Clevidipine in the Perioperative Treatment of Hypertension (ECLIPSE-NTG)

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to establish the safety of clevidipine in the treatment of perioperative hypertension. Approximately 500-900 patients with perioperative hypertension undergoing coronary artery bypass grafting (CABG), off-pump coronary artery bypass (OPCAB) or minimally invasive direct coronary artery bypass (MIDCAB) surgery and/or valve replacement/repair procedures were anticipated to be randomly assigned to one of two treatment groups: clevidipine or nitroglycerin.

Detailed Description
-----------------
The primary objective was to establish the safety of clevidipine in the treatment of perioperative hypertension, as assessed by comparing the incidences of death, stroke, MI and renal dysfunction in the clevidipine and nitroglycerin treatment groups from the initiation of study drug infusion through postoperative Day 30. Secondary objectives were to evaluate the efficacy of study drug, assessed by the blood pressure (BP) lowering effect, and additional safety variables.

Eligibility Criteria
-----------------
Prerandomization Inclusion Criteria: Provide written informed consent before initiation of any study related procedures. Be at least 18 years of age Be scheduled for Coronary Artery Bypass Grafting (CABG), Off Pump Coronary Artery Bypass (OPCAB), Minimally Invasive Direct Coronary Artery Bypass (MIDCAB) surgery, and/or valve replacement/repair surgery Prerandomization Exclusion Criteria: Women of child-bearing potential (unless they have a negative pregnancy test) Recent cerebrovascular accident (within 3 months before randomization) Known intolerance to calcium channel blockers Known or suspected hypersensitivity to nitroglycerin Allergy to soybean oil or egg lecithin (components of the lipid vehicle) Pre-existing permanent ventricular pacing Any other disease or condition, which, in the judgment of the investigator would place a patient at undue risk by being enrolled in the trial Participation in another therapeutic drug or therapeutic device trial within 30 days of starting study Postrandomization Inclusion Criteria: Determined to be hypertensive perioperatively as determined by the investigator

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: clevidipine<br>Clevidipine (0.5 mg/mL in 20% lipid emulsion) was initiated after insertion of an arterial line upon the occurrence of perioperative hypertension, as determined by the investigator, and was administered intravenously (IV) at an initial infusion rate of 0.4 μg/kg/min (non weight-based equivalent is 2 mg/h). Clevidipine was titrated to blood pressure lowering effect by doubling increments approximately every 90 seconds up to a maximum infusion rate of 3.2 μg/kg/min (16 mg/h). Infusion rates above 3.2 μg/kg/min were permitted up to the maximum infusion rate of 8.0 μg/kg/min. Treatment was maintained as long as was deemed clinically necessary or until discharge from the ICU. Infusion rates between 4.4 and 8.0 μg/kg/min were to be administered for no more than 2 hours. | Drug: clevidipine<br> <br> * Other names: clevidipine, Cleviprex;|
| Active Comparator: nitroglycerin<br>Nitroglycerin (NTG) was initiated after insertion of an arterial line upon the occurrence of perioperative hypertension, as determined by the investigator, and was administered intravenously as per institutional practice. Treatment was maintained as long as was deemed clinically necessary or until discharge from the ICU. | Drug: nitroglycerin<br> <br> |
