Official title

Niraparib (PARP Inhibitor) Plus Dostarlimab (Anti-PD1) for Small Cell Lung Cancer (SCLC) and Other High-Grade Neuroendocrine Carcinomas (NEC)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This phase II trial studies the effect of niraparib and dostarlimab in treating small cell lung cancer and other high-grade neuroendocrine carcinomas. Niraparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep cancer cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. Immunotherapy with monoclonal antibodies, such as dostarlimab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving niraparib and dostarlimab may help to control the diseases.
