Immunic Reaches Key Milestone in Multiple Sclerosis Trials

Immunic Completes Enrollment in Phase 3 Trials

Immunic, Inc. (NASDAQ: IMUX), a pioneering biotechnology firm, recently reached a significant milestone by completing enrollment for its Phase 3 ENSURE trials, which focus on its lead drug, vidofludimus calcium. These trials target patients living with relapsing multiple sclerosis (RMS) and aim to evaluate the drug's effectiveness, safety, and tolerability. This achievement is pivotal as it brings Immunic closer to developing potential new treatment options for individuals affected by this chronic condition.

The ENSURE Trials Breakdown

The ENSURE program consists of two identical trials, named ENSURE-1 and ENSURE-2. Both trials are multicenter, randomized, and double-blind, focusing on the efficacy of vidofludimus calcium compared to a placebo for RMS patients. The trials are extensive, with over 100 sites participating across 15 countries, demonstrating the scale and commitment behind this clinical endeavor.

In total, the trials have enrolled 2,221 patients, with 1,121 in ENSURE-1 and 1,100 in ENSURE-2. Each participant is allocated to receive either a daily dose of 30 mg of vidofludimus calcium or a placebo. The primary objective is to evaluate the time to the first relapse, assessed over a period of up to 72 weeks, while secondary objectives include measuring changes in confirmed disability and cognitive functions.

CEO's Insights on the Trials

Dr. Daniel Vitt, the CEO of Immunic, expressed excitement about the timely enrollment of participants, noting that this achievement represents a significant step forward in their late-stage program for multiple sclerosis. He highlighted the potential of vidofludimus calcium's unique neuroprotective properties, which are expected to play an essential role in the trials' outcomes. If successful, this drug could redefine treatment options in the oral MS therapy market, combining safety, tolerability, and neuroprotective benefits.

Progress in the CALLIPER Trial

In addition to the ongoing ENSURE trials, Immunic shared promising data from the Phase 2 CALLIPER trial focusing on progressive MS. This data supports the previous findings that vidofludimus calcium can significantly reduce the relative risk of confirmed disability worsening, underscoring its potential as a neuroprotective therapy.

With a total of 467 patients participating in the trial, results indicate a 24% reduction in confirmed disability worsening in those treated with vidofludimus calcium compared to placebo. Notably, patients with different subtypes of MS showed varying degrees of improvement, with primary progressive MS patients experiencing a 33% reduction in disability worsening.

Deep Dive into the CALLIPER Data

The secondary endpoint examining the time to confirmed disability worsening indicated further positive outcomes. Among patients without gadolinium-enhancing lesions, a 34% reduction in confirmed disability worsening was observed. This suggests that even patients not currently benefiting from conventional therapies may gain advantages from vidofludimus calcium.

Dr. Vitt further articulated that the consistent results across different patient populations reinforced the neuroprotective effects of vidofludimus calcium, positioning it as a promising candidate for future regulatory studies in progressive MS.

About Vidofludimus Calcium and Its Mechanism

Vidofludimus calcium is an oral investigational drug targeting the complexities of chronic inflammatory and autoimmune diseases, particularly multiple sclerosis. Its first-in-class mechanism involves dual actions that not only protect neurons but also exhibit anti-inflammatory effects. This is achieved through its action on the nuclear receptor-related 1 (Nurr1), enhancing neuroprotection while also inhibiting dihydroorotate dehydrogenase (DHODH), a crucial enzyme in the inflammatory pathway.

This multifaceted approach positions vidofludimus calcium as a promising treatment within the landscape of multiple sclerosis therapies and encourages further exploration of its efficacy across various stages of the disease.

About Immunic, Inc.

Immunic, Inc. (NASDAQ: IMUX) specializes in developing innovative, orally administered small molecule therapies targeting chronic inflammatory and autoimmune diseases. With its leading drug, vidofludimus calcium, in advanced stages of clinical trials, the company is poised to revolutionize treatment protocols for multiple sclerosis, with data expected by the end of 2026.
