Study Groups

Part 1: GDC-0334

Participants in up to 7 cohorts will receive single, ascending doses of GDC-0334 under fasting conditions.

Group Type: EXPERIMENTAL

GDC-0334

Intervention Type: DRUG

Part 1: GDC-0334 given orally with dose escalation between cohorts, based on emerging safety and pharmacokinetic (PK) data. Parts 2 and 3: doses to be based on the safety, tolerability, and PK data generated in the study. The dosing duration in Part 3 is planned to be at least 14 days, but no longer than 28 days.

Part 1: Placebo

Participants in up to 7 cohorts will receive single doses of placebo under fasting conditions.
