Lisocabtagene Maraleucel

This phase I/II trial tests the safety, side effects, and best dose/regimen of ST-067 in combination with CD19-directed chimeric antigen receptor (CAR) T-cell therapy (liso-cel) and how well it works in treating patients with large B-cell lymphoma (LBCL) that has come back after a period of improvement (recurrent) or LBCL that has not responded to previous treatment (refractory). ST-067 is an engineered variant of the human cytokine interleukin-18 that may help the immune system kill cancer cells. Lisocabtagene maraleucel (liso-cel) is an autologous CAR T-cell therapy prepared using the person's own immune system (a group of cells, tissues, and organs that protect the body from attack by bacteria, viruses, and cancer cells) to fight the cancer. Giving ST-067 in combination with liso-cel may better treat patients with relapsed/refractory LBCL.

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.
