Condition(s) targeted: Hypertension; Heart Failure

Intervention: Clevidipine (Drug); Standard of Care IV antihypertensive (Drug)

Phase: Phase 3

Status: Completed

Sponsored by: The Medicines Company

Official(s) and/or principal investigator(s):
W. Frank Peacock, MD, Principal Investigator, Affiliation: The Cleveland Clinic

Summary

The purpose of this study was to evaluate the efficacy and safety of intravenous (IV) clevidipine as compared with standard of care IV antihypertensive agents for blood pressure (BP) lowering in patients with acute heart failure and elevated BP.

Clinical Details

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

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome:

Time to First Achieve Initial Prespecified SBP Target Range and 15% Reduction From Baseline Within First 30 Minutes

Percentage to First Achieve Initial Prespecified SBP Target Range [≥20 mm Hg and ≤40 mm Hg Apart] and 15% Reduction From Baseline Within First 30 Minutes

Secondary outcome:

Percentage Reaching Prespecified Target Range Without Falling Below Lower Limit of Target Range Within First 30 Minutes

SBP Area Under the Curve (AUC) Outside Prespecified Target Range

Percentage Falling Below Lower Limit of SBP Target Range Within First 30 Minutes

Percentage Falling Below Lower Limit of SBP Target Range at Any Time During Study

Change From Baseline in Dyspnea (Measured By VAS) at Each Time Point

Time to Use Other IV Antihypertensives During the Study Drug Administration

Percentage of Patients Who Received Any Alternative IV Antihypertensive Drug at Any Time During Study Drug Treatment

Percentage of Patients With at Least One Episode of SBP < 90 mm Hg During Study Drug Administration (up to 96 Hours)

Number of Patients That Require Intubation During Study Drug Administration up to 96 Hours

Detailed description: This study was an open-label randomized efficacy and safety pilot trial in patients with acute heart failure (AHF) and hypertension (systolic blood pressure [SBP] ≥160 mm Hg) requiring parenteral antihypertensive therapy. Eligible patients were randomized to receive clevidipine or standard of care (SOC) intravenous antihypertensive treatment in an open-label manner in a ratio of 1: 1. At the time of randomization, a patient-specific, prespecified SBP target range was determined and be recorded, prior to study drug treatment. Information on the dosing regimen, use of additional or alternative agents and transition to oral therapy if needed is detailed in the study 'ARM' and 'INTERVENTION' sections. A Data Safety Monitoring Board was utilized periodically throughout the study to monitor the safety of patients. Adverse events were assessed for 7 days post-study randomization or hospital discharge, whichever occured first. Serious adverse events (SAEs) were assessed for 30 days following study randomization. Subjects were contacted by telephone or in person up to 5 days after their 30-day time point to determine if any SAEs occurred following study drug treatment and to follow up on the Heath Economic assessments.
