Experimental: clevidipine
An initial clevidipine IV infusion dose for the adolescent cohort has been specified per protocol. The initial dose for each of the subsequent age cohorts will be modified if necessary, based on the recommendation of the Data and Safety Monitoring Board (DSMB). Following the initial dose, clevidipine will be up-titrated every 1.5 minutes, according to participant need, to achieve a systolic blood pressure (SBP) within the pre-specified SBP target range. Doses may be increased by less than doubling, and the time between dose adjustments may be lengthened, as the target blood pressure is approached. The infusion rate may be maintained for up to 96 hours, once the participant's SBP is within the target range, and titrated as necessary to maintain blood pressure within the range. |
Drug: clevidipine
Other Names:
|
- Efficacy: Median time to attain the initial pre-specified target SBP range (≥20 mm Hg and ≤ 40 mm Hg apart) [ Time Frame: During the first 30 minutes of clevidipine infusion ]
- Efficacy: Dose to attain the initial pre-specified target SBP range (≥20 mm Hg and ≤ 40 mm Hg apart) [ Time Frame: During the first 30 minutes of clevidipine infusion ]
- Efficacy: Percentage of participants achieving the initial pre-specified target SBP range [ Time Frame: During the first 30 minutes of clevidipine infusion ]
- Pharmacology: Pharmacokinetic variables [half-life, Area Under the Curve (AUC), volume of distribution, clearance] established by noncompartmental analysis or sparse population methodology [ Time Frame: Through 8 hours post-termination of clevidipine infusion (minimum of 9 hours up to a maximum of approximately 4 1/2 days) ]
- Pharmacology: Pharmacodynamic variables (relationship between change from baseline in SBP versus blood concentration and infusion rate) [ Time Frame: Duration of clevidipine infusion (minimum of 30 minutes up to a maximum 96 hours) ]
- Safety: Safety of a prolonged infusion of clevidipine assessed through clinical laboratory parameters, adverse events and serious adverse events (SAEs) [ Time Frame: Through 7 days post-termination of clevidipine infusion (minimum of approximately 7 1/2 days up to a maximum of approximately 11 1/2 days) ]
- Efficacy: The percentage of participants who reach the initial pre-specified target SBP range without falling below the lower limit of the pre-specified target range [ Time Frame: During the first 30 minutes of clevidipine infusion ]
- Efficacy: The percentage of participants in whom the SBP falls below the lower limit of the pre-specified target range at any time [ Time Frame: During the first 30 minutes of clevidipine infusion ]
- Efficacy: The percentage of participants in whom the SBP falls below the lower limit of the pre-specified target range at any time during the entire study drug treatment period [ Time Frame: Minimum of 30 minutes up to a maximum of 96 hours ]
- Efficacy: The percentage of participants in whom the SBP is within target range at each hour after the first 30 minutes of clevidipine infusion [ Time Frame: 30 minutes post-clevidipine infusion through termination of clevidipine infusion (minimum of <1 minute up to a maximum of 95 1/2 hours) ]
- Efficacy: The percentage of participants who require rescue therapy (i.e. receive any alternative IV antihypertensive drug) at any time during the study drug treatment period [ Time Frame: Minimum of 30 minutes up to a maximum of 96 hours ]
- Efficacy: Percent change in SBP from baseline at each time point [ Time Frame: Every 1.5 minutes during the first 30 minutes of clevidipine infusion (approximately 20 measurements) ]
- Efficacy: Percent change from baseline in SBP [ Time Frame: At each hour after 30 minutes post-clevidipine infusion through termination of clevidipine infusion (up to a maximum of 96 measurements) ]
- Efficacy: Percent change from baseline in SBP over the first 8 hours post-study drug termination [ Time Frame: During the first 8 hours after termination of clevidipine infusion ]
- Efficacy: Percent change from baseline in heart rate [ Time Frame: During the first 30 minutes of clevidipine infusion ]
- Efficacy: Percent change from baseline in heart rate [ Time Frame: 30 minutes post-clevidipine infusion through termination of clevidipine infusion (minimum of <1 minute up to a maximum of 95 1/2 hours) ]
