About this study

Official title: MINI-AMI: Minimizing INfarct Size With IMPELLA® 2.5 System Following PCI for Acute Myocardial Infarction

A prospective, randomized, controlled multi-site feasibility trial to assess the potential role of the IMPELLA® 2.5 System in reducing infarct size in patients with ST-elevation myocardial infarction (STEMI)

Read the detailed description

The primary objective of this study is to evaluate whether the adjunctive use of the IMPELLA® 2.5 System for 24 hours following primary PCI for STEMI has the potential to limit the infarction of at-risk myocardium compared to primary PCI with routine post-PCI care (standard of care). This study is a feasibility study. Therefore, the principal objective is to identify trends in cardiac magnetic resonance imaging (MRI)-based efficacy outcomes between the randomized treatment arms (Impella arm compared standard of care.

What participants receive

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

  • Impella 2.5 supportDevice

    Also called Impella LP 2.5

    Patients enrolled in the Impella arm will receive 24 hours of post-PCI hemodynamic support using the Impella 2.5

  • Standard of care (Control)Other

    Standard care for STEMI patients post-PCI from ACC/AHA Guidelines

Study groups in NCT01319760
Study groupRoleWhat they receive
Standard of careSham comparatorPatients in the control arm will be treated with standard of care for post-PCI STEMI patients in accordance with the the 2004 ACC/AHA Guidelines for the Management of Patients with ST-elevation Myocardial Infarction.

What is being measured

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

  1. Infarct Size

    Infarct size (as assessed by cardiac MRI at 3-5 days following the infarction).

    Measured: 3-5 Days post infarct

  2. No Data for Primary or Secondary Enpoints Were Collected

    Measured: No data for primary or secondary enpoints were collected

Secondary outcomes (1)
  1. Infarct Size

    Assessment of infarct size and remodeling characteristics at 90 days post-infarct.

    Measured: 90 Days

Questions about this trial

What is this clinical trial studying?

A study testing Impella 2.5 support in people with ST-elevation Myocardial Infarction, run by Abiomed Inc..

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 6 inclusion and 19 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: stopped early, as of the sponsor's last update on 13 May 2019. Status can change between updates, so confirm with the study contact before making plans.

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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 13 May 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Infarct Size (time frame: 3-5 Days post infarct). The study lists 2 primary outcomes in all. 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 13 May 2019.
