Trial Outcomes & Findings for Comparing Bronchodilation of Symbicort With and Without Valved Holding Chamber (Aerochamber Plus) (NCT NCT00915538)

NCT ID: NCT00915538

Last Updated: 2020-08-13

Results Overview

The mean FEV-1 (Forced Expiratory Volume 1 second) for each of the treatments (with and without valved holding chamber) in this crossover design were recorded at BL, 5, 10, 15, 30, 60, 120, 240. 480, 720 minutes (12 hrs) were plotted as a curve and the area under the curve was calculated. The measured results was mean liters/12 hours.

Measure
Group 1
n=16 Participants
The intervention in this group will inhalation from the pMDI containing budesonide/formoterol pMDI 160/4,5 2 inhalations as recommended in product PI (FDA approved product information)without a spacer. The pulmonary function tests (PFTs) will be collected at baseline and for a period of 12 hours post inhalation of 2 inhalation of budesonide /formoterol; pMDI160/5. pMDI budesonide/formotrol 160/4.5 is in group 1: The subjects will receive budesonide/formoterol pMDI 160/4.5 pMDI used in conventional fashion, and have pulmonary function measured over 12 hours. Symbicort 160/4.5 plus Aerochamber Plus icluded in group 2: Symbicort 160/4.5 will be administered through a valved holding chamber, Pulmonary functions will be measured over 12 hours.
Group 2
n=16 Participants
The intervention in this group will use the pMDI budesonide/formoterol 160/4.5 with a valve holding chamber spacer device (aerochamber plus)which is the intervention being studied The PFTs will be collected at baseline and for a period of 12 hours post inhalation of 2 inhalation of Symbicort 160/5. This is the intervention to be studied for comparison to the non-spacer inhalations.. pMDI budesonide/formotrol 160/4.5 is in group 1: The subjects will receive budesonide/formoterol pMDI 160/4.5 pMDI used in conventional fashion, and have pulmonary function measured over 12 hours. Symbicort 160/4.5 plus Aerochamber Plus icluded in group 2: Symbicort 160/4.5 will be administered through a valved holding chamber, Pulmonary functions will be measured over 12 hours.
The Mean Area Under the Curve (AUC) of Forced Expiratory Volume in One Second (FEV-1) Over 12 Hours, Measured (BL), 5, 10, 15, 60, 120, 240, 480, 720 Minutes. The Unit is Liters, and the AUC is in Liters.
2.77 Liters X hours
Interval 0.0 to 720.0
2.79 Liters X hours
Interval 0.0 to 720.0

SECONDARY outcome

Timeframe: 0,5,10,15,30,60,120,240,480,720 minutes

Population: This is a cross over design. 2 cohorts of 8 subjects will be tested in a cross over design, so that 16 measurements will be made for each intervention. This should give power of 0.8 for non inferiority equivalence study.

The ratio of the volumes in liters of FEV-1 to Forced vital capacity (FVC). This is reported as percent for each time point., Each time point will be compared.for the two interventions. This expressed as a percentage.
