What is being measured
The primary outcome is the main question the study is designed to answer.
To determine the absolute bioavailability of mannitol powder for inhalation by comparison to mannitol administered intravenously.
To determine the relative bioavailability of mannitol powder for inhalation by comparison to orally administered mannitol.
To determine the pharmacokinetic parameters of systemically available mannitol after administration of mannitol powder by inhalation.
Secondary outcomes (1)
A secondary objective of the study is to provide information on the urinary excretion of mannitol after each of the routes of administration.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Mannitol in people with Healthy Volunteers, run by Syntara.
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 13 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 13 Mar 2007. 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.
What does the primary outcome measure?
To determine the absolute bioavailability of mannitol powder for inhalation by comparison to mannitol administered intravenously.. The study lists 3 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 13 Mar 2007.
