Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type 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.	Interventional
Eligible Ages	4 Years - 65 Years
Gender	All

Trial Details

Trial ID: 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.	NCT05440643
Phase 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.	Phase 1

Additional Details

This is a phase I, open-label, dose-escalation, multi-site trial including subjects with peanut allergy confirmed by screening double-blind, placebo-controlled food challenge. The trial is conducted in 2 parts; part 1 will determine the entry dose of the up-dosing regimen (UDR) in adults and adolescents and part 2 will characterize the tolerability of the up-dosing regimen in adults, adolescents and children. Peanut SLIT tablets administered as 9 doses covering a 4000-fold increase in dose will be used in the study. In part 1, subjects will receive a peanut SLIT-tablet with one of five increasing doses once daily for 2 weeks. In part 2, subjects will receive a series of increasing doses of the peanut SLIT-tablet, where each dose is taken once daily for 2 weeks. The entry dose for the up dosing regimen will be determined from part 1. The trial will consist of up to 10 cohorts (part 1 is cohort 1-5; part 2 is cohort 6-10).
