Clinical Trial Summary

This study will test the safety and effects of SBT115301 when given as a single dose to healthy adult volunteers. It is the first study being done in humans. Increasing dose levels will be given after the safety at lower dose levels is shown. Some participants will receive placebo, and neither the participants or the study staff will know what drug (SBT115301 or placebo) is being given.
