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.
Patients with Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 or 1
Evaluable tumor burden assessed by H&N-computed tomography scan (CT-scan) or magnetic resonance imaging (MRI), based on RECIST v 1.1
Patients eligible to cisplatin-based chemotherapy
No hearing loss by clinical assessment or ≤ grade 2 hearing impairment (according to NCICTCAE v.5
Metastatic disease (stage IVC as per AJCC/TNM, 8th Ed.).
Patients having received prior therapy with anti-PD1, anti-PD-L1, anti-PD-L2, anti- CD137, or anti-CTLA-4 antibody (or any other antibody or drug specifically targeting Tcell co-stimulation or checkpoint pathways).
