What was measured

Treatment-emergent adverse events (TEAEs) were defined as any adverse events (AEs) that begin or worsen on or after the start of study drug through 30 days after the last dose of study drug. The severity was graded based on the National Cancer Institute's Common Terminology Criteria for Adverse Events Version 5.0. An AE that met one or more of the following outcomes was classified as serious: * Fatal * Life-threatening * Disabling/incapacitating * Results in hospitalization or prolongs a hospital stay * A congenital abnormality * Other important medical events may also be considered serious AEs if they may require medical or surgical intervention to prevent one of the outcomes listed above

Analysis population: Participants in the Safety Population were analyzed.

Groups in this outcome

Sacituzumab Govitecan

Participants received sacituzumab govitecan 10 mg/kg of body weight, administered as a slow IV infusion on Days 1 and 8 of a 21-day treatment cycle until progression of disease, occurrence of unacceptable AEs, or another treatment discontinuation criterion was met (up to 40.1 months).

Treatment of Physician's Choice (TPC)

Participants received TPC (ie, eribulin, capecitabine, gemcitabine, or vinorelbine), administered as a single-agent treatment that was determined by the investigator before participant randomization until progression of disease, occurrence of unacceptable AEs, or another treatment discontinuation criterion was met. Dosing per NCCN guidelines (with dose modifications for if toxic) * Eribulin was administered IV at a dose 1.4 mg/m\^2 at North American sites and 1.2 mg/m\^2 at European sites on Days 1 and 8 of a 21-day cycle (up to 22.5 months). * Capecitabine 1000 to 1250 mg/m\^2 was administered in a 21-day cycle, with capecitabine administered orally twice daily for 2 weeks followed by 1-week rest period (up to 12.9 months). * Gemcitabine 800 to 1200 mg/m\^2 was administered IV on Days 1, 8, and 15 of a 28-day cycle (up to 22.3 months). * Vinorelbine 25 mg/m\^2 was administered as a weekly IV injection (up to 8.1 months). Vinorelbine was not allowed as TPC for any participant with Grade 2 neuropathy.
