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.

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.

Peanut allergy is a significant clinical problem. Food immunotherapy provides the latest approach to managing food allergy. Oral immunotherapy is considered as the most effective and safe, according to current research. What is more, this type of therapy is easily available and can be continued at patient's home. Obtaining and maintenance of tolerance to the allergic food is the main goal of this procedure. The study will include children with peanut allergy, confirmed during open oral food challenge (OOFC) with peanut protein. First OOFC will be performed before immunotherapy, second one at the end of procedure. Participants will be randomly assigned to two groups. During the maintenance phase, the first group will receive low dose of peanut protein, which amounts 150mg, the second will get high dose, which is 300 mg of peanut protein. Oral immunotherapy with low and high dose of peanut protein in children randomly assigned to two groups (1:1). In the following phase, every two weeks the dose of ground roasted peanut will be increased and applied to a child during hospitalization (1-day procedure). Precondition to increase of dose is good tolerance of previous portion of peanut. The maximum time frame for this phase is 14 months. After achieving tolerance, immunotherapy will be continued for 2 months in maintenance phase, with dose 150mg or 300 mg peanut protein, depending on a study group. The dosage increasing phase will last maximally 14 months. If patients achieves the maintenance dose earlier, this period may be shorter. Maintenance dose is determined by random patients' assignment to one from study's group and amounts 150mg or 300 mg of peanut protein, respectively. The duration of the maintenance phase is 8 weeks (+/-2 weeks). After 2 months (8 weeks +/-2 weeks) of maintenance dose the final OOFC and evaluation of tolerance of peanut protein will be performed. Confirmation of the total desensitization of peanut is the tolerance of a single dose of 4500 mg peanut protein.
