A Study to Evaluate Safety and Efficacy of Caelyx in Combination With Cyclophosphamide in the Treatment of Metastatic Breast Cancer (P02948)
- Conditions
- Breast Neoplasm
- Interventions
- Registration Number
- NCT00779129
- Lead Sponsor
- Merck Sharp & Dohme LLC
- Brief Summary
Women with metastatic breast cancer are usually treated with anthracyclines (ie, doxorubicin or epirubicin) but cardiac toxicity limits their use. The aim of this study is to evaluate the safety and efficacy of Caelyx in combination with cyclophosphamide in women with metastatic breast cancer who have received adjuvant anthracyclines with or without a taxane.
