Elexacaftor/tezacaftor/ivacaftor (ELX/TEZ/IVA) was given US Food and Drug Administration approval based on its therapeutic benefits to treat patients with cystic fibrosis (CF) who had at least 1 allele of the CF transmembrane conductance regulator (CFTR) with phenylalanine deleted at position 508 (F508del). The increase in genotyping studies has increased the frequency of use of CFTR modulators; however, severe allergic reactions to CFTR modulators have also been described. It is critical to avoid the offending medication and select alternative treatments while dealing with drug allergies.

Background: Phase 3 trials of elexacaftor/tezacaftor/ivacaftor (ELX/TEZ/IVA) combination treatment in people with cystic fibrosis (CF) with ≥1 F508del-CFTR allele showed profound short-term effects on lung function, weight, and pulmonary exacerbations (PEx). The authors conducted a 12-month study to add evidence on the real-world long-term effectiveness and safety of CFTR modulator therapy with ELX/TEZ/IVA in Portuguese CF adult population.
Methods: Ambispective, multicentre, observational, real-life study involving all the Portuguese CF Reference Centres.

Cystic fibrosis transmembrane conductance regulator modulators are the only available treatment for cystic fibrosis. Although elexacaftor/tezacaftor/ivacaftor (ELX/TEZ/IVA) is well-tolerated, rash has been reported as very frequent. In severe rashes, ELX/TEZ/IVA withdrawal is necessary, leading to clinical deterioration.

In the last 10 years, the care of patients with cystic fibrosis (CF) has been revolutionized with the introduction of (CFTR) modulator drugs, with a major impact on symptoms and life expectancy, especially considering the newest and highly effective elexacaftor/tezacaftor/ivacaftor (ELX/TEZ/IVA) therapy. Conversely, adverse effects are relatively frequent, with some being life-threatening, such as severe hepatitis. Clinical trials on children starting CFTR modulators have reported transaminase elevations >3× upper limit of the norm in 10%-20% of patients, whereas real-life studies have reported discontinuation rates three times higher than those observed in phase 3 trials.

Objective: Treatment with cystic fibrosis transmembrane conductance regulator (CFTR) modulators in individuals with cystic fibrosis (CF) has brought a significant change in forced expiratory volume in 1 second (FEV) and clinical parameters. However, it also results in weight gain. The aim of our study is to evaluate the effect of CFTR modulator treatment on body composition, measured by computed tomography (CT).
