This portfolio of patents also covers the Company's lead development candidate IMC-1, a synergistic, fixed dose combination of famciclovir and celecoxib, which is in Phase 2b development for the treatment of fibromyalgia.

"We are pleased to expand our substantial intellectual property portfolio with a new patent for an additional proprietary antiviral combination therapy," stated Greg Duncan, Chairman and Chief Executive Officer. "In the context of increasing recognition in the scientific community of the potential role of activated viruses in triggering a wide range of conditions, Virios is actively exploring new disease targets as a complement to our ongoing fibromyalgia Phase 2b program."

About Virios Therapeutics

Virios Therapeutics VIRI is a clinical-stage biotechnology company focused on advancing novel, combination antiviral therapies to treat debilitating chronic diseases, such as fibromyalgia ("FM"). Immune responses related to the activation of tissue resident Herpes Simplex Virus-1 ("HSV-1") have been postulated as a potential root cause triggering and/or sustaining chronic illnesses such as FM, irritable bowel syndrome ("IBS"), chronic fatigue syndrome and other functional somatic syndromes, all of which are characterized by waxing and waning symptoms with no obvious etiology. Our lead development candidate ("IMC-1") is a novel, proprietary, fixed dose combination of famciclovir and celecoxib designed to synergistically suppress HSV-1 replication, with the end goal of reducing virally promoted disease symptoms.

Evidence of IMC-1's efficacy on a broad spectrum of FM outcome measures was previously demonstrated in a Phase 2a clinical trial. These trial results are suggestive that IMC-1 may represent a new and novel treatment for fibromyalgia. IMC-1 has been granted fast track designation by the FDA and is currently being tested in a multi-center, randomized, double-blind, placebo-controlled Phase 2b trial ("FORTRESS") designed to set the stage for registrational studies. The company is led by an executive team highly experienced in the successful development and commercialization of novel therapies. For more information, please visit www.virios.com.
