Active clinical trials for "Gastrointestinal Stromal Tumors"

RATIONALE: Vaccines may make the body build an immune response to kill tumor cells. Colony-stimulating factors such as sargramostim increase the number of immune cells found in bone marrow or peripheral blood. Combining vaccine therapy with sargramostim may cause a stronger immune response and kill more tumor cells. PURPOSE: This phase I trial is studying the side effects of vaccine therapy when given together with sargramostim in treating patients with advanced sarcoma or brain tumor.

This randomized phase III trial is studying imatinib mesylate to see how well it works compared to placebo in treating patients with primary gastrointestinal stromal tumor that has been completely removed by surgery. Imatinib mesylate may interfere with the growth of tumor cells and may be an effective treatment for patients with primary gastrointestinal stromal tumor that has been completely removed by surgery.

This study evaluates the combination of entacapone and imatinib in the treatment of gastrointestinal stromal Tumors who have progressed on the setting of at least Imatinib and Sunitinib. 5 participants will be included in this open-label observatory study.

This is a prospective, multicenter, observational real-world study to explore the Avapritinib therapy in GIST patients who definited Non-exon18 Mutations of PDGFRA.

The objective is to compare efficacy and safety of masitinib at 12 mg/kg/day to sunitinib at 50 mg/day in treatment of patients with gastro-intestinal stromal tumor resistant to imatinib.

Imatinib mesylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Perioperative imatinib mesylate may shrink the tumor and may reduce the chance of relapse after surgery. This phase II trial is studying the effectiveness of perioperative imatinib mesylate in treating patients with locally advanced gastrointestinal stromal tumor.

This randomized phase I/II clinical trial is studying the side effects and best dose of gamma-secretase/notch signalling pathway inhibitor RO4929097 when given together with vismodegib and to see how well they work in treating patients with advanced or metastatic sarcoma. Vismodegib may slow the growth of tumor cells. Gamma-secretase/notch signalling pathway inhibitor RO4929097 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving vismodegib together with gamma-secretase/notch signalling pathway inhibitor RO4929097 may be an effective treatment for sarcoma.

With discovery of KIT mutations and the advent of KIT tyrosine kinase inhibitor imatinib (GlivecTM, Novartis), there has been substantial improvement in overall survival in patients with advanced and/or metastatic gastrointestinal tumors (GIST). Recently, sunitinib (SuteneTM, Pfizer) showed activity as second-line therapy in GIST patients after failure with imatinib. However, virtually all patients will eventually progress or become intolerable after the first-line imatinib and the second-line sunitinib. Dovitinib (TKI258, Novartis) is a multi-kinase inhibitor. TKI258 is a potent inhibitor of the VEGFR 1, 2, and 3, FGFR1, 2 and 3, PDGFRβ, Kit, RET, TrkA, CSF 1R, and FLT3 with inhibitory concentration 50% (IC50s) of less than 40nM. Stem cell factor (SCF) also termed KIT ligand, or steel factor has been shown to modulate tumor angiogenesis. In cultured human endothelial cells and Kit expressing cancer cells, TKI258 inhibits VEGF- and SCF-stimulated mitogenesis. .

This is a Phase 1 multi-center study to assess the safety and efficacy of TGR-1202 as a single agent or in combination with nab-paclitaxel + gemcitabine or with FOLFOX in patients with select relapsed or refractory solid tumors.

This is a 2-arm, randomized, placebo-controlled, double-blind, international, multicenter study comparing the efficacy of ripretinib (DCC-2618) to placebo in patients who have received treatment with prior anticancer therapies. Prior anticancer therapies must include imatinib, sunitinib, and regorafenib (3 prior therapies). Approximately 120 patients were randomized in a 2:1 ratio to ripretinib 150 mg QD or placebo
