1. Part 1 Randimization, Double blinded, Placebo controlled, Dose escalation(10mg, 20mg, 40mg) of MIT-001 SC or IV single administration to evaluate safety, tolerability and PK in healthy adult.
2. Part2 Randimization, Double blinded, Placebo controlled, MIT-001 SC multiple administration for 7days (20mg & 40mg) to evaluate safety, tolerability and PK in healthy adult.

This is a Phase 1, randomized, double-blind, placebo-controlled, single and multiple dose, dose escalation clinical trial in 40 healthy subjects.

Subjects will be assigned in 6:2 allocation to receive active or placebo treatments.
