Background: Elexacaftor/tezacaftor/ivacaftor (ETI) is a highly effective therapy that improves lung disease in people with cystic fibrosis (pwCF), but its effect on glucose tolerance and insulin secretion is unclear.

Methods: PROMISE is a multicenter prospective, observational study of ETI in pwCF ≥12 years and at least one F508del allele. The PROMISE Endocrine sub-study (PROMISE-ENDO) enrolled participants at 10 CF Centers where hemoglobin A1c (HbA1c) was collected and 3-hour oral glucose tolerance tests (OGTT) conducted to examine glucose tolerance, glucose excursions, insulin secretory rates (deconvolution of C-peptide) and sensitivity (oral minimal model) prior to ETI and 12-18 months (mos) and 24-30 mos following ETI initiation.

Background: Recognizing the limitations of pre-market clinical data, regulatory authorities have embraced total product lifecycle management with post-market surveillance (PMS) data to assess medical device safety and performance. One method of proactive PMS involves the analysis of real-world data (RWD) through retrospective review of electronic health records (EHR). Because EHRs are patient-centered and focused on providing tools that clinicians use to determine care rather than collecting information on individual medical products, the process of transforming RWD into real-world evidence (RWE) can be laborious, particularly for medical devices with broad clinical use and extended clinical follow-up.

Article Synopsis
  • - The study investigates the effects of cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapies on health-related quality of life (HRQoL) and well-being among people with cystic fibrosis (PwCF) and their caregivers.
  • - Results show that adult PwCF currently on modulator therapy experience better physical and mental health compared to those who have stopped or never used the treatments, but some (23%) report declines in mental well-being.
  • - The findings aim to inform future research, policy, and communication efforts that could enhance the well-being of PwCF by understanding their experiences with modulator therapies.
