Drug Repurposing for COVID-19

Dr. Jean Bourbeau is leading a new Phase III clinical trial using dapson to target lung inflammation caused by COVID-19.

Dapsone is a decades-old safe and affordable oral antibacterial that has well-recognized anti-inflammatory and immuno-modulatory properties used against malaria, lupus, HIV and many other inflammatory infections. Repurposing drugs could be a quick, safe and cost-effective way to develop new COVID-19 therapies. Dapsone works on the adherence of immune cells called neutrophils to prevent the release of cytokines. Cytokines are proteins produced by white blood cells that help coordinate the body’s immune response.

“By administering the drug as soon as symptoms start, we hope to attenuate the lung inflammation that is the most frequent cause of worsening symptoms and complications requiring hospitalization.”
