Is NCT06777979 recruiting? Yes, currently enrolling (Jun 2026). This Phase 1 trial studies multiple treatments including Fludarabine and Cyclophosphamide for acute lymphoblastic leukemia.

Phase 1RecruitingSt. Jude Children's Research HospitalNCT06777979Data as of Jun 2026

Treatment: Fludarabine · Cyclophosphamide · Mesna · CD19-CD22 CAR T cell infusionThis study is a phase I study designed to evaluate the safety of CD19-CD22-CAR T cells. Primary Objective: To determine the safety profile and propose the recommended phase 2 dose (RP2D) of autologous CD19-CD22-CAR T cells in patients ≤ 21 years of age with recurrent/refractory CD19- and/or CD22-positive leukemia. Secondary Objective: To evaluate the anti-leukemic activity of CD19-CD22-CAR T cells.
