Eligibility criteria
Qualifiers
Male/female participants who are at least 18 years of age on the day of signing informed consent with histologically confirmed diagnosis of differentiated thyroid carcinoma candidate to surgery not previously treated will be enrolled in this study.
Patients with a risk > 20% for persistent/recurrent disease: primary tumor > 4 cm; multifocal papillary microcarcinoma with extra tumor extension (ETE) and known BRAF V600E mutation; clinical N1; gross ETE (macroscopic invasion of perithyroidal soft tissues); extranodal extension; expected incomplete tumour resection.
Poorly differentiated carcinoma; Hurtle cell carcinoma.
Patients with distant metastasis at diagnosis.
Disqualifiers
A WOCBP who has a positive urine pregnancy test within 72 hours prior to randomization. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent or with an agent directed to another stimulatory or co-inhibitory T-cell receptor (eg, CTLA-4, OX-40, CD137).
Has received prior systemic anti-cancer therapy including investigational agents within 4 weeks prior to randomization.
Has received prior radiotherapy within 2 weeks of start of study intervention. Participants must have recovered from all radiation-related toxicities, not require corticosteroids, and not have had radiation pneumonitis. A 1-week washout is permitted for palliative radiation (≤2 weeks of radiotherapy) to non-CNS disease.
