研究目的: |
1 主要目的 评估泰它西普在RTX应答不佳的AQP4抗体阳性NMOSD患者中,治疗48周的防复发有效性。 2 次要目的 自身对照疗效: ARR比值(48周治疗期 vs 筛选前RTX治疗期)。 残疾进展控制:评估确认为残疾进展(CDP)的患者比例。。 亚临床评估: 评估MRI新发病灶。 多维功能: 疼痛(NRS)、疲劳(FACIT)、生活质量(EQ-5D-5L/NEI-VFQ-25)。 免疫球蛋白动力学: 比较泰它西普治疗下的IgG下降趋势与既往RTX治疗期的差异(如有历史数据),或与基线对比。 安全性: 评估长期治疗的安全性及耐受性,特别是低丙球血症风险。 3 探索性目的(机制验证) 探索浆细胞、浆母细胞生存因子(IL-6, IL-21, CXCL12, BAFF, APRIL)及外周血B细胞亚群(浆细胞、浆母细胞、记忆B细胞)的动态变化。 炎症指标:C5a,NLR的动态变化。 微结构保护(Advanced MRI): 利用先进MRI技术(DTI),通过测量各向异性分数(FA)和平均扩散率(MD),评估药物对脑和脊髓白质微结构的保护作用;通过监测NfL/GFAP评估神经情况;通过OCT技术评估视神经状况。 |

Objectives of Study: |
1 Primary Objective: To evaluate the efficacy of tetacip in preventing relapse over 48 weeks of treatment in patients with AQP4-antibody-positive NMOSD who had an inadequate response to RTX. 2 Secondary Objectives: Self-controlled efficacy: Ratio of annual relapse rates (ARR) (48-week treatment period vs. pre-screening RTX treatment period). Control of disability progression: To assess the proportion of patients with confirmed disability progression (CDP). Subclinical assessment: Evaluation of new MRI lesions. Multidimensional function: Pain (NRS), fatigue (FACIT), quality of life (EQ-5D-5L/NEI-VFQ-25). Immunoglobulin kinetics: Comparison of the trend in IgG decline under tetacip treatment versus the previous RTX treatment period (if historical data is available), or versus baseline. Safety: Evaluate the safety and tolerability of long-term treatment, particularly the risk of hypogammaglobulinemia. 3. Exploratory Objectives (Mechanism Validation) Investigate dynamic changes in plasma cell and plasma cell precursor survival factors (IL-6, IL-21, CXCL12, BAFF, APRIL) and peripheral blood B-cell subsets (plasma cells, plasma cell precursors, memory B cells). Inflammatory Markers: Dynamic changes in C5a and NLR. Microstructural Protection (Advanced MRI): Utilize advanced MRI techniques (DTI) to assess the drug’s protective effects on the microstructure of cerebral and spinal cord white matter by measuring the fractional anisotropy (FA) and mean diffusion coefficient (MD); evaluate neural status by monitoring NfL/GFAP; and assess optic nerve status using OCT technology. |

排除标准: |
1.诊断为MOGAD、多发性硬化(MS)或其他自身免疫性脑炎。 2.既往使用过靶向BAFF/APRIL通路的生物制剂(如泰它西普、贝利尤单抗)。 3.免疫球蛋白过低: 筛选期IgG < 4.0 g/L。 o 注:若IgG在4.0-5.0 g/L之间且无严重/机会性感染史,经研究者评估获益风险比后可入组,但必须启动二级安全监测(见第11节)。 4.严重的活动性感染: o 乙肝(HBsAg阳性或HBV DNA可检出)、丙肝(HCV RNA阳性)、HIV阳性、梅毒。 o 结核潜伏感染筛查(IGRA)阳性且未完成标准预防性治疗者。 5.妊娠期或哺乳期女性。 6.严重的心、肝、肾功能不全,或近5年内有恶性肿瘤病史。 7.对研究所涉及的试剂过敏。 8.研究者认为不适宜的其他情况。 |
||||||||||||||||||||||
|
Exclusion criteria: |
1.Diagnosed with MOGAD, multiple sclerosis (MS), or other autoimmune encephalitis. 2. Previous use of biologic agents targeting the BAFF/APRIL pathway (such as Telitacicept and belimumab). 3. Hypogammaglobulinemia: Screening period IgG < 4.0 g/L. o Note: If IgG is between 4.0-5.0 g/L and there is no history of severe/opportunistic infections, participants may be enrolled after the investigator assesses the benefit-risk ratio, but secondary safety monitoring must be initiated (see Section 11). 4. Severe active infections: o Hepatitis B (HBsAg positive or detectable HBV DNA), Hepatitis C (HCV RNA positive), HIV positive, Syphilis. o Latent tuberculosis infection screening (IGRA) positive and not completed standard prophylactic treatment. 5. Pregnant or lactating women. 6. Severe cardiac, hepatic, or renal dysfunction, or a history of malignant tumors within the past 5 years. 7. Allergic to reagents involved in the research institute. 8. Other situations deemed unsuitable by researchers. |
