Official title
An Open-Label Phase 1b Dose-Finding Trial Evaluating the Safety of Niraparib and Temozolomide and Atezolizumab in Participants With Advanced Solid Tumors and Expansion to a Phase 2 Trial Comparing the Effects of Niraparib and Temozolomide Plus Atezolizumab vs. Atezolizumab as Maintenance Therapy in Participants With Extensive-Stage Small Cell Lung Cancer With a Complete or Partial Response to Platinum-Based First-Line Chemotherapy (TRIO-US L-06)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This phase Ib/II trial studies the best dose of temozolomide and how well it works with niraparib and atezolizumab in treating patients with solid tumors that have spread to other places in the body (advanced) and extensive-stage small cell lung cancer with a complete or partial response to platinum-based first-line chemotherapy. Drugs used in chemotherapy, such as temozolomide, 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. 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 atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving temozolomide, niraparib and atezolizumab may work better in treating patients with advanced solid tumors and extensive-stage small cell lung cancer.
