68Ga-DOTA-TOC PET/CT in Imaging Participants With Neuroendocrine Tumors

• Status: Terminated
• Trial end date: 2021-02-05
• Target enrollment: 0
• Participant gender: All

Summary

This trial studies how well gallium Ga 68-edotreotide (68Ga-DOTA-TOC) positron emission tomography (PET)/computer tomography (CT) works in imaging participants with neuroendocrine tumors. 68Ga-DOTA-TOC is used as a tracer chemical during PET/CT scans. Diagnostic procedures, such as 68Ga-DOTA-TOC PET/CT, may help find and diagnose neuroendocrine tumors.

• Phase: Early Phase 1
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: M.D. Anderson Cancer Center
• Collaborator: National Cancer Institute (NCI)
• Treatments: Edotreotide; Octreotide

Criteria

Inclusion Criteria:

• Ability of the subject, or the legally authorized representative (LAR), if the patient is deemed by the treating physician to be cognitively impaired or questionably impaired in such a way that the ability of the patient to give informed consent is questionable, to understand, and the willingness to sign, a written informed consent

• All participants must meet one of the following:

• Patients diagnosed or suspected to have neuroendocrine tumors (NET), who require 111In-pentetreotide imaging for clinical indications

• Subjects with a high risk of NET because of familial predisposition, and also have clinical findings which require radiolabeled somatostatin imaging

• Other somatostatin-positive tumors for which 111In-pentetreotide has been used successfully, such as adult meningiomas

• Patients with suspected neuroendocrine tumor, unknown primary NET, metastatic NET, or other tumors, such as meningiomas, in whom the primary physician considers somatostatin imaging to be clinically indicated

• Other NET subjects, whether asymptomatic or symptomatic, sporadic or familial, such as Von Hippel-Lindau syndrome (VHL) and multiple endocrine neoplasia type 1 (MEN1), will also be included

Exclusion Criteria:

• Pregnant women are excluded from this study because the effects of 68Ga-DOTATOC in pregnancy are not known; exceptions may be granted only if the expected risk outweighs the benefit, in the clinical opinion of the attending physician. Pregnancy testing will follow MD Anderson procedure for diagnostic reagents. Self-reporting is used to assess pregnancy status. If the subject is unsure about her status, a urine or serum pregnancy test will be performed before inclusion

• Lactating women are excluded if patient is unwilling to suspend lactation for at least one day following the administration of 68Ga-DOTATOC to the mother, because of the unknown but potential risk for adverse events in nursing infants secondary to administration of the radionuclide to a lactating woman

• Subjects with known contraindications to the use of 111In-pentetreotide

• Known severe allergy or hypersensitivity to oral contrast precludes administration of oral contrast only

• Patients with a body weight of 400 pounds or more, or a body mass index (BMI) which precludes their entry into the bore of the PET/CT scanner, because of the resulting probable compromise in image quality with CT, PET/CT and magnetic resonance imaging (MRI)

• Any additional medical condition, serious intercurrent illness, or other extenuating circumstance that, in the opinion of the investigator may significantly interfere with study compliance
