Gilead’s Remdesivir shows exceptional promise in the treatment of severely ill COVID-19 patients


''Certainly, Remdesivir appears to have come a full circle.''

Hot on the heels of the disappointing clinical trial from China in patients treated with Remdesivir as reported  in the journal Lancet, comes superbly encouraging results from a trial sponsored by the United States National Institute of Allergy and Infectious Diseases (NIAID).

In the NIAD trial, over a thousand hospitalized patients with severe COVID-19 were randomly chosen to receive either Remdesivir or a placebo. Those who received Remdesivir recovered faster than those who received the placebo (dummy) showing 31% faster time to recovery. Remdesivir also increased survival, with a mortality rate of 8% for those who received the drug and 11.6% for those on the placebo.

The Chinese trial was small, and comprised of 237 severe COVID-19 hospitalised patients who randomly received either Remdesivir or a placebo. Although the drug showed a good safety profile, Remdesivir treatment did not cause significant clinical or antiviral effects. However, interestingly the study showed that patients receiving Remdesivir had a numerically faster time to clinical improvement than those receiving placebo, though not statistically significant.

Earlier in February of this year, researchers in Wuhan had shown that Remdesivir and another drug chloroquine are highly effective in cell culture models of 2019 nCOV  the virus that causes COVID-19. In their paper, they had made a strong case for the testing of these drugs in patients saying  Since these compounds have been used in human patients with a safety track record and shown to be effective against various ailments, we suggest that they should be assessed in human patients suffering from the novel coronavirus disease.” Certainly, Remdesivir appears to have come a full circle.

Remdesivir which began its life in Gilead Sciences under the leadership of the Czechoslovakia born Tomáš Cihlář as a treatment for Ebola virus disease and Marburg virus infections, has now proved its mettle against COVID-19. Though not a  completed cure for COVID-19, until a better drug arrives Remdesivir may well be the gold standard in the  treatment of COVID-19.
