Brief Summary

This is a single-centre, single-arm and open-label study to investigate the safety and efficacy of anti CD19/CD22 CAR NK cells in patients with relapsed refractory B cell lymphoma.

Conditions

Refractory B-Cell Lymphoma

Outcome Measures

Primary Outcomes (1)

• Occurrence of treatment related adverse events as assessed by CTCAE v4.0

  Defined as \>= Grade 3 signs/symptoms, laboratory toxicities, and clinical events) that are possibly, likely, or definitely related to study treatment.
