A Study to Evaluate the Effectiveness of JNJ 40929837 for the Treatment of Asthma Using a Bronchial Allergen Challenge Model
- Registration Number
- NCT01241422
- Brief Summary
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.
- Detailed Description
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.

- Primary Outcome Measures
Name Time Method Change in forced expiratory volume in 1 second (FEV1) during the late response to allergen 3 to 10 hours after allergen exposure on Day 6 of each treatment period
- Secondary Outcome Measures
Name Time Method Area under the FEV1/time curve during the early response to allergen Between 0 and 2 hours post allergen challenge on Day 6 Plasma concentration of JNJ 40929837 Day 1 (predose and 1, 2, 3, and 4 hours), pre-bronchial allergen challenge (BAC) Day 5 (predose and 2 hours), BAC Day 6 (predose and post-BAC [2 and 7 hours]), post-BAC Day 7 (predose and 2 hours), and follow-up visit Change in FEV1 during the early response to allergen 0-2 hours after allergen exposure on Day 6 of each treatment period Area under the FEV1/time curve during the late response to allergen Between 3 and 10 hours post allergen challenge on Day 6 Sputum leukotriene B4 levels Day 1 (predose and 2 and 4 hours), pre-BAC Day 5 (predose), BAC Day 6 (predose, post-BAC [2 and 7 hours]), post-BAC Day 7 (predose), and follow-up visit This biomarker will be measured as a pharmacodynamic evaluation.
Plasma leukotriene B4 levels Day 1 (predose and 2 and 4 hours), pre-BAC Day 5 (predose), BAC Day 6 (predose, post-BAC [2 and 7 hours]), post-BAC Day 7 (predose), and follow-up visit This biomarker will be measured as a pharmacodynamic evaluation.
