Overview

RETRIAL is a multi-site observational study of people with Cystic Fibrosis (PWCF) ages 6 and up starting the new triple-therapy modulator (vanzacaftor/tezacaftor/deutivacaftor (VTD)), after having experienced neuropsychiatric events and/or liver injury while taking elexacaftor/tezacaftor/ivacaftor (ETI) that resulted in a modification or discontinuation of standard ETI dosing.

Description

RETRIAL is a prospective, longitudinal, observational, multi-site study of people with Cystic Fibrosis (PWCF) ages 6 and up who had to either change how they took or stop taking elexacaftor/tezacaftor/ivacaftor (ETI) due to new or worsening mental health/cognitive symptoms (such as depression, anxiety, mood, sleep, and/or brain fog/memory problems) and/or liver issues (elevated liver enzymes) while taking the standard dose, and who plan to start taking vanzacaftor/tezacaftor/deutivacaftor (VTD).

  • Eligible for VTD and intending to take it
  • Experienced new or worsening mental health symptoms after initiating ETI, which led to one of the following changes in treatment to currently taking:

RETRIAL-LIVER:

  • A person with CF age 6 years and up
  • Eligible for VTD and intending to take it
  • Experienced drug-induced liver injury (as defined by local care team) after initiating ETI, which led to one of the following changes in treatment to currently taking:
    1. no modulators; or
    2. a modulator other than ETI; or
    3. a reduced or altered dose of ETI;
  • Willing to delay first VTD dose for short period of time to complete the Baseline assessments
  • Has access to a smart device (phone, tablet, etc.) capable of receiving messages with survey links
