Outcomes Among Adult Recipients of CAR T-cell Therapy for Burkitt Lymphoma
Menée à partir de données en vie réelle portant sur 31 patients atteints d'un lymphome de Burkitt ayant récidivé ou réfractaire aux traitements, cette étude multicentrique examine les résultats de traitements par lymphocytes CAR-T anti-CD19
Burkitt lymphoma (BL) is an aggressive B-cell lymphoma associated with poor outcomes in patients with relapsed/refractory disease. This multicenter, retrospective study evaluated real-world CD19 CAR T-cell therapy outcomes in patients with relapsed/refractory BL using data abstracted from the medical records. In total, 31 patients received CAR T-cells after a median of 3 prior therapies (range 1-6). Patients received axi-cel (n = 19), liso-cel (n = 4), tisa-cel (n = 4) or other agents (n = 4). Grade 1-2 CRS occurred in 83.9% of patients (grade
≥
3 6.5%), and grade 1-2 ICANS occurred in 29% of patients (grade
≥
3 19.4%). Twenty-eight-day mortality was 16.1%, including one patient who died from grade 5 ICANS. The overall response rate at 1 month was 58.0% with a complete response (CR) rate of 41.9%, however the 6-month CR rate was only 25.8%. Median progression-free survival was 2.3 months (95% CI 1.0 - 9.0), and median overall survival was 6.0 months (95% CI 1.9 - 11.5). Three patients (9.7%) received consolidative allogeneic stem cell transplants, but all subsequently relapsed. In conclusion, CD19 CAR T-cell therapy infrequently delivers long term disease control in BL. Further investigation is needed to determine the most effective alternative management of these patients.
