Conditions
Brief summary
The study estimates the efficacy and safety of MK0476 and aminophylline intravenous administration in adult participants with acute asthma.
Interventions

Eligibility
Inclusion criteria
* Adult participants with acute asthma attacks
Exclusion criteria
* Participant has any known or suspected, acute or chronic cause for their pulmonary symptoms other than asthma (e.g., COPD, chronic heart failure, etc.). * Participant has a smoking habit (15 cigarettes per day) within a month prior to screening period, and/or has a smoking history (20 cigarettes per day) of more than 15 years. * Participant has a disease of the cardiovascular, hepatic, renal, hematologic systems, or other severe disease.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline in Forced Expiratory Volume in One Second (FEV1) Within the First 60 Minutes After Administration | Baseline and 60 minutes after study drug administration | The time weighted average change from Baseline in Forced Expiratory Volume in One Second (FEV1) over the first 60 minutes after study drug administration (average change FEV1 (0-60 min)). Baseline (pre-allocation) was the last measurement obtained during the screening period. |
Participant flow
Recruitment details
Phase III. Studied period: March 12, 2007 (date study drug was first administered to first participant) to August 1, 2007 (date study drug was last administered to last participant). Study was conducted at 31 clinical sites.
Pre-assignment details
Participants with acute exacerbation of bronchial asthma received standard treatments of inhaled β-agonist or oxygen inhalation to treat the acute exacerbations during the 60 minutes in the screening period before the study randomization.

Outcome results
Change From Baseline in Forced Expiratory Volume in One Second (FEV1) Within the First 60 Minutes After Administration
The time weighted average change from Baseline in Forced Expiratory Volume in One Second (FEV1) over the first 60 minutes after study drug administration (average change FEV1 (0-60 min)). Baseline (pre-allocation) was the last measurement obtained during the screening period.
Time frame: Baseline and 60 minutes after study drug administration
Population: Per Protocol Set (PPS): subset of participants who comply with the protocol sufficiently to ensure that these data will likely exhibit effects of treatment, according to the underlying scientific model. Aminophylline 250 mg - 1 participant with no FEV1 data at 60 minutes was excluded from the analysis.
