Clinical Trial Summary

The purpose of this study is to assess whether inhalation of 7% hypertonic saline (HS) twice daily for 48 weeks reduces structural lung disease as assessed by computed tomography (CT) in comparison with inhalation of 0.9% isotonic saline (IS) in preschool children (ages 3 to 6) with cystic fibrosis.

Description:

Several observational studies have shown that cystic fibrosis (CF) patients less than or equal to 6 years of age have clinically silent airway damage. There is growing interest in early initiation of therapies to prevent or delay the progression of this lung disease in CF. In SHIP-CT, the investigators will evaluate treatment effects of HS relative to IS on measures of structural lung disease obtained from chest CT using a novel scoring system sensitive to early lung changes, the Perth-Rotterdam Annotated Grid Morphometric Analysis method for CF (PRAGMA-CF), that quantifies the volume percentage of diseased airways (%Dis), bronchiectasis (%Bx), and trapped air (%TA). As a secondary evaluation of structural airway damage, the investigators will use an image analysis system to measure airway dimensions relative to adjacent arteries (AA-system). Longitudinal changes in CT measures will also be compared to changes in lung function measured by the lung clearance index (LCI) obtained by N2 Multiple Breath Washout (MBW) and to clinical outcomes.

The primary hypothesis is that HS will reduce structural lung disease as assessed by the PRAGMA-CF computed tomography score relative to IS during the 48-week treatment period among preschool children with CF.

SHIP-CT is a parallel study to SHIP001 (ClinicalTrials.gov Identifier NCT02378467). The primary hypothesis of SHIP001, which runs in North America, is that compared to IS, HS will improve the LCI, a measure of ventilation heterogeneity, during the 48-week treatment period among preschool children with CF. The SHIP-CT study (SHIP002) will use a nearly identical study design as the SHIP001 study, with similar eligibility criteria and treatment arms, to determine whether HS reduces structural lung disease as measured by chest computed tomography (CT), in addition to stabilizing or improving functional outcomes as measured by LCI.

This is a multicenter, randomized, double-blind, controlled, parallel group trial assessing structural lung disease in children with CF ages 3 to 5 at enrollment. Participants will be randomized 1:1 to receive 7% hypertonic saline (treatment arm) vs. 0.9% isotonic saline (control arm) administered twice daily via jet nebulizer for 48 weeks. Study visits will occur at screening, enrollment, and at Weeks 12, 24, 36, and 48. Parents or the legal guardian will be contacted at Weeks 1, 4 and 8 to document changes in health status, adverse events, concomitant medications/treatments, and encourage study treatment compliance. Parents or the legal guardian will also be contacted approximately every 6 weeks between visit 3, 4, 5, and 6 to address individual issues or concerns related to study treatment or study participation, and to document changes in health status, medications and treatments.

Total duration of participant participation will be up to 53 weeks. As enrollment will occur over approximately 18 months, total duration of the study is expected to be up to 30 months (18 months enrollment plus 12 months for the last participants to complete study participation).
