Outcome Measures

Primary Outcome Measures :

1. Progression-free Survival (PFS) Based on Blinded Independent Central Review (BICR) in the Hormone Receptor-Positive Cohort in Participants With HER2-low Breast Cancer [ Time Frame: From the date of randomization to the earliest date of the first objective documentation of radiographic disease progression or death due to any cause, up to approximately 3 years ]
   Progression-free survival (PFS), defined as at least a 20% increase in the sum of diameters of target lesions, was assessed from the date of randomization to the date of the first radiographic disease progression or death due to any cause, whichever came first. PFS was based on blinded independent central review (BICR) in the hormone receptor-positive cohort according to modified Response Evaluation Criteria in Solid Tumors (mRECIST) version 1.1. Median PFS was from Kaplan-Meier analysis. Confidence interval for median was computed using the Brookmeyer-Crowley method.

Secondary Outcome Measures :

3. Progression-free Survival Based on Investigator Assessment in Participants With HER2-low Breast Cancer (All Patients) [ Time Frame: From the date of randomization to the earliest date of the first objective documentation of radiographic disease progression or death due to any cause, up to approximately 3 years ]
   Progression-free survival (PFS), defined as at least a 20% increase in the sum of diameters of target lesions, was assessed from the date of randomization to the date of the first radiographic disease progression or death due to any cause, whichever came first.

4. Overall Survival (OS) in the Hormone Receptor-Positive Cohort in Participants With HER2-low Breast Cancer [ Time Frame: From the date of randomization up to the date of death due to any cause, up to approximately 3 years ]
   Overall survival (OS) was defined as the time from the date of randomization to the date of death due to any cause. If there was no death reported for a participant before the data cutoff for OS analysis, OS was censored at the last contact date at which the participant was known to be alive.
5. Number of Overall Survival Events (Deaths) [ Time Frame: From the date of randomization up to the date of death due to any cause, up to approximately 3 years ]
6. Overall Survival (OS) in All Patients [ Time Frame: From the date of randomization up to the date of death due to any cause, up to approximately 3 years ]
   Overall survival (OS) was defined as the time from the date of randomization to the date of death due to any cause. If there was no death reported for a participant before the data cutoff for OS analysis, OS was censored at the last contact date at which the participant was known to be alive.
7. Best Overall Response and Confirmed Objective Response Rate (ORR) in the Hormone Receptor-Positive Cohort in Participants With HER2-low Breast Cancer [ Time Frame: From screening and every 6 weeks up to withdrawal of subject consent, progressive disease (PD), or unacceptable toxicity, up to approximately 3 years ]
   Best overall response rate and confirmed objective response rate (ORR) were assessed by blinded independent central review (BICR) and investigator assessment.
