What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tested whether a special PET scan using 68Ga-DOTATOC can detect inflammation in the heart muscle of people with myocarditis. 33 adults with suspected acute myocarditis and normal angiograms received the scan. The goal was to see if this method is as good as or better than MRI at finding active inflammation, including long-lasting cases.

What this could mean

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

Active substance
68Ga-DOTATOC (a radioactive tracer for PET imaging)
What this could lead to
If successful, this imaging method could help doctors detect ongoing heart inflammation more accurately, especially in cases where MRI is unclear.
What could go wrong
This is a small pilot study with only 33 participants, so results may not apply to everyone. The tracer's sensitivity and specificity are still uncertain.

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

33 people

The number who actually took part.

Started

Jul 2020

Finished

Dec 2023

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.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

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: * Adult subjects who have given their written consent to participate in the study. * Patients without history of heart disease, hospitalized for acute infarction suspected with positive troponine, normal or subnormal angiography and which have a high probability of acute inflammatory myocardities on the secondarily realized MRI (= 2 criteria of Lake Louise) * No contraindication to perform a 68Ga-DOTATOC-PET . * Patient belong to a social security scheme. Exclusion Criteria: * Patients under guardianship or curatorship. * Pregnancy, breastfeeding and woman of childbearing age without effective contraception * Impossibility to perform a PET with 68Ga-DOTATOC (patient agitated). * Impossibility to schedule PET/CT before the deadline = in 7 days since the beginning of the hospitalization.
