Primary Outcome Measures
NameTimeMethod
Progression-free Survival (PFS) Per Investigators' Assessment Based on Local Radiology Review - Full Populationdate of randomization to the date of first documented tumor progression or death from any cause, whichever occurs first, reported between day of first patient randomized up to about 56 months

PFS is defined as the time from the date of randomization to the date of first documented tumor progression or death from any cause, whichever occurs first. This was assessed in the full patient population.

Progression-free Survival (PFS) Per Investigators' Assessment Based on Local Radiology Review - (Hormone Receptor (HR)-Negative Populationdate of randomization to the date of first documented tumor progression or death from any cause, whichever occurs first, reported between day of first patient randomized up to about 56 months

PFS is defined as the time from the date of randomization to the date of first documented tumor progression or death from any cause, whichever occurs first. This was assessed in the HR-negative patient population.

Secondary Outcome Measures
NameTimeMethod
Overall Survival (OS) - Full Populationup to about 76 months

OS is defined as the time from date of randomization to the date of death due to any cause. For patients with documented progression, survival follow up was performed either by telephone or clinic visit at least every 3 months. Additional survival updates were requested prior to interim or final analysis or prior to providing data to the health authorities. This was assessed in the full patient population.

Overall Response Rate (ORR) - Full Populationup to about 23 months

ORR is defined as the percentage of participants whose best overall response is either complete response (CR) or partial response (PR) according to RECIST. This was assessed in the full patient population. Complete response is achieved when all lesions evaluated at Baseline are absent at subsequent visit.

Time to Deterioration of Eastern Cooperative Oncology Group Performance Status (ECOG-PS) Score - Full Populationup to about 56 months

Time to definitive deterioration of the ECOG PS by one category of the score from baseline will be performed. Baseline is the last available assessment on or before randomization date. A deterioration is considered definitive if no improvements in the ECOG PS status is observed at a subsequent time of measurement during the treatment period following the time point where the deterioration is observed.

Overall Response Rate (ORR) - HR-negative Populationup to about 23 months

ORR is defined as the percentage of participants whose best overall response is either complete response (CR) or partial response (PR) according to RECIST. This was assessed in a subset of patients with Hormone Receptor Negative disease. Complete response is achieved when all lesions evaluated at Baseline are absent at subsequent visit.

Clinical Benefit Rate (CBR) Equal to or Greater Than 24 Weeks - Full Populationup to about 23 months

CBR is defined as the percentage of participants whose best overall response is either complete response (CR), a partial response (PR) or stable disease (SD) lasting for at least 24 weeks, according to RECIST. This was assessed in the full patient population. Complete response is achieved when all lesions evaluated at Baseline are absent at subsequent visit.

Clinical Benefit Rate (CBR) Equal to or Greater Than 24 Weeks - HR-negative Populationup to about 23 months

CBR is defined as the percentage of participants whose best overall response is either complete response (CR), a partial response (PR) or stable disease (SD) lasting for at least 24 weeks, according to RECIST. This was assessed in a subset of patients with Hormone Receptor Negative disease. Complete response is achieved when all lesions evaluated at Baseline are absent at subsequent visit.

Time to Overall Response Based on Investigator - Full Populationup to about 23 months

Time to overall response defined as the time between date of randomization until first documented response Complete reseponse (CR) or partial response (PR) ), according to RECIST. This was assessed in the full patient population and in a subset of patients with Hormone Receptor Negative disease. Complete response is achieved when all lesions evaluated at Baseline are absent at subsequent visit.

Overall Response (OR) - Full Populationup to about 23 months

OR applies only to patients whose best OR was CR or PR. Start date = date of first documented response (CR or PR) and end date = date of documented response (CR or PR) and end date = date of event defined as the first documented progression or death due to underlying cause. Complete response is achieved when all lesions evaluated at Baseline are absent at subsequent visit.

Overall Survival (OS) - HR-negative Populationup to about 76 months

OS is defined as the time from date of randomization to the date of death due to any cause. For patients with documented progression, survival follow up was performed either by telephone or clinic visit at least every 3 months. Additional survival updates were requested prior to interim or final analysis or prior to providing data to the health authorities. This was assessed in the HR-negative patient population.

Time to Overall Response Based on Investigator - HR-negative Populationup to about 23 months

Time to overall response defined as the time between date of randomization until first documented response Complete reseponse (CR) or partial response (PR) ), according to RECIST. This was assessed in the full patient population and in a subset of patients with Hormone Receptor Negative disease. Complete response is achieved when all lesions evaluated at Baseline are absent at subsequent visit.

Overall Response (OR) - HR-negative Populationup to about 23 months

OR applies only to patients whose best OR was CR or PR. Start date = date of first documented response (CR or PR) and end date = date of documented response (CR or PR) and end date = date of event defined as the first documented progression or death due to underlying cause. This was assessed in the HR-negative patient population. Complete response is achieved when all lesions evaluated at Baseline are absent at subsequent visit.

Everolimus Blood Level Concentrations at Steady States for Everolimuspredose, 2 hours post-dose at Cycle 2/Day 1, Cycle 2/Day 15, Cycle 2/ Day 22

Blood levels at steady states for everolimus 10 mg/day and 5 mg/day. Only valid samples are included. Some patients had dose reduction to 5 mg daily dose therefore the everolimus blood concentration for them have been summarized separately. Cycle = 28 days

Trastuzumab Serum ConcentrationsCycle 4/Day 1 (Pre-infusion and end of infusion)

Blood levels at steady states for everolimus/placebo

Time to Deterioration of Eastern Cooperative Oncology Group Performance Status (ECOG-PS) Score - HR-negative Populationup to about 56 months

Time to definitive deterioration of the ECOG PS by one category of the score from baseline will be performed. Baseline is the last available assessment on or before randomization date. A deterioration is considered definitive if no improvements in the ECOG PS status is observed at a subsequent time of measurement during the treatment period following the time point where the deterioration is observed.
