Brief Summary
-----------------
The purpose of this study is to assess the safety, tolerability, and pharmacokinetics of different dose levels of PRV-002 in Health Volunteers

Detailed Description
-----------------
This Phase 1 study is designed to assess the safety, tolerabilty and pharmcokinetics of different dose levels of PRV-002 in Healthy Volunteers. The study will evaluate 3 dose levels of the investigational product, PRV-002, in 3 cohorts of 8 healthy volunteers per cohort. In each cohort, 6 volunteers will receive the investigational product and 2 volunteers will receive placebo. Dose levels will be evaluated in a sequential manner starting at the lowest dose level.
