Brief summary

The objective of this study will be to investigate the safety and tolerability of olaparib tablet when given orally to Japanese patients with advanced solid malignancies. In addition, the pharmacokinetic profile, MTD (if possible) and efficacy of olaparib will be investigated.

Inclusion criteria

* Subjects diagnosed with advanced solid malignancies who are refractory to standard therapies or for which no standard therapy exists. * Subjects who have overall good overall general condition. * Subjects who agree to hospitalisation from starting olaparib to multiple dose period at day 15. * Evidence of non-childbearing status for women of childbearing potential, or postmenopausal status. * Subjects who have at least one lesion (measurable and/or non-measurable) that can be accurately assessed by CT/MRI at baseline and follow up visits

Exclusion criteria

* Subjects who received any previous treatment with a PARP (poly adenosine diphosphate-ribose polymerase) inhibitor, including olaparib. * Subjects receiving inhibitors of CYP3A4 (cytochrome P450 3A4). * Subjects with symptomatic uncontrolled brain metastases. * Subjects with myelodysplastic syndrome/acute myeloid leukaemia. * Subjects with a known hypersensitivity to olaparib or any of the excipients of the product.

Number of Participants With Adverse EventsFrom the start dose to 30 days after the last dose of study drugAn adverse event is the development of an undesirable medical condition or the deterioration of a pre-existing medical condition following or during exposure to a pharmaceutical product, whether or not considered causally related to the product. This was recorded if it happend from the start dose to 30 days after the last of study drug.

Number of Participants With Adverse Events

An adverse event is the development of an undesirable medical condition or the deterioration of a pre-existing medical condition following or during exposure to a pharmaceutical product, whether or not considered causally related to the product. This was recorded if it happend from the start dose to 30 days after the last of study drug.

Time frame: From the start dose to 30 days after the last dose of study drug

Number of Participants With Dose Limiting Toxicities

Dose Limiting Toxicities were defined as study specific events that is determined to be possibly or probably related to olaparib (as determined by the investigator) and occurring during the first cycle of treatment (28 days after the first dose), irrespective of whether the toxicity resolved.

Time frame: From the start dose to 28 days after the first dose of study drug

Population: All patients in only the dose escalation part who received olaparib and completed the safety follow-up through the dose-limiting toxicity (DLT) evaluation period (28 days), or who experienced a DLT.
