177Lu-DOTA-EB-TATE in Adult Patients With Metastatic, Radioactive Iodine Non-Responsive Oncocytic (Hurthle-Cell) Thyroid Cancer
Phase 1/2, Open-Label Study of the Safety, Dosimetry and Efficacy of a 3-Dose Regimen of Escalating Doses of 177Lu-DOTA-EB-TATE in Adult Patients With Metastatic, Radioactive Iodine Non-Responsive Oncocytic (Hurthle-Cell) Thyroid Cancer
Source: ClinicalTrials.gov · Last updated 4 Nov 2026
Brief summary (registry, in English)
Background: Oncocytic (Hurthle cell) thyroid cancer (HTC) is a rare disease with few treatment options. Researchers are developing a radioactive drug that targets a protein that appears in high numbers on HTC cancer cells. Objective: To test a radioactive drug (177LuDOTA-EB-TATE) in people with HTC. Eligibility: People aged 18 years and older with HTC. The HTC must have failed to respond to conventional radioactive treatment; it must also have spread to other parts of the body. Design: Participants will be screened. They will have a physical exam with blood tests. They will have imaging scans and a test of their heart function. 177LuDOTA-EB-TATE is infused into a vein. Participants will receive 4 infusions spaced 8 to 12 weeks apart. They will stay in the hospital for 4 to 10 days after each infusion. During and after each infusion, participants will remain in a lead-lined room until their radiation levels go down; this usually takes about 24 hours. Participants will have 4 to 6 follow-up visits in the weeks after each infusion. Procedures will vary at each visit, but may include more imaging scans; blood and urine tests; and tests of heart function. Participants will have 2 single-photon emission computerized tomography (SPECT) scans. SPECT scans show where the study drug is sticking to tumors or maybe other parts of their body. They will lie on a table while a machine rotates around them. Participants will fill in questionnaires about how their thyroid condition affects their life. Participants will have follow-ups visits for 5 years after their last study treatment.

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- 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.
- Previous surgery \< 6 weeks prior to the start of participation in this study, or participant has not fully recovered from major surgery, or has suffered 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.
- Inability or unwillingness to use adequate contraception prior to study entry and for the duration of study participation, including follow-up (7 months after the last dose of study drug for women and 4 months for men). The adequate contraception consists of intrauterine device, contraceptive implant, hormonal contraception or a double-barrier method. If the patient is status post tubal ligation, status post hysterectomy and/or oophorectomy, or their male partners are status post vasectomy, no additional method of contraception is required.
- Patients who have had any prior EBRT dose to either kidney.
- Previous local therapy \<4 weeks prior to study entry.
- Prior external beam radiation therapy involving \>25% of the bone marrow.
Other illness
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to 177Lu-DOTA-EB-TATE as assessed from medical record.
- Active and clinically significant bacterial, fungal, or viral infection, including hepatitis B (HBV), hepatitis C (HCV), known human immunodeficiency virus (HIV), or acquired immunodeficiency syndrome (AIDS)-related illness. Radiolabeled ligands may affect the immune response, so people with active and clinically significant infections may become too immunocompromised through participation in this study.
- 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.
- 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.
Lab values
- Deteriorated renal function, as indicated by a creatinine clearance \<60 mL/min calculated by the Cockcroft-Gault Equation. The calculated creatinine clearance can be confirmed by measured creatinine clearance.
- Deteriorated bone marrow function, as indicated by:
- Hemoglobin (Hb) \< 8.0 g/dL
- White blood cell (WBC) \< 2 x10\^3/uL
- Absolute neutrophil count (ANC) \< 1.0 x 10\^3/L
- Platelets \<100 x 10\^3/microL
- Deteriorated liver function, as indicated by one or more of the following:
- International normalized ratio (INR) \> 2.0 for patients that are not on Coumadin
- Prothrombin time (PTT) \> 2 x ULN
- Total bilirubin \> 3 mg/dL
- Serum albumin \< 3.0 g/dL unless prothrombin time is within the normal range
- Alanine aminotransferase (ALT) \> 3 x ULN
- Aspartate aminotransferase (AST) \> 3 x ULN.
- Extended QTc interval above 480 ms confirmed by 2 ECGs. If the first ECG conducted at the screening visit shows extended QTc interval, potential participants will be asked to repeat an ECG within 30 days to confirm. The second ECG can be conducted at NIH CC or at their outside provider, at their potential expense.
- Toxicities from prior therapies that have not resolved to grade 1 or grade 0 excluding dry mouth syndrome from previous RAI and grade 2 anemia/leukopenia as Hgb\>=8 g/dl, WBC \>=2 x10\^3/uL and ANC \>= 1.0 x 10\^3 are acceptable for enrollment.
Other
- An individual who meets any of the following criteria will be excluded from participation in this study:
- Pregnant or breastfeeding.
- NET/PET score of 5 by imaging with 68Ga-DOTATATE PET/CT and 18FDG-PET/CT and defined more than 2 lesions that are SSTR2 negative but 18FDG positive and/or more than 2 lesions that have significantly higher uptake of 18FDG than 68Ga-DOTATATE
- Patient weight \> 500 lbs. (due to the PET scanner table limit).
- Inability to tolerate at least one modality of diagnostic anatomic imaging, such as CT or MRI.
- Life expectancy \< 6 months as assessed by the treating physician.
- Karnofsky performance status scale \< 70%.
- Having only one functional kidney, due to potential nephrotoxicity.
- Known brain metastases and/or carcinomatous meningitis unless these metastases have been treated and stabilized.
- Unmanageable urinary incontinence rendering the administration of 177Lu-DOTA-EB-TATE unsafe.
- Is unwilling or unable to establish care with a local provider outside of NIH CC
- Inability to understand or unwilling to sign a written informed consent document.
