Efficacy and Safety of Grass Sublingual Tablet in Children and Adolescents (P05239 AM3)(COMPLETED)

Allergy Clinical Trial

Official title:
A Double-Blind, Randomized, Placebo-Controlled, Parallel-Group Study Evaluating the Efficacy and Safety of Sublingual Immunotherapy With SCH 697243 (Phleum Pratense) in Children 5 to <18 Years of Age With a History of Grass Pollen Induced Rhinoconjunctivitis With or Without Asthma

Clinical Trial Summary

The purpose of the study is to investigate the efficacy and safety of a grass sublingual tablet in children and adolescents with a history of grass-pollen induced rhinoconjunctivitis with or without asthma.

Clinical Trial Description

This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in participants aged 5 to <18 years of either sex, and of any race with a history of grass pollen induced rhinoconjunctivitis with or without asthma. While receiving treatment, participants will receive either grass sublingual tablet or placebo. Open-label rescue medications for the rhinoconjunctivitis and asthma symptoms will be provided. Participants will visit the study site for at least 12 visits. A total of 10 allergic symptoms, 6 rhinoconjunctivitis and 4 lung symptoms, will be recorded daily on an electronic diary by the participant/parent/guardian.

The start and end of the grass pollen season (GPS) was determined based on the regional grass pollen count, and lasted up to 162 days. For each region, the GPS is defined as the first day of 3 consecutive recorded days with a grass pollen count of ≥ 10 grains/m^3, to the last day of the last occurrence of 3 consecutive recorded days with a grass pollen count ≥ 10 grains/m^3, inclusively. ;
