Abstract
The combination of medication containing elexacaftor, ivacaftor, and tezacaftor (EIT) has dramatically impacted the treatment and prognosis for patients with cystic fibrosis (CF). Lung function, weight, and self-reported quality of life have improved for many of these patients, but little is known about whether this treatment will have a beneficial effect in preventing morbidity and/or mortality from respiratory infections such as COVID-19. EIT received Food and Drug Administration (FDA) approval shortly before the first cases of COVID-19 appeared in the United States. We performed an analysis using the TriNetX (Cambridge, MA, USA) research database to determine if patients being treated with EIT who became infected with COVID-19 experienced significantly different outcomes compared to patients who were not receiving it.
