PROTOCOL OUTLINE:
This is a randomized, dose escalation, double blind, placebo controlled, multicenter study. Patients are randomized to receive either adeno-associated virus-CFTR (AAV-CFTR) vector or placebo.
Patients undergo tests on days -10 to -4 to rule out adenovirus and adeno-associated virus infections. Patients then receive AAV-CFTR vector intranasally to the right or left inferior turbinates and placebo to the other side of the nose. The next day, patients receive an endobronchial dose of AAV-CFTR vector to the superior segment of the right lower lobe.
Cohorts of 2-4 patients each receive escalating doses of AAV-CFTR vector until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose level immediately preceding the dose at which at least 2 subjects develop dose limiting toxicity.
Patients are followed at day 10, then at 1, 2, 3, 6, 9, and 12 months.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Adeno-associated virus-CFTR vector in people with Cystic Fibrosis, run by National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
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 1 Jun 2017. Status can change between updates, so confirm with the study contact before making plans.
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.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00004533, which also lists 1 linked publication.
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 1 Jun 2017.
