What was measured

Percentage of participants who achieved an objective response of Complete Response (CR) or Partial Response (PR) per Response Evaluation Criteria in Solid Tumor (RECIST) v1.1. CR is defined as disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) had to have reduction in short axis to \<10 mm. PR is defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Progressive Disease (PD) is defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study including baseline, or the appearance of one or more new lesions.

Analysis population: Part 2 mITT participants that were evaluable for this outcome measure.
