CD19-CAR Immunotherapy for Childhood Acute Lymphoblastic Leukemia (ALL)

Phase 1

Terminated

• Conditions: Acute Lymphoblastic Leukemia

• Registration Number: NCT01195480
• Lead Sponsor: University College, London

Brief Summary

The aim of this clinical trial is to evaluate the feasibility, safety and biological effect of adoptive transfer of CD19ζ chimaeric receptor transduced donor-derived EBV-specific cytotoxic T-lymphocytes (EBV-CTL) in patients with high-risk or relapsed B cell precursor ALL after allogeneic Haematopoietic Stem Cell Transplantation (HSCT).
