Single Ascending Dose and Multiple Ascending Dose Study of AVR-48

This is a Phase 1 (healthy adult volunteers), 2-part, double-blind, randomized, placebo controlled trial to evaluate the safety and pharmacokinetic (PK) profiles of escalating single doses of AVR-48 versus placebo (SAD) and escalating multiple doses of AVR-48 versus placebo (MAD). SAD will be initiated first and include a sentinel dosing design. MAD will not utilize a sentinel design unless the safety monitoring committee requests the addition of sentinels. The MAD will be initiated once the lowest doses from SAD are deemed safe.
