| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| To evaluate the dose-related efficacy of MK-8237 sublingual house dust mite (HDM) tablet versus placebo in the treatment of HDM-induced rhinitis based on the average total nasal symptom score (TNSS) determined during the chamber challenge session at Week 24. |
|
| E.2.2 | Secondary objectives of the trial |
Key Secondary Objectives
Evaluate onset of action of MK-8237 versus placebo for HDM-induced rhinitis based on average TNSS during chamber sessions at Week 8, 16, and 24.
Evaluate dose response of MK-8237 versus placebo for HDM-induced rhinitis based on average TNSS during chamber sessions at Week 8, 16, and 24.
Evaluate efficacy of MK-8237 versus placebo for HDM-induced rhinoconjunctivitis based on average symptom score (TSS) [sum of TNSS and TOSS, total ocular symptom score] during chamber session at Week 24.
Other Secondary Objectives
Evaluate efficacy of MK-8237 vs. placebo for HDM-induced rhinoconjunctivitis based on the average DSS (sum of TNSS and TOSS) during chamber sessions at Week 8 and 16.
Evaluate the efficacy of MK-8237 vs placebo for HDM-induced conjunctivitis based on average TOSS during chamber sessions at Week 8, 16, and 24.
Evaluate immunologic parameters during trial period, including HDM specific IgE and IgG4.
