Low Dose Multi-OIT for Food Allergy (LoMo)
Oral immunotherapy (OIT) is a food allergy treatment where small amounts of the food a child is allergic to is eaten and gradually increased over time with the aim to be able to eat a certain amount of the allergen without experiencing an allergic reaction. While this process works in many children there are concerns about safety, feasibility and drop-outs and how to adapt protocols for multiple allergies. Many OIT trials have targeted approximately 4000mg of single food/day. In these trials up to 40% drop-out. There is evidence much lower doses can have beneficial effects. The investigators will evaluate if low doses of foods...
Mepo for EoE Study
Multi-center, randomized, double blind, parallel-arm, placebo controlled trial to determine whether mepolizumab is more effective than placebo for improving symptoms of dysphagia and decreasing esophageal eosinophil counts in adults and adolescents with active eosinophilic esophagitis after an initial 3 month treatment course, and will also assess the impact of an additional 3 months of treatment.
Metronomic Oral Vinorelbine Plus Anti-PD-L1/Anti-CTLA4 ImmunothErapy in Patients With Advanced Solid Tumours
This is a phase I/II national, multicentre, multiple cohort, prospective open-label, non-randomised and non-comparative study, to evaluate the safety and activity of metronomic oral vinorelbine associated with durvalumab + tremelimumab combination immunotherapy for the treatment of advanced solid tumours.
Microbiota and Allergy
Food allergy derives from a dysregulation of oral tolerance mechanisms. Studies suggest a crucial role for gut microbiota in oral tolerance development. An altered composition of gut microbiota results in an unbalanced local and systemic immune response to food allergens. There are qualitative and quantitative differences in gut microbiota composition in children with food allergy. Preliminary results of MATFA study demonstrated gut microbiota in allergic children.These findings support the pivotal role of the gut microbiota in the pathogenesis of allergic diseases and may open new strategies in the development of innovative preventive...
Mixed Nuts and Brain Vascular Function
Impaired brain vascular function precedes the development of reduced cognitive performance, while brain insulin-resistance is also associated with cognitive decline. The Mediterranean diet, which is rich in nuts, may protect against the development of impaired cognitive performance. The hypothesis is that long-term mixed nut consumption increases brain insulin-sensitivity thereby improving brain vascular function and cognitive performance. The primary objective is to evaluate in elderly men and women the effect of 16-week mixed nut consumption on cerebral blood flow, as quantified by the non-invasive gold standard magnetic resonance...
MRI to Assess Fibrosis in Eosinophilic Esophagitis Patients
Can an MRI detect and monitor the inflammatory and fibrotic possess in patients with Eosinophilic Esophagitis
Natural History and Genetics of Food Allergy and Related Conditions
Background: - About 15 million Americans have a food allergy. Because there are no cures or effective prevention or treatment for food allergies, researchers want to learn more about them. Objective: - To learn more about the causes and effects of food allergy and related conditions. Eligibility: - People ages 2 99 who have food allergy and/or a related genetic or other condition - Their relatives - Healthy relatives and volunteers Design: - Participants will have at least 3 visits over 1 2 years, and then once a year for up to 12 years. Each may last a day or longer. ...
Natural History of Eosinophilic Esophagitis
Researchers are trying to understand the course of Eosinophilic Esophagitis (EoE), its progression and effects of treatments.
Omalizumab as Monotherapy and as Adjunct Therapy to Multi-Allergen OIT in Food Allergic Participants
This study is a multi-center, randomized, double-blind, placebo-controlled study in participants 1 to less than 56 years of age who are allergic to peanut and at least two other foods (including milk, egg, wheat, cashew, hazelnut, or walnut). While each participant may be allergic to more than two other foods, the primary endpoint/outcome in this study will only be assessed in peanut and two other foods for each participant. The primary objective of the study is to compare the ability to consume foods without dose-limiting symptoms during a double-blind placebo-controlled food challenge (DBPCFC), after treatment with either ...
Omalizumab to Accelerate a Symptom-driven Multi-food OIT
This study will determine the dose-related efficacy of a 20-week treatment of omalizumab started 8 weeks before the onset of a symptom-driven multi-food oral immunotherapy (OIT) protocol at decreasing time to OIT maintenance dose. Two dosages of omalizumab will be compared to placebo during an oral immunotherapy protocol for three simultaneous food allergens.
