OV.18 (MRC ICON6) - A Randomised, Placebo-Controlled, Trial of Concurrent Cediranib [AZD2171] (with platinum-based chemotherapy) and Concurrent and Maintenance Cediranib in Women with Platinum-sensitive Relapsed Ovarian Cancer

OV.18 (MRC ICON6) was a randomized, three-arm, double-blind, placebo-controlled phase 3 trial that randomly assigned patients aged 18 years or older with relapsed platinum-sensitive ovarian cancer. Participants received up to six cycles of platinum-based chemotherapy (once every 3 weeks) then entered a maintenance phase. Participants were randomly allocated to receive placebo alongside chemotherapy and then placebo only maintenance (arm A), cediranib 20 mg once-daily alongside chemotherapy then placebo only maintenance (arm B), or cediranib 20 mg once-daily alongside chemotherapy then cediranib 20 mg once-daily maintenance (arm C).

Centres in Australia, Canada, New Zealand, Spain, and the UK enrolled 486 women between November 2007 and December 2011.

The results of the study showed that cediranib, when given orally with chemotherapy and continued as maintenance, yielded a meaningful improvement in progression-free survival in women with recurrent platinum-sensitive ovarian cancer, albeit with added toxic effects. The positive results in ICON6 could provide women with a new therapeutic option for recurrent ovarian cancer. Assessment of the secondary endpoint of overall survival will need longer follow-up.
