PRIMARYNumber of Participants With Remission Based on Composite Score at Week 52At Week 52
The ontamalimab responder full analysis set (FAS) consisted of all participants in the randomized set who received at least 1 dose of IP in this study and who were previously treated with ontamalimab in the induction studies (SHP647-301 \[NCT03259334\] and SHP647-302 \[NCT03259308\]). As Pre-specified in protocol all efficacy analyses data were collected and analyzed based on ontamalimab responder (i.e ONTA 25mg/ Placebo, ONTA 25mg/ONTA 25mg, ONTA 75mg/Placebo and ONTA 75mg/ONTA 75mg arms only).
