Safety and efficacy of IL-6 knockdown anti-CD19 CAR-T cells (ssCART-19) in the treatment of primary/secondary central nervous system lymphoma (ASH 2025) - P1 | "2 patients received tocilizumab, and 3 receivedsteroids treatment...Of particularsignificance, this patient had previously developed life-threatening grade 4 ICANS with blinatumomabtreatment, manifesting as sudden unconsciousness and coma. Strikingly, after receiving ssCART-19therapy, the case only experienced grade 2 CRS without any ICANS occurrence, demonstrating thefavorable safety profile of ssCART-19 even in CNS lymphoma patients with prior severe ICANS history.The median Tmax was 10 days (range: 7-14), median Cmax was 71,300 copies/μg DNA (range: 1,870-532,000), and median AUC0-28 was 346,391 (range: 18,091-1,750,222).ConclusionssCART-19 demonstrated excellent safety and high response rates in CNSL patients, offering a promisingnew treatment option for primary/secondary CNS lymphoma. Additionally, radiotherapy may serve as aneffective bridging strategy for CNS lymphoma."

A novel loop-structured CD19/CD22 dual-targeting CAR-T therapy for patients with refractory/relapsed B-cell non-Hodgkin lymphoma (ASH 2025) - P1 | "3 patients (17%) had undergone autologous transplantation, and1 (6%) had prior CD19 CAR-T treatment failure...Notably, the 3non-responders still demonstrated robust CAR-T expansion, with a median Cmax of 210,000 copies/μgDNA (range: 2,780-370,000) and median AUC0-28 of 1,841,080 (range: 32,191-2,965,788). This observationsuggests that adequate CAR-T expansion does not necessarily correlate with clinical response,highlighting potential mechanisms of resistance independent of pharmacokinetic factors.ConclusionThe novel loop-structured CD19/CD22 dual-targeting CAR-T cells demonstrate favorable safety andefficacy, offering a promising therapeutic option for refractory/relapsed B-cell non-Hodgkin lymphoma.Larger cohorts and longer follow-up are warranted to validate these findings and assess long-termoutcomes."

Glofitamab use may significantly reduce the efficacy of CAR-T therapy in R/R DLBCL patients (ASH 2025) - P1 | "None of the exposed grouppatients had undergone ASCT or CAR-T therapy previously, whereas in the unexposed group, 2 (20%) hadreceived ASCT and 3 (30%) had prior CD19 CAR-T therapy. Pre-leukapheresis glofitamab usemay impair T-cell function by increasing Treg and PD-1+ T-cell proportions, leading to diminished CAR-Tefficacy (50% lower ORR). We recommend extending the glofitamab washout period and conductingmulticenter clinical studies to further clarify the impact of glofitamab on T-cell function and CAR-Tefficacy."

Phase I Open-Label Single-Arm Study of Sscart-19 in Adult Patients with Relapsed/Refractory B-Cell Acute Lymphoblastic Leukemia in China (ASH 2023) - P1 | "Patients received fractionated infusions split over 3 days (10%; 30%; 60%) after lymphodepleting chemotherapy (3 days fludarabine and cyclophosphamide). ssCART-19 CAR-T cell therapy can effectively reduce the incidence of severe CRS and ICANS, especially control the occurrence of ICANS. And ssCART-19 achieved a high rate of remission in adult patients with R/R B-cell ALL. The ORR within 3 months were 83.3%."

Efficacy and Safety of the Second CAR-T Therapy in Patients with Refractory/Relapsed Acute B-Cell Lymphoblastic Leukemia (ASH 2023) - "A total of 5 patients with severe cytokine release syndrome (Grade ≥ 3) were observed, including 2 patients in the single CD19 CAR-T group, 2 patients in the tandem CD19/CD22 CAR-T group, and 1 patient in the sequential CD19 and CD22 CAR-T group. Of the 23 patients who achieved CR, 4 patients bridged to allogeneic hematopoietic stem cell transplantation (allo-HSCT) and 3 patients received decitabine (DAC) consolidation.With the median follow-up of 25.5 months (range, 1.1 to 33.5), the 2-year overall survival, leukemia-free survival (LFS) and cumulative incidence of relapse rates were 23.7%, 30.5% and 69.5%, respectively. Multivariate Cox regression analyses showed that a better LFS related to the absence of high-risk cytogenetics and genetic characteristics, DAC combination with fludarabine and cyclophosphamide lymphodepletion regimen, and bridging allo-HSCT or DAC consolidation. Our study showed that the second infusion of tandem CD19/CD22 CAR-T therapy obtains a..."

Our preliminary study demonstrated that CD22/CD19 CAR-T and Auto-HSCT "Sandwich" strategy as a consolidation strategy showed favorable safety and efficacy in Ph- B-ALL. CD22/CD19 CAR-T resulted in deeper remission before transplantation. The new strategy may benefit patients from LFS and OS."

Our clinical studies demonstrated the safety and high efficacy of ssCART-19 with IL-6 gene silencing in patients with relapsed/refractory B-ALL. These findings support the potential of ssCART-19 as a promising therapeutic approach for this challenging patient population."

Target Antigen-Expressing T Cells Facilitate CAR-T Cell Eradication of Residual CD19+ B Malignant Cells (ASH 2024) - "Underpinned by this hypothesis, we devised an in vitro model to assess target cell dosage and an in vivo mouse model to simulate the clinical situation of minimal residual disease (MRD), which collectively demonstrated that the immune response of anti-CD19 CAR-T cells is reliant on the dosage of the target antigen, with activation occurring only upon reaching a threshold level of target cells...In fact, our recently published phase I/II study has substantiated the therapeutic impact of employing TAET cells in conjunction with CAR-T cells to achieve complete molecular response (CMR)(bloodadvances.2022009072). Furthermore, this combined treatment strategy is highly flexible and scalable, applicable to various targets, target cell types, and effector cell types, to tackle a range of clinical issues."

EFFICACY AND SAFETY OF CAR-T CELL THERAPY IN B-ALL PATIENTS PREVIOUSLY TREATED WITH BLINATUMOMAB (EBMT 2025) - "Since blinatumomab and CD19 chimeric antigen receptor (CAR)-T cell therapy have similar mechanisms of action, whether prior blinatumomab will affect subsequent CD19 CAR-T cell therapy remains unclear. In this study, we discovered that in patients who had previously received blinatumomab treatment, CAR-T cell therapy remained effective, but the efficacy was reduced compared with blinatumomab-naive patients. Based on the safety profile, the incidence of CRS and ICANS was comparable, and no serious AEs were observed. In conclusion, our findings suggested that the subsequent CD19-targeted therapy after blinatumomab could provide therapeutic benefits to patients with R/R B-ALL."
