About this study

Official title: A Phase 3, Two-Part, Randomized, Double-Blind, Placebo-Controlled, Crossover Study With an Open-Label Period to Evaluate the Efficacy and Safety of Ivacaftor in Subjects With Cystic Fibrosis Who Have a Non-G551D CFTR Gating Mutation

The purpose of this study is to evaluate the efficacy and safety of ivacaftor in subjects with cystic fibrosis (CF) who have a non-G551D cystic fibrosis transmembrane regulator (CFTR) gating mutation (any one of the following CFTR mutations: G178R, G551S, S549N, S549R, G970R, G1244E, S1251N, S1255P, or G1349D).

Read the detailed description

Ivacaftor is the first CFTR modulator to show an improvement in CFTR function and clinical benefit in subjects with CF. Results from Phase 3 studies (VX08-770-102 [Study 102] [NCT00909532] and VX08-770-103 [Study 103] [NCT00909727]) showed that ivacaftor is effective in the treatment of subjects with CF who have the G551D-CFTR mutation, as evidenced by sustained improvements in CFTR channel function (measured by reduction in sweat chloride concentration) and corresponding substantial, durable improvements in lung function, pulmonary exacerbations, respiratory symptoms, and weight gain. Ivacaftor was also well tolerated, as evidenced by the rates and reasons for premature discontinuation and results of safety assessments.

Ivacaftor (Trade Name Kalydeco; 150 mg tablets) was initially approved in the United States for the treatment of CF in subjects 6 years of age and older who have a G551D mutation in the CFTR gene.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Part 1: Absolute Change From Baseline in Percent Predicted Forced Expiratory Volume in 1 Second (FEV1) Through Week 8

    FEV1 is the volume of air that can forcibly be blown out in one second, after full inspiration. Hankinson and Wang standards were used to calculate percent predicted FEV1 (for age, gender, and height). The Hankinson standard was used for male subjects 18 years and older and female subjects 16 years and older. The Wang standard was used for male subjects aged 6 to 17 years and for female subjects aged 6 to 15 years. Baseline was defined as the most recent non-missing measurement collected before initial administration of study drug during study Part 1.

    Measured: Part 1: Baseline (pre-dose Day 1), Week 8

  2. Part 2: Absolute Change From Baseline in Percent Predicted Forced Expiratory Volume in 1 Second (FEV1) Through 24 Weeks of Treatment (Week 36 Visit)

    FEV1 is the volume of air that can forcibly be blown out in one second, after full inspiration. Hankinson and Wang standards were used to calculate percent predicted FEV1 (for age, gender, and height). The Hankinson standard was used for male subjects 18 years and older and female subjects 16 years and older. The Wang standard was used for male subjects aged 6 to 17 years and for female subjects aged 6 to 15 years. Absolute change in percent predicted FEV1 over 24 weeks of ivacaftor treatment (from Week 12 [Part 1: Treatment Period 2] through Week 36 [Part 2]) was reported for subjects who received ivacaftor in Part 1: Treatment Period 2, as per planned analysis. Baseline was defined as the most recent non-missing measurement collected before initial administration of study drug during Part 1: Treatment Period 2.

    Measured: Baseline (pre-dose Week 12), Week 36

Secondary outcomes (8)
  1. Part 1: Change From Baseline in Body Mass Index (BMI) at Week 8

    BMI was defined as weight in kilogram (kg) divided by height in meters^2 (m^2). Baseline was defined as the most recent non-missing measurement collected before initial administration of study drug during study Part 1.

    Measured: Part 1: Baseline (pre-dose Day 1), Week 8

  2. Part 2: Change From Baseline in Body Mass Index (BMI) at 24 Weeks of Treatment (Week 36 Visit)

    BMI was defined as weight in kg divided by height in m^2. Change in BMI over 24 weeks of ivacaftor treatment (from Week 12 [Part 1: Treatment Period 2] through Week 36 [Part 2]) was reported for subjects who received ivacaftor in Part 1: Treatment Period 2 as per planned analysis. Baseline was defined as the most recent non-missing measurement collected before initial administration of study drug during Part 1: Treatment Period 2.

    Measured: Baseline (pre-dose Week 12), Week 36

  3. Part 1: Change From Baseline in Sweat Chloride Through Week 8

    Sweat samples were collected using an approved Macroduct (Wescor, Logan, Utah) collection device. A volume of greater than or equal to (>=) 15 microliter was required for determination of sweat chloride. Baseline was defined as the most recent non-missing measurement collected before initial administration of study drug during study Part 1.

    Measured: Part 1: Baseline (pre-dose Day 1), Week 8

  4. Part 2: Change From Baseline in Sweat Chloride Through 24 Weeks of Treatment (Week 36 Visit)

    Sweat samples were collected using an approved Macroduct (Wescor, Logan, Utah) collection device. A volume of greater than or equal to (>=) 15 microliter was required for determination of sweat chloride. Change in sweat chloride over 24 weeks of ivacaftor treatment (from Week 12 [Part 1: Treatment Period 2] through Week 36 [Part 2]) was reported for subjects who received ivacaftor in Part 1: Treatment Period 2 as per planned analysis. Baseline was defined as the most recent non-missing measurement collected before initial administration of study drug during Part 1: Treatment Period 2.

    Measured: Baseline (pre-dose Week 12), Week 36

  5. Part 1: Change From Baseline in Cystic Fibrosis Questionnaire-Revised (CFQ-R) Respiratory Domain Score Through Week 8

    The CFQ-R is a validated patient-reported outcome measuring health-related quality of life for subjects with cystic fibrosis. Respiratory domain assessed respiratory symptoms (for example, coughing, congestion, wheezing), score range: 0-100; higher scores indicating fewer symptoms and better health-related quality of life. Baseline was defined as the most recent non-missing measurement collected before initial administration of study drug during study Part 1.

    Measured: Part 1: Baseline (pre-dose Day 1), Week 8

  6. Part 2: Change From Baseline in Cystic Fibrosis Questionnaire-Revised (CFQ-R) Respiratory Domain Score Through 24 Weeks of Treatment (Week 36 Visit)

    The CFQ-R is a validated patient-reported outcome measuring health-related quality of life for subjects with cystic fibrosis. Respiratory domain assessed respiratory symptoms (for example, coughing, congestion, wheezing), score range: 0-100; higher scores indicating fewer symptoms and better health-related quality of life. Change in CFQ-R respiratory domain score over 24 weeks of ivacaftor treatment (from Week 12 [Part 1: Treatment Period 2] through Week 36 [Part 2]) was reported for subjects who received ivacaftor in Part 1: Treatment Period 2 as per planned analysis. Baseline was defined as the most recent non-missing measurement collected before initial administration of study drug during Part 1: Treatment Period 2.

    Measured: Baseline (pre-dose Week 12), Week 36

The record lists 12 sites in United States, France, Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 29 Oct 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Part 1: Absolute Change From Baseline in Percent Predicted Forced Expiratory Volume in 1 Second (FEV1) Through Week 8 (time frame: Part 1: Baseline (pre-dose Day 1), Week 8). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Oct 2014.
