Last updated: July 22, 2016
Last verified: May 2016
  Purpose
This is a Phase 3, 2-part (Part A and Part B), open-label, multicenter study evaluating the pharmacokinetics (PK), safety, tolerability, and pharmacodynamics (PD) of multiple doses of Lumacaftor/Ivacaftor (LUM/IVA) in subjects 2 through 5 years of age (inclusive) with Cystic Fibrosis (CF), homozygous for F508del. Subjects who participate in Part A may participate in Part B, if patient meet the eligibility criteria.

Primary Outcome Measures:
  • Part A: Pharmacokinetic (PK) parameters of lumacaftor (LUM) and ivacaftor (IVA): estimated peak concentrations (Cmax) [ Time Frame: up to 15 Days ]
  • Part A: Pharmacokinetic (PK) parameters of lumacaftor (LUM) and ivacaftor (IVA): estimated trough concentrations (Ctrough) [ Time Frame: up to 15 Days ]
  • Part B: Safety and Tolerability assessments as determined by number of subjects with adverse events (AEs) and serious adverse events (SAEs) [ Time Frame: Baseline up to 28 days after last dose (up to 28 weeks) ]

Secondary Outcome Measures:
  • Part A: PK parameters of LUM and IVA metabolites: estimated peak concentrations (Cmax) of lumacaftor and ivacaftor metabolites [ Time Frame: up to 15 days ]
  • Part A: PK parameters of LUM and IVA metabolites: estimated trough concentrations (Ctrough) of lumacaftor and ivacaftor metabolites [ Time Frame: up to 15 days ]
  • Part A: Safety and Tolerability assessments as determined by number of subjects with adverse events (AEs) and serious adverse events (SAEs) [ Time Frame: Baseline up to 10 +/- 3 days after the last dose (up to 25 +/- 3 days) ]
  • Part B: Absolute change from baseline in sweat chloride level [ Time Frame: Baseline, Week 24 ]
  • Part B: Absolute change from baseline in body mass index (BMI) and BMI for age z score [ Time Frame: Baseline, Week 24 ]
  • Part B: Absolute change from baseline in weight and weight for age z score [ Time Frame: Baseline, Week 24 ]
  • Part B: Absolute change from baseline in stature and stature for age z score [ Time Frame: Baseline, Week 24 ]
  • Part B: Absolute change from baseline in lung clearance index (LCI)2.5 [ Time Frame: Baseline, Week 24 ]
  • Part B: Absolute change from baseline in LCI5.0 [ Time Frame: Baseline, Week 24 ]
  • Part B: Time-to-first pulmonary exacerbation [ Time Frame: through Week 24 ]
  • Part B: Number of pulmonary exacerbations [ Time Frame: through Week 24 ]
  • Part B: Number of CF-related hospitalizations [ Time Frame: through Week 24 ]
  • Part B; Absolute change from Baseline in fecal elastase-1 (FE-1) levels [ Time Frame: Baseline, Week 24 ]
  • Part B: Absolute change in serum levels of immunoreactive trypsinogen (IRT) [ Time Frame: from baseline through Week 24 ]
  • Part B: Changes in sputum microbiology cultures [ Time Frame: from baseline through Week 24 ]
  • Part B: Absolute change from baseline in percent predicted forced expiratory volume in 1 second (ppFEV1) [ Time Frame: Baseline, Week 24 ]
  • Part B: Acceptability/palatability of LUM/IVA granules measured using hedonic scale [ Time Frame: Day 1 ]
  • Part B: PK parameters of LUM, IVA, and their respective metabolites: estimated trough concentrations (Ctrough) of LUM and IVA and their metabolites [ Time Frame: up to 24 weeks ]
