Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
Brief 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.
