A Phase III, Randomised, Double Blind, Placebo Controlled, Multicentre Study of Olaparib Maintenance Monotherapy in Patients With Platinum Sensitive Relapsed Ovarian Cancer Who Are in Complete or Partial Response Following Platinum Based Chemotherapy and Whose Tumours Carry Loss of Function Somatic BRCA Mutation(s) or Loss of Function Mutation(s) in Tumour Homologous Recombination Repair -Associated Genes

Olaparib administered as monotherapy in the maintenance setting improves progression free
survival compared to placebo in patients whose tumours carry loss of function (deleterious
or suspected deleterious) somatic BRCA mutations or loss of function (deleterious or
suspected deleterious) mutation in non-BRCA Homologous Recombination Repair (HRR)
-associated genes who have a complete or partial response to platinum-based chemotherapy.

This is a phase III, randomised, double-blind, placebo-controlled, multi-centre study to
assess the efficacy of olaparib maintenance monotherapy in relapsed high grade epithelial
ovarian cancer patients (including patients with primary peritoneal and / or fallopian tube
cancer) who have responded following platinum based chemotherapy. The study population will
be enrolled as two separate cohorts that will enrol simultaneously. The confirmatory cohort
will consist of patients who carry a somatic BRCA mutation (documented mutation in BRCA1 or
BRCA2 that is predicted to be deleterious or suspected deleterious) which are detected in
tumour material but absent from germline blood testing ; the exploratory cohort will include
patients with a mutation (documented mutation predicted to be deleterious or suspected
deleterious) in non BRCA HRR-associated genes which are detected in tumour material
regardless of their germline status.

Inclusion Criteria:

- Patients must be ≥ 18 years of age

- Histologically diagnosed relapsed high grade epithelial ovarian cancer (including
primary peritoneal and/ or fallopian tube cancer)

- Documented deleterious or suspected deleterious somatic BRCA 1 and/or BRCA 2 somatic
mutation or evidence of non- BRCA HRR-associated gene mutation in the tumour.

- At least 2 previous lines of platinum containing therapy prior to randomisation.

- CA-125 measurements prior to randomised treatment

- Patients must have normal organ and bone marrow function measured within 28 days of
randomisation

- Eastern Cooperative Oncology Group (ECOG) performance status 0-1

- Postmenopausal or evidence of non-childbearing status for women of childbearing
potential

- Patient is willing and able to comply with the protocol for the duration of the study
including undergoing treatment and scheduled visits and examinations

- Provision of a blood sample for cfDNA biomarker analysis in Pre-Screening Part 1

- Formalin fixed, paraffin embedded (FFPE) tumour sample from the primary or recurrent
cancer must be available for central testing. If archival tumour sample is not
available tumour sample from fresh biopsy is acceptable, for all patients eligible to
participate in Pre-Screening part 2.

Exclusion Criteria:

- Documented germline mutation in BRCA1 and/or BRCA2 that is predicted to be
deleterious or suspected deleterious (known or predicted to be detrimental/lead to
loss of function).

- Patients who have had drainage of their ascites from the final 2 cycles of their last
chemotherapy regimen prior to randomisation on the study

- Participation in another clinical study with an investigational product during the
chemotherapy course immediately prior to randomisation

- Any previous treatment with a PARP inhibitor, including olaparib

- Patients with a known hypersensitivity to olaparib or any of the excipients of the
product

- Prior malignancy in the last 5 years, unless curatively treated and recurrence free
(few exceptions apply)

- Patients receiving any systemic chemotherapy (including chemotherapy received as the
most recent anticancer therapy) or radiotherapy (except for palliative reasons)
within 3 weeks prior to study randomised treatment

- Persistent toxicities (>Common Terminology Criteria for Adverse Event (CTCAE) CTCAE
grade 2) caused by previous cancer therapy, excluding CTCAE grade 2 peripheral
neuropathy

- Patients with myelodysplastic syndrome/acute myeloid leukaemia (t-AML) or with
features suggestive of MDS/AML

- Patients with symptomatic uncontrolled brain metastases

- Major surgery within 2 weeks of starting study randomised treatment and patients must
have recovered from any effects of any major surgery

- Patients considered a poor medical risk
