  • the present invention is in the field of treatment for metastatic breast cancer in an individual who has previously been administered an anthracycline.
  • Doxorubicin is one of the most active and versatile anticancer agents. It has an exceptionally broad spectrum of activity and plays a leading role in the curative and palliative therapy of a diverse group of malignancies, most notably breast cancer, lymphoma, soft tissue sarcoma, various pediatric malignancies, multiple myeloma, and advanced bladder cancer.
  • doxorubicin is associated with serious and sometimes life threatening side effects.
  • doxorubicin's use is limited by the potential for patients to suffer irreversible cardiotoxicity. The incidence of clinically significant cardiomyopathy or congestive heart failure rises with increasing lifetime cumulative doses of doxorubicin.
  • Doxorubicin and trastuzumab are known to be cardiotoxic, and their concomitant combined use presents a significant risk of cardiotoxicity.
  • the risk of cardiotoxicity from treatment with doxorubicin and trastuzumab is believed to be enhanced for patients who have received prior treatment with an anthracycline.
