Informed Consent * Has (or legally acceptable representative if applicable) provided written informed consent for the study. The participant may also provide consent/assent for future biomedical research. However, the participant may participate in the main trial without participating in the FBR. Exclusion Criteria: * Has a known additional malignancy that is progressing or requires active treatment. Other malignancy unless curatively treated with no evidence of disease for ≥5 years except: adequately treated non-melanoma skin cancer, curatively treated in situ cancer of the cervix, ductal carcinoma in situ (DCIS), Stage 1, grade 1 endometrial carcinoma. * Has myelodysplastic syndrome/acute myeloid leukaemia or features suggestive of MDS/AML. * 3\. Patients with symptomatic uncontrolled brain metastases and/or carcinomatous meningitis. Subject with previously treated brain metastasis may participate proved they are stable (without evidence of progression by imaging for at leat four weeks prior to the first dose of trial treatment and any neurological symptoms have returned to baseline), no evidence of new or enlarging brain metastases. The patient can receive a stable dose of corticosteroids before and during the study as long as these were started at least 4 weeks prior to treatment. Patients with spinal cord compression unless considered to have received definitive treatment for this and evidence of clinically stable disease for 28 days. * 4\. Has a documented weigh loss \> 10% from baseline during screening and/or decline in ECOG PS to \>1 between visit and within 73 hours prior to first dose of therapy. * Has an active infection requiring systemic therapy. * Has a known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial. * Persistent toxicities (\>Common Terminology Criteria for Adverse Event (CTCAE) grade 2) caused by previous cancer therapy, excluding alopecia. Patients previously treated with Oxaliplatinum who experienced a ≤ G2 neuropathy can be included after consultation with the study physician * Patients considered at poor medical risk due to a serious, uncontrolled medical disorder, non-malignant systemic disease or active, uncontrolled infection. Examples include, but are not limited to, uncontrolled ventricular arrhythmia, recent (within 3 months) myocardial infarction, uncontrolled major seizure disorder, unstable spinal cord compression, superior vena cava syndrome, extensive interstitial bilateral lung disease on High Resolution Computed Tomography (HRCT) scan or any psychiatric disorder that prohibits obtaining informed consent. * Is unable to swallow orally administered medication or patients with gastrointestinal disorders likely to interfere with absorption of the study medication. * Is a immunocompromised patients, e.g., patients who are known to be serologically positive for human immunodeficiency virus (HIV). * Has a known active hepatitis (i.e. Hepatitis B or C). * Active hepatitis B virus (HBV) is defined by a known positive HBV surface antigen (HBsAg) result. Patients with a past or resolved HBV infection (defined as the presence of hepatitis B core antibody and absence of HBsAg) are eligible. * Patients positive for hepatitis C virus (HCV) antibody are eligible only if polymerase chain reaction is negative for HCV RNA. Prior/concomitant therapy * Any previous treatment with PARP inhibitor, including Olaparib. * Has prior systemic chemotherapy, targeted small molecule therapy or radiotherapy (except for palliative reasons) within 3 weeks prior to study treatment. * Has received prior therapy with an anti-monoclonal antibody within 4 weeks or who has not recovered (i.e. \<= G1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier. * 15\. Bone as only site of metastatic disease from pancreatic cancer (bone only disease) * 16\. Major surgery within 2 weeks of starting study treatment and patients must have recovered from any effects of any major surgery. * 17\. Is currently receiving known strong CYP3A inhibitors (eg. itraconazole, telithromycin, clarithromycin, protease inhibitors boosted with ritonavir or cobicistat, indinavir, saquinavir, nelfinavir, boceprevir, telaprevir) or moderate CYP3A inhibitors (eg. ciprofloxacin, erythromycin, diltiazem, fluconazole, verapamil). The required washout period prior to starting olaparib is 2 weeks. * 18\. Is currently receiving known strong (eg. phenobarbital, enzalutamide, phenytoin, rifampicin, rifabutin, rifapentine, carbamazepine, nevirapine and St John's Wort) or moderate CYP3A inducers (eg. bosentan, efavirenz, modafinil). The required washout period prior to starting olaparib is 5 weeks for enzalutamide or phenobarbital and 3 weeks for other agents. * 19\. Has received previous allogenic bone marrow transplant or double umbilical cord blood transplantation (dUCBT). * 20\. Has received a whole blood transfusions in the last 120 days prior to entry to the study. Packed red blood cells and platelet transfusions are acceptable, if not performed within 28 days of the first dose of study intervention. Prior/concurrent clinical study experience * 21\. Patients that is currently participating or has participated in another clinical study with an investigational product administered in the last 4 weeks * 22\. Patients with a known hypersensitivity to olaparib or any of the excipients of the product. Diagnostic assessments * 23\. Has resting ECG indicating uncontrolled, potentially reversible cardiac conditions, as judged by the investigator (eg., unstable ischemia, uncontrolled symptomatic arrhythmia, congestive heart failure, QTcF prolongation \>500 ms, electrolyte disturbances, etc.), or patients with congenital long QT syndrome. * 24\. Has a history or current evidence of any condition, therapy or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.
