简要总结
This phase II trial studies the effect of zanubrutinib and CAR T-cell therapy in treating patients with aggressive B-cell non-Hodgkin's lymphoma or transformed indolent B-cell lymphoma that has come back (recurrent) or does not respond to treatment (refractory). Zanubrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. T cells are infection fighting blood cells that can kill tumor cells. The T cells given in this study will come from the patient and will have a new gene put in them that makes them able to recognize CAR, a protein on the surface of cancer cells. These CAR-specific T cells may help the body's immune system identify and kill cancer cells. Giving zanubrutinib together with CAR T-cell therapy may kill more cancer cells.
详细描述
PRIMARY OBJECTIVE:
I. To determine efficacy of adjunctive zanubrutinib with chimeric antigen receptor T (CAR T)-cell therapy as defined by an improvement in 6-month complete response rates (CR) (defined per 2014 Lugano criteria) as compared to historical rates, in patients treated with CAR T-cell therapy (with a prior lead-in zanubrutinib) followed by maintenance zanubrutinib.
SECONDARY OBJECTIVES:
I. To determine the conversion rates of partial (PR) to complete response (CR), defined per Lugano criteria (2014), in patients with partial response to initial CAR T-cell therapy (with a prior lead-in zanubrutinib) who are administered maintenance zanubrutinib.
II. To determine the overall response rate (ORR), using Lugano criteria (2014), in patients treated with CAR T-cell therapy (with a prior lead-in zanubrutinib) who are administered maintenance zanubrutinib.
