Rhinitis, Allergic, Perennial | Efficacy and Safety Study of SCH 900237/MK-8237 in Children and Adults With House Dust Mite-Induced Allergic Rhinitis/Rhinoconjunctivitis (P05607)

Rhinitis, Allergic, Perennial research study

What is the primary objective of this study?

The purpose of this study is to assess the efficacy and safety of MK-8237 (SCH 900237) in the treatment of House Dust Mite (HDM)-Induced Allergic Rhinitis/Rhinoconjunctivitis (AR/ARC) in children and adults. The primary hypothesis of this study is that administration of MK-8237, compared to placebo, results in significant reduction in the average total combined rhinitis score (TCRS).
