An RCT of Concurrent and Maintenance Cediranib in Women With Platinum-sensitive Relapsed Ovarian Cancer

ICON6 is a randomised three-arm, two stage, double-blind, placebo-controlled multicentre Gynaecologic Cancer InterGroup (GCIG) phase III trial. All patients will receive 6 cycles of platinum-based chemotherapy. Trial drug will be administered for up to 18 months from randomisation or until progression, whichever is sooner. Patients who have not progressed at 18 months from randomisation can continue Trial Drug until progression, if in the opinion of the clinician and the patient there is continuing clinical benefit. Patients in Arm A (the reference arm) will receive a platinum-based chemotherapy regimen plus a daily oral placebo tablet for the duration of the chemotherapy and up to 18 months from randomisation or until progression. Patients in Arm B (concurrent cediranib arm) will also receive a platinum-based chemotherapy regimen plus daily oral cediranib during chemotherapy only, and then an oral daily placebo tablet up to 18 months from randomisation or until progression. Patients in Arm C (concurrent and maintenance cediranib arm) will also receive a platinum-based chemotherapy regimen plus oral cediranib daily during chemotherapy and then continued up to 18 months from randomisation or until progression.
