About this study

Official title: A Randomized Parallel Group Controlled Comparison Study of Clevidipine Versus Placebo or Standard of Care for Dyspnea and Blood Pressure Control in Acute Heart Failure (PRONTO II)

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.

Read the 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Stage 1: Clevidipine (double-blinded)Drug

    Also called Cleviprex, clevidipine

    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.

  • Stage 1: Placebo (double-blinded)Drug

    Also called Intralipid

    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 placebo infusion, an oral antihypertensive agent may be administered. The placebo infusion may be down-titrated or terminated at any time following administration of the oral agent, in order to achieve the desired BP level.

  • Stage 2: Clevidipine (open-label)Drug

    Also called Cleviprex, clevidipine

    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 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.

  • Stage 2: Standard of Care (open-label)Drug

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

Study groups in NCT04592380
Study groupRoleWhat they receive
Stage 1: Clevidipine (double-blinded)ExperimentalClevidipine (0.5 mg/mL in 20% lipid emulsion) will be administered in a double-blinded fashion intravenously to all patients randomized to the clevidipine arm in Stage 1. Clevidipine will be initiated at an initial rate of 2 mg/h for the first 1.5 minutes (90 seconds) and titrated thereafter per the Food and Drug Administration (FDA) approved clevidipine label, to achieve the target SBP +/- 5 mmHg. If the target SBP is achieved at any of the titration doses, that rate may be continued for up to 24 hours. If the desired BP lowering effect is not attained within 30 minutes or not maintained thereafter, any alternative antihypertensive agent may be used per institutional treatment practice, with or without stopping the study drug infusion.
Receives: Drug: Stage 1: Clevidipine (double-blinded)
Stage 1: Placebo (double-blinded)Placebo comparatorPlacebo will be administered in a double-blinded fashion intravenously to all patients randomized to the clevidipine arm in Stage 1. Placebo will be initiated at an initial rate of 2 mg/h for the first 1.5 minutes (90 seconds) and titrated thereafter according to the same dosing instructions as for clevidipine to achieve the target SBP +/- 5 mmHg. If the target SBP is achieved at any of the titration doses, that rate may be continued for up to 24 hours. If the desired BP lowering effect is not attained within 30 minutes or not maintained thereafter, any alternative antihypertensive agent may be used per institutional treatment practice, with or without stopping the study drug infusion.
Receives: Drug: Stage 1: Placebo (double-blinded)
Stage 2: Clevidipine (open-label)ExperimentalClevidipine (0.5 mg/mL in 20% lipid emulsion) will be administered in an open-label fashion intravenously to all patients randomized to the clevidipine arm in Stage 2, following the same dosing instructions as in the clevidipine arm in Stage 1. If the desired BP lowering effect is not attained within 30 minutes or not maintained thereafter, any alternative antihypertensive agent may be used per institutional treatment practice, with or without stopping the study drug infusion.
Receives: Drug: Stage 2: Clevidipine (open-label)
Stage 2: Standard of Care (open-label)Active comparatorFor patients randomized to SOC, the infusion must be continuous, administered per the institution's treatment practice, and dose titration must be performed to a maximum allowed or maximum tolerated dose to achieve target SBP. If treatment with an alternative IV anti-hypertensive agent is required, the patient will be transitioned to an alternative IV antihypertensive agent according to the institutional standard of care.
Receives: Drug: Stage 2: Standard of Care (open-label)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in dyspnea VAS score from baseline at 3 hours post-baseline

    Measured: Immediately prior to study drug administration (baseline) to 3 hours post-baseline

Secondary outcomes (2)
  1. Median time to reach target BP within the first 30 minutes

    Measured: Study drug initiation through the first 30 minutes of study drug infusion

  2. Percentage of patients who require rescue therapy (ie, receive any alternative IV antihypertensive drug) within the first 30 minutes

    Measured: Study drug initiation through the first 30 minutes of study drug infusion

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Stage 1: Clevidipine (double-blinded) and Stage 2: Clevidipine (open-label) in people with Dyspnea and Hypertension, run by The Medicines Company at 9 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 19 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in dyspnea VAS score from baseline at 3 hours post-baseline (time frame: Immediately prior to study drug administration (baseline) to 3 hours post-baseline). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Oct 2020.
