A Study of the Safety and Effectiveness of JNJ-39758979 in the Treatment of Adults With Persistent Asthma
- Registration Number
- NCT00946569
- 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.

- Primary Outcome Measures
Name Time Method Percent change from baseline to Week 12 in pre-bronchodilator percent predicted Forced Expiratory Volume in 1 second (FEV1) value 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 Outcome Measures
Name Time Method Percent change from baseline in post-bronchodilator percent predicted Forced Vital Capacity (FVC) value Week 4 and Week 12 FVC 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. FVC is the volume of air that can forcibly be blown out after full inspiration and is measured in liters. Post- bronchodilator spirometry will be performed after 15 to 30 minutes administration of 360 micrograms (4 puffs) of albuterol/salbutamol via metered-dose inhaler.
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 FEF 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. FEF is the speed (or flow) of air coming out of the lung during the middle portion of a forced expiration. It is generally defined by what fraction remains of the forced vital capacity (FVC), usually 25-75 percent (FEF25-75%). Pre-bronchodilator spirometry will be performed in the absence of albuterol/salbutamol or at least 6 hours after the last dose of albuterol/salbutamol.
Percent change from baseline in post-bronchodilator percent predicted Forced Expiratory Flow (FEF) 25-75 value Week 4 and week 12 FEF 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. FEF is the speed (or flow) of air coming out of the lung during the middle portion of a forced expiration. It is generally defined by what fraction remains of the forced vital capacity (FVC), usually 25-75 percent (FEF25-75%). Post- bronchodilator spirometry will be performed after 15 to 30 minutes administration of 360 micrograms (4 puffs) of albuterol/salbutamol via metered-dose inhaler.
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 FEV1/FVC is the ratio of FEV1 to FVC and 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. FEV1 is the volume of air that can forcibly be blown out in one second, after full inspiration and FVC is the volume of air that can forcibly be blown out after full inspiration. Pre-bronchodilator spirometry will be performed in the absence of albuterol/salbutamol or at least 6 hours after the last dose of albuterol/salbutamol.
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 FEV1/FVC is the ratio of FEV1 to FVC and 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. FEV1 is the volume of air that can forcibly be blown out in one second, after full inspiration and FVC is the volume of air that can forcibly be blown out after full inspiration. Post bronchodilator spirometry will be performed after 15 - to 30 minutes administration of 360 micrograms (4 puffs) of albuterol/salbutamol via metered-dose inhaler.
Change from baseline to Week 12 in Asthma Daily Diary (ADD) data Week 12 ADD is an electronic peak flow/diary device to score asthma symptoms twice daily (12 hours interval). Upon awakening, participants are asked to record 3 peak expiratory flow rates (PEFR), number of puffs of albuterol/salbutamol in the past 24 hours and indicate whether they had night time awakenings requiring albuterol/salbutamol. In the evening, participants are asked to record 3 PEFRs and rate asthma symptoms using a 6-point scale (0 = No symptoms and 5 = symptoms so severe that I could not go to work or perform normal daily activities). Higher scores indicate worsening.
Number of participants with worsening of asthma From baseline (Week 0) to Week 12 Worsening of asthma is defined as any episode of: 1) decrease in Forced Expiratory Volume in 1 second (FEV1) of greater than or equal to 20 percent compared to baseline FEV1, 2) requiring treatment with systemic corticosteroids, 3) requiring treatment with any other prohibited asthma medication including inhaled corticosteroids, 4) requires emergency room treatment or hospitalization, and 5) life-threatening asthma attack that requires intubation or intensive care unit admission.
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 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.
