Gedetailleerde beschrijving
This was a phase 3 study in subjects with cystic fibrosis (CF) age 12 years and older who have a G551D-CFTR mutation and percent predicted forced expiratory volumn in 1 second (FEV1) between 40% and 90%.
Based on in vitro studies and pharmacologic, pharmacokinetic (PK), and safety profiles, ivacaftor was selected for clinical development as a possible treatment for patients with CF. Patients with the G551D mutation were the targeted population for this study because ivacaftor is a potentiator of the gating function of the CFTR protein, and the most prevalent mutation with a gating defect in CF is the G551D mutation.
This study was designed to further evaluate the efficacy of ivacaftor in subjects with CF who have a G551D-CFTR gene mutation and to evaluate safety in this population over a longer period than previously studied.

Tijdsspanne |
|---|---|---|
|
Absolute verandering vanaf baseline in zweetchlorideconcentratie tot en met week 24 en week 48
Tijdsspanne: baseline tot en met 24 weken en 48 weken
|
De zweetchloride-test (kwantitatieve pilocarpine-iontoforese) is een standaard diagnostisch hulpmiddel voor cystic fibrosis (CF) en dient als een indicator van cystic fibrosis transmembrane conductance regulator (CFTR)-activiteit.
|
baseline tot en met 24 weken en 48 weken
|
|
Absolute verandering ten opzichte van de uitgangswaarde in gewicht in week 24 en week 48
Tijdsspanne: baseline tot 24 weken en 48 weken
|
Aangezien ondervoeding veel voorkomt bij patiënten met cystische fibrose (CF) vanwege een verhoogd energieverbruik als gevolg van longziekte en slechte vetopname, is het lichaamsgewicht een belangrijke klinische maatstaf voor de voedingsstatus.
|
baseline tot 24 weken en 48 weken
|
|
Absolute Mean Change From Baseline in Percent Predicted FEV1 Through Week 48
Tijdsspanne: baseline through 48 weeks
|
Spirometry (as measured by FEV1) is a standardized assessment to evaluate lung function that is the most widely used endpoint in cystic fibrosis studies.
|
baseline through 48 weeks
|
|
Absolute Change From Baseline in Cystic Fibrosis Questionnaire-Revised (CFQ-R) Score Through Week 24 and Week 48 (Respiratory Domain Score, Pooled)
Tijdsspanne: baseline through 24 weeks and 48 weeks
|
The CFQ-R is a health-related quality of life measure for subjects with cystic fibrosis.
Each domain is scored from 0 (worst) to 100 (best).
A difference of at least 4 points in the respiratory domain score of the CFQ-R is considered a minimal clinically important difference (MCID).
|
baseline through 24 weeks and 48 weeks
|
|
Time-to-first Pulmonary Exacerbation Through Week 24 and Week 48
Tijdsspanne: baseline through 24 weeks and 48 weeks
|
Pulmonary exacerbation was defined as a change in antibiotic therapy (intravenous, inhaled, or oral) for any 4 or more of signs/symptoms such as change in sputum; new or increased hemoptysis; increased cough or dyspnea; malaise, fatigue, or lethargy; temperature above 38 degrees C; anorexia or weight loss; sinus pain/tenderness and discharge; change in physical examination of the chest; decreased pulmonary function by 10%; and radiographic changes indicative of pulmonary infection.
