What was measured

CR rate was defined as percentage of participants with BOR of CR. For participants with metastatic disease, RECIST v1.1 was used to determine BOR. For participants with unresectable locally advanced disease, clinical response criteria were used. RECIST v1.1 Criteria: -CR: Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm \<1 cm. Clinical Response Criteria: -CR: All target and nontarget lesion(s) no longer visible, maintained for at least 4 weeks and no new lesions.

Analysis population: The FAS included all enrolled participants. Only Groups 1, 2, 3, 4, and 6 were planned for this outcome measure.

Groups in this outcome
