A Phase 1 Study of GC1102 (Recombinant Hepatitis B Immunoglobulin) in Chronic Hepatitis B Patients

This study is SAD(Single Ascending Dose)/MAD(Multiple Ascending Dose) study to Explore the Tolerability, Safety and Pharmacokinetics/Pharmacodynamics of GC1102 (Recombinant Hepatitis B Human Immunoglobulin) in Chronic Hepatitis B Patients.

GC1102 is a new recombinant hepatitis B human immunoglobulin. This study is composed with 2 Parts, Part A for SAD and Part B for MAD and total 4 dosing program which is escalated after confirming safety. Maximum 48 subjects will be participated in the study.
