Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This qualitative longitudinal study is designed to elicit and thematically analyze the perspectives of SIMPLIFY subjects about treatment withdrawal research and treatment burden in the context of triple combination CFTR (Cystic Fibrosis Transmembrane Conductance Regulator) modulator therapy (TCT). Cohorts will be determined based on sub-groups of the assigned treatment arms from the SIMPLIFY study. Participants will be asked to participate in two interviews; the first interview will be conducted at the completion of the SIMPLIFY study and the second interview will be conducted approximately 4 months after the first interview. Trained research staff will conduct the semi-structured interviews that will be audio-recorded and transcribed for thematic analysis. Each interview should last between 30-60 minutes.
