Filter by:RATIONALE: Drugs used in chemotherapy, such as irinotecan, fluorouracil, and leucovorin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of irinotecan when given together with fluorouracil and leucovorin in treating patients with advanced gastrointestinal cancer.
The mainstay of therapy for GISTs is surgical resection, however, recurrence is almost inevitable in high-risk tumors and secondary surgery or other salvage therapy has yielded poor outcome. The median survival for patients with unresectable or metastatic GIST is approximately 20 months, and for patients with local recurrence it is 9 to 12 months. Responses to chemotherapy have been at best 5%. The introduction of imatinib has dramatically changed the prognosis of these patients yielding response rates between 41% and 71% and an overall clinical benefit (tumor responses plus stable disease) ranging between 73% and 90%. However, resistance to imatinib may develop and represents a further clinical challenge. Sunitinib has recently been approved by the FDA for patients whose disease has progressed or who are intolerant to imatinib therapy. Patients with tumor progressing on sunitinib or another 2nd line agent have limited therapeutic alternatives. Reinstitution of imatinib, if possible, is considered an acceptable option for these patients because it may slow the rate of disease progression even in the setting of prior imatinib failure; however a more optimal 3rd line treatment is needed. AMN107 is a novel aminopyrimidine, available as an oral formulation that is ATP -competitive inhibitor of BCR-ABL,more potent than Imatinib. It inhibits proliferation and autophosphorylation of 32 out of 33 BCR-ABL point mutations. In addition AMN107 also inhibits PDGFRα,PDGFRβ, and KIT. Preliminary data from an ongoing Phase I study in imatinib-resistant GIST patients (CAMN107A2103) indicate that AMN107 alone (400 mg BID) and in combination with imatinib (imatinib 400 mg BID plus AMN107 200 mg QD and 400 mg QD) is well tolerated in this pre-treated patients.
This was a phase 1, open-label, multiple dose, single-arm study. The mixed bacteria vaccine (MBV) was administered at a starting dose of 250 EU (1 µL) and escalated in each subject to a dose inducing the desired pyrogenic effect, defined as a body temperature of 38°C to 39.5°C. The primary objective was to determine the safety profile of MBV in subjects with malignant tumors that expressed the NY-ESO-1 antigen and to identify the dose that induced the desired pyrogenic effect. Secondary objectives were to evaluate the immunological effects and tumor response of subjects following vaccination.
RATIONALE: Dasatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. PURPOSE: This phase II trial is studying how well dasatinib works as first-line therapy in treating patients with gastrointestinal stromal tumors.
This study will examine the response rate and the 6-month progression-free survival rates of subjects with advanced sarcoma treated with dasatinib.
This is a study using sunitinib for patients ending treatment on a previous sunitinib malate protocol to continue to receive sunitinib. The patient must have been enrolled in one of the following studies: A6181030, A6181064, A6181078, A6181087, A6181094, A6181107, A6181108, A6181110, A6181111, A6181112, A6181113, A6181120, A6181126 and A6181170. Other Pfizer sponsored sunitinib studies may be included in the future.
This phase I trial is studying the side effects and best dose of erlotinib hydrochloride when given together with cetuximab and to see how well they work in treating patients with advanced gastrointestinal cancer, head and neck cancer, non-small cell lung cancer, or colorectal cancer. Erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Erlotinib hydrochloride and cetuximab may also stop the growth of tumor cells by blocking blood flow to the tumor. Giving erlotinib hydrochloride together with cetuximab may kill more tumor cells.
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.
RATIONALE: Imatinib mesylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving imatinib mesylate before surgery may shrink the tumor so that it can be removed. PURPOSE: This phase II trial is studying how well imatinib mesylate works in treating patients with locally advanced gastrointestinal stromal tumor.
RATIONALE: Imatinib mesylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving imatinib mesylate after surgery may kill any remaining tumor cells. It is not yet known whether imatinib mesylate is more effective than observation only in treating gastrointestinal stromal tumor. PURPOSE: This randomized phase III trial is studying imatinib mesylate to see how well it works compared to observation only in treating patients who have undergone surgery for localized gastrointestinal stromal tumor.
