ListOutcomeTime frameDescription
PrimaryTime to First Achieve Initial Prespecified SBP Target Range and 15% Reduction From Baseline Within First 30 MinutesInitiation of study drug through the initial 30-minutes
Time to first achieve the initial pre-specified systolic blood pressure (SBP) target range and a 15% SBP reduction from baseline is the time in minutes between the initiation of study medication and the time the patient first achieved both components. Median time was estimated using Kaplan Meier method. 95% two-sided confidence interval of the median time is from 'Simon and Lee, 1982'. If patients did not reach both components within 30 minutes from the initial treatment with study medication, or another antihypertensive agent was administered, the patient was censored at 30 minutes or the time when another antihypertensive agent is given, whichever came first.
PrimaryPercentage to First Achieve Initial Prespecified SBP Target Range [≥20 mm Hg and ≤40 mm Hg Apart] and 15% Reduction From Baseline Within First 30 MinutesInitiation of study drug through the initial 30-minutes
Analysis of the percentage of patients achieving both components of this composite endpoint (attainment of the initial prespecified SBP target range and a 15% reduction in SBP from baseline) was calculated within each treatment group using the number of mITT patients achieving the SBP reduction goal divided by the number of mITT patients, and multiplied by 100.
SecondaryPercentage Reaching Prespecified Target Range Without Falling Below Lower Limit of Target Range Within First 30 MinutesInitiation of study drug through the initial 30-minutes
The percentage of patients reaching this endpoint was calculated within each treatment group using the number of mITT patients reaching the endpoint divided by the number of mITT patients, and multiplied by 100. Two-tailed 95% CIs were computed for these percentages.
SecondarySBP Area Under the Curve (AUC) Outside Prespecified Target RangeInitiation of study drug through end of monotherapy (up to 96 hours)
The magnitude and duration of SBP excursions was calculated as the area under the curve (AUC) for each patient, using the trapezoidal rule, related to time (in minutes) that each patient's SBP was outside the target range. AUC was determined based on data collected from the initiation of study medication through the end of monotherapy treatment up to 96 hours, normalized per hour, and expressed as mmHg × minute/hour.
SecondaryPercentage Falling Below Lower Limit of SBP Target Range Within First 30 MinutesInitiation of study drug through the initial 30-minutes
The percentage of patients in whom the SBP fell below the lower limit of the prespecified target range at any time during the first 30 minutes was calculated within each treatment group using the number of mITT patients achieving the endpoint divided by the number of mITT patients and multiplied by 100. Two-tailed 95% CIs were computed for these percentages.
SecondaryPercentage Falling Below Lower Limit of SBP Target Range at Any Time During StudyInitiation through termination of study drug (up to 96 hours)
The percentage of patients in whom the SBP fell below the lower limit of the prespecified target range at any time during the entire study drug treatment period (up to 96 hours) was calculated within each treatment group using the number of mITT patients achieving the endpoint divided by the number of mITT patients and multiplied by 100. Two-tailed 95% CIs were computed for these percentages.
SecondaryChange From Baseline in Dyspnea (Measured By VAS) at Each Time PointBaseline (immediately prior to study drug administration) through 1 hour after study drug termination
A validated visual analog scale (VAS) with a horizontal ruler showing increments from 0 to 100 mm with 0 = Best and 100 = Worst was used. The test was asked from the patient's perspective and had to be administered with patient sitting. Relative change in VAS from baseline is the value at each time point minus the baseline value. Relative change from baseline was summarized descriptively (with associated two-tailed 95% CIs of the mean values) at 15, 30 and 45 minutes and at 1, 2, 3 hours and 12 hours, and 1 hour post termination of study drug treatment.
SecondaryTime to Use Other IV Antihypertensives During the Study Drug AdministrationInitiation of study drug through any other concomitant IV antihypertensive agent administered, up to 96 hours
The length of time to use other IV antihypertensive agents was defined as the duration in hours from the initiation of study drug through the time when any other concomitant IV antihypertensive agent was administered, thus, representing the time period without use of any other concomitant IV antihypertensive agent. Median time to use other IV antihypertensive agents was obtained using Kaplan-Meier method. If a patient did not receive any concomitant IV antihypertensive during the 96-hour treatment period, this patient was considered censored at 96 hours. If study drug was stopped less than 96 hours and the patient has no concomitant IV antihypertensive agent, the patient was considered censored when study drug was stopped.
SecondaryPercentage of Patients Who Received Any Alternative IV Antihypertensive Drug at Any Time During Study Drug TreatmentInitiation through termination of study drug (up to 96 hours)
The percentage of patients who received any alternative IV antihypertensive drug at any time during the study drug treatment period (up to 96 hours) was calculated using mITT patients within each treatment group.
SecondaryPercentage of Patients With at Least One Episode of SBP < 90 mm Hg During Study Drug Administration (up to 96 Hours)Initiation through termination of study drug (up to 96 hours)
The percent of patients with at least one episode of SBP \<90 mm Hg was calculated as the number of mITT patients who had at least one episode of SBP\<90 mm Hg during study drug administration up to 96 hours divided by mITT patients, and multiplied by 100 for each treatment group.
