Active clinical trials for "Gastrointestinal Stromal Tumors"

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 aim of this study is to demonstrate that the use of Gleevec in initially non-resectable gastrointestinal stromal tumors can lead to allow complete resection in 20% of cases.

LSG is thought to be the best choice for obese patients with conincidental GISTs, as a tumour can be resected along with resecting the stomach within the same procedure. The primary endpoint is that, how much does GIST suppose to be far from a staple line to do safe laparoscopic sleeve gastrectomy

To assess anti-tumor activity of avelumab in combination with axitinib in patients with unresectable/metastatic GIST after progression on second or third line treatment (after failure on at least of imatinib and sunitinib) in terms of progression-free survival (PFS)

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: 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 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.

Prospective observational trial. A full thickness resection of gastric subepithelial tumors is performed after application of full thickness sutures underneath the tumor with the GERDX(TM) device. Hypothesis: This endoscopic method is feasible, effective and safe.

This is an open label, multi-center, and randomized phase II trial designed to compare the safety and efficacy of direct oral anticoagulants and subcutaneous dalteparin in patients with acute venous thromboembolism and upper gastrointestinal, hepatobiliary, or pancreatic cancer, based on a group sequential design. Enrolled patients will be randomized in a 1:1 ratio. Patients will be stratified by performance status, type of cancer, chemotherapy and medical centers.

This is a non-randomized, open-label, multicenter phase 2 study to evaluate the efficacy and safety of ponatinib in patients with metastatic and/or unresectable GIST after prior failure or intolerability of imatinib. Patients will be enrolled into 1 of 2 cohorts based on absence (Cohort A) or presence (Cohort B) of KIT exon 13 resistance mutations as measured by liquid biopsy. A third cohort (Cohort C) will include patients who have received all approved lines of TKI treatments (imatinib, sunitinib and regorafenib).

The purpose of this study is to determine the efficacy and safety of endoscopic submucosal tunnel dissection (ESTD) compared with video-assisted thoracoscopic surgery (VATS) in the treatment of upper gastrointestinal submucosal tumors.

RATIONALE: Imatinib mesylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known which dose of imatinib mesylate is more effective in treating gastrointestinal stromal tumor. PURPOSE: This randomized phase III trial is studying two different doses of imatinib mesylate to compare how well they work in treating patients with unresectable or metastatic gastrointestinal stromal tumor.
