Brief Summary

A Study of Metabolically Armed CD19 CAR-T Cells Therapy for Patients With Moderate to Severe Active Systemic Lupus Erythematosus

Detailed Description

This is a single arm, open-label study. This study is indicated for moderate to severe active systemic lupus erythematosus. The selections of dose levels and the number of subjects are based on clinical trials of similar foreign products and our earlier disclosed clinical trials .

1. Main research objectives:

To evaluate the safety and efficacy of metabolically armed CD19 CAR-T Cells in the treatment of moderate to severe active SLE.

2. Secondary research objectives:

(1) To evaluate the pharmacokinetic (PK) and pharmacodynamics(PD) characteristics of metabolically armed CD19 CAR-T Cells after infusion and their relationship with the number of B cells.

(2) To evaluate the effects of the concentration of autoimmune antibodies and complement after infusion of metabolically armed CD19 CAR-T Cells.

Conditions

Systemic Lupus Erythematosus

Study Design

• Allocation Method: NA
• Intervention Model: SEQUENTIAL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

Administration of Metabolically Armed CD19 CAR-T cells

Patients undergo leukapheresis. Patients will receive a lymphodepletion chemotherapy with cyclophosphamide and fludarabine before CAR-T cells infusion. A dose of metabolically armed CD19 CAR-T cells will be infused on day 0.

Group Type: EXPERIMENTAL

Metabolically Armed CD19 CAR-T cells

• Organ function：

1. Complete blood count (CBC) test [the following criteria should be met within 24 hours prior to apheresis, and supportive treatment such as transfusion, platelet transfusion, cell growth factor (except recombinant erythropoietin) should be avoided within 7 days prior to detection]

• Lymphocyte count ≥ 0.5×109/L (except for those receiving bridging chemotherapy);
• Platelet count ≥ 25×109/L;
• Hemoglobin ≥ 70.0 g/L

2. Blood Biochemistry:

• Serum creatinine (Scr) ≤ 1.5 x ULN, or
• endogenous creatinine clearance ≥ 40 mL/min (using Cockcroft-Gault formula);
• alanine aminotransferase (ALT) ≤ 2.5 x ULN;
• aspartate aminotransferase (AST) ≤ 2.5 ×ULN;
• Total bilirubin (TBIL) ≤ 2 ×ULN; Subjects with total bilirubin < 3 × ULN and direct bilirubin < 1.5× ULN with Gilbert-.Meulengracht syndrome could be included;
• Serum lipase and amylase ≤ 1.5×ULN;
• Alkaline phosphatase (ALP) ≤ 2.5 ×ULN;
• In case of bone or liver metastasis, AST, ALT and ALP ≤ 5 ×ULN;
