of diffuse large B-cell lymphoma. In April 2022, the FDA approved axicabtagene ciloleucel for adults with large B-cell lymphoma (LBCL) that is refractory to first-line chemoimmunotherapy or relapses within twelve months of first-line chemoimmunotherapy. It is not indicated for the treatment of patients with primary central nervous system lymphoma. Approval was based on ZUMA-7, a randomized, open-label, multicenter trial in adults with primary refractory LBCL or relapse within twelve months following completion of first-line therapy. Participants had not yet received treatment for relapsed or refractory lymphoma and were potential candidates for autologous hematopoietic stem cell transplantation (HSCT). A total of 359 participants were randomized 1:1 to receive a single infusion of axicabtagene ciloleucel following fludarabine and cyclophosphamide lymphodepleting chemotherapy or to receive second-line standard therapy, consisting of two or three cycles of chemoimmunotherapy followed by high-dose therapy and autologous HSCT in participants who attained complete remission or partial remission. In the ZUMA-7 trial, patients treated with axicabtagene ciloleucel had superior clinical outcomes compared with the previous standard of care, including improved overall survival with an estimated 4-year overall survival rate of 54.6% for axicabtagene ciloleucel, compared with 46% for the previous standard of care. In January 2023, the National Institute for Health and Care Excellence (NICE) recommended axicabtagene ciloleucel to treat adult patients with diffuse large B-cell lymphoma (DLBCL) or primary mediastinal large B-cell lymphoma (PMBCL) who have already been treated with two or more systemic therapies.
