FARE Clinical Trial Finder
Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||2 Years - 99 Years|
- - GENERAL
INCLUSION CRITERIA:All participants must meet the following criteria: 1.
INCLUSION CRITERIA:The following additional inclusion criteria apply for participants undergoing leukapheresis: 1. Age greater than or equal to 12 years for affected participants; age greater than or equal to 18 years for unaffected relatives and healthy volunteers 2. Stable hematologic paramaters (definition: white blood cell count > 2,500/ L, hemoglobin > 10 g/dL, and platelet count > 75,000/microliter) GENERAL
EXCLUSION CRITERIA:Participants will be excluded for any of the following:
- - Presence of conditions that, in the judgment of the investigator or the referring physician, may put the participant at undue risk or make them unsuitable for participation in the study.
- - Inability to participate for the duration of the study.
- - The PI deems that participation in the study would not be expected to advance the study goals.
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

There are approximately 15 million Americans, including 6 million children, who have a potentially life-threatening food allergy. The prevalence of this disease has increased over the last three decades, in both the United States and other developed countries. There are no cures or effective prevention or treatment strategies for food allergy. Moreover, little is known about the factors that account for the rising prevalence and severity of these diseases in recent years. Both genetic and environmental factors likely contribute to the development of food allergy, but the complex interaction between these variables has frustrated efforts to elucidate pathogenesis and develop mechanism-targeted therapies. Children with food allergy are 2 to 4 times more likely to be diagnosed with asthma or other allergic conditions than children without food allergy, and food allergy may also be an important trigger for atopic dermatitis and eosinophilic esophagitis. The Laboratory of Allergic Diseases within the National Institute of Allergy and Infectious Diseases has a longstanding interest in the genetics and pathogenesis of allergic inflammatory disorders, and with the National Institutes of Health Clinical Center, it provides the ideal environment for the proposed translational studies. In this study, we will:
- (1) investigate the key genetic, cellular, immunologic, and biochemical pathways that lead to the development of food allergy, and (2) identify biomarkers that predict the clinical course and natural history of patients with food allergy.
