About this study
Official title: A Phase 1, Randomized, Open-Label, Drug-Drug Interaction Study to Evaluate the Potential Pharmacokinetic and Pharmacodynamic Interaction Between Lesinurad and Calcium Carbonate and Aluminum/Magnesium Hydroxide-Containing Antacids in Healthy Adult Male Subjects
This study will assess the potential effects of calcium carbonate and aluminum/magnesium hydroxide-containing antacids on the pharmacokinetics (PK) and pharmacodynamics (PD) of lesinurad in healthy, adult male subjects.
Read the detailed description
In this study, lesinurad and antacid will be administered in the fed state, antacid doses will be attenuated to reflect the more commonly used doses, baseline PD assessments will be performed both in presence and absence of antacid treatment, and the sequence of treatments (lesinurad +/- antacid) will be randomized.
- Conditions
- Healthy
- Being tested
- Lesinurad 400 mg, Tums 500 mg and 750 mg, MINTOX 10 mL

What is being measured
The primary outcome is the main question the study is designed to answer.
PK profile of lesinurad from plasma and urine
Plasma in terms of maximum observed concentration (Cmax), time of occurrence of maximum observed concentration (Tmax), area under the concentration-time curve (AUC), apparent terminal half-life (t½), renal clearance (CLR), and adverse event (Ae).
Measured: Day 2 and Day 7
PD profile of Lesinurad from serum and urine
Serum PD in terms of serum urate concentration, urine uric acid excretion amount, renal clearance of uric acid, and fractional excretion of uric acid.
Measured: Day 2 and Day 7
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 Lesinurad 400 mg, Tums 500 mg and 750 mg and MINTOX 10 mL 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 2 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 20 May 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?
PK profile of lesinurad from plasma and urine (time frame: Day 2 and Day 7). The study lists 2 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 May 2014.
