Five hundred patients with recurrent metastatic nasopharyngeal carcinoma will be randomly assigned to the experimental group or the control group. The experimental group will receive mitoxantrone hydrochloride liposome injection combined with capecitabine, and the control group will receive capecitabine alone. All patients will be treated until disease progression as determined by the investigator based on RECIST 1.1 criteria, intolerable toxicity, subject withdrawal of informed consent, initiation of new antitumor therapy, loss of follow-up, death, or study completion, whichever occurs first. Regular visits and imaging examinations will be conducted to compare the efficacy and safety of the two groups.
This is a randomized, open-label, positive-controlled, multicenter Phase Ш study to evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection combined with capecitabine versus capecitabine monotherapy in patients with recurrent metastatic nasopharyngeal carcinoma.
