My guess regarding why they have a stockpile of this drug is that they were hoping to be able to sell it for ebola, for which it's ineffective, and have subsequently been trying to figure out how to sell it. Here, they're able to get clinical trial information (and lots of goodwill) with a potentially small marginal expenditure. It's also not entirely clear what it means to provide the drugs "at no cost" (later on it says "no charge", but in a separate sentence), nor is it clear how long this promise will last.
