Brief Summary

This study is an investigator-initiated single center, single arm clinical study with a target population of patients with refractory autoimmune diseases. It is an early exploratory clinical study of the safety, tolerability and initial efficacy of CD19/BCMA CAR-T in the treatment of refractory autoimmune diseases.

Conditions

Autoimmune Diseases

Keywords

CD19/BCMA; CAR-T

Outcome Measures

Primary Outcomes (2)

• Incidence of adverse events(AE) after infusion

  The frequency, severity, and laboratory findings of all adverse events/serious adverse events are included.

  Day 28, Month 2, Month 3, Month 6, Month 12, Month 18, Month 24

• Maximal Tolerated Dose(MTD)

  MTD will be determined based on Dose-Limiting Toxicity(DLTs) observed during the first 28 days of study treatment.

  Up to 28 days after infusion]

Study Arms (1)

CD19/BCMA CAR-T for the treatment of refractory autoimmune diseases

EXPERIMENTAL

Subjects who meet the inclusion criteria will receive intravenous infusion of the CD19/BCMA-targeted CAR-T lentiviral vector drug. Following infusion, CD19/BCMA-targeted CAR-T cells will be generated in vivo.

Drug: CD19/BCMA-targeted CAR-T lentiviral vector drug

Interventions

CD19/BCMA-targeted CAR-T lentiviral vector drug DRUG

The CD19/BCMA-targeted CAR-T lentiviral vector drug is administered intravenously, and autologous CD19/BCMA-targeted CAR-T cells are produced in the patient's body following infusion.
