Conditions: Metastatic Breast Cancer
Keywords: Herceptin metastatic breast cancer CT-P6 Her 2-positive
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 475
Healthy volunteers: no

Brief summary:
The purpose of the study is to demonstrate equivalence

Detailed description:
Patients will receive CT-P6 or Herceptin every 3 weeks.

Arms:
arm 1: CT-P6 was administered at a loading dose of 8 mg/kg body weight by intravenous (IV) infusion over 90 minutes on Day 1, Cycle 1, then at 6 mg/kg repeated at 3-weekly intervals until disease progression, death or discontinuation.

Paclitaxel was administered at a dose of 175 mg/m2 body surface area (BSA) as a continuous 3-hour IV infusion on the day following the first dose of study drug (CT-P6). If the first dose of study drug was well tolerated, subsequent doses of paclitaxel were given immediately after the next dose of study drug. Paclitaxel cycles were repeated every 3 weeks until disease progression, death or discontinuation. arm 2: Herceptin was administered at a loading dose of 8 mg/kg body weight by IV infusion over 90 minutes on Day 1, Cycle 1, then at 6 mg/kg repeated at 3-weekly intervals until disease progression, death or discontinuation.

Paclitaxel was administered at a dose of 175 mg/m2 BSA as a continuous 3-hour IV infusion on the day following the first dose of study drug (Herceptin). If the first dose of study drug was well tolerated, subsequent doses of paclitaxel were given immediately after the next dose of study drug. Paclitaxel cycles were repeated every 3 weeks until disease progression, death or discontinuation.
