What this Trial Is About
Researchers are evaluating the safety and effectiveness of donor-derived CD19 CAR-T cells in treating relapsed or refractory B-cell acute lymphoblastic leukemia (R/R B-ALL). This early-phase clinical study aims to expand the sample size to gather more safety data while further assessing the treatment's effectiveness in patients who have not responded well to standard therapies or have relapsed multiple times. Participants receive CD19-targeted CAR-T cells through intravenous infusion. The treatment focuses on patients whose leukemic B cells express the CD19 marker and who have either failed standard chemotherapy or other treatments, including autologous CAR-T preparation. The study builds on previous safety data and continues to monitor participants closely. During the study, patients undergo various assessments including monitoring for dose-limiting toxicity within 28 days after treatment and tracking treatment-emergent adverse events for up to two years. Researchers evaluate clinical responses, laboratory tests, and heart function. Participants must provide informed consent and agree to use contraception if fertile. The study involves continuous safety monitoring over an extended period to understand both short-term and long-term effects.
