Primary Outcome Measures:
  • Cardiotoxicity (definite or probable cardiac death) [ Time Frame: treatment period ] [ Designated as safety issue: Yes ]
  • Signs or symptoms of congestive heart failure (CHF), New York Heart Association (NYHA) class III-IV [ Time Frame: treatment period ] [ Designated as safety issue: Yes ]
  • Decline in left ventricular ejection fraction (LVEF) of ≥ 5% to < 50% with mild signs or symptoms of CHF (NYHA class < III) [ Time Frame: treatment period ] [ Designated as safety issue: Yes ]
  • Decline in LVEF of ≥ 10% to < 50% without signs or symptoms of CHF [ Time Frame: treatment period ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Frequency and severity of intercurrent events according to the National Cancer Institute - Common Terminology Criteria (NCI-CTC) classification [ Time Frame: treatment period ] [ Designated as safety issue: Yes ]
  • Response rate [ Time Frame: treatment period ] [ Designated as safety issue: No ]
  • Median time to progression [ Time Frame: treatment period ] [ Designated as safety issue: No ]
  • Progression free survival [ Time Frame: treatment period ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: 1
Myocet + docetaxel + trastuzumab
Drug: Non pegylated liposomal doxorubicin, trastuzumab, docetaxel
max. 6 courses
Other Name: Myocet, herceptin, toxotere

Detailed Description:

Phase II non comparative study, assessing the safety (primarily cardiac safety) and efficacy in patients with locally advanced or metastatic HER2/neu positive breast cancer not yet treated with chemotherapy for metastatic disease.

Myocet and Taxotere will be given for a maximum of 6 cycles, Herceptin treatment for 1 year is recommended.

Endpoints: cardiotoxicity (left ventricular ejection fraction decrease and/or symptoms of heart failure), serious other toxicity, disease progression.


Ages Eligible for Study:   18 Years and older
