A Study to Compare the PK , Safety, Tolerability, and Immunogenicity of HLX13 With YERVOY in Male Subjects

Study Overview
=================
Brief Summary
-----------------
Phase I Study to Compare the Pharmacokinetic Characteristics, Safety, Tolerability, and Immunogenicity (Randomized, Double-blind, Parallel Controlled) of HLX13 with YERVOY® Injection in Healthy Chinese Male Subjects

Detailed Description
-----------------
This is a randomized, intravenous single-dose, parallel study to compare the PK characteristics of HLX13 and YERVOY® (US-, EU-, and CN-sourced) and evaluate their safety, tolerability, and immunogenicity in healthy Chinese male subjects. This study is divided into two parts. Part I is an open-label, randomized, single-dose, parallel study to compare the PK parameters of HLX13 with those of EU-sourced YERVOY® in healthy Chinese male subjects after a single intravenous infusion and provide supporting data for the design of Part II. This part of the study consists of two groups. Part II is a double-blind, randomized, single-dose, parallel study to evaluate the PK similarity of HLX 13 and YERVOY® (US-, EU-, and CN-sourced) in healthy Chinese male subjects. This part of the study consists of four groups.
