Overview
Brief Summary
The purpose of this study is to evaluate the safety and effectiveness of once daily oral administration of JNJ-39758979 in the treatment of adults (18 to 65 years of age) with persistent asthma.
Detailed Description
This is a multicenter, double-blind (neither physician nor participants knows the treatment that the participant receives), randomized (study medication is assigned by chance), placebo-controlled (an inactive substance is compared with a medication to test whether the medication has a real effect in a clinical study), parallel group (each group of participants will be treated at the same time), exploratory study (JNJ-39758979 is introduced in participants with asthma for the first time). This study consists of 4 phases: screening phase (4 weeks prior to the start of the run-in period), placebo run-in phase (2 weeks prior to the start of treatment phase), double-blind treatment phase (12 weeks), and posttreatment phase (5 weeks). Approximately 100 participants will be randomly allocated to 1 of 2 treatment groups: Treatment A (participants will receive JNJ-39758979 once daily) and treatment B (participants will receive placebo once daily). Safety will be evaluated by assessment of adverse events, clinical laboratory tests, vital signs, physical examination, and 12-lead electrocardiogram. Total study duration for each participant will be approximately 23 weeks.

Outcomes
Primary Outcomes
Percent change from baseline to Week 12 in pre-bronchodilator percent predicted Forced Expiratory Volume in 1 second (FEV1) value
Time Frame: Baseline (Week 0) and Week 12
FEV1 will be measured by using spirometry test. Spirometry is used to measure lung function, specifically the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled. Lung volumes will be measured according to the body temperature, pressure, and saturated standard convention using the spirometer. Pre-bronchodilator spirometry will be performed in the absence of albuterol/salbutamol or at least 6 hours after the last dose of albuterol/salbutamol.
Secondary Outcomes
- Percent change from baseline in post-bronchodilator percent predicted Forced Vital Capacity (FVC) value(Week 4 and Week 12)
- Percent change from baseline in pre-bronchodilator percent predicted Forced Expiratory Flow (FEF) 25-75 value(Week 1, Week 2, week 4, Week 8, and Week 12)
- Percent change from baseline in post-bronchodilator percent predicted Forced Expiratory Flow (FEF) 25-75 value(Week 4 and week 12)
- Percent change from baseline in pre-bronchodilator percent predicted Forced Expiratory Volume in 1 second/Forced Vital Capacity (FEV1/FVC) value(Week 1, Week 2, Week 4, Week 8, and Week 12)
- Percent change from baseline in post-bronchodilator percent predicted Forced Expiratory Volume in 1 second/Forced Vital Capacity (FEV1/FVC) value(Week 4 and Week 12)
- Change from baseline to Week 12 in Asthma Daily Diary (ADD) data(Week 12)
- Number of participants with worsening of asthma(From baseline (Week 0) to Week 12)
- Time to worsening of asthma(From baseline (Week 0) to Week 12)
- Percent change from baseline in pre-bronchodilator percent predicted Forced Expiratory Volume in 1 second (FEV1) value(Week 1, Week 2, Week 4, and Week 8)
