About this trial
This trial consists of 2 parts, i.e., Part Ia and Ib. The Part Ia is to evaluate the safety and tolerability of a single intravenous dose of af-001 in patients with radically unresectable, recurrent, metastatic differentiated thyroid cancer (papillary carcinoma, follicular carcinoma) refractory to or intolerant of standard-of-care therapy, who have received total thyroidectomy, and to determine the MTD (Maximum tolerated dose).
Part Ib is to evaluate the efficacy and safety of af-001 mutiple doses to patients with radically unresectable, recurrent, metastatic differentiated thyroid cancer (papillary carcinoma, follicular carcinoma), who have received total thyroidectomy and are RAI naïve, randomized into two arms at the determined MTD or the MTD-1 dose level, and to determine the recommended Phase II dose (RP2D)
