INDV-2000 First in Human

This study is a single ascending dose (SAD) study conducted to identify the maximum tolerated dose (MTD) of INDV-2000. After completion of the SAD portion of the study and acceptable safety evaluation, a food-interaction, single-dose study under fed and fasted conditions will be conducted.
