简要总结
To evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of single intravenous doses of KL0011034 injection in healthy volunteers.
详细描述
This trial is a randomized, double-blind, placebo- and active-controlled, single-dose escalation study in healthy volunteers. A total of 76 volunteers will be enrolled. Healthy volunteers will be randomly assigned to receive KL0011034 injection, placebo, or Etomidate Injectable Emulsion. Each volunteer is allowed to participate in only one dose cohort; intra-volunteer dose escalation is not permitted. Enrollment into the next cohort will begin only after safety and tolerability data from the previous cohort have been reviewed and deemed acceptable by the investigator(s) and sponsor. If the highest dose is well tolerated, the investigator(s) and sponsor will evaluate the accumulated data and decide whether to terminate dose escalation or continue to higher dose levels.
