The more time passes without a PR, the more unlikely it will be they are seeing promising results. But I do trust Dr Patterson's judgement here, since he was spot on with the MOA in cancer... And we still have the Phase 2 trial with milder/ more moderate cases, if it shouldn't work out with sicker patients.
As to possible leaks and SP: in my - very limited experience - there are some stocks, where information (like BO offers, trial results) leak, some where they don't leak at all. To which category CYDY belongs, well, I'll leave that question open...
