Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a Phase 1, randomized, double-blind, placebo-controlled study consisting of SAD and MAD investigation at a single clinical trial center conducted in healthy adult male subjects assessing the safety, tolerability, PK, and PD of oral FB-101 administration.

Up to 72 healthy adult male subjects will be enrolled. Additional subjects may be enrolled (8 subjects per cohort) if it is deemed appropriate following review (e.g., in the circumstances where a dose level is repeated, or an intermediate dose is conducted or to add another dose level(s) (higher than those planned)).
