Summary

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.

Detailed description

The trial will enroll competitively up to 21 patients per cohort. The study will enroll the first 12 patients within the cohort and monitor for response. If no confirmed response is documented the cohort will be closed. If there is one or more confirmed responses reported that cohort will be expanded up to the expected 21 patients. All patients, male or female, ≥ 18 years, with ECOG PS 0-1. Cohort 1 will include patients with advanced radioactive-iodine refractory DTC who progressed to previous TKIs (including but not limited to lenvatinib, sunitinib or cabozantinib) and cohort 2 will include patients with advanced or metastatic ATC who may be on first-line or progressed to a previous systemic treatment. Patients will have not received previously chemotherapy, biologics, investigational agents, and/or antitumor treatment with immunotherapy that are not completed 2 weeks before first dose of study treatment (See Section 6 for further detail on eligibility). All enrolled patients will receive sacituzumab govitecan (10 mg/kg intravenously) on Days 1 and 8 of a 21-day cycle. Patients will be treated until progression, death, study withdrawal, or unacceptable toxicity. Sacituzumab govitecan is administered intravenously as a slow infusion as described below. Dosing is based on the patient's body weight on Day 1 of each cycle (or at each dosing day if change in body weight is \>10% or if required by institutional policy). Sacituzumab govitecan at 10 mg/kg will be the highest assigned dose. Dose reductions and delays will be allowed. All patients will undergo periodic tumor assessments by CT or MRI scan every 12 weeks ± 14 days (3 months), and blood monitoring of tumor markers (i.e. thyroglobulin if applicable) every 12 weeks ± 3 days (3 months) from the start of study treatment until progression or patient withdrawal.
