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.

Drug: MK-1029 10 mg
Drug: MK-1029 100 mg
Drug: Placebo for MK-1029 10 mg
Drug: Placebo for MK-1029 100 mg
Phase 1

Primary Outcome Measures:
  • Change from baseline in the percentage of eosinophils in induced sputum [ Time Frame: Baseline (Day -1) and 8 hours after allergen challenge (Day 5) ]
  • Forced expiratory volume at 1 second (FEV1) area under the curve from 3 to 8 hours (AUC[3-8hr]) [ Time Frame: Hour 3 to Hour 8 after allergen challenge (Day 5) ]

Secondary Outcome Measures:
  • Percentage inhibition of eosinophil CD11b expression [ Time Frame: Baseline (Day 1 predose) and 24 hours after dosing on Day 5 ]
