A Phase Ia Clinical Study to Evaluate the Safety, Tolerability, PK and Immunogenicity of YBSW015 in Healthy Subjects
Study Details
Study Description
Brief Summary
This is phase Ia study to research YBSW015 injection which is a monomolecular bispecific antibody. The Primary objective is to evaluate the safety and tolerability of YBSW015 injection after a single intravenous injection at different doses in healthy subjects.
The Secondary objective is to evaluate the pharmacokinetic characteristics and immunogenicity of different doses of YBSW015 injection after a single intravenous injection in healthy subjects. This study is a single-center, randomized, double-blind, placebo-controlled, single-dose escalation clinical trial.
