What is being measured

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

Number and Severity of Infusion Site Reactions (ISRs) Using a Modified ISR Reporting Scale for Phlebitis and Infiltration in Patients Treated With Dose Regimen 1 and Dose Regimen 2
Infusion Site Reaction (ISR) was any local event other than isolated pain, bleeding, or bruising at the site of infusion.
One ISRMS has been reported for each participant \& represents the most severe state of ISR for that participant.
ISR scale is a health care provider assessment of ISRs using the following modified 5 point reporting scale: 0= No new reaction; 1+=Infusion site erythema, infusion site pain, infusion site warmth; 2+= Infusion site edema; 3+=Phlebitis, venous induration; 4+=Thrombophlebitis, venous thrombosis, infusion site infection, infusion site cellulitis
Measured: 48 hours

Secondary outcomes (5)

Change From Baseline in Serum Sodium at Each Time Point Over the Duration of the Treatment Period and 7-day Post Treatment Period
Baseline serum sodium value is the average of 2 serum sodium values taken at least 4 hours apart on Day-1 and within 24 hours of Hour 0 in the Treatment Period.
Change from Baseline is calculated as Time point minus Baseline.
Measured: Baseline at 4, 6, 10, 16, 24, 30, 40, 48.5 hours and 7 days post-treatment
Baseline Adjusted Area Under the Concentration - Time Curve (AUC) in Serum Sodium Over the Duration of the First 24.5 Hours, the First 48.5 Hours, and the First 96.5 Hours
AUCna t is calculated as the baseline-adjusted area under serum sodium levels for a duration of time 0 to time t.
Baseline serum sodium value is the average of 2 serum sodium values taken at least 4 hours apart on Day-1 and within 24 hours of Hour 0 in the Treatment Period.
Measured: 24.5 hours, 48.5 hours and 96.5 hours
Time From the First Dose of Study Drug to a Confirmed > 4 mEq/L Increase From Baseline in Serum Sodium During the 48.5 Hour Treatment Period
The upper limits of the interquartile range were not estimable in three of the treatment arms. Only the "placebo loading dose + YM087 premix continuous infusion" arm will be reported.
Time is number of hours to reach an increase of exceeding 4 mEq/L from baseline serum sodium.
Baseline serum sodium value is the average of 2 serum sodium values taken at least 4 hours apart on Day-1 and within 24 hours of Hour 0 in the Treatment Period.
Measured: 48.5 hours
Number of Patients With Confirmed Serum Sodium Level Exceeding 4 mEq/L Increase From Baseline Over the Duration 0-24.5 Hours, 0-48.5 Hours, and 0-96.5 Hours
Patients with confirmed serum sodium level exceeding 4 mEq/L increase from baseline.
Baseline serum sodium value is the average of 2 serum sodium values taken at least 4 hours apart on Day-1 and within 24 hours of Hour 0 in the Treatment Period.
Measured: 0-24.5 hours, 0-48.5 hours and 0-96.5 hours
Number of Patients With Confirmed Serum Sodium Level Exceeding 6 mEq/L Increase From Baseline or Confirmed Normal Serum Sodium Level Exceeding 135 mEq/L Over the Duration 0-24.5 Hours, 0-48.5 Hours, and 0-96.5 Hours
Patients with confirmed serum sodium level exceeding 6 mEq/L increase from baseline or confirmed normal serum sodium level exceeding 135 mEq/L.
Baseline serum sodium value is the average of 2 serum sodium values taken at least 4 hours apart on Day-1 and within 24 hours of Hour 0 in the Treatment Period.
Measured: 0-24.5 hours, 0-48.5 hours and 0-96.5 hours

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Conivaptan in people with Hyponatremia and Euvolemia, run by Cumberland Pharmaceuticals at 18 sites in 3 countries.

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 2 inclusion and 2 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: finished, 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 18 sites in Israel, India, United States. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 26 May 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?

Number and Severity of Infusion Site Reactions (ISRs) Using a Modified ISR Reporting Scale for Phlebitis and Infiltration in Patients Treated With Dose Regimen 1 and Dose Regimen 2 (time frame: 48 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00435591, which also lists 1 linked publication.

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; AzTrials last refreshed its copy on 7 Nov 2026.
