Overview
This study is designed as a multi-stage Phase 2 study within a Phase 3 study to evaluate the safety, tolerability, pharmacokinetics, dose-exposure relationship, and anti-tumor activity of IDE196 in combination with crizotinib compared to the comparator arm of investigator's choice of treatment (pembrolizumab, ipilimumab + nivolumab, or dacarbazine). The Phase 2a dose optimization stage will evaluate two doses of IDE196 in combination with crizotinib compared to the comparator arm. Participants will be randomized to the three treatment arms. At the point of optimal IDE196 + crizotinib dose selection, the other dose arm will be dropped with discontinuation of enrollment to that arm. Participants receiving the IDE196 dose (in combination with crizotinib) that is not selected, will be offered the choice to remain on the same dose or change to the chosen optimal dose. The optimal dose will be chosen to complete the Phase 2b portion. The Phase 2b part of the study will continue to enroll the chosen combination dose of IDE196 + crizotinib compared with the comparator arm. Participants will be randomized to the two treatment arms. The Phase 3 part of the study will continue to enroll the chosen combination dose of IDE196 + crizotinib compared with the comparator arm. Participants will be randomized to the two treatment arms.
