Full description
The aim of this study was to evaluate the safety, tolerability, and pharmacokinetic characteristics of TNP-2092 Capsules in liver cirrhosis patients with hyperammonemia; and to preliminarily observe the effects of the study drug on blood ammonia and hepatic encephalopathy related clinical symptoms and signs, neuropsychological indicators, and quality of life in liver cirrhosis patients with hyperammonemia.
A total of 3 dose groups will be set up, i.e., 100 mg BID, 300 mg BID and 600 mg BID groups. Drugs will be orally administered 30 min after breakfast and dinner for 14 consecutive days, and last dose will be administered 30 min after breakfast on the morning of D15. Each dose group will include a study drug TNP-2092 capsule arm and a placebo control arm. Subjects will exit upon completion of the safety and tolerability evaluation on D17.
Twelve liver cirrhosis patients with hyperammonemia are planned to be enrolled in each dose group. The 12 patients will be assigned in a ratio of 2:1 to the TNP-2092 capsule arm and the placebo arm, with 8 patients receiving TNP-2092 Capsules and 4 receiving placebos.
Enrollment for the second dose group may start only after the previous dose group has fully completed the treatment period and passed the safety and tolerability evaluation.
