The Phase I Study of Recombinant Human Nerve Growth Factor Injection

Study Overview
=================
Brief Summary
-----------------
A randomized, double-blind, placebo-controlled, single/multiple dose study of recombinant human nerve growth factor injection in healthy Chinese volunteers on safety, tolerability and pharmacokinetics

Detailed Description
-----------------
This is a randomized, double-blind, placebo-controlled, single / multiple dose trial. recombinant human nerve growth factor injection in healthy Chinese volunteers on safety, and pharmacokinetics.The volunteers will be given the drug by intramuscular injection. The main purpose of this trial is to investigate the safety, tolerability , pharmacokinetics and immunogenicity of Chinese healthy volunteers after intramuscular injection of recombinant human nerve growth factor injection, to provide a safe dose range for subsequent clinical trials, as well as a safe and reasonable drug delivery program.
