PET/CT Imaging for Glioma
What You Need to Know Before You Apply
What is the purpose of this trial?
The goal of this clinical trial is to evaluate Positron emission tomography/computed tomography (PET/CT) imaging with the radiotracer 1-(2-\[18F\]fluoroethyl)-l-tryptophan (\[18F\]FETrp) in patients diagnosed with a glioma. This study has 3 aims:
* to assess if the \[18F\]FETrp PET/CT can outperform Magnetic Resonance Imaging (MRI) by providing a better treatment target volume in newly diagnosed Stage 4 glioma patients
* better differentiate tumor progression from radiation induced MRI changes in post treatment stage 4 gliomas
* by giving a drug that can inhibit a pathway to allow objective assessment of treatment effects in low grade gliomas

What Are the Treatments Tested in This Trial?
Interventions
- [18F]FETrp PET/CT
- Minocycline
Trial Overview
The study is testing a special PET/CT scan using the tracer [18F]FETrp to see if it gives better information than MRI in brain tumor patients. Some participants will also take minocycline, an antibiotic, to help assess its effects on imaging results.
How Is the Trial Designed?
3
Treatment groups
Experimental Treatment
Arm 3. Minocycline orally 200mg/day administered between the first \[18F\]FETrp PET scan and the month follow up \[18F\]FETrp scan to determine if pharmacologic inhibition of the kynurenine pathway will reduce tumoral tryptophan metabolic rates in low-grade gliomas
Arm 2. \[18F\]FETrp PET to differentiate post-treatment glioma progression from radiation-induced MRI changes
Arm 1. \[18F\]FETrp PET prior to radiotherapy in newly diagnosed grade 4 glioblastoma to provide a better treatment target volume
