Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Compare the PRAGMA-CF total percent disease (%Dis) score (the volume proportion of the lung with structural airways disease) measured from standardized chest CT at 48 weeks between treatment arms;Secondary Objective: Compare the PRAGMA-CF sub-scores %Bx (the volume proportion of the lung with bronchiectasis) and %TA (the volume proportion of the lung with trapped air), as well as airway-to-artery ratios (AA ratios) measured from chest CT images at 48 weeks between treatment arms 3. Compare the change in LCI, measured by N2 MBW, from baseline to 48 weeks between treatment arms. 4. Elucidate the cross-sectional and longitudinal relationships between measures of structural lung disease evaluated by chest CT (PRAGMA-CF (%Dis, %Bx, %TA) and AA method (AA ratio and airway dimensions), LCI measured by multiple breath washout and clinical outcomes (pulmonary exacerbations, health-related quality of life) over the 48-week treatment period.;Primary end point(s): The difference in PRAGMA-CF %Dis between HS and IS study arm at end of study (48 weeks), adjusted for baseline, measured from standardized chest CT.;Timepoint(s) of evaluation of this end point: During the whole study. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): i)The difference in PRAGMA-CF sub-scores, %Dx and %TA, between the baseline CT and the 48 week CT. ii) The absolute number of airways, airway dimensions and AA ratios from TLC CTs, acquired at the 48-week visit. 2. The difference in LCI, measured by N2 MBW, from baseline to 48 weeks 3. Cross-sectional and longitudinal relationships between primary and secondary PRAGMA-CF outcomes (%Dis, %Bx and %TA) and MBW outcomes (LCI), airway dimensions and PRAGMA-CF and MBW outcomes, as well as CFQ-R scores and PRAGMA-CF and MBW outcomes.;Timepoint(s) of evaluation of this end point: During the whole study. | — |
