Outcome Measures

Primary Outcome Measures :
  1. Progressive-free Survival (PFS) Per Investigator Assessment [ Time Frame: Every 6 weeks until disease progression or death which ever occurred first up to about 41 months ]
    PFS was defined as the time from the date of randomization to the date of first radiologically documented tumor progression or death from any cause, whichever occurs first. PFS primary analysis performed when 415 events were reached. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.


Secondary Outcome Measures :
  1. Overall Survival (OS) [ Time Frame: Every 3 months until death up to 41 months ]
    OS was defined as the time from date of randomization to the date of death from any cause. Final OS was conducted when 388 deaths occurred.

  2. Overall Response Rate (ORR) [ Time Frame: Every 6 weeks until disease progression or death which ever occurred first up to about 41 months ]
    ORR was defined as the percentage of participants whose best overall response was either complete response (CR) or partial response (PR) according to RECIST version 1.0. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.

  3. Clinical Benefit Rate (CBR) [ Time Frame: Every 6 weeks until disease progression or death which ever occurred first up to about 41 months ]
    CBR was defined as the percentage of participants whose best overall response, according to RECIST, was either complete response (CR), a partial response (PR) or stable disease (SD) lasting for at least 24 weeks. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; SD = Neither sufficient shrinkage to qualify for PR or CR nor an increase in lesions which would qualify for PD; PD = At least a 20% increase in the sum of the longest diameter of all measured target lesions, taking as reference the smallest sum of longest diameter of all target lesions recorded at or after baseline.

  4. Median Time to Deterioration of the ECOG Performance Status Score [ Time Frame: baseline, until disease progression or death up to about 41 months ]
    Time to deterioration of ECOG performance status score was summarized at time of assessment. ECOG (Eastern Cooperative Oncology Group)performance scale is a standard criteria for measuring how treatment of cancer impacts their level of functioning in terms of their ability to care for themselves, daily activity, & physical ability (walking, working, etc.). Scale score ranges from 0 to 5, 5 being the worst. ECOG scale index: 0 - Fully active, able to carry on all pre-disease performance without restriction. 1 - Restricted in physically strenuous activity but ambulatory & able to carry out work of a light or sedentary nature, e.g., light housework, office work. 2 - Ambulatory & capable of all self-care but unable to carry out any work activities. Up & about more than 50% of waking hours. 3 - Capable of only limited self-care, confined to bed or chair more than 50% of waking hours. 4 - Completely disabled. Cannot carry on any self-care. Totally confined to bed or chair. 5 - Dead

  5. PRO: Time to Deterioration in Global Health Status/QoL Domain Score of the European Organization for the Research and Treatment of Cancer (EORTC)-Core Quality of Life Questionnaire (QLQ-C30) (by at Least 10%) [ Time Frame: Baseline, until disease progression or death up to about 41 months ]
    PRO = patient reported outcomes; Time to deterioration (≥ 10% worsening from baseline), in the global health status of EORTC QLQ-C30 scale was done in the 3 functional scales (emotional, physical, & social functioning [EF, PF, & SF]). It contains 30 items & is composed of multi-item scales & single-item measures. These include 5 functional scales (physical, role, emotional, social & cognitive functioning), 3 symptom scales (fatigue, pain, nausea, & vomiting), a global health status/QoL scale, and 6 single items (dyspnea, diarrhea, constipation, anorexia, insomnia & financial impact). Each of the multi-item scale includes a different set of items - no item occurs in more than 1 scale. Each item in the EORTC QLQ-C30 has 4 response categories (1=Not at all, 2= A little, 3= Quite a bit, 4= Very much) with the higher number representing a worse outcome. The global health domain score of the QLQ-C30 questionnaire was pre-specified as the primary QoL domain of interest & disclosed here.

  6. Everolimus Blood Concentrations by Leading Dose and Time Point [ Time Frame: Cycle 2, Day 1 ]
    Pre-dose (Cmin) and 2 hours post-dose (C2h) everolimus PK blood samples were collected at Cycle 2 Day 1. Only valid everolimus PK blood samples collected at steady state were used in the analyses.

  7. Vinorelbine Blood Concentrations by Leading Dose and Time Point [ Time Frame: Cycle 2, Day 1 ]
    Pre-infusion (Cmin) and end of infusion (C2h) vinorelbine PK blood samples were collected at Cycle 2 Day 1. Only valid vinorelbine PK blood samples collected at steady state were used in the analyses.

  8. Trastuzumab Blood Concentrations by Leading Dose and Time Point [ Time Frame: Cycle 3, Day 1 ]
    Pre-infusion (Cmin) and end of infusion (C2h) trastuzumab PK blood samples were collected at Cycle 3 Day 1. Only valid trastuzumab PK blood samples collected at steady state were used in the analyses.
