Gilead Sciences said Wednesday preliminary results of a coronavirus drug trial showed at least 50% of patients treated with a 5-day dosage of antiviral drug remdesivir improved and more than half were discharged from the hospital within two weeks.
The clinical trial involved patients with severe cases of Covid-19. The severe study is โsingle-arm,โ meaning it did not evaluate the drug against a control group of patients who didn't receive the drug.
Shares of Gilead were up more than 7% in premarket trading and are now traded up 4%.
The study tracked two groups of patients who were hospitalized with Covid-19. One group received a 5-day treatment of remdesivir, while the other group took the drug for 10 days.
The researchers said more than half of the patients in both treatment groups were discharged from the hospital within 14 days.
They said 64.5% of the patients who received the shorter treatment course were discharged, compared with 53.8% of the group who were treated for 10 days.
Here is Gilead's announcement:
Gilead Sciences Statement on Positive Data Emerging From National Institute of Allergy and Infectious Diseases' Study of Investigational Antiviral Remdesivir for COVID-19
Apr. 29, 2020-- Gilead Sciences. Inc. (Nasdaq: GILD) is aware of positive data emerging from the National Institute of Allergy and Infectious Diseases' (NIAID) study of the investigational antiviral remdesivir for the treatment of COVID-19. We understand that the trial has met its primary endpoint and that NIAID will provide detailed information at an upcoming briefing.
Remdesivir is not yet licensed or approved anywhere globally and has not yet been demonstrated to be safe or effective for the treatment of COVID-19. Gilead will share additional remdesivir data from the company's open-label Phase 3 SIMPLE trial in patients with severe COVID-19 disease shortly. This study will provide information on whether a shorter, 5-day duration of therapy may have similar efficacy and safety as the 10-day treatment course evaluated in the NIAID trial and other ongoing trials. Gilead expects data at the end of May from the second SIMPLE study evaluating the 5- and 10-day dosing durations of remdesivir in patients with moderate COVID-19 disease.
Gilead will continue to discuss with regulatory authorities the growing data set regarding remdesivir as a potential treatment for COVID-19.
