Treatment groups
Trial outcomes
Primary outcomes
Safe dose of PRG-2311 infusion
To evaluate the safe dose of PRG-2311 infusion, 3 dosage group were designed in this trial, they are 35×10\^6 CAR-T, 100×10\^6 CAR-T, and 300×10\^6 CAR-T
Occurrence of AE after PRG-2311 infusion
To evaluate the occurrence of AE after PRG-2311 infusion based on CTCAE v5.0
Secondary outcomes
LN: Changes of SLE disease activity Index (SLEDAI-2000) score
SLEDAI-2000 is the most commonly used SLE assessment scale. A total of 24 items, the total score is 105 points, scores ≤6 points indicates mild activity, ≥7 but ≤12 is classified as moderate activity, \>12 is classified as severe activity.
LN: Changes of FACIT score
FACIT score is used to assess the fatigue status of patient
LN: Changes of PGA score
PGA score is used to assess the disease activity status of patient by physician
LN: Changes of UPCR
UCPR: urinary protein creatinine ratio (ug/mg)
