Acute Heart Failure, Dyspnea, Hypertension
Conditions
Brief summary
The purpose of this study is to evaluate dyspnea improvement and other parameters of efficacy and safety in acute heart failure (AHF) patients receiving an intravenous (IV) infusion of clevidipine in comparison to standard of care (SOC) and placebo.
Detailed description
Randomization will occur in two stages. Stage 1 patients will be randomized in a double-blinded manner in a 1:1 ratio to receive either clevidipine or placebo IV infusion. Upon completion of Stage 1, Stage 2 patients will be randomized in an open-label manner in a 1:1 ratio to receive either clevidipine or standard of care (SOC) IV infusion. At the time of randomization, a patient-specific, prespecified systolic blood pressure (SBP) target range will be determined and recorded prior to study drug treatment. Up to 500 patients may be enrolled to achieve a total of 100 Stage 1 and 300 Stage 2 patients with confirmed AHF per protocol. A Data Safety Monitoring Board will be utilized periodically throughout the study to monitor the safety of patients. Adverse events will be assessed for 7 days post-study randomization or hospital discharge, whichever occurred sooner. Serious adverse events (SAEs) were assessed for 30 days following study randomization.
Interventions
Patients may be transitioned to an oral antihypertensive medication as necessary. When such a transition is required, then approximately 1 hour prior to the anticipated cessation of the double-blinded clevidipine infusion, an oral antihypertensive agent may be administered. The clevidipine infusion may be down-titrated or terminated at any time following administration of the oral agent, in order to achieve the desired BP level.

Transition to oral antihypertensive medication from SOC IV antihypertensive is per institutional practice.
