CLINICAL TRIALS PROFILE FOR URIDINE TRIACETATE

All Clinical Trials for URIDINE TRIACETATE

Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT01432301 ↗	Uridine Triacetate as Antidote for Patients at Excess Risk of 5-FU Toxicity Due to Overdosage or Impaired Elimination	Approved for marketing	Wellstat Therapeutics		1969-12-31	The purpose of this study is to provide emergency treatment of adult and pediatric patients: - Following a fluorouracil or capecitabine overdose regardless of the presence of symptoms or - Who exhibit early-onset, severe or life-threatening toxicity affecting the cardiac or central nervous systems, and/or early-onset, unusually severe adverse reactions (e.g., gastrointestinal toxicity and/or neutropenia) within 96 hours following the end of fluorouracil or capecitabine administration.
NCT02110147 ↗	Open-Label Study of Uridine Triacetate in Pediatric Patients With Hereditary Orotic Aciduria	Completed	Wellstat Therapeutics	Phase 3	2014-04-01	This protocol has two parts - the Main Study which is 42 days in length and the Treatment Extension which allows the patients who complete the Main Study to continue receiving treatment with uridine triacetate. The purpose of this study is to replace oral administration of uridine with oral administration of uridine triacetate in patients with hereditary orotic aciduria who have received (or would reasonably be expected to receive) clinical benefit from treatment with exogenous uridine. It is also to document the continued clinical benefit of exogenous uridine when patients are switched from oral administration of uridine to oral administration of uridine triacetate.
NCT07032142 ↗	Dose Optimization and Efficacy Assessment of a Fluoropyrimidine Antidote	NOT_YET_RECRUITING	Conselho Nacional de Desenvolvimento Cientfico e Tecnolgico	PHASE1	2025-07-01	Fluoropyrimidines (FLU) are drugs widely used in chemotherapy for various tumors, such as breast, colon, rectal, and gastric cancers. FLU is a drug that inhibits thymine synthesis and, consequently, DNA synthesis, leading to tumor cell death. However, up to 30% of patients treated with FLU experience severe toxicities, depending on the dose and regimen received. The most common symptoms include mucositis, vomiting, nausea, diarrhea, and neutropenia. The enzyme dihydropyrimidine dehydrogenase (DPD) plays a key role in FLU metabolism. Patients with mutations in the DPYD gene (which encodes DPD) are at high risk of experiencing severe toxicities from FLU. Uridine triacetate (UT) is a drug that can be used as an antidote for 5-FU in patients who develop severe toxicities. However, despite its efficacy, it is expensive and not commercially available in Brazil. Currently, the Brazilian population has no access to an antidote for the treatment of FLU-related toxicities. This Phase I/II study will evaluate the dose, safety, and efficacy of compound the association of two molecules as an antidote for grade 3 or higher toxicities resulting from the use of FLU.
