I remain baffled by these conspiracies that big pharma doesn't investigate or hides certain drugs that could cure diseases because of some vaguely defined profit motives or political backstabbing. A version of this nonsense got the trial of the century with Axovant's approach to buying cheap discarded molecules that were totally just cast aside for political reasons before investing in huge, spectacular failures of clinical trials. Do people really think that the profits from a successful treatment for any of these diseases wouldn't outweigh any profits lost for the people that develop them? It's absurd.
