Study of CD137 Agonist ADG106 With Advanced or Metastatic Solid Tumors and/or Non-Hodgkin Lymphoma

Study Overview
=================
Brief Summary
-----------------
This is a Phase 1, open-label, dose-escalation, multicenter study of ADG106 in subjects with advanced or metastatic solid tumors and/or relapsed/refractory non-Hodgkin lymphoma. ADG106 is a fully human ligand-blocking, agonistic anti-CD137 IgG4 mAb. It binds to the activated human T cells via a T cell receptor CD137. T cell is a kind of lymphocyte (a subtype of white blood cells) that protects bodies by eliminating tumor cells, and normal cells infected with viruses or bacteria. By binding to CD137, the study drug is expected to enhance the activity of activated T cells and thus stimulate a more intense immune attack to kill tumor cells. ADG106 is expected to enhance the activity of activated T cells. The primary objective of the study is to assess safety and tolerability at increasing dose levels of single agent ADG106 in subjects with advanced or metastatic solid tumors and/or non Hodgkin lymphoma Secondary Objectives To characterize the pharmacokinetic (PK) profiles of ADG106 To evaluate the immunogenicity of ADG106 To evaluate the potential anti-tumor effect of ADG106 Exploratory Objective To identify the potential biomarkers of ADG106
