|Aortic Aneurysm Aortic Disease||Drug: clevidipine.||Phase 4|
This study will be a Phase IV, open label, non-randomized efficacy and safety pilot trial in patients with AAE and hypertension requiring parenteral antihypertensive therapy. For the purpose of this study hypertension is defined as SBP ≥120 mm Hg immediately prior to clevidipine administration.
Patients will be enrolled at the Methodist DeBakey Heart & Vascular Center in Houston, TX. Enrollment of approximately 30 patients is anticipated and enrollment will continue until this goal is met.
The study will include three separate periods: Screening Period, Treatment Period (up to 48 hours) and Follow-up Period (up to 7 days or hospital discharge, whichever occurs first) representing approximately a maximum of 7 days on study. Eligible patients will be enrolled to receive clevidipine IV antihypertensive treatment (study drug) in an open label manner.
Clevidipine will be infused at an initial rate of 2 mg/h (4 mL/hr) for the first 3 minutes. Thereafter, titration to higher infusion rates can be attempted as needed to obtain the target SBP goal < 120 mmHg. Titration to effect is to proceed by doubling the dose every 3 minutes, up to a maximum of 32 mg/h (64 mL/hr), until the SBP < 120 mmHg is attained.
If the desired BP lowering effect is not attained with study drug within 1 hour or not maintained thereafter, an alternative antihypertensive agent may be used, with or without stopping clevidipine IV antihypertensive infusion. The alternative agent should be used per institutional treatment practice. During the initial 1 hour of the treatment period, however, clevidipine IV antihypertensive treatment should be administered as monotherapy until 1 hour post initiation of study drug. The use of an alternative antihypertensive agent(s) is discouraged and limited to where medically necessary to maintain patient safety.
Clevidipine IV antihypertensive infusion may continue for a maximum of 48 hours. However, if medically warranted, clevidipine treatment may continue beyond 48 hours at the investigator's discretion.

Open label, non-randomized, pilot study
All subjects who provide consent for trial participation with an acute aortic emergency and elevated BP (systolic blood pressure [SBP] ≥120 mm Hg) requiring IV antihypertensive therapy for up to 48 hours will be administered an infusion of clevidipine to evaluate the efficacy and safety of the IV drug.
Clevidipine administered per IV infusion, starting dose of 2 mg/h (4 mL/hr) for 3 minutes & titrated to the desired BP lowering effect to SBP goal of < 120 mmHg, max infusion rate may not exceed 32 mg/h (64 mL/hr).
Other Name: CLEVIPREX® (clevidipine)
- The primary objective of this pilot study is to evaluate the efficacy of an IV infusion of clevidipine as an antihypertensive for BP lowering in patients with AAE and elevated BP. [ Time Frame: 1 Hour ]
- The secondary objectives of the study are to evaluate the safety of an IV infusion of clevidipine as an antihypertensive for BP lowering in patients with AAE and elevated BP. [ Time Frame: 48 Hours ]
