EXPERIMENTAL: clevidipine
This will be a single-arm study with no reference therapy.
|
Clevidipine injectable emulsion (0.5 mg/mL) in 20% lipid emulsion in 100 mL bottles was administered intravenously to all patients via a single dedicated line. Clevidipine was infused at an initial rate of 2.0 mg/h for the first 1.5 minutes. Thereafter, titration to higher infusion rates were to be attempted as needed to obtain the target systolic blood pressure (SBP) range (SBP ≤160 mmHg to ≥140 mmHg). Titration to effect was to proceed by doubling the dose every 1.5 minutes, up to a maximum of 32.0 mg/h, until the desired effect (SBP within the target range) was attained. The clevidipine infusion rate could be increased or decreased to maintain systolic blood pressure for up to a maximum of 96 hours.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Median Time to Achieve Target SBP Range (≤160 mmHg to ≥140 mmHg) Within 30 Minutes of Initiation of Clevidipine
Time Frame: Within 30 minutes of study drug initiation
|
The median time, in minutes, was estimated with its two-tailed 95% confidence interval from the time of the initiation of clevidipine infusion until the first observed SBP was achieved in the target range of ≤160 mmHg to ≥140 mmHg within the first 30 minutes of clevidipine treatment.
If patients did not reach the blood pressure target range within the first 30 minutes, their data was considered censored at 30 minutes.
If another IV and/or oral antihypertensive agent indicated for hypertension was administered less than 30 minutes prior to achieving the endpoint, the data was considered censored at the time when the additional or alternative antihypertensive agent was given.
|
Within 30 minutes of study drug initiation
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage of Participants Achieving a SBP of ≤160 mmHg Within 30 Minutes of Initiation of Clevidipine
Time Frame: Within 30 minutes of study drug initiation
|
The percentage of patients who reached SBP of ≤160 mmHg within the first 30 minutes of initiation of clevidipine infusion was summarized.
If an additional or alternative IV antihypertensive agent and/or oral antihypertensive agent was administered for hypertension prior to a patient achieving SBP≤160 mmHg during the initial 30-minute treatment period, then the patient was considered to have failed to reach this efficacy endpoint.
|
Within 30 minutes of study drug initiation
|
Percent Change From Baseline in Systolic Blood Pressure During the Initial 30 Minutes of Clevidipine Infusion
Time Frame: Baseline through 30 minutes post initiation of clevidipine infusion
|
Over the initial 30 minutes of the treatment period, the percent change from baseline (defined as immediately prior to study drug initiation) was summarized descriptively at 1, 2, 3, 4, 5, 6, 7, 10, 15, 20, 25, and 30 minutes after clevidipine initiation.
Decreases in SBP from baseline were observed over the course of this time period.
|
Baseline through 30 minutes post initiation of clevidipine infusion
|
Magnitude, Frequency and Duration of Systolic Blood Pressure Excursions (Calculated as Area Under the Curve [AUC]) Outside the Target Range Normalized Per Hour for the Duration of the Clevidipine Monotherapy Infusion
Time Frame: Duration of the study drug infusion (up to 96 hours)
|
Total AUC-SBP captures the magnitude and duration of SBP either above the upper limit of the target SBP range at 160 mm Hg or below the lower limit of 140 mm Hg and normalized per hour for the duration of clevidipine infusion.
A larger value for AUC-SBP indicates greater SBP variability outside the target range.
|
Duration of the study drug infusion (up to 96 hours)
|
Percent Time Blood Pressures Were Maintained Within the Target Range (Systolic Blood Pressure ≤160 mmHg to ≥140 mmHg) Over Each 24 Hour Period During Monotherapy Infusion of Clevidipine
Time Frame: From study drug initiation through termination (up to 96 h)
|
The percent time that SBP was maintained within the SBP target range (≤160 mmHg to ≥140 mmHg) was summarized for each 24-hour period of monotherapy of clevidipine infusion through 96 hours (0 -≤24 h, 24-≤48 h, 48-≤72 h, 72-≤96 h).
For purposes of this analysis, SBP data were available from all mITT patients for the overall infusion period and from 0 to ≤24 hours of infusion; however, data was only available for 8 patients from 24 to ≤48 hours, 4 patients from 48 to ≤72 hours and 1 patient from 72 to ≤96 hours due to the variability in infusion durations >24 hours across patients.
|
From study drug initiation through termination (up to 96 h)
|
Mean Dose of Clevidipine During the Treatment Period
Time Frame: Up to 96 hours
|
Mean total dose of clevidipine from study drug initiation to the end of clevidipine treatment
|
Up to 96 hours
|
Median Dose of Clevidipine During the Treatment Period
Time Frame: Up to 96 hours
|
Mean total dose of clevidipine from study drug initiation to the end of clevidipine treatment
|
Up to 96 hours
|
Proportion of Patients Requiring an Additional or Alternative Antihypertensive Agent(s) With or Without Clevidipine
Time Frame: Up to 96 hours
|
Additional or alternative antihypertensive agent(s) comprise the use of other antihypertensive agent(s) either with clevidipine (additional) or in place of clevidipine (alternative) for the indication of hypertension from the time of clevidipine initiation to clevidipine termination.
For purposes of this analysis, additional or alternative antihypertensive agents did not include oral antihypertensives that were administered in order to transition IV clevidipine-treated patients to oral therapy during the transition period of the study.
|
Up to 96 hours
|
Percent Change in Heart Rate During 30 of Initiation of Clevidipine
Time Frame: From study drug initiation through each specified timepoint
|
Multiple timepoints were assessed (minutes 1, 2, 3, 4, 5, 10, 15, 20, 30) for analysis of percent change in heart rate during the initial 30 minutes.
|
From study drug initiation through each specified timepoint
|
The Percentage of Patients Whose Systolic Blood Pressure is <90 mmHg Within 30 Minutes of the Initiation of Clevidipine Infusion
Time Frame: Within 30 minutes of the initiation of study drug infusion
