Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This 2 arm study will compare the efficacy and safety of continuation or discontinuation of Herceptin treatment in combination with 2nd line chemotherapy, in patients with HER2 positive metastatic breast cancer whose condition has progressed on 1st line chemotherapy plus Herceptin. Patients will be randomized either to continue or discontinue Herceptin treatment (2mg/kg iv infusion weekly, or 6mg/kg iv infusion every 3 weeks) while receiving 2nd line chemotherapy of the investigator's choice. The anticipated time on study treatment is until disease progression, and the target sample size is 100-500 individuals.
