Summary

This trial studies a new scan to diagnose neuroendocrine tumors in children. The new scan, 68Ga-DOTATATE PET/CT, may work better than the standard of care MIBG scan.

Who is the study for?

This trial is for children and young adults up to age 30 with certain types of neuroendocrine tumors, including neuroblastoma, that have spread. They must be fit enough for radiation therapy and not pregnant or breastfeeding unless they agree to use birth control. Participants need to consent and commit to follow-up at the enrolling institution.

What is being tested?

The study tests a new scan called 68Ga-DOTATATE PET/CT in kids with metastatic neuroendocrine tumors. It checks if this radioactive tracer scan is better than current MIBG scans for diagnosis and helps target radiation treatment more effectively.

What are the potential side effects?

Since the intervention involves diagnostic imaging rather than medication, side effects are minimal but may include discomfort from the injection of the radiotracer or reactions related to lying still during scanning.

Treatment Details

Study Objectives

Study objectives can provide a clearer picture of what you can expect from a treatment.

Primary study objectives

Difference in radiation treatment target volume definition between 68Ga-DOTATATE positron emission tomography/computed tomography (PET/CT) and iobenguane (MIBG)

Secondary study objectives

Patterns of failure after RT

Proportion of agreement between MIBG and 68Ga-DOTATATE PET/CT in identifying neuroendocrine tumors

Tumor metabolic activity of 68Ga-DOTATATE PET/CT compared to MIBG

Awards & Highlights

All Individual Drugs Already Approved

Therapies where all constituent drugs have already been approved are likely to have better-understood side effect profiles.

No Placebo-Only Group

All patients enrolled in this study will receive some form of active treatment.

Trial Design

2Treatment groups

Experimental Treatment

Group I: Cohort B (68Ga-DOTATATE, PET/CT)Experimental Treatment3 Interventions

Patients with previously diagnosed high-risk neuroendocrine cancer receive 68Ga-DOTATATE IV and undergo PET/CT over 20-30 minutes at the time of radiation treatment planning.

Group II: Cohort A (68Ga-DOTATATE, PET/CT)Experimental Treatment3 Interventions

Patients with newly diagnosed high-risk neuroendocrine cancer receive 68Ga-DOTATATE intravenously (IV) and undergo PET/CT over 20-30 minutes at diagnosis (before any treatment) and at the time of radiation treatment planning.
