Comparing toripalimab with placebo in treating advanced nasopharyngeal carcinoma

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial evaluates the efficacy and safety of toripalimab, an anti-PD-1 therapy, when combined with gemcitabine and cisplatin (GP) induction chemotherapy in patients with locoregionally advanced nasopharyngeal carcinoma. Participants will be randomly assigned to receive either the toripalimab combination or a placebo alongside GP chemotherapy. The study aims to determine if the addition of toripalimab improves progression-free survival, overall survival, and response rates compared to the placebo group. Additionally, it will assess safety profiles and explore potential predictive biomarkers related to treatment outcomes.

9. 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 the 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:

1. Age \> 70 years or \< 18 years.
2. Patients with recurrence or distant metastases.
3. Pathologically confirmed nasopharyngeal keratinizing squamous cell carcinoma (WHO Type I).

6. Hepatitis C virus (HCV) antibody positive.
7. 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).
8. Has any condition that required systemic corticosteroid (equivalent to prednisone \>10mg/d) or other immunosuppressive therapy within 28 days before informed consent. Patients who received systemic corticosteroid equivalent to prednisone ≤10mg/d, inhale or topical corticosteroids will be allowed.
9. Has a known history of active bacillus tuberculosis within 1 year; patients with adequately treated active bacillus tuberculosis over 1 year ago will be allowed.
10. Has a known history of interstitial lung disease.
