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

Paused
Paused for now. It may or may not start again.
Ongoing This study
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 Results may not be published yet.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

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.

Summary

This study tests a new radioactive tracer called 18F-DA for PET scans to see if it can find neuroblastoma and pheochromocytoma tumors more clearly than the current tracer. About 20 children and adults with known or suspected tumors will receive the tracer and be monitored for side effects. The goal is to see if 18F-DA is safe and could replace the current standard to improve tumor detection.

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

Inclusion Criteria: Patients with known or suspected neuroblastoma or pheochromocytoma are eligible. 18F-DA PET/CT scanning will not be the initial imaging study in a newly diagnosed patient. Patients with positive findings on prior imaging within the past 4 weeks are eligible. Prior therapy is allowed. Patients \> 1 year of age, under the care of a SJCRH physician. Patients of both genders, and all ethnic groups, under the care of a SJCRH physician. Female participants of childbearing age must not be lactating due to theoretical potential harm to the infant from exposure to radiation. Informed consent signed by participant, parent, or guardian according to the guidelines of the institutional review board. Patients may undergo a repeat study one or more years following the initial FLOPET scan. Exclusion Criteria: Inability or unwillingness of patient, parent, or guardian to consent. Pregnancy or lactation. Future plans for pregnancy do not exclude patient participation. Patients should not become pregnant within one month of completion of 18F-DA PET scan. Use of medications known to interfere with 123I-mIBG uptake (principal considerations are phenylephrine and pseudoephedrine containing compounds which need to be discontinued for 48 hours, and labetalol which needs to be discontinued for 6 weeks). Patients less than 3 years of age who require a total length of anesthesia time greater than 3 hours (for the FLOPET scan in conjunction with another clinical procedure requiring sedation) will be excluded from the study.
