1 G551D Observational Study (GOAL)-Expanded to Additional Genotypes and Extended for Long Term Follow up (GOAL-e2)

The goal of this research study is to collect blood and urine samples from people who have either the R117H type of CF or the non-G551D gating type of CF to be kept for future research.We will also use some of the collected blood to measure the number of neutrophils.

16 Response to CFTR-modulators in Intestinal Organoids of Patients With CF Having at Least One R334W Mutation

In contrary to what is seen in FRT cells, rectal organoids of patients with a R334W mutation do respond to CFTR modulators ivacaftor and lumacaftor. The present study will investigate the response to modulators in organoids of 30 patients with CF and a R334W mutation, to allow further stratificaton for a future clinical trial assessing the clinical effect of ivacaftor/tezacaftor in patients with CF and a R334W mutation.
