About
This is a randomized, open-label, two-arm, phase III trial in Germany to investigate whether vinorelbine-based triple combination presents a less toxic treatment option than docetaxel-based triple combination in patients with HER2-positive advanced breast cancer who have not previously received any systemic treatment in the metastatic setting.
The primary objective of the study is to compare patient-reported quality of life in the two treatment arms. Patients will be followed-up for survival until death or end of study after at least 79 deaths occured in each arm, whatever comes first.
