Personalized Maintenance Treatments Using Biomarker Tests for Extensive Stage Small Cell Lung Cancer with Durvalumab and Other Targeted Drugs in a Phase II Study

What this Trial Is About

Researchers are evaluating biomarker tests on tumor tissue to select personalized maintenance treatments for patients with extensive stage small cell lung cancer ES-SCLC. This phase II trial aims to determine how well these tests identify cancer subtypes and guide targeted therapies. The study also compares different maintenance treatments, including durvalumab, saruparib, ceralasertib, and monalizumab, which may affect tumor growth and immune response. Participants receive induction treatment with a platinum compound, etoposide, and durvalumab every 28 days for 4 to 6 cycles. After possible thoracic radiation, they are assigned to one of three cohorts based on cancer subtype and SLFN11 status. Each cohort is randomized to receive durvalumab alone or combined with another drug saruparib for cohort A, ceralasertib for cohort B, or monalizumab for cohort C. Maintenance cycles repeat every 28 days if disease does not progress or toxicity occurs. During the study, participants undergo imaging tests such as CT, PETCT, or MRI scans, and tissue and blood samples are collected for analysis. Researchers monitor progression-free survival and overall survival, as well as treatment safety and side effects, for up to three years. After completing study treatment, patients are followed for up to three years to assess long-term outcomes and collect specimens for future research.
