Rhinitis, Allergic Clinical Trial

Official title:
A Multicenter, Double-Blind, Randomized, Placebo-Controlled, Parallel-Group Study Evaluating the Efficacy and Long-Term Safety of Ragweed (Ambrosia Artemisiifolia) Sublingual Tablet (SCH 39641) in Adult Subjects With a History of Ragweed-Induced Rhinoconjunctivitis With or Without Asthma

Clinical Trial Summary

This study will evaluate the efficacy and safety of ragweed sublingual tablet (SCH 39641/MK-3641/Amb a 1-U) compared with placebo in participants with ragweed-induced rhinoconjunctivitis over a one-year period. It is expected that ragweed allergic participants on one of the active arms of the trial will have decreased allergic rhinoconjunctivitis symptoms and require less allergy rescue medications during ragweed pollen season.
