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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 is testing a special imaging agent called [13C]pyruvate to see how it behaves in healthy organs and tissues during MRI scans. Fifty healthy volunteers aged 18 to 80 will receive an injection of the agent, and researchers will measure image quality. The goal is to improve MRI technology for future disease detection.

What this could mean

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

Active substance
[13C]pyruvate (a special imaging agent for MRI scans)
What this could lead to
If successful, this study could help doctors get clearer MRI images, making it easier to spot diseases in organs and tissues.
What could go wrong
This is an early phase 1 study with only 50 healthy volunteers, so results may not apply to people with illnesses. The imaging agent is experimental and its safety in all situations is not yet fully known.

You do not need to have the condition being studied to take part.

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: Fifty healthy volunteers will be included. * Age between 18-80 * Negative serum or urine pregnancy test for female volunteers of childbearing age and potential (as defined by MSKCC Standards \& Guidelines), from assays obtained \<2 weeks prior to study enrollment. Urine pregnancy tests are only valid for the day of test. Exclusion Criteria: * Breast-feeding * History of metabolic (e.g. diabetes) and renal functional disorders. * Refusal or inability to tolerate the scanning procedure (e.g., due to claustrophobia) * Acute major illness (e.g., unstable cardiovascular condition, systemic malignant diseases, etc.). * Standard MRI safety screening will be applied (MRI screening questionnaire); volunteers with MR unsafe devices, or conditional devices where research mode is not allowed, will be excluded.
