NCT01644617

Brief Summary

The purpose of this study is to evaluate the dose-related effectiveness, the safety and the tolerability of MK-8237, compared to placebo, in the treatment of house dust mite (HDM)-induced allergic rhinitis/rhinoconjunctivitis in adults. The primary hypothesis is that administration of MK-8237, compared to placebo, results in dose-related improvement in the average total nasal symptom score (TNSS) determined during environmental exposure chamber (EEC) challenge.

Outcome Measures

Primary Outcomes (1)

  • Average Total Nasal Symptom Score (TNSS) During Environmental Exposure Chamber (EEC) Challenge Session at Week 24

    The average total TNSS included the evaluation of 4 nasal symptoms: itchy nose, blocked nose, runny nose, and sneezing. The endpoint was based on participant diary entries over the last 4 hours of the EEC challenge session at Week 24. TNSS was the total of scores for the 4 nasal symptoms, each scored on a 4-point rating scale (0=no symptoms; 1=mild symptoms; 2=moderate symptoms; 3=severe symptoms). The total TNSS ranged from 0 to 12 points. The 24-week TNSS was analyzed using the analysis of covariance (ANCOVA) model with treatment and baseline TNSS as covariates and expressed as a least squares mean with 95% confidence interval. A decrease in TNSS for participants receiving either dose of MK-8237 compared to placebo indicated an improvement in symptoms.
