Cediranib (AZD2171, RECENTIN™) in Addition to Chemotherapy in Patients With Untreated Metastatic Colorectal Cancer

Number of months from randomisation to the date of death from any cause

Time frame: Baseline through to date of death upto and including data cut off date of 21/03/10

Population: Two cediranib doses (20 mg and 30 mg) were initially included in this study; however, it was intended that one dose would be selected for continuation. The decision was taken to continue with cediranib 20 mg. All efficacy analyses compared cediranib 20mg to placebo. No statistical analyses were performed on the 30mg group.

RECIST criteria defined as follows: Target lesions Complete Response (CR) Disappearance of all target lesions Partial Response (PR) At least a 30% decrease in the sum of LD of target lesions taking as reference the baseline sum LD.Progressive Disease (PD) At least a 20% increase in the sum of LD of target lesions taking as references the smallest sum LD recorded (either at baseline or at previous assessment since treatment began).Stable Disease (SD) Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD. Non-target lesions Complete Response (CR) Disappearance of all non-target lesions Non-Complete Response (non-CR/Non- Progression \[non-PD\]) Persistence of one or more non-target lesion or/and maintenance of tumour marker level above the normal limits. Progression (PD) Unequivocal progression of existing nontarget lesions.

Time frame: RECIST assessed at baseline every 6 weeks through to week 24 and 12 week thereafter through to progression or data cut off date of 21/03/10 whichever was earliest.

Maximum percentage reduction or minimum percentage increase in tumour size where size is the sum of the longest diameters of the target lesions

Time frame: Baseline through to date of death upto and including data cut off date of 21/03/10

The decision was taken to continue with cediranib 20 mg. All efficacy analyses compared cediranib 20mg to placebo. No statistical analyses were performed on the 30mg group.

Based on RECIST measurements taken throughout the study and best objective tumour response at the defined analysis cut-off point. Measured from the time the criteria for CR/PR are first met (whichever is recorded first) until the patient progresses or dies.

Time frame: Treatment period from initial response up until data cut-off date of 21/03/10

The decision was taken to continue with cediranib 20 mg. All efficacy analyses compared cediranib 20mg to placebo. No statistical analyses were performed on the 30mg group.

Objective tumour response(defined as a confirmed response of CR or PR).The definition for a confirmed response was met when an initial RECIST response of PR/CR was confirmed at the next scheduled visit as a PR/CR according to an evaluable assessment.Intervening assessments of non-evaluable or stable disease were allowable as long as the initial RECIST response was confirmed.RECIST criteria defined as follows: Target lesions Complete Response(CR)Disappearance of all target lesions Partial Response (PR).At least a 30% decrease in the sum of LD of target lesions taking as reference the baseline sum LD. Progressive Disease (PD) At least a 20% increase in the sum of LD of target lesions taking as references the smallest sum LD recorded (either at baseline or at previous assessment since treatment began).Stable Disease (SD) Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD.Non-target lesions Complete Response (CR) Disappearance of all non-target lesi

Number of patients undergoing liver resection, based on patients with liver disease at baseline

Time frame: Post-randomisation until end of study

Population: Two cediranib doses (20 mg and 30 mg) were initially included in this study; however, it was intended that one dose would be selected for continuation. The decision was taken to continue with cediranib 20 mg. All efficacy analyses compared cediranib 20mg to placebo. No statistical analyses were performed on the 30mg group.
