A Phase 1 Study Assessing the Effect of Food on the Pharmacokinetics of ABBV- CLS-7262

A Phase 1 Study to Evaluate Safety, Tolerability, and Food-Effect Following Administration of ABBV-CLS-7262 in Healthy Volunteers

This study is a randomized, three period, six sequence, single dose crossover design with ABBV-CLS-7262 in healthy adult subjects.

On Day 1 of each period, subjects will receive a single oral dose of ABBV-CLS-7262 administered according to the food regimen assigned. There will be a 4-day washout period between doses. Food regimens include administration after fasting, following a high-fat/high-calorie meal, or with apple sauce. Upon completion each subject will have taken a total of three doses of ABBV-CLS-7262, with one dose administered with each food regimen.
