项目摘要
PROJECT SUMMARY
Food allergies (FAs) are a world-wide problem, and allergies to multiple foods are particularly problematic. In
the U.S., ingestion of offending food allergens is the most common cause of anaphylaxis seen in hospital
emergency departments (EDs), and it is estimated that ~30,000 food-induced anaphylactic events are seen in
U.S. EDs each year;? sadly, ~200 of these events prove fatal. Peanuts or tree nuts cause the majority of these
deaths, and a recent survey in the U.S. found that 1.4% of the population is allergic to peanuts or tree nuts and
~30% of patients with FAs have allergies to multiple foods. In peanut allergy (PA), landmark studies by A.
Wesley Burks and colleagues have shown that children can be desensitized to peanut via an oral
immunotherapy (OIT) protocol. We have replicated these results in adults and children, and also have carried
out a pilot study showing that FA patients can be desensitized to multiple food allergens simultaneously (i.e.,
multi-OIT). Moreover, we found that there were fewer adverse events in the build-up phase of multi-OIT if
patients received the anti-IgE antibody, omalizumab, concomitantly with multi-OIT.
In an effort to improve understanding of the systemic and local (i.e., GI) immune responses that underlie PA
and therapeutic responses to OIT, we are currently conducting a placebo-controlled, randomized, phase 2
clinical trial of OIT in 120 children and adults with PA (the POISED trial), and are applying state-of-the-art
human immune monitoring methods to analyze blood and GI tissue specimens of participants in that study. In
this AADCRC U19 renewal application, we propose to conduct a pilot, placebo-controlled, randomized, phase
2 clinical trial of OIT with or without omalizumab or the anti-IL-4Rα antibody, dupilumab, in children and adults
with multiple FAs (multi-FAs). We propose to measure a broad range of blood and GI biopsy cellular findings,
as well as serologic and clinical findings, in longitudinal samples from multi-FA participants undergoing the trial,
as well as from appropriate control participants (i.e., multi-FA participants who are not treated, healthy controls,
and atopic controls without FA). We will use these data to define how key systemic or GI tissue immune
parameters change during multi-OIT, and which are most predictive of the nature and durability of patient
responses to this therapy. Specifically, we will evaluate whether there are blood- or GI tissue-derived
biomarkers that predict therapeutic responses to individual allergens, or to all allergens, in multi-OIT. In
addition, we will seek to identify immune monitoring parameters, including findings derived from analyses of
basophil phenotype and function that can be rapidly performed in a clinical laboratory using small amounts of
blood, that could be used to predict the clinical reactivity to offending allergens in multi-FA subjects, to improve
the safety and efficacy of OIT protocols, and/or to tailor the OIT protocol to each individual subject.
项目总结:
食物过敏(FA)是一个世界性的问题,由多种食物引起的过敏症尤其成问题。
在美国,摄入有害食物和过敏原是医院常见的过敏反应最常见的原因之一。
据估计,急诊科(EDS)、医院和医院大约有3万起由食物引起的过敏性疾病事件。
美国急诊室每年都会发生;可悲的是,这些事件中有大约200%会被证明是致命的。这些事件中的绝大多数是由花生或树坚果引起的。
美国东部最近的一项调查发现,约1.4%的美国人对花生或坚果等食物过敏。
美国食品和药物管理局的一项里程碑式的研究显示,在患有花生过敏的患者中,约有30%的人对多种食物过敏。
韦斯利、伯克斯和他的同事们已经证明,儿童对花生的脱敏可以通过一次口头治疗来实现。
免疫疗法(OIT)是一项协议。我们已经在大多数成人和儿童身上复制了这些结果,儿童和儿童也没有携带这些结果。
英国的一项试点研究表明,可以对患者进行脱敏治疗,以同时检测多种主要食物和过敏原(即)。
此外,我们还发现,在多用途车的建设和阶段阶段,发生的不良反应事件较少。
接受了新的抗IgE抗体的患者,Momalizumab伴随着多项免疫反应。
中国参与了一项旨在进一步提高对全球系统性问题和地方政府(即GI)和免疫系统应对措施的理解的努力,这些措施可能是EPA的基础。
以及对Cooit的治疗反应,我们目前正在进行一项新的安慰剂对照、随机、第二阶段试验。
在120名患有儿童和成人的儿童和成人中进行的临床试验(即将进行的临床试验),他们和他们正在应用这项最先进的技术。
在这项研究中,人类免疫系统监测方法需要对所有参与者的血液和胃肠道组织标本进行分析。
这是AADCRC对U19的续签申请,如果我们建议继续进行试点,不进行安慰剂对照,不进行随机分阶段。
2名儿童和成人使用或不使用抗IL-4Rα单抗的临床和临床试验。
我们将提出一种方法,以测量更广泛范围的血液样本和胃肠道活组织检查以及细胞生物学检查结果。
除了血清学检查和临床检查结果外,还包括来自正在接受临床试验的多名FA参与者的纵向样本。
以及来自未接受适当治疗的参与者(即,多名足协成员)和健康的医疗控制组的建议。
和特应性疾病(在没有FA的情况下进行控制)。我们将继续使用这些数据来定义关键的系统性疾病或GI组织如何免疫。
参数可能会在多个阶段发生变化,其中最具预测性的是患者的自然状态和耐久性。
对这种新疗法的反应是。具体地说,我们将不会评估是否有血液或胃肠道组织来源的疾病。
生物标记物可以预测对个别过敏原的治疗反应,也就是对所有过敏原的治疗反应,尤其是在多个阶段。
此外,我们还将寻求帮助确定免疫系统监测的参数,包括从对病毒的分析中得出的结果。
嗜碱性粒细胞的表型和功能表明,它可以在一家大型临床医学实验室使用少量的细菌进行快速检测。
血液可以被用来预测在多个FA受试者中是否存在令人不快的过敏原的临床反应能力,以便进一步改善。
Ooit协议的安全性和有效性,以及为每个单独的受试者量身定做的Ooit协议的安全性和有效性。
