Exclusion criteria
* Prior systemic therapy for extensive stage or recurrent SCLC * Patients with recurrent SCLC, who received chemotherapy or definitive chest radiation in the past for limited-stage SCLC. * Clinically significant active infection requiring systemic therapy * Pregnant or breastfeeding (NOTE: breast milk cannot be stored for future use while the mother is being treated on study). * Participants who have undergone major surgery within 28 days before first dose of study drug * Participants who are currently receiving any other investigational agents * Active malignancy requiring therapy other than small cell lung cancer, excluding: non-melanoma skin cancer, noninvasive colonic polyps, superficial bladder tumors, cervical cancer in-situ, ductal carcinoma in situ of the breast, monoclonal B-cell lymphocytosis, or monoclonal gammopathy of undetermined significance. * Diagnosis of immunodeficiency or is receiving systemic steroid therapy (\> 10 mg of prednisone or equivalent) or any other form of immunosuppressive therapy within 7 days prior to study enrolment. Patient's on physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment. Topical, inhaled or intra-articular steroids are not considered as systemic steroids. Steroids as premedication for hypersensitivity reaction (e.g. CT scan premedication) or prior to chemotherapy is allowed. * Active autoimmune or inflammatory disorders (including inflammatory bowel disease \[e.g., colitis or Crohn's disease\], systemic lupus erythematosus, or Wegener syndrome \[granulomatosis with polyangiitis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc\]). The following are exceptions to this criterion: * Patients with vitiligo or alopecia * Patients with hyperthyroidism or hypothyroidism (e.g., following Hashimoto syndrome) clinically stable on hormone replacement * Any chronic skin condition that does not require systemic immunosuppressive therapy * Patients with celiac disease controlled by diet alone * Diabetes mellitus with or without insulin replacement therapy * Has history of immune therapy related pneumonitis that required steroids * Patients with untreated or symptomatic central nervous system (CNS) metastases or leptomeningeal carcinomatosis will be excluded. Previously treated CNS metastases and have no requirement for steroids for at least 2 weeks prior to study entry is allowed. Anticonvulsant therapy at a stable dose is permitted and must not have seizures for at least 2 weeks prior to study entry. May have residual symptoms as new baseline. Brain imaging with either MRI (preferred) or CT with contrast must be performed on all subjects at screening to evaluate brain metastases. * Known history of Hepatitis B (known positive HBV surface antigen (HBsAg) result), hepatitis C, or human immunodeficiency virus (positive HIV 1/2 antibodies). Patients positive for hepatitis C (HCV) antibody are eligible only if polymerase chain reaction is negative for HCV RNA * Known history of active tuberculosis * History of allogeneic stem cell or solid organ transplant * History of Ataxia telangiectasia * Uncontrolled intercurrent illness including, but not limited to, serious and active uncontrolled infection, symptomatic congestive heart failure (NYHA class III-IV), active inflammatory bowel disease, unstable angina pectoris, uncontrolled seizures, or psychiatric illness/social situations that would limit compliance with study requirements * Participants with a known hypersensitivity to durvalumab, ceralasertib or any excipient of the product * Patients who have been vaccinated with live, attenuated vaccines within 4 weeks of first dose of study drug * Refractory nausea and vomiting, chronic gastrointestinal diseases or previous significant bowel resection, with clinically significant sequelae that would preclude adequate absorption of ceralasertib. * Patients weighing \<= 30 Kg. * Participants may not be receiving any medications or substances that are potent inhibitors or inducers of CYP3A4 (Appendix B of the protocol). * There is a required wash-out period of 5 half-lives from such agents prior to starting ceralasertib, or three weeks for St. John's Wort. * For non-potent inhibitors or inducers of CYP3A4, the decision to allow a patient to enroll on the study is per investigator best judgement. Note these include common azole antifungals, macrolide antibiotics, and other medications listed in the concomitant medications section. As part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product. * Exposure of other drugs metabolized by CYP3A4 and/or CYP2B6 may be reduced and additional monitoring may be required. * The use of herbal supplements or 'folk remedies' (and medications and foods that significantly modulate CYP3A activity) should be discouraged. If deemed necessary, such products may be administered with caution and the reason for use documented in the CRF.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Progression Free Survival (PFS) | From enrollment until the time of disease progression, assessed for a maximum of 24 months | Progression free survival (PFS) is defined as the time from the initiation of treatment (C1D1) to the time when the criteria for disease progression is met as defined by RECIST v1.1 OR death due to any cause. The PFS is subject to right censoring due to loss to follow-up or at the end of study duration. |
Secondary

|---|---|---|
| Time to disease progression | From enrollment until the time of disease progression,assessed for a maximum of 24 months | Time to disease progression: Will be measured from C1D1 of treatment until the criteria for disease progression is met as defined by RECIST 1.1 |
| Time to CNS Progression | From enrollment until the time of cns progression, assessed for a maximum of 24 months | Time to CNS progression: Will be measured from C1D1 of treatment until the criteria for disease progression is met in the CNS (intracranial) by RECIST 1.1 criteria. Patients with CNS -only progression or those with concurrent CNS and systemic progression will be included in this analysis. |
| Time to Systemic Progression | From enrollment until the time of systemic progression, assessed for a maximum of 24 months | Time to Systemic progression: Will be measured from C1D1 of treatment until the criteria for systemic disease (extracranial) progression is met by RECIST 1.1. Patients with systemic-only or those with concurrent CNS and systemic progression will be included in this analysis. |
| Progression free survival for maintenance therapy | From Cycle 5, Day 1 of maintenance therapy until disease progression, assessed for a maximum of 19 months | Progression free survival for maintenance therapy: Will be measured from C5D1 of first maintenance therapy until the criteria for disease progression is met as defined by RECIST 1.1 |
| Objective response rate (ORR) | 24 months | Objective response rate (ORR): Will include complete response (CR) + partial response (PR) and will be determined as per RECIST1.1 |
| Duration of Response | 24 months | Duration of Response: The period measured from the time that measurement criteria are met for complete or partial response (whichever status is recorded first) until the date that recurrent or progressive disease is objectively documented (taking as reference for progressive disease the smallest measurements recorded since treatment started). |
| Disease Control Rate | 8 weeks from Cycle 1 Day 1 | Disease control rate: The disease control rate is the proportion of all subjects with stable disease (SD) for 8 weeks, or partial response (PR), or complete response (CR) according to RECIST v1.1, from the start of treatment until disease progression/recurrence (taking as reference for progressive disease the smallest measurements recorded since the start of treatment). |
| Overall Survival (OS) | 24 months | Overall survival: Will be measured from D1 to death from any cause |
