=================
Brief Summary
-----------------
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.

Detailed Description
-----------------
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.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Safety/Tolerability | Incidence of adverse events and outlier of laboratory tests, positive rate of immunogenicity | 24 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Objective response rate (ORR) | ORR is defined as proportion of patients achieving complete response (CR) or partial response (PR) according to RECIST v1.1 or Lugano 2014 criteria during trial treatment. | 24 months |
