Brief 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.

Condition or disease Intervention/treatment Phase
Bronchiectasis Drug: Active drug Drug: Placebo Phase 2

Detailed 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.

Primary Outcome Measures :
  1. Change from baseline in bacterial load Colony forming units (CFU/mL) of potentially pathogenic microorganisms in sputum at week 12 [ Time Frame: Baseline, 12 weeks ]
    Bacterial load is measured by the number of colony forming units (CFU/ml, 1 CFU/mL=1 CFU/g) of potentially pathogenic microorganisms in sputum


Secondary Outcome Measures :
  1. Proportion of subjects with absence of any colony forming units (CFU/mL) of potentially pathogenic bacteria sputum [ Time Frame: Baseline, 12 weeks ]
    Change from baseline on sputum bacterial clearance

  2. Quality of Life Questionnaire for Bronchiectasis (QOL-B) (Respiratory symptoms domain) [ Time Frame: Baseline, 12 weeks ]
    The Quality of Life Questionnaire for Bronchiectasis (QOL-B) is a disease-specific questionnaire developed for non-cystic fibrosis bronchiectasis. It covers 8 dimensions: physical functioning, role functioning, emotional functioning, social functioning, vitality, treatment burden, health perceptions, and respiratory symptoms. Each dimension is scored separately on a scale of 0 to 100, and higher scores represent better outcomes. Only the respiratory symptoms domain score is reported for this outcome measure.

  3. Fibrinogen plasma concentration [ Time Frame: Baseline, 12 weeks ]
    To assess the change from baseline of fibrinogen plasma

  4. Change in rescue medication use (salbutamol/albuterol) [ Time Frame: Baseline, 12 weeks ]
    To assess the effect of QBW251 compared to placebo after 12 weeks of treatment on rescue medication use

  5. FEV1 [ Time Frame: Baseline, 12 weeks ]
    To assess the effect of QBW251 compared to placebo after 12 weeks of treatment on spirometry (Forced Exploratory Volume in the first second).

  6. Airway wall [ Time Frame: Baseline, 12 weeks ]
    Change from baseline in airway wall after 12 weeks of treatment, as measured by high resolution computed tomography (HRCT).

  7. FVC [ Time Frame: Baseline, 12 weeks ]
    To assess the effect of QBW251 compared to placebo after 12 weeks of treatment on spirometry (Forced Vital Capacity).

  8. Cmax of QBW251 [ Time Frame: 1h, 2h, 3h, 4h, 6h and 8h post-dose on Days 1 and 28, and 3h post-dose on Day 56 and Day 84 ]
    Maximum (peak) plasma concentration of QBW251

  9. Ctrough of QBW251 [ Time Frame: Pre-dose Day 1, Day 28, Day 56, Day 84 ]
    Trough (pre-dose) plasma concentration of QBW251.

  10. Airway lumen [ Time Frame: Baseline, 12 weeks ]
    Change from baseline in airway lumen after 12 weeks of treatment, as measured by high resolution computed tomography (HRCT).

  11. Airway extent of global and regional air trapping [ Time Frame: Baseline, 12 weeks ]
    Change from baseline in the extent of global and regional air trapping after 12 weeks of treatment, as measured by high resolution computed tomography (HRCT)

  12. AUC of QBW251 [ Time Frame: Pre-dose, 1h, 2h, 3h, 4h, 6h and 8h post-dose on Day 1 and Day 28 ]
    Area under the concentration-time curve (AUC) of QBW251

Influenzae, M catarrhalis, S aureus, S pneumoniae, Enterobacteriaceae, P aeruginosa, Stenotrophomonous maltophilia, or any potential pathogenic non-fermenting Gram negative bacteria measured by dilution/outgrowth).
