A Study of Liposomal Doxorubicin+Docetaxel+Trastuzumab+Metformin in Operable and Locally Advanced HER2 Positive Breast Cancer
- Conditions
- HER-2 Positive Breast Cancer
- Interventions
- Registration Number
- NCT02488564
- Brief Summary
It is a multicenter, open-label, two stage phase II trial, to assess activity, safety and potential early predictors of response in neoadjuvant setting. Patients with operable breast cancer (T1c and cytologically N1-2, or cT2-3, N0-N2, M0) or locally advanced breast cancer (T4a-d, N0-N2, M0) with overexpression or amplification of HER2 (AJCC 7th edition 2010) are included in the study.
The primary objective is to evaluate the pathological complete response rate (pCR).
The secondary objectives are:
* to evaluate the clinical response rate (RR).
* to evaluate the feasibility and systemic tolerance, with particular attention to cardiac toxicity.
* to evaluate the conservative surgery rate.
Total duration of the trial is 36 months; planned treatment are 6 cycles of chemotherapy. At every cycle (every 21 days) will be administered:
Day 1: Liposome-encapsulated doxorubicin, 50 mg/m2 IV 1 hour infusion; Day 2 and 9: Docetaxel, 30 mg/m2 IV 1 hour infusion; Day 2, 9 and 16: Trastuzumab 4 mg/kg for the first infusion loading dose, then 2 mg/kg/week for subsequent injections. Day -13 to 0: Metformin is administered as single agent. From day -13 to day -11, Metformin 1000 mg will be administered once a day; from day -10 Metformin 1000 mg will be administered twice a day continuously until end of the study treatment.
- Detailed Description
Multi-center, open-label phase II trial to assess activity of this chemotherapy scheme evaluated by pathologic complete response rate (pCR).
Planned treatment are 6 cycles of chemotherapy.
At every cycle (every 21 days) will be administered:
Day 1: Liposome-encapsulated doxorubicin, 50 mg/m2 IV 1 hour infusion; Day 2 and 9: Docetaxel, 30 mg/m2 IV 1 hour infusion; Day 2, 9 and 16: Trastuzumab 4 mg/kg for the first infusion loading dose, then 2 mg/kg/week for subsequent injections Day -13 to 0: Metformin is administered as single agent. From day -13 to day -11, Metformin 1000 mg will be administered once a day; from day -10 Metformin 1000 mg will be administered twice a day continuously until end of the study treatment.
Total duration of the trial: 36 months Enrollment period: 24 months Treatment: maximum of 6 cycles (5 months) per patient Follow-up for recurrence: every six months for 5 years, than once a year until 10 years after surgery.It's necessary to recruit 46 patients for clinical objectives evaluation.

- Primary Outcome Measures
Name Time Method Pathologic complete response rate(pCR) up to 36 months Complete pathologic response will be defined as no invasive residuals in breast and axillary nodes. In situ tumor residuals are considered as complete response rate
- Secondary Outcome Measures
Name Time Method clinical response rate (RR) up to 36 months The clinical response rate (RR) will be including Pathological Complete Response, Clinical Complete Response and Clinical Partial Response (Response Evaluation Criteria in Solid Tumors (RECIST) criteria).
