Safety, Tolerability, Pharmacokinetics and Efficacy of SCT-I10A in Patients With Advanced Solid Tumors or Lymphoma

Recombinant Humanized Anti- PD-1 Monoclonal Antibody（SCT-I10A） in Patients With Advanced Solid Tumors or Lymphoma :a Phase Ⅰ, Open-label, Multicenter Study

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics and preliminary efficacy of recombinant humanized anti- PD-1 monoclonal antibody（SCT-I10A）in patients with advanced solid tumors or lymphoma treated after failure of standard therapy.

This open label, multicenter phase I study is designed to evaluate the safety, tolerability, pharmacokinetics and preliminary efficacy in advanced solid tumors or lymphoma treated with anti- PD-1 monoclonal antibody SCT-I10A. The trial will be divided into two parts: dose-exploration and indication expansion.
