About
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.
Full description
Study Description:
The proposed indication is for the treatment of somatostatin receptor-positive radioactive iodine (RAI) non-responsive metastatic oncocytic (Hurthle cell) thyroid (HTC) cancer in adults. We hypothesize that this study will address the following:
- Evaluate if 177Lu-DOTA-EB-TATE is safe and tolerable.
- Analyse early efficacy of 177Lu-DOTA-EB-TATE in metastatic HTC.
- Establish the optimal dose of 177Lu-DOTA-EB-TATE that is characterized by an optimal trade-off between efficacy and toxicity based on Bayesian optimal interval phase I/II time-to-event (TITE-BOIN12).
Objectives:
Primary Objectives:
- To determine the optimal dose of 177Lu-DOTA-EB-TATE that is both safe and shows sufficient efficacy for treatment of metastatic HTC based on TITE-BOIN12 design of phase 1/2 clinical trial.
- To identify the dose-limiting toxicities (DLTs) of escalating doses of 177Lu-DOTA-EB-TATE based on individualized dosimetry.
- To assess the efficacy of 177Lu-DOTA-EB-TATE to improve upon progression-free survival (PFS) at 6 months after the last cycle of the study drug in participants with metastatic RAI-non-responsive HTC.
Secondary Objectives:
- To determine dosimetry in patients following each cycle of 177Lu-DOTA-EB-TATE
- To assess the objective response rate (ORR) and disease control rate (DCR) and association between the specific absorbed dose per lesion of 177Lu-DOTA-EB-TATE.
- To assess the association between the specific absorbed dose per lesion with the tumor response as defined by RECIST 1.1 criteria.
- To assess changes in circulating levels of the tumor marker thyroglobulin (Tg) and anti-Tg antibodies throughout study participation.
- To assess the quality of life (QoL) throughout administration of 177Lu-DOTA-EB-TATE cycles.
- To capture extended safety data by assessing the rate of late adverse events (AEs) and serious adverse events (SAEs).
Endpoints:
Primary Endpoints:
- The primary safety endpoint is a combination of serious adverse events (SAEs), and dose limiting toxicities (DLTs) using CTCAE v5.0. We will also assess the number of participants with treat-related adverse events.
- The primary efficacy endpoint is progression free survival (PFS) at 6 months after the last cycle, where progression is defined by RECIST 1.1 criteria.
- For determination of the optimal dose, each patient will be classified into one of four categories according to the presence or absence of toxicity and efficacy at 8-12 weeks after each cycle and at 6 months after the last cycle.
Secondary Endpoints:
- Radiation-absorbed doses following each cycle of study intervention, normalized to administered activity, including:
- Residence time of 177Lu-DOTA-EB-TATE in liver, spleen, kidneys, whole body and blood pool.
- Specific absorbed dose per organ (Gy/GBq) (using MIRD method as implemented in OLINDA/EXM).
- Cumulative absorbed organ doses (Gy).
- Bone Marrow dose using blood-based method.
- Standardized uptake value (SUV) normalized to lean body mass for maximum (SULmax) in discernible target lesions.
- SULmax in liver, spleen, kidneys, bone marrow and pituitary if visible.
- Tumor response documented as objective response rate (ORR) and disease control rate (DCR) assessed at 24 (+/-2 weeks) and 52 (+/-2 weeks), as well as 2, 3, 4, and 5 years (+/-3 months) after completion of all treatment cycles, as defined by RECIST 1.1 criteria.
- Association between ORR/DCR and tumor absorbed dose using Spearman rank correlation 24 (+/-2 weeks) and 52 (+/-2 weeks), as well as 2, 3, 4, and 5 years (+/-3 months) after last dose of study drug
- Change in thyroglobulin (Tg) and anti-Tg antibodies from baseline to 24 (+/-2 weeks) and 52 (+/-2 weeks) post last dose of the study drug.
- ThyPRO QoL scores at baseline, after each study drug cycle, and at 24 (+/-2 weeks) and 52 (+/-2 weeks) post last dose of the study drug.
- AEs and SAEs at 2, 3, 4, 5 years (+/-3 months) of follow up after last dose of study drug.

Inclusion and exclusion criteria
- INCLUSION CRITERIA:
In order to be eligible to participate in this study, an individual must meet all of the following criteria:
- Aged 18 years or older.
- Metastatic RAI-non-responsive and/or RAI-non-avid oncocytic (Hurthle cell) thyroid cancer.
- Progressive disease by RECIST 1.1 criteria, with or without symptoms within the last 12 months. This applies to patients with non-measurable disease by RECIST 1.1 criteria, who will be eligible if they have evidence of progression as defined by the development of new lesions within the last 12 months.
- High expression of SSTR2 in at least one metastatic lesion as documented by 68Ga-DOTATATE PET/CT with SUVmax > SUVmax of the liver consistent with Krenning score of >2 or SUVmax >= 13 based on scan performed within 12 weeks of anticipated enrollment.
EXCLUSION CRITERIA:
An individual who meets any of the following criteria will be excluded from participation in this study:
-
Pregnant or breastfeeding.

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.
