NEW YORK, Aug. 3, 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 financial results for the second quarter ended June 30, 2023, and provided a corporate update.

"During the second quarter, we reported important clinical and preclinical data from our two, lead pipeline programs, including the most advanced drug candidate, vidofludimus calcium (IMU-838), as well as IMU-856," stated Daniel Vitt, Ph.D., Chief Executive Officer and President of Immunic. "Importantly, we announced publication, in the peer-reviewed Journal of Medicinal Chemistry, of preclinical evidence showing that vidofludimus calcium acts as a potent nuclear receptor related 1 (Nurr1) activator, which may be associated with both its hypothesized neuroprotective effects and the reduced disability-worsening events observed in multiple sclerosis (MS) patients. In the fall of this year, we expect to report an interim biomarker analysis of our phase 2 CALLIPER trial in progressive MS, designed to corroborate the neuroprotective potential of vidofludimus calcium, which could become a distinguishing factor in the MS market. Based on the substantial clinical activity seen thus far, along with the already known favorable safety and tolerability profile, we remain confident that vidofludimus calcium can potentially be a unique therapeutic approach for managing the multifaceted pathophysiology of MS."

Dr. Vitt continued, "In May, we reported stronger than expected positive results from the part C portion of our phase 1 clinical trial of IMU-856 in patients with celiac disease, showing the first clinical evidence of its ability, as observed preclinically, to regenerate the gut wall. In particular, the phase 1b data showed that IMU-856 was effective compared to placebo in improving four crucial aspects of celiac disease: histology, disease symptoms, biomarkers and nutrient absorption. This was followed by our announcement, at Digestive Disease Week, of the molecular mode of action of IMU-856 as a potent modulator of Sirtuin 6 (SIRT6), which works to restore and regenerate the architecture of the intestinal wall. As a result, we now have clinical evidence to suggest IMU-856's activity and its potential to treat various gastrointestinal disorders with a novel therapeutic approach. Based on these findings, preparations for a phase 2 clinical trial in ongoing active celiac disease (OACD) are currently underway."

"The maintenance phase of our CALDOSE-1 trial of vidofludimus calcium in moderate-to-severe ulcerative colitis (UC) patients, announced during the quarter, delivered very promising results, demonstrating statistically significant activity in comparison to placebo. Moreover, this data reconfirmed the excellent safety and tolerability profile for vidofludimus calcium found in prior trials," concluded Dr. Vitt.

Second Quarter 2023 and Subsequent Highlights

• July 2023: Hosted a virtual celiac disease expert roundtable to discuss the substantial unmet medical need for new therapeutic solutions. Immunic's management also provided an overview of the company's IMU-856 program, including the recently announced, positive phase 1b trial results in celiac disease patients.
• May 2023: Published preclinical data in the peer-reviewed, high impact Journal of Medicinal Chemistry, confirming that vidofludimus calcium acts as a potent Nurr1 activator, in addition to its known mode of action as a dihydroorotate dehydrogenase (DHODH) inhibitor, in a paper entitled, "Development of a potent Nurr1 agonist tool for in vivo applications." Data showed that activation of Nurr1 could be responsible for the drug's postulated neuroprotective effects and may contribute to the previously reported reduction of confirmed disability worsening events in MS patients.
• May 2023: Presented clinical and preclinical data for IMU-856, including, for the first time, its molecular mode of action as a highly selective and potent small molecule modulator of SIRT6, a protein which serves as a transcriptional regulator of intestinal barrier function and regeneration of bowel epithelium, in a virtual e-poster at Digestive Disease Week (DDW) 2023.
• May 2023: Announced positive results from the part C portion of the phase 1 clinical trial of IMU-856 in patients with celiac disease. Data demonstrated positive effects for IMU-856 over placebo in four key dimensions of celiac disease pathophysiology: protection of the gut architecture, improvement of patients' symptoms, biomarker response and enhancement of nutrient absorption. IMU-856 was also observed to be safe and well-tolerated in this trial. Immunic believes this data provides initial clinical proof-of-concept for an entirely new therapeutic approach to gastrointestinal disorders by promoting regeneration of bowel architecture. The data also provides first clinical evidence that IMU-856's ability, observed in preclinical studies, to re-establish proper gut cell renewal, translates into clinical benefits for patients with celiac disease. Most importantly, the observed protection of intestinal villi from gluten-induced destruction, independent of targeting immune mechanisms involved specifically in celiac disease, appears to be unique among proposed therapeutic approaches and may be applicable to other gastrointestinal disorders.
• April 2023: Strengthened Board of Directors with the addition of Richard Rudick, M.D., a thought-leader in multiple sclerosis with decades of experience in the clinic, academia and industry, effective April 26, 2023. Also announced that Vincent Ossipow, Ph.D., would step down from the Board, effective June 28, 2023.
• April 2023: Reported positive data from the maintenance phase of the phase 2b CALDOSE-1 trial of vidofludimus calcium in patients with moderate-to-severe ulcerative colitis. Data showed a dose-linear increase in clinical remission compared to placebo at week 50. An exploratory statistical analysis confirmed the 30 mg dose of vidofludimus calcium to be statistically superior (p=0.0358) in achieving clinical remission at week 50, with a 33.7% absolute improvement over placebo. Moreover, a dose-linear increase in endoscopic healing was observed, with the 30 mg dose of vidofludimus calcium being associated with a 37.8% absolute improvement over placebo while also achieving statistical significance in an exploratory statistical analysis (p=0.0259). Administration of vidofludimus calcium was observed to be safe and well-tolerated.

Anticipated Clinical Milestones

• Vidofludimus calcium in MS: Data from the interim analysis of the phase 2 CALLIPER trial of vidofludimus calcium in progressive MS, previously guided for the second half of 2023, is now expected to be available in the fall of 2023. The top-line data read-out for the trial is expected at the end of 2024. Data from the interim analysis of the ENSURE program is expected in late 2024, with the read-out of the first of the ENSURE trials at the end of 2025.
• IMU-856 in celiac disease: Based on the positive data from the phase 1b clinical trial, testing IMU-856 in celiac disease patients during periods of gluten-free diet and gluten challenge, the company is actively preparing for clinical phase 2 testing of IMU-856 in OACD patients.

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.
