This is a multicenter, single-arm, non-blinded dose titration efficacy and safety trial evaluating the ability of clevidipine, a vascular-selective L-type calcium channel antagonist, to rapidly control acute hypertension in patients with intracerebral hemorrhage. Informed consent will be obtained from patients meeting the inclusion criteria before the initiation of any study-specific procedures. At screening a clinical and neurological examination will be carried out. For the purposes of this study, acute hypertension will be defined as SBP >160 mmHg immediately prior to initiation of study drug. Approximately 30 to 40 patients with acute ICH will be enrolled with 10 patients requiring ICP monitoring. Infusion of study drug will be initiated within 12 hours of ICH symptom onset. All eligible patients will be enrolled to receive clevidipine in an open label manner. Clevidipine will be infused at an initial rate of 2.0 mg/h for the first 1.5 minutes. Thereafter, titration to higher infusion rates can be attempted as needed to obtain the target SBP range (SBP ≤160 mmHg to ≥140 mmHg). Titration to effect is 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) is attained. Clevidipine infusion may continue for up to a maximum of 96 hours. Twenty-four hour follow-up CT scan results will be recorded, including measurement of intracerebral hematoma volumes. Assessment of safety will be performed throughout the treatment period and until 6 hours after termination of study drug. Patients will be followed for 7 days following termination of the clevidipine infusion.
