paclitaxel trastuzumab ...Study Participants
121The 3 weekly combination of trastuzumab and paclitaxel has been approved for the treatment of advanced breast cancer based on a large pivotal study. However, mono and combination chemotherapy trials suggest that weekly paclitaxel has a better therapeutic index, especially in the palliative setting. The present trial examines the efficacy and safety of weekly paclitaxel over a limited duration combined with continued trastuzumab in HER2+ patients.
Weekly paclitaxel (90 mg/m² iv, 12 courses) plus weekly trastuzumab (4mg/kg body weight iv as loading dose, 2 mg/kg iv from week 2 onwards; continued until disease progression)
