Immunic Presents Data From Phase 1b Clinical Trial of IMU-856 in Celiac Disease at the United European Gastroenterology Week 2023

NEW YORK, Oct. 15, 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 presentation of data from the company's phase 1b clinical trial of IMU-856, an orally available and systemically acting small molecule modulator that targets SIRT6 (Sirtuin 6), in patients with celiac disease in a moderated poster session at the United European Gastroenterology Week (UEGW) 2023, taking place October 14-17 in Copenhagen.

In this phase 1b, double-blind, randomized, placebo-controlled trial in patients with celiac disease, IMU‑856 showed positive effects over placebo in four key dimensions of clinical outcome: protection of the gut architecture, improvement of patients' symptoms, biomarker response and enhancement of nutrient absorption. IMU-856 was also found to be safe and well-tolerated with a benign adverse event profile and with pharmacokinetics that allow once-daily dosing. There were no systematic clinically relevant findings relative to safety and tolerability, as assessed by physical examination, clinical laboratory tests, vital signs, and 12-lead electrocardiograms.

"We were delighted to hear that, according to the UEGW, our IMU-856 poster was selected as one of the best among the abstracts submitted," stated Daniel Vitt, Ph.D., Chief Executive Officer and President of Immunic. "In our phase 1b clinical trial, IMU-856 showed the first clinical signals of its potential ability to restore a healthy gut by renewal of the gut wall in patients with celiac disease. These stronger than expected results across histology, disease symptoms, biomarkers and nutrient absorption, along with the drug's clean safety and tolerability profile, may set the stage for a potential first-in-class, oral celiac disease therapy. IMU-856 may also offer extensive potential beyond celiac disease in other gastrointestinal diseases with high unmet needs such as ulcerative colitis, Crohn's disease, or irritable bowel syndrome with diarrhea."

About IMU-856

IMU-856 is an orally available and systemically acting small molecule modulator that targets SIRT6 (Sirtuin 6), a protein which serves as a transcriptional regulator of intestinal barrier function and regeneration of bowel epithelium. Based on preclinical data, the compound may represent a unique treatment approach, as the mechanism of action targets the restoration of the intestinal barrier function and bowel wall architecture in patients suffering from gastrointestinal diseases such as celiac disease, inflammatory bowel disease, irritable bowel syndrome with diarrhea and other intestinal barrier function associated diseases. Immunic believes that, because IMU-856 has been shown in preclinical investigations to avoid suppression of immune cells, it may therefore have the potential to maintain immune surveillance for patients during therapy, an important advantage versus immunosuppressive medications. IMU-856 demonstrated positive results in a phase 1b clinical trial in celiac disease patients in four key dimensions of the disease's pathophysiology: histology, disease symptoms, biomarkers and nutrient absorption. Currently, the company is preparing for phase 2 clinical testing in this patient population. IMU-856 is an investigational drug product that has not been approved in any jurisdiction.

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.
