A Study to Evaluate the Safety and Efficacy of Caelyx in Combination With Carboplatin in Patients With Ovarian Cancer Recurrent Within Six to Twelve Months After Initial Carboplatin and Paclitaxel Chemotherapy (P03625)(COMPLETED)

Doxorubicin has been used to treat ovarian cancer as part of different combination therapies, but high cumulative doses should be avoided because of the risk of cardiotoxicity. Pegylated Lyposomal Doxorubicin (Caelyx) has been developed to reduce the risk of cardiotoxicity. The purpose of this study is to evaluate the safety and efficacy of Caelyx in combination with carboplatin in women with recurrent ovarian cancer.

• Drug: Pegylated Lyposomal Doxorubicin
  Subjects will receive Caleyx 30 mg/m2 intravenously on Day 1 of each 4-week cycle, during 6 cycles. Patients still achieving clinical benefit after a total of 6 cycles may continue therapy.
  Other Name: SCH 200746
• Drug: Carboplatin
  Subjects will receive carboplatin dosed to target AUC of 5 mg/mL.min, intravenously, on Day 1 of each 4-week cycle, after the Caelyx infusion, during 6 cycles. Patients still achieving clinical benefit after a total of 6 cycles may continue therapy.
