简要总结

The purpose of this clinical trial is to evaluate the safety and tolerability of TNM005 following a single dose by intramuscular (IM) administration in healthy adult subjects The main questions it aims to answer are:1. safety profile；2. PK properties 3. PD properties

详细描述

This is a randomized, double-blind, placebo-controlled, single ascending dose, phase 1 study designed to evaluate the safety, tolerability, PK, PD (anti-VZV antibody level), and immunogenicity of TNM005, as well as to characterize the PD of VARIZIG, in healthy adult volunteers.

The study also includes a cohort in which eight subjects will receive a single dose of VARIZIG 625 IU. This cohort will be conducted in an open-label fashion and may be initiated as early as the first TNM005 cohort is dosed.

The study include periods of Screening (up to 28 days), in-patient (treatment on Day 1), and safety follow-up until Day 120.
