Immunic, Inc. Announces First Patients Dosed in its Phase 2, CALVID-1 Clinical Trial of IMU-838 in COVID-19

CALVID-1 recently received regulatory allowance from the German health authority, BfArM (Bundesinstitut für Arzneimittel und Medizinprodukte), from the U.S. Food and Drug Administration (FDA) and from regulatory authorities in other European countries involved in the study. It is a prospective, multicenter, randomized, placebo-controlled, double-blind clinical trial in patients with moderate COVID-19, designed to evaluate efficacy, safety and tolerability of IMU-838. Top-line data is expected to be available later this year.

"Dosing of the first patients in our CALVID-1 trial represents a key milestone in advancing our lead asset, IMU-838, as a potential, novel treatment option for COVID-19," stated Daniel Vitt, Ph.D., Chief Executive Officer and President of Immunic. "Moreover, the CALVID-1 trial is an important strategic expansion of our clinical development of IMU-838 and adds another near-term data readout to our pipeline."

Andreas Muehler, M.D., Chief Medical Officer of Immunic, noted, "Backed by strong preclinical data and a unique profile, IMU-838 has the potential to become an important therapy for treating COVID-19. We expect to include approximately 230 hospitalized COVID-19 patients to evaluate IMU-838’s efficacy, safety and tolerability. An efficacy interim analysis is scheduled after approximately 200 patients have been enrolled. If activity is shown in this interim analysis, our goal is to expand into a confirmatory phase 3 trial using an adaptive trial design."

About IMU-838
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 host-based antiviral effect, which is independent with respect to specific virus proteins and their structure. Therefore, DHODH inhibition may be broadly applicable against multiple viruses. 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 COVID-19, relapsing-remitting multiple sclerosis and ulcerative colitis. Furthermore, Immunic’s collaboration partner, the Mayo Clinic, has started an investigator-sponsored proof-of-concept clinical trial testing IMU-838 activity in patients with primary sclerosing cholangitis. To date, IMU-838 has already been tested in about 650 individuals and has shown an attractive pharmacokinetic, safety and tolerability profile.
