Lived experiences of individuals with cystic fibrosis on CFTR-modulators.

Background: CFTR-modulators are a category of drugs that facilitate trafficking and opening of the abnormal CFTR protein in individuals with cystic fibrosis (CF) who have certain genetic mutations. Clinical trial data show that individuals taking CFTR-modulators have increased or stable lung function (FEV) as well as reduced frequency of pulmonary exacerbations. There are no data on whether CFTR-modulators influence psychosocial aspects of the lives of individuals with CF. The purpose of this qualitative study was to explore how the introduction of CFTR-modulators has affected individuals' lived experiences outside of clinical health variables; that is, to explore whether there is a relationship between using CFTR-modulator drugs and the psychological and social aspects of the lives of individuals with CF, including: career, relationships, family planning and psychological functioning.

Methods: Eight men and women with CF ages 24-32, with a history of taking any approved CFTR-modulator for at least six months, were recruited from an adult CF center. A semi-structured interview guide was used to interview the participants. The data were coded using a grounded theory approach with an iterative methodology.

Results: Four themes emerged from the data: stability, identity, potentiality, and hope.

Conclusions: Although these themes cannot be generalized to all individuals with CF, this study provides preliminary data for how CFTR-modulators may influence an individual with CF's outlook on life and that these individuals are feeling hopeful about the future.
