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.
