  2. Time of Occurrence of Maximum Observed Concentration (Tmax)

    Tmax is the time of occurrence of cmax

    Measured: Day 1, 5, 9, 13, 17

  3. Area Under the Concentration-time Curve From Time Zero to the Quantifiable Last Sampling Timepoint (AUC Last)

    AUC last is the area under the plasma concentration time curve from zero to the last quantifiable sampling timepoint

    Measured: Day 1, 5, 9, 13, 17

  4. Area Under the Concentration-time Curve From 0 to Infinity (AUC∞)

    AUC 0-∞ is a meausre of total concentration from time zero to infinity

    Measured: Day 1, 5, 9, 13, 17

  5. Apparent Terminal Half-life (t1/2)

    t1/2 is a measure of apparent terminal half-life

    Measured: Day 1, 5, 9, 13, 17

  6. Maximum Observed Plasma Concentration (Cmax): Effect of High Fat Meal on the PK of RDEA3170 Capsules

    Cmax is the maximum observed concentration of a drug after administration

    Measured: Day 1, 5, 9, 13, 17

  7. AUC Last: Effect of High Fat Meal on the PK of RDEA3170 Capsules

    AUC last is the area under the plasma concentration time curve from zero to the last quantifiable sampling timepoint

    Measured: Day 1, 5, 9, 13, 17

  8. AUC∞: Effect of High Fat Meal on the PK of RDEA3170 Capsules

    AUC 0-∞ is a meausre of total concentration from time zero to infinity

    Measured: Day 1, 5, 9, 13, 17

Secondary outcomes (2)
  1. Pharmacodynamics (PD) Profile of RDEA3170

    Serum samples were collected at the following timepoints in relation to RDEA3170 dosing: Day 1 (Cohort 1 and Cohort 3): -24, -23, -22, -21, -20, -18, -16, -14, and -12 hours prior to dosing. Days 1, 5, and 9 (Cohort 1 and Cohort 3), and Days 13 and 17 (Cohort 1 only): predose (within 30 minutes prior to dosing) and 1, 2, 3, 4, 6, 8, 10, 12, and 24 hours postdose. Urine samples (total catch) were collected at the following timepoints in relation to RDEA3170 dosing: Day 1 (Cohort 1 and Cohort 3): -24 to -21, -21 to -18, -18 to -12, and -12 to 0 hours predose. Days 1, 5, and 9 (Cohort 1 and Cohort 3), and Days 13 and 17 (Cohort 1 only): 0 to 3, 3 to 6, 6 to 12, and 12 to 24 hours postdose.

    Measured: Day -1, 1, 5, 9, 13, 17

  2. Incidence of Treatment-Emergent Adverse Events

    Measured: 8 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing RDEA3170,10 mg, RDEA3170, 2.5 mg and RDEA3170, 5 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 11 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 20 Aug 2018. 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?

Yes. Results are posted in the registry (first posted 20 Aug 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Maximum Observed Plasma Concentration (Cmax) (time frame: Day 1, 5, 9, 13, 17). The study lists 8 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 20 Aug 2018.
