Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To make a preliminary assessment of the efficacy of pertuzumab in combination with Herceptin® in patients who have progressed on Herceptin®-based therapy as determined by the objective response rate and/or the clinical benefit response rate (total of the number of responses and the number > 6 month stable diseases).; Secondary Objective: •To assess the safety profile of the combination of pertuzuamb and Herceptin®. •To determine the duration of response, time to response, time to progression, progression-free survival and overall survival. •To evaluate biomarkers that may be associated with clinical benefit due to pertuzumab in combination with Herceptin®. ; Primary end point(s): Objective Response (OR): Objective response by tumor measurement according to RECIST criteria has occurred if there is documented and confirmed Complete Response (CR) or Partial Response (PR). Clinical Benefit Response (CBR): includes patients who have met the criteria for objective response at any time and for any duration (minimum of 4 weeks) and patients whose best response was stable disease (defined according to RECIST criteria) that lasted at least 6 months (or 8 cycles of therapy). Both OR and CBR are based on evaluations of target and non-target lesions to ascertain the overall best response status of each patient. | — |
