Study of GLPG1837 in Subjects With Cystic Fibrosis (G551D Mutation)

Summary

32 cystic fibrosis patients with the G551D mutation will be treated for 4 weeks, consisting of three consecutive treatment periods: two 1-week periods followed by one 2-week period, evaluating one dose of GLPG1837 each. After the treatment period, there is a 7-10 days follow-up period. During the course of the study, subjects will be examined for any side effects that may occur (safety and tolerability). Changes in sweat chloride will be assessed as biomarker from baseline onwards, and changes in pulmonary function (efficacy) will be explored throughout the study. The amount of GLPG1837 present in the blood (pharmacokinetics) will also be determined.
