  • Know more about the drug:

The drug had demonstrated in viro and in vitro activity in animals against viral pathogens MERS and SARS which are structurally similar to COVID-19 as they are from the coronavirus family of viruses. The Phase 3 clinical trials was carried out by providing 2 dosing of the drug for 5 or 10 days to COVID-19 patients. It initially had a sample base of 400 patients but soon expanded to 5600 patients. The success rate was recorded at 64.5% for the 5-day treatment and 53.8% for the 10-day treatment. The result also showcased that patients who were treated within 10 days of symptom onset reacted more positively to the drug than those who were treated after 10 days of symptom onset. This drug had previously been tested for treatment of Ebola virus, but was held to be ineffective in that regard. The World Health Organisations conducted investigative trials in different parts of the world like China and Saudi Arabia among many to test the drug as a part of their Solidarity trials initiative.
