Primary Outcome Measures:
  • Cardiotoxicity (definite or probable cardiac death) [ Time Frame: treatment period ]
  • Signs or symptoms of congestive heart failure (CHF), New York Heart Association (NYHA) class III-IV [ Time Frame: treatment period ]
  • 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 ]
  • Decline in LVEF of ≥ 10% to < 50% without signs or symptoms of CHF [ Time Frame: treatment period ]

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 ]
  • Response rate [ Time Frame: treatment period ]
  • Median time to progression [ Time Frame: treatment period ]
  • Progression free survival [ Time Frame: treatment period ]

Enrollment: 70
Study Start Date: May 2006
Study Completion Date: July 2011
Primary Completion Date: November 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1.
Drug: Non pegylated liposomal doxorubicin and docetaxel
max. 6 courses
Other Name: Myocet, Taxotere

Detailed Description:

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

Myocet and Taxotere will be given for a maximum of 6 cycles. 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   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:
