NCT ID NCT05553041

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 Results may not be published yet.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

Summary

This study tests whether a special PET scan called 18F-Fluciclovine can help doctors tell the difference between actual tumor growth and harmless changes caused by treatment in children with high-grade glioma. About 30 children aged 1 to 21 will receive the scan after radiation therapy. The goal is to improve diagnosis and avoid unnecessary procedures.

Inclusion Criteria * 1\. Histopathology-proven HGG (WHO grade III-IV) or DMG (WHO grade IV) or, in the case of DMG of the pons, imaging that is characteristic of Diffuse intrinsic pontine gliomas (DIPG) (diffusely infiltrating \>=2/3 of the pons). * 2\. Measurable disease, measuring at least 1x1 cm. * 3\. Life expectancy of greater than 8 weeks. * 4\. Age \> 1 years but \< 21 years of age at enrollment. For those without planned surgery: * 1\. Participants with clinical and/or radiographic suspicion of True progression (TP) or Pseudoprogression (PsP) during radiation but yet to have the initial post-radiation MRI scan. or * 2\. Participants with suspicion for TP or PsP on first post-radiation MRI For those with planned surgery: * 1\. Clinical or radiographic suspicion of tumor progression with plan to undergo surgery or biopsy. Exclusion Criteria: * 1\. Inability to tolerate imaging procedures in the opinion of an investigator or treating physician. * 2\. Pregnant or breastfeeding participants. * 3\. Participant who would require sedation or anesthesia for imaging beyond standard of care (SOC). * 4\. Participants who weigh less than 8 kg. * 5\. Participants who cannot avoid contact with a pregnant woman or infant for at least 12 hours following injection. * 6\. Participants with a history of abnormal kidney function or creatinine \>= CTCAE v5.0 grade 2 at time of study registration. 7\. Participants with primary tumors of the spinal cord.
