This is a single-arm, open-label, multicenter study designed to evaluate the preliminary antineoplastic activity, safety and tolerability of HA121-28 tablets administered orally in patients with medullary thyroid cancer (MTC).


A total of approximately 30 patients with MTC will be enrolled. The patients will undergo a 3 weeks-on and 1week-off treatment scheme with HA121-28 tablets 450 mg orally once daily in the 28-day cycle until disease progression or intolerable toxic reaction, whichever occurs first. During the administration of HA121-28 tablets, vital signs, physical examination, ECOG performance status, hematology and chemistry test, ECG, adverse events and concomitant drugs will be evaluated every four weeks, an additional ECG will be observed two weeks after the first dose, calcitonin and pregnancy test will be performed every 8 weeks. CT for tumor assessment will be performed every 8 weeks for the first year, and every 12 weeks thereafter.
