Healthy Volunteer
Conditions
Brief summary
This 4-part study will assess the effect of formulation, food, and active pharmaceutical ingredient (API) lot on the pharmacokinetics of GDC-0032 in healthy volunteers. Part 1 is an open-label, 3-period, 6-sequence study, and Parts 2, 3, and 4 are open-label 2-period crossover studies. Participants will receive single doses of GDC-0032 capsule or tablet formulation, in the fasted or fed state.
Interventions
Participants will receive 2 mg or 3 mg Phase III tablet after 10 hour fasting from food.
Participants will receive 3 mg Tablet A or Tablet B formulation after 10 hour fasting from food.
Participants will receive 3 mg GDC-0032 capsule formulation after 10 hour fasting from food.
