About this study

Official title: Multicenter Tolvaptan Study For Uncontrolled Volume Overload in Japanese Acute Decompensated Heart faIlure Patients: A Prospective Observational Multicenter Cohort Study

The aims of the present study are to investigate prospectively the clinical course and outcome of the hospitalized heart failure patients treated with tolvaptan for management of fluid retention and serum sodium levels of less than 140 mEq/L and also to analyze the factors related with the efficacy including outcome of tolvaptan therapy.

Read the detailed description

Vasopressin mediates fluid retention in heart failure. Tolvaptan, an oral, nonpeptide, selective vasopressin V2-receptor antagonist, shows promise for management of heart failure.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Efficacy 1) Alleviation of the signs of body fluid retention 2) Change of body weight 3) Changes in the daily urinary volume

    1. Alleviation of the signs of body fluid retention by the 7th day of treatment with tolvaptan (or the day of discontinuation of the drug in cases where tolvaptan treatment has been discontinued before the 7th day) as compared with the observations made on the day before the start of treatment 2) Change of body weight by the 7th day of treatment with tolvaptan as compared with the level measured on the day before the start of treatment 3) Changes in the daily urinary volume by the 7th day of treatment with tolvaptan as compared with the values measured on the day before the start of treatment

    Measured: At the day of discontinuation of tolvaptan or day 7, whichever comes first

  2. Safety: adverse events Adverse events until 30 days after the end of treatment with tolvaptan

    Measured: 30 days after tolvaptan withdrawal

  3. Long-term outcome (1 year after tolvaptan administration) 1) Time from enrollment to cardiovascular events 2) Time from enrollment to re-hospitalization for aggravation of heart failure 3) Time from enrollment to all-cause death

    1. Time from enrollment to cardiovascular events within 1 year after administration of tolvaptan 2) Time from enrollment to re-hospitalization for aggravation of heart failure within 1 year after administration of tolvaptan 3) Time from enrollment to all-cause death within 1 year after administration of tolvaptan

    Cardiovascular events included death from heart failure, death from acute coronary syndrome, death from stroke, sudden death, death of unknown causes, death from other cardiovascular causes, readmission for heart failure, ventricular arrhythmia, acute coronary syndrome, and stroke.

    Measured: 1 year after administration of tolvaptan

Secondary outcomes (1)
  1. Search for the factors related with the efficacy of tolvaptan therapy and long-term outcome 1) related factors regarding efficacy of tolvaptan 2 ) related factors regarding long-term outcome

    Exploratory analysis will be performed to determine which factors relate with the efficacy of tolvaptan therapy or long-term outcome. Factors will include age, gender, medical past history, medication, NYHA classification, Nohria/Steavenson classification, laboratory data (Na, K, Cl, Albumin, Cr, BUN, AST, ALT, gamma-GTP, LDH, T-Bil, BNP, NT-pro BNP, copeptin, galectin-3,aldosteron,angiotensin II, renin, noradrenaline), heart rate, blood pressure, echocardiography data, intake/urine volume and osmolality.

    Measured: 1 year after administration of tolvaptan

Questions about this trial

What is this clinical trial studying?

An observational study of Heart Failure, run by Translational Research Center for Medical Innovation, Kobe, Hyogo, Japan at 1 site in Japan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 2 Jun 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Efficacy 1) Alleviation of the signs of body fluid retention 2) Change of body weight 3) Changes in the daily urinary volume (time frame: At the day of discontinuation of tolvaptan or day 7, whichever comes first). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
