Immunic Receives Notice of Allowance for United States Patent Protecting the Treatment of Relapsing Multiple Sclerosis with Vidofludimus and Its Salts

NEW YORK, Nov. 2, 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 that it has received a Notice of Allowance from the United States Patent and Trademark Office (USPTO) for patent application 17/391,442, entitled, "Treatment of Multiple Sclerosis Comprising DHODH Inhibitors," covering a daily dose of about 10 mg to 45 mg of vidofludimus calcium (IMU-838) and other salt as well as free acid forms for the treatment of relapsing multiple sclerosis (RMS). The claims are expected to provide protection into 2041, unless extended further.

"Allowance of this patent, covering the dose strength of vidofludimus calcium for the treatment of RMS, including the 30 mg dosage used in our ongoing twin phase 3 ENSURE trials, significantly bolsters the multilayered proprietary intellectual property position we have strategically built around our lead, late-stage program for patients with multiple sclerosis," stated Daniel Vitt, Ph.D., Chief Executive Officer and President of Immunic. "Importantly, this patent for the dose strength in RMS patients covers all salt and free acid forms of vidofludimus calcium. We remain committed to protecting the technology around this phase 3 asset, in order to assure extended exclusivity upon potential regulatory approval from the U.S. Food and Drug Administration."

Vidofludimus calcium is covered by several layers of granted patents in the United States, Europe and other jurisdictions around the world. These patents are directed towards composition-of-matter for salt forms of vidofludimus calcium, including the specific salt form used in Immunic's clinical trials, as well as the dose strength used in clinical trials for the treatment of RMS, as reported in this announcement. In the United States, these patents provide protection into 2041, unless extended further. In addition, pending applications are directed towards composition-of-matter of a specific polymorph of vidofludimus calcium and a related method of production of the clinical material; the dosing regimens including those used in clinical trials for the treatment of MS; as well as the use of vidofludimus calcium and other salt as well as free acid forms for treating neurodegenerative diseases. If granted, these applications could provide protection up to 2044, unless extended further. Finally, additional undisclosed patent applications dedicated to strengthening the exclusivity period are currently in process. On top of the patent exclusivity, vidofludimus calcium, as a new chemical entity, should also benefit from regulatory data protection.

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.
