About this study
Official title: A Randomized, Double-Blind, Placebo-Controlled, Multiple-Dose, Drug-Drug Interaction Study of VX-809 and VX-770 in Healthy Subjects
The purpose of this study is to assess the pharmacokinetics and safety of co-administration of VX-770 and VX-809 in healthy adults.
Read the detailed description
Cystic fibrosis (CF) is an inherited disease resulting from defects to a gene known as the cystic fibrosis transmembrane conductance regulator (CFTR). CF affects approximately 70,000 children and adults worldwide (30,000 in the United States) and is the most common fatal genetic disease in persons of European descent. Despite progress in the treatment of CF with antibiotics and mucolytics, the predicted median age of survival for a person with CF is in the mid-30s. Though the disease affects multiple organs, most morbidity and mortality is caused by progressive loss of lung function.
This is a Phase 1, randomized, double-blind, placebo-controlled, multiple-dose study of orally administered VX-809 and VX-770 in healthy subjects. The study will evaluate safety and tolerability of co-administration of VX-809 and VX-770 in healthy volunteers.
Enrollment is planned for 24 subjects at 1 clinical site. Subjects will be randomized to receive study drug or placebo during three 14-day treatment periods separated by 14-day washout periods. In Treatment Period 1, subjects randomized to study drug will receive VX-809 every 24 hours. In Treatment Period 2, subjects randomized to study drug will receive VX-770 every 12 hours. In Treatment Period 3, subjects randomized to study drug will receive VX-809 every 24 hours and VX-770 every 12 hours. Subjects randomized to placebo will receive placebo during all treatment periods.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing VX-809, VX-770 and VX-809 & VX-770 in people with Cystic Fibrosis, run by Vertex Pharmaceuticals Incorporated at 1 site in Netherlands.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 5 Jan 2010. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Netherlands. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Pharmacokinetic (PK) parameters of VX-770 and its metabolites in plasma in the presence and absence of VX-809 (time frame: 70 days). 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 5 Jan 2010; AzTrials last refreshed its copy on 7 Nov 2026.
