Brief Summary:
The primary hypothesis of the study is single doses of MK-8351 will reduce the baseline early asthmatic response (EAR) as assessed by area under the curve from 0-3 hours (AUC0-3hr) of forced expiratory volume (FEV1) when compared to placebo.

Condition or disease Intervention/treatment Phase
Asthma Drug: Low-Dose MK-8351 Drug: High-Dose MK-8351 Drug: Placebo to MK-8351 Phase 1

Detailed Description:
This is a randomized, placebo-controlled, 4-period study. Eligible patients will undergo a single-blind phase in Period 1, followed by 3 periods during which they will receive low-dose MK-8351, high-dose MK-8351, or matching placebo as a single dose in a random sequence crossover study design.
