Summary
Brief summary (as posted)
The primary objective of this study is to compare the objective response rate (ORR) of patients with LA-HNSCC, treated with induction of EGFR-ADC MRG003 and anti PD-1 Pucotenlimab versus EGFR-ADC MRG003 alone before chemoradiotherapy. People eligible to participate in this study must be between the ages of 18 and 75 and have locally advanced squamous cell carcinoma of the head and neck requiring treatment with chemoradiotherapy (cisplatin combined with radiotherapy). Half of the research participants will receive MRG003 alone as induction before radiochemotherapy and the other half will receive MRG003 combined with pucotenlimab as induction before radiochemotherapy, then pucotenlimab as adjuvant\* after radiochemotherapy.
