Primary Outcome Measures

Measure:Progression-free survival (PFS)
Time Frame:Up to approximately 3 years
Safety Issue:
Description:PFS is defined as the time from the date of randomization to the date of the first documentation of disease progression or death (whichever occurs first) according to blinded independent central review (BICR) using Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1).

Secondary Outcome Measures

Measure:Objective Response Rate (ORR)
Time Frame:Up to approximately 3 years
Safety Issue:
Description:ORR is defined as the proportion of participants who have a best overall response of either Complete Remission (CR) or Partial Response (PR) that is confirmed ≥ 4 weeks later according to BICR using RECIST 1.1.
Measure:Overall Survival (OS)
Time Frame:Up to approximately 5 years
Safety Issue:
Description:OS is defined as the time from the date of randomization to the date of death from any cause.
Measure:Duration of Response (DOR)
Time Frame:Up to approximately 3 years
Safety Issue:
Description:DOR is defined as the time from the date a response was first documented until the date of the first documentation of disease progression or date of death (whichever occurs first).
Measure:Clinical Benefit Rate (CBR)
Time Frame:Up to approximately 3 years
Safety Issue:
Description:CBR is defined as best overall response of CR or PR or durable stable disease (duration of SD ≥ 6 months after randomization).
Measure:European Organisation for Research and Treatment of Cancer Quality of Life (EORTC QLQ-C30) Questionnaire Score
Time Frame:Up to approximately 3 years
Safety Issue:
Description:The EORTC QLQ-C30 is a questionnaire to assess quality of life of cancer patients, it is composed of 30 questions (items) resulting in 5 functional scales, 1 global health status scale, 3 symptom scales, and 6 single items. Scoring of the QLQ-C30 is performed according to QLQ-C30 Scoring manual. All of the scales and single-item measures range in score from 0 to 100. Higher score for the functioning scales and global health status denote a better level of functioning (i.e. a better state of the participant), while higher scores on the symptom and single-item scales indicate a higher level of symptoms (i.e. a worse state of the participant).
Measure:European Quality of Life 5-Dimensions 5-Levels (EQ-5D-5L) Questionnaire Score
Time Frame:Up to approximately 3 years
Safety Issue:
Description:The EQ-5D-5L is a standard measure of health-related quality of life. The tool consists of the EQ-5D-5L descriptive part and the EQ visual analogue scale (VAS). The descriptive part comprises 5 dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression). Each of these 5 dimensions has 5 levels (no problem, slight problems, moderate problems, severe problems, and extreme problems). Results for each of the 5 dimensions are combined into a 5-digit number to describe the participant's health state. The EQ-VAS records the participant's health on a 0-100 mm VAS scale, with 0 indicating "the worst health you can imagine" and 100 indicating "the best health you can imagine." Higher scores of EQ VAS indicate better health.
Measure:Patient Reported Outcomes Version of the Common Terminology Criteria for Adverse Events Questionnaire Score (PRO-CTCAE™)
Time Frame:Up to approximately 3 years
Safety Issue:
Description:Nine selected symptoms (decreased appetite, nausea, vomiting, constipation, diarrhea, abdominal pain, shortness of breath, hair loss, and fatigue) from the PRO-CTCAE™ will be assessed. Responses are scored from 0 to 4 with no standardized scoring rules.
Measure:Percentage of Participants Experiencing Treatment Emergent Adverse Events (TEAEs)
Time Frame:Up to approximately 3 years
Safety Issue:
Description:
Measure:Percentage of Participants Experiencing Treatment Emergent Serious Adverse Events (TESAEs)
Time Frame:Up to approximately 3 years
Safety Issue:
Description:
Measure:Percentage of Participants Experiencing any Clinically Significant Laboratory Abnormalities
Time Frame:Up to approximately 3 years
Safety Issue:
Description:
Measure:Change From Baseline in Eastern Cooperative Oncology Group (ECOG) Performance Status
Time Frame:Baseline, Up to approximately 3 years
Safety Issue:
Description:
Measure:Immunogenicity Assessment
Time Frame:Up to approximately 3 years
Safety Issue:
Description:Number of participants who test positive for anti-drug antibodies to sacituzumab govitecan-hziy will be reported.
