Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Progression-free Survival (PFS)	PFS is defined as from the date of randomization until the date of disease progression (PD) or death, whichever occurs earlier. Disease progression will be determined according to Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v 1.1) by Independent Reviewing Committee (IRC).	Up to 3 years
Secondary	Overall Survival (OS)	OS is defined as from the date of randomization to death from any cause.	Up to 4 years
Secondary	Objective Response Rate (ORR) by IRC	ORR is defined as the proportion of participants who achieve a complete response (CR) or partial response (PR).	Up to 4 years
Secondary	Duration of Response (DOR) by IRC	DOR is defined as from the date of first onset of tumor response (CR or PR) to PD or death, whichever occurs earlier.	Up to 4 years
Secondary	Clinical Benefit Rate (CBR) by IRC	CBR is defined as best overall response of CR or PR or durable stable disease (SD) (duration of SD = 6 months after randomization).	Up to 4 years
Secondary	Percentage of Participants Experiencing Adverse Events (AEs) According to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0		First dose date up to 4 years plus 30 days
Secondary	Percentage of Participants Experiencing Serious Adverse Events (SAEs) According to NCI CTCAE Version 5.0		First dose date up to 4 years plus 30 days
Secondary	Change From Baseline of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, Core 30, Version 3.0 (EORTC QLQ-C30) Score	The EORTC QLQ-C30 is a questionnaire to assess quality of life of cancer patients, it is composed of 30 questions (items) to assess 15 scales; 1 global health status/quality of life (QOL), 5 functional scales (physical, role, cognitive, emotional, and social), and 9 symptom/item scales(fatigue, nausea and vomiting, pain, dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties). All of the scales and single-item measures range in score from 0 to 100. A high scale score represents a higher response level. Thus, a high score for a functional scale represents a high/healthy level of function, a high score for the global health status/QOL represents a high QOL, but a high score for a symptom scale/item represents a high level of symptomatology/problems.	Baseline, up to 4 years
Secondary	Change From Baseline of the European Quality of Life 5-Dimensions 5 Levels Instrument (EuroQOL EQ-5D-5L) Score	The EQ-5D-5L is an instrument for use as a measure of health outcome.The EQ-5D-5L consists of 2 sections: the EuroQoL (5 dimensions) (EQ-5D) descriptive system and the EuroQoL visual analogue scale (EQ-VAS). The descriptive system comprises the following 5 dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems, and extreme problems. Rating gets recorded on a vertical VAS in which the endpoints are labeled best imaginable health state is 100 (on the top) and worst imaginable health state is 0 (on the bottom). Higher scores of EQ-VAS indicate better health.	Baseline, up to 4 years
Secondary	Percentage of Participants Experiencing Treatment-Emergent Adverse Events Assessed by Patient-Reported Outcomes Version of the Common Terminology Criteria for Adverse Events (NCI PRO-CTCAE)	NCI PRO-CTCAE is a patient-reported item library used to evaluate symptomatic treatment-emergent adverse events in participants on cancer clinical trials. The items selected for this study include: decreased appetite, nausea, vomiting, constipation, diarrhea, abdominal pain, shortness of breath, hair loss, and fatigue.	Baseline, up to 4 years
Secondary	Pharmacokinetic (PK) Parameter: Cmax of Sacituzumab Govitecan-hziy and Free SN-38	Cmax is defined as the maximum observed concentration of drug.	Up to 4 years
Secondary	PK Parameter: Tmax of of Sacituzumab Govitecan-hziy and Free SN-38	Tmax is defined as the time to maximum drug concentration.	Up to 4 years
Secondary	PK Parameter: Ctrough of Sacituzumab Govitecan-hziy and Free SN-38	Ctrough is defined as the concentration of drug at the end of the dosing interval.	Up to 4 years
