A Clinical Study to Evaluate the Efficacy and Safety of LIV-GAMMA SN Inj.10% in Primary Immune Thrombocytopenia (ITP)

The purpose of this study is to evaluate the efficacy and safety of LIV-GAMMA SN Inj.10% administered for 2 days in adult subjects with primary immune thrombocytopenia (ITP). The primary objective of this study is to determine the responder rate. A response is defined as a platelet count of ≥30×10\^9/L and at least a 2-fold increase of the baseline, confirmed on at least 2 separate occasions at least 7 days apart without bleeding. The secondary objectives are to evaluate the further efficacy assessments including time to response and duration of response, and the safety of LIV-GAMMA SN Inj.10%.
