What this Trial Is About
Shortness of breath (dyspnea) during exercise is a major source of distress and is a commonly reported symptom in patients with cystic fibrosis (CF). A recent drug treatment option known as Trikafta, which contains elexacaftor, tezacaftor, and ivacaftor, may be used in patients with CF to help improve lung health. However, the effects of this combination therapy on dyspnea and exercise performance, a known predictor of survival in CF, are not clear. The investigators aim to understand the effects of Trikafta on these symptoms and to gain new insight into the potential health improvements in CF from using this treatment option.
