A Phase 1 study of HBI0101 BCMA-CART in B-Cell Mediated Autoimmune Rheumatic Diseases. The goal of the study is evaluation of safety and identification of the maximum HBI0101 CART dose that may be administered safely to patients with B-cell mediated autoimmune disease.
Eligibility criteria
Qualifiers
Age: 18~80 years old; for patients aged ≥ 75 years, geriatric assessment and endorsement are required;
lack of response per SLEDAI-2k (<4 points reduction from baseline) or no improvement in BILAG domains, or
disease flare per SLEDAI-2k (≥4 points increase from baseline) or new BILAG A or ≥2 new BILAG B organ scores, or intolerance or discontinuation due to adverse effects.
Progression of skin thickening ≥ 12 over the past 6 months or Modified Rodnan skin score (mRSS) ≥15
Disqualifiers

Abnormal liver function: aspartate transaminase (AST) or alanine transaminase (ALT) or glutamyl transpeptidase (GGT) or alkaline phosphatase (ALP) detection value is greater than 5 times the upper limit of normal (ULN); or total bilirubin test value greater than 3 times the upper limit of normal (ULN); Exceptional: liver function disturbance due to myositis.
Cardiovascular disease: Unstable angina or myocardial infarction or coronary artery bypass graft (CABG) within 6 months prior to leukapheresis/ moderate- severe pulmonary hypertension/ severe arrhythmia (ventricular tachycardia, ventricular fibrillation, high grade ventricular block) in the past 6 months; New York heart function class (NYHA) class III- Level IV or LVEF<45%.
Lung disease: patients with chronic lung disease with any of the following: * Oxygen saturation (SpO2) < 90% on room air * FVC≤45% of predicted or DLCO≤40% of predicted at screening. * Evidence of pulmonary hypertension as defined as estimated RVSP> 50 mmHg.
