Revive Therapeutics Updates on Bucillamine for Nerve Agent Exposure and Viral Infections

Revive Therapeutics Ltd., a specialty life sciences firm based in Toronto, has announced a significant update on its ongoing research into Bucillamine as a potential therapy for nerve agent exposure. This research is being conducted in collaboration with Defence R&D Canada – Suffield Research Centre (DRDC), an agency under the Canadian Department of National Defence. The study is focused on exploring pharmacological compounds, including Bucillamine, that might alleviate brain injuries caused by nerve agents. The research is advancing well and is expected to be concluded by October 2024.

Bucillamine has been used for over three decades in Japan and South Korea for treating rheumatoid arthritis and is known for its safety. The compound is a derivative of cysteine and has shown to be significantly more potent than N-acetyl-L-cysteine (NAC) in donating thiols, which are essential for boosting antioxidant activity in cells. This property makes Bucillamine a promising candidate for mitigating the effects of nerve agents and potentially treating other conditions such as organophosphate pesticide poisoning.

The outcome of this study will be crucial in deciding the next steps for further investigations aimed at securing FDA and Health Canada approvals for Bucillamine's use in treating nerve agent exposure. Additionally, the study explores Bucillamine's potential in addressing viral infections, notably monkeypox (Mpox). In 2023, the World Health Organization highlighted that severe Mpox cases could lead to various inflammatory conditions, including inflammation of the brain and heart.

A 2022 study indicated that antioxidants might play a role in alleviating the effects of viral infections or reducing viral replication. Antioxidants such as NAC, butylated hydroxyanisole, and Terameprocol were suggested to potentially ease severe Mpox symptoms. NAC, in particular, has shown to significantly reduce clinical symptoms in respiratory viral infections by increasing the antioxidant activity of cellular glutathione. Given Bucillamine's superior thiol-donating capability compared to NAC, it is considered a strong candidate for treating or alleviating symptoms related to Mpox infection.

Revive Therapeutics has made it clear that it is not claiming Bucillamine can treat or cure Mpox or other infectious diseases at this stage. The company is committed to rigorous research and regulatory processes to validate the efficacy and safety of its products.

Revive Therapeutics Ltd. is primarily engaged in the development of therapies and diagnostics for infectious diseases, medical countermeasures, and rare disorders. The company emphasizes leveraging various regulatory incentives provided by the FDA, such as Emergency Use Authorization, Orphan Drug, Fast Track, and Breakthrough Therapy designations. Its current focus includes exploring Bucillamine's potential for treating nerve agent exposure and long COVID. Additionally, Revive is advancing the development of Psilocybin-based therapeutics through several programs.

Revive Therapeutics is dedicated to advancing its drug development efforts to address significant unmet medical needs. The company’s research initiatives are aimed at providing new therapeutic options for severe health conditions and enhancing the overall healthcare landscape.
