A 3-Part Study to Determine the Relative Bioavailability of Capsule and Tablet Formulations of GDC-0980, the Effect of Food, and the Effect of Rabeprazole on the Pharmacokinetics of the Tablet

This will be a single-center, open-label, 3 part study. The study is designed to determine the relative bioavailability of GDC-0980 capsule and tablet formulations under fasting conditions, the effects of a high-fat (fed) meal on the pharmacokinetics of the GDC-0980 tablet, and the effects of rabeprazole on the pharmacokinetics of the GDC-0980 tablet in the presence or absence of a high-fat meal.
