Title: A Phase II Open-label, Non-comparative, International, Multicentre Study to Assess the Efficacy and Safety of KU 0059436 Given Orally Twice Daily in Patients With Advanced BRCA1 or BRCA2 Associated Ovarian Cancer
Brief Summary: The purpose of the study is to see if the drug KU 0059436 is effective and well tolerated in treating patients with measurable BRCA1- or BRCA2-positive advanced ovarian cancer and for whom no curative therapeutic option exists.


Options:
A: Inclusion Criteria:

* Advanced ovarian cancer with positive BRCA1 or BRCA2 status
* Failed at least one prior chemotherapy
* In investigators opinion, no curative standard therapy exists
* Measurable disease

Exclusion Criteria:

* Brain metastases
* Less than 28 days since last treatment used to treat the disease
* Considered a poor medical risk due to a serious uncontrolled disorder
B: The following eligibility criteria pertain to patients enrolling into PART 2 of the study:

Inclusion:

* Have a histologically confirmed diagnosis of high grade serous or Grade 2 or Grade 3 endometrioid epithelial ovarian, fallopian tube, or primary peritoneal cancer
* Received at least 3 prior chemotherapy regimens. Non-chemotherapy regimens and maintenance therapies administered as single agent treatment will not count as a chemotherapy regimen
* Relapsed/progressive disease as confirmed by CT scan
* Have biopsiable and measurable disease. Note: biopsy is optional for patients known to harbor a deleterious gBRCA mutation
* Have sufficient archival formalin-fixed paraffin-embedded (FFPE) tumor tissue available for planned analyses

Exclusion:

* History of prior cancers except for those that have been curatively treated, with no evidence of cancer currently (provided all chemotherapy was completed \>6 months prior and/or bone marrow transplant \>2 years prior to first dose of rucaparib).
* Prior treatment with any PARP inhibitor
* Symptomatic and/or untreated central nervous system metastases
* Pre-existing duodenal stent and/or any other gastrointestinal disorder or defect that would, in the opinion of the Investigator, interfere with absorption of rucaparib
* Hospitalization for bowel obstruction within 3 months prior to enrollment
C: Inclusion Criteria:

* Capable of providing signed informed consent, which includes compliance with the requirements and restrictions listed in the ICF and in the Clinical Study Protocol (CSP).
* Provision of signed and dated, written ICF prior to any mandatory study specific procedures, sampling, and analyses.

* Able to provide and consent to the collection of a contemporaneous tumor tissue biopsy and blood sample.
* Able to provide a Formalin Fixed Paraffin Embedded archival tumour tissue block from the time of primary tumour diagnosis (taken ideally prior to receiving any systemic treatment, and definitely prior to first PARPi treatment) for prospective Breast cancer susceptibility gene (BRCA) status testing. If tumour blocks are unavailable, tissue sections are acceptable with a minimum requirement of at least 20 unstained sections on uncharged slides without cover slips. Fine needle aspirates are not acceptable.

* Participants must have a life expectancy of ≥16 weeks.
* Participants must be able to swallow tablets whole.
* For inclusion in the optional (deoxyribonucleic acid) genetics research, study participants must fulfil the following criterion:

Provide informed consent for the genetic sampling and analyses. If a participant declines to participate in the genetics research, there will be no penalty or loss of benefit to the participant. A participant who declines genetics research participation will not be excluded from any other aspect of the main study.

* Participant's body weight must be \>30 kg.
* Postmenopausal or evidence of non-childbearing status for women of childbearing potential.
* Women of childbearing potential and their partners, who are sexually active, must agree to the use of 2 highly effective forms of contraception in combination from the signing of the informed consent (Screening Part 1), throughout the period of taking study treatment and for at least 6 months after the last dose of study drug(s).

Exclusion Criteria:

* Participants who have had drainage of their ascites during the final 2 cycles of their last chemotherapy regimen or during the period between completion of chemotherapy and first dose of study treatment.
* Participants with current signs or symptoms of bowel obstruction, including sub-occlusive disease, related to underlying disease.
* History of leptomeningeal carcinomatosis.
* Participants with symptomatic uncontrolled brain metastases.

  1. A scan to confirm the absence of brain metastases is not required.
