Asthma Clinical Trial
— CAMPOfficial title:
Childhood Asthma Management Program
The purpose of this study is to evaluate the long term effects of anti-inflammatory therapy compared to bronchodilator therapy on the course of asthma, particularly on lung function and bronchial hyperresponsiveness, and on physical and psychosocial growth and development.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Pulmonary Function as Measured by Normalized FEV1 Over a 4-6 Year Period | Change in FEV1 % of predicted, post-bronchodilator use, from baseline to the end of treatment (4-6 years after randomization). Percent predicted determined from three separate published sets of reference equations for white, black, and Hispanic children - see NEJM 343: 1054-1062, 2000 for more details and references. | At the end of treatment, 4-6 years from baseline assessment | No |
Secondary | Bronchial Responsiveness to Serial Methacholine Concentrations Inhaled Into the Lungs | Bronchial responsiveness to serial concentrations of inhaled methacholine solution (mg/ml) as measured by serial ratios of follow-up to baseline FEV1 (forced volume of air expired from the lungs in one second). A dose-response curve is calculated from the serial ratios in relation to the serial concentrations to determine PC20, the concentration associated with a 20% drop from baseline in FEV1; this PC20 is the outcome measure with units mg/ml of methacholine. | 4-6 years from baseline | No |
Secondary | Change From Baseline in the Rate of Asthma Free Days | Change from baseline proportion of days without asthma symptoms or other asthma related events to proportion of days during the 4-6 years of follow-up. Asthma free days were determined from daily asthma diaries kept from baseline to the end of treatment, 4-6 years later. | 4-6 years from baseline | No |
Secondary | Need for Urgent Care for Asthma | Counts during the period of treatment (4-6 years) of visits to emergency rooms or equivalent urgent care settings for asthma treatment. | 4-6 years from baseline | No |
Secondary | Mortality | Counts of deaths from asthma. | 4-6 years from baseline | Yes |
Secondary | Change in Height From Baseline to End of Treatment, 4-6 Years Later | Change in standing height from baseline to end of treatment. Standing height is measured three times without shoes using a calibrated Harpenden stadiometer; the average of the three repeated heights to the nearest 0.1 cm is the height measure at either baseline or end of treatment. | 4-6 years from baseline | No |
Secondary | Standardized Depression Scale -- Children's Depression Inventory | Change in total score on the Children's Depression Inventory from baseline to the end of treatment, 4-6 years later. The total score ranges from 0-54 with higher scores indicating greater levels of depression. | 4-6 years from baseline | No |
