中文摘要
项目总结:
据估计,多达30%的食物过敏症(FA)患者会患上多种FA。
口服免疫疗法(OIT)的潜在机制和不同的临床疗效尚未很好地了解。
尤其是在对多种食物过敏的个体中,人们和其他人还不清楚它与其他药物结合的程度有多大。
免疫调节疗法可能会改善优降糖在FFA中的安全性或有效性,或改善优降糖的耐受性。
临床结果。在FFA中,有一个尚未得到满足的新的治疗方法的需求,特别是因为它与难治性疾病或疾病有关。
未能治疗这些人群,很可能是由于缺乏大量的细胞因子和分子因子内型,以及更多的临床因子表型。
因为白介素4和白介素13这两种重要的细胞因子是免疫球蛋白的重要推动者,它们在免疫球蛋白的生成中起上游作用。
为了更好地应对这些挑战,我们的新方法是进行一项新的试点,即第二阶段,包括多种新型食品。
过敏原-白介素A(MOIT)的研究旨在比较白蛋白与白介素A联合治疗的安全性、有效性和耐用性。
4Rα单抗与单抗、单抗、单抗、多抗与单抗联合使用。
奥马珠单抗(Omo)。我们假设这样的联合治疗方案可以进一步提高安全性、有效性和/或安全性。
我们还假设,只有DMO,而不是OMO,才会有持续的改善。
对结果的无反应与单独使用相比,这是由于杜匹单抗对白介素4和白介素13的主要作用机制的影响。
我们的研究中心还将在筛查时提供新的样本,包括在整个过程中,以及在新的研究结束后的长期监测中,为在中国进行的关键的生物分析提供样本。
项目有2个细胞(B细胞)、3个细胞(T细胞)和4个细胞(嗜碱性细胞)。因此,我们的研究为我们提供了一个可以说是一个独特的研究机会。
实现我们的总体目标:创建一个全面的全球临床监测和免疫监测数据集体系。
Ooit方案的成果将有助于更好地了解FFA的机制,并有助于进一步提高FFA的安全性和有效性。
FA治疗。我们的具体治疗目标是:1)测试治疗是否需要使用莫莫特或联合使用奥马珠单抗。
或者DUPILUMA单抗与莫特单抗相比,结果显示,有更高比例的参与者能够成功通过一项食品安全挑战。
在一周24小时(主要治疗终点),在经历了一段时间的过敏原停药后,每周24小时(主要治疗终点);;。
2)确定这些治疗方案是否会对这些治疗方案的疗效和安全性产生持久的影响。
并根据受试者的免疫系统反应的变化,证明他们是由这些治疗方法诱导的;;和(3)获得GI。
参与者的活组织检查允许对他们的免疫干细胞进行更详细的生物分析,并在他们的GI组织中发现他们的主要产品,特别是在入境时。
进入第一个试验阶段,以便在疾病控制网站上确定与FFA检查相关的特征,并在整个检查过程中进行检查和评估。
这些功能的选择和方式可能不会改变。第一个项目将不会成为第一个对其进行评估和比较的研究项目。
免疫调节药物联合治疗与单独治疗比较:这项研究和设计的最大新颖性在于与治疗相结合。
对血液样本和胃肠道活检组织的详细机械性研究将使我们能够进一步推进对机械性的理解。
在足协和足协的共同努力下,我们需要建立更有效的治疗方法和更安全的治疗方法。
英文摘要
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.
