Descrizione dettagliata
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.

Cosa sta misurando lo studio?
Misure di risultato primarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Absolute Mean Change From Baseline in Percent Predicted Forced Expiratory Volume in 1 Second (FEV1) Through Week 24
Lasso di tempo: baseline through 24 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 24 weeks
|
Misure di risultato secondarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Variazione assoluta rispetto al basale della concentrazione di cloruro nel sudore fino alla settimana 24 e alla settimana 48
Lasso di tempo: basale attraverso 24 settimane e 48 settimane
|
Il test del cloruro nel sudore (ionoforesi quantitativa della pilocarpina) è uno strumento diagnostico standard per la fibrosi cistica (CF), che funge da indicatore dell'attività del regolatore della conduttanza transmembrana della fibrosi cistica (CFTR).
|
basale attraverso 24 settimane e 48 settimane
|
|
Variazione assoluta del peso rispetto al basale alla settimana 24 e alla settimana 48
Lasso di tempo: basale a 24 settimane e 48 settimane
|
Poiché la malnutrizione è comune nei pazienti con fibrosi cistica (FC) a causa dell'aumento del dispendio energetico dovuto a malattie polmonari e malassorbimento dei grassi, il peso corporeo è un'importante misura clinica dello stato nutrizionale.
|
basale a 24 settimane e 48 settimane
|
|
Absolute Mean Change From Baseline in Percent Predicted FEV1 Through Week 48
Lasso di tempo: 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)
Lasso di tempo: 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
Lasso di tempo: 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.
