Filter by:The purpose of this trail is to evaluate the performance of Genetron D842V PCR kit in GIST patients using real-time PCR method.
The purpose of this study is to investigate the effect of multiple dosing of avapritinib on the pharmacokinetics (PK) of midazolam in adult patients with metastatic or unresectable gastrointestinal stromal tumors (GIST), recurrent gliomas, or other KIT mutant tumors.
This is a multi-institutional retrospective study in order to identify the most relevant and advisable features of follow-up, and to explore its impact on principal clinical outcomes. Moreover, a dedicated effort will be pursued to identify the peculiar characteristics (if any) of patients that experienced recurrence of the disease. The study will collect data about patients affected by primary GIST at very-low and low risk of recurrence/progression, referred to participating Institutions between January 2000 and February 2020
Background: Long-term or life-long oral targeted therapy might also increase patients' distress, influencing patients' cognitive and life activity function, medication adherence and related care needs. However, very limited information has been known about patients' experiences. Purpose: First, to examine the changes of perceived physical and psychological distress, functional status, medication adherence, and unmet care needs; and second, to identify factors related to the changes of patients' medication adherence and unmet care needs by generalized estimating equation (GEE). Methods: This is a two-phase study. Phase I is a cross-sectional survey study, and the second phase is a 1-year follow-up prospective longitudinal study. Eligible subjects are CML and GIST patients newly taking oral targeted therapy. Patients will be assessed before taking the first targeted therapy and 1st, 2nd, 3rd, 6th, 12th month (T1-T6, respectively). The patients were assessed of their (1) symptom severity, (2) psychological distress, (3) cognitive and life activity function, (4) adherence, (5) social support, (6) unmet care needs, and (7) background and disease-treatment information. Data will be analyzed mainly by GEE to identify the predictors (independent variables) of the changes in medication adherence and unmet care needs overall the 12 months, 6 time points. After the approval of IRB, research assistants in different data collection sites will be trained for maintaining the consistency and quality of data collection. Expected Outcomes and Future Implications: Although CML and GIST are not the most prevalent cancers in Taiwan, the investigators aim to use both groups of patients groups to examine the current status and changes of distress, adherence and care needs in patients are taking long-term or life-long TKI derived oral targeted therapy. From Phase II study, the changes of newly TKI targeted therapy takers' distress, adherence and care needs would be carefully and in-depth examined. It will provide health care professionals a more comprehensive picture of the changes in patients' distress, adherence, and care needs during taking oral targeted therapy. The results will also provide as a basis and evidence for better development a timing and comprehensive care models to fit and increase patients' life quality during receiving the most advanced targeted therapy.
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.
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
Retrospective correlation of clinical outcomes data with mutational status in GIST subjects treated with sunitinib.
This phase I trial studies the side effects and best dose of vaccine therapy in treating patients with metastatic solid tumors. Vaccines made from antibodies and peptides combined with tumor cells may help the body build an effective immune response to kill tumor cells.
