NCT01852825

Brief Summary

The purpose of this study is to assess the effect on various biomarkers of treatment with MK-8237 in participants with allergic rhinitis or rhinoconjunctivitis. In Part 1 of the study healthy participants undergo nasal allergen challenge (NAC) with house dust mite (HDM) extract in order to verify the operational performance of NAC and associated sample collection methods. Part 2, the main study, is a placebo controlled, double blind study of participants with HDM-induced allergic rhinitis or rhinoconjunctivitis. The primary hypotheses are that the changes from baseline in post-allergen challenge HDM-specific Immunoglobulin G4 (IgG4) and Immunoglobulin E blocking factor (IgE-BF) are greater after treatment with MK-8237 than after treatment with placebo.

Outcome Measures

Primary Outcomes (3)

  • Change From Baseline in D. Farinae HDM-specific IgG4 Antibodies in Serum at 12 Weeks (Part 2)

    Blood was collected from participants treated with Dermatophagoides (D.) farinae HDM and then with MK-8237 or placebo, and the amount of HDM-specific IgG4 antibodies in serum at baseline and at week 12 were measured. Fold change from baseline was evaluated based on constrained longitudinal data analysis (cLDA) method with log transformed data. The model included time (categorical variable), treatment, and time by treatment interaction as fixed effects and participants as random effect. Least squares geometric means are presented. It is hypothesized that the change from baseline is statistically greater with MK-8237 treatment than with placebo. This hypothesis is supported if the lower bound of the two-sided 90% confidence interval for the geometric mean fold difference is \>1.0.

    Baseline and 12 weeks

  • Change From Baseline in D. Pteronyssinus HDM-specific IgG4 Antibodies in Serum at 12 Weeks (Part 2)

    Blood was collected from participants treated with D. pteronyssinus HDM, and then with MK-8237 or placebo, and the amount of HDM-specific IgG4 antibodies in serum at baseline and at week 12 were measured. Fold change from baseline was evaluated based on cLDA method with log transformed data. The model included time (categorical variable), treatment, and time by treatment interaction as fixed effects and participants as random effect. Least squares geometric means are presented. It is hypothesized that the change from baseline is statistically greater with MK-8237 treatment than with placebo. This hypothesis is supported if the lower bound of the two-sided 90% confidence interval for the geometric mean fold difference is \>1.0.

    Baseline and 12 weeks

  • Change From Baseline in HDM-specific IgE Blocking Factor (IgE-BF) in Serum at 12 Weeks

    Blood was collected from participants treated with D. pteronyssinus and D.farinae HDM and then with either MK-8237 or placebo, and the amount of IgE-BF in serum was measured based on an Ordinary IgE measurement and an assay in the presence of Competitors; with IgE-BF = 1 - (Competitive IgE/Ordinary IgE). This ranges from 0 (no IgE blocked) to 1 (all IgE blocked); and as it is based on a ratio there are no units. Change from baseline (12 weeks minus baseline) was evaluated based on cLDA method, and was analyzed based on the original scale. The model included time (categorical variable), treatment, and time by treatment interaction as fixed effects and participants as random effect. It is hypothesized that the change from baseline is statistically greater with MK-8237 treatment than with placebo. This hypothesis is supported if the lower bound of the 1-tailed 95% CI around the 12 week mean difference in change from baseline in HDM-specific IgE blocking factor response excludes zero.
