I think Leo knows how P is doing from the interim

I think Leo knows how P is doing from the interim analysis. If you look at the placebo arm in Phase 2a, none of 30 patients achieved PASI 75 after six weeks (slide 11). 23 of those 30 patients were IGA 3 (moderate psoriasis). Although we don't know how severe psoriasis patients will react to the placebo drug, I don't expect them to achieve PASI 75 after just six weeks. So if the patient report shows PASI 75 after six weeks, chances are it's from one of the P arms.
