DISEASE PROGRESSION, DISEASE
In this prospective, single-arm, phase 2 trial, patients with histologically confirmed RM-NPC and failure of at least two lines of prior systemic treatments were eligible. Anlotinib was given at 12 mg once daily on days 1–14 every 3 weeks until disease progression or intolerable toxicities. The primary end point was disease control rate, defined as the percentage of patients achieving complete response, partial response, or stable disease by RECIST criteria.
