纳入标准:

受试者必须满足以下所有条件才有资格参加此项研究 1. 筛选时年龄 6 月-18 周岁(不含 18 岁),性别不限; 2. 临床确诊 2、3 型 5q SMA; 3. 2 型不具备行走能力,3 型不具备行走能力或具备行走能力不具备独自蹲起能力。 4. 有独坐能力(定义:在有自身上肢支撑情况下独坐 5 秒以上) 5. 单或双手抬到嘴的高度; 6. SMN2 基因修饰突变(c.859 G>C)为阴性; 7. 受试者或其监护人能够理解且愿意遵守研究方案要求和流程,自愿参加并签署知情同意书。

Inclusion criteria

Subjects must meet all of the following criteria to be eligible for inclusion in this study. 1.During the screening process, subjects should be aged between 6 months and 18 years (excluding 18 years old), with no gender restrictions. 2.Clinical diagnosis of Type 2 and Type 3 5q SMA; 3.Type 2 patients lack the ability to walk, while Type 3 patients either lack the ability to walk or possess the ability to walk but are unable to squat and stand up independently. 4.Possessing independent sitting ability (defined as: being able to sit independently for more than 5 seconds with the support of one's own upper limbs) 5.One or both hands can only be raised to the height of the mouth; 6.Negative for SMN2 gene modification mutation (c.859 G>C); 7.The subjects or their guardians are able to understand and are willing to comply with the requirements and procedures of the study protocol, voluntarily participate, and sign the informed consent form.

排除标准:

满足以下任何一项将不能参加此项研究 1. 参加过任何其它基因治疗临床研究; 2. 没有能力参加研究的后期随访; 3. 筛选期前30天内,使用过SMN2靶向调节药物(Spinraza 或Risdiplam) 4. 血清Anti-AAV9中和抗体滴度>1:10(若血清Anti-AAV9中和抗体滴度>1:10,则检测脑脊液Anti-AAV9中和抗体滴度。若脑脊液AntiAAV9中和抗体滴度抗体滴度>1:10,将不能参加此项研究); 5. 易过敏体质患者,包括对泼尼松龙或其他糖皮质激素或其赋形剂过敏或超敏反应、对碘或含碘产品过敏或超敏反应; 6. 存在脊椎穿刺手术或鞘内治疗的禁忌症; 7.

Exclusion criteria:

Individuals meeting any of the following criteria will be ineligible to participate in this study. 1. Having participated in any other gene therapy clinical studies; 2. Unable to participate in the late-stage follow-up of the study. 3. Within 30 days prior to the screening period, the use of SMN2-targeted modulating drugs (Spinraza or Risdiplam) has occurred. 4. Serum anti-AAV9 neutralizing antibody titer >1:10 (if serum anti-AAV9 neutralizing antibody titer >1:10, then cerebrospinal fluid anti-AAV9 neutralizing antibody titer will be measured. If cerebrospinal fluid anti-AAV9 neutralizing antibody titer >1:10, the subject will be ineligible for this study). 5. Patients with a predisposition to allergies, including those with hypersensitivity or allergic reactions to prednisolone or other corticosteroids, or their excipients, as well as those with hypersensitivity or allergic reactions to iodine or iodine-containing products. 6. Contraindications to lumbar puncture or intrathecal therapy are present. 7. X-ray examination reveals severe scoliosis of the spine (≥50°); 8. Planned or anticipated spinal scoliosis correction surgery within 1 year after administration. 9. Invasive ventilation support or blood oxygen saturation <95%; 10. Severe non-respiratory diseases requiring systemic treatment and/or hospitalization within two weeks prior to the initiation of the study. 11. Occurrence of respiratory infections within four weeks prior to the study that require medical care, medical intervention, or any increase in supportive care. 12. Occurrence of severe non-pulmonary/respiratory infections or concomitant diseases within four weeks prior to the administration of the study drug, which, in the opinion of the principal investigator (PI), may pose unnecessary risks to gene transfer, such as significant renal or liver impairment, known epilepsy, diabetes, idiopathic hypocalciuria, or systemic cardiomyopathy. 13. History of bacterial meningitis or brain or spinal cord diseases, including tumors, or magnetic resonance imaging (MRI) or computed tomography (CT) abnormalities that may interfere with lumbar puncture (LP) or cerebrospinal fluid circulation; 14. Unable to discontinue the use of laxatives or diuretics within 24 hours prior to drug administration; 15.
