Safety and Efficacy of the Addition of Nemtabrutinib to Lisocabtagene Maraleucel in Patients With Relapsed/Refractory Chronic Lymphocytic Leukemia
Fred Hutchinson Cancer Center
Summary
This phase II trial studies how well the addition of nemtabrutinib to lisocabtagene maraleucel in treating patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) that has come back after a period of improvement (relapsed) or that does not respond to treatment (refractory). Nemtabrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Lisocabtagene maraleucel is a type of treatment called chimeric antigen receptor (CAR) T-cell therapy, in which a patient's T-cells (a type of immune system cell) are changed in the laboratory so they will attack cancer cells. T-cells are taken from a patient's blood. Then the gene for a special receptor that binds to a certain protein on the patient's cancer cells is added to the T-cells in the laboratory. The special receptor is called a chimeric antigen receptor (CAR). Large numbers of the CAR T-cells are grown in the laboratory and given to the patient by infusion for treatment. Adding nemtabrutinib to lisocabtagene maraleucel may be an effective treatment for relapsed/refractory CLL/SLL.
Description
OUTLINE: Patients receive nemtabrutinib orally (PO) daily on days 1-28 of each cycle (NOTE: nemtabrutinib is not given during lymphodepleting therapy). Cycles repeat every 28 days for up to 1 year after lisocabtagene maraleucel infusion in the absence of disease progression or unacceptable toxicity. Patients undergo leukapheresis 7 days after start of nemtabrutinib treatment. Patients receive standard of care (SOC) lymphodepleting therapy consisting of cyclophosphamide intravenously (IV) and fludarabine IV on approximately the 5th, 4th, and 3rd day prior to lisocabtagene maraleucel infusion.…
