研究组 & 干预措施
ASP5094 Dose Escalation
Three sequential cohorts will receive increasing intravenous doses of ASP5094. After all subjects in a cohort have completed study procedures the overall safety and tolerability of the dose will be determined after evaluation of the safety data. If there are no events which meet the stopping criteria, the next sequential cohort will begin enrollment while the current subjects continue through the third dose and the remainder of the study.
干预措施: ASP5094 (Drug)
Placebo Dose Escalation
Three sequential cohorts will receive increasing intravenous doses of Placebo. After all subjects in a cohort have completed study procedures the overall safety and tolerability of the dose will be determined after evaluation of the safety data. If there are no events which meet the stopping criteria, the next sequential cohort will begin enrollment while the current subjects continue through the third dose and the remainder of the study.
