ARTICLE ABSTRACT

Medullary thyroid cancer (MTC) accounts for about 2% of all thyroid cancer, but has a relatively poor prognosis compared with differentiated thyroid cancer. Anlotinib is a novel multitarget tyrosine kinase inhibitor targeting VEGFR, PDGFR, FGFR, and c-Kit. This multicenter, randomized, double-blind, placebo-controlled phase IIB study (ALTER 01031 and NCT02586350) was conducted to investigate the efficacy and safety of anlotinib in MTC. Patients with histopathologically confirmed, unresectable locally advanced or metastatic MTC were enrolled and randomly assigned in a 2:1 ratio to receive anlotinib (12 mg once daily from day 1 to 14 every 3 weeks) or placebo. Patients in placebo group were allowed to receive open-label anlotinib after disease progression. The primary endpoint was progression-free survival (PFS); secondary endpoints included objective response rate (ORR), disease control rate (DCR), and overall survival (OS). Ninety-one patients were enrolled. At data cutoff date, the median PFS was significantly prolonged in the anlotinib group than in the placebo group (20.7 months vs. 11.1 months, P = 0.029; HR, 0.53; 95% confidence interval, 0.30–0.95). The ORR of anlotinib treatment was 48.4%. The incidence of treatment-related adverse events (TRAE) was 100% and 89.7% in the anlotinib and placebo groups, respectively. The most common TRAEs of all grades in the anlotinib group were palmar–plantar erythrodysesthesia syndrome (62.9%), proteinuria (61.3%), and hypertriglyceridemia (48.4%). Anlotinib demonstrates its efficacy and safety in this phase IIB trial for the treatment of MTC and may become a new choice for this rare disease, especially for Chinese patients.
