While the current standard of care for relapsed/refractory large B-cell lymphoma is high-dose therapy with autologous stem cell rescue, many patients do not respond to or cannot tolerate high-dose therapy. As a result, outcomes for second-line treatment remain poor.
At the recent American Society of Hematology (ASH) 63rd Annual Meeting & Exposition in Atlanta, Georgia, Dr. Frederick Locke of Moffitt Cancer Center presented the primary results of ZUMA-7, a phase 3 clinical trial investigating the efficacy of axicabtagene ciloleucel, an autologous anti-CD19 chimeric antigen receptor (CAR) T-cell therapy for patients with relapsed/refractory large B-cell lymphoma. Dr. Locke and his co-investigators found that axicabtagene ciloleucel produced a clinically meaningful, statistically significant improvement in event-free survival compared with the standard of care, along with a manageable safety profile as well. In this interview with Oncology Data Advisor, Dr. Locke discusses the importance of these results and shares advice for members of the cancer care community about how to optimize the use of CAR-T cell therapy for eligible patients with hematologic malignancies.
Oncology Data Advisor: Can you comment on the significance of the results of the ZUMA-7 trial of axicabtagene ciloleucel for patients with relapsed/refractory large B-cell lymphoma?
Frederick Locke, MD: ZUMA-7 is the first randomized, global, multicenter phase 3 clinical trial testing out CAR T-cell therapy against the current second-line standard of care for large B-cell lymphoma. The results we presented have demonstrated that CAR T-cell therapy as a second-line treatment can really provide better efficacy outcomes compared with the current standard of care.
Oncology Data Advisor: What advice could you give to members of the multidisciplinary health care team about making CAR T-cell therapy more accessible for their patients with hematologic malignancies?
Dr. Locke: What's important for community oncologists and other members of the multidisciplinary team to understand is that in order for patients to receive CAR T-cell therapy, they need to be referred as early as possible. In the second-line setting, if a patient is not responding to R-CHOP (rituximab/cyclophosphamide/doxorubicin/vincristine/prednisone) chemotherapy or if they are progressing, the oncologist should immediately be thinking to send that patient to a treatment center that administers axicabtagene ciloleucel. This is the only way to get that patient to CAR T-cell therapy as the very next treatment. Because CAR T-cell therapy works and because it has shown outcomes that are really remarkable, this is what we should be trying to do for our patients.
