E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the safety and tolerability of two doses of orally administered GLPG2222 in ivacaftor-treated adult subjects with CF harbouring one F508del CFTR mutation and a second gating (class III) mutation |
|
E.2.2 | Secondary objectives of the trial |
•To assess changes in sweat chloride as biomarker of CFTR ion channel function
•To assess changes in pulmonary function (FEV1)
•To assess changes in Cystic Fibrosis Questionnaire – Revised (CFQ-R)
|

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Subjects have the option to participate in a GLPG2222 and ivacaftor PK substudy and undergo 8-hour PK sampling within 7 days prior to Day 1 (after all eligibility criteria have been confirmed) and on Day 29 |
|
E.3 | Principal inclusion criteria |
1.Male or female subject ≥ 18 years of age, on the day of signing the Informed Consent Form (ICF).
2.A confirmed clinical diagnosis of CF.
3.One F508del mutation on one allele in the CFTR gene, a gating (class III) mutation (one of the following: G551D, G1244E, G1349D, G178R, G551S, S1251N, S1255P, S549N, or S549R) on the 2nd allele in the CFTR gene (documented in the subject’s medical record or CF registry).
4.Weight ≥ 40 kg.
5.Stable concomitant treatment for at least 4 weeks (28 days) prior to baseline (including physician prescribed ivacaftor (Kalydeco®) 150 mg b.i.d.).
6.Forced expiratory volume in 1 second (FEV1) ≥ 40% of predicted normal for age, gender and height at screening (pre- or post-bronchodilator).
|
|
E.4 | Principal exclusion criteria |
1.History of clinically meaningful unstable or uncontrolled chronic disease that makes the subject unsuitable for inclusion in the study in the opinion of the investigator.
2.Unstable pulmonary status or respiratory tract infection (including rhinosinusitis) requiring a change in therapy within 4 weeks of baseline.
3.Need for supplemental oxygen during the day, and >2 liters per minute (LPM) while sleeping.
4.History of hepatic cirrhosis with portal hypertension (e.g., signs/symptoms of splenomegaly, esophageal varices, etc).
5.Abnormal liver function test at screening; defined as aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) and/or alkaline phosphatase and/or total bilirubin (>1.5 times ULN (CTCAE Grade 2) and/or gamma-glutamyl transferase (GGT) ≥ 3x the upper limit of normal (ULN), and/or total bilirubin (>1.5 times ULN (CTCAE Grade 2).
6.Estimated creatinine clearance < 60mL/min using the Cockroft-Gault formula at screening.
