E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
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 |
|
E.2.2 | Secondary objectives of the trial |
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. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Diagnosis of CF as evidenced by one or more clinical features
consistent with the CF phenotype or positive CF newborn screen
AND one or more of the following criteria:
a) A documented sweat chloride ≥ 60 mEq/L by quantitative
pilocarpine iontophoresis (QPIT)
b) A documented genotype with two disease-causing
mutations in the CFTR gene
2. Informed consent by parent or legal guardian
3. Age ≥ 36 months and ≤72 months at screening visit
4. Ability to comply with medication use, study visits and study
procedures as judged by the site investigator
5. Ability to cooperate with chest CT at the enrolment visit as
determined by the lung function technician |
|
E.4 | Principal exclusion criteria |
Acute intercurrent respiratory infection, defined as an increase in
cough, wheezing, or respiratory rate with onset within 3 weeks
preceding screening or enrolment visit
3. Acute wheezing at screening or enrolment visit
4. Oxygen saturation < 95% (<90% in centres located above 4000 feet
elevation) at screening or enrolment visit
5. Other major organ dysfunction, excluding pancreatic dysfunction
6. Physical findings that would compromise the safety of the
participant or the quality of the study data as determined by site
investigator
7. Investigational drug use within 30 days prior to screening or
enrolment visit
8. Treatment with inhaled HS at any concentration within 30 days prior
Chest CT within 8 months prior to screening or enrolment visit
9. Initiation (i.e. new prescription) of any inhaled hydrating agent such
as mannitol or mucolytic agents such as dornase alpha within 30
days prior to the screening or enrolment visit
10. Chronic lung disease not related to CF
11. Inability to tolerate first dose of study treatment at the enrolment
visit |

E.5 End points |
E.5.1 | Primary end point(s) |

of
study (48 weeks), adjusted for baseline, measured from standardized
chest
CT. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | 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. |
