Background: Dotinurad, a novel selective urate reabsorption inhibitor (SURI) that has a future potential for the treatment of hyperuricemia, reduces serum uric acid levels by selectively inhibiting urate transporter 1 (URAT1). We evaluated the efficacy and safety of dotinurad in hyperuricemic Japanese patients with or without gout. Methods: The study design was an exploratory, early phase 2 study that ran for 8 weeks. It was a randomized, multicenter, double-blind, placebo-controlled, parallel-group study, and performed in a dose escalation manner. There were four study arms consisting of dotinurad 1, 2, or 4 mg, and placebo. The primary endpoint was the percent change in serum uric acid level from the baseline to the final visit. The secondary endpoint was the percentage of patients achieving a serum uric acid level ≤ 6.0 mg/dL at the final visit. Results: A total of 80 hyperuricemic patients with or without gout were enrolled and randomly assigned to the dotinurad or placebo groups. The mean percent change in serum uric acid level from the baseline to the final visit in the dotinurad 1, 2, 4 mg, and placebo groups was 37.03%, 50.91%, 64.37%, and 0.85%, respectively. The percentages of patients achieving a serum uric acid level ≤ 6.0 mg/dL at the final visit in each group were 75.0%, 89.5%, 95.2%, and none, respectively. The incidence of adverse events was comparable among all groups. Conclusion: Dotinurad has a substantial serum uric acid lowering effect in patients with hyperuricemia. No serious adverse event was found. ClinicalTrials.gov Identifier: NCT02344862 [ABSTRACT FROM AUTHOR] |
