Simple DNA test could shield gout patients from deadly skin side effects
NCT ID NCT07369622
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a genetic test can prevent rare but severe skin reactions caused by the common gout drug allopurinol. About 228 Vietnamese adults with gout will either get the test before treatment or receive standard care. Those with a high-risk gene will take a different drug (febuxostat) instead. The goal is to see if this approach is safer and cost-effective.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- allopurinol and febuxostat
- What this could lead to
- If successful, this approach could prevent life-threatening skin reactions in people starting gout treatment, making therapy safer for those with a specific genetic risk.
- What could go wrong
- This is a small, single-site study in Vietnam, so results may not apply to other populations. The genetic test is only for one risk factor, and other rare reactions could still occur.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age ≥ 18 years. Diagnosis of gout according to the 2020 ACR/EULAR classification criteria. Indicated for initiation of urate-lowering therapy (ULT) and allopurinol-naïve (no prior allopurinol exposure). Able and willing to comply with scheduled follow-up visits (baseline, Months 1, 3, 6, and 12). Provides written informed consent for participation. For the genotyping arms: provides consent for blood sampling and HLA-B\*58:01 genotyping. Exclusion Criteria: * Prior use of allopurinol or history of hypersensitivity reaction to allopurinol. Known hypersensitivity to febuxostat (for participants who would receive febuxostat). Current or recent severe skin reaction (suspected/confirmed SCAR) from any cause. End-stage kidney disease requiring dialysis or kidney transplantation. Severe hepatic impairment or active severe liver disease (e.g., AST/ALT \>3× ULN at baseline). Severe uncontrolled medical conditions that, in the investigator's judgment, could interfere with treatment or follow-up (e.g., decompensated heart failure, active malignancy requiring intensive treatment). Use of systemic immunosuppressive therapy (e.g., high-dose corticosteroids, biologics, chemotherapy) at enrollment. Pregnancy or breastfeeding. Participation in another interventional clinical study that could affect the outcomes of this study. Inability to provide informed consent or inability to adhere to study procedures.
