Safety, Pharmacokinetics and Pharmacodynamics Study of Inhaled QBW276 in Patients With Cystic Fibrosis

This is a study of multiple doses of inhaled QBW276 in patients with cystic fibrosis on top of standard of care. The study was divided into 3 Cohorts. Cohorts 1 and 2 are designed to be a randomized, double-blind, placebo-controlled, parallel arm, multiple dose study to assess the safety, tolerability, pharmacokinetics, and preliminary efficacy of inhaled QBW276 over 1 week (cohort 1) or 2 weeks (cohort 2) in patients with cystic fibrosis regardless of their genotype. The study was terminated after Cohort 2 due to the resource issues.
