TORONTO, Aug. 28, 2024 (GLOBE NEWSWIRE) -- Revive Therapeutics Ltd. (“Revive” or the “Company”) (OTCQB: RVVTF) (CSE: RVV) (FRANKFURT:31R), a specialty life sciences company focused on the research and development of therapeutics and diagnostics for infectious diseases, medical countermeasures, and rare disorders, announced today an update on the research study evaluating Bucillamine as a potential treatment for nerve agent exposure, in partnership with Defence R&D Canada – Suffield Research Centre (“DRDC”), an agency of the Canadian Department of National Defence. The DRDC is investigating pharmacological compounds, including Bucillamine, that can mitigate nerve agent induced brain injury. The research study is progressing and is expected to be now completed in October 2024.

The results from this research study, if promising, will determine further studies to facilitate FDA and Health Canada approvals for the use of Bucillamine in nerve agents or organophosphate pesticide poisoning, and explore its potential in viral infections, including monkeypox (“Mpox”). In 2023, the World Health Organization released a Mpox fact sheet suggesting that severe cases of Mpox result in a number of conditions including inflammation of the brain, heart, rectum, genital organs and urinary passages.1

A study in 2022 made the link between the administration of antioxidants and the improvement of virus-induced effects or to reduce viral replication yield. The suggestion that strong antioxidants such as N-acetyl-L-cysteine (“NAC”), butylated hydroxyanisole or Terameprocol could have an effect on Mpox viral infection in humans to ease severe symptoms.2 NAC has been shown to significantly attenuate clinical symptoms in respiratory viral infections in animals and humans, primarily via donation of thiols to increase antioxidant activity of cellular glutathione.3-6

Bucillamine (N-(mercapto-2-methylpropionyl)-l-cysteine) has a well-known safety profile and is prescribed in the treatment of rheumatoid arthritis in Japan and South Korea for over 30 years. Bucillamine, a cysteine derivative with two thiol groups, has been shown to be 16 times more potent as a thiol donor in vivo than NAC.7 Thus, Bucillamine may be a candidate for the treatment or alleviation of symptoms related to Mpox infection.

The Company would like to make it clear that it is not making any express or implied claims that its product (Bucillamine) has the ability to treat, eliminate or cure Monkeypox (Mpox) and/or other infectious diseases at this time.
