Popis opatření |
Časové okno |
|---|---|---|
|
Safety and Tolerability Based on Adverse Events (AEs)
Časové okno: Up to 14 days after last dose (last dose = Day 28)
|
AE: any untoward medical occurrence in a participant during the study; the event does not necessarily have a causal relationship with the treatment.
This includes any newly occurring event or previous condition that has increased in severity or frequency after the informed consent form is signed.
AE includes serious as well as Non-serious AEs.
Serious adverse event (SAE) (subset of AE): medical event or condition, which falls into any of the following categories, regardless of its relationship to the study drug: death, life threatening adverse experience, in-patient hospitalization/prolongation of hospitalization, persistent/significant disability or incapacity, congenital anomaly/birth defect, important medical event.
Number of participants with AEs and SAEs are reported.
An AE that started at or after initial dosing of study drug, or increased in severity after initial dosing of study drug visit is considered treatment-emergent.

Change From Baseline in Forced Expiratory Volume in 1 Second (FEV1) at Day 28
Časové okno: Baseline, Day 28
|
FEV1 is the volume of air that can forcibly be blown out in one second, after full inspiration.
|
Baseline, Day 28
|
|
Change From Baseline in Percent Predicted FEV1 at Day 28
Časové okno: Baseline, Day 28
|
FEV1 is the volume of air that can forcibly be blown out in one second, after full inspiration.
Predicted FEV1 (for age, gender, and height) was calculated using the Knudson method.
|
Baseline, Day 28
|
|
Change From Baseline in Forced Vital Capacity (FVC) at Day 28
Časové okno: Baseline, Day 28
|
FVC is the volume of air that can be forcibly exhaled from the lungs after taking the deepest breath possible.
|
Baseline, Day 28
|
|
Change From Baseline in Forced Expiratory Flow Over the Middle Half of the FVC (FEF25-75) at Day 28
Časové okno: Baseline, Day 28
|
FEF25-75 is total volume of air exhaled from the lungs over the middle half of the FVC test, expressed as liters per second (L/sec).
|
Baseline, Day 28
|
|
Change From Baseline in Sweat Chloride at Day 28
Časové okno: Baseline, Day 28
|
Sweat samples were collected using an approved Macroduct (Wescor) collection device.
A volume of greater than or equal to (>=) 15 microliter was required for determination of sweat chloride.
|
Baseline, Day 28
|
|
Change From Baseline in Nasal Potential Difference (NPD) of Zero Chloride Plus Isoproterenol Response at Day 28
Časové okno: Baseline, Day 28
|
Nasal potential difference (NPD) provides a direct and sensitive evaluation of sodium and chloride transport in secretory epithelial cells via assessment of transepithelial bioelectric properties. NPD under conditions of zero chloride concentration perfusion solution in the presence of isoproterenol is reported. NPDs were performed according to Cystic Fibrosis Foundation Therapeutics Development Network (CFFT TDN) Standard Operating Procedure (SOP) 528.00 "Standardization of Measurement of Nasal Membrane Transepithelial Potential Difference (NPD) - electronic data capture (EDC) and Perfusion or Perfusion-Free Probe". |
Baseline, Day 28
|
|
Change From Baseline in Cystic Fibrosis Questionnaire-Revised (CFQ-R) Domain Scores at Day 28
Časové okno: Baseline, Day 28
|
The CFQ-R is a validated participant-reported outcome measuring health-related quality of life for participants with cystic fibrosis.
CFQ-R domains include: Body, Digestion, Eat, Emotion, Health Perceptions, Physical, Respiratory, Role, Social, Treatment Burden, Vitality, and Weight.
Individual domain score range: 0-100; higher scores indicating fewer symptoms and better health-related quality of life.

|
Only participants who received VX-809 were analyzed for this outcome measure.
|
Day 1 (pre dose, 0.75, 1.5, 3, 4, 6, 9, 12, and 24 hours post-dose), Day 28 (pre dose, 0.75, 1.5, 3, 4, 6, 9, 12, 24, and 30-60 hours post dose)

|
Only participants who received VX-809 were analyzed for this outcome measure.
