What is being measured
The primary outcome is the main question the study is designed to answer.
Characteristics of AME in terms of pharmacokinetics (PK), metabolism, and excretion
PK profile in terms of AUC, Tmax, Cmax, t1/2, Ae, CLr, and CL/F.
AUC: area under the concentration-time curve; Tmax: time to reach maximum concentration; Cmax: maximum concentration; t1/2: apparent terminal half-life; Ae: amount of compound excreted in urine unchanged; CLr: renal clearance; CL/F: total body clearance corrected for bioavailability
Metabolic profile of RDEA3170 in plasma, urine, and feces.
Excretion in terms of recovery of radioactivity in urine and feces.
Measured: Day 1 predose, 15, 30, 45 mins, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 24, 30, 36, 48, 54, 60, 72 hrs postdose (blood and plasma only); Day 1, -12 to 0, 0-6, 6-12, 12-24 hrs postdose (urine and feces only)
Secondary outcomes (1)
Incidence of Adverse Events and Changes in Laboratory, Electrocardiogram, and Vital Signs Parameters
Measured: 5 weeks

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing RDEA3170 10 mg in people with Healthy, run by Ardea Biosciences, Inc. at 1 site in United States.
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 4 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 9 Jan 2014. 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 United States. 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?
Characteristics of AME in terms of pharmacokinetics (PK), metabolism, and excretion (time frame: Day 1 predose, 15, 30, 45 mins, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 24, 30, 36, 48, 54, 60, 72 hrs postdose (blood and plasma only); Day 1, -12 to 0, 0-6, 6-12, 12-24 hrs postdose (urine and feces only)). 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 9 Jan 2014.
