Phase II study of pegylated liposomal doxorubicin and oxaliplatin in relapsed advanced ovarian cancer

OBJECTIVE: This phase II study evaluated the efficacy and safety of pegylated liposomal doxorubicin (PLD) 30 to 35 mg/m(2) plus oxaliplatin 70 mg/m(2) every 28 days in women with advanced ovarian cancer that recurred or progressed after a platinum-based regimen. METHODS: 43 women received a median of 6 courses of treatment. RESULTS: Objective response was 54% in the evaluable population and was higher in women with platinum-sensitive (67%) compared with platinum-resistant disease (29%). At a median duration of follow-up of 15.5 months, median overall survival was 15.8 months and time to tumor progression 7.3 months. Most toxicity was no greater than grade 1 or 2. There was no grade 3 or 4 palmar-plantar erythrodysesthesia. After 264 cycles administered, neutropenia was the most common cause of severe toxicity and required one patient to withdraw from the study. No cardiotoxicity was reported. CONCLUSION: PLD plus oxaliplatin is active and well tolerated in women with relapsed advanced ovarian cancer, regardless of platinum sensitivity.
