Brilacidin COVID-19 Antiviral Description

Innovation Pharma Brilacidin is a Host Defense Protein mimetic representing a new drug class with antiviral, anti-inflammatory, and anti-bacterial properties.

Brilacidin (PMX-30063) is a synthetic, non-peptidic small molecule that kills pathogens swiftly, significantly reducing drug resistance development. Brilacidin also functions in a robust immunomodulatory capacity, lessening inflammation, and promoting healing. In addition, Brilacidin has the potent ability to inhibit coronaviruses, primarily by disrupting viral integrity and blocking viral entry.

Brilacidin is one of the few drugs targeting COVID-19 tested in human trials for other clinical indications. In addition, laboratory testing at independent laboratories supports Brilacidin’s antiviral ability to safely and potently inhibit SARS-CoV-2 and multiple strains of human coronaviruses. For example, in a human lung cell line against SARS-CoV-2, Brilacidin achieved a Selectivity Index of 426.

Modeled after Host Defense Proteins (HDPs), the “front-line” of defense in the body's innate immune system is a synthetic, non-peptidic small molecule that kills pathogens swiftly, significantly reducing the likelihood of drug resistance developing. Just as importantly, Brilacidin functions in a robust immunomodulatory capacity, lessening inflammation and promoting healing.

On February 9, 2021, the journal Cell Culture published a paper that concluded Brilacidin was shown to exert potent inhibitory effects on SARS-CoV-2 in cell culture by decreasing viral load in different cell types, including ACE2 positive human lung cells, and, importantly, in both the Washington and Italian strains of the coronavirus. Testing of Brilacidin against additional SARS-CoV-2 strains is planned, concluded this paper.

Brilacidin and related compounds are protected under various compositions and use patents. A patent was filed and is pending for HDP-mimetics in the prophylaxis and/or treatment of inflammatory diseases of the gastrointestinal tract. Another patent for compounds for use in the treatment of mucositis has been awarded numerous global protections.

Brilacidin COVID-19 Antiviral History

Innovation Pharma is developing Brilacidin for COVID-19 under Fast Track designation from the U.S. Food and Drug Administration (FDA) and is currently enrolling patients in Phase 2 clinical trial Brilacidin for treatment of moderate-to-severe COVID-19 in hospitalized patients (NCT04784897; updated April 19, 2021).

Innovation Pharma is developing Brilacidin for COVID-19 under Fast Track designation from the U.S. FDA. Upon recently completing a scheduled review of interim safety data from the trial, an independent Data Monitoring Committee recommended increasing the dosing regimen of Brilacidin from 3 days to 5 days of treatment, which may maximize therapeutic benefits and provide a comparison with 5-day remdesivir (Veklury), currently the only FDA-approved treatment for COVID-19.

A non-peer-reviewed study reported on October 30, 2020, Brilacidin Exhibits Potent In Vitro Antiviral Activity Against SARS-CoV-2.

On December 21, 2020, Innovation Pharmaceuticals announce that the U.S. Food and Drug Administrations had approved the Company’s Investigational New Drug (IND) application to initiate a Phase 2 clinical trial.

On April 5, 2021, Leo Ehrlich, CEO at Innovation Pharmaceuticals, stated in a press release, “There is a sense of urgency to develop novel pan-coronavirus therapeutics for COVID-19, particularly given the growing spread of variants worldwide, including P1 and B.1.1.7, which appear to be contributing to cases of infection cropping up in patients who have already been vaccinated. With its unique mechanism of action to directly disrupt the novel coronavirus, we believe Brilacidin possesses the potential to address these worrisome reminders that SARS-CoV-2 isn’t going anywhere. More broadly, Brilacidin’s antiviral potency also appears to extend beyond coronaviruses to other types of viruses, based on independent ongoing laboratory research, further supporting Brilacidin’s broad-spectrum antiviral potential.”

Headquartered in Wakefield, Massachusetts, Innovation Pharmaceuticals Inc. (formerly Cellceutix Corporation) is a publicly-traded biopharmaceutical company dedicated to discovering and advancing innovative medical therapies in dermatology, oncology, anti-inflammatory, antibiotic, and antiviral applications.
