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.
