It's important to note that all these companies, having no previous experience, vastly underestimate the time clinical research takes, and therefore their ETAs are not accurate at all.
But the fact is there are more treatments in clinical research than ever before, and many of them are really close.
As for this one, keep in mind that topical JAK inhibitors work primarily by activating the WNT pathway. Samumed is conducting a Phase 3 trial for a topical that uses the same mechanism. Aclaris may decide to drop this because a similar product is closer to market.
