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

Summary

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.

Interventions

• Diagnostic Test
  68Ga-DOTA-TATE PET Scan

  68Ga-DOTATATE is administered via intravenous injection of 5 1 mCi in a volume of 3 - 5 ml containing up to 50 micrograms \[68Ga\] DOTATATE.

• Other
  Amino acid infusions

  Appropriate amino acid solutions infused for this purpose should have a total lysine and arginine content between 18g and 25g and have an osmolality of \<= 1050 mOsmol. Concomitant administration of an amino acid infusion with the study drug 177Lu-DOTA-EB-TATE is for renal protection.

• Drug
  177Lu-DOTA-EB-TATE

  Each single-dose vial contains sodium acetate (24.6 mg/mL), gentisic acid (3.7 mg/mL), L-ascorbate (0.445 mg/mL), DTPA (0.051 mg/mL). 177Lu-DOTA-EB-TATE, is a long-acting radiopharmaceutical for PRRT. It consists of a somatostatin analog peptide (TATE) conjugated with a truncated Evans blue (EB) molecule and the metal chelator 1,4,7,10-tetraazacyclodecane-1,4,7,10-tetraacetic acid (DOTA) with the radioisotope 177Lu stably complexed.
