NEW YORK, May 11, 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 first quarter ended March 31, 2023, and provided a corporate update.

"In the first quarter of 2023, we reported outstanding results from two key clinical programs. First, we reported positive data from the maintenance phase of our phase 2b CALDOSE-1 trial of vidofludimus calcium in patients with moderate-to-severe ulcerative colitis (UC), and, most recently, announced positive results from our phase 1b clinical trial of IMU-856 in patients with celiac disease, which far exceeded our expectations," stated Daniel Vitt, Ph.D., Chief Executive Officer and President of Immunic. "In the phase 1b trial, IMU-856, designed to restore a healthy gut without suppressing the immune system, demonstrated consistent and meaningful improvements over placebo in four key dimensions of celiac disease pathophysiology: histology, disease symptoms, biomarkers and nutrient absorption. The impressive data set provides first clinical proof-of-concept for IMU-856 and demonstrates its potential to treat gastrointestinal diseases with an entirely new therapeutic approach. Based on this data, we are now preparing for a phase 2b clinical trial of IMU-856 in ongoing active celiac disease patients, while also considering further potential clinical applications in other gastrointestinal disorders. Importantly, during a recent presentation at Digestive Disease Week, we unveiled IMU-856's mode of action as a potent modulator of SIRT6 (Sirtuin 6), through which it restores and regenerates bowel wall architecture."

Dr. Vitt continued, "Data from the maintenance phase of our phase 2b CALDOSE-1 trial of vidofludimus calcium in patients with moderate-to-severe UC were also extremely encouraging, as they demonstrated statistically significant activity of vidofludimus calcium as compared to placebo, while confirming the very favorable safety and tolerability profile observed in other trials. Based on this positive outcome, we are exploring a variety of value creating options for the UC program and other inflammatory bowel disease indications."

"Additionally, during the quarter, we continued to progress vidofludimus calcium for the treatment of multiple sclerosis (MS). Our next value inflection point will be a second half 2023 interim biomarker analysis of our phase 2 CALLIPER trial in progressive MS, which is designed to corroborate the neuroprotective potential of vidofludimus calcium and could therefore be an additional differentiator for the drug in the MS market. Based on the strong clinical activity observed thus far and the solidly established safety and tolerability profile, to date, we continue to believe that vidofludimus calcium has the potential to be a unique treatment option targeted to the complex pathophysiology of MS," concluded Dr. Vitt.

First Quarter 2023 and Subsequent Highlights

• May 2023: Presented clinical and preclinical data for IMU-856, including 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 phase 1b clinical trial of IMU-856 in patients with celiac disease. The 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. The data 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., will step down from the Board, effective June 28, 2023, the date of Immunic's 2023 Annual Meeting of Stockholders.
• 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 as 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 and also achieving statistical significance in an exploratory statistical analysis (p=0.0259). Administration of vidofludimus calcium was observed to be safe and well-tolerated.
• February 2023: Announced that Robert J. Fox, M.D., Staff Neurologist, Mellen Center for Multiple Sclerosis, Vice-Chair for Research, Neurologic Institute, Cleveland Clinic, Cleveland, Ohio, presented data from the blinded and open-label extension parts of the phase 2 EMPhASIS trial of vidofludimus calcium in relapsing-remitting MS at the eighth annual Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) Forum 2023.
• February 2023: Hosted a celiac disease R&D webcast. Management was joined by two renowned key opinion leaders, Joseph A. Murray, M.D., from the Mayo Clinic in Rochester and Michael Schumann, M.D., from the Charité Berlin, to discuss the dynamics of this multifactorial, complex autoimmune disease, immune stimulation and its connection to clinical symptoms, the role of the epithelial barrier in the pathogenesis of the disease, current and potential treatment options and the continued unmet medical need for effective therapeutics, which is driving an increased focus within the industry.

Anticipated Clinical Milestones

• Vidofludimus calcium in MS: As previously announced, data from the interim analysis of the phase 2 CALLIPER trial of vidofludimus calcium in progressive MS is expected to be available in the second half of 2023 and top-line data at the end of 2024. Moreover, 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 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 2b testing of IMU-856 in ongoing active celiac disease.

Financial and Operating Results

• Research and Development (R&D) Expenses were $23.0 million for the three months ended March 31, 2023, as compared to $17.4 million for the three months ended March 31, 2022. The $5.5 million increase reflects (i) a $5.8 million increase in external development costs related to the ongoing clinical programs of vidofludimus calcium in relapsing and progressive MS, as well as IMU-856, (ii) a $0.4 million increase in personnel expense in research and development related to an increase in headcount, $0.1 million of which was due to non-cash stock based compensation and (iii) a $0.2 million increase related costs across numerous categories. The increases were partially offset by a decrease of $0.9 million in external development costs related to the phase 2 clinical trial of vidofludimus calcium in ulcerative colitis and the IMU-935 program.
   
• General and Administrative (G&A) Expenses were $4.3 million for the three months ended March 31, 2023, as compared to $4.0 million for the same period ended March 31, 2022. The $0.3 million increase was primarily due to (i) a $0.2 million increase in travel expense and (ii) a $0.3 million increase across numerous categories. The increases were partially offset by a decrease of $0.2 million in non-cash stock based compensation expense.
   
• Other Income was $2.0 million for the three months ended March 31, 2023, as compared to $0.6 million for the same period ended March 31, 2022. The $1.4 million increase was primarily attributable to (i) a $1.1 million research allowance attributable for tax year 2021 from the German Federal Ministry of Finance and (ii) a $0.8 million increase in interest income as a result of higher interest rates. The increase was partially offset by (i) a $0.3 million decrease in foreign exchange gains and (ii) a $0.2 million decrease in research and development tax incentives for clinical trials in Australia as a result of decreased spending on clinical trials in Australia.
   
• Net Loss for the three months ended March 31, 2023, was approximately $25.3 million, or $0.58 per basic and diluted share, based on 43,664,783 weighted average common shares outstanding, compared to a net loss of approximately $20.8 million, or $0.74 per basic and diluted share, based on 28,127,288 weighted average common shares outstanding for the same period ended March 31, 2022.
   
• Cash, Cash Equivalents and Investments as of March 31, 2023 were $97.1 million. With these funds, Immunic expects to be able to fund its operations into the fourth quarter of 2024.
