- MTD and/or RP2D of gamma-secretase/Notch signalling pathway inhibitor RO4929097, determined according to incidence of DLT, graded using the NCI CTCAE [ Time Frame: 6 weeks ]
- Occurrence of adverse events and the associated National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) grade [ Time Frame: Up to 30 days after completion of study treatment ]
- Occurrence of DLTs and the associated NCI CTCAE grade [ Time Frame: 6 weeks ]
- Change in gene expression levels [ Time Frame: Baseline to up to 30 days ]Will be summarized with descriptive statistics appropriate to such distributions.
- Change in percentage of select BCSC biomarkers in the Hh and Notch signaling pathways [ Time Frame: Baseline to 2 weeks of intervention ]Will be summarized with standard descriptive statistics (N, median, mean, standard deviation, minimum, maximum, and the 90% confidence interval for the mean).
- Max concentration (Cmax), time to Cmax (tmax), terminal half-life (t1/2), area under curve 0-infinity (AUC0-inf), AUC 0-next dose (AUCtlast), accumulation index (AI), Cmax steady state (Css, max), and min concentration steady state (Css, min) [ Time Frame: Course 1 days 1-3 or days -2, -1, and 1; course 1 days 17 and 21; and course 2 days 1, 7, 10, and 11 ]Single and multiple-dose PK parameters summarized with standard descriptive statistics (N, median, mean, standard deviation, minimum, maximum, and the 90% confidence interval for the mean).
- Measurement of tumor response using RECIST criteria before and after treatment [ Time Frame: Up to 30 days after completion of study treatment ]Will be described by point estimates and exact 90% confidence intervals for proportions using Wilson's method.
- Pharmacogenetics (PG) parameters, including, but not limited to, metabolizing enzymes (e.g., CYP3A5, 2C9, and UGT1A1) and transporters (e.g., ABCG2 and ABCB1) [ Time Frame: Baseline ]Summarized with standard descriptive statistics (N, median, mean, standard deviation, minimum, maximum, and the 90% confidence interval for the mean).

Experimental: Treatment (RO4929097 and vismodegib)
Patients receive gamma-secretase/Notch signalling pathway inhibitor RO4929097 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 QD beginning day 8 of course 1. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

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 (gamma-secretase/Notch signalling pathway inhibitor 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] proto-oncogene tyrosine-protein kinase [Src] family kinases) 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.
