项目摘要
PROJECT SUMMARY
It is estimated that as many as 30% of people with food allergy (FA) suffer from multiple FAs. The immune
mechanisms underlying different clinical outcomes of oral immunotherapy (OIT) are not well understood,
particularly in multi-food allergic individuals, and it is not clear to what extent combining OIT with other
immunomodulating therapies might improve the safety or efficacy of OIT in FA, or the durability of favorable
clinical outcomes. There is an unmet need for new therapies in FA, since OIT is associated with refractory or
fail-to-treat populations, likely due to a number of cellular and molecular endotypes and clinical phenotypes.
Because the cytokines IL-4 and IL-13 are important immune drivers of FA that act upstream of IgE in generating
an allergic response, to address these challenges, our approach is to conduct a pilot, phase 2, multiple food
allergen OIT (mOIT) study to compare the safety, efficacy and durability of mOIT combined with the anti-IL-
4Rα antibody dupilumab (DmO) vs. mOIT alone, and vs. mOIT combined with the anti-IgE antibody,
omalizumab (OmO). We hypothesize that such combination therapy could improve the safety, efficacy and/or
durability of mOIT in multi-FA patients. We also hypothesize that DmO, but not OmO, will improve sustained
unresponsiveness outcomes vs. mOIT alone, due to the effects of dupilumab on the actions of IL-4 and IL-13.
Our study will provide samples at screening, throughout OIT, and long-term after OIT, for key bioassays in
Projects 2 (B cells), 3 (T cells) and 4 (basophils). Our study thus offers an arguably unique opportunity to
achieve our overall objective: creating a comprehensive dataset of the clinical and immune monitoring
outcomes of OIT protocols to better understand mechanisms of FA and to improve the safety and efficacy of
FA therapy. Our specific aims are to: 1) Test whether treatment with mOIT combined with either omalizumab
or dupilumab vs. mOIT alone results in a higher proportion of participants being able to pass a food challenge
at week 24 (primary endpoint) and after a period of allergen withdrawal at week 30 (a secondary endpoint);;
2) Determine whether these OIT protocols have lasting effects on the efficacy and safety of these treatments,
and on changes in the subjects' immune responses that were induced by such treatments;; and 3) Obtain GI
biopsies of participants to permit a detailed analysis of immune cells and their products in GI tissues, at entry
into the trial to identify features associated with FA at the disease site, and over the course of OIT to evaluate
whether and how these features might change. Project 1 will be the first study to evaluate and compare each
immunomodulating drug combined with mOIT vs. mOIT alone: the novelty of the study design combined with
detailed mechanistic studies of blood and GI biopsies will permit us to advance the mechanistic understanding
of FA and OIT, and to establish more effective and safer approaches to FA treatment.
项目概要
据估计,多达 30% 的食物过敏 (FA) 患者患有多种 FA。
口服免疫疗法(OIT)不同临床结果的机制尚不清楚,
特别是对于多种食物过敏的个体,目前还不清楚 OIT 与其他食物结合使用的程度。
免疫调节疗法可能会提高 FA 中 OIT 的安全性或有效性,或有利的持久性。
由于 OIT 与难治性或难治性相关,因此 FA 对新疗法的需求尚未得到满足。
无法治疗的人群,可能是由于许多细胞和分子内型以及临床表型。
因为细胞因子 IL-4 和 IL-13 是 FA 的重要免疫驱动因子,在 IgE 的上游发挥作用,产生
过敏反应,为了应对这些挑战,我们的方法是进行试点,第二阶段,多种食物
过敏原 OIT (mOIT) 研究比较 mOIT 与抗 IL- 联合的安全性、有效性和持久性
4Rα抗体dupilumab (DmO)与单独的mOIT相比,以及与mOIT与抗IgE抗体组合相比,
奥马珠单抗(OmO)。我们假设这种联合疗法可以提高安全性、有效性和/或
我们还假设 DmO(而不是 OmO)会持续改善多 FA 患者的 mOIT 持久性。
由于 dupilumab 对 IL-4 和 IL-13 作用的影响,与单独使用 mOIT 相比,出现无反应结果。
我们的研究将为筛选、整个 OIT 以及 OIT 后的长期提供样本,用于以下领域的关键生物测定:
因此,我们的研究提供了一个有争议的独特机会,即项目 2(B 细胞)、3(T 细胞)和 4(嗜碱性粒细胞)。
实现我们的总体目标:创建临床和免疫监测的综合数据集
OIT 协议的结果,以更好地理解 FA 机制并提高 FA 的安全性和效率
我们的具体目标是:1) 测试 mOIT 是否与奥马珠单抗联合治疗。
或 dupilumab 与单独使用 mOIT 相比,能够通过食物挑战的参与者比例更高
在第 24 周(主要终点)和在第 30 周停用过敏原一段时间后(次要终点);;
2) 确定这些 OIT 方案是否对这些治疗的效率和安全性产生持久影响,
以及此类治疗引起的受试者免疫反应的变化;以及 3) 获取 GI;
对参与者进行活组织检查,以便在进入时对胃肠道组织中的免疫细胞及其产物进行详细分析
进入试验以确定疾病部位与 FA 相关的特征,并在 OIT 过程中进行评估
这些特征是否以及如何改变,项目 1 将是第一个评估和比较每个特征的研究。
免疫调节药物联合 mOIT 与单独 mOIT:研究设计的新颖性结合
对血液和胃肠道活检进行详细的机械研究将使我们能够加深对机械的理解
FA 和 OIT,并建立更有效、更安全的 FA 治疗方法。
