With UPS being a mild form of UC because it's only located in the rectum I think BP will jump all over B for UC if P1 UC is successful. 2/3 of patient remission in UPS with B mixed with water is pretty impressive. Now it will be given in full strength directly to the colon with no additive. I don't think BP will require a 2A for UC prior to a deal.
All IMO of course.
