Brief Summary:
This is a 3 part study for patients with solid tumours. The purpose of Part A is to measure the amount of olaparib or its breakdown products in the bloodstream for up to 72 hours after eating and the effect of olaparib on QT interval following a single oral dose of olaparib tablets. Part B will determine the effect of olaparib on the QT interval following multiple oral dosing. Part C will allow patients continued access to olaparib tablets and will provide additional safety data collection.
