Gemcitabine Combined With Nimotuzumab and Toripalimab as Induction Treatment Followed by Chemoradiotherapy for Locally Advanced Nasopharyngeal carcinoma-a Multicenter, Randomized Controlled Study
The goal of this clinical trial is to compare overall response rate between gemcitabine, nimotuzumab and toripalimab as induction treatment and gemcitabine combined with cisplatine in paitents with locally advanced nasopharyngeal carcinoma. It aims to answer whether gemcitabine, nimotuzumab and toripalimab as induction treatment show non-inferiority compared to GP induction chemotherapy. Participants will be randomly divided into two induction treatment groups.
• Age 18 to 75 years old.
• Pathologically or cytologically confirmed stage III-IVB nasopharyngeal keratinizing squamous cell carcinoma or non-keratinizing squamous cell carcinoma.
• Patients suitable for radical radiochemotherapy.
• ECOG PS score of 0-1.
• According to the RECIST 1.1 criteria, there is at least one measurable lesion. Basic hematological parameters are normal: white blood cell count ≥4×10\^9/L; absolute neutrophil count ≥1.5×10\^9/L; platelets ≥100×10\^9/L; hemoglobin ≥90 g/L.
• Basically normal renal function: serum creatinine ≤1.5×ULN or creatinine clearance rate (CrCl) \> 60 mL/min (using the Cockcroft-Gault formula): For females: CrCl = (140-age) x weight (kg) x 0.85 / (72 x Scr mg/dl) For males: CrCl = (140-age) x weight (kg) x 1.00 / (72 x Scr mg/dl)
• Basically normal liver function: serum total bilirubin ≤1.5×ULN; aspartate aminotransferase (AST) ≤2.5×ULN; alanine aminotransferase (ALT) ≤2.5×ULN.
• Signed written informed consent.
