Study summary

The purpose of this study is to see if 18F-Fluciclovine (Axumin®) is useful and safe in the management of children with Low Grade Gliomas (LGG). Imaging with 18F-Fluciclovine PET-MRI will be performed prior to initiation of therapy for LGG, and then 3 months, and 1 year after starting therapy. Changes in 18F-Fluciclovine uptake will be compared to changes in MRI measurements at 3 months and 1 year as compared to baseline.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. LGG including the brainstem and supratentorial only (WHO grade I-II), confirmed by unless in NF1 participants with classic appearance.
  2. Participants must have evaluable disease (1x1 cm tumor on MRI)
  3. Scheduled to receive systemic therapy for LGG
  4. Performance Score: ≥ 50 for participants > 16 years of age and Lansky ≥ 50 for participants ≤ 16 years of age. Participants who are unable to walk because of paralysis, but who are up in a wheelchair, will be considered ambulatory for the purpose of assessing the performance score.
  5. Age: Participants must be ≥ 1 years but ≤21 years of age at registration
  6. Being on a treatment regimen does not exclude a subject from enrollment.

Exclusion criteria

Exclusion Criteria

  1. Inability to tolerate imaging procedures in the opinion of an investigator or treating physician
  2. Pregnant participants
  3. Participants who weigh less than 8 kg.
  4. Participants who cannot avoid contact with a pregnant woman or infant for at least 12 hours following injection.
  5. Participants with a history of abnormal kidney function or creatinine >= v5.0 grade 2 at time of study registration.
  6. Participants with primary tumors of the spinal cord.
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Karnofsky performance status (KPS)

A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.

Studies often ask for 60 or 70 and above. Your doctor gives the score.

CTCAE grade

The US National Cancer Institute’s scale of how severe an adverse event is — any unwanted medical event during a study, such as a symptom, an illness or an abnormal test result, whether or not a treatment caused it. Whether it did is judged separately.

1
Mild.
2
Moderate.
3
Severe.
4
Life-threatening.
5
Death due to the event.

“Side effects of earlier treatment resolved to grade 1 or less” means they have settled to mild or gone.

What researchers measure

Primary outcomes

  1. Compare change in standardized uptake value parameters (SUVmax and SUVpeak) on metabolic tumor volume in 18F-Fluciclovine PET

    To identify change in the standardized uptake value (SUV) parameters (SUVmax, SUVpeak) for the 18F-Fluciclovine PET scan

    Time frame: 1 year

  2. Compare changes in pretreatment tumor measurement on MRI in pediatric participants who initiate systemic treatment for LGG

    Calculate the change in tumor measurement on MRI

    Time frame: 1 year

Secondary outcomes

  1. Safety of 18F-Fluciclovine

    The Safety profile of 18F-Fluciclovine PET in pediatric LGG participants will be accessed by the CTCAE 5.0 toxicity experienced after administration of 18F-Fluciclovine

    Time frame: 13 months

Other outcomes

  1. Response prediction

    Determine if Baseline PET uptake as predictors of treatment response

    Time frame: 1 year

  2. Disease Progression

    Identify changes in PET metrics at the time of progression

    Time frame: 1 year

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Nov 2026; primary completion for Dec 2027, 13 months later.

Of 166 non-industry phase 1 interventional studies under Glioma, half reached primary completion within 59 months of starting (the median), counting those still running; a quarter within 36 and three quarters within 87. This study's planned 13 months is below that.

Counting every sponsor, half of 213 studies reached it within 59 months; a quarter within 36 and three quarters within 88.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 22, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
