This phase II trial tests how well biomarker tests on patients tumor tissue works in selecting personalized treatments for patients with extensive stage small cell lung cancer (ES-SCLC). Biomarker tests look for certain features in cancer cells that may give doctors more information about what is driving cancer and how to treat it. Based on the biomarker test results, study doctors can determine the subtype of ES-SCLC that study treatments can target. This study also tests different types of maintenance treatment for ES-SCLC with drugs durvalumab, saruparib, ceralasertib or monalizumab. Maintenance treatment is given after initial treatment and is given to help keep the cancer under control and prevent it from getting worse. Immunotherapy with monoclonal antibodies, such as durvalumab and monalizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Saruparib is a PARP inhibitor. PARP is a protein that helps repair damaged deoxyribonucleic acid (DNA). Blocking PARP may prevent cancer cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. Ceralasertib may stop the growth of tumor cells and may kill them by blocking some of the enzymes needed for tumor cell growth. Giving biomarker selected personalized maintenance treatment with durvalumab, saruparib, ceralasertib or monalizumab may work better in treating patients with ES-SCLC.
STEP 1: SCREENING AND INDUCTION TREATMENT REGISTRATION: Participants must not have a prior or concurrent malignancy whose natural history or treatment (in the opinion of the treating physician) has the potential to interfere with the safety or efficacy assessment of the investigational regimen
STEP 1: SCREENING AND INDUCTION TREATMENT REGISTRATION: Participants must not have a history of limited stage small cell lung cancer
Treatment naïve and planning to receive frontline induction treatment with platinum plus etoposide in combination with durvalumab, OR,
Have initiated frontline induction therapy and completed at least 1 (≥ 1) cycle and at most 3 (≤ 3) cycles of platinum and etoposide. At most 2 (≤ 2) of these cycles could have been given without durvalumab
