OBJECTIVES: The aim of this phase II study was to assess the benefits of a weekly administration of topotecan and gemcitabine in patients with ovarian carcinoma having relapsed after platinum/taxane-based first-line chemotherapy.
METHODS: Seventy-seven patients with progression of disease</=12 months after first-line chemotherapy were enrolled to receive topotecan (2.5 mg/m(2)) and gemcitabine (1000 mg/m(2)) on days 1, 8 and 15 (q 28 d). Primary endpoint was the response rate. Stabilization rate and symptom improvement were also assessed.
RESULTS: All patients received the combination and 66 were evaluable (>/=2 cycles administered). The only major severe toxicity was neutropenia grades 3 (17%) and 4 (6%). Approximately 60% of the patients received the complete schedule of treatment, dose interruptions/delays being mainly due to moderate thrombocytopenia or neutropenia. The objective response rate was 14%, the values for patients having relapsed within 6 (n=30) and 6-12 (n=36) months being 7%and 20%, respectively. Median durations of response were 4.9 and 6.4 months and clinical benefit rates including stabilizations reached 63% and 69% in patients having relapsed within 6 or 6-12 months, respectively. Corresponding median overall survival was 7.5 and 15.6 months. Symptoms and pain were reduced in 64% and 39% of the patients concerned, respectively.
CONCLUSION: In early relapse ovarian cancer, weekly combination of gemcitabine and topotecan has a modest objective response rate. However, a high proportion of patients experienced stable disease and symptom control leading to acceptable quality of life.

PURPOSE: The objective of this study was to compare the efficacy and safety of trabectedin plus pegylated liposomal doxorubicin (PLD) with that of PLD alone in women with recurrent ovarian cancer after failure of first-line, platinum-based chemotherapy.
PATIENTS AND METHODS: Women>or = 18 years, stratified by performance status (0 to 1 v 2) and platinum sensitivity, were randomly assigned to receive an intravenous infusion of PLD 30 mg/m(2) followed by a 3-hour infusion of trabectedin 1.1 mg/m(2) every 3 weeks or PLD 50 mg/m(2) every 4 weeks. The primary end point was progression-free survival (PFS) by independent radiology assessment.
RESULTS: Patients (N = 672) were randomly assigned to trabectedin/PLD (n = 337) or PLD (n = 335). Median PFS was 7.3 months with trabectedin/PLD v 5.8 months with PLD (hazard ratio, 0.79; 95% CI, 0.65 to 0.96; P = .0190). For platinum-sensitive patients, median PFS was 9.2 months v 7.5 months, respectively (hazard ratio, 0.73; 95% CI, 0.56 to 0.95; P = .0170). Overall response rate (ORR) was 27.6% for trabectedin/PLD v 18.8% for PLD (P = .0080); for platinum-sensitive patients, it was 35.3% v 22.6% (P = .0042), respectively. ORR, PFS, and overall survival among platinum-resistant patients were not statistically different. Neutropenia was more common with trabectedin/PLD. Grade 3 to 4 transaminase elevations were also more common with the combination but were transient and noncumulative. Hand-foot syndrome and mucositis were less frequent with trabectedin/PLD than with PLD alone.
CONCLUSION: When combined with PLD, trabectedin improves PFS and ORR over PLD alone with acceptable tolerance in the second-line treatment of recurrent ovarian cancer.
