PIONEER Trial:Hemodynamic Support With ECMO and IABP in Elective Complex High-risk PCI

August 4, 2019 updated by: Xijing Hospital

A Prospective, Multicenter, Randomized Clinical Trial of Hemodynamic Support With ECMO and IABP Versus IABP Alone, in Complex High-risk Patients Undergoing Elective PCI(PIONEER Trial)

To determine whether hemodynamic support combining VA-ECMO with IABP could mitigate the rates of Major Adverse Cardiovascular and Cerebrovascular Events (MACCEs), compared with IABP support alone, in patients undergoing elective and high-risk PCI.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Percutaneous Coronary Intervention (PCI) supported by mechanical circulatory device may be a viable alternative for these patients with complex coronary artery disease combined with multiple comorbidities and poor hemodynamics. Extracorporeal Membrane Oxygenation (ECMO) can direct blood flow out of the body, oxygenate it, and then return it, to either completely or partially replace the function of the heart and lungs, and potentially increase the likelihood of functional recovery. Limitations of ECMO include lack of direct LV unloading, and increased LV afterload with subsequent LV overload, which in turn can increase myocardial oxygen demand and therefore limit any cardioprotective benefits . Measures to concurrently decrease LV afterload during ECMO, such as use of an Intra-Aortic Balloon Pump (IABP), may in theory offset some of the disadvantages of ECMO. To date, ECMO has most commonly been used in patients suffering from cardiac arrest and cardiogenic shock . As far as we are aware, there exist very limited reported data from monocentric observational studies and individual case reports on the use of ECMO for elective, high-risk PCI in the literature . More importantly, no previous randomized studies to evaluate the safety and efficacy of a strategy combining VA-ECMO and IABP during high-risk PCI have been conducted to date. Most importantly, the strategy of combined VA-ECMO and IABP has never been investigated in any randomized trial that we could find.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
