|---|---|---|
| Objective Response Rate (ORR) as Centrally Measured by Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) Criteria | Up to disease progression or end of study (up to 1 year and 9 months) | ORR was defined as the percentage of participants with a best overall response (BOR) of partial or complete response (PR or CR). BOR was defined as the best confirmed response observed from first administration of study drug until disease progression. CR was defined as disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. PR was defined as ≥30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Disease Control Rate (DCR) as Centrally Measured by Independent Review Committee (IRC) | Up to disease progression or end of study (up to 2 years and 9 months) | DCR was defined as the percentage of participants with a BOR of confirmed CR, confirmed PR or stable disease (SD) ≥6 weeks. BOR was defined as the best confirmed response observed from first administration of study drug until disease progression. CR was defined as disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. PR was defined as ≥30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. SD was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD), taking as reference the smallest sum diameters while on study. PD was defined as ≥ 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. |
| Progression-Free Survival (PFS) as Centrally Measured by Independent Review Committee (IRC) | From the start of the study up to disease progression or death (up to 2 years and 9 months) | PFS was defined as the time from the start date of treatment to date of the first documented progression or death due to any cause. |
| Overall Survival (OS) | Until death or loss to follow-up or end of study (up to 2 years and 9 months) | OS was defined as the time from the start date of treatment to date of death due to any cause. Participants with no documented death were censored at the last date known to be alive. |
| Duration of Response (DOR) as Centrally Measured by Independent Review Committee (IRC) | Up to disease progression or end of study (up to 2 years and 9 months) | DOR was defined as the time from the date of the initial PR or CR to date of the first documented progression or death due to any cause. CR was defined as disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm.

| Number of Participants With Treatment-Emergent Adverse Events (TEAEs) Assessed by National Cancer Institute Common Terminology Criteria (NCI CTCAE) v5.0 and Serious Adverse Events (SAEs) | From first dose of study drug up to 30 days post last dose (Up to 2 years and 9 months) | An AE is any untoward medical occurrence in a participant or clinical trial participant administered a medicinal product and which does not necessarily have a causal relationship with this treatment. A TEAE is defined as an AE that either starts or worsens in severity on or after the first administration of the study drug and within 30 days of the last administration of the study drug.
