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.
