Up to 35 evaluable subjects are planned to be included in the study. Eligible subjects must be on stable treatment with physician prescribed ivacaftor (Kalydeco®) for at least 28 days at the baseline visit. They will be randomized in a 2:2:1 ratio to receive one of two active doses of GLPG2222 (150 mg q.d. or 300 mg q.d.) or placebo q.d. administered for 29 days. Subjects will be in the study for a minimum of 6 weeks and a maximum of 10 weeks, from screening until the follow-up visit.

Since 2016, the French patients homozygous for the p.Phe508del mutation and older than 12 years are able to be treated with the association LUMACAFTOR-IVACAFTOR and this French authorization is being extended for 6-11 years old children (while the European Commission has already granted an extension of the Marketing Authorization for lumacaftor/ivacaftor to include 6-11 years old children with cystic fibrosis since January 2018). Patients treated by lumacaftor/ivacaftor (or other ivacaftor new combinations) are closely monitored according to criteria established by the working group "New Therapeutic Approaches" of the French Society Cystic fibrosis. This study is a phase IV observational trial for a period of 1 year. In this context, the team aims at initiating a comprehensive monitoring of the lung and gut mycobiota and microbiota evolution under LUMACAFTOR-IVACAFTOR (or other ivacaftor combinations) treatment. This project is directly linked to the monitoring of cystic fibrosis patients who begin treatment with LUMACAFTOR-IVACAFTOR (or other ivacaftor combinations) in France. The pro- and eukaryotic microbiota analysis is based on the secondary use of sputum and stool samples associated with several clinical data of CF patients under ivacaftor combinations and follow-up during the 1st year of therapy. According to the French law, Lum-Iva-Biota project is a non-interventional study. It aims at demonstrating that changes in the hydration of secretions at the pulmonary and intestinal levels related to LUMACAFTOR-IVACAFTOR therapy (or other new generation of ivacaftor combinations) promote a change in the lung and gut mycobiota and microbiota profiles which may achieve the characteristics of the "healthy type" (in terms of composition, richness and diversity).

The aim of this project is to evaluate the psychological reshuffle induced by ORKAMBI. The particular focus of this study is the consequence of its introduction on anxiety, depression, quality of life and adherence to all cystic fibrosis (CF) treatment. To answer this question investigators will monitor the psychological function of CF adolescents and young adults treated with ORKAMBI and compare them to CF adolescents and young adults not treated with ORKAMBI.

In contrary to what is seen in FRT cells, rectal organoids of patients with a R334W mutation do respond to CFTR modulators ivacaftor and lumacaftor. The present study will investigate the response to modulators in organoids of 30 patients with CF and a R334W mutation, to allow further stratificaton for a future clinical trial assessing the clinical effect of ivacaftor/tezacaftor in patients with CF and a R334W mutation.
