Saving Primates from Ebola: The Remdesivir Experiment

In the fight against Ebola, scientists are exploring various treatments to save lives. One of these is remdesivir (RDV), a small-molecule antiviral drug. Researchers wanted to find out how effective different doses of RDV could be in protecting rhesus macaques from the deadly Ebola virus (EBOV). They gave the monkeys a single dose of EBOV and then treated them with RDV four days later. The monkeys were fitted with special devices to monitor their health and administer the drug. The study looked at three different doses of RDV: 5/2. 5 mg/kg, 10/5 mg/kg, and 20/10 mg/kg. These doses were given as a loading dose followed by maintenance doses for 11 days. The results were promising. In the group that received the 10/5 mg/kg dose, 7 out of 8 monkeys survived, which was a significant improvement compared to the control group where only 1 out of 7 monkeys survived. This dose also lowered the viral load in the body after just one treatment. All three doses of RDV helped reduce the viral load in the monkeys' bodies after two treatments. Furthermore, the treatment helped improve the clinical symptoms associated with EBOV disease in most of the monkeys. This study shows that remdesivir could be a potential game-changer in the battle against Ebola.
