Immunic, Inc. Announces Completion of Enrollment of its Phase 2 CALDOSE-1 Trial of IMU-838 in Moderate-to-Severe Ulcerative Colitis

NEW YORK, Oct. 28, 2021 /PRNewswire/ -- Immunic, Inc. (Nasdaq: IMUX), a clinical-stage biopharmaceutical company focused on developing best-in-class, oral therapies for the treatment of chronic inflammatory and autoimmune diseases, today announced that the final patient has been enrolled and randomized in its phase 2 CALDOSE-1 trial of lead asset, IMU-838, the company's selective oral DHODH inhibitor, in patients with moderate-to-severe ulcerative colitis (UC). Top-line data for the induction phase is expected to be available in the second quarter of 2022.

"Enrollment of the last patient in our CALDOSE-1 trial brings us one step further in the clinical development of IMU-838 as a potential treatment for UC patients," stated Daniel Vitt, Ph.D., Chief Executive Officer and President of Immunic. "Backed by promising results from the phase 2a ENTRANCE trial performed in UC and Crohn's disease and the interim analysis of the CALDOSE-1 trial published in September 2019, along with IMU-838's already established, strong safety and tolerability profile, we believe that the drug could become a preferred oral treatment option for patients suffering from UC and looking for a convenient treatment option before being escalated to biologics. We look forward to obtaining the unblinded top-line data in the second quarter of next year."

The phase 2 CALDOSE-1 trial is a multicenter, randomized, double-blind, placebo-controlled, dose-finding study being conducted at more than 100 sites in 19 countries, including the United States and Western, Central and Eastern Europe. It is designed to evaluate the efficacy and safety of IMU-838 in patients with UC and includes a blinded induction and maintenance phase, with an option for open-label treatment extension. At the completion of patient recruitment, the trial has randomized a total of 263 patients into four arms: three active dosing arms of 10 mg, 30 mg and 45 mg, as well as placebo. The trial's primary endpoint comprises a composite of a patient-reported outcome and endoscopy-assessed outcome, both evaluated following ten weeks of induction treatment with IMU-838 or placebo. The assessment of endoscopy results is performed by an independent, central reader.

In September 2019, Immunic reported positive results from an interim dosing analysis in the CALDOSE-1 trial which showed that the lowest, 10 mg dose was not likely ineffective, that the highest, 45 mg dose was not intolerable and that no safety signal was identified for any of the trial's three doses. As a result, the trial continued with all three dosing arms.

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 a phase 2 trial in patients with ulcerative colitis. In the third quarter of 2020, the company reported positive results from its phase 2 EMPhASIS trial of IMU-838 in relapsing-remitting multiple sclerosis, achieving both primary and key secondary endpoints with high statistical significance. In the first quarter of 2021, Immunic announced that IMU-838 showed evidence of clinical activity in its phase 2 CALVID-1 trial in hospitalized patients with moderate COVID-19. Also, in the first quarter of 2021, the company reported positive top-line data from an investigator-sponsored phase 2 proof-of-concept clinical trial of IMU-838 in primary sclerosing cholangitis which was conducted in collaboration with Mayo Clinic. To date, IMU-838 has been tested in more than 800 individuals and has shown an attractive pharmacokinetic, safety and tolerability profile. IMU-838 is not yet licensed or approved in any country.
