This is a 3-part study in patients with advanced solid tumours: Part A will assess the effect of itraconazole on the PK parameters of olaparib and will determine the effect of olaparib on the QT interval following single oral dosing; 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 after the PK and QT phases and will provide for additional safety data collection. A total of 48 patients are planned to be enrolled; at least 42 evaluable patients will be required to complete the study. Patients will participate as a single cohort in all parts of the study.

Assessment of the time between the start of the Q wave and the end of the T wave in the heart's electrical cycle (the QT interval), uncorrected and corrected for heart rate (QTc) following single (Part A) and multiple (Part B) oral doses of olaparib tablet formulation.

Assessment of adverse events (AEs), graded by CTCAE (v4.0): Adverse events (AEs) will be collected from the time of signed informed consent throughout the treatment period in Part A and Part B up to and including the 30-day follow-up period. In Part C, AEs will be collected until 12 months after the last patient entered Part C, and including the 30 day follow-up period for any patients who discontinue

These will occur at screening, on the day before dosing in each treatment period and 30 days after last dose in Parts A and B. In Part C, will be assessed weekly for a 28-day period followed by every 4 weeks up to 12 months after the last patient enters Part C and at treatment discontinuation. All will be assessed 30 days after last dose.

Assessment of vital signs (including BP and pulse). These will occur at screening, on the day before dosing in each treatment period and 30 days after last dose in Parts A and B. In Part C, all except ECG will be assessed weekly for a 28-day period followed by every 4 weeks up to 12 months after the last patient enters Part C and at treatment discontinuation. All will be assessed 30 days after last dose.

Assessment of laboratory parameters (clinical chemistry, hematology, and urinalysis) : These will occur at screening, on the day before dosing in each treatment period and 30 days after last dose in Parts A and B. In Part C, all except ECG will be assessed weekly for a 28-day period followed by every 4 weeks up to 12 months after the last patient enters Part C and at treatment discontinuation. All will be assessed 30 days after last dose.
