The purpose of this study is to assess the safety and tolerability of MG1113 in the single ascending dose study (IV injection or SC injection) in healthy subjects and hemophiia patients.
This is a single-dose study that explore the safety, tolerability, PK, and PD of the study drug by sequentially increasing the study drug in 4 dose levels. The route of administration is either subcutaneous (SC) injection or intravenous (IV) injection.

For healthy subjects, 6 subjects will be assigned to the study group and 2 subjects will be assigned to the placebo group to explore the safety and tolerability, and PK/PD of the study drug in comparison with placebo. Hemophilia patients will be assigned only to the study group with 3 and 6 subjects in each cohort, respectively.

The investigator and subjects will know which cohort the healthy subjects have been assigned to, but they will be double-blinded as to whether the subjects are assigned to the study group (study drug) or the placebo group (placebo) within each cohort.

The doses planned in healthy subjects are 0.5 mg/kg, 1.7 mg/kg, and 3.3 mg/kg by SC injection; 3.3 mg/kg by IV injection. In hemophilia patients, 1.7 mg/kg and 3.3 mg/kg will be administered by SC injection. The planned dose will be administered after checking the safety and tolerability at the previous dose to the extent not exceeding the criteria for discontinuation of dose escalation. The dose escalation will be decided by the Data Monitoring Committee(DMC) and Data and Safety Monitoring Boards (DSMB) in the blinded evaluation of the safety and tolerability data obtained from each previous cohort for 7 days after administration. Before deciding dose escalation and proceeding to the next step, the safety, tolerability, PK, and PD data obtained from all healty subjects and hemophilia patients up to cohort 6 will be evaluated by the Data and Safety Monitoring Boards (DSMB) in an unblinded manner. In addition, if necessary, the analysis result of cohort that has completed all the scheduled visits can be reviewed in an unblinded manner.
