A Study of Relative Bioavailability and Food Effect Study of Cobimetinib in Healthy Participants

A Phase I, Single-Dose, Randomized, Cross-Over, Relative Bioavailability, and Food Effect Study of GDC-0973 in Healthy Subjects

This study will be an open-label, randomized, 3-way, 6-sequence crossover study in healthy participants 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.
