What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether adding an intra-aortic balloon pump (IABP) to standard ECMO support helps more people with severe cardiogenic shock recover enough to come off the heart-lung machine. About 430 adults will be randomly assigned to get ECMO alone or ECMO plus IABP. The main goal is to see who can be weaned from ECMO within 30 days without needing a heart transplant or permanent heart pump.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Intra-aortic balloon pump (IABP)
What this could lead to
If it works, this could show that adding an IABP helps more patients successfully come off ECMO without needing a heart transplant or long-term heart pump.
What could go wrong
This is an early-stage platform trial, so results may not be definitive. The IABP itself carries risks like bleeding or vessel damage, and the benefit over ECMO alone is unproven.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 430 people

The number the study aims to enrol. It can still change while the study runs.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion criteria for the registry backbone: * Having received ECMO support for severe circulatory and/or respiratory insufficiency Inclusion Criteria for the LV unloading trial domain (VA ECMO + IABP vs VA ECMO alone): * Cardiogenic shock * Having received VA ECMO support for severe circulatory (and respiratory insufficiency). * Age ≥ 18 years * Initiation of LV unloading (IABP or Impella) possible ≤ 8 hours after ECMO initiation Exclusion criteria for the registry backbone * Objection to participation in the registry by the patient and/or proxy * VA ECMO usage confined to the period during surgery or another intervention (the VA ECMO was removed at the end of the intervention in the operation room). Exclusion criteria for the LV unloading trial domain (VA ECMO + IABP vs VA ECMO alone) * No (deferred) informed consent provided by the patient and/or proxy. * Pregnancy * ECMO usage confined to the period during surgery or another intervention (the ECMO was removed at the end of the intervention). * Isolated right ventricular failure (e.g. due to pulmonary embolism). * Left ventricular assist device (LVAD), Impella or IABP in situ. * Ventricular septal defect or papillary muscle rupture as the cause of shock. * Thoracic or abdominal aortic dissection. * Moderate or severe aortic regurgitation * Mechanical prosthesis in mitral valve position
