METEORA-II: MEtronomic TrEatment Option in Advanced bReast cAncer
Study Details
Study Description
Brief Summary
This is a multi-center, randomized phase II trial that will randomise women with ER-positive, HER2-negative (Human Epidermal Growth factor Receptor 2-negative) metastatic or locally relapsed breast cancer in a ratio of 1:1 to receive a metronomic regimen of vinorelbine plus cyclophosphamide and capecitabine, or the conventional paclitaxel monotherapy.

Phase 2 |
Detailed Description
The prognosis for patients with locally advanced or metastatic disease (ABC) remains poor, with a median survival of 2-4 years. About 10% of newly diagnosed BC patients present with ABC, and 30% to 50% of patients diagnosed at earlier stages will subsequently develop metastatic disease.
In the first-line treatment of HER2 (Human Epidermal Growth factor Receptor 2) negative ABC patients, various chemotherapy regimens can be used including taxanes, which are among the most active agents in BC. Single agent response rates range from 20 to 50%. However, eventually all patients will progress with a median time to progression of 5 to 7 months. A weekly (qw) over a three-weekly (q3w) administration schedule of paclitaxel has been shown to be more effective in the metastatic as well as in the adjuvant setting after standard chemotherapy
The VEX regimen was recently investigated within a phase II trial currently ongoing at the European Institute of Oncology (IEO) (IEO number IEOS582/111; EudraCT Number: 2010-024266-21; title: "A phase II study of metronomic oral chemotherapy with cyclophosphamide plus capecitabine and vinorelbine in metastatic breast cancer patients"). Patients received vinorelbine 40 mg orally on days 1, 3 and 5 every week, cyclophosphamide 50 mg daily and capecitabine 500 mg 3 times a day.
Given the promising activity of the VEX regimen in a pre-treated population of advanced breast cancer patients and the good tolerability, the aim of the present trial is to investigate whether the VEX schedule may improve efficacy and tolerability as compared to standard paclitaxel treatment in advanced or metastatic ER-positive/HER2-negative breast cancer patients.
The concept of the VEX metronomic treatment is to administer the combination for as long as the patient has the possibility of deriving a benefit from it. The time to treatment failure (TTF) has been chosen as primary endpoint for this trial. TTF is defined as time from the date of randomization to the date when the final dose of trial treatment is administered. Chemotherapy may need to be stopped due to lack of tolerability, lack of efficacy or patient preference through subjective symptom assessment. TTF is a composite endpoint combining all these feasibility aspects of a treatment. It is therefore uniquely suited to the research question of the current trial. The secondary endpoints progression-free survival, disease control and safety will allow further assessment of the feasibility of the VEX metronomic treatment versus the paclitaxel monotherapy regimen.

Outcome Measures
Primary Outcome Measures
- Time to treatment failure (TTF) compared between treatment groups. [From date of randomization until the date the final dose of trial treatment was given due to documented progression, lack of tolerability or until further treatment is declined, assessed up to 36 months from enrollment of the first patient.]
Efficacy and tolerability, measured by time to treatment failure, of metronomic oral vinorelbine plus cyclophosphamide and capecitabine (VEX) versus weekly paclitaxel, using an intent-to-treat analysis approach.
Secondary Outcome Measures
- Frequency of targeted adverse events (safety and tolerability). [Time from day 1 of cycle 1 until 28 days after stopping trial treatment.]
Frequency of adverse events by type and worst grade experienced.
- Disease control [From date of randomization until the date of first documented progression, assessed up to 36 months from enrollment of the first patient.]
Best overall response of complete response (CR) or partial response (PR), or stable disease (SD) lasting for at least 24 weeks, measured from randomisation to progression.
- Progression free survival (PFS) [Time from randomization until documented disease progression, assessed up to 36 months from the enrollment of the first patient.]
Distribution of PFS for each treatment group using Kaplan-Meier; median PFS with two-sided 95% confidence interval (CI). PFS according to RECIST 1.1 criteria or death, whichever occurs first.
- Overall Survival [From day 1 of cycle 1 until death from any cause (censored at date of last assessment of vital status for patients lost to follow up), assessed up to 36 months from the enrollment of the first patient.]
Overall survival from time of randomisation will be summarised for each treatment group.
