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.
