  Purpose

This is a phase IV, open-label, prospective cohort study for 7 days.The recommended starting dose of tolvaptan is 15 mg daily orally. The dose may be titrated on the next day at 15 mg intervals up to 60 mg daily according to the serum sodium level response.Serum sodium level, change in sodium level from baseline, quality of life (EQ-5D-3L), change in body weight, edema, renal function, mortality and liver-related complications on day 7 and day 30 to evaluate the efficacy of tolvaptan in cirrhotic patients with hyponatremia.

Primary Outcome Measures:
  • the proportion of subjects with normal serum sodium level (135-145 mmol/l) [ Time Frame: day 7 ] [ Designated as safety issue: No ]
    evaluate the efficacy of tolvaptan in cirrhotic patients with hyponatremia


Secondary Outcome Measures:
  • change in sodium level from baseline [ Time Frame: day 7 and day 30 ] [ Designated as safety issue: No ]
    evaluate the efficacy of tolvaptan in cirrhotic patients with hyponatremia

  • quality of life (EQ-5D-3L) [ Time Frame: day 7 and day 30 ] [ Designated as safety issue: No ]
    evaluate the efficacy of tolvaptan in cirrhotic patients

  • change in body weight [ Time Frame: day 7 and day 30 ] [ Designated as safety issue: No ]
    evaluate the efficacy of tolvaptan in cirrhotic patients with hyponatremia

  • edema [ Time Frame: day 7 and day 30 ] [ Designated as safety issue: No ]
    evaluate the efficacy of tolvaptan in cirrhotic patients with hyponatremia

  • renal function [ Time Frame: day 7 and day 30 ] [ Designated as safety issue: Yes ]
    evaluate the short- to intermediate-term safety of tolvaptan in cirrhotic patients

  • mortality and liver-related complications [ Time Frame: day 7 and day 30 ] [ Designated as safety issue: Yes ]
    evaluate the short- to intermediate-term safety of tolvaptan in cirrhotic patients

Tolvaptan Group
Tolvaptan
Drug: Tolvaptan(OPC-41061)
Tolvaptan (OPC-41061) is a benzazepine derivative synthesized by Otsuka Pharmaceutical Company, Ltd. Tolvaptan was approved for the treatment of specific forms of hyponatremia by the United States (US) Food and Drug Administration (FDA) in May 2009, the European Medicines Agency on Aug 2009, Japan (Oct 2010), China (Sep 2011) and Korea (Sep 2011). Tolvaptan was approved for the adjunct treatment of volume overload in heart failure by the Japanese Ministry of Health, Labour, and Welfare (MHLW) in Oct 2010. It is also being developed for the treatment of autosomal dominant polycystic kidney disease (ADPKD), and for the treatment of hepatic edema.
Conventional therapy
control group:Conventional therapy without tolvaptan

Detailed Description:

Tolvaptan is an effective treatment for hyponatremia. However, cirrhotic patients were underrepresented in previous studies. The pattern of use and efficacy of tolvaptan in real-life clinical practice are currently unknown.The objective of this study is to evaluate the efficacy of tolvaptan in cirrhotic patients with hyponatremia. The secondary objective is to evaluate the short- to intermediate-term safety of tolvaptan in cirrhotic patients.This will be a phase IV, open-label, prospective cohort study for 7 days. Although not mandatory, study subjects are encouraged to undergo follow-up assessments at 1 month.Subjects will be evaluated at designated time points after initiation of therapy. The primary efficacy endpoint is the proportion of subjects with normal serum sodium level (135-145 mmol/l) on day 7. The secondary efficacy endpoints are serum sodium level, change in sodium level from baseline, quality of life (EQ-5D-3L), change in body weight, edema, renal function, mortality and liver-related complications on day 7 and day 30.
