About this trial

A single arm, open-label pilot study is designed to determine the safety and effectiveness of anti-CD19 CAR NK cell injection (KN5501) in patients with immune nephropathy. 36 patients are planned to be enrolled in the dose-escalation trial. The primary endpoints are DLT and TEAEs. The secondary endpoints are the overall response rates (ORR) and disease control rate (DCR)

Eligibility criteria

Qualifiers

Age: ≥ 18 years old and ≤ 70 years old, male or female;

Positive CD19 expression in peripheral blood B cells as determined by flow cytometry;

Bone marrow hematopoietic function: a. White blood cell count ≥ 3 x 10^9/L b. Neutrophil count ≥ 1 x 10^9/L (no colony-stimulating factor treatment within 2 weeks before examination); c. Hemoglobin ≥60g/L.

Liver function: ALT ≤ 3 x ULN,AST≤3 x ULN, TBIL≤1.5 x ULN(excluding Gilbert syndrome, total bilirubin ≤ 3.0 x ULN)

Disqualifiers

Individuals with known severe allergic reactions, hypersensitivity, contraindication to any medications during the trial (cyclophosphamide, fludarabine, tozumabs), or subjects with a history of severe allergic reactions;
