NEW YORK, May 13, 2026 /PRNewswire/ -- Immunic, Inc. (Nasdaq: IMUX), a late-stage biotechnology company pioneering the development of novel oral therapies for neurologic diseases, today announced financial results for the first quarter ended March 31, 2026, and provided a corporate update.

"We are fast approaching a highly pivotal juncture, with the anticipated top-line data readout of the twin phase 3 ENSURE trials of our lead asset, orally available nuclear receptor-related 1 (Nurr1) activator, vidofludimus calcium (IMU-838), in relapsing multiple sclerosis (RMS), expected by the end of 2026," stated Daniel Vitt, Ph.D., Chief Executive Officer of Immunic. "In anticipation, we strengthened our leadership team with the recent appointment of Dr. Michael A. Panzara as Chief Medical Officer. Mike brings deep expertise in neurology and a proven track record of advancing multiple sclerosis (MS) therapies through late-stage clinical development and global regulatory approvals. Additionally, we enhanced our Board of Directors with the appointment of Jon Congleton, who has nearly four decades of biopharmaceutical leadership experience. Earlier in the quarter, Simona Skerjanec, M.Pharm, M.B.A., who joined Immunic's Board of Directors in July 2024, has been elevated to interim Chairperson of the Board and Thor Nagel, Principal at BVF Partners L.P., has been appointed as a member of the Board. Together, these key appointments are intended to best position the company for successful execution of our late-stage development priorities and prepare for potential commercialization."

Dr. Vitt continued, "As important, in February, we closed an oversubscribed private placement financing of up to $400 million in gross proceeds, with $200 million received upfront. This highly successful transaction signals investors' continued confidence in Immunic and has provided the resources we need to advance our programs through key milestones and to continue our transition into a commercial-stage company. The initial proceeds are expected to fund our operations through the completion of our phase 3 ENSURE trials in RMS and our planned RMS New Drug Application (NDA) submission in the United States in mid-2027. The funds will also support continued investment in our development organization and launch readiness. At the same time, we remain focused on expanding the opportunity for vidofludimus calcium beyond RMS, which is supported by the growing body of data from our phase 2 CALLIPER trial in progressive MS (PMS) and our plan to initiate a confirmatory phase 3 program in primary progressive MS (PPMS) later this year."

Jason Tardio, President and Chief Operating Officer of Immunic, added, "We believe vidofludimus calcium has the potential to offer a transformative approach to disease modification in MS. Unlike currently available oral therapies that primarily target inflammatory pathways, vidofludimus calcium is designed to deliver both direct neuroprotective effects through Nurr1 activation and anti-inflammatory activity via selective DHODH inhibition. In clinical trials to date, vidofludimus calcium has demonstrated a favorable safety and tolerability profile. Taken together, these attributes may support a compelling benefit-risk profile in the global MS market, which is projected to exceed $30 billion by the early 2030s."

First Quarter 2026 and Subsequent Highlights

• April 2026: Appointed accomplished biopharmaceutical executive Michael A. Panzara, M.D., M.P.H., as Chief Medical Officer, to lead the company's development organization, including clinical development, medical affairs, and regulatory affairs. Dr. Panzara succeeds Andreas Muehler, M.D., M.B.A., who will continue to support the company as a consultant.
• April 2026: Effected 1-for-10 reverse stock split of the outstanding shares of common stock as of April 27, 2026.
• April 2026: Regained compliance with Nasdaq minimum bid price requirement (Rule 5550(a)(2)) for continued listing, following receipt of a written notice on March 27, 2026.
• March 2026: Appointed Jon Congleton, a seasoned biopharmaceutical executive with nearly 40 years of experience spanning drug development, commercialization and corporate leadership, to the Board of Directors.
• March 2026: Announced grant of a key European patent from the European Patent Office (EPO) directed to label-relevant dosing regimens of vidofludimus calcium. The patent is expected to provide protection into 2038 and may be eligible for a Supplementary Protection Certificate (SPC), which could extend market exclusivity potentially into 2043. This patent was previously granted by the United States Patent and Trademark Office (USPTO) in 2023.
• February 2026: Completed an oversubscribed private placement financing 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.
  • Elevated Simona Skerjanec, former SVP, Global Head of Neuroscience and Rare Diseases at Roche, to Interim Chairperson of the Board of Directors. Dr. Duane Nash, former Chairman, remains a member of the Board. Appointed Thor Nagel, Principal at BVF Partners L.P., 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 neurology 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 PMS at the ACTRIMS Forum 2026 in San Diego, California. 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 is estimated to take approximately 3.5 to 4 years to complete.
• IMU-856: The company is currently exploring strategic alternatives for the IMU-856 program and is open to discussing potential financing, licensing or partnering options with interested parties.
