About this study

Official title: A Phase-3b, Randomized, Double-Blind, Placebo-Controlled, Multi-Center Study to Assess the Safety and Efficacy of Conivaptan in Symptomatic Acute Decompensated Heart Failure (ADHF) Subjects With Hyponatremia

This study will evaluate the safety and effectiveness of Conivaptan, a vasopressin antagonist, in the treatment of hyponatremic subjects having symptomatic acute decompensated heart failure (ADHF).

Read the detailed description

Subjects will be recruited from the Emergency Department. It is expected that subjects will be treated according to the institution's accepted conventional therapy protocol for the treatment of ADHF. Therapy may also include the use of loop diuretics for the relief of pulmonary congestion and maintenance of adequate urine output.

What is being measured

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

  1. Change in Renal Function From Baseline at 72 Hours Assessed by Calculated Creatinine Clearance (MDRD Equation)

    MDRD = Modification of Diet in Renal Disease

    The MDRD equation is a standard calculation for estimated glomerular filtration rate.

    Outcome Measures were not analyzed due to the abbreviated enrollment at early study termination.

    Measured: Baseline and 72 Hours

  2. Assessment of Dyspnea at 24 Hours as Determined by a 7-point Likert Scale

    Dyspnea is defined as the sensation of uncomfortable or difficult breathing.

    Changes in Dyspnea were assessed using the following 7-point scale: 1-Markedly worse; 2-Moderately worse; 3-Mildly worse; 4-No change; 5-Mildly improved; 6-Moderately improved; 7-Markedly better/improved.

    Outcome Measures were not analyzed due to the abbreviated enrollment at early study termination.

    Measured: 24 Hours

Secondary outcomes (9)
  1. Change in Renal Function From Baseline at Hours 24, 48 and 72 as Assessed by Urine Creatinine Clearance

    Outcome Measures were not analyzed due to the abbreviated enrollment at early study termination.

    Measured: Baseline, 24 Hours, 48 Hours and 72 Hours

  2. Change in Renal Function From Baseline at Hours 24, 48 and Day 9 (or Day of Discharge) as Assessed by Serum Creatinine Concentration and Calculated Creatinine Clearance

    Calculated creatinine clearance is only calculated through hour 72 using the MDRD equation.

    MDRD = Modification of Diet in Renal Disease

    The MDRD equation is a standard calculation for estimated glomerular filtration rate.

    Outcome Measures were not analyzed due to the abbreviated enrollment at early study termination.

    Measured: Baseline, 24 Hours, 48 Hours and Day 9

  3. Incidence of Use of Rescue Therapy or Other Intervention (Including Dialysis) Because of Worsening Renal Function

    Outcome Measures were not analyzed due to the abbreviated enrollment at early study termination.

    Measured: Day 9

  4. Termination of Study Drug Due to an Adverse Event or Intolerability

    Outcome Measures were not analyzed due to the abbreviated enrollment at early study termination.

    Measured: 48.5 Hours

  5. Assessment of Dyspnea at Baseline, Hours 6, 12, 24 and 48 Using a Relative Dyspnea Assessment

    Dyspnea is defined as the sensation of uncomfortable or difficult breathing.

    Changes in Dyspnea were assessed using the following 7-point Likert scale:

    1-Markedly worse; 2-Moderately worse; 3-Mildly worse; 4-No change; 5-Mildly improved; 6-Moderately improved; 7-Markedly better/improved.

    Outcome Measures were not analyzed due to the abbreviated enrollment at early study termination.

    Measured: Baseline, 6 Hours, 12 Hours, 24 Hours and 48 Hours

  6. Assessment of Dyspnea at Baseline, Hours 6, 12, 24 and 48 Using a Provocative Dyspnea Assessment

    Dyspnea is defined as the sensation of uncomfortable or difficult breathing.

    The Provocative Dyspnea Assessment assesses dyspnea and changes in dyspnea from Baseline on a 5-point Likert scale at 5 different positions and assigns a Dyspnea Severity Score that ranges from 1 (worst severity) to 25 (least severity).

    Outcome Measures were not analyzed due to the abbreviated enrollment at early study termination.

    Measured: Baseline, 6 Hours, 12 Hours, 24 Hours and 48 Hours

  7. Change From Baseline in Body Weight at Hours 24, 48 and 72 and Days 6 and 9 (or Day of Discharge)

    Outcome Measures were not analyzed due to the abbreviated enrollment at early study termination.

    Measured: Baseline, 24 Hours, 48 Hours, 72 Hours, Day 6 and Day 9

  8. Total Loop Diuretic Use Through 48 Hours

    Outcome Measures were not analyzed due to the abbreviated enrollment at early study termination.

    Measured: 48 Hours

  9. Total Urine Output at Hours 6, 12, 24, 48 and 72

    Outcome Measures were not analyzed due to the abbreviated enrollment at early study termination.

    Measured: 6 Hours, 12 Hours, 24 Hours, 48 Hours and 72 Hours

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing conivaptan in people with Hyponatremia and Acute Decompensated Heart Failure, run by Cumberland Pharmaceuticals at 4 sites in India.

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 6 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 15 May 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in India. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 1 Oct 2010). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Change in Renal Function From Baseline at 72 Hours Assessed by Calculated Creatinine Clearance (MDRD Equation) (time frame: Baseline and 72 Hours). The study lists 2 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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 May 2014.
