纳入标准:

(1)18周岁≤年龄≤75周岁; (2)患者的重症肌无力日常生活活动能力量表(MG-ADL)评分≥6分,且眼肌评分小于总分50%; (3)足量足疗程使用至少2种常规免疫治疗药物(包括激素及非激素类免疫抑制剂)后,干预后状态(PIS)为无变化或加重;或足量足疗程使用至少2种常规免疫治疗药物后,PIS为改善,但MG-ADL评分仍≥6分且至少持续半年;或足量足疗程使用至少2种常规免疫治疗药物后,PIS为缓解或改善,但在规律减量免疫治疗药物过程中,仍有每年≥2次的疾病症状加重(MG-ADL评分≥6分);或发生危象后经静脉注射免疫球蛋白、血浆置换和大剂量静脉注射甲泼尼龙等多种免疫治疗且积极控制感染后,仍因MG所致呼吸肌无力而无法脱机拔管超过14天; (4)抗AchR或(和)抗Musk或(和)抗LRP4抗体阳性; (5)患者或其法定代理人签署书面知情同意书。

Inclusion criteria

(1) 18 years old <=Age <= 75 years old (2) patients with a Myasthenia Gravis Activities of Daily Living (MG-ADL) scale score of 6 or higher, and an ocular muscle score constituting less than 50% of the total score (3) after receiving an adequate course of at least two conventional immunotherapeutic drugs (including both steroidal and non-steroidal immunosuppressants), the Post-Intervention Status (PIS) remains unchanged or worsens; or after receiving an adequate course of at least two conventional immunotherapeutic drugs, the PIS improves, but the MG-ADL score is still >=6 points and persists for at least half a year; or after receiving an adequate course of at least two conventional immunotherapeutic drugs, the PIS is in remission or improvement, yet during the regular tapering of immunotherapeutic drugs, there are still at least two annual exacerbations of disease symptoms (MG-ADL score >=6 points); or after the occurrence of a crisis, despite multiple immunotherapies such as intravenous immunoglobulin, plasmapheresis, and high-dose intravenous methylprednisolone, and active infection control, the patient still cannot be weaned off the ventilator due to MG-induced respiratory muscle weakness for more than 14 days (4) positive for anti-AChR, and/or anti-MuSK, and/or anti-LRP4 antibodies (5) patient or their legal representative signs an informed consent form in writing

排除标准:

(1)妊娠或哺乳期妇女; (2)对BLINA过敏者; (3)基线前12个月内进行过胸腺切除或者在12周的研究中计划做胸腺切除术者; (4)基线前6个月内接受过靶向CD19或者CD20的生物制剂(CD19或CD20阳性B细胞计数高于正常值下限的受试者可以入组); (5)基线前3个月内使用过依库珠单抗、托珠单抗; (6)基线前4周内接受过静脉注射免疫球蛋白或血浆置换治疗; (7)正在参加其他临床研究。

Exclusion criteria:

(1) pregnant or lactating women (2) individuals with an allergy to Blinatumomab (3) individuals who have undergone thymectomy within the 12 months prior to baseline or who are planning to have a thymectomy during the 12-week study period (4) individuals who have received biologic agents targeting CD19 or CD20 within 6 months prior to baseline are eligible for enrollment (subjects with CD19 or CD20 positive B cell counts above the lower limit of normal are allowed to participate) (5) within the 3 months prior to baseline, use of Ecuzumab and Tocilizumab (6) received intravenous immunoglobulin or plasma exchange therapy within 4 weeks prior to baseline (7) currently participating in other clinical studies
