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 Results may not be published yet.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.

This status has not been confirmed recently, so it may be out of date.

Summary

This phase I trial is testing a new radioactive tracer called [18F]FTT, which is used with PET/CT scans to find tumor cells in people with solid tumors, including breast, ovarian, and other cancers. The study will enroll 300 participants and aims to see how well the tracer highlights cancer cells compared to standard imaging. It is not a treatment but a way to improve cancer detection.

What this could mean

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

Active substance
Fluorine F 18 Fluorthanatrace ([18F]FTT)
What this could lead to
If successful, this imaging method could help doctors better detect and monitor certain cancers, like ovarian or breast cancer, by highlighting tumor cells more clearly.
What could go wrong
This is an early phase I study focused on imaging, not treatment. The tracer may not work as hoped, and results may not apply to all patients or cancer types.

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

Inclusion Criteria: * History of known or suspected solid tumor. * At least one lesion ≥ 1.0 cm that is seen on standard imaging (e.g. computed tomography \[CT\], magnetic resonance imaging \[MRI\], ultrasound, fludeoxyglucose \[FDG\] PET/CT). Exclusion Criteria: * Females who are pregnant or breast feeding at the time of screening will not be eligible for this study; a urine pregnancy test will be performed in women of child-bearing potential \< 2 weeks prior to screening as standard of care. * Inability to tolerate imaging procedures in the opinion of an investigator or treating physician. * Any current medical condition, illness, or disorder as assessed by medical record review and/or self-reported that is considered by a physician investigator to be a condition that could compromise participant safety or successful participation in the study.
