I don't think you should be downvoted for expressing skepticism. I'm not going to address the details here, besides to say, I'm talking about something else.

You can read their current study, its primary endpoint is severely treatment resistant GI symptoms, not "autism". That means they are trying to get a liquid FMT with two hero laxative doses per day approved for ASD kids who have failed two other standard of care GI treatments.

But then why not get it approved for adults without ASD? It's a simple question. As you are not very familiar with the therapeutics startup business, you wouldn't know that it's all about commercialization. They are gambling that parents will buy this drug anyway, for its secondary endpoint, which is supposed to be "less disobedient behavior while ASD" (my characterization of the evaluation they receive).

Look... parents can also punch their kids, and I'm sure it'll modify their behavior. Do you see? It's not complicated, there's no conspiracy, there's barely any science.
