OBJECTIVES: I. Evaluate the safety of ascending doses of CPX administered to adult patients with mild cystic fibrosis.
II. Evaluate the pharmacokinetics of ascending doses of CPX in this patient population.
Read the detailed description
PROTOCOL OUTLINE: This is a randomized, double blind, placebo controlled, dose escalation study.
There are 7 experimental cohorts, each treated with a different oral dose of CPX or placebo. Within each cohort, 4 patients receive a single dose of CPX and 1 patient receives placebo. Each patient is monitored 24 hours postdose. Escalation to the next dose level for each subsequent cohort begins only after the safety data obtained from the previous cohort is reviewed and found not to limit dose escalation.
All patients return for a follow up evaluation 1 week after dosing.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing CPX in people with Cystic Fibrosis, run by FDA Office of Orphan Products Development.
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 25 Mar 2015. 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 NCT00004428, which also lists 2 linked publications.
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 25 Mar 2015.
