Outcomes
Primary Outcome Measures
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
Secondary Outcome Measures
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.
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.
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.
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.
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.
