Brief Summary

This is a randomized, double-blind, first-in-human study to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of single and multiple oral doses of YH35995

Detailed Description

YH35995 is being developed as a treatment for the neurological symptoms of Gaucher Disease type 3. This study is a first-in-human (FIH), phase 1, randomized, double-blind, placebo-controlled study of YH35995, which consists of two parts. In Part A (SAD), single ascending dose of YH35995 is administered to healthy male participants to assess its safety, tolerability, PK, and PD. In Part B (MAD), multiple ascending dose of YH35995 is administered to healthy male participants to assess its safety, tolerability, PK, and PD.

YH35995YH35995\[Part A\] Participants will be orally administered a single dose of YH35995 in six dose groups, gradually escalating from lower to higher doses. Each cohort includes 10 participants (8 randomly assigned to the YH35995 arm and 2 randomly assigned to the placebo arm). \[Part B\] Participants will receive multiple oral doses of YH35995 once every 4 weeks in three dose groups. Each cohort includes 12 participants (9 randomly assigned to the YH35995 arm and 3 randomly assigned to the placebo arm).
PlaceboPlacebo\[Part A\] Participants will be orally administered a single dose of Placebo in six dose groups, gradually escalating from lower to higher doses. Each cohort includes 10 participants (8 randomly assigned to the YH35995 arm and 2 randomly assigned to the placebo arm). \[Part B\] Participants will receive multiple oral doses of Placebo once every 4 weeks in three dose groups. Each cohort includes 12 participants (9 randomly assigned to the YH35995 arm and 3 randomly assigned to the placebo arm).
