Immunic Completes Enrollment of Its Phase 2 CALLIPER Trial of Vidofludimus Calcium in Progressive Multiple Sclerosis

Rhea-AI Summary

Immunic, Inc. has completed enrollment of its phase 2 CALLIPER trial of vidofludimus calcium in patients with progressive multiple sclerosis. The trial includes 467 patients and is focused on progressive forms of multiple sclerosis. An interim biomarker analysis is expected in the fall of 2023, and full data readout is expected in April 2025.

NEW YORK, Aug. 17, 2023 /PRNewswire/ -- Immunic, Inc. (Nasdaq: IMUX), a biotechnology company developing a clinical pipeline of orally administered, small molecule therapies for chronic inflammatory and autoimmune diseases, today announced the completion of enrollment of its phase 2 CALLIPER trial of lead asset, vidofludimus calcium (IMU-838), in patients with progressive multiple sclerosis (PMS). In total, 467 patients with primary PMS, or active or non-active secondary PMS have been randomized to either 45mg of vidofludimus calcium or placebo. The trial, running concurrently and as a complement to the company's twin phase 3 ENSURE trials in relapsing multiple sclerosis (RMS), is focused on progressive forms of multiple sclerosis (MS) and is designed to corroborate vidofludimus calcium's neuroprotective potential in this patient population.

Anticipated Milestones for the CALLIPER Trial:

• An interim analysis comprising unblinded biomarker data, including serum neurofilament light chain (NfL), is expected to be available in the fall of 2023 and will include data for approximately half of the enrolled patients (225) who have completed a follow-up period of at least 24 weeks of study treatment.
• A top-line data readout of the full 467 patients is now expected in April of 2025.

"Our phase 2 CALLIPER trial is designed to corroborate the neuroprotective potential of vidofludimus calcium in a progressive patient population. Enrollment of the final PMS patient, according to plan, is another important milestone in the clinical development of our lead asset in MS," stated Daniel Vitt, Ph.D., Chief Executive Officer and President of Immunic. "We believe that the data from the CALLIPER trial, along with that from our ENSURE program, in conjunction with vidofludimus calcium's postulated neuroprotective effects as a first-in-class nuclear receptor related 1 (Nurr1) activator as well as its strong safety and tolerability profile shown, to date, may further strengthen the uniqueness of this treatment approach compared to other oral MS medications and result in a highly attractive commercial positioning."

"As reported in May of this year, in preclinical testing, we have discovered strong Nurr1 agonism by vidofludimus calcium. The known characteristics of Nurr1 activation suggest broad therapeutic potential in neurodegenerative pathologies including MS," added Andreas Muehler, M.D., Chief Medical Officer of Immunic. "The neuroprotective properties of vidofludimus calcium were already identified in our phase 2 EMPhASIS trial of vidofludimus calcium in relapsing-remitting MS, by showing an initial signal for prevention of confirmed disability worsening, as reported in November of last year. We look forward to reporting the interim analysis of our CALLIPER trial, expected in the fall of this year, to assess biomarkers that have been shown in third-party research to consistently correlate with disease activity in neurodegenerative disorders."

CALLIPER is an international, multicenter, randomized, double-blind, placebo-controlled phase 2 trial which enrolled 467 patients at more than 70 sites throughout North America as well as Western, Central and Eastern Europe, with patients randomized to either 45 mg daily doses of vidofludimus calcium or placebo. The trial's primary endpoint is the annualized rate of percent brain volume change up to 120 weeks. Key secondary endpoints include the annualized rate of change in whole brain atrophy and time to 24-week confirmed disability progression based on the expanded disability status scale (EDSS).

About Progressive Multiple Sclerosis
Multiple sclerosis (MS) is an autoimmune disease that affects the brain, spinal cord and optic nerve. In MS, myelin, the coating that protects the nerves, is attacked and damaged by the immune system. Thus, MS is considered an immune-mediated demyelinating disease of the central nervous system. Progressive multiple sclerosis (PMS) includes both primary progressive MS (PPMS) and secondary progressive MS (SPMS). PPMS is characterized by steadily worsening neurologic function from the onset of symptoms without initial relapse or remissions. SPMS is identified following an initial relapsing remitting course, after which the disease becomes more steadily progressive, with or without other disease activity present.

About Vidofludimus Calcium (IMU-838)
Vidofludimus calcium is a small molecule investigational drug in development as an oral next-generation treatment option for patients with multiple sclerosis and other chronic inflammatory and autoimmune diseases. The selective immune modulator activates the neuroprotective transcription factor nuclear receptor related 1 (Nurr1), which is associated with direct neuroprotective properties. Additionally, vidofludimus calcium is a known inhibitor of the enzyme dihydroorotate dehydrogenase (DHODH), which is a key enzyme in the metabolism of overactive immune cells and virus-infected cells. This mechanism is associated with the anti-inflammatory and anti-viral effects of vidofludimus calcium. Vidofludimus calcium has been observed to selectively act on hyperactive T and B cells while leaving other immune cells largely unaffected and enabling normal immune system function, e.g., in fighting infections. To date, vidofludimus calcium has been tested in more than 1,400 individuals and has shown an attractive pharmacokinetic, safety and tolerability profile. Vidofludimus calcium is not yet licensed or approved in any country.

About Immunic, Inc.
Immunic, Inc. (Nasdaq: IMUX) is a biotechnology company developing a clinical pipeline of orally administered, small molecule therapies for chronic inflammatory and autoimmune diseases. The company's lead development program, vidofludimus calcium (IMU-838), is currently in phase 3 and phase 2 clinical trials for the treatment of relapsing and progressive multiple sclerosis, respectively, and has shown therapeutic activity in phase 2 clinical trials in patients suffering from relapsing-remitting multiple sclerosis and moderate-to-severe ulcerative colitis. 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). IMU-856, which targets the protein Sirtuin 6 (SIRT6), is intended to restore intestinal barrier function and regenerate bowel epithelium, which could potentially be applicable in numerous gastrointestinal diseases, such as celiac disease, where it is currently in preparations for a phase 2 clinical trial. IMU-381, which currently is in preclinical testing, is a next generation molecule being developed to specifically address the needs of gastrointestinal diseases.
