E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Compare the difference in PRAGMA-CF total percent disease (%Dis) between HS and IS study arm at end of study (48 weeks), measured from standardized chest CT. |
Comparar la puntuación del % total de PRAGMA-CF (proporción de volumen del pulmón con enfermedad estructural) entre ambos brazos medida mediante una TC de tórax en la semana 48. |
|
E.2.2 | Secondary objectives of the trial |
Compare the differences in PRAGMA-CF subscores: the volume proportions of the lung with bronchiectasis (%Bx) and trapped air (%TA), as well as airway dimensions as measured using the AA method measured from chest CT images at 48 weeks between treatment arms. Elucidate the 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. |
1. Comparar las subpuntuaciones del PRAGMA-CF en ambos brazos de tratamiento, así como los AA ratios medidos mediante una TC de tórax en la semana 48 2. Comparar los cambios de LCI, medido por N2 MBW, en ambos grupos desde el inicio a la semana 48 semana 3. Explicar la relación entre las medidas transversales y longitudinales de la enfermedad pulmonar estructural evaluada mediante TC de tórax (PRAGMA-CT %Dis; %Bx; %TA) y el método AA, el LCI calculado mediante MBW y resultados clínicos (exacerbaciones pulmonares, calidad de vida) durante las 48 semanas de tratamiento. |
