Yan Leyfman: Promising results from CD19 CAR-NK Cell therapy trial

Yan Leyfman, Co-founder and executive director of MedNews Week, shared an article by Wen Lei et al, on LinkedIn:

“Promising Results from CD19 CAR-NK Cell Therapy Trial

A Phase 1 trial using CD19-specific CAR-NK cells (CD19-BBz) derived from cord blood showed encouraging safety and efficacy in patients with relapsed/refractory large B cell lymphoma.

Key highlights:
  • Repetitive dosing in 8 patients (NCT05472558)
  • No cytokine release syndrome, neurotoxicity, or GVHD
  • 62.5% overall response rate at day 30
  • 50% achieved complete response
  • Median PFS: 9.5 months; median OS not reached
  • Single-cell RNA-seq revealed response-associated molecular signatures

These results demonstrate the feasibility and safety of CAR-NK therapy, offering a promising alternative to traditional CAR-T in B cell malignancies.”
