Abstract

Objective: To assess the efficacy and safety of dose-dense weekly paclitaxel plus carboplatin (ddTC) with or without bevacizumab compared to conventional, tri-weekly paclitaxel plus carboplatin (cTC) with or without bevacizumab, in metastatic or recurrent cervical carcinoma not amenable to curative local therapy. Methods: Patients were randomly assigned to either the cTC or ddTC arm. The cTC regimen was paclitaxel 175 mg/m2 and carboplatin at an area under the curve (AUC) of 5 on day 1. The ddTC regimen was paclitaxel 80 mg/m2 on day 1, 8, 15 and carboplatin at AUC of 5 on day 1. Both cTC and ddTC treatments were repeated every 3 weeks for up to 9 cycles. After bevacizumab was approved in Japan, patients in both arms received bevacizumab 15 mg/kg if not contraindicated. The primary endpoint of phase II part was response rate (RR). If the RR of ddTC+bevacizumab was found to be at least 5% better than to cTC + bevacizumab, the study would proceed to phase III part, which had overall survival as its primary endpoint. Clinical trial information: jRCTs031180007. Results: In total, 122 patients were randomly assigned to either the cTC arm (cTC + bevacizumab: 32; cTC:29) or the ddTC arm (ddTC+bevacizumab: 30; ddTC:31). The RR for patients on cTC + bevacizumab was 67.9%, and for patients on ddTC+bevacizumab 60.7%, cTC: 55.2%, and ddTC: 50.0%. Conclusions: The study did not meet the primary endpoint of phase II portion. Dose-dense, weekly paclitaxel plus carboplatin is not promising for metastatic or recurrent cervical carcinoma.
