About this trial
SETHY is a prospective, multicohort, phase II, single-arm, non-randomized, non-blinded, investigator-initiated study of sacituzumab govitecan in patients with advanced or metastatic radioactive-iodine refractory differentiated thyroid carcinoma (DTC) or anaplastic thyroid carcinoma (ATC).
The main hypothesis is that treatment with sacituzumab govitecan, a anti-Trophoblast cell surface antigen 2 (TROP-2), could be an effective treatment option for patients with either differentiated and anaplastic thyroid neoplasms because TROP-2 is highly expressed at the membrane of DTC and ATC.
Eligibility criteria
Qualifiers
Institutional Review Board (IRB)/Independent Ethics Committee (IEC) approved written informed consent.
Patient is ≥ 18 years of age.
Patient has histologically confirmed metastatic or locally advanced unresectable radioactive-iodine refractory differentiated thyroid cancer (cohort A) or anaplastic thyroid carcinoma (cohort B).
Cohort A: Patients must have experienced progression on at least one previous treatment line with approved systemic therapies (Sorafenib, Lenvatinib or Cabozantinib) and a maximum of 3 prior systemic therapies.
Disqualifiers
Patient has central nervous system (CNS) metastases.
Patient has ongoing clinically significant toxicity (Grade 2 or higher with the exception of alopecia) associated with prior treatment (including systemic therapy, radiotherapy or surgery).
Patient has a history of another malignancy within 3 years before the first dose of study drug, or any evidence of residual disease from a previously diagnosed malignancy.
Patients who test positive for hepatitis B surface antigen (HBsAg). Patients who test positive for hepatitis B core antibody (anti-HBc) will require HBV DNA by quantitative polymerase chain reaction (PCR) for confirmation of active disease.
