GA-68 DOTA-TOC of Somatostatin Positive Malignancies (DOTA-TOC)

October 21, 2019 updated by: Thomas Hope, University of California, San Francisco

Evaluation of Gallium-68 DOTA-TOC Imaging of Somatostatin Receptor Positive Malignancies

This phase I/II trial studies how well gallium Ga 68-DOTA-TOC positron emission tomography (PET)/computed tomography (CT) or PET/magnetic resonance imaging (MRI) works in imaging patients with somatostatin receptor positive tumors. Gallium Ga 68-DOTA-TOC binds to somatostatin receptor positive tumors and can be seen using a PET scan. A PET scan uses a special camera to detect energy given off from gallium Ga 68-DOTA-TOC, to make detailed pictures of areas where material accumulates in the body. Diagnostic procedures, such as gallium Ga 68-DOTA-TOC PET/CT or PET/MRI, may help find and diagnose somatostatin receptor positive tumors and help plan the best treatment.

Study Overview

Detailed Description

PRIMARY OBJECTIVES:

I. To determine if gallium Ga 68-DOTA-TOC (gallium-68 labeled DOTA-TOC) results in the delineation of more lesions than with conventional imaging.

SECONDARY OBJECTIVES:

I. To determine if the incorporation of gallium (Ga)-68 DOTA-TOC PET/CT into the management decision making process results in a change in stage of the patient.

OUTLINE:

Patients receive gallium Ga 68-DOTA-TOC intravenously (IV) over 1-2 minutes. Within 55-70 minutes, patients then undergo a PET/CT scan over 30-40 minutes or a PET/MRI scan over 50 minutes.

After completion of study, patients are followed up for 2 weeks.

Description

Inclusion Criteria:

  • Known or suspected somatostatin receptor positive tumor such as carcinoid; neuroendocrine tumor; neuroblastoma; pheochromocytoma. Supporting evidence may include MRI, CT, biochemical markers, and or pathology report.
  • Age > 1.
  • Karnofsky performance status of > 50 (or Eastern Cooperative Oncology Group (ECOG) / World Health Organization (WHO) equivalent).
  • Not pregnant. A negative serum pregnancy test is required for all female subjects with childbearing potential.
  • Ability to understand a written informed consent document, and the willingness to sign it.

Exclusion Criteria:

  • Hepatic enzymes 5 times greater than the upper limits of normal, serum creatinine > 3.0 mg/dL (270 Micromole per liter (uM/L).
  • Patients exceeding the weight limitations of the scanner or are not able to enter the bore of the PET /CT scanner due to BMI
  • Inability to lie still for the entire imaging time (e.g. cough, severe arthritis, etc.); although at Mission Bay Hospital pediatric patients may be sedated per clinical protocol.
  • Inability to complete the needed investigational and standard-of-care imaging examinations due to other reasons (severe claustrophobia, radiation phobia, etc.).
  • Any additional medical condition, serious intercurrent illness, or other extenuating circumstance that, in the opinion of the Investigator, may significantly interfere with study compliance.
  • Recognized concurrent active infection Previous systemic or radiation treatment for another cancer of any type within the last 2 months.
  • Use of any other investigational product or device within 30 days prior to dosing, or known requirement for any other investigational agent prior to completion of all scheduled study assessments

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Lesions as Determined by Gallium Ga 68-DOTA-TOC Positron Emission Tomography (PET) Imaging
Time Frame: 1 day
The 5 largest lesions in each of eight body regions (head and neck, mediastinum, lung, liver, pancreas, the remaining abdomen and pelvis, bone and lymph nodes), will be measured by size (short and long axis) as well as standardized uptake value maximum on conventional imaging and the gallium Ga 68-DOTA-TOC PET imaging. Additionally, the confidence that each lesion represents a metastasis will be recorded The five largest lesions will be (1 = benign, 2 = likely benign, 3 = indeterminant, 4 = likely malignant, 5 = malignant). The number of positive body regions using conventional imaging and Ga-68 DOTA-TOC PET/CT will be compared using a paired t-test (or Wilcoxon signed-rank test if the data appear to be non-normally distributed). The Wilcoxon signed-rank test will also be used to compare reader confidence of paired lesions between conventional imaging and Ga-68 DOTA-TOC PET/CT
1 day
Standardized Uptake Value Maximum (SUVmax)
Time Frame: 1 day
The 5 largest lesions in each of eight body regions (head and neck, mediastinum, lung, liver, pancreas, the remaining abdomen and pelvis, bone and lymph nodes), will be measured by size (short and long axis) as well as standardized uptake value maximum on conventional imaging and the gallium Ga 68-DOTA-TOC PET imaging. Additionally, the confidence that each lesion represents a metastasis will be recorded.
1 day
Inter-reader Variability
Time Frame: 1 day
Inter-reader variability for the number of positive regions will be compared using Kappa statistics. In all cases we will provide point estimates and 95% confidence intervals for effects along with p-values.

Time Frame: Up to 2 weeks
Impact on care will be accessed for value added by the investigational Ga-68 DOTA-TOC PET/CT scan similar to assessment for impact on care as in the National Oncology PET registry. A percentage will then be calculated for both "Change in stage" with a 95% confidence interval determined.
