Clinical trials

This is a multicenter, randomized, open-label, controlled Phase 2 trial evaluating neoadjuvant MRG003 (anti-EGFR ADC) plus toripalimab versus toripalimab alone in PD-L1-positive (CPS ≥ 1), resectable, locally advanced head and neck squamous cell carcinoma (LA-HNSCC). Patients are randomized 2:1 to receive 2 cycles of MRG003 2.0 mg/kg IV plus toripalimab 240 mg IV Q3W (n=43) or toripalimab 240 mg IV Q3W alone (n=22), followed by surgery and risk-adapted adjuvant therapy including radiotherapy and toripalimab maintenance. The primary endpoint is Major Pathological Response (MPR) rate. Secondary endpoints include pCR, ORR, EFS, R0 resection rate, surgical down-staging, and safety. Enrolling 65 participants across 11 centers in China.

This study aims to explore a superior first-line induction remission regimen by incorporating Chidamide into the modified VAH chemotherapy combined with targeted therapy regimen, leveraging its dual epigenetic modulation mechanism.
