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. Adult patients on treatment with ELX/TEZ/IVA combination outside clinical trials were included. Demographics, efficacy, and safety variables on the first 12 months of treatment were compared with the pre-treatment year.
RESULTS: 132 adult people with CF were included, of which 119 completed 12 months treatment (mean duration of treatment 21.5 months). Mean age was 31.7 ± 11.0 years, 53 % patients were homozygous for the F508del variant, baseline sweat chloride was 86.7 ± 25.9 mmol/L and pre-treatment percent-predicted FEV1 was 77.9 ± 19.7 %. At 1 year, mean absolute change from baseline in FEV1 was +0.46L (95 % CI: 0.37, 0.55; p < 0.001) and +13.9 percentage points (95 % CI: 11.5, 16.2; p < 0.001). PEx episodes decreased by 78 % (p < 0.001) and hospitalizations for PEx decreased by 91.4 % (p < 0.001). Body mass index (BMI) increased 1.2 kg/m2 (95 % CI: 0.9, 1.5; p < 0.001). Mean sweat chloride variation was -44.5 mmol/L (95 % CI: -49.8, -39.2; p < 0.001). No correlation was found between sweat chloride and lung function (r = -0.116, p = 0.335). There were no major safety concerns. Of note, headache was reported in 7.6 % and neuropsychiatric manifestations occurred in 12.6 % treated patients, being anxiety and depressive disorders the most common.
CONCLUSIONS: ELX/TEZ/IVA treatment in Portuguese adults with CF was associated with significant improvement in lung function, a drop in PEx and PEx-related hospitalizations and increase in BMI at 12 months and was well tolerated. These results add knowledge to our understanding of clinical benefits and tolerability of ELX/TEZ/IVA. Careful evaluation of adverse effects of ELX/TEZ/IVA therapy and its determinants, mainly concerning mental health, are a research priority.
