What was measured

ORR was the percentage of participants who had CR or PR defined using RECIST v1.1 criteria. CR was defined as the disappearance of all target and non-target lesions and any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm and normalization of tumor marker level of non-target lesions. PR was defined as having a ≥30% decrease in sum of LD of target lesions. Percentage of participants calculated as: (number of participants with CR + PR)/(total number of participants)\*100.

Analysis population: All participants according to the treatment group to which they were randomized.
