An adverse event (AE) was any untoward medical occurrence in a participant who received study intervention without regard to possibility of causal relationship. TEAEs are defined as newly occurring AEs or those worsening after first dose. As per Common Terminology Criteria for Adverse Events (CTCAE) version 4, Grade 1= mild AE; Grade 2= moderate AE; Grade 3= severe AE; Grade 4= life-threatening or disabling AE; Grade 5= death related to an AE. Serious TEAE (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. SAEs were determined according to the investigator's assessment. Results as of 16 Aug 2022 are reported.

PTs for the cluster terms are: ANEMIA, including Anemia, Hematocrit decreased, Hemoglobin decreased, and Red blood cell count decreased; THROMBOCYTOPENIA, including, Thrombocytopenia and Platelet count decreased; NEUTROPENIA, including Febrile neutropenia, Neutropenia and Neutrophil count decreased; LEUKOPENIA, including Leukopenia, White blood cell count decreased. Events in any grade with at least 1 occurrence in participants are reported for this outcome measure. Results as of 16 Aug 2022 are reported.

rPFS is defined as the time from the date of randomization to first objective evidence of radiographic progression as assessed in soft tissue per RECIST 1.1, or death, whichever occurs first. Soft tissue disease status was assessed at regular intervals during the course of the study by computed tomography (CT) of chest and CT or magnetic resonance imaging (MRI) of abdomen and pelvis. Progression is defined using RECIST 1.1 as a \>=20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions. Results as of 16 Aug 2022 are reported for this outcome measure.
