Any of the following cardiac criteria:− Mean resting QTc >470 msec obtained from 3 ECGs− Any clinically important abnormalities in rhythm, conduction or morphology of resting ECG eg, complete left bundle branch block, third degree heart block− Any factors that increase the risk of QTc prolongation or risk of arrhythmic events such as heart failure, hypokalaemia, congenital long QT syndrome, family history of long QT syndrome or unexplained sudden death under 40 years of age or any concomitant medication known to prolong the QT interval. 8. Other malignancy within the last 5 years except: adequately treated non-melanoma skin cancer or other solid tumours including lymphomas (without bone marrow involvement) curatively treated with no evidence of disease for ≥5 years. 9. Inadequate bone marrow reserve or organ function as demonstrated by any of the following laboratory values:− Absolute neutrophil count (ANC) <1.5 x 109/L− Platelet count <100 x 109/L− Haemoglobin (Hb) <100 g/L− Aspartate aminotransferase (AST) or alanine aminotransferase (ALT)> 2.5 x upper limit of normal (ULN) if no demonstrable liver metastases or> 5 x ULN in the presence of liver metastases− Total bilirubin >1.5 x ULN if no liver metastases or >3 x ULN in the presence of liver metastases (except in the case of Gilbert’s disease)− Creatinine >1.5 x ULN concurrent with creatinine clearance <50 mL/min (measured or calculated by Cockcroft and Gault equation); confirmation of creatinine clearance is only required when creatinine is >1.5 x ULN− If bone metastases are present and liver function is otherwise considered adequate by the Investigator then elevated alkaline phosphatase (ALP) will not exclude the patient. 10. Refractory nausea and vomiting, chronic gastrointestinal diseases, inability to swallow the formulated product or previous significant bowel resection that would preclude adequate absorption of olaparib or abiraterone. 11. History of hypersensitivity to active or inactive excipients of olaparib or abiraterone or drugs with a similar chemical structure or class to olaparib or abiraterone. 12. Patients with myelodysplastic syndrome/acute myeloid leukaemia. 13. Current disease or condition known to interfere with absorption, distribution, metabolism, or excretion of drugs, at the Investigator’s discretion. 14. Major surgery within 2 weeks of starting study treatment and patients must have recovered from any effects of any major surgery. 15. Judgment by the Investigator that the patient should not participate in the study if the patient is unlikely to comply with study procedures, restrictions and requirements.
    E.5 End points
    E.5.1Primary end point(s)
    Part A To evaluate the safety, tolerability of daily olaparib when given in addition to abiraterone and prednisolone.:-

    The parameters describing the safety and tolerability of olaparib will include: - The percentage of patients with DLTs; -The percentage of patients with adverse events by National Cancer Institute Common Toxicity Criteria for Adverse Events (NCI CTCAE) (version 4.03) grade; - The percentage of patients with serious adverse events; - The percentage of patients who discontinue olaparib due to adverse events or serious adverse events. Adverse events will be assessed by graded Common Terminology Criteria for Adverse Events (CTCAE) v4.0. Clinical chemistry and haematology laboratory tests, and vital signs will also be measured. The number of adverse events that constitute dose limiting toxicities will be derived and used to select a dose to evaluate further in Part B of the study.

    Part B. Radiologic Progression-Free Survival (rPFS).

    rPFS will be assessed from andomization, every 12 weeks, until disease progression or death. Progression-free survival is defined as the time from randomisation until the date of objective disease progression according to RECIST 1.1 (for soft tissue disease) and/or PCWG-2 criteria (for bone
    disease), or death (by any cause in the absence of progression) regardless of whether the patient withdraws from randomised therapy or receives another anti-cancer therapy prior to progression.
    E.5.1.1Timepoint(s) of evaluation of this end point
    Part A - Assessed over 12 months

    Part B - Assessed over 24 months
    E.5.2Secondary end point(s)
    Part A: Olaparib and abiraterone PK parameters: AUCss. Cmax ss, tmax ss, Cmin ss.
    Treatment ratios for abiraterone steady state Cmax and AUC (in combination : alone) and olaparib steady state Cmax and AUC (in combination : alone) will be calculated to assess the
    drug -drug interaction potential between olaparib and abiraterone

    Part B: Overall survival (OS).
    Overall survival is defined as the time from the date of randomisation until death due to any cause.

    Part B: ERG expression/fusion status
    Where possible patient ERG expression/fusion will be assessed and association between this and treatment efficacy will be examined.

    Part B: The time to second progression (PFS2)
    PFS2. Progression defined by local standard clinical practice. May involve any of: objective radiological progression, symptomatic progression, PSA or death.

    Part B: Response to treatment as shown by Overall Response Rates (ORR), changes in PSA
    levels, change in CTC levels over time and measurement of time to requiring further prostate cancer treatment

    Part B: To evaluate the safety, tolerability of daily olaparib when given in addition to abiraterone and prednisolone
    The parameters describing the safety and tolerability of olaparib will include: - The percentage of patients with adverse events by National Cancer Institute Common
    Toxicity Criteria for Adverse Events (NCI CTCAE) (version 4.03) grade; - The percentage of patients with serious adverse events; - The percentage of patients who discontinue
    olaparib due to adverse events or serious adverse events; Assessment of AEs graded by CTCAE v4.0. Clinical chemistry and haematological laboratory tests and vital signs
    also evaluated.
