Long COVID Impacts Up To 30% of COVID-19 Patients
Activation of Dormant Herpes Virus Infections are Hypothesized as a Potential Trigger of Long COVID
Combination Therapy with IMC-2 (valacyclovir and celecoxib) Expands Virios’ Pipeline

Virios Therapeutics, Inc. (Nasdaq: VIRI), a development-stage biotechnology company focused on advancing novel antiviral therapies to treat chronic diseases, including fibromyalgia, announced today a collaboration with the Bateman Horne Center (“BHC”) of Salt Lake City, Utah, to explore the role of combination antiviral therapy in Long COVID, otherwise known as Post-Acute Sequelae of COVID-19 . The Bateman Horne Center is a non-profit, interdisciplinary Center of Excellence advancing the diagnosis and treatment of myalgic encephalomyelitis/chronic fatigue syndrome (“ME/CFS”), fibromyalgia (“FM”), post-viral syndromes, and related comorbidities.

Virios Therapeutics, Inc. is providing BHC with an unrestricted grant for an investigator-sponsored study to explore the therapeutic potential of combination antiviral therapy with Virios’ second development candidate, IMC-2. The study will evaluate changes in common Long COVID symptoms such as fatigue, sleep, attention, pain, autonomic function and anxiety.

“We are pleased to support the Bateman Horne Center, a leading clinical research center in post-viral syndromes, as they study the therapeutic potential of IMC-2 to ease the burden of Long COVID, which is an emerging healthcare crisis,” said Greg Duncan, Chairman and CEO of Virios Therapeutics Inc.

According to the World Health Organization, COVID-19 has caused more than 373 million infections and more than 5.6 million deaths as of January 2022. Published estimates in the scientific literature suggest that up to 30% will experience Long COVID symptoms. It is estimated that one in three patients who develop Long COVID symptoms were asymptomatic during their acute COVID-19 infection. The mechanisms by which COVID-19 causes lingering symptoms are not well understood. Potential triggers for long term symptoms might include:

Immune-system dysregulation triggered by the COVID-19 virus, including increased production of autoantibodies,
Lingering or re-infection with COVID-19 variants, and
Co-infection or activation of previous viral infections that had become dormant

“Most adults are infected with normally harmless dormant viruses contracted years earlier,” said R. Michael Gendreau, M.D., Ph.D., Chief Medical Officer of Virios Therapeutics. “It is becoming increasingly clear that COVID-19 acutely depresses our immune system, which may allow for reactivation of neurotrophic pathogens such as viruses in the herpes family.”

Virios’ lead antiviral development candidate, orally administered IMC-1, is a novel, proprietary, fixed dose, antiviral therapy combining famciclovir and celecoxib. The ongoing Phase 2b FORTRESS study is a randomized, double-blind evaluation of IMC-1 in patients with FM. The FORTRESS study builds on the statistically significant results from the Company’s previously completed Phase 2a FM clinical study. The 143-patient Phase 2a trial demonstrated that IMC-1 met its primary endpoint of pain reduction and was statistically better tolerated than placebo.

The Company’s dual mechanism antiviral development candidates are designed to synergistically suppress herpes virus activation and replication. The uniqueness of this approach has garnered IMC-1 “fast track” designation by the U.S. Food and Drug Administration (“FDA”), the first of its kind for a new FM development candidate.

About IMC-1 and IMC-2

IMC-1 is a novel, proprietary, fixed dose combination of famciclovir and celecoxib. This dual mechanism antiviral therapy is designed to synergistically suppress herpes virus activation and replication. IMC-1 combines two specific mechanisms of action purposely selected to inhibit herpes virus activation and replication, thereby keeping herpes viruses in a latent (dormant) state or “down-regulating” herpes viruses from a lytic (active) state back to latency. The famciclovir component of IMC-1 inhibits viral DNA polymerase necessary for replication. The celecoxib component of IMC-1 inhibits both cyclooxegenase-2 (“COX-2”) and COX-1 enzymes, used by herpes viruses to accelerate their replication.

IMC-2 is a novel, proprietary combination of valacyclovir and celecoxib that combines two specific and synergistic mechanisms of action, purposely selected to inhibit herpes virus activation and replication. IMC-2 keeps herpes viruses in a latent (dormant) state or “down-regulates” herpes viruses from a lytic (active) state back to latency. The valacyclovir component of IMC-2 inhibits viral DNA polymerase necessary for replication. The celecoxib component of IMC-2 inhibits both COX-2 and COX-1 enzymes, used by herpes viruses to accelerate their replication.

About Virios Therapeutics

Virios Therapeutics (Nasdaq: VIRI) is a development-stage biotechnology company focused on advancing novel antiviral therapies to treat debilitating chronic diseases, such as FM. Immune responses related to the activation of tissue resident herpes have been postulated as a potential root cause triggering and/or sustaining chronic illnesses such as FM, irritable bowel disease (“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 herpes 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.

Virios Therapeutics, Inc. is providing BHC with an unrestricted grant to explore the therapeutic potential of combination antiviral therapy with the Company’s second development candidate, IMC-2, in managing the fatigue, sleep, attention, pain, autonomic function and anxiety associated with Long COVID.

The Company is led by an executive team highly experienced in the successful development and commercialization of novel therapies.
