简要总结
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.
详细描述
Data to be collected during the Main Study include demographic, baseline disease information and medical history including all prior disease-directed therapy. In addition, vital signs, laboratory values and adverse events information will be collected and recorded. Urine samples will be obtained and measured for orotic acid and orotidine levels. Systemic levels of uridine will be evaluated from plasma samples collected at set timepoints.
Upon successful completion of the Main Study and entry into the Treatment Extension, physical exams and vital signs will be performed every six (6) months. Additionally, plasma samples to measure systemic levels of uridine and urine samples to measure levels of orotic acid and orotidine will be collected every (6) six months.

研究组 & 干预措施
Uridine Triacetate to Replace Uridine
Replacement therapy for oral 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. The starting dose of uridine triacetate will be 60 mg/kg/day which may be escalated to 300 mg/kg/day of oral uridine triacetate. The dose may be given once a day or as equally divided doses twice a day.
干预措施: uridine triacetate (Drug)
结局指标
主要结局
Patients With Stable Predetermined Principal Hematologic Parameters
时间窗: Days 28 and 42
Hereditary orotic aciduria patients will be taking uridine triacetate as replacement therapy for uridine. The primary outcome measure will be based on predetermined principal hematologic parameter(s) based on the patient's response(s) to oral uridine when dosing is switched from oral uridine to oral uridine triacetate. The primary outcome measure in patients not previously receiving uridine replacement therapy will be improvement in the patient's principal affected hematologic parameter(s) on Days 28 and 42 compared to baseline (Day 0) of the Main Study.
次要结局
- Patients With Stable or Improved Orotic Acid and Orotidine Levels(Days 28 and 42)
- Patients With Levels of Uridine in the Plasma Consistent With Expected Therapeutic Benefit(Days 1 and 28)
