Sharks in the pharma supply chains are stockpiling and black-marketing a key life-saving drug for Covid-19, an India Today investigation has found. Remdesivir, produced by America's Gilead Sciences, is touted as the best hope for critically-ill coronavirus patients for its ability to shorten recovery times in clinical trials. Gilead has licensed several drugmakers in India to make its generic versions. India Today's undercover investigation has found that those who need Remdesivir to keep them alive may not be able to afford it because of its excessive pricing on the black market.
