Brief Summary
The purpose of this study is to Assess Dose-Response, Efficacy (Immunogenicity) and the Safety of GC1109 Administered in Multi Intramuscular Doses to Healthy Subjects.
Detailed Description
Step 1 Primary objective Investigate the optimum volume of GC1109 to compare the subject ratio after seroconversion in each Anti-PA Ab by TNA at 4 weeks following infuse the drug 3 times with the immunogenicity of each treatment (GC1109 and placebo cohort) in healthy adults. In healthy adults, three times the clinical dose of about four weeks, compare immunogenicity of each treatment group (GC1109 group and the placebo group) with subsects ratio who have been Seroconversion for Anti-PA Ab by TNA Secondary objective Percentage of subjects after seroconversion in each anti-PA IgG level (by ELISA) at 4 weeks following infuse the drug 3 times in healthy adults Check the Seroprotection antibody titer (survival rate : 50%) with passive immune (nonclinical tests) at 4 weeks following infuse the drug 3 times in healthy adults Establish the Seroconversion rate from the percentage of subjects after seroconversion at 4 weeks following infuse the drug 3 times and seroprotection antibody titer in healthy adults Compare the immunogenicity of each treatment with the GMT's assessment of Anti-PA Ab by TNA for 4 weeks following infuse the drug 3 times Compare the immunogenicity of each treatment with the GMT's assessment of Anti-PA IgG by ELISA for 4 weeks following infuse the drug 3 times Determine the safety of the each treatment cohort Step 2 Primary objective • Evaluate whether the Toxin Neutralization Antibody by TNA assay satisfy the NF50 standard or not at 4 weeks following infuse the optimal dose of GC1109 4 times in healthy adults. Secondary objective Establish the safety of the GC1109 in healthy adults Establish the GMT of Toxin Neutralization Antibody by TNA assay after infusing the drug 4 times until 24 weeks in healthy adults Establish the GMT of Anti-PA IgG by ELISA after infusing the drug 4 times until 24 weeks in healthy adults
