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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 a new MRI contrast agent called Elucirem can detect heart scarring as effectively as the standard agent, but at a much lower dose. Researchers will compare images from 25 adults who previously had a heart MRI with the standard agent. If Elucirem works well at half the usual dose, it could mean less contrast agent exposure for patients.

What this could mean

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

Active substance
Elucirem (Gadopiclenol)
What this could lead to
If successful, this could allow doctors to use a lower dose of contrast agent for heart MRI, potentially reducing risks while still accurately detecting heart scarring.
What could go wrong
This is a very small, early-phase study with only 25 participants. The new agent may not perform as well as the standard one at lower doses, and results may not apply to all patients.

Show the full entry requirements

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

Inclusion Criteria: * Participants from previous double-dose Doatrem CMR study who are willing to participate and sign the consent will be enrolled in this study. Participants must be ≥21 years old, less than 120kg, not claustrophobic, and eGFR be 60 and more. Exclusion Criteria: * Participants under 21 years old will be excluded. Contraindications or limitations to contrast-enhanced MRI such as self-report of kidney disease, including kidney transplant or kidney surgery, eGFR less than 60, Metal fragments in eyes, brain, or spinal cord, Internal electrical devices such as cochlear implant, spinal cord stimulator, pacemaker, or defibrillator, pregnancy, allergic reaction to gadolinium in the past, claustrophobia, and cardiogenic shock or unstable condition that cannot tolerate the MRI scan will be excluded.
