Clevidipine in the Treatment of Patients With Severe Hypertension (VELOCITY)
- Registration Number
- NCT00369837
- Lead Sponsor
- The Medicines Company
- Brief Summary
The purpose of this study was to determine the safety of clevidipine for treating severely elevated blood pressure, defined as systolic (SBP) \>180 mmHg and/or diastolic blood pressure (DBP) \>115 mmHg assessed on 2 successive occasions 15 minutes apart at baseline, in patients with or without major organ injury, particularly with respect to controlled dose adjustment to desired effect and prolonged continuous infusion. Enrollment of patients into the study was to continue until the target goal of 100 patients with at least 18 hours of continuous clevidipine treatment, including a minimum of 50 patients with acute or chronic end-organ injury, was met.

Group Intervention Description clevidipine clevidipine A patient-specific blood pressure target range (TR) of ≥20 mm Hg and ≤40 mm Hg SBP was prespecified by the investigator. Once established, clevidipine (0.5 mg/mL in 20% lipid emulsion) intravenous infusion was initiated at 2.0 mg/h and maintained for the first 3 minutes. Clevidipine was up-titrated, as tolerated by the patient, by doubling the dose every 3 minutes until the prespecified systolic blood pressure (SBP) target range was achieved and could continue to be titrated up or down to maintain the desired long-term SBP reduction.
- Primary Outcome Measures
Name Time Method Percentage of patients in whom SBP falls below the lower limit of the patient-specific, pre-determined blood pressure target range at the initial dose (2.0 mg/h) Study drug initiation through the first 3 minutes of the infusion Percentage of patients who reach the prespecified target SBP range Within 30 minutes of the initiation of the infusion
- Secondary Outcome Measures
Name Time Method Time to attainment of the 30-minute SBP target range During the 30-minute period from initiation of infusion Change in heart rate During the 30-minute period from initiation of infusion Mean and median dose of clevidipine during the treatment period Treatment period is from initiation of infusion until study drug termination (minimum of 18 hours up to a maximum of 96 hours) Proportion of patients transitioning to oral antihypertensive therapy Within 6 hours of stopping study drug infusion Safety of clevidipine infusion for 18 hours or longer Treatment period is from initiation of infusion until study drug termination (minimum of 18 hours up to a maximum of 96 hours)
