A Study to Evaluate the Tolerance and Pharmacokinetics of TQB2618 Injection in Subjects With Advanced Solid Tumors

A Phase I, Open-label, Dose Escalation and Expansion Study to Evaluate the Tolerance and Pharmacokinetics of TQB2618 Injection in Subjects With Advanced Solid Tumors

TQB2618 is a TIM-3 receptor monoclonal antibody that binds to the extracellular domain of TIM-3 outside the cell to block the binding of TIM-3 to its ligand, thereby inhibiting the downstream signal transduction of TIM-3 and deactivating TIM-3 Inhibition of immune cells. The purpose of this study was to evaluate the safety, tolerability, pharmacokinetic parameters and antitumor effects of TQB2618 injection in subjects with advanced solid tumors.
