About this trial
To look at the effectiveness of zanzalintinib, followed by surgery, in treating advanced thyroid cancer. The safety of this treatment will also be studied.
Eligibility criteria
Qualifiers
Participants with differentiated thyroid cancer, non-RET-mutated medullary thyroid cancer, or poorly differentiated thyroid cancer who present with locoregionally advanced disease, as defined by extrathyroidal and/or extra nodal extension, or with advanced recurrent/residual invasive/bulky nodal disease will be enrolled in this trial, regardless of whether distant metastases are present or not.
At least 18 years of age on the day of signing informed consent.
Pathologic findings supporting the clinical impression of papillary thyroid cancer, follicular thyroid cancer, oncocytic thyroid cancer, medullary thyroid carcinoma, and/or poorly differentiated thyroid carcinoma. For patients with Bethesda IV or V FNA's (e.g. follicular neoplasm, follicular lesion, Hürthle cell neoplasm, Hürthle cell lesion), if the radiographic context is conclusive for carcinoma of thyroid origin, including significant extrathyroidal extension with invasion of surrounding structures and PET avidity, patients can be enrolled.
Thyroid Neck Group morbidity complexity score of 1 to 4 (moderate, severe, very severe, or unresectable).
Disqualifiers
Medullary thyroid cancer participants with germline RET or known somatic RET mutations.
Prior treatment with zanzalintinib.
Prior treatment with a tyrosine kinase inhibitor.
Receipt of any type of cytotoxic, biologic or other systemic anticancer therapy (including investigational) within 4 weeks before first dose of study treatment.
