This phase I/II trial studies the safety of acalabrutinib and axicabtagene ciloleucel in treating patients with B-cell lymphoma. Acalabrutinib may stop the growth of tumor cells by blocking key pathways needed for cell growth. Immunotherapy with axicabtagene ciloleucel is engineered to target a specific surface antigen on lymphoma cells. Acalabrutinib may enhance the efficacy of axicabtagene ciloleucel in treating patients with B-cell lymphoma.
