Active clinical trials for "Gastrointestinal Stromal Tumors"

Participants with gastrointestinal stromal tumors(GIST) were divided into favorable and unfavorable sites according to the anatomical site of the tumor, and this study aims to validate the overall postoperative morbidity and mortality rates between favorable site receiving laparoscopic resection of GIST and that of unfavorable site under the currently standard surgical therapy.

The genetic background for cancer treatment may also be different among different areas and races. There is lack of Taiwanese data of genetic alterations in cancer patients. To understand the landscape of genetic aberrations of cancer in Taiwan, large scale survey of the cancer patients is indicated. In this pilot study, the investigators want to evaluate the landscape of genetic aberrations in cancer patients via oncopaenl test and collect the clinical data of the patients. The result of the oncopanel test will be returned to patient and their attending physician for reference of their further treatment. In addition, the investigators want to correlate the clinical outcome with the genetic aberrations of the cancer patients in Taiwan. Gastrointestinal stromal tumor (GIST) is a rare cancer compared with the other solid tumors. C-KIT or PDGFRA mutation is found in approximately 85-90% of GISTs. Imatinib, a tyrosine kinase inhibitor targeting c-KIT, has been used to treat advanced GIST successfully since 2000. However, resistance to imatinib may develop either via secondary mutation of c-KIT or primary resistance to those with wild type c-KIT and PDGFRA. Although sunitinib and regorafenib have been approved as second and third line of treatment for advanced GIST, the progression free survival were only 6.8 and 4.8 months, respectively. The genetic landscape of GIST with wild type c-KIT and PDGFRA was less studied. In the current study, the investigators want to focus on the GISTs with wild type c-KIT and PDGFRA to perform the NGS oncopanel for these patients. Then the investigators can understand the genetic aberrations of these patients (wild type GIST) and help for searching the potential treatment targets to them.

The purpose of this study is to investigate the feasibility of using ctDNA to support cancer diagnosis and risk stratification where invasive aerosol generating testing (and/or tissue biopsy) is challenging due to infection risk, technical impracticalities and resource limitations, such as during the COVID-19 pandemic and the subsequent recovery period.

An observational, multicenter study will be performed. Regular 3-12 monthly follow-up by CT-scan will be compared to results of ctDNA analysis. Blood for analysis of mutation in ctDNA will be collected at the same moment a CT-scan is performed. All samples will be analyzed at the reference Pathology laboratory at the UMCG. A part of the samples will also be analyzed in other institutions to implement the ddPCR. Primary endpoint is concordance between CT-scan and ctDNA analysis results, from which the negative predictive value (NPV) of our ddPCR assay will be calculated.

This is an open label, multi-center, phase II study of BBI503 administered to adult patients with advanced gastrointestinal stromal tumor who have exhausted all currently approved standard anti-cancer treatment options. BBI503 will be administered orally, daily, in continuous 28-day cycles at a dose of 300 mg once daily. Cycles will be repeated until patients are no longer clinically benefiting from therapy due to disease progression, adverse events, or another discontinuation criterion. Safety, tolerability and efficacy of BBI503 will be assessed for the duration of study treatment.

IPI-504-06 is a Phase 3, randomized, double-blind, placebo-controlled, multi-center study to evaluate the efficacy and safety of IPI-504 as compared to placebo in patients with metastatic and/or unresectable GIST following failure of at least imatinib and sunitinib. Approximately 195 patients will be randomized using a 2:1 ratio to receive either IPI-504 (N=130) or placebo (N=65). Upon unblinding, patients receiving either IPI-504 or placebo may receive IPI-504 in the open-label portion of the study if defined inclusion criteria are met. Early and frequent imaging timepoints (Weeks 2, 5, 8, 14 and every 6 weeks thereafter) are incorporated into this study to capture progression events and limit patient exposure to ineffective agents.

RATIONALE: Imatinib mesylate and sunitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. PURPOSE: This phase I trial is studying the side effects and best dose of imatinib mesylate given together with sunitinib in treating patients with gastrointestinal stromal tumors.

This randomized phase III trial studies imatinib mesylate and bevacizumab to see how well they work compared to imatinib mesylate alone in treating patients with gastrointestinal stromal tumor that has spread to other parts of the body or cannot be removed by surgery. Imatinib mesylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as bevacizumab, may interfere with the ability of tumor cells to grow and spread. It is not yet known whether imatinib mesylate and bevacizumab are more effective than imatinib mesylate alone in treating gastrointestinal stromal tumor.

Randomized phase III trial to compare the effectiveness of two different doses of STI571 in treating patients who have metastatic or unresectable gastrointestinal stromal tumor. STI571 may interfere with the growth of tumor cells and may be an effective treatment for cancer. It is not yet known which dose of STI571 is more effective in treating gastrointestinal stromal tumors.

to evaluate the clinical efficacy, safety and predictive factors of ripetinib in Chinese patients with advanced GIST in the real world
