Brief summary

This is a randomized, double-blind, placebo-controlled, single ascending oral dose and food effect study conducted at one study center in the United States. Safety and tolerability will be assessed throughout the study and serial blood samples and urine samples will be collected for the safety and pharmacokinetic assessment of SXC-2023.
