No, you're not following this correctly. Remdesivir was developed more than a decade ago as a Hepatitis-C treatment (didn't work well), and then studied as an Ebola treatment. It takes years to develop a drug, so they are testing available drugs already on the market that have anti-viral or anti-inflammatory effects with the potential to counteract some of the known or hypothesized pathways of the disease. As a FYI, the "cost" (before rebates, discounts, etc.) of an average Hepatitis-C drug is over $50K for about 8-12 weeks of treatment. Peter Maybarduk, a lawyer at the consumer group Public Citizen, called the price “an outrage.” “This is a drug that received at least $70 million in public funding” toward its development, he said. “Remdesivir should be in the public domain.” “The price puts to rest any notion that drug companies will ‘do the right thing’ because it is a pandemic,” Dr. Peter Bach, a health policy expert at Memorial Sloan Kettering Cancer Center in New York said in an email. “The price might have been fine if the company had demonstrated that the treatment saved lives. It didn’t.” I have no idea where you are quoting that from, but it costs $500M to $1B to develop a drug and bring it to market. $72M is a drop in the bucket when it comes to drug development costs, probably about 10% of the total development cost, and they have discounted remdesivir well over 10% for $3200/treatment. Now, if you're referring to funding a study, that's a different story, as you haven't provided a link to whatever you are quoting that from. But drug development is damn expensive, and remdesivir wasn't developed to treat COVID-19.
