177Lu-DOTA-EB-TATE in Adult Patients With Advanced, Well- Differentiated Neuroendocrine Tumors

Study Purpose

This is a Phase I clinical trial to assess the safety and dosimetry profiles of 177Lu-DOTA-EB-TATE in patients with advanced, metastatic or inoperable, somatostatin receptor-positive, well-differentiated GEP-NETs.

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 and Over

Previous treatment with more than 4 cycles of 177Lu-DOTA-TATE. Participant has had prior chemotherapy, targeted cancer therapy, immunotherapy, or treatment with an investigational anticancer agent within 4 weeks or 4 half-lives whichever is longer, before the first administration of study drug. Participant has not fully recovered from major surgery or significant traumatic injury prior the first dose of study drug or expects to have major surgery during the study period or within 3 months after the last dose of study drug. Life expectancy < 6 months as assessed by the treating physician. > 80% liver involvement by tumor. > 25% bone marrow involvement by tumor. Poorly differentiated neuroendocrine neoplasms, such as poorly differentiated neuroendocrine carcinoma, small- and large-cell neuroendocrine carcinoma; mixed neuroendocrine-non-neuroendocrine neoplasm (MiNEN); Grade 3 neuroendocrine carcinomas (NEC) Presence of somatostatin receptor negative lesions if they cannot be addressed with loco-regional therapies prior to the treatment start. Deteriorated renal function, as indicated by a serum creatinine clearance > 1.7 mg/dL. Deteriorated bone marrow function. Deteriorated liver function. Toxicities from prior therapies that have not resolved to grade 1 or grade 0. Active and clinically significant bacterial, fungal, or viral infection, including hepatitis B (HBV), hepatitis C (HBC), know human immunodeficiency virus (HIV), or acquired immunodeficiency syndrome (AIDS)-related illness.

The use of somatostatin and its analogues within 4 months of a planned 177Lu-DOTA-EB-TATE treatment. Uncontrolled, intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements. Prior external beam radiation therapy involving >25% of the bone marrow. Unmanageable urinary incontinence rendering the administration of 177Lu-DOTA-EB-TATE unsafe. Other known co-existing malignancies except non-melanoma skin cancer and carcinoma in situ of the uterine cervix, unless definitively treated and with no evidence of recurrence

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.

Arms & Interventions


Experimental: Peptide Receptor Radionucleotide Therapy (PRRT)

The treatment regimen will consist of a single-dose intravenous administration of 177Lu-DOTA-EB-TATE per 6-week cycle, for a total of 2 cycles. The dose per cycle will be fixed for each patient and will be escalated in 3 different dose levels, from 50 mCi to 150 mCi (1.85 -5.55 GBq). Each dose of 177Lu-DOTA-EB-TATE will be administered in association with intravenous renal protective amino acid solutions.


Drug: - 177Lu-DOTA-EB-TATE

Peptide Receptor Radionucleotide Therapy ( PRRT) using 177Lu-DOTA-EB-TATE with a defined number of cycles will be administered.

Other: - Amino Acid Solution

The Amino acid solution to be used in this study will contain a mixture of lysine and arginine diluted in an electrolyte solution.
