E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
to evaluate, as a first-line chemotherapy, the disease control rate (DCR) of weekly oral vinorelbine as a single-agent versus weekly paclitaxel as a single-agent in estrogen receptor positive, HER2 negative patients with advanced breast cancer. |
|
E.2.2 | Secondary objectives of the trial |
- to evaluate the response rate, duration of response, duration of stable disease, progression free survival, time-to-treatment failure and overall survival of both regimens
- to evaluate the safety profile in both study arms
- to assess the quality of life of patients |

E.2.3 | Trial contains a sub-study | No |

|
E.5.2 | Secondary end point(s) |
- to evaluate the response rate, duration of response, duration of stable disease, progression free survival, time-to-treatment failure and overall survival of both regimens

|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Efficacy will be determined at baseline, then every 6 weeks until documented disease progression, unacceptable toxicity or patient’s refusal.
