A Safety and Efficacy Study of Blood Pressure Control in Acute Heart Failure - A Pilot Study (PRONTO)

Clevidipine was to be administered continuously as monotherapy during the first 30 minutes. Use of an alternative IV antihypertensive agent(s) was discouraged and was limited to where medically necessary to maintain patient safety. Patients who received an alternative antihypertensive agent along with the study drug were allowed to continue in the study. If transition to an oral antihypertensive agent was required, it was to be administered approximately 1 hour prior to the termination of clevidipine with study drug down-titrated or terminated in order to maintain the desired blood pressure level.

SOC IV antihypertensive agent will be administered for a minimum of 30 min and, if medically warranted, may continue beyond 96 hours at the investigator's discretion. As with clevidipine, the SOC agent was to be administered continuously as monotherapy during the first 30 minutes. Use of an alternative agent(s) was discouraged and was limited to where medically necessary to maintain patient safety. Higher dose titration rates were required to be attempted prior to making the decision to switch to or add on an alternative antihypertensive agent(s). Patients who received an alternative antihypertensive agent with SOC were allowed to continue in the study. If transition to an oral antihypertensive agent was required, it was to be administered per institutional practice.
