Planegg-Martinsried, Germany, February 26, 2019 – Immunic AG (Immunic), a privately held clinicalstage biotechnology company, today announced enrollment of the first patient in a phase 2 clinical study of IMU-838 for the treatment of patients with relapsing-remitting multiple sclerosis (RRMS). IMU-838 is an orally available, next-generation selective immune modulator that inhibits the intracellular metabolism of activated immune cells by blocking the enzyme dihydroorotate dehydrogenase (DHODH).
This phase 2 study is an international, multicenter, double-blind, placebo-controlled, randomized, parallel-group trial that is expected to enroll approximately 200 patients in more than 40 centers across four European countries. The study’s primary objective is to evaluate the dose response of 30 mg/day and 45 mg/day of IMU-838, once daily, for the treatment of RRMS based on magnetic resonance imaging (MRI) assessments. Patients enrolled in the trial will have shown disease activity based on clinical evidence of relapse and MRI criteria.
The trial includes a blinded 24-week main treatment period with an optional extended treatment period to evaluate long-term safety and tolerability of IMU-838 that will be unblinded when all patients have completed the main treatment portion and the study database has been locked. The primary endpoint of the study is the cumulative number of combined unique active (CUA) MRI lesions, up to week 24.
Daniel Vitt, Ph.D., Chief Executive Officer of Immunic, stated, “Enrollment of the first patient in this trial as planned and on schedule represents another key milestone for Immunic and demonstrates the ability of our company to effectively execute our drug development strategy. We had already advanced IMU-838 into a phase 2 trial for ulcerative colitis, so we are excited about its clinical testing in this additional patient population. This development further advances our goal of expanding the indications for which IMU-838 shows great promise for patients with chronic inflammatory and autoimmune diseases.”
“The mode of action of IMU-838, DHODH inhibition, is already commercially proven in RRMS, and the safety and tolerability profiles of IMU-838 are well understood. To date, more than 350 individuals have been treated with the active moiety, with no general detrimental effect on bone marrow observed in animal experiments, no increased rate of alopecia or diarrhea, and no increased rate of infections compared with placebo in earlier clinical trials in other indications,” commented Andreas Muehler, MD, Chief Medical Officer of Immunic. “We look forward to carrying out this trial in support of further clinical data showing IMU-838 as a potentially best-in-class, once-daily oral therapy to treat RRMS.”

IMU-838 is an orally available, next-generation selective immune modulator that inhibits the intracellular metabolism of activated immune cells by blocking the enzyme dihydroorotate dehydrogenase (DHODH). IMU-838 acts on activated T and B cells while leaving other immune cells largely unaffected and allows the immune system to stay functioning, e.g. in fighting infections. In previous trials, IMU-838 did not show an increased rate of infections compared to placebo. In addition, DHODH inhibitors such as IMU-838 are known to possess a direct antiviral effect. IMU-838 was successfully tested in two phase 1 clinical trials in 2017 and is currently being tested in phase 2 trials in patients with ulcerative colitis and relapsing-remitting multiple sclerosis. Immunic intends to initiate an additional phase 2 trial in patients with Crohn’s disease later in 2019. Furthermore, Immunic’s collaboration partner, Mayo Clinic, plans to start an investigator-sponsored proof-of-concept clinical trial testing IMU-838 activity in patients with primary sclerosing cholangitis (PSC) in the first quarter of 2019.
