Gilead’s COVID-19 treatment doesn’t prevent long-term symptoms, study finds

The first trial to evaluate the long-term effects of remdesivir — Gilead Science’s treatment for COVID-19, and the first one to be approved by the FDA in 2020 — found there was “no convincing evidence of remdesivir benefit” one year after patients were hospitalized with COVID-19, the researchers concluded.

The study included 208 patients hospitalized with COVID-19 in Finland, 181 of whom completed the one-year follow-up survey. Of those, 98 were given remdesivir during hospitalization and 83 were not. The two groups reported similar outcomes: In each, about 1 in 6 respondents said they had not recovered well, and a quarter of them said they had substantial bother from fatigue. The results were published Oct. 18 in Nature.

The FDA approved Gilead’s treatment, which is sold under the brand name Veklury, in 2020. It is intended for COVID-19 patients who are at high risk for severe disease, and “are either hospitalized with COVID-19 or have mild-to-moderate COVID-19,” according to the drugmaker’s website

With the small pool of study participants, the “confidence intervals are wide, including substantial benefit and harm,” meaning more trials are needed to determine the drug’s long-term efficacy, the researchers wrote. 

The World Health Organization conditionally recommends remdesivir for non-severe and severe COVID-19 cases, but not for critical infections.
