Efficacy and Safety of Low-dose Sesame Oral Immunotherapy in Pediatric Patients

Study Purpose

It is a randomized, single-center, controlled trial to evaluate the effectiveness of oral immunotherapy with low-dose sesame protein compared with standard treatment (elimination diet) in patients with sesame allergy.

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	3 Years - 17 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.	NCT06261554
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.	N/A

Additional Details

Allergic reactions to sesame can be severe and life-threatening, making it challenging to avoid hidden sources of the allergen. This pilot study is a randomized controlled trial evaluating the efficacy and safety of oral immunotherapy (OIT) with a low-dose sesame protein in pediatric patients with sesame allergy. The study aims to compare participants undergoing OIT with a maintenance dose of 300mg sesame protein against a control group in a 2:1 randomized allocation. The control group will be recommended a standard treatment, which is a restrictive elimination diet and the use of emergency treatment, including adrenaline, in case of accidental exposure to sesame. 39 participants aged 3-17 with confirmed IgE-mediated sesame allergy will be enrolled into the study. Interventions will be administered once daily for up to 18 months, and the control group will stay under observation for one year. Primary outcomes include the proportion of participants tolerating a single dose of 4000mg sesame protein during the final oral food challenge. Secondary outcomes assess adverse events, changes in immunological parameters, and the maximum tolerated doses of sesame protein in each group.

Arms & Interventions

Arms

Experimental: Sesame immunotherapy

Children with sesame allergy receiving OIT.

No Intervention: Sesame avoidance

Children with sesame allergy not undergoing OIT.

Interventions

Dietary Supplement: - Dietary Supplement: Low dose OIT

Following the building-up phase (up to 14 months), patients will receive a daily low dose of sesame paste (300 mg sesame protein) mixed with well-tolerated fruit mousse or bread for 3 months (12 +/- 3 weeks).
