SENL101 expanded robustly but persisted shortly, which on the other hand, contributed to the recovery of CD7 + T and NK cells, thereby reducing the risk of infection. An expanded cohort is warranted to verify the long-term benefit of SENL101 for T-cell malignant patients.

Prior to the CAR-T cells infusion, patients received systemic bridging chemotherapy due to rapid disease progression and then all patients received intravenous fludarabine (30mg/m 2 /d) and cyclophosphamide (300mg/m 2 /d) (FC) lymphodepleting chemotherapy for 3 consecutive days (Day -5 to Day -3)...Conclusion This study demonstrated that CD7-targeted CAR-T therapy offers an opportunity to achieve CR for CD7-positive MPAL patients even for those who relapsed post-transplant. Safety was manageable, however, more data on additional patients and longer observation times are needed to further evaluate the efficacy of CD7 CAR-T products.
Importantly, our data indicate that autologous PBMCs from patients were superior to PBMCs of healthy donors in yielding sufficient NS7CAR T cells for therapeutic needs. An investigator-initiated trial is currently ongoing to test the feasibility, efficacy, and safety of NS7CAR T cells for treating T-cell acute lymphoblastic leukemia.

Intravenous fludarabine (30 mg/m 2 /d) and cyclophosphamide (300 mg/m 2 /d) were given to all patients on Day -5 to Day -3 prior to CD7CAR infusion...However, patients with bulky mediastinal masses may require more than one-month time to achieve remission. Long-term observation and more patients are needed to further evaluate the safety and efficacy of CD7CAR.

All patients received intravenous fludarabine (30 mg/m 2 /d) and cyclophosphamide (300 mg/m 2 /d) for 3 days prior to CD7CAR infusion...Conclusions Our results demonstrate that CD7CAR therapy is safe and highly effective in treating patients with heavily pretreated R/R T-ALL, including those with extramedullary involvements, a history of prior allo-HSCT or with high-risk subtypes. More patients and a longer observation time are needed to further evaluate the potential beneficial advantages and side effects of CD7CAR therapy for T-ALL patients.
