Clinical Effectiveness of Lumacaftor/Ivacaftor in Patients with Cystic Fibrosis Homozygous for F508del-CFTR. A Clinical Trial.

ABSTRACT: Rationale: The combination of lumacaftor (LUM) and ivacaftor (IVA) is an approved CFTR (cystic fibrosis [CF] transmembrane conductance regulator) modulator treatment for homozygous F508del patients with CF.Objectives: To evaluate the effectiveness of LUM/IVA in children (6 yr or more) and adults (more than 18 yr) in a postapproval setting.Methods: This longitudinal cohort study, performed at 38 centers in the U.S. CF Therapeutics Development Network, enrolled homozygous F508del patients with CF ages 6 years old and older with no prior exposure to LUM/IVA. Study assessments were performed at baseline and at 1, 3, 6, and 12 months after LUM/IVA initiation.Results: A total of 193 patients initiated LUM/IVA, and 85% completed the study through 1 year.
