Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol. 3. Written informed consent and any locally required authorization obtained from the patient/legal representative prior to performing any protocol-related procedures, including screening evaluations. 4. Histologically or cytologically documented extensive disease (American Joint Committee on Cancer Stage (7th edition) IV SCLC [T any, N any, M1 a/b]), or T3-4 due to multiple lung nodules that are too extensive or have tumor/nodal volume that is too large to be encompassed in a tolerable radiation plan. Brain metastases; must be asymptomatic or treated and stable off steroids and anti-convulsants for at least 1 month prior to study treatment. Patients with suspected brain metastases at screening should have a CT/MRI of the brain prior to study entry. 5. Provision of an archived tumor tissue block (or at least 15 newly cut unstained slides) where such samples exist. 6. Patients must be considered suitable to receive a platinum based chemotherapy regimen as 1st line treatment for the ED-SCLC. Chemotherapy must contain either cisplatin or carboplatin in combination with etoposide. 7. Life expectancy =16 weeks at Day 1. 8. World Health Organization (WHO)/Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 to 2 at enrollment. PS2 patients are permitted to receive first-line treatment, and PS score should be reassessed after first-line treatment. Then patients who are assessed as PS2 at the completion of chemotherapy+durvalumab will be excluded. 9. Body weight >30 kg. 10. At least 1 lesion, not previously irradiated, that can be accurately measured at baseline as =10 mm in the longest diameter (except lymph nodes which must have a short axis =15 mm) with computed tomography (CT) or magnetic resonance imaging (MRI) and that is suitable for accurate repeated measurements as per RECIST 1.1 guidelines. 11. No prior exposure to immune-mediated therapy including, but not limited to, other PARP inhibitor, anti-PD-1, anti-PD-L1, and anti-programmed cell death ligand 2 (anti-PD-L2) antibodies, excluding therapeutic anticancer vaccines. 12. Adequate organ and marrow function which is measured within 28 days prior to administration of study treatment as defined below: Hemoglobin = 10.0 g/dL with no blood transfusion in the past 28 days Absolute neutrophil count =1.5 × 109/L (use of granulocyte colony-stimulating factor is not permitted at screening). Platelet count =100 × 109/L. Serum bilirubin =1.5 × the upper limit of normal (ULN). This will not apply to patients with confirmed Gilbert's syndrome, who will be allowed in consultation with their physicians. In patients without hepatic metastasis: ALT and AST =2.5 × ULN. In patients with hepatic metastases, ALT and AST =5 × ULN. Measured or calculated creatinine clearance: >60mL/min for patients on cisplatin and >51mL/min for patients on carboplatin, as determined by Cockcroft-Gault (using actual body weight) or based on a 24 hour urine test: Males: Creatinine CL (mL/min) = [Weight (kg) × (140 - Age)] / [72 × Serum creatinine (mg/dL)] Females: Creatinine CL (mL/min) = {[Weight (kg) × (140 - Age)] / [72 × Serum creatinine (mg/dL)]}*0.85 13. Evidence of post-menopausal status or negative urinary or serum pregnancy test for female pre-menopausal patients. Women will be considered post-menopausal if they have been amenorrheic for 12 months without an alternative medical cause. The following age-specific requirements apply: Women <50 years of age would be considered post-menopausal if they have been amenorrhoeic for 12 months or more following cessation of exogenous hormonal treatments and if they have luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution or underwent surgical sterilization (bilateral oophorectomy or hysterectomy). Women =50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses >1 year ago, had chemotherapy-induced menopause with last menses >1 year ago, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy). 14. Male patients must use a condom during treatment and for 3 months after the last dose of olaparib when having sexual intercourse with a pregnant woman or with a woman of childbearing potential. Female partners of male patients should also use a highly effective form of contraception Exclusion Criteria: 1. Previous IP assignment in the present study. 2. Concurrent enrollment in another clinical study, unless it is an observational (non interventional) clinical study or during the follow up period of an interventional study. 3. Participation in another clinical study with an IP during the last 4 weeks. 4. Patients unable to swallow orally administered medication and patients with gastrointestinal disorders likely to interfere with absorption of the study medication. 5. Medical contraindication to etoposide platinum (carboplatin or cisplatin) based chemotherapy. 6. Any history of radiotherapy to the chest prior to systemic therapy or planned consolidation chest radiation therapy. Radiation therapy outside of the chest for palliative care (ie, bone metastasis) is allowed but must be completed before first dose of the study medication. 7. Any concurrent chemotherapy, IP, biologic, or hormonal therapy for cancer treatment. Concurrent use of hormonal therapy for non-cancer related conditions (eg, hormone replacement therapy) is acceptable. 8. Major surgical procedure (as defined by the investigator) within 28 days prior to the first dose of IP. Note: Local surgery of isolated lesions for palliative intent is acceptable. 9. History of allogeneic organ transplantation. 10. Has a paraneoplastic syndrome (PNS) of autoimmune nature, requiring systemic treatment (systemic steroids or immunosuppressive agents) or has a clinical symptomatology suggesting worsening of PNS. 11.

The following are exceptions to this criterion: Patients with vitiligo or alopecia Patients with hypothyroidism (eg, following Hashimoto syndrome) and stable on hormone replacement Any chronic skin condition that does not require systemic therapy Patients without active disease in the last 5 years may be included but only after consultation with the investigator Patients with celiac disease controlled by diet alone 12. Uncontrolled intercurrent illness, including but not limited to, ongoing or active infection, interstitial lung disease, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, serious chronic gastrointestinal conditions associated with diarrhea, or psychiatric illness/social situations that would limit compliance with study requirement, substantially increase risk of incurring AEs or compromise the ability of the patient to give written informed consent. 13.
