A Study of Relative Bioavailability and Food Effect Study of GDC-0973 in Healthy Subjects

• PK parameters of GDC-0973 (including total exposure, maximum and minimum serum concentration, clearance, volume of distribution) [ Time Frame: Following administration of study drug ] [ Designated as safety issue: No ]
• Incidence, nature, and severity of adverse events and serious adverse events [ Time Frame: Through study completion or early study discontinuation ] [ Designated as safety issue: No ]

This study will be an open-label, randomized, 3-way, 6-sequence crossover study in healthy subjects for determining the relative bioavailability of the tablet formulation to the capsule formulation and the effect of food on the relative bioavailability of the tablet formulation.
