Their impact on quality of life (QoL) have been studied in numerous trials, but few data are available on QoL in patients receiving Elexacaftor\u2010Tezacaftor\u2010Ivacaftor (ETI), notably in children given its recent authorization for this age group.

The total QoL score at baseline ([mean (SD)] children: 74.07 [10.86]; caregivers: 73.21 [10.38]) reflected severe disease impact, particularly regarding treatment burden in the children's perspective (63.28 [21.04]) and digestive domains in the caregivers' perspective (digestive symptoms: 66.67 [17.37]; eating disorder: 67.54 [32.14]; weight: 61.40 [33.82]). At M3, there was a significant increase in reported QoL (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.0001), particularly regarding physical domains. Emotional\/social\/school domains barely showed improvement. Although QoL mean scores were comparable between children and caregivers' groups, they were poorly correlated within the same family. Homozygous F508del genotype was associated with better QoL improvement at M3 compared to composite heterozygous genotypes (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>ETI treatment has a significant impact on children's QoL, particularly in physical health domains.
