Brief Summary

The purpose of this study is to evaluate, in a first stage, the safety (incidence of cardiac toxicity) of Caelyx in combination with Trastuzumab and Docetaxel; and in a second stage, the tumor response rate of this regimen. This study will be conducted in approximately 30 centers. A total of approximately 70 to 95 subjects will be enrolled.

Conditions

Breast Neoplasm

Outcome Measures

Primary Outcomes (1)

• Number of Participants Who Had a Tumor Response, According to Standard RECIST (Response Evaluation Criteria in Solid Tumors) Criteria

  Those who achieved either complete (disappearance of all target lesions) or partial (at least 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD) response.

  Week 09, Week 18, at the end of each patient's treatment, and at 3, 6, 9, and 12 months after end of treatment.

Study Arms (1)

Caelyx, Docetaxel, Trastuzumab

EXPERIMENTAL

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; Drug: Docetaxel; Drug: Trastuzumab

Interventions

Pegylated Liposomal Doxorubicin DRUG

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.

Also known as: Caelyx

Caelyx, Docetaxel, Trastuzumab

Docetaxel DRUG

Stage 1 and Stage 2: Docetaxel 60 mg/m2 IV as 1-hour infusion, on day 1, every 3 weeks.

Also known as: Taxotere

Caelyx, Docetaxel, Trastuzumab

Trastuzumab DRUG

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).

Caelyx, Docetaxel, Trastuzumab
