Phase 1
Completed
Conditions
Healthy Volunteer
Interventions
Drug: GDC-0032 Phase III Tablet
Drug: GDC-0032 Tablet
Drug: GDC-0032 Capsule
Registration Number
NCT01980953
Lead Sponsor
Genentech, Inc.
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.

Part 1: Food EffectGDC-0032 Phase III TabletGDC-0032 will be administered orally over 3-Treatment Period (TP) in 6-sequence as one 3 milligrams (mg) capsule in TP-A after 10 hour fasting from food, one 3 mg Phase III tablet in TP-B after 10 hour fasting from food and one 3 mg Phase III tablet in TP-C following the start of standard Food and Drug Administration (FDA) high-fat breakfast. Washout period o 14 to 20 days will be given between each TP.
Part 2: Tablet Formulation ComparisonGDC-0032 TabletDifferent formulations of tablets (Tablet A and Tablet B) of GDC-0032 will be administered orally over 2-TP having 10 hour fasting from food. Participants will receive one 3 mg Tablet A in TP-A and one 3 mg Tablet B in TP-B after 14 to 20 days washout period.
Part 4: Tablet Relative BioavailibityGDC-0032 Phase III TabletGDC-0032 will be administered orally in crossover fashion over 2-TP to 20 participants having 10 hour fasting from food. Participants will receive one 3 mg capsule in TP-A and one 2 mg Phase III tablet in TP-B after 14 to 20 days washout period.
