Filter by:Retrospective correlation of clinical outcomes data with mutational status in GIST subjects treated with sunitinib.
With discovery of KIT mutations and the advent of KIT tyrosine kinase inhibitor imatinib (GlivecTM, Novartis), there has been substantial improvement in overall survival in patients with advanced and/or metastatic gastrointestinal tumors (GIST). Recently, sunitinib (SuteneTM, Pfizer) showed activity as second-line therapy in GIST patients after failure with imatinib. However, virtually all patients will eventually progress or become intolerable after the first-line imatinib and the second-line sunitinib. Dovitinib (TKI258, Novartis) is a multi-kinase inhibitor. TKI258 is a potent inhibitor of the VEGFR 1, 2, and 3, FGFR1, 2 and 3, PDGFRβ, Kit, RET, TrkA, CSF 1R, and FLT3 with inhibitory concentration 50% (IC50s) of less than 40nM. Stem cell factor (SCF) also termed KIT ligand, or steel factor has been shown to modulate tumor angiogenesis. In cultured human endothelial cells and Kit expressing cancer cells, TKI258 inhibits VEGF- and SCF-stimulated mitogenesis. .
The objective of this study is to evaluate the effect of a perioperative nutrition strategy using oral nutritional supplements (ONS) on postoperative complications and improvement in body weight in malnourished patients who underwent gastrectomy.
The purpose of this study is to collect and store normal and malignant tissue from patients with gastric cancer, GIST, esophageal cancer, pancreas cancer, hepatocellular cancer, biliary cancer, neuroendocrine, peritoneal mesothelioma, anal cancer and colorectal cancer, an estimated 50 to 100 of each tumor type. To collect and store blood samples from patients with gastric cancer, GIST, esophageal cancer, pancreas cancer, hepatocellular cancer, biliary cancer, neuroendocrine, peritoneal mesothelioma, anal cancer and colorectal cancer. To create a database for the collected tissue and allow access to relevant clinical information for current and future protocols. To create tissue microarrays for each gastrointestinal cancer subtype, namely, gastric cancer, GIST, esophageal cancer, pancreas cancer, hepatocellular cancer, biliary cancer, neuroendocrine, peritoneal mesothelioma, anal cancer and colorectal cancer, to facilitate future molecular studies. To grant access to Dr Kindler, Dr. Salgia, and Dr. Catenacci to this database (as it is being acquired) of the coupled patient tissue samples (normal and malignant) and relevant clinical information for the investigation of tyrosine kinases, such as Met and Ron, receptor tyrosine kinase family members, STATs, paxillin, focal adhesion proteins, cell motility/migration proteins, tyrosine/serine/threonine kinase family members, related molecules, and downstream targets implicated in the pathogenesis of GI cancers. Examples of molecular testing include evaluation of DNA mutation, alternative splice variants, protein expression and phosphorylation, and immunohistochemistry on samples. These studies will be correlated with clinical information as stated above.
This is a multicenter, non-randomized, single agent, Phase II study of AUY922 in patients with refractory Gastrointestinal Stromal Tumor (GIST). The primary endpoint of this study is to determine progression-free survival (PFS) for patients with GIST receiving AUY922 intravenously (IV) on Days 1, 8, and 15 of a 21-day treatment cycle with restaging at 6 and 12 weeks and then every 9 weeks thereafter. Patients may continue treatment until evidence of disease progression.
It is well known that substantial interindividual variability of CYP3A4/1A2-phenotype activity is an important contributor to individual differences in the sensitivity to the frequently used tyrosine kinase inhibitors sunitinib and erlotinib. This study tests the potential for CYP-phenotyping to predict individual pharmacology and derive dosing algorithms for more tailored treatment of these drugs.
Children and young adults with gastrointestinal stromal tumors (GIST) will be treated with sunitinib. The safety (including pharmacokinetics) and tolerability of sunitinib will be studied in these patients. In addition, tumor responses and overall survival will be assessed.
This study is being done to gather information about the safety (any harmful effects) and effectiveness (usefulness) of Pazopanib in the treatment of Gastrointestinal Stroma Tumors (GIST) that cannot be treated by surgery or has spread to other organs. The Food and Drug Administration (FDA) have approved Pazopanib for the treatment of advanced kidney cancer but it is not approved for the treatment of GIST. The investigators hope to learn about the safety and usefulness (effectiveness) of Pazopanib for patients with GIST. Primary Objective: Non-progression rate based on RECIST criteria (CR+PR+SD) Secondary Objectives: - Response per Choi criteria - 6 month progression-free survival - Safety and tolerability
A Phase II Study of AUY922, Novel HSP Inhibitor, in Patients with Advanced GIST Failed to or Intolerance of Imatinib and Sunitinib Therapy Primary endpoint: •The primary endpoint of this study is to assess disease control rate (complete response + partial response + stable disease≧4 months) of AUY922 in patients with advanced GIST failed to imatinib and sunitinib Secondary endpoints: - To determinate the objective response rate (ORR, complete response + partial response) - To determinate the time to tumor progression (TTP) - To evaluate the safety and toxicity profiles of AUY922 - To evaluate the pharmacokinetics profile of AUY922 in Taiwan GIST population - To access the pharmacodynamic effect of AUY922 on HSP client proteins in blood and tumor if feasible , i.e. HSP70, in Taiwan GIST population - To access the tissue biomarkers pre-treatment and 4wks post treatment if feasible, i.e. HSP70, c-KIT, PDGFRA mutation, ...etc in Taiwan GIST population Exploratory endpoints: •PET imaging; sSUVmax
The primary objectives are: Dose escalation: 1. To determine the MTD and DLT(s) of TH-302 when used in combination with sunitinib. Dose expansion: 1. To make a preliminary assessment of the efficacy of TH-302 in combination with sunitinib as determined by the response rate and the progression-free survival in subjects with advanced RCC treated at the RP2D 2. To assess the safety of TH-302 in combination with sunitinib and determine a recommended Phase 2 dose of the combination. The secondary objectives are: Dose expansion: 1. To make a preliminary assessment of the efficacy of TH-302 in combination with sunitinib as determined by stable disease or better rate, duration of response and overall survival in subjects with advanced RCC treated at the RP2D. The exploratory objective is: 1. To explore the association of serum hypoxia biomarkers with efficacy endpoints.
