I. To determine the response rate to treatment with OSI-906 (linsitinib) 150mg BIO in patients with advanced wild-type (WT) gastrointestinal stromal tumor (GIST).
I. To determine the clinical benefit rate (stable disease [SD] >= 9 months, partial response [PR], or complete response [CR]) in patients with advanced WT GIST treated with OSI-906.
II. To determine the response duration, progression free survival, and overall survival in patients with advanced WT GIST treated with OSI-906.
III. To determine the tolerability and adverse event profile of OSI-906 in patients with advanced GIST.
IV. To explore patterns of protein expression in serum and tumor tissues as predictors of response and progression-free survival (PFS) in advanced WT GIST treated with OSI-906.
V. To evaluate the metabolic response to OSI-906 using fludeoxyglucose F 18 (FDG)-positron emission tomography (PET).
VI. To determine if tumor metabolic response correlates with anatomic response and clinical benefit.
VII. To measure changes in tumor metabolism by FDG-PET qualitatively and semi-quantitatively with standard uptake value (SUV) and tumor body ratio (TBR) from baseline to first computed tomography (CT)-response evaluation and correlate the findings with size changes as defined by conventional cross-sectional imaging scans.
VIII. To investigate correlations between glucose, insulin, and candidate tumor tissue and blood biomarkers with FDG-PET metabolic response.
Patients receive linsitinib orally (PO) twice daily (BID) on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up for 30 days, every 12 weeks for 2 years, and then annually thereafter.

- Failure-free Survival [ Time Frame: Up to 37 weeks ]Analyzed using Kaplan-Meier curves for the all treated and per protocol populations.
- OS [ Time Frame: Up to 37 weeks ]Analyzed using Kaplan-Meier curves for the all treated and per protocol populations.
- PFS [ Time Frame: Time from date of enrollment to time of progression or death due to any cause, assessed up to 37 weeks ]Analyzed using Kaplan-Meier curves for the all treated and per protocol populations.
- Response Duration [ Time Frame: Up to 37 weeks ]Analyzed using Kaplan-Meier curves for the all treated and per protocol populations.
- Time to Progression [ Time Frame: Up to 2 years ]Evaluated using cumulative incidence.
