Induction of Sustained Unresponsiveness to Sesame Using High- & Low-dose

Status Enrolling by invitation

Clinical Trial Summary

This is an experimental, interventional study, following on from a clinical trial comparing the efficacy and safety of oral immunotherapy with low and high doses of sesame protein, in which patient desensitisation was achieved (High and Low Dose Oral Sesame Immunotherapy - Comparison of Efficacy and Safety, NCT05158413). The aim of this study is to assess a sustained unresponsiveness (SU) to sesame protein after at least 8 months of previously assigned high- or low-dose sesame OIT, followed by 4-week-allergen avoidance, and verified by an open oral food challenge (OOFC).

Clinical Trial Description

Oral immunotherapy is considered the most effective treatment for food allergy. There are two main goals of food immunotherapy: achievement of desensitisation and sustained unresponsiveness. Desensitisation involves achieving temporary tolerance of the allergenic food by the patient only during regular intake of the allergen. The most desirable effect of immunotherapy is to achieve sustained unresponsiveness, i.e. to maintain the absence of adverse symptoms to a given allergen after specific immunotherapy has been discontinued for a defined period of time. The study is a continuation of a clinical trial NCT05158413 which was designed to compare the efficacy and safety of oral immunotherapy (OIT) with low or high doses of sesame protein (300 or 1200 mg, respectively) in children with a confirmed diagnosis of sesame allergy. The participants of current study will be recruited from patients who have accomplished their per-protocol participation in previous trial. Patients will receive the same maintenance dose of sesame allergen, which was used in previous trial (300 or 1200 mg, respectively), for 32 weeks (+/-2 weeks). Then, OIT will be discontinued for 4 weeks with strict sesame avoidance. Subsequently, an open oral food challenge (OOFC) will be performed to assess the achievement of sustained unresponsiveness. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
