- From randomization until disease progression (assessed every 6 weeks for 9 months and then every 9 weeks thereafter until the occurrence of progression of disease; maximum exposure: 29.6 months)
What was measured
Time to Progression (TTP) was defined as the time from the date of randomization to the date of the first evidence of disease progression as assessed using RECIST 1.1 criteria. The date of progression was date of the last observation or radiological assessment of target lesions that either showed a predefined increase (≥20%) in the sum of the target lesions or the appearance of new non-target lesions. Participants without progression were censored.
Analysis population: Participants in the BM-ve 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 either by gravity or with an infusion pump on Days 1 and 8 of a 21-day treatment cycle for up to 29.6 months. Infusion rate for the first 15 minutes started with 50 mg/hour or less with a subsequent infusion of 100 to 200 mg/hour up to a maximum recommended rate (advanced every 15 to 30 minutes) of 500 mg/hour with a subsequent infusion of 1000 mg/hour. Participants continued treatment until progression of disease requiring treatment discontinuation or occurrence of unacceptable AEs.
Treatment of Physician's Choice (TPC)
Participants received TPC (ie, eribulin, capecitabine, gemcitabine, or vinorelbine), administered as a single-agent regimen that was selected by the investigator before participant randomization. Participants continued treatment until progression of disease requiring treatment discontinuation or occurrence of unacceptable AEs. Eribulin was administered IV over 2 to 5 minutes at a dose 1.4 mg/m\^2 at North American sites and 1.23 mg/m\^2 at European sites on Days 1 and 8 of a 21-day cycle for up to 15.3 months. Lower doses were administered on the same schedule to participants with moderate hepatic impairment (ie, Child-Pugh B; 0.7 mg/m\^2 and 0.67 mg/m\^2 for North American and European sites, respectively). 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 for up to 10.6 months. Gemcitabine 800 to 1200 mg/m\^2 was administered IV over 30 minutes on Days 1, 8, and 15 of a 28-day cycle for up to 8.1 months. Vinorelbine 25 mg/m\^2 was administered as a weekly IV injection over 6-10 minutes for up to 11.5 months. Vinorelbine was not allowed as TPC for any participant with Grade 2 neuropathy.
