Study Summary

This study will be an open-label, randomized, three-period, six-sequence crossover study of GDC-9545 administered to healthy females of non-childbearing potential to determine the relative bioavailability of the Phase 3 capsule formulation to the Phase 1 tablet formulation in the fasted state and the effect of food on the Phase 3 capsule formulation.

Primary Outcome

The pharmacokinetics (PK) parameters were determined where possible from the plasma concentrations of GDC-9545 using non-compartmental methods performed using Phoenix WinNonlin. The PK parameters Cmax, AUC0-t, and AUC0-∞ for GDC-9545 were analyzed to evaluate the relative bioavailability of GDC-9545 as a Phase 3 capsule formulation compared to a Phase 1 tablet formulation under fasted conditions (Treatment B vs. Treatment A) and to assess the food effect on GDC-9545 PK for a Phase 3 capsule form
