Effect of dotinurad in hyperuricemia with hypertension: a randomized study with febuxostat

Basic Information

Recruitment status	Recruiting
Health condition(s) or Problem(s) studied	Hyperuricemia complicated by hypertension
Date of first enrollment	28/03/2025
Target sample size	360
Countries of recruitment
Study type	Interventional
Intervention(s)	After determining eligibility of patients for whom consent is obtained, all patients who meet the eligibility criteria will be enrolled and randomized to one of two groups: dotinurad or febuxostat. However, patients who are using uric acid-lowering drugs at the time of obtaining consent will be withdrawn for at least 27 days before the start of study drug administration, after which eligibility will be determined and all patients who meet the eligibility criteria will be enrolled. In principle, a baseline (0-week) examination will be conducted within 70 days after obtaining consent, followed by 24 weeks of observation and examination. During the observation period, no changes or additions to the dosage or administration of drugs other than the study drug will be made in principle, but changes or additions will be permitted under the overall clinical judgment of the physician in charge according to the medical conditions of the study participants.

Outcome(s)

Primary Outcome

Changes in CAVI at 24 weeks after study drug administration

Secondary Outcome

1. change in CAVI category (<8.0: normal, 8.0 to 9.0: borderline, 9.0 or greater: abnormal) in the vascular insufficiency index at 24 weeks after treatment with study drug (key secondary endpoints) Change in CAVI at 12 weeks after treatment with study drug Change in CAVI category in the vascular insufficiency index (<8.0: normal, 8.0 to 9.0: borderline, 9.0 or greater: abnormal) at 12 weeks after treatment with study drug
