Filter by: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.
The presence of c-kit mutation is an independent poor prognostic factor for relapse in addition to large size (> 5 cm) and high mitotic rate (> 5/50 high power field [HPF]) in localized gastrointestinal stromal tumor (GIST) patients who underwent complete surgical resection. In addition, the localized GIST which had exon 11 c-kit mutation and features of high-risk for relapse according to National Institute of Health (NIH) consensus guideline (tumor size > 10 cm or mitotic count > 10/50 HPF) also have high-risk of relapse. Until recently, there has been no effective therapy for advanced, unresectable GISTs. However, a new agent, imatinib mesylate, has shown promise in the metastatic setting, and c-kit exon 11 mutation is the strongest prognostic factor for better response and survival. It is reasonable to try imatinib in an earlier and minimal residual status especially for patients at higher risk of relapse and a higher probability of response to imatinib.
The primary objectives of the study are: - Determine the safety and maximum tolerated dose (MTD) of IPI-504 in GIST and STS patients who have failed prior therapies - Recommend a dose for subsequent studies of IPI-504
This phase II trial is studying how well sorafenib works in treating patients with malignant gastrointestinal stromal tumor that progressed during or after previous treatment with imatinib mesylate and sunitinib malate. Sorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.
The purpose of the study is to evaluate the safety and efficacy of AMG 706 in patients with gastrointestinal stromal tumor that have not been controlled while taking imatinib mesylate.
In the core study, participants with unresectable or metastatic gastrointestinal stromal tumors expressing c-kit were treated with either 400 mg or 600 mg imatinib mesylate for 3 years. The 10 year extension study allowed participants, who successfully completed the core study, to continue study treatment with imatinib mesylate provided they still benefited from treatment and did not demonstrate safety concerns as per the investigator's opinion.
This is a extension study of CSTI571B1201 study
This is a multicenter, post-marketing, clinical study evaluating the safety and efficacy of postoperative adjuvant therapy with Imatinib Mesylate in high-risk patients after curative resection of newly diagnosed GIST.Patients will be evaluated for relapse -free survival as measured by the confirmation of tumor recurrence and survival for 3 years after surgery for their primary tumors.
To evaluate the antitumor activity of SU011248 in advanced, imatinib mesylate-resistant gastrointestinal stromal tumor (GIST) when administered on a continuous daily dosing schedule
This study is an open-label, multicenter, Phase I dose-escalation study of the combination of AMN107 and imatinib (STI571) in patients with imatinib-resistant GIST. This study is designed to determine the Phase II dose of AMN107 and imatinib when administered together in patients with imatinib-resistant GIST, and to characterize the safety, tolerability and pharmacokinetic (PK) profile of this combination.
