Trial Outcomes & Findings for A Study of Pulmozyme® (Dornase Alpha) in 3- to 5-Year-Old Patients With Cystic Fibrosis (NCT NCT00680316)

NCT ID: NCT00680316

Last Updated: 2017-01-12

Results Overview

The fundamental principle of forced oscillometry is that lung function can be assessed by measuring changes in pressure and flow in response to external pressure applied at the airway opening. Reactance is complex measure that incorporates the changes in pressure and volume and the rate of these changes in response to pressure oscillations at a specific frequency. (8Hz was used for the primary endpoint). Reactance is thought to reflect the elastic properties of the lung.

PRIMARY outcome

Timeframe: from Visit 2 to Visit 3 (16 +/- 2 days)

Population: Children were unable to perform forced oscillometry (FOT) or did not remain stable during the study. No efficacy analyses were performed because no patients had complete (pre- or post-treatment) data for pulmonary function tests, including FOT.

The fundamental principle of forced oscillometry is that lung function can be assessed by measuring changes in pressure and flow in response to external pressure applied at the airway opening. Resistance is complex measure that incorporates the lack of changes in pressure and volume and the rate of these changes in response to pressure oscillations at a specific frequency. (10Hz was used for the secondary endpoint).

The CFQ-R for Preschoolers and the CFQ-R for Parents of Preschoolers was designed specifically to measure the impact of CF for patients with a diagnosis of CF. Each question is answered using a 4-point Likert scale. In order to calculate the domain/symptom scale scores, the following algorithm is followed * Re-number items which have been reverse coded * Calculate the mean of the items to be included. If more than half of the items are missing, then the score is considered missing * Re-scale to result in a scaled score which ranges from 0 to 100, with higher scores indicating better health
