About this trial
To explore and evaluate the dose-limiting toxicity (DLT) profile of the fixed-dose combination of toripalimab, anlotinib, and chidamide in patients with recurrent/metastatic nasopharyngeal carcinoma (R/M NPC), and to determine the maximum tolerated dose (MTD) of chidamide, thereby informing subsequent clinical dosing regimens.
To assess the objective response rate (ORR) of the combination regimen in this patient population.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
None
Disqualifiers
Known severe hypersensitivity (≥Grade 3) to any monoclonal/polyclonal antibody, chidamide, or anlotinib components.
Necrotic lesions identified within 4 weeks prior to enrollment, with investigator-judged risk of major bleeding.
Chemotherapy, targeted therapy, or immunomodulatory agents (including thymosin, interferon, IL-2, etc.) within 2 weeks prior to enrollment.
Palliative radiotherapy to localized lesions within 4 weeks prior to enrollment, unless the lesion is non-target and other measurable target lesions exist.
