What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Part 1 and 2 : Number of Participants With Treatment Emergent Adverse Events
Time Frame: Baseline through 42-49 days after end of treatment, estimated up to 27 months (24 months with 100 day FU period).
|
A treatment-emergent AE was defined as an event occurring after exposure to at least 1 dose of study drug.
A treatment-related AE was defined as an event with a definite, probable, or possible causality to study medication.
A serious AE is an event resulting in death, hospitalization, persistent or significant disability/incapacity, or is life threatening, a congenital anomaly/birth defect or requires medical or surgical intervention to prevent 1 of the outcomes above.
The intensity of an AE was graded according to the National Cancer Institute common terminology criteria for adverse events (NCI-CTCAE) version 4.03: Grade 1 (Mild); Grade 2 (Moderate); Grade 3 (Severe); Grade 4 (life-threatening).
|
Baseline through 42-49 days after end of treatment, estimated up to 27 months (24 months with 100 day FU period).
|
Part 1 and 2: Objective Response Rate Based on Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1)
Time Frame: Every 9 weeks for the duration of study participation; estimated minimum of 6 months.
|
ORR was defined as the percentage of participants having a complete response (CR) or partial response (PR) as determined by investigator assessment of radiographic disease per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.
CR is disappearance of all target lesions.
Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm.
PR is at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of diameters.
A participant was considered as an objective responder if the participant had a best overall response of CR or PR.
|
Every 9 weeks for the duration of study participation; estimated minimum of 6 months.
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|

|
Baseline to Week 5/6 or week 8/9
|
Parts 1 and 2: Progression-free Survival Based on RECIST v1.1.
Time Frame: Every 9 weeks from date of randomization until the date of first documented progression or date of death from any cause whichever came first, assessed up to 24 months
|
Defined as the time from date of first dose of study drug until the earliest date of disease progression per RECIST v1.1, or death due to any cause, if occurring sooner than progression.
|
Every 9 weeks from date of randomization until the date of first documented progression or date of death from any cause whichever came first, assessed up to 24 months
|
Parts 1 and 2: Duration of Response Based on RECIST v1.1
Time Frame: Every 9 weeks from date of randomization until the date of first documented progression or date of death from any cause whichever came first, assessed up to 24 months
|
Defined as the time from earliest date of disease response until the earliest date of disease progression per RECIST v1.1, or death due to any cause, if occurring sooner than progression.
|
Every 9 weeks from date of randomization until the date of first documented progression or date of death from any cause whichever came first, assessed up to 24 months
