Abstract

BACKGROUND:

Cediranib is a highly potent vascular endothelial growth factor (VEGF) signalling inhibitor with activity against VEGF receptors 1, 2 and 3. This Phase II, randomised, double-blind, parallel-group study compared the efficacy of cediranib with placebo in patients with metastatic or recurrent clear cell renal cell carcinoma who had not previously received a VEGF signalling inhibitor.

METHODS:

Patients were randomised (3:1) to cediranib 45 mg/day or placebo. The primary objective was comparison of change from baseline in tumour size after 12 weeks of therapy. Secondary objectives included response rate and duration, progression-free survival (PFS) and safety and tolerability. Patients in the placebo group could cross over to open-label cediranib at 12 weeks or earlier if their disease had progressed. This study has been completed and is registered with ClinicalTrials.gov, number NCT00423332.

FINDINGS:

Patients (n=71) were randomised to receive cediranib (n=53) or placebo (n=18). The primary study outcome revealed that, after 12weeks of therapy, there was a significant difference in mean percentage change from baseline in tumour size between the cediranib (-20%) and placebo (+20%) arms (p<0.0001). Eighteen patients (34%) on cediranib achieved a partial response and 25 (47%) experienced stable disease. Cediranib treatment prolonged PFS significantly compared with placebo (hazard ratio (HR)=0.45, 90%confidence interval: 0.26-0.76, p=0.017; median PFS 12.1 versus 2.8 months). The most common adverse events in patients receiving cediranib were diarrhoea (74%), hypertension (64%), fatigue (58%) and dysphonia (58%).

INTERPRETATION:

Cediranib monotherapy demonstrated significant evidence of antitumour activity in patients with advanced renal cell carcinoma. The adverse event profile was consistent with previous studies of cediranib 45 mg.
