About this trial

A Clinical Study on the Safety and Effectiveness of BCMA Chimeric Antigen Receptor T Cells in the Treatment of Refractory Lupus Nephritis and IgG4-Related Disease.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Absolute lymphocyte count: ≥ 0.5 × 10 ^ 9/L [The use of granulocyte colony-stimulating factor (G CSF) is allowed, but subjects are not allowed to receive this supportive treatment within 7 days before the screening period laboratory examination];

Absolute neutrophil count: ≥ 1.0 × 10 ^ 9/L [The use of granulocyte colony-stimulating factor (G-CSF) is allowed, but subjects are not allowed to receive this supportive treatment within 7 days before the screening period laboratory examination];

Platelets: Subject platelet count ≥ 50 × 10 ^ 9/L (subjects are not allowed to receive blood transfusion support within 7 days before the screening period laboratory examination);

Hemoglobin: ≥ 8.0 g/dL (allowing the use of recombinant human erythropoietin) [subjects have not received red blood cell (RBC) infusion within 7 days prior to the screening period laboratory examination];

Disqualifiers

Pregnant or lactating women;

A history of malignant tumors within 5 years (① subjects with cervical carcinoma in situ who have been completely removed and have not experienced recurrence or metastasis for at least 3 years may participate in this study. ② subjects with basal cell or squamous cell carcinoma who have been completely removed and have not experienced recurrence for at least 3 years may participate in this study);(①Carcinoma in situ of the cervix that has undergone curative treatment for more than 12 months prior to screening, ②Basal cell or squamous cell carcinoma of the skin that has been treated therapeutically, ③ Prostate cancer that has been treated with radical prostatectomy or curative radiation therapy for more than 3 years prior to screening has no known recurrence and is not currently receiving treatment;④have had surgery for thyroid cancer, and have not evidence of active disease);

Received any B-cell depletion biologic therapy (for example, rituximab, ocrelizumab, obinutuzumab, ofatumumab, inebilizumab, etc) in the 6 months prior to CAR-T reinfusion, unless B-cell recovery was demonstrated;

Received immunosuppressant therapy within 3 days prior to CAR-T reinfusion, or systemic corticosteroid therapy (>10 mg/ day of prednisone or equivalent doses of other corticosteroids) within 3 days prior to CAR-T reinfusion;

Primary outcomes

1

Safe dose of PRG-1801 infusion

To evaluate the safe dose of PRG-1801 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

Time frame
Up to 24 months after PRG-1801 infusion
2

Occurrence of AE after PRG-1801 infusion

To evaluate the occurrence of AE after PRG-1801 infusion based on CTCAE v5.0

Time frame
Up to 24 months after PRG-1801 infusion

Secondary outcomes

1

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.

Time frame
Baseline,1st month, 2nd month, 3rd month, 6th month, 9th month, 12th month, 18th month, and 24th month after cell infusion
2

LN: Changes of FACIT score

FACIT score is used to assess the fatigue status of patient

Time frame
Baseline,1st month, 2nd month, 3rd month, 6th month, 9th month, 12th month, 18th month, and 24th month after cell infusion
3

LN: Changes of PGA score

PGA score is used to assess the disease activity status of patient by physician

Time frame
Baseline,1st month, 2nd month, 3rd month, 6th month, 9th month, 12th month, 18th month, and 24th month after cell infusion
4

LN: Changes of UPCR

UCPR: urinary protein creatinine ratio (ug/mg)

Time frame
Baseline,1st month, 2nd month, 3rd month, 6th month, 9th month, 12th month, 18th month, and 24th month after cell infusion
