About

This trial is aimed to investigate whether adjuvant PD-1 antibody treatment could improve survival in locoregionally advanced nasopharyngeal carcinoma compared to best supportive care.

Full description

In this multicenter, randomised controlled, phase 3 trial, patients with stage III-IVA (AJCC/UICC 8th system, except T3-4N0 and T3N1) non-metastatic nasopharyngeal carcinoma will be randomized in a 1:1 ratio to recieve PD-1 antibody for 12 doses every 3 weeks or best supportive care after curative chemoradiation.

Enrollment

Inclusion criteria

  • Patients with histologically confirmed nasopharyngeal carcinoma.
  • Tumor staged as III-IVA (AJCC 8th, except T3N0-1 or T4N0).
  • Completed protocol-specified curative chemoradiotherapy, including gemcitabine and cisplatin induction chemotherapy, intensity-modulated radiotherapy, and concurrent cisplatin chemotherapy.
  • Completion of the last radiation dose within 1 to 42 days before randomization
  • Eastern Cooperative Oncology Group performance status ≤1.
  • Adequate marrow function: neutrocyte count≥1.5×10e9/L, hemoglobin ≥90g/L and platelet count ≥100×10e9/L.
  • Alanine Aminotransferase (ALT)/Aspartate Aminotransferase (AST) ≤2.5×upper limit of normal (ULN), and bilirubin ≤ 1.5×ULN.
  • Adequate renal function: creatinine clearance rate ≥ 60 ml/min (Cockcroft-Gault formula).
  • Patients must be informed of the investigational nature of this study and give written informed consent.
  • Women of childbearing potential (WOCBP) who are sexually active must be willing to adhere to effective contraception during treatment and for 1 year after the last dose of study drug. Men who are sexually active with WOCBP must be willing to adhere to effective contraception during treatment and for 1 year after the last dose of the study drug.

Exclusion criteria

  • Age > 65 or < 18.
  • Hepatitis B surface antigen (HBsAg) positive and hepatitis B virus DNA >1×10e3 copies/ml or 200IU/ml
  • Hepatitis C virus (HCV) antibody positive
  • Has active autoimmune disease, except type I diabetes, hypothyroidism treated with replacement therapy, and skin disease that doesn't require systemic treatment (e.g., vitiligo, psoriasis, or alopecia).
  • Has any condition that required systemic corticosteroid (equivalent to prednisone >10mg/d) or other immunosuppressive therapy within 28 days before informed consent. Patients received systemic corticosteroid equivalent to prednisone ≤10mg/d, inhale or topical corticosteroid will be allowed.
  • Has a known history of active TB (bacillus tuberculosis) within 1 year; patients with adequately treated active TB over 1 year ago will be allowed.
  • Has a known history of interstitial lung disease.
  • Has received a live vaccine within 30 days before informed consent or will receive a live vaccine in the near future.
  • Is pregnant or breastfeeding.
  • Prior malignancy within 5 years, except in situ cancer, adequately treated non-melanoma skin cancer, and papillary thyroid carcinoma.
  • Has known allergy to large molecule protein products or any compound of camrelizumab.
  • Has a known history of human immunodeficiency virus (HIV) infection.
  • Any other condition, including symptomatic heart failure, unstable angina, myocardial infarction, active infection requiring systemic therapy, mental illness or domestic/social factors, deemed by the investigator to be likely to interfere with a patient's ability to sign informed consent, cooperate and participate in the study, or interferes with the interpretation of the results.
