NCT04037566

A Safety Study of Autologous T Cells Engineered to Target CD19 and CRISPR Gene Edited to Eliminate Endogenous HPK1 (XYF19 CAR-T Cells) for Relapsed or Refractory Haematopoietic Malignancies.

Study Summary

This is a first-in-human trial proposed to test CD19-specific CAR-T cells with edited endogenous HPK1 (XYF19 CAR-T cells) in patients with relapsed or refractory CD19+ leukemia or lymphoma. This is an investigational study designed as a single-center, open-label and single-arm clinical trial.
