Gallium-68 NODAGA-JR11 PECT/CT in Neuroendocrine Tumors

September 15, 2023 updated by: Weibing Miao, PhD, First Affiliated Hospital of Fujian Medical University

A Prospective Study to Evaluate the Lesion Detection Ability of Gallium-68 NODAGA-JR11 for the Diagnostic Imaging of Metastatic, Well-differentiated Neuroendocrine Tumors Using PET/CT

NODAGA-JR11 is a novel somatostatin receptor antagonist, while Gallium-68 DOTATATE is a typical somatostatin receptor agonist. This study is to evaluate the lesion detection ability of Gallium-68 NODAGA-JR11 for the diagnostic imaging of metastatic, well-differentiated neuroendocrine tumors using positron emission tomography / computed tomography (PET/CT).

The results will be compared between antagonist Gallium-68 NODAGA-JR11 and agonist Gallium-68 DOTATATE in the same group of patients.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Patients with histologically confirmed metastatic, well-differentiated neuroendocrine tumors will be recruited in this study.

Each patient received an intravenous injection of 68Ga-DOTATATE (40ug/150-200MBq) on the first day and 68Ga-NODAGA-JR11 (40ug/150-200MBq) on the second day. Whole-body PET/CT scans were performed at 40-60 min after injection on the same scanner. Physiologic normal-organ uptake, lesion numbers, and lesion uptake were compared.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • • Written informed consent.

    • Patients of either gender, aged ≥ 18 years.
    • Histologically confirmed diagnosis of Metastatic, well-differentiated neuroendocrine tumor.
    • A diagnostic computed tomography (CT) or magnetic resonance imaging (MRI) of the tumor region within the previous 6 months prior to dosing day is available.
    • At least 1 measurable lesion based on RECIST v1.1.

    • Blood test results as follows (White blood cell: ≥ 3*10^9/L, Hemoglobin:

      ≥ 8.0 g/dL, Platelets: ≥ 50x10^9/L, Alanine aminotransferase / Aspartate aminotransferase / Alkaline phosphatase: ≤ 5 times upper limit od normal (ULN), Bilirubin: ≤ 3 times ULN)

    • Serum creatinine: within normal limits or < 120 μmol/L for patients aged 60 years or older.
    • Calculated Glomerular filtration rate (GFR) ≥ 45 mL/min.

Exclusion Criteria:

  • • Known hypersensitivity to Gallium-68, to NODAGA, to JR11, to TATE or to any of the excipients of Gallium-68 NODAGA-JR11 or Gallium-68 DOTATATE.

    • Presence of active infection at screening or history of serious infection within the previous 6 weeks.
    • Therapeutic use of any somatostatin analog, including long-acting Sandostatin (within 28 days) and short-acting Sandostatin (within 2 days) prior to study imaging. If a patient is on long-acting Sandostatina, then a wash-out phase of 28 days is required before the injection of the study drug. If a patient is on short-acting Sandostatin, then a wash-out phase of 2 days is required before the injection of the study drug.
    • Any neuroendocrine tumor-specific treatment between antagonist and agonist scans.
    • Prior or planned administration of a radiopharmaceutical within 8 half-lives of the radionuclide used on such radiopharmaceutical including at any time during the current study.
