Autologous hematopoietic stem cell transplantation followed by CD19/CD22 dual-target CAR-T therapy for refractory or relapsed burkitt lymphoma (ASH 2025) - P=N/A | "The initial ASCTregimen was BEAM until 2022; it was then modified to Be+IDA+FLU+Ara-C+melphalan (BIFAM)...One month post-infusion of CAR-T cells,maintenance therapy with a CD20 monoclonal antibody and chidamide (an histone deacetylaseinhibitors, HDACi) was initiated.There were 9 males and 4 females, with a median age of 29 years (range: 4 to 44)...Subgroup analyses indicated that there were no significantdifferences in 2-year OS and PFS based on the presence of large masses versus their absence (57.1% vs.80%), bone marrow ±CNS involvement (53.3% vs. 71.4%), TP53 abnormalities (71.4% vs. 50%), bridgingtherapy with radiotherapy versus without it (71.4% vs. 53.3%), BEAM versus BIFAM regimens (66.7% vs.66.7%) (all p>0.05).ConclusionThis clinical trial confirmed the efficacy and safety of ASCT followed by CD19/CD22 CAR-T therapy for R/RBurkitt lymphoma, demonstrating a 2-year OS rate of 65.6% and a 2-year PFS rate of 56.3%...There were 9 males and 4 females,..."

Nanobody-based CD19/CD20 bispecific CAR-T achieves durable remissions in r/r NHL patients (ASH 2025) - "Among treatment-refractory cases, 3 had prior CAR-T exposure,including 1 case of CD19/CD22 CAR-T and 2 case of CD19 CAR-T therapy, all with subsequent relapse.Following lymphodepletion, all patients received SL1716 (CD19/CD20 bispecific CAR-T) at 4×106 cells/kg,with 100% manufacturing success rate. SL1716, a nanobody-based CD19/CD20 bispecific CAR-T cell therapy, demonstrates afavorable safety profile and durable clinical efficacy in patients with r/r NHL. These promising resultssupport its potential as an effective treatment option for this high-risk patient population."
