Testing of Tazemetostat in Combination With Topotecan and Pembrolizumab in Patients With Recurrent Small Cell Lung Cancer (NCT05353439)

Phase I Dose Escalation and Expansion Study of Tazemetostat in Combination With Topotecan and Pembrolizumab in Recurrent Small Cell Lung Cancer

๐Ÿ”ต Active, Not Recruiting Phase1 ๐Ÿ’Š Investigational Drug / Biologic Sponsor: National Cancer Institute (NCI)

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

This phase I trial tests the safety, side effects, and best dose of tazemetostat in combination with topotecan and pembrolizumab in treating patients with small cell lung cancer that has come back after a period of improvement (recurrent). Tazemetostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as topotecan, 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. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving tazemetostat in combination with topotecan and pembrolizumab may shrink or stabilize recurrent small cell lung cancer.
