2026年11月6日 更新者：AstraZeneca

A Modular, Phase I/II, Open-label, Single-arm, Multicenter, Dose Escalation and Dose Expansion Study to Evaluate the Safety, Tolerability, Cellular Kinetics, Pharmacodynamics, and Efficacy of CT204V-CD19 × CD20, an In Vivo Lentiviral Vector Gene Therapy Generating Dual Targeting Anti-CD19/CD20 Chimeric Antigen Receptor (CAR)-T Cells in Participants With Relapsed or Refractory B-Cell Malignancies

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics and efficacy of CT204V-CD19 × CD20, a dual targeting in vivo gene therapy generating anti-CD19/CD20 CAR-T cells in participants with R/R B-cell malignancies.
