What was measured

ORR was defined as percentage of participants having CR or PR as determined by investigator assessment of radiographic disease per RECIST v1.1. CR per RECIST v 1.1 was defined as disappearance of all target lesions. PR: At least a 30% decrease in the sum of diameters (SOD) of target lesions, taking as reference the Baseline sum diameters. Per Cheson criteria, CR: complete disappearance of all detectable clinical evidence of disease and disease-related symptoms. PR: at least a 50% decrease in SPD of up to 6 of the largest dominant nodes or nodal masses. Per RANO criteria, CR: Complete disappearance of all enhancing measurable and non-measurable disease sustained. PR: at least ≥50% decrease compared with baseline in the SOD of all measurable enhancing lesions sustained.

Analysis population: The Phase 1, Part 1 Full Analysis Population includes all participants enrolled in the study who received at least 1 dose of study drug.
