Brief Summary
This is an open-label, multicenter, Phase I/II study to assess the safety, tolerability, and pharmacokinetics of GDC-0032. The Phase I portion will be divided into two stages. During Stage 1, GDC-0032 will be administered every day orally and at escalating doses in participants with locally advanced or metastatic solid tumors. During Stage 2, GDC-0032 will be administered alone or as combination therapy within indication-specific cohorts. In Phase II of the study, the efficacy and safety of the combination GDC-0032 and fulvestrant will be evaluated in post-menopausal female participants with locally advanced or metastatic human epidermal growth factor receptor 2 (HER2)-negative, hormone receptor-positive breast cancer.

Phase I, Stage 1: GDC-0032 as Single Agent
EXPERIMENTALParticipants with locally advanced or metastatic solid tumors will receive increasing doses of GDC-0032 administered orally daily in 28-day cycles. Dose escalation decisions will be based upon the observed incidence of DLTs.
Phase I, Stage 2: GDC-0032 + Fulvestrant
EXPERIMENTALParticipants (Cohorts F, J, K, L, and M) will receive GDC-0032 in combination with fulvestrant until disease progression.
Phase I, Stage 2: GDC-0032 + Letrozole
EXPERIMENTALParticipants (Cohorts E, N, P, Q, R, and S) will receive GDC-0032 in combination with letrozole until disease progression.
Phase I, Stage 2: GDC-0032 as Single Agent
EXPERIMENTALParticipants (Cohorts A, B, C, D, G, H, T, T2, and X) will receive GDC-0032 until disease progression.
Phase I, Stage 2: GDC-0032 + Midazolam

Interventions
Participants will receive fulvestrant 500 milligrams (mg) via intramuscular injection (as per package insert or Summary of Product Characteristics \[SmPC\]) on Days 1 and 15 of Cycle 1, then on Day 1 of each subsequent cycle, until disease progression (Cycle length: 28 days).
Participants will receive GDC-0032 at escalating (Phase I, Stage 1) or fixed (Phase II and Phase I, Stage 2) doses until disease progression. Cycle 1 may be 35 days in length to allow for a 7-day washout following the initial dose; thereafter, GDC-0032 will be administered orally once daily in 28-day cycles.
Participants will receive letrozole 2.5 mg orally (as per Package Insert or SmPC) once daily in 28-day cycles until disease progression.
