Efficacy and Safety of Everolimus in Combination Therapy, in Patients With HER2-overexpressing Metastatic Breast Cancer

Everolimus (RAD001) was supplied as tablets in 3 different dosage strengths, 2.5, 5, and 10 mg. The drug was packaged in blisters containing 10 tablets per blister. Blisters and packaging labels were compliant with local regulations and were printed in local language.

Commercially-available trastuzumab was used in this study. A 4 mg/kg loading dose was administered, intra-venous (IV), over 90 minutes on Day 1 (if patient was not already receiving trastuzumab); this was followed by weekly trastuzumab 2 mg/kg IV administered over 30 minutes. For patients who continued to receive trastuzumab and everolimus after completion/discontinuation of chemotherapy in the core treatment phase, trastuzumab may have been administered once every 3 weeks at a dose of 6 mg/kg. PT = Paclitaxel \& Trastuzumab

Commercially-available paclitaxel was used in this study. Paclitaxel infusion was administered on Days 1, 8, and 15 of each 28-day cycle, after administration of trastuzumab. Paclitaxel (80 mg/m2) was administered as a 60-minute continuous IV infusion after standard premedication. Patients received paclitaxel for 6 cycles. At the investigator's discretion, treatment with paclitaxel could continue beyond 6 cycles.
