About this study
Official title: A Phase 4, Study to Evaluate the Safety and Efficacy of Lesinurad 200 mg in Combination With a Xanthine Oxidase Inhibitor (XOI), Compared With an XOI Alone, in Subjects With Gout and Estimated Creatinine Clearance (eCrCl) 30 to <60 mL/Min Who Have Not Achieved Target Serum Uric Acid Levels (sUA) on an XOI Alone
This study evaluates the safety and efficacy of lesinurad administered with an XOI versus a placebo plus an XOI in gout participants who have moderate renal impairment and who are not at target level of serum urate (sUA).
Read the detailed description
This postmarketing study is a randomized, double-blind, placebo-controlled study to evaluate safety (with particular focus on renal and cardiovascular events) and efficacy of lesinurad 200 mg once daily (QD) in combination with an XOI for up to 24 months compared with XOI monotherapy, in participants with gout and moderate renal impairment who have not reached target sUA levels (<6.0 mg/dL) on an XOI alone.
- Conditions
- Gout, Chronic Kidney Disease (CKD)
- Being tested
- Lesinurad, XOI, Placebo, colchicine, corticosteroids
- Medical subject headings
- Gout, Renal Insufficiency, Chronic
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
LesinuradDrug
Also called RDEA594
200 mg oral tablet
XOIDrug
Also called allopurinol, febuxostat
All participants must be on a stable, medically appropriate dose of XOI as their sole urate-lowering therapy (ULT) indicated for the treatment of gout for at least 4 weeks prior to Screening and throughout the Screening Period. This stable dose of XOI will be maintained throughout the study period.
PlaceboDrug
matching placebo oral tablet
colchicineDrug
Gout flare prophylaxis: commercially available colchicine is provided through the Month 6 study visit. Actual colchicine dose (0.5 or 0.6 mg qd) and frequency were adjusted based on the local label, subject medical history, and clinical judgement.
corticosteroidsDrug
Gout flare prophylaxis: Participants unable to take colchicine are permitted to take a short course of low-dose oral corticosteroids up to the Month 3 study visit
| Study group | Role | What they receive |
|---|---|---|
| Lesinurad + XOI | Active comparator | lesinurad 200 mg oral tablet QD plus a stable, medically appropriate dose of an XOI Receives: Drug: Lesinurad; Drug: XOI; Drug: colchicine; Drug: corticosteroids |
| Placebo + XOI | Placebo comparator | placebo tablet QD plus a stable, medically appropriate dose of an XOI Receives: Drug: XOI; Drug: Placebo; Drug: colchicine; Drug: corticosteroids |

Percentage of Participants Meeting Criteria (eg, Based on sCr or eCrCl Criteria) for Treatment Discontinuations Over the Study Period
Kidney function was monitored throughout the study by measuring sCr and calculating eCrCl by Cockcroft-Gault formula using ideal body weight.

Measured: up to 18 months
Percentage of Participants Renal-Related and Kidney Stone Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)
Renal-related and kidney stone events were based on Medical Dictionary for Regulatory Activities (MedDRA) "Renal and Urinary Disorders" system organ classification. AEs that started on or after the first dose of study drug in this study, or those AEs with onset prior to the first dose of study drug but worsened after the first dose of study drug, were considered treatment emergent.
Measured: From first dose of study drug through each participant's study duration, up to approximately 18 months.
Percentage of Participants With Contributing Factors to Renal SAEs as Adjudicated by the Renal Event Adjudication Committee (REAC)
Measured: From first dose of study drug through each participant's study duration, up to approximately 18 months.
Percentage of Participants With Cardiac Event Adjudication Committee (CEAC)-Adjudicated Major Adverse Cardiovascular Events (MACEs)
MACEs are defined as Cardiovascular Death, Nonfatal Myocardial Infarction, and Nonfatal Stroke.
Measured: From first dose of study drug through each participant's study duration, up to approximately 18 months.
Incidence of CEAC-Adjudicated MACEs or Hospitalization for Unstable Angina (MACE+)
MACEs are defined as Cardiovascular Death, Nonfatal Myocardial Infarction, and Nonfatal Stroke.
Measured: From first dose of study drug through each participant's study duration, up to approximately 18 months.

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 9 inclusion and 20 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: stopped early, as of the sponsor's last update on 4 Nov 2021. 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. Some participants in this study may receive a placebo. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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 4 Nov 2021). 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?
Percentage of Participants Who Achieve Serum Urate (sUA) < 6.0 mg/dL at Month 6 (time frame: Month 6). 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 4 Nov 2021.
