Brief summary
Part I of the study will verify optimal execution of the procedures and acquisition of
satisfactory samples that will be utilized in the main study (Part II); no drug will be
administered. Part II will assess the effect of multiple doses of MK-1029 on the changes in
allergen-induced sputum eosinophils and changes in allergen-induced late asthmatic response
(LAR) when compared to placebo.
