On Day 1 of each period, patients will receive a single dose of either Tablet A, B, C, or D, according to the randomization schedule. Serial blood samples for determination of olaparib in plasma will be collected for 72 hours.

This is a phase 1 open label, 4 treatment, 4 sequence and 4 period crossover study in subjects with solid tumours no longer responding to, or eligible for standard therapies, and for whom there are no additional standard therapies likely to benefit the subject.

The study is an open-label, randomised, 4-period, 4-sequence crossover pharmacokinetic study designed to generate in vivo PK data from tablet variants with different size/geometry and dose, to correlate with their corresponding in vitro dissolution profiles. The duration of each dosing period is 7 days including the washout period. Subjects will be randomised to a treatment sequence, following a balanced Latin Squares design. Twelve subjects who meet inclusion/exclusion criteria and have provided informed consent will be randomly assigned to the treatment sequences: ABCD, BDAC, CADB, or DCBA.

On Day 1 of each period, subjects will receive a single dose of either Treatment A, B, C, or D, according to the randomisation schedule. Serial blood samples for determination of olaparib in plasma will be collected for up to 72 hours.

Cancer subjects with advanced solid tumours are required for this study, as pre-clinical toxicology data preclude the use of olaparib in healthy volunteers. The olaparib doses chosen will deliver exposure at or below that which has been previously demonstrated to be acceptable and tolerated in cancer subjects.
