Abstract: Methods of assessing or monitoring the effect, efficacy, responsiveness to treatment, and/or determining a dose or dosing regimen of therapeutic agents, such as integrin beta7 antagonists, for the treatment of gastrointestinal inflammatory disorders are provided. In certain aspects, methods of using integrin beta7 subunit-containing receptor occupancy by the integrin beta7 antagonist on colonic lymphocytes as an indicator (“biomarker”) of the effect, efficacy, or responsiveness to treatment, and/or as a means to determine dosing or dosing regimens of therapeutic agents such as beta7 integrin antagonists for the treatment of gastrointestinal inflammatory disorders are provided. In certain aspects, methods of assessing the effect, efficacy, or responsiveness to beta7 integrin antagonist treatment by measuring gene expression levels of one or more integrin receptor ligands, lymphocyte genes, cytokine genes, or the number of alphaE-positive cells in intestinal crypt epithelium are provided.

Abstract translation: 提供了评估或监测效果，疗效，对治疗反应性和/或确定治疗剂（例如整联蛋白β7拮抗剂）的剂量或给药方案用于治疗胃肠道炎症性疾病的方法。 在某些方面，使用整联蛋白β7拮抗剂在结肠淋巴细胞上的整合素β7亚基受体占据作为指示剂（“生物标志物”）对治疗的作用，功效或反应性的方法和/或作为测定剂量的方法 或治疗剂如β7整联蛋白拮抗剂的给药方案用于治疗胃肠道炎症性疾病。 在某些方面，通过测量一种或多种整联蛋白受体配体，淋巴细胞基因，细胞因子基因或肠隐窝上皮中αE阳性细胞的数量来评估对β7整联蛋白拮抗剂治疗的作用，功效或反应性的方法 被提供。

Abstract: Methods of treating gastrointestinal inflammatory disorders such as inflammatory bowel diseases including Crohn's disease are provided. Also provided are methods of administering and dosing integrin beta7 antagonists, such as anti-integrin beta7 antibodies. In addition, methods of administrating and dosing such integrin beta7 antagonists to induce remission or to induce and maintain remission of Crohn's disease are provided.
