A Phase 1 Study of Entinostat in Combination With Atezolizumab / Carboplatin / Etoposide in Previously Untreated Extensive-Stage Small Cell Lung Cancer

National Cancer Institute (NCI)·interventional·Posted Nov 17, 2020·Updated Oct 3, 2025

In Brief

A Phase 1 clinical trial evaluating Atezolizumab, Carboplatin, and 2 other interventions for Extensive Stage Lung Small Cell Carcinoma and 2 related conditions. Completed, enrolled 3 participants across 5 sites.

Detailed Summary

This phase I trial seeks to find out the best dose, possible benefits and/or side effects of entinostat in combination with atezolizumab, carboplatin and etoposide for the treatment of previously untreated aggressive lung cancer that has spread (extensive-stage small cell lung cancer). Entinostat and etoposide may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. 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. Carboplatin is a chemotherapy drug that attaches to deoxyribonucleic acid (DNA) and may kill tumor cells. Giving entinostat in combination with atezolizumab, carboplatin and etoposide may work better than atezolizumab, carboplatin and etoposide alone.
