Phase 2 clinical trial could begin immediately for clofazimine, an FDA-approved drug on WHO’s List of Essential Medicines.
A Nature study authored by scientists at Sanford Burnham Prebys Medical Discovery Institute and the University of Hong Kong shows that the leprosy drug clofazimine, which is FDA approved and on the World Health Organization’s List of Essential Medicines, exhibits potent antiviral activities against SARS-CoV-2 and prevents the exaggerated inflammatory response associated with severe COVID-19. Based on these findings, a Phase 2 study evaluating clofazimine as an at-home treatment for COVID-19 could begin immediately.
“Clofazimine is an ideal candidate for a COVID-19 treatment. It is safe, affordable, easy to make, taken as a pill and can be made globally available,” says co-senior author Sumit Chanda, Ph.D., professor and director of the Immunity and Pathogenesis Program at Sanford Burnham Prebys. “We hope to test clofazimine in a Phase 2 clinical trial as soon as possible for people who test positive for COVID-19 but are not hospitalized. Since there is currently no outpatient treatment available for these individuals, clofazimine may help reduce the impact of the disease, which is particularly important now as we see new variants of the virus emerge and against which the current vaccines appear less efficacious.”
