RATIONALE: Combination lumacaftor/ivacaftor has been shown to improve lung
function and other endpoints in patients aged 12 years and older with cystic
fibrosis and homozygous for F508del-CFTR, but it has not been assessed in younger
patients. OBJECTIVES: In this open-label phase III trial, we evaluated the
safety, tolerability, pharmacodynamics, and efficacy of lumacaftor/ivacaftor
combination therapy in patients aged 6-11 years with cystic fibrosis who were
homozygous for F508del-CFTR. METHODS: Patients (N?=?58) received 200 mg
lumacaftor/250 mg ivacaftor orally every 12 hours for 24 weeks in addition to
their existing cystic fibrosis medications. MEASUREMENTS AND MAIN RESULTS:
Lumacaftor/ivacaftor was well tolerated; the safety profile was generally similar
to that observed in larger lumacaftor/ivacaftor trials with older patients. Four
patients discontinued (two because of drug-related adverse events: elevated liver
transaminases, n?=?1; rash, n?=?1). No safety concerns were associated with
spirometry. No significant changes in percent predicted FEV(1) were observed
(change from baseline at Week 24, +2.5 percentage points; 95% confidence interval
[CI], -0.2 to 5.2; P?=?0.0671). At Week 24, significant improvements from
baseline were observed in sweat chloride (-24.8 mmol/L; 95% CI, -29.1 to -20.5;
P?0.0001), body mass index z score (+0.15; 95% CI, 0.08 to 0.22; P?0.0001),
Cystic Fibrosis Questionnaire-Revised respiratory domain score (+5.4; 95% CI, 1.4
to 9.4; P?=?0.0085), and lung clearance index based on lung volume turnover
required to reach 2.5% of starting N(2) concentration (-0.88; 95% CI, -1.40 to
-0.37; P?=?0.0018). CONCLUSIONS: Lumacaftor/ivacaftor was well tolerated in this
young population; no new safety concerns were identified. Improvements in lung
clearance index, sweat chloride, nutritional status, and health-related quality
of life were observed after 24 weeks of treatment. Clinical trial registered with
www.clinicaltrials.gov (NCT01897233).
