Pre-Clinical

Earlier treatment improved survival in animal studies

After a lethal dose of 5-FU in animal studies4

Vistogard
when VISTOGARD® dosing
began at 24 hours

Time window for treatment: uridine triacetate (2 g/kg every 8 hours for 15 doses over 5 days) was initiated at 24, 48, 74, and 96 hours (n=10/group) after a lethal overdose of 5-FU (300 mg/kg) in normal mice.5

The clinical significance of animal studies is unknown.

  • Survival diminished with increasing interval between the 5-FU dose and uridine triacetate treatment, indicating that earlier administration is more beneficial4
  • In mice given a sub-lethal dose of 5-FU, the administration of oral uridine triacetate diminished but did not completely prevent hematological toxicity as a function of increasing dose

Important Safety Information

  • In clinical studies, adverse reactions occurring in >2% of patients receiving VISTOGARD® included vomiting (10%), nausea (5%), and diarrhea (3%).
  • One person receiving uridine triacetate experienced grade 3 nausea and vomiting.
  • VISTOGARD® was discontinued for adverse reactions in 2 (1.4%) patients.
