研究概览
简要总结
The purpose of this study is to evaluate the allergen-induced late asthmatic response (LAR), as measured by maximal percent fall in forced expiratory volume in 1 second, in participants with stable mild atopic asthma after treatment with JNJ 40929837 as compared to placebo.
详细描述
This is a multicenter (study conducted at multiple sites), randomized (the study medication is assigned by chance), double-blind (neither the physician nor participant will know which of the treatments a participant is receiving, but can access the information in case of an emergency), and crossover (method used to switch participants from one treatment arm to another in a clinical study) study. Approximately 18 participants will participate in the study. The study will consist of screening phase (30 days before the administration of study drug), treatment phase, and follow-up phase (2 weeks after the end of the last treatment period). Participants will be randomly assigned to receive JNJ 40929837, placebo, and montelukast. Each participant will receive all the 3 treatments (7 days per treatment) and each treatment will be separated by 14 days of wash-out period (no treatment). Safety evaluations will include assessments of adverse events, clinical laboratory tests, electrocardiogram, vital signs, and physical examination, which will be evaluated throughout the study. The maximum study duration for a participant will be approximately 51 days.
