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.

Conditions

  • HER-2 Positive Breast Cancer

Interventions

DRUG

Liposomal doxorubicin

50 mg/m2 by intravenous infusion over a period of 1 hour on day 1 of each cycle repeated every 21 days. A final concentration of between 0.4 to 1.2 mg/ml doxorubicin hydrochloride, is required

DRUG

Docetaxel

30 mg/m2 by intravenous infusion over a period of 1 hour on day 2 and 9, every 3 week.They will be given for 6 cycles.

DRUG

Trastuzumab

4 mg/kg for the first administration (day 2 cycle 1) and 2 mg/kg for subsequent administrations. Trastuzumab will be given weekly for the duration of chemotherapy (day 2, 9, 16), then will be administered at the dose of 6 mg/Kg every 3 weeks until completion of 52 weeks of treatment.

DRUG

Metformin

It is administered as single agent from day -13 to 0. 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.
