NEW YORK, May 27, 2026 /PRNewswire/ -- Immunic, Inc. (Nasdaq: IMUX), a late-stage biotechnology company pioneering the development of novel oral therapies for neurologic diseases, today announced the appointment of distinguished biopharmaceutical executive Erik Lundgren as Chief Executive Officer, effective May 22, 2026, with employment beginning on June 1, 2026. Mr. Lundgren succeeds Daniel Vitt, Ph.D., who will retain responsibility for scientific strategy and portfolio advancement while remaining a member of Immunic's Board of Directors.

Mr. Lundgren will lead Immunic as the company advances vidofludimus calcium through late-stage clinical development, including the pivotal phase 3 ENSURE program in relapsing multiple sclerosis (RMS) and the planned phase 3 program in primary progressive multiple sclerosis (PPMS), while also preparing for potential new drug application (NDA) filing, regulatory approval and commercialization.

"Immunic has evolved into a global late-stage biotechnology company built around its lead asset, vidofludimus calcium, which we believe represents one of the most compelling and differentiated opportunities in multiple sclerosis (MS) today," stated Michael W. Bonney, Chair of Immunic's Board of Directors. "As we look to our next phase of growth, including the pivotal phase 3 RMS data readout expected by year-end, preparations for NDA filing in this indication and potential commercialization thereafter, Erik's experience will be invaluable. I look forward to working with him as we continue transitioning Immunic toward a commercial-stage neurology company and deliver a potential next-generation treatment option for people living with MS."

"I am truly honored to be joining Immunic at such an exciting and pivotal moment," stated Mr. Lundgren. "Over the past decade, the treatment landscape for MS has advanced meaningfully, broadening what is possible for people living with this complex disease. Yet a large unmet need remains, particularly for treatment options with the potential to slow disability progression and preserve neurological function. Vidofludimus calcium's potential to treat MS by targeting both immunological and neuroprotective pathways, along with a safety and tolerability profile that appears favorable to date, offers a differentiated approach within the MS therapeutic landscape, with the chance to impact both relapsing and progressive forms of the disease. Having spent my career focused on bringing innovative medicines to patients, including those with MS, I believe Immunic is uniquely positioned to advance this important program through late-stage development and potential commercialization. I look forward to working alongside the talented team at Immunic to help realize that vision."

"Erik is highly accomplished and possesses the strategic, operational and commercial know-how needed to steer Immunic at this critical juncture," added Dr. Vitt. "His deep expertise in MS, including his role in helping shape the launch of Ocrevus®, combined with his long tenure and broad experience across Genentech and Roche, will be instrumental as we advance vidofludimus calcium through the pivotal phase 3 ENSURE readout in RMS and continue preparations for our planned phase 3 program in PPMS. As we approach these important milestones and continue our evolution toward becoming a commercial-stage biotechnology company, I am convinced that Erik is the right leader to guide Immunic into its next chapter. I look forward to continuing to support the company's scientific strategy and working alongside Erik and the Board to realize the full potential of our pipeline."

Mr. Lundgren brings nearly two decades of biopharmaceutical experience spanning commercial strategy, product launches, global portfolio leadership, marketing and general management, with particular expertise in MS. He most recently served as Senior Vice President, Commercial Portfolio Organization at Genentech (a member of the Roche Group), where he led and oversaw the commercial strategy across all therapeutic areas of the company's broad portfolio. Prior to this role, he served as General Manager of Roche Czech Republic, where he led full operations and commercial strategy. Earlier, he served as Lifecycle Leader for Huntington's disease within Roche's neuroscience portfolio.

Mr. Lundgren spent more than a decade at Genentech in roles of increasing responsibility, including serving as Senior Marketing Director supporting the launch and commercialization of Ocrevus® (ocrelizumab), a foundational treatment for RMS and PPMS and one of the most successful launches in neurology. He also held commercial leadership roles supporting the launches of oncology medicines, including Kadcyla® (ado-trastuzumab emtansine) and Zelboraf® (vemurafenib), and led various sales teams within Genentech's oncology franchise.

Mr. Lundgren earned his Bachelor of Arts in Public Policy from Duke University and his Master of Business Administration from Harvard Business School.

The Compensation Committee of Immunic's Board of Directors granted Mr. Lundgren an initial equity option to purchase 1,000,000 shares of common stock of the company under the Immunic, Inc. 2026 Inducement Equity Compensation Plan (the "Options"). The Options were granted as an inducement material to Mr. Lundgren's commencement of employment pursuant to NASDAQ Listing Rule 5635(c)(4). The Options will be time vested, with 25% vesting on the one-year anniversary of May 22, 2026 and the remainder vesting on a monthly basis in 36 equal installments.
