A Clinical Trial of TQB2618 Injection Combined With Penpulimab Injection and Chemotherapy Versus Penpulimab Injection Combined With Chemotherapy in First-line Treatment of Relapsed/Metastatic Head and Neck Squamous Cell Carcinoma

"TQB2618 injection is an Anti TIM-3 (T-cell immunoglobulin and mucin domain-3) monoclonal antibody.~Penpulimab injection is a humanized Monoclonal Antibody target Programmed Cell Death Protein 1 (PD-1).~Paclitaxel is a anti-microtubule drug, which promotes tubulin polymerization, inhibits depolymerization, maintains tubulin stability and inhibits cell mitosis.~Cisplatin inhibits DNA synthesis by generating in-strand interstrand crosslinking with DNA. Protein and RNA synthesis can also be inhibited.~Carboplatin is a cyclic nonspecific antitumor agents that cause cross-linking between DNA strands and affect their synthesis to inhibit cancer cells."
