Brief summary
* Study Design * Randomized, Double-blind, Placebo-controlled, escalating single-dose design. * Five ascending dose cohorts. * In each cohort, subjects will be randomized to receive a single dose of HM10460A or placebo (negative control) * Objectives * The primary objective of the study is to assess the safety and tolerability of single escalating subcutaneous doses of HM10460A in healthy adult Korean Subjects
Detailed description
The secondary objectives of the study are as follows: * to assess the pharmacokinetics (PK) of a single subcutaneous dose of HM10460A. * to assess the relationship between the serum concentration of HM10460A and absolute neutrophil count (ANC). * to assess the relationship between the serum concentration of HM10460A and CD34+ cell counts in the blood. * to assess the immunogenicity (HM10460A, native G-CSF antibody,neutralizing antibodies) of a single subcutaneous dose of HM10460A.
