Brief Summary:
This phase I/II trials investigates the side effects of olaparib and durvalumab and how well it works in combination with carboplatin, etoposide, and/or radiation therapy in treating patients with extensive stage-small cell lung cancer (ES-SCLC) who have not received treatment for their disease. PARPs are proteins that help repair DNA mutations. PARP inhibitors, such as olaparib, can keep PARP from working, so tumor cells can't repair themselves, and they may stop growing. Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as carboplatin and etoposide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy sources to kill tumor cells and shrink tumors. Giving olaparib and durvalumab together with carboplatin, etoposide, and/or radiation therapy may help treat patients with ES-SCLC.

Primary Outcome Measures :
  1. Incidence of dose limiting toxicity [ Time Frame: From start of olaparib, at the end of cycle 6 (each cycle is 28 days) ]
    Will be assessed per Common Terminology Criteria for Adverse Events (CTCAE) version (v) 5.0. Toxicity data by type and severity will be summarized in frequency tables.

Secondary Outcome Measures :
  1. Progression-free survival (PFS) [ Time Frame: Time from starting chemo-immunotherapy until disease progression or death from any cause, assessed up to 1 year ]
    Assessed per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. PFS will be compared to the pre-specified parameter obtained from historical data of comparable patients with extensive-stage small cell lung cancer (ES-SCLC) treated with frontline etoposide plus either cisplatin or carboplatin (EP) chemotherapy followed by thoracic radiation. Will be estimated using the Kaplan-Meier method. Comparison of time-to-event endpoints by important subgroups will be made using the log-rank test. Cox regression model will be applied to evaluate the effect of potential covariates on PFS.

  2. Overall survival (OS) [ Time Frame: Time from starting chemo-immunotherapy until death from any cause, assessed up to 1 year ]
    Will be estimated using the Kaplan-Meier method. Comparison of time-to-event endpoints by important subgroups will be made using the log-rank test. Cox regression model will be applied to evaluate the effect of potential covariates on OS.

  3. Overall response rate (ORR) [ Time Frame: Up to 1 year ]
    The patient's best overall response assignment will depend on the findings of both target and non-target disease and will also take into consideration the appearance of new lesions.

  4. Intra- and extra-thoracic recurrence rates [ Time Frame: Up to 1 year ]
