Brief summary: This study is a single-center, open-label, 2-cohort, fixed-sequence, DDI study in healthy adult subjects. Healthy volunteers will be administered multiple oral doses of ATI-2173 in combination with midazolam or clarithromycin and assessed for safety and tolerability including blood tests to show how the body metabolizes and eliminates the investigational drug as well as how the investigational drug interacts with midazolam or clarithromycin.
