Purpose
This phase II trial is studying how well GDC-0449 works in treating patients with advanced chondrosarcomas. Drugs used in chemotherapy, such as GDC-0449, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing

- 6-month clinical benefit (CR + PR + SD) rate [ Time Frame: 6 months ] [ Designated as safety issue: No ]
- Progression-free survival [ Time Frame: Up to 3 months ] [ Designated as safety issue: No ]Will be analyzed using the Kaplan-Meier method. The median survival rates will be reported with a 95% confidence interval. Median follow-up will be calculated using the reverse Kaplan-Meier method.
- Overall survival [ Time Frame: Up to 3 months ] [ Designated as safety issue: No ]Will be analyzed using the Kaplan-Meier method. The median survival rates will be reported with a 95% confidence interval. Median follow-up will be calculated using the reverse Kaplan-Meier method.
- Duration of response [ Time Frame: Up to 3 months ] [ Designated as safety issue: No ]Will be described in responding subjects using descriptive statistics (median, extreme values, etc.).

Detailed Description:
PRIMARY OBJECTIVES:
I. Evaluate the antitumor activity of GDC-0449 in terms of 6-month clinical benefit rate (complete response, partial response, and stable disease, as per the revised RECIST criteria 2009).
SECONDARY OBJECTIVES:
I. Determine the best overall response (as per the revised RECIST criteria 2009).
II. Determine the 1- and 2-year progression-free survival. III. Determine the 1- and 2-year overall survival. IV. Assess GDC-0449 safety. V. Conduct a pharmacogenomic analysis of predictive markers of treatment outcome.
OUTLINE: This is a multicenter study.
Patients receive oral Hedgehog antagonist GDC-0449 on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicities.
Tumor samples are analyzed for correlative, including biomarker, studies.
After completion of study therapy, patients are followed up every 3 months.
