Drug Pipeline 


Company: Gilead Sciences

Developed by Gilead Sciences to treat the Ebola virus. Provided to physicians and entered clinical trials based on success against other coronavirus infections. According to Bloomberg, the FDA began to move at “lightning speed” to approve remdesivir for treatment after successful trial results. On May 1, the FDA approved the drug for emergency treatment of hospitalized COVID-19 patients. Japan approved remdesivir for treatment of severe COVID-19 patients on May 7.

After previous April claims of drug efficacy, the National Institute of Allergy and Infectious Diseases released a study on May 22 including evidence that remdesivir shortened recovery time from 15 days to 11 days in hospitalized patients.

Remdesivir has not yet received formal approval by the FDA (the May emergency clearance does not count as formal approval).

Gilead also posted an informational tool to help interested people keep track of the company’s COVID-19 clinical trials program.
