SIM1910-09

EXPERIMENTAL

This trial includes of 2 parts, Part A-single ascending doses and Part B- multiple ascending doses. Part A, there are 4 dose cohorts and each cohort will enroll 6 subjects to receive SIM1910-09. Part B, there are 4 dose cohorts and each cohort will enroll 6 subjects to receive SIM1910-09. The dose ascending will be determined by independent third party clinical physician. The next higher dose cohort could be initiated only if the stopping rules is not met.

Drug: SIM1910-09

Placebo

PLACEBO COMPARATOR

This trial Includes of 2 parts, Part A-single ascending dose and Part B- multiple ascending dose. Part A, there are 4 dose cohorts and each cohort will enroll 2 subjects to receive placebo. Part B, there are 4 dose cohorts and each cohort will enroll 2 subjects to receive placebo. The dose ascending will be determined by independent third party clinical physician. The next higher dose cohort could be initiated only if the stopping rules is not met.

Drug: Placebo

Interventions
