Preventing Childhood Asthma Using Prophylactic House Dust Mite Allergen Immunotherapy — PAPA  

Asthma Clinical Trial

Official title:
Preventing Childhood Asthma Using Prophylactic House Dust Mite Allergen Immunotherapy

Clinical Trial Summary

To establish efficacy and safety of HDM sublingual Immunotherapy (HDM-SLIT) by comparing Odactra and placebo, when given sublingually for 3 years to high risk infants aged between 6 to 12 months at enrollment in preventing the development of asthma, assessed 1.5 years after discontinuation of treatment.

Clinical Trial Description

Aim to prevent the development of asthma in children by intervening at a time when the developing system in still amenable to immune modulation, by using the only therapy that has proven ability to change the natural history of allergic diseases and induce clinical remission. We hypothesize that three years of HDM Immunotherapy in high-risk infants will prevent the development of asthma assessed over a period of 1.5 years after discontinuation of treatment and HDM immunotherapy will result in (a) a significant reduction in the number and pathogenic features of HDM-reactive TH2 cells, and (b) an increase in the numbers of HDM-reactive TH and TREG cells expressing the interferon-response signature. The study is a Randomized (1:1), double blinded, placebo controlled, parallel arms, multi-site, Phase II study with a 3 year treatment phase and further 1.5 year follow-up phase. The study duration for each participant is 4.5 years. Overall study duration is 84 months (7 years); which include 9 months preparation and regulatory approvals, 15 months accrual, 36 months treatment and 18 months follow-up observation period. ;
