners L.P. with participation from Aberdeen Investments, Avidity Partners, Coastlands Capital, EcoR1 Capital, Janus Henderson Investors, OrbiMed, RA Capital Management, TCGX, Trails Edge Capital Partners, Vivo Capital, Woodline Partners LP, and other institutional investors. A total of $200 million in gross proceeds to Immunic was received upon closing on February 17, 2026.
  • Simona Skerjanec, former SVP, Global Head of Neuroscience and Rare Diseases at Roche, elevated to Interim Chairperson of the Board of Directors. Dr. Duane Nash, former Chairman, remains a member of the Board. Thor Nagel, Principal at BVF Partners L.P., appointed to the Board. Plans underway for further Board refreshment to support the company's evolution into a commercial-stage organization. 
  • Initiated search for a new Chief Executive Officer with deep commercial expertise in MS to lead Immunic into its next stage of growth and commercialization. Subsequently, Dr. Vitt will return to his roots and transition to a new senior executive role focused on scientific strategy and portfolio advancement, while remaining on the Board.

• February 2026: Presented additional data from the phase 2 CALLIPER trial of vidofludimus calcium in patients with progressive MS at the ACTRIMS Forum 2026. The findings, presented in two poster presentations, 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 Immunic's belief that vidofludimus calcium has the potential to address underlying mechanisms of disease progression in MS patients.

Anticipated Clinical Milestones

• Vidofludimus calcium in MS:
  • Top-line data from the twin phase 3 ENSURE-1 and ENSURE-2 trials in RMS is expected by the end of 2026. Subsequently, Immunic plans to submit an NDA in the United States in mid-2027, with a targeted potential regulatory approval date in 2028.
  • Initiation of a phase 3 clinical program in PPMS is expected later this year and estimated to take approximately 3.5 to 4 years to complete.

• IMU-856: The company continues preparing for further clinical testing of IMU-856, contingent on financing, licensing or partnering.

Financial and Operating Results

• Research and Development (R&D) Expenses were $82.0 million for the twelve months ended December 31, 2025, as compared to $80.0 million for the twelve months ended December 31, 2024. The $1.9 million increase reflects (i) a $3.9 million increase in external development costs related to the vidofludimus calcium program and (ii) a $1.8 million increase in personnel expenses for R&D. The increase was offset by (i) a $3.0 million decrease in external development costs related to IMU-856 and (ii) a $0.8 million decrease across numerous categories.
  
  
• General and Administrative (G&A) Expenses were $21.2 million for the twelve months ended December 31, 2025, as compared to $18.0 million for the same period ended December 31, 2024. The $3.2 million increase was due to (i) a $1.9 million increase related to personnel expenses, of which $0.3 million was related to non-cash stock compensation, (ii) a $0.8 million increase in legal and consultancy expenses and (iii) a $0.5 million increase related to costs across numerous categories.
  
  
• Interest Income was $1.0 million for the twelve months ended December 31, 2025, as compared to $3.4 million for the twelve months ended December 31, 2024. The $2.4 million decrease was due to a lower average cash balance.
  
  
• In the twelve months ended December 31, 2024, there was a non-cash charge related to the change in value of the tranche rights associated with the January 2024 Financing from January 8, 2024 until March 4, 2024. These tranches were initially classified as a liability, but were reclassified to equity on March 4, 2024, when stockholders approved the increase in the company's authorized shares from 130 million to 500 million shares of common stock and, therefore, the tranche 2 and tranche 3 rights needed to be revalued to fair value upon the reclassification to equity. There was no change in fair value of the tranche rights recognized in the twelve months ended December 31, 2025.
  
  
• Other Income (Expense) was $5.0 million for the twelve months ended December 31, 2025, as compared to ($1.0 million) for the same period ended December 31, 2024. The $6.1 million increase was primarily attributable to (i) $4.8 million of grant income from the German Federal Ministry of Finance, of which $1.0 million was recognized in the first quarter 2025 and $3.8 million was recognized in the fourth quarter 2025, (ii) a $1.7 million expense related to the portion of deal costs from the January 2024 Financing related to the tranche rights that were established at the time of the deal closing in 2024 and (iii) a $0.3 million increase across numerous categories. The increase was offset by a $0.7 million decrease in research and development tax incentives for clinical trials in Australia due to lower clinical trial spend in Australia.
  
  
• Net Loss for the twelve months ended December 31, 2025, was approximately $97.2 million, or $0.62 per basic and diluted share, based on 155,688,030 weighted average common shares outstanding, compared to a net loss of approximately $100.5 million, or $1.00 per basic and diluted share, based on 100,174,766 weighted average common shares outstanding for the same period ended December 31, 2024.
  
  
• Cash and Cash Equivalents as of December 31, 2025 were approximately $15.5 million. With these funds and the approximately $187.0 million net cash proceeds raised in the February 2026 private placement, Immunic expects to be able to fund its operations into late 2027.
