Perceptions and Intentions Around a Change in CF Treatment
Official title: Perceptions and Expectations of Patients Regarding a Change in Treatment in Cystic Fibrosis (PERCE-MUCO)
Run by Fondation Ildys · NCT07885410 · Data updated 2026-11-12
This study asks adults with cystic fibrosis currently on ETI whether they would switch to VTD if their doctor offered it and what factors influence that decision.

Is this trial a fit for you?
✓Likely a good fit
Adults with cystic fibrosis who are on ETI for at least 3 months or who have had ETI discontinued for medical reasons, and who have not already started VTD.
✕Probably not a fit
Patients already on VTD or those unwilling to share data for research may not benefit from study findings.

What this trial studies
PERCE-MUCO is a multicenter observational study using mixed methods to explore how adults with CF perceive a potential switch from ETI to VTD, including their expectations, satisfaction, and adherence. The project collects quantitative data via a purpose-built questionnaire plus routine CFQ-R 14+ and Morisky-8 measures, and qualitative insights from semi-structured interviews at a French CF center. The primary goal is to determine the proportion who would accept a switch and identify determinants of acceptance. Secondary aims examine quality of life relationships with switching intent, tolerability and adherence impacts, and the role of an advanced practice nurse during a potential transition. The study will describe barriers and facilitators to switching from patient and clinical perspectives.
Why it matters
Potential benefit: If successful, insights could guide patient-centered decision-making and support strategies during consideratio ns of switching CFTR modulator therapies.
How similar studies have gone: Similar observational work in CF has shown that patient perceptions can influence treatment switching decisions and adherence.
