and Rationale Hyperuricemia, a common metabolic disorder characterized by elevated serum urate due to purine metabolism dysfunction, affects 14.0% of Chinese adults (24.5% in men, 3.6% in women). Elevated serum urate leads to crystal deposition in joints, soft tissues, and kidneys, contributing not only to gout flares but also to renal and other organ damage. Although urate-lowering therapies (e.g., febuxostat, benzbromarone) effectively control serum urate, current guidelines do not recommend early pharmacological intervention for asymptomatic hyperuricemia due to safety concerns. Thus, additional strategies beyond lifestyle guidance are needed for this population.\n\nPrior Research A prospective randomized study by the Affiliated Hospital of Qingdao University in 182 gout patients showed that a citrate mixture had comparable urate-lowering and urine alkalinization effects to sodium bicarbonate. After 3 months, the citrate effervescent tablet was superior in reducing hematuria and gout recurrence. Tart cherries, rich in anti-inflammatory and antioxidant anthocyanins, have been shown overseas to improve cardiovascular risk factors (blood pressure, cholesterol, blood glucose). The tart cherry citrate effervescent tablet enhances the original citrate mixture with increased citric acid and added tart cherry components.\n\nA 24-week randomized, open-label, parallel-controlled trial in 282 male gout patients (fasting urine pH ≤6) demonstrated that the tart cherry citrate effervescent tablet had similar efficacy and safety to citrate mixture and sodium bicarbonate for urine alkalinization and serum urate lowering. However, it produced greater improvements in urinary albumin-to-creatinine ratio (UACR) and C-reactive protein (CRP), significantly reduced gout flare frequency, and improved metabolic parameters (systolic\u002Fdiastolic blood pressure, fasting glucose, homeostasis model assessment-insulin resistance \\[HOMA-IR\\], total cholesterol).\n\nStudy Objectives To evaluate the efficacy and safety of tart cherry citrate effervescent tablet in participants with asymptomatic hyperuricemia.\n\nTrial Design\n\n* Design: Randomized, placebo-controlled, parallel-group trial.\n* Number of participants: 196 (1:1 randomization).\n* Randomization method: Block randomization.\n* Sample size calculation: Based on a pilot study of tart cherry citrate mixture (mean serum urate changes: 54±65 μmol\u002FL in active group vs. 30±19 μmol\u002FL in lifestyle guidance group), 65 participants per group provided \\>80% power at α=0.05 to detect the difference. Accounting for a 20-25% dropout rate over 12 weeks and extending observation to 24 weeks, the sample size was increased by 50%, resulting in 196 total participants.\n* Study population: Participants with primary asymptomatic hyperuricemia who voluntarily sign informed consent and meet eligibility criteria.\n\nTreatment Regimen\n\n* Experimental group: Lifestyle guidance + tart cherry citrate effervescent tablet 4.0 g twice daily (bid)\n* Placebo control group: Lifestyle guidance + matching placebo effervescent tablet\n* Daily water intake: 2000-2500 mL. Two effervescent tablets taken morning and evening (with or without meals).\n* Lifestyle guidance: face-to-face and WeChat group-based regular dietary advice, exercise guidance, and education on recognizing gout flares.\n\nDetails are provided in the study protocol.\n\nStudy Duration 24 weeks.\n\nOutcome Measures\n\nEfficacy outcomes:\n\n* Serum uric acid (sUA) at 12 and 24 weeks\n* Morning urine pH\n* 24-hour urinary uric acid excretion (UUE)\n* New-onset gout flares\n* Changes in kidney stones\n* Urate crystal volume by dual-energy computed tomography (DECT)\n* C-reactive protein (CRP)\n* Renal function (estimated glomerular filtration rate \\[eGFR\\], urinary albumin-to--creatinine ratio \\[UACR\\])\n* Metabolic syndrome components (fasting blood glucose \\[FBG\\], blood pressure, lipid profile)\n\nSafety outcomes:\n\n* Vital signs\n* Adverse events (AEs)\n* Safety laboratory parameters (routine blood\u002Furine tests, liver\u002Frenal function, -electrolytes)\n\nEfficacy Evaluation\n\nPrimary outcome:\n\n-Difference in serum urate (sUA) levels between groups at week 24.\n\nSecondary outcomes:\n\n* Differences in sUA at week 12 and week 24\n* Change in sUA within experimental group from baseline to week 24\n* Differences in morning urine pH at week 12 and week 24\n* Changes in urine components (hematuria, UACR, urine crystals) from baseline to week 24\n* Changes in 24-hour UUE from baseline to week 24\n* Differences in eGFR and UACR between groups at week 12 and week 24\n* Changes in eGFR and UACR within groups from baseline to week 24\n* Changes in metabolic outcomes (FBG, blood pressure, total cholesterol, triglycerides, HDL cholesterol, LDL cholesterol, HOMA-IR) between groups at week 12 and week 24\n* Changes in metabolic outcomes within experimental group from baseline to week 24\n* Number of participants with new-onset gout flares during the 24-week treatment period\n* Changes in kidney stone size (mm) within groups from baseline to week 24\n\nSafety Evaluation Monitoring of vital signs at each visit Clinically significant changes in safety laboratory parameters Documentation and assessment of all adverse events\n\nConclusion This randomized, placebo-controlled trial will compare the effects of tart cherry citrate effervescent tablet versus placebo plus lifestyle guidance on serum urate reduction in participants with asymptomatic hyperuricemia.
