Recruitment & Eligibility
- Status
- Authorised-recruitment may be ongoing or finished
- Sex
- All
- Target Recruitment
- 861
- Provision of signed and dated, written ICF.
- Provision of signed and dated written genetic informed consent prior to collection of sample for genetic analysis
- Patient must be =18 years of age at the time of signing the ICF.
- Patients with CKD. CKD as defined in the Kidney Disease: Improving Global Outcomes (KDIGO) guidelinesas abnormalities in kidney structure or function present for >3 months; ie, there must be a documented occurrence at least 3 months before randomisation of either of the following eGFR <60 mL/min/1.73 m2, UACR =30 mg/g, and/or one or more other markers of kidney damage (including abnormalities detected by histology or imaging, urine sediments, urine protein dipstick =1+, positive urine albumin dipstick, or urinary protein to creatinine ratio =84 mg/g)
- Patients should receive background standard of care treatment for albuminuria and/or T2DM and be treated according to locally recognised guidelines, as appropriate. Guideline-recommended medications should be used at recommended doses. Therapy should have been optimised and stable for =4 weeks before study entry and include an ACEi or an ARB, unless contraindicated, not tolerated, or in the opinion of the investigator not practically available or suitable.
- If treated with a sodium-glucose transport protein (SGLT2) inhibitor, the SGLT2 inhibitor dose must have been stable for =4 weeks before randomisation.
- Meeting screening criteria for sUA and eGFR (Visit 2)
(a)sUA =6.0 mg/dL
(b)eGFR =25 mL/min/1.73 m2 (CKD-EPI formula)
- Mean UACR between 30 mg/g and 5000 mg/g inclusive. At least 2 first morning void samples collected before randomisation will be required.
- Male or female
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 358
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range 503
- Autosomal dominant or autosomal recessive polycystic kidney disease, lupus nephritis or anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (granulomatosis with polyangiitis [Wegener's granulomatosis], microscopic polyangiitis, or eosinophilic granulomatosis with polyangiitis [Churg-Strauss syndrome]).
- History of renal transplantation
- Known carrier of the (HLA-B) *58:01 allele. HLA-B *58:01 genotyping is mandatory prior to randomisation for all patients.
- Patients diagnosed with tumor lysis syndrome or Lesch-Nyhan syndrome
- History of stroke, myocardial infarction, percutaneous coronary intervention, coronary artery bypass graft in the past 6 months
- Uncontrolled hypertension presenting with systolic blood pressure >180 mm Hg and/or diastolic blood pressure >100 mm Hg
- Diagnosed with heart failure and (NYHA) Class IV at the time of randomisation
- QT interval corrected by the Fridericia formula (QTcF) >470 msec; patients diagnosed with long QT syndrome; patients with a family history of long QT syndrome
- Evidence of significant liver disease (eg, aspartate transaminase [AST] or alanine transaminase [ALT] >3x the upper limit of normal [ULN]; or total bilirubin >1.5x ULN). An isolated increase in bilirubin in patients with known Gilbert's syndrome is not a reason for exclusion.
- Receiving cytotoxic therapy, immunosuppressive therapy or other immunotherapy for primary or secondary renal disease within 6 months prior to enrolment
- Treated with any drug for hyperuricaemia in the 6 months preceding randomisation.
- Dose of ACEi, ARBs, fenofibrate, guaifenesin, or SGLT2 inhibitors changed within 4 weeks of randomisation or further dose titration expected after randomisation
- Treated with strong or moderate (OATP) inibitors
- Participation in another clinical study with an investigational product administered during the last month prior to randomisation
- Patients who are pregnant, lactating, or planning to become pregnant.
