A Study to Test the Effects of Nezavist at Different Doses in Healthy Adults

Eligible participants will undergo intake procedures and baseline evaluations at the clinic the day before dosing. The next day, participants will be randomized to, and receive, either Nezavist SDD oral suspension or placebo vehicle (4 cohorts of escalating doses of Nezavist with 6 Nezavist subjects and 2 placebo subjects in each cohort). Participants will remain in the clinic for at least an additional 48-hours for safety assessments and blood collections to determine plasma levels of Nezavist, then will be discharged from the clinic and return for follow-up safety tests 72-hours later.
