177Lu-DOTA-EB-TATE in Patients With Advanced Neuroendocrine Tumors

Study Purpose

This is an open-label, non-controlled, non-randomized study to investigate the long-lasting radiolabeled somatostatin analogue based peptide receptor radionuclide therapy and evaluation safety and dosimetry of 177Lu-DOTA-EB-TATE in patients with advanced metastatic neuroendocrine tumors. A single dose of 0.50GBq-0.70GBq (13.5-18.9 mCi) of 177Lu-DOTA-EB-TATE will be injected intravenously. and monitored at 2, 24, 72,120 and 168 hours post-injection with semiquantitative method based on quantitative single-photon emission computed tomography/computed tomography (SPECT/CT) performance.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 18 Years - 70 Years
Gender All
More Inclusion & Exclusion Criteria

Inclusion Criteria:

  • - Adults who had neuroendocrine tumors and had metastasized, that were with histologically confirmed, inoperable and had showed disease progression according to Response Evaluation Criteria in Solid Tumors [RECIST].

Target tumors were selected from CT, MRI, and 68Ga-DOTA-TATE PET/CT, with confirmed somatostatin receptor-expressing and at least one lesion has higher uptake than that of normal liver parenchyma on 68Ga-DOTA-TATE PET imaging within 1 weeks.

Exclusion Criteria:

  • - The exclusion criteria were a serum creatinine level of more than 150 μmol per liter, baseline measured GFR of less than 50 mL/min/1.73 m2, determined by 99mTc-DTPA renal function examination, a hemoglobin level of less than 8.0 g/dl, a white-cell count of less than 2.0× 109/L, a platelet count of less than 75 × 109/L, a total bilirubin level of more than 3 times the upper limit of the normal range and a serum albumin level of more than 3.0 g per deciliter, cardiac insufficiency including carcinoid heart valve disease, a severe allergy or hypersensitivity to radiographic contrast material, claustrophobia, and pregnancy or breastfeeding.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Neuroendocrine Tumors
Additional Details

Neuroendocrine tumors (NETs) are a heterogeneous group of neoplasms that can develop anywhere in the body and arise from neuroendocrine cells throughout the endocrine system. The most recent NCCN guidelines for unresectable and metastatic NET recommend somatostatin analogues as first-line treatment, but do not recommend a particular treatment sequence for the remaining therapies. Radiolabeled somatostatin analogue therapy, also known as peptide receptor radionuclide therapy has become a well-accepted treatment for patients with well to moderately differentiated unresectable or metastatic NETs and disease progression after first-line treatment. However, a major problem in the therapeutic use of 177Lu-Dotatate has been its short half-life and fast rate of clearance. This study was designed to investigate the safety, dosimetry and preliminary effects of a long-lasting radiolabeled somatostatin analogue 177Lu-DOTA-EB-TATE in patients with advanced metastatic neuroendocrine tumors.
