Background/Purpose This study was designed to evaluate the response and toxicity of sorafenib alone or when combined with carboplatin and paclitaxel in patients with platinum-sensitive, recurrent ovarian cancer, fallopian tube cancer, or primary peritoneal cancer (EOC). Methods Patients with recurrent platinum-sensitive EOC with no more than 2 prior courses of chemotherapy were randomized to single-agent sorafenib 400 mg twice daily or combination sorafenib 400 mg bid (days 2–19) with IV carboplatin (AUC 6) and IV paclitaxel 175 mg/m2 (S+C/T) every 3 weeks. Single agent sorafenib could cross over to combination upon progression. Results Patients were initially randomized to either arm, however, due to poor accrual, sorafenib arm was prematurely closed. A total of 13 patients were evaluable for response to sorafenib and 23 patients were evaluable for response to S+C/T. Objective response rate (RR) was 15 % for patients on sorafenib vs. 61 % for patients on S+C/T (p = 0.014); stable disease was seen in 62 % and 35 %, respectively. Clinical benefit rate (CBR) at 4 months (mos.) was 69 % for S and 65 % for S+C/T. The median progression free survival was 5.6 months on sorafenib vs. 16.8 months on S+C/T (p = 0.012) and there was no significant difference of overall survival between two arms (p = 0.974) with median overall survival 25.6 months under sorafenib vs. 25.9 months on S+C/T. Patients remained on trial for a median of 7.8 cycles on sorafenib and 5.4 cycles on S+C/T. Conclusion Sorafenib, alone or in combination with carboplatin and paclitaxel, has activity in patients with platinum-sensitive EOC. Sorafenib in combination with carboplatin and paclitaxel improved RR and PFS; however, there were increased grade and frequencies of toxicities.
