    Abstract: The invention relates to methods and products for the identification of a clinically significant immune response in subjects treated with a therapeutic protein. A first aspect of the invention relates to methods and compositions for identifying a clinically significant immune response in patients treated with therapeutic amounts of VLA4 binding antibody (e.g., natalizumab). A second aspect of the invention concerns the chronological details of sample collection for determining the titre of antibodies against the therapeutic protein, e.g. the collection of at least two samples at two different time points. A third aspect of the invention relates to the selection of the critical threshold level, which corresponds to the antibody titre of untreated patients increased by the double of the standard deviation of this control antibody titre.

    Abstract translation: 本发明涉及用治疗性蛋白质治疗的受试者鉴定临床显着免疫应答的方法和产品。 本发明的第一方面涉及用治疗量的VLA4结合抗体(例如那他珠单抗)治疗的患者中鉴定临床显着免疫应答的方法和组合物。 本发明的第二方面涉及用于确定针对治疗性蛋白质的抗体滴度的样品收集的时间顺序细节,例如。 在两个不同的时间点收集至少两个样本。 本发明的第三方面涉及临床阈值水平的选择,其对应于未经治疗的患者的抗体滴度增加了该对照抗体滴度的两倍的标准偏差。
