PurposeCediranib is a potent multitargeted inhibitor of vascular endothelial growth factor receptor (VEGFR) 1, 2 and 3. The study was initiated to evaluate the activity of cediranib in patients (pts) with recurrent ovarian, peritoneal or fallopian tube cancer (OC).MethodsEligible pts had persistent/recurrent OC following one prior platinum-based chemotherapy with measurable disease or progression based on Gynecologic Cancer Inter Group CA-125 criteria. Because of toxicities observed in the first 23 pts, the initial starting dose of oral daily (od) cediranib was reduced from 45mg to 30mg. The primary endpoint was objective response rate at 16weeks. This study was stratified into two arms: platinum-sensitive (PL-S) and platinum-resistant (PL-R).Results74 pts were enrolled; 39 were PL-S and 35 PL-R, with a median age of 58years [31-87]. In PL-S group, 10 (26%) partial responses (PR) and 20 (51%) stable disease (SD) were confirmed while in the PL-R arm there were no confirmed PR and 23 pts (66%) had SD. The main grade 3/4 toxicities observed at the 30 mg starting dose were hypertension (27%), fatigue (20%) and diarrhea (14%). The median progression-free survival for all patients was 4.9months [3.9-7.0], 7.2months [4.3-9] for PL-S and 3.7months [2.6-4.5] for PL-R groups. The median overall survival was 18.9months (95% CI: 13.5-31.5); 27.7months [17.8-43.3] for PL-S and 11.9months [8.1-18.9] for PL-R groups.ConclusionCediranib shows significant activity in recurrent platinum sensitive OC. The toxicities were expected and manageable at the dose of 30mg od.Copyright © 2015 Elsevier Inc. All rights reserved.
