Reality: there are at the moment no authorized peanut allergy therapies for youngsters youthful than 4 years previous.
Analysis offered at this yr’s American School of Allergy, Bronchial asthma & Immunology (ACAAI) 2022 annual assembly exhibits that kids 1-3 years previous with peanut allergy who obtained epicutaneous immunotherapy confirmed a statistically important response to remedy.
Epicutaneous immunotherapy (EPIT) exposes tolerance-promoting immune cells within the pores and skin to a dermal patch containing a tiny dose of a meals protein. DBV Applied sciences is pioneering work in EPIT with their Viaskin Peanut remedy.
Throughout a section 3 scientific trial generally known as “EPITOPE”, researchers sought to find out the protection and efficacy of EPIT in kids ages 3 and youthful. Candidate kids have been administered a double-blind, placebo-controlled meals problem (DBPCFC) to find out whether or not they may tolerate a 300mg eliciting dose or much less of peanut protein equal to 1½ peanuts. Those who couldn’t have been randomly assigned to cohorts to obtain both a peanut patch for 12 months of day by day remedy (244 kids) or a placebo patch (118 kids). Security was evaluated based mostly on treatment-emergent antagonistic occasions (TEAEs).
Of the 362 kids (median age: 2.5 years; 68.8% male), 84.8% have been in a position to full remedy. About 67% of youngsters within the lively peanut patch cohort and 33.5% within the placebo patch cohort achieved the first efficacy endpoint of tolerating 300mg of peanut protein. As well as, 64.2% of youngsters who obtained the lively patch and 29.6% who obtained the placebo had a peanut protein eliciting dose of 1000mg or better.
Most TEAEs have been gentle or average reactions confined to the appliance website. Severe TEAEs occurred in 8.6% of youngsters utilizing the peanut patch and in 2.5% utilizing the placebo patch. Among the many kids utilizing the peanut patch, 4 (1.6%) suffered treatment-related anaphylaxis and eight (3.3%) discontinued participation resulting from a TEAE.
The researchers concluded:
Twelve months of epicutaneous immunotherapy with a patch containing 250µg peanut protein was related to a statistically important response vs placebo amongst peanut-allergic kids aged 1-3 years.
