Immunic, Inc. Announces 200 Patients Enrolled in Its Phase 2 CALVID-1 Trial of IMU-838 for the Treatment of Moderate COVID-19, Allowing for Main Phase 2 Efficacy Analysis to Proceed

– Top-Line Data Expected in Q1 2021 –

NEW YORK, November 2, 2020 – Immunic, Inc. (Nasdaq: IMUX),a clinical-stage biopharmaceutical company developing a pipeline of selective oral immunology therapies aimed at treating chronic inflammatory and autoimmune diseases, today announced that the company has enrolled and randomized 200 patients, pre-specified in the protocol as sufficient to perform the main efficacy analysis of the phase 2 part of the CALVID-1 trial for its selective oral DHODH inhibitor, IMU-838, in hospitalized patients with moderate coronavirus disease 2019 (COVID-19). The aim of the CALVID-1 trial is to investigate IMU-838 as an oral treatment option for moderate COVID-19 and to support potential use of IMU-838 as a treatment for current and potential future viral pandemic threats. The trial is being conducted under an investigational new drug application granted by the U.S. Food and Drug Administration using a single global protocol with clinical sites in the United States, Germany and a range of other European countries.

The current part of CALVID-1 is defined as a phase 2 proof-of-activity trial. As per the protocol, approximately 200 patients were to be included in order to perform a main efficacy analysis which will be used, in consultation between Immunic and an Independent Data Monitoring Committee (IDMC), to assess clinical activity of IMU-838 in moderate COVID-19 based on pre-defined criteria. No formal statistical analysis was pre-specified for this main analysis and all endpoints will be analyzed descriptively. Enrollment continues while the analysis is being prepared. Apart from assessing the clinical activity of IMU-838, the main analysis of the phase 2 part of the CALVID-1 trial may also be used for sample size determination, endpoint selection and potential other trial adjustments in order to continue with a confirmatory phase 3 trial, if such continuation is warranted. The final design of the phase 3 portion will be submitted as a protocol amendment to regulatory authorities.

“Enrollment of 200 patients in the phase 2 part of our CALVID-1 trial is another notable achievement for our lead asset, IMU-838, and comes on the heels of the previously announced interim safety results that supported continuation of this trial without modifications,” stated Daniel Vitt, Ph.D., Chief Executive Officer and President of Immunic. “Given the established broad antiviral activity of IMU-838 in multiple virus strains as well as different cell cultures infected with SARS-CoV-2, we look forward to the findings of the main efficacy analysis of the phase 2 part of our CALVID-1 trial, which is expected to be available in the first quarter of 2021, after which we will be able to evaluate whether the program may be expanded into a confirmatory phase 3 trial.”

Andreas Muehler, M.D., Chief Medical Officer of Immunic, added, “We greatly appreciate the strong support we have received from both our clinical investigators and site study teams during such a challenging and unprecedented period. The Immunic team is extremely pleased with the speed at which the trial has enrolled, which is a direct result of the symbiotic partnership we have built with our investigators and local clinical Contract Research Organizations.”

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 ulcerative colitis and COVID-19. 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. 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. IMU-838 is not yet licensed or approved in any country.
