- Procedure: Pharmacokinetic samplingOther: Dietary High FatOther: Dietary Fasted
- Registration Number
- NCT01921140
- Lead Sponsor
- AstraZeneca
- 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.

- Secondary Outcome Measures
Name Time Method To assess the safety and tolerability of olaparib following oral dosing Part A&B: Adverse events (AEs) will be collected from the time of signed informed consent up to and including the 30-day follow-up period. In Part C, AEs will be collected for 12 months 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.
Assessment of AEs, graded by CTCAE (v4.03),To assess safety and tolerability of oral olaparib dosing Laboratory and vital sign assessments will be carried out at baseline and then at every scheduled visit until 30 days post last dose Assessment of AEs, graded by CTCAE (v4.0), physical examination, vital signs (including BP and pulse), standard 12-lead ECG and evaluation of laboratory parameters (clinical chemistry, haematology, and urinalysis). Assessment of physical examination, vital signs, ECG and evaluation of laboratory parameters 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 electrocardiogram (ECG) intervals (including QT and QTc interval) Digital ECG's will be recorded at Day-1, Day 1 of both treatment periods in Part A at: pre-dose, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, and 24 hours post olaparib dose. Part B Day -1 & Day 5: pre-dose, 1, 1.5, 2, 3, 4, 6, 8, & 12 hours post dose. The QT interval uncorrected and corrected for heart rate (QTc) following single (Part A) and multiple (Part B) oral doses of olaparib tablet formulation.
