A phase II trial of oxaliplatin, docetaxel, and bevacizumab as first-line therapy of advanced cancer of the ovary, peritoneum, and fallopian tube.

OBJECTIVE: To determine the safety and efficacy of the novel combination of docetaxel, oxaliplatin, and bevacizumab as first-line treatment of advanced cancer of the ovary, peritoneum or fallopian tube after initial debulking surgery. METHODS: Eligible patients (stage IB-IV) were treated with 6 cycles of oxaliplatin (85 mg/m(2)), docetaxel (75 mg/m(2)), and bevacizumab (15 mg/kg) every 3 weeks, followed by single-agent bevacizumab 15 mg/kg every 3 weeks to complete one year of therapy. The primary endpoint was 12-month progression-free survival (PFS). RESULTS: A total of 132 patients (80 with measurable disease at baseline; 52 with non-measurable, evaluable disease at baseline) enrolled and received study treatment. At diagnosis, 76.5% of patients had stage III disease and 20% had stage IV. 62.9% were optimally cytoreduced. The most common grade 3/4 adverse events were neutropenia (42.4%), leukopenia (13.6%), hypertension (8.3%), fatigue (6.1%), and nausea (6.1%). One patient (0.8%) had a fatal gastrointestinal perforation. The best overall confirmed response rate (complete response+partial response [measurable disease subgroup]) was 58.6% (95% CI 49%, 67%). CA-125 response rates for the measurable and non-measurable disease subgroups were 83.0% and 81.5%, respectively. The 12-month PFS rate for the measurable disease subgroup was 65.7% (95% CI 53.4%, 76.7%); median PFS was 16.3 (95% CI 12.6, 19.6) months. Median overall survival was 47.3 (95% CI 34.1, upper limit not applicable) months. CONCLUSIONS: This novel treatment regimen may provide a promising therapeutic approach for women with ovarian, primary peritoneal, or fallopian tube carcinoma. No unanticipated safety concerns were identified.
