18F-Floretyrosine Expanded Access Program

NO_LONGER_AVAILABLE

Conditions studied: Glioma (Any Grade) in the Brain

In brief

The aim of this Expanded Access Program (EAP) is to enable the use of 18F-Floretyrosine with positron emission tomography/computed tomography (PET/CT) or positron emission tomography/magnetic resonance (PET/MR) imaging to noninvasively detect tumor burden or treatment related change to assist in optimal management of patients with glioma.

Who can join

Age: 3 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Written and voluntarily given informed consent. Pediatric patients (<18 years of age) will provide assent along with parental/legal guardian /caregiver consent according to IRB requirements.
• Male or female ≥ 3 years of age at time of consent/assent
• Diagnosis or clinical suspicion of glioma (any grade) in the brain
• At the time of screening have undergone therapy for glioma
• Indeterminate MR findings for disease recurrence or progression versus treatment related changes (pseudoprogression or pseudoresponse) requiring further diagnostic procedures within 60 days prior to the 18F-Floretyrosine PET imaging
• Willing and able to lie still for at least 40 minutes in an enclosed space for the imaging procedure, or if medically necessary, able to tolerate standard institutions procedures for sedation and/or anesthesia.

You may not qualify if…

• Participant cannot be safely scanned due to devices, implants, foreign and/or metallic objects in or on the body that are not MR compatible, unless a clinical judgement is made that the participant's diagnostic needs can instead be met by diversion to 18F-Floretyrosine imaging by PET/CT (making the magnetic field compatibility an irrelevant safety concern).
• Women who are pregnant or breastfeeding.
• Women of childbearing potential who are unwilling or unable to use an acceptable method of contraception to avoid pregnancy for the duration of the program (Day 0 to Day 2).
• Serious non-malignant disease (e.g., psychiatric, infectious, autoimmune, or metabolic), that may interfere with the objectives of the program or with the safety or compliance of the participant, as judged by the Investigator.
• Mental impairment that may compromise the ability to give informed consent/assent and comply with the requirements of the program as judged by the Investigator.
• Exposure to any experimental diagnostic or therapeutic drug within 30 days from the date planned administration of 18F-Floretyrosine.
• Known hypersensitivity to floretyrosine or tyrosine derivatives.
• Unable to tolerate the program procedures.
