About

This study is a randomized, double-blind, placebo-controlled first-in-human study in which the safety, tolerability, pharmacokinetics and pharmacodynamics of orally administered HPN-01 will be evaluated in healthy subjects

Full description

This study aims to obtain safety, tolerability, pharmacokinetic and pharmacodynamic data when HPN-01 is orally administered as single doses and as multiple doses to healthy subjects.

The study will be conducted in 2 parts: a single ascending dose (SAD) phase (Part 1) and a multiple ascending dose (MAD) phase (Part 2). One cohort of Part 1 will receive HPN-01 after a standard high fat/high calorie breakfast (the fed condition) to investigate the effect of food on the pharmacokinetics of HPN-01.

Enrollment: 72 estimated patients

Sex: All

Ages: 18 to 55 years old

Volunteers: Accepts Healthy Volunteers
