And if it fails it fails. It's also in trials for Tourette's. The doctor that did the original small study also stutters. Companies don't just put money into trials hoping to find a market somewhere. If it doesn't work it just get's tossed aside. And that's that. They only keep trying with ecopipam because the small scale study showed some effect. If the larger one fails, well it happens. Also plenty of drugs are used for things that researchers had no idea they'd be used for. Nothing inherently wrong with trying to find a use. Just think of minoxidil (a heart drug at first, only rarely used for that now), viagra (same), dutasteride (used for both hair loss and prostate issues), and other drugs that have multiple uses (think antihistamines that make you sleepy). But that's my view as a guy that works in pharma. If a trial is happening, no need to be upset.
