Study summary

To assess the bioequivalence between lesinurad/allopurinol 200/300 FDC tablets and coadministered lesinurad and allopurinol tablets in the fasted state based on the pharmacokinetic (PK) evaluation of lesinurad and allopurinol in healthy adult subjects.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • ranging between 18.5 kg/m2 and 30 kg/m2.
  • Screening serum urate level is ≤ 7.0 mg/dL.

Exclusion criteria

Exclusion Criteria:

  • Asian subject who has a positive test for the HLA-B*5801 allele.
  • History or current diagnosis of kidney stones.
  • Estimated , as determined at Screening, of ≤ 80 mL/min calculated by the Cockcroft-Gault formula using ideal body weight.
  • Undergone major surgery within 3 months prior to Screening.
  • Donated blood within 4 weeks prior to Day 1 or experienced an event (other than blood donation) of significant blood loss (> 450 mL) within 12 weeks prior to Day 1 or has given a plasma donation within 4 weeks prior to Day 1.
  • Inadequate venous access or unsuitable veins for repeated venipuncture.
  • Received any strong or moderate enzyme-inducing drug or product within 2 months prior to Screening.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Creatinine clearance (CrCl)

How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.

What researchers measure

Primary outcomes

  1. Pharmacokinetics (PK) endpoints in terms of maximum observed concentration (Cmax) for lesinurad/allopurinol 200/300 FDC tablets relative to lesinurad and allopurinol monocomponent tablets

    Cmax is the maximum observed concentration of a drug after administration

    Time frame: Days 1, 8, 15 and 22

  2. PK endpoints in terms of area under the plasma concentration time curve from zero to the last quantifiable sampling timepoint (AUC last) for lesinurad/allopurinol 200/300 FDC tablets relative to lesinurad and allopurinol monocomponent tablets

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

    Time frame: Days 1, 8, 15 and 22

  3. PK endpoints in terms of area under the plasma concentration time curve from and from zero to infinity (AUC 0-∞) for lesinurad/allopurinol 200/300 FDC tablets relative to lesinurad and allopurinol monocomponent tablets

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

    Time frame: Days 1, 8, 15 and 22

  4. PK endpoints in terms of time of occurrence of maximum observed concentration (tmax) for lesinurad/allopurinol 200/300 FDC tablets relative to lesinurad and allopurinol monocomponent tablets

    Tmax is the time of occurrence of cmax

    Time frame: Days 1, 8, 15 and 22

  5. PK endpoints in terms of apparent terminal half-life (t1/2) for lesinurad/allopurinol 200/300 FDC tablets relative to lesinurad and allopurinol monocomponent tablets

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

    Time frame: Days 1, 8, 15 and 22

Secondary outcomes

  1. Incidence of Adverse Events in terms of changes in laboratory parameters

    Time frame: 26 days

  2. Incidence of Adverse Events in terms of electrocardiogram parameters

    Time frame: 26 days

  3. Incidence of Adverse Events in terms of vital signs

    Time frame: 26 days

  4. Incidence of Adverse Events in terms of physical examination findings

    Time frame: 26 days

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Aug 2017 to primary completion in Oct 2017, 1 month.

Of 37 industry-sponsored phase 1 interventional studies under Gout, half reached primary completion within 6 months of starting (the median), counting those still running; a quarter within 1 and three quarters within 14. This study's 1 month is below that.

Counting every sponsor, half of 40 studies reached it within 6 months; a quarter within 1 and three quarters within 14.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 7, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
