A Phase III Study Evaluating the Efficacy and Safety of Satavaptan Versus Placebo in Patients With Dilutional Hyponatremia (AQUARIST1)

April 26, 2016 updated by: Sanofi

A Double-Blind, Randomized, Placebo-Controlled Multicenter Study Evaluating the Efficacy and Safety of Two Doses of Satavaptan (SR121463B) Versus Placebo in Patients With Dilutional Hyponatremia Due to the Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH)

The primary objective of this study is to assess the efficacy of satavaptan versus placebo in participants with dilutional hyponatremia due to SIADH.

Secondary objectives are to assess the safety of satavaptan, the maintenance of effect, and the clinical benefit in these participants.

Description

Inclusion Criteria:

  • Participants with symptomatic syndrome of inappropriate antidiuretic hormone secretion (SIADH) with chronic hyponatremia

  • Presence of clinical signs of hypervolemia (e.g. generalized edema, jugular venous extension)
  • Participants with adrenocortical insufficiency
  • Participants with hypothyroidism
  • Participants with known causes of transient SIADH
  • Participants with psychogenic polydipsia or beer potomania
  • Concomitant use of thiazide diuretics during the study
  • Presence of uncontrolled diabetes with fasting blood glucose ≥200 mg/dL (≥11.09 mmol/L) at time of screening
  • Participants with impaired hepatic function or liver cirrhosis (Child-Pugh A-C)
  • Pregnant or breast-feeding women
