COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted/resubmitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Drugs - Verinurad
Treatment: Drugs - Allopurinol
Treatment: Drugs - Placebo for verinurad
Treatment: Drugs - Placebo for allopurinol

Experimental: Verinurad + allopurinol - Dose [mg] verinurad/allopurinol: Step 1 - titration_3/100 Step 2 - titration_7.5/200 Step 2 - target dose_12/300

Experimental: Allopurinol alone - Dose [mg] verinurad/allopurinol:

Drug: Allopurinol The treatment will be titrated in 3 steps. Low dose (100mg), intermediate (200mg) and high dose (300mg) of allopurinol.

Treatment: Drugs: Allopurinol
Study treatments will be titrated in 3 steps: Low dose (100mg), intermadiate (200mg) and high dose (300mg) of allopurinol

Outcomes
Primary outcome [1] 0 0
Change from baseline at Week 32 in peak V02 - To assess effect of verinurad + allopurinol compared to placebo or allopurinol monotherapy on exercise capacity.
Timepoint [1] 0 0
From baseline at Week 32
Secondary outcome [1] 0 0
Change from baseline at Week 32 in Kansas-City Cardiomyopathy Questionnaire-Total Symptom Score (KCCQ-TSS) - To assess effect of verinurad + allopurinol compared to placebo or allopurinol monotherapy on Kansas-City Cardiomyopathy Questionnaire-Total Symptom Score (KCCQ-TSS). The score ranges from 0 to 100, where a higher score represents a better patient outcome.
Timepoint [1] 0 0
From baseline at Week 32

Eligibility
Key inclusion criteria
- Patient must be = 40 years of age at the time of signing the ICF

- Patients with hyperuricaemia defined as sUA level of > 6 mg/dL.

- Patients with documented diagnosis of symptomatic HFpEF according to all of the
following criteria:

1. Have NYHA functional class II-III at enrolment

2. Have medical history of typical symptoms/signs of HF > 6 weeks before enrolment

3. LVEF = 45%

4. NT-proBNP = 125 pg/mL (= 14.75 pmol/L) at Visit 2 for patients without ongoing
atrial fibrillation/flutter.

- Patients able to exercise to near exhaustion during a CPET as exhibited by RER

= 1.05 during CPET conducted during screening. If patient does not achieve RER = 1.05
the CPET may be repeated once, at least 48 hours but less than 2 weeks (but before
randomisation) after the initial test; in such cases the second test will serve as
baseline.

- Male or female
Minimum age
40 Years
Maximum age
130 Years
Gender
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
- eGFR < 30ml/min/1.73m2 (based on CKD-EPI formula)

- Presence of any condition that precludes exercise testing

- Known history of a documented LVEF < 40%

- Probable alternative or concomitant diagnoses which in the opinion of the Investigator
could account for the patient's HF symptoms and signs (eg, anaemia, hypothyroidism)

- Known carrier of the Human Leukocyte Antigen-B (HLA-B) *58:01 allele: HLA-B

*58:01 genotyping is mandatory prior to randomization for all patients.

- Patients diagnosed with tumor lysis syndrome or Lesch-Nyhan syndrome

- Patients who are severely physically or mentally incapacitated and who in the opinion
of investigator are unable to perform the patients' tasks associated with the protocol

- Presence of any condition which, in the opinion of the investigator, places the
patient at undue risk or potentially jeopardises the quality of the data to be
generated

- Current acute decompensated HF or hospitalisation due to decompensated HF < 4 weeks
prior to enrolment

- Myocardial infarction, unstable angina, coronary revascularisation (percutaneous
coronary intervention or coronary artery bypass grafting), ablation of atrial
flutter/fibrillation, valve repair/replacement, implantation of a cardiac
resynchronisation therapy device, stroke or transient ischemic attack within 6 months
prior to enrolment.

- Planned coronary revascularisation, ablation of atrial flutter/fibrillation and/or
valve repair/replacement

- Atrial fibrillation with persistent resting heart rate > 110 beats per minute.
