Experimental: Caelyx, Docetaxel, Trastuzumab
Stage 1: subjects will receive Caelyx one day every 3 weeks in combination with docetaxel one day every 3 weeks and trastuzumab once weekly during 6 cycles. At the end of this stage, based on the number of cardiac events, subjects will proceed to a second stage or restart with a lower dose of Caelyx.
Stage 2: subjects will be treated with the recommended dose of Caelyx (defined in the first stage) in combination with docetaxel and trastuzumab.
Drug: Pegylated Liposomal Doxorubicin
Stage 1: 25 subjects will be treated with Caelyx IV 30 mg/m^2 on day 1, every 3 weeks
Stage 2: 45 new patients will be treated at the recommended dose level (defined in the first step) on day 1, every 3 weeks.
Other Name: CaelyxDrug: Docetaxel
Stage 1 and Stage 2: Docetaxel 60 mg/m2 IV as 1-hour infusion, on day 1, every 3 weeks.
Other Name: TaxotereDrug: Trastuzumab
Stage 1 and Stage 2: 4 mg/kg IV 90-minute infusion loading dose. Then 2 mg/kg IV weekly during 6 cycles (18 weeks).
