The primary endpoint is survival. The study is designed to be pragmatic, limiting additional study related investigations to a minimum. Protocol mandated scans and X-rays are limited to two time points (baseline and week 26) to permit comparison of the percentage of patients with progressive disease at 6 months as a secondary efficacy endpoint. Six months was selected based on review of published literature indicating that progressive disease was commonly observed by 26 weeks in patients with renal cancer. Endpoints such as tumour response by RECIST are considered of secondary importance to survival and will be determined by radiological examinations ordered at the discretion of the investigator based on the clinical status of the patient and will be based the interpretation of the patient's care-team (investigator and local radiologist).
