U.S. drugmaker Mylan NV said it had waived its exclusive U.S. distribution rights to its generic version of HIV treatment Kaletra, which is currently being tested against the coronavirus.
The move would make other drugmakers eligible to seek U.S. approval for their generic versions of the drug and boost supply, which would help in case studies find that Kaletra is effective in treating COVID-19, the disease caused by the virus, Mylan said.
Kaletra, a combination HIV treatment sold by AbbVie Inc, has been considered a potential treatment for the virus, although Chinese investigators have reported that it failed to improve outcomes for seriously ill patients.
Mylan said it had restarted its production of malaria treatment hydroxychloroquine sulfate, another drug that has been tried with some success against the coronavirus.
There are currently no approved treatments or preventive vaccines for COVID-19. Most patients are receiving only supportive care such as breathing assistance.
