Study of Oral Deucrictibant Soft Capsule for On-Demand Treatment of Angioedema Attacks in Adolescents and Adults With Hereditary Angioedema
This is a Phase 3, multicenter, randomized, double-blind, placebo-controlled, 2-period, 2-treatment cross-over study to evaluate the efficacy and safety of orally administered deucrictibant compared to placebo for the on-demand treatment of HAE attacks, including non-severe laryngeal attacks, in participants ≥12 to ≤75 years of age with HAE type 1, type 2, or type 3, a proportion of whom are using long-term prophylactic medication for HAE.

Systems Biology of Early Atopy
The goal of this study is to establish a birth cohort that collects prenatal and early life biosamples and environmental samples and rigorously phenotypes young children for food allergy and Atopic Dermatitis (AD) to identify prenatal and early life markers of high risk for food allergy and AD, as well as biological pathways (endotypes) that result in these conditions. Primary Objectives: - To study the role and interrelationships of established and novel clinical, environmental, biological, and genetic prenatal and early-life factors in the development and course of allergic diseases through age 3 years (or 6 years for those who choose to continue...

Targeted Elimination Diet in EoE Patients Following Identification of Trigger Nutrients Using Confocal Laser Endomicroscopy
Using confocal laser endomicroscopy (CLE), gastrointestinal allergic reactions to certain foods in the duodenum will be evaluated on a cellular level. After that, a personalized exclusion diet will be followed based on the CLE results for 6 weeks, sham-controlled, in a cross-over fashion. Gastroscopy with esophageal biopsies will be repeated after each diet.

Testing Docetaxel-Cetuximab or the Addition of an Immunotherapy Drug, Atezolizumab, to the Usual Chemotherapy and Radiation Therapy in High-Risk Head and Neck Cancer
This phase II/III trial studies how well radiation therapy works when given together with cisplatin, docetaxel, cetuximab, and/or atezolizumab after surgery in treating patients with high-risk stage III-IV head and neck cancer the begins in the thin, flat cells (squamous cell). Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Drugs used in chemotherapy, such as cisplatin and docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Cetuximab is a monoclonal antibody that may interfere with the ability...

Testing What Happens When an Immunotherapy Drug (Pembrolizumab) is Given by Itself Compared to the Usual Treatment of Chemotherapy With Radiation After Surgery for Recurrent Head and Neck Squamous Cell Carcinoma
This phase II trial studies the effect of pembrolizumab alone compared to the usual approach (chemotherapy [cisplatin and carboplatin] plus radiation therapy) after surgery in treating patients with head and neck squamous cell carcinoma that has come back (recurrent) or patients with a second head and neck cancer that is not from metastasis (primary). Radiation therapy uses high energy radiation or protons to kill tumor cells and shrink tumors. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of cancer cells. Carboplatin is also in a class of medications known as platinum-containing compounds....

The Esophageal String Test as a Diagnostic Screening Tool for Eosinophilic Esophagitis Among Africans With Dysphagia in Mali and the United States
Background: Eosinophilic esophagitis (EoE) is a disease that causes inflammation in the esophagus. The esophagus is the tube that moves food from the mouth to the stomach. Diagnosing EoE currently requires a specialized tool called an endoscope. The esophageal string test (EST) is another test; the EST collects fluid from the upper digestive tract. An EST is simpler and cheaper than an endoscopy. Researchers want to know if an EST can diagnose EoE. Objective: To test if the EST can diagnose EoE in people who have trouble swallowing. Eligibility: Adults aged 18 to 65 years with trouble swallowing. They must have been born in Africa and be of African...

The NACHO Trial (Nut Allergy Children OIT)
Most food allergies that begin in early childhood are mild and resolve by school age, but nut allergies persist in about 80-90% of individuals into adulthood. The consumption of nuts, particularly cashew nuts, has increased dramatically in Finland in the 21st century, leading to a rise in severe allergic reactions to cashew nuts among young children. Of the food anaphylaxis cases reported in the Finnish Anaphylaxis Registry between 2015-2020, 49% were caused by nuts, with cashew nuts being the most common trigger. The standard treatment for nut allergies is strict avoidance of nuts and symptom management with emergency medications. Oral immunotherapy (OIT) is a food allergy...

The Potential Role of Compounds Derived From Ultra-processed Foods in Pathogenesis of Eosinophilic Esophagitis
Eosinophilic esophagitis (EoE) is a chronic antigen-mediated inflammatory disease of the esophagus that affects both children and adults. The incidence and prevalence of EoE is rapidly increasing in Western countries with an estimated incidence of 6.6 per 100,000 person-years (95% CI, 3-11.7) in children and 7.7 per 100,000 person-years (95% CI, 1.8-17.8) in adults. Clinically, it is characterized by various symptoms related to esophageal dysfunction, including vomiting, regurgitation, feeding difficulties, epigastric heartburn, dysphagia, or food bolus impaction, and may cause growth retardation. Diagnosis is made on the basis of clinical symptoms and histological evidence of...
