Inclusion criteria

排除标准:

1.存在活动性感染(临床符合即可); 2.存在DMD 相关心肌病表现,包括: (1)心功能下降的临床症状或体征:如劳累性呼吸困难,足部水肿,平卧位气短,肺底湿啰音等; (2)存在心脏受累的影像学证据:心脏磁共振(cardiac magnetic resonance ,CMR)、经胸超声心动图(transthoracic echocardiography,TTE)测量的左室射血分数(left ventricular ejection fraction,LVEF)<55%;CMR提示严重的心肌纤维化、心功能不全者; 3.呼吸功能不全,需要进行有创或无创通气; 4.年龄别身体质量指数(body mass index-for-age,BMI-for-age)超过第95百分位数; 5.体重超过30公斤; 6.血清学检测提示既往或现症的HIV、乙肝病毒或丙肝病毒感染; 7.既往诊断或正在治疗的自身免疫性疾病; 8.存在显著的实验室指标异常:γ-谷氨酰转移酶(GGT)和/或碱性磷酸酶(ALP)>=3倍正常值上限(upper limit of normal,ULN);总胆红素>=1.5×ULN;肌酐>=159μmol/L;血红蛋白(Hb)<80g/L或>180g/L;白细胞计数>10.0×10^9/L; 9.根据血肌酐值计算的肾小球滤过率(eGFR)<90ml/(min-1.73m^2); 10.血清AAV结合抗体滴度>1:400; 11.存在合并症或需要长期药物治疗的医学情况,研究者认为增加了受试者参与试验的风险; 12.接受试验药物输注前4周以内存在严重感染,例如肺炎、肾盂肾炎或脑膜炎等; 13.筛选前6个月使用过任何研究性药物(GC除外),或外显子跳跃药物(无论是否为研究性); 14.既往接受过任何基因治疗或细胞治疗(例如干细胞移植); 15.研究者认为可能危害受试者安全、影响研究依从性或干扰研究结果解读的其他情况。

Exclusion criteria:

1. Presence of active infection (clinically consistent); 2. Presence of DMD-related cardiomyopathy manifestations, including: (1) Clinical symptoms or signs of cardiac function decline: such as exertional dyspnea, foot edema, orthopnea, basal lung crackles, etc.; (2) Imaging evidence of cardiac involvement: left ventricular ejection fraction (LVEF) measured by cardiac magnetic resonance (CMR) or transthoracic echocardiography (TTE) <55%; CMR indicating severe myocardial fibrosis or cardiac dysfunction; 3. Respiratory dysfunction requiring invasive or non-invasive ventilation; 4. Body mass index-for-age (BMI-for-age) above the 95th percentile; 5. Weight exceeding 30 kg; 6. Serological tests indicating past or current HIV, hepatitis B virus, or hepatitis C virus infection; 7. Previously diagnosed or currently treated autoimmune disease; 8. Presence of significant laboratory abnormality: gamma-glutamyl transferase (GGT) and/or alkaline phosphatase (ALP) >= 3 times the upper limit of normal (ULN); total bilirubin >= 1.5×ULN; creatinine >= 159 μmol/L; hemoglobin (Hb) <80 g/L or >180 g/L; white blood cell count > 10.0 × 10^9/L; 9. Estimated glomerular filtration rate (eGFR) calculated by serum creatinine <90 ml/(min·1.73 m²); 10. Serum AAV binding antibody titer >1:400; 11. Presence of comorbidities or medical conditions requiring long-term medication that the investigator believes increases the risk of trial participation for the subject; 12. Serious infection within 4 weeks prior to study drug infusion, such as pneumonia, pyelonephritis, or meningitis; 13. Use of any investigational drug (except GC) within 6 months prior to screening, or exon-skipping drugs (whether investigational or not); 14. Previous gene therapy or cell therapy (e.g., stem cell transplantation); 15. Other conditions that the investigator believes may endanger the safety of the subject, affect adherence to the study, or interfere with the interpretation of study results.
