Phase 2
Completed
Conditions
Colorectal Cancer
Interventions
Registration Number
NCT00912743
Lead Sponsor
AstraZeneca
Brief Summary

This study is being carried out to see if the new drug, olaparib (AZD2281), can effectively and safely treat advanced large bowel cancer. The primary goal of this clinical trial is to determine whether olaparib will have a beneficial effect on the patient's cancer by causing a response and increasing the time it takes for the cancer to progress.

Primary Outcome Measures
NameTimeMethod
Tumour ResponseFrom baseline, i.e. up to 28 days before first study drug dose, and then every 2 cycles (8 weeks) up to objective disease progression by RECIST, assessed up to 35 months

Tumour response is the number of patients who experienced complete or partial response at least once during the assessment period, according to the definitions of Response Evaluation Criteria In Solid Tumours (RECIST version 1.1)

Secondary Outcome Measures
NameTimeMethod
Progression Free SurvivalFrom baseline, i.e. up to 28 days before first study drug dose, and then every 2 cycles (8 weeks) up to objective disease progression by RECIST, assessed up to 35 months

Progression free survival is defined as the duration from first dose till objective progression or death. In absence of progression or death, the time is calculated from first dose till last evaluable scanning visit.

Overall SurvivalSurvival follow-up from first dose till death of the patient or till end of study in absence of death, assessed up to 35 months

Overall survival is defined as the duration from first dose till death from any cause. In absence of death, the time is calculated from first dose till the date subject last known to be alive
