Trial Outcomes & Findings for A Study of the Comparable Efficacy and Safety of Pulmozyme (Dornase Alfa) Delivered by the eRapid Nebulizer System in Patients With Cystic Fibrosis (NCT NCT01712334)

NCT ID: NCT01712334

Last Updated: 2014-05-01

Results Overview

Spirometry was performed according to American Thoracic Society standards. FEV1 is the amount of air that is forced out of the lungs in one second and was measured at the end of each 2-week treatment period. The percent predicted FEV1 was calculated as: Percent predicted FEV1 =FEV1 (L) / Predicted FEV1 (L) ×100.

Participant Flow

99 patients were enrolled. 96 unique patients entered the run-in period including 3 patients who entered the run-in period twice.

Patients received dornase alfa (Pulmozyme®) by LC Plus nebulizer in the 2-week run-in period prior to randomization. A total of 86 unique patients were randomized in the study in 87 randomization events. Of the randomized patients, 85 patients completed the study in two treatment sequences.

PRIMARY outcome

Timeframe: At the end of each 2-week treatment period

Population: Modified Intent-to-Treat (mITT) population included all randomized participants with baseline and endpoint FEV1 values for both treatment periods.

Spirometry was performed according to American Thoracic Society standards. FEV1 is the amount of air that is forced out of the lungs in one second and was measured at the end of each 2-week treatment period.

PRIMARY outcome

Timeframe: 4 Weeks

Population: Safety population included all randomized participants who received treatment.

An adverse event was considered any unfavorable and unintended sign, symptom, or disease associated with the use of the study drug, whether or not considered related to the study drug. Preexisting conditions that worsened during the study and laboratory or clinical tests that resulted in a change in treatment or discontinuation from study drug were reported as adverse events.
