This phase I trial studies the side effects and best dose of RO4929097 (gamma-secretase/Notch signalling pathway inhibitor RO4929097) when given together with vismodegib in treating patients with breast cancer that is metastatic or cannot be removed by surgery. RO4929097 and vismodegib may slow the growth of tumor cells and may be an effective treatment for advanced breast cancer.
Further Study Information
I. To determine the safety and tolerability of continuous daily administration of 150 mg/day of GDC0449 (vismodegib) in combination with escalating doses of RO4929097 administered on a repeated schedule of days 1-3, 8-10 every 21 days (for a total of 6 days of RO4929097 administration per 21 day cycle) in patients with advanced breast cancer.
II. To determine the dose limiting toxicity (DLT) and identify the maximum tolerated dose (MTD) and/or recommended phase 2 dose (RP2D) for this administration schedule.
I. To determine the pharmacokinetics (PK) and pharmacogenetics (PG) of GDC0449 and RO4929097, each alone and in combination.
II. To attempt to evaluate select pharmacodynamic (PD) stem cell differentiation biomarkers in the hedgehog and notch signaling pathways (e.g. GLI family zinc finger [Gli]1/2/3, patched [Ptch] 1/2, hairy and enhancer of split 1, [Drosophila] [Hes1], huntingtin interacting protein 1 [Hip1], hairy/enhancer-of-split related with YRPW motif 1 [Hey1], Notch4, Jagged1, numb homolog [Drosophila] [numb], BMI1 polycomb ring finger oncogene [Bmi-1], cluster of differentiation [CD]44/CD24, aldehyde dehydrogenase [ALDH]) and the percentage of breast cancer stem cell (BCSC) in serial breast tumor biopsies before and after GDC0449 or RO4929097 alone and after 1 cycle of treatment with the combination of GDC0449 and RO4929097.
III. To determine tumor response in patients with measurable disease as assessed by the Response Evaluation Criteria in Solid Tumors (RECIST).
IV. To perform molecular profiling of the tumor cell and BCSC populations before and after GDC0449 or RO4929097 alone and after 1 cycle of treatment with the combination of GDC0449 and RO4929097 at the MTD.
OUTLINE: This is a dose-escalation study of gamma-secretase/Notch signalling pathway inhibitor RO4929097.
Patients receive gamma-secretase/Notch signalling pathway inhibitor RO4929097 orally (PO) on day 1 or days -2, -1, and 1 of course 1 and days 1-3 and 8-10 of course 2 and all subsequent courses. Patients also receive vismodegib PO once daily (QD) beginning day 8 of course 1. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up for 30 days.

- Patients with known active brain metastases will be excluded from this clinical trial; patients with prior treated brain metastases (treated and stable for >= 1 month) are allowed, providing that they were not accompanied by seizures and that a baseline brain magnetic resonance imaging (MRI) scan prior to study entry demonstrates no current evidence of progressive brain metastases
- Any patient requiring chronic maintenance of white blood cell counts or granulocyte counts through the use of growth factor support (e.g. Neulasta, Neupogen)
- HIV-positive patients on combination antiretroviral therapy are ineligible
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements

- GDC is a cytochrome P450 2C9 (CYP2C9) inhibitor; CYP2C9 is an enzyme that metabolizes warfarin sodium (Coumadin) into an inactive metabolite; patients who are on warfarin anticoagulation are allowed to participate as long as they fit the following 4 criteria:
- They are therapeutic on a stable warfarin dose
- Their international normalized ratio (INR) target range is no greater than 3
- They are monitored with weekly INR testing
