Filter by:Funding Source - FDA OOPD FDA-approved products for patients with unresectable or metastatic GIST include therapies such as imatinib and sunitinib. Although there are FDA-approved products for the treatment of advanced/metastatic GIST, these therapies are known to be ineffective in the SDH-mutant/deficient subtype and no known effective therapies exist. The purpose of this study is to investigate SDH-Mutant/Deficient Gastrointestinal Stromal cancer's response to the drug Temozolomide (TMZ) and aim to improve patient outcomes. Temozolomide is approved by the FDA for the treatment of newly diagnosed glioblastoma multiforme (GBM) and refractory anaplastic astrocytoma cancers. Temozolomide is considered experimental because it is not approved by the FDA for the treatment of SDH-Mutant/Deficient Gastrointestinal Stromal Tumor.
Assessment of the efficacy and safety of Regorafenib and Avelumab in patients with advanced or metastatic solid tumors (ten cohorts), once the Recommanded Phase II Dose (RP2D) has been determined (phase I trial). Assessement of the efficacy and safety of a low-dose of regorafenib (80mg/day) with avelumab in patients with advanced or metastatic colorectal tumors.
This is an open-label, randomized, Phase 3 study in patients with locally advanced unresectable or metastatic GIST (advanced GIST) of avapritinib (also known as BLU-285) versus regorafenib in patients previously treated with imatinib and 1 or 2 other TKIs.
To compare the efficacy of surgery followed by sunitinib with surgery followed by imatinib in GIST patients with progression on imatinib;To investigate the optimal therapy after surgery in GIST patients with focal or multifocal progression in imatinib
Data are currently insufficient to guide the management of very small gastrointestinal stromal tumors（GISTs）（< 2 cm) discovered incidentally on endoscopy,this study is designed to collect the medical records of patients in different treatment group with long-term follow-up data,and attempts to evaluate the usefulness of regular endoscopic ultrasound（EUS）surveillance and the necessity,safety and feasibility of endoscopic submucosal dissection（ESD）for small GISTs,thus provide evidence for the revision of the guideline.
NOTE: This is a research study and is not meant to be a substitute for clinical genetic testing. Families may never receive results from the study or may receive results many years from the time they enroll. If you are interested in clinical testing please consider seeing a local genetic counselor or other genetics professional. If you have already had clinical genetic testing and meet eligibility criteria for this study as shown in the Eligibility Section, you may enroll regardless of the results of your clinical genetic testing. While it is well recognized that hereditary factors contribute to the development of a subset of human cancers, the cause for many cancers remains unknown. The application of next generation sequencing (NGS) technologies has expanded knowledge in the field of hereditary cancer predisposition. Currently, more than 100 cancer predisposing genes have been identified, and it is now estimated that approximately 10% of all cancer patients have an underlying genetic predisposition. The purpose of this protocol is to identify novel cancer predisposing genes and/or genetic variants. For this study, the investigators will establish a Data Registry linked to a Repository of biological samples. Health information, blood samples and occasionally leftover tumor samples will be collected from individuals with familial cancer. The investigators will use NGS approaches to find changes in genes that may be important in the development of familial cancer. The information gained from this study may provide new and better ways to diagnose and care for people with hereditary cancer. PRIMARY OBJECTIVE: - Establish a registry of families with clustering of cancer in which clinical data are linked to a repository of cryopreserved blood cells, germline DNA, and tumor tissues from the proband and other family members. SECONDARY OBJECTIVE: - Identify novel cancer predisposing genes and/or genetic variants in families with clustering of cancer for which the underlying genetic basis is unknown.
Endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNA) is a reliable, safe, and effective technique for obtaining samples from the GI wall lesions and from organs adjacent to the GI tract (pancreas, nodes...).Needles available for EUS-FNA include 25G, 22G and 19G. Some studies have suggested that the 25G needle could be equal or even better than the 22G needle. The BXN system and neddles are is a newly developed for EUS-FNA. This trial is developed for testing the accuracy of the new neddle system for EUS-FNA and for comparing the two needles types, 25G and 22G.
Background: -Some people with wild-type gastrointestinal stromal tumors (WT-GIST) have a deficiency in one of their proteins called succinate dehydrogenase (SDH). Vandetanib is a cancer drug that has been approved to treat thyroid cancer and has been used with some success in other tumors that have a similar loss of SDH. Researchers want to see if this drug can also decrease tumor growth in people with WT-GIST. Objectives: -To test whether the study drug will benefit people with WT-GIST. Eligibility: -Adults and children 3 years old and older with WT-GIST. Design: - Researchers will test participants tumor tissue to confirm it is the wild type of GIST. - Participants will be screened with a medical history, physical exam, and blood tests. They will also have electrical recording of the heart (Eastern Cooperative Oncology Group (ECOG)) and scans of the tumor. - Participants will take the study drug in 28-day cycles. Their doctor will decide how many cycles they can complete. - They will take the study drug once every day and record it in a diary. - On Day 14, they will also visit their doctor to look for side effects. - Before cycles 2, 3 and 4, participants will have a physical exam, urine tests, blood pressure check, and blood tests. These tests will then be done periodically for as long as they are in the study. - Before cycle 4, scans will be done to check the size of the cancer. Most of these will be repeated every 3-6 cycles. - When they stop taking the study drug, participants will return to the clinic for a physical exam and blood tests.
The purpose of this study is to evaluate the efficacy and safety of ponatinib in participants with metastatic and/or unresectable gastrointestinal stromal tumor (GIST) following failure of prior tyrosine kinase inhibitor (TKI) therapy.
This study focuses on four different lesions: pancreatic cysts, lymph nodes near the gastrointestinal tract, pancreatic masses and GIST tumors. On one hand, the results obtained during previous studies are more advanced for the assessment of the diagnostic performance of Cellvizio needle-based Confocal Laser Endomicroscopy (nCLE) system for Pancreatic cysts. Safety and technical feasibility have already been performed, and an interpretation criteria classification exists. On the other hand, results for pancreatic masses, Lymph nodes and GIST are less developed. the objectives of the study are to - Assess the diagnostic performance of the Cellvizio needle-based Confocal Laser Endomicroscopy (nCLE) system in diagnosing masses and cystic tumors of the pancreas, lymph nodes, submucosal lesions of the GI tract - Define/Validate descriptive criteria of nCLE sequences in masses and cystic tu-mors of the pancreas, lymph nodes, submucosal lesions of the GI tract
