Study of Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of QBW251 in Subjects With Bronchiectasis

Bronchiectasis Clinical Trial

Official title: A Randomized, Subject- and Investigator-blinded, Placebo-controlled, Parallel Group Study to Assess the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of QBW251 in Patients With Bronchiectasis

Status Terminated

Clinical Trial Summary

The purpose of this study is to determine whether potentiating the cystic fibrosis transmembrane conductance regulator (CFTR) with QBW251 in patients with bronchiectasis will demonstrate clinical safety and efficacy related to improved mucociliary clearance with reduced bacterial colonization as potential drivers of airway obstruction, reduced airway inflammation, exacerbations and mucus load, improved lung function, clinical symptoms and quality of life to support further development in bronchiectasis.

Clinical Trial Description

This is a randomized, subject- and investigator-blinded, placebo-controlled, parallel-group study investigating the preliminary efficacy and safety of QBW251 administered orally for 12 weeks in subjects with bronchiectasis. Approximately 72 subjects will be randomized in a 1:1 ratio to receive either QBW251 or placebo in order to achieve 60 subjects who complete the treatment period based on the assumption of a 16% drop-out rate. The sample size assumptions will be reviewed in an interim analysis in a blinded manner when approximately 14 subjects complete the treatment period. The study consists of the following periods: Screening, baseline/Day 1, treatment period, and end of study assessments (EOS) visit followed by an additional post-treatment safety follow up via phone call. The total duration for each patient in the study is up to approximately 18 weeks. ;
