A Review on the Use of Cystic Fibrosis Transmembrane Conductance Regulator Gene Modulators in Pediatric Patients

The literature surrounding the use of cystic fibrosis transmembrane conductance regulator-targeted pharmacotherapies in pediatric patients continues to evolve. These therapies represent a departure from symptom management and infection prevention, which have been the mainstay of cystic fibrosis management in pediatrics, to targeting the genetic defect present within these patients. This article reviews the clinical studies evaluating the safety and efficacy of ivacaftor, ivacaftor/lumacaftor, and ivacaftor/tezacaftor. These medications were initially studied in adults and adolescents but have begun to be studied in younger populations. Further investigation into the use of these drugs with different CFTR mutations and in younger age groups will continue to expand the number of patients who can benefit from these therapies.
