Background: People with cystic fibrosis (PwCF) have experienced substantial improvements in health following use of cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapies. However, less is known about how modulator therapies impact well-being., Methods: We used a cross-sectional observational study to identify relationships between CFTR modulator therapies, health-related quality of life (HRQoL), and well-being. Adult PwCF and caregivers of children with CF completed the Wellness in the Modulator Era (Well-ME) survey between June 22 and July 31, 2022. HRQoL was measured with PROMIS Global 10/Global 7 + 2 Parent Proxy. We used a mixed methods analysis to compare experiences and concerns of PwCF who currently (n = 665), no longer (n = 51), or never (n = 184) took modulator therapy., Results: Adult PwCF taking a modulator (n = 416) reported better PROMIS global physical health than those who no longer (n = 37) or never took a modulator (n = 94) and better PROMIS global mental health than those who never took a modulator. Caregiver-reported HRQoL was similar across children with CF who currently, no longer, or never took a modulator. PwCF taking a modulator reported larger improvements in physical health, quality of life, social well-being, and treatment burden than those who no longer or never took a modulator. Nearly one-quarter (23 %) of PwCF taking modulator therapy reported worsening of mental well-being., Conclusions: This study expands our knowledge of well-being among PwCF in the CFTR modulator era as reported by patients and parents. Findings lay the groundwork for establishing future research priorities, policy efforts, and communications in areas that improve well-being for PwCF., Competing Interests: Declaration of competing interest The authors of this manuscript would like to disclose the following conflict of interest: E.A. reports a salary from the Cystic Fibrosis Foundation.
