Study Overview
Brief Summary
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.

Inclusion Criteria
- •Age: ≥18 years and ≤70 years, gender unrestricted.
- •Diagnosis: Histologically/pathologically confirmed metastatic nasopharyngeal carcinoma (NPC) that has failed at least one prior line of therapy (including cisplatin-containing regimens) or is intolerant to existing therapies (relapse within 6 months after completion of adjuvant/neoadjuvant concurrent chemoradiotherapy is eligible).
- •3. Performance Status: ECOG performance status 0-
- •Measurable Disease: At least one measurable lesion per RECIST 1.1 criteria.
- •Prior Immunotherapy:
- •Patients who have received PD-1, PD-L1, PD-L2, or CTLA-4 inhibitors, or other therapies targeting T-cell co-stimulation/checkpoint pathways:
- •Must have achieved complete response (CR), partial response (PR), or stable disease (SD) ≥6 months during treatment.
- •Only one prior immunotherapy regimen is allowed (e.g., neoadjuvant and adjuvant regimens using the same immunotherapy are considered one regimen).
- •Switching to a different immunotherapy regimen for non-immunotherapy-related progression is permissible if cumulative SD duration ≥6 months.
- •6. Organ Function:
- •Hematology:
- •ANC ≥1.5×10⁹/L, PLT ≥75×10⁹/L, Hb ≥90 g/L. No blood product transfusion or growth factor support (e.g., G-CSF, EPO) within 2 weeks prior to screening.
- •Hepatology:
- •TBIL ≤1.5×ULN; ALT/AST ≤2.5×ULN (≤5×ULN if liver metastases present).
- •Renal Function:
- •Serum Cr ≤1.5×ULN or CrCl >60 mL/min.
- •Thyroid Function:
- •TSH, FT4, FT3 within CTC AE Grade 0-
- •Survival Expectancy: ≥3 months.
- •Informed Consent: Voluntary participation and signed written informed consent.
Exclusion Criteria
- •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.
- •Washout period determined by clinical resolution of adverse events (AEs) and prior treatment regimens.
- •Palliative radiotherapy to localized lesions within 4 weeks prior to enrollment, unless the lesion is non-target and other measurable target lesions exist.
- •Grade ≥3 irAEs during prior immunotherapy.
- •Prior treatment with HDAC inhibitors or anti-angiogenic agents.
- •Urine protein ≥2+ or 24-hour urinary protein ≥1 g.
- •Systolic BP >140 mmHg or diastolic BP >90 mmHg despite treatment.
- •Persistent toxicity from prior antitumor therapy (per NCI CTCAE v5.0) >Grade 1, excluding: alopecia, Grade 2 fatigue, Grade 2 anemia, or asymptomatic lab abnormalities.
- •Symptomatic CNS metastases (e.g., edema, steroid requirement) or leptomeningeal disease.
- •Systemic immunosuppressive drugs (excluding topical/inhaled corticosteroids or physiological doses ≤10 mg/day prednisone equivalent) or corticosteroids for contrast allergy within 4 weeks prior to enrollment.
- •Active autoimmune diseases (e.g., interstitial pneumonia, colitis, thyroiditis) or history of severe autoimmune conditions requiring systemic therapy.
- •Exceptions: Vitiligo, childhood asthma (resolved without treatment), or mild asthma managed without bronchodilators.
- •Ongoing anti-tuberculosis therapy or treatment within 1 year prior to screening.
- •Conditions requiring long-term immunosuppressive therapy or systemic corticosteroids at immunosuppressive doses.
- •Severe Cardiac Disease or Significant Cardiac Symptoms.
- •Other Circumstances Deemed Unsuitable by the Investigator
