Brief Summary

This phase II trial studies how well linsitinib works in treating younger and adult patients with gastrointestinal stromal tumors. Linsitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Detailed Description

PRIMARY OBJECTIVES:

I. To determine the response rate to treatment with OSI-906 (linsitinib) 150mg BID in patients with advanced wild-type (WT) gastrointestinal stromal tumor (GIST).

SECONDARY OBJECTIVES:

I. To determine the clinical benefit rate (CBR) (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 (PFS), and overall survival (OS) 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.

OUTLINE:

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.

Conditions

Carney Complex; Chondrosarcoma; Gastrointestinal Stromal Tumor; Paraganglioma

Eligibility Criteria

Inclusion Criteria

• Patients must have histologically confirmed gastrointestinal stromal tumor (GIST) with confirmed genotype of wild-type in a Clinical Laboratory Improvement Amendments (CLIA) certified laboratory
• Patients will be stratified into pediatric and adult cohorts; patients in the pediatric cohort (age at diagnosis =< 18 years OR diagnosis of Carney Triad or Carney-Stratakis Diad (paraganglioma, pulmonary chondroma) must have received at least sunitinib and have had progression on or intolerance to progression on therapy; patients in the adult cohort (age at diagnosis > 18 years AND no diagnosis of diagnosis of Carney Triad or Carney-Stratakis Diad) have had progression on or intolerance to imatinib therapy as documented by treating physician
• Performance status: Eastern Cooperative Oncology Group (ECOG) 0-2
• Patients must have measurable disease defined as lesions that can be measured in 2 dimensions by medical imaging techniques such as CT or magnetic resonance imaging (MRI); ascites, pleural fluid, and lesions seen on PET scan only are not considered measurable
• White blood cells count (WBC) >= 2.0 x 10^9/L (being >= 14 days off growth factors) OR
• Absolute neutrophil count (ANC) >= 1.5 x 10^9/L (being >= 14 days off growth factors)
• Platelet count >= 75 x 10^9/L
• Total bilirubin =< 1.5 times the upper limit of normal for age
• Alanine aminotransferase (ALT)/aspartate aminotransferase (AST) (serum glutamate pyruvate transaminase [SGPT]/serum glutamic oxaloacetic transaminase [SGOT]) =< 3 x the upper limit of normal (ULN) for the reference lab (=< 5 x the ULN for the reference lab in the presence of known hepatic metastasis, adjusted for age)
• Creatinine clearance > 70 ml/min/1.73m^2 or
• Serum creatinine < 1.5 x ULN per age and gender
• QT interval corrected using Frederica formula (QTcF) interval average of < 450 msec at baseline using the Frederica formula (QTcF)
• No concomitant drugs that prolong the QT corrected (QTc) interval
• No significant cardiac disease
• Fasting blood glucose < 150 mg/dL at baseline
• Hemoglobin A1C (HbA1c) < 7% at screening
• Patients or their legal representative must be able to read, understand and provide written informed consent to participate in the trial
• Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately; women of childbearing potential must provide a negative pregnancy test (serum or urine) within 7days prior to registration
• Patients with diabetes mellitus should have controlled disease on oral medications, defined as: no diabetic ketoacidosis (hyperglycemia, ketonuria, pH < 7.3 and bicarbonate < 15mEq/L) at the time of enrollment or within 30 days prior to enrollment and; no change in oral medications greater than 10% within 30 days prior to enrollment
• Patient must be able to swallow to participate in the study
• Signed informed consent
