11 Clinical Trials for Various Conditions
Background: * Most treatments for malignant pheochromocytomas/paragangliomas (PHEO/PGL) are palliative and multidisciplinary. Chemotherapy using the combination of cyclophosphamide, vincristine, and dacarbazine has been successfully utilized in the management of rapidly progressive metastatic PHEO, with more than 50% complete or partial tumor response and more than 70% complete or partial biochemical response. * Vascular endothelial growth factor (VEGF) expression and evidence of angiogenesis has been found in many PHEO/PGL, so it is plausible that interfering with VEGF signaling may result in anti-tumor activity in patients with PHEO/PGL. * Axitinib (AG-013736) is an oral, potent and selective inhibitor of vascular endothelial growth factor (VEGF) receptors 1, 2, and 3. Pre-clinical data suggests that the anti-tumor activity of axitinib may result from its anti-angiogenic activity and that this is reversible when treatment is discontinued. * Given the known clinical safety and efficacy of axitinib, an assessment of its activity in PHEO/PGL and its impact on the VEGF pathway in PHEO/PGL could provide valuable information. Objectives: * Determine the response rate of metastatic PHEO/PGL to axitinib (AG-013736). * Determine the progression-free survival of metastatic PHEO/PGL treated with axitinib (AG-013736). * Explore the relationship of potential biological markers of axitinib activity with clinical outcomes. * Perform pharmacogenomics analyses of drug metabolism and transport proteins through germline deoxyribonucleic acid (DNA) examination. Eligibility: * Adults with a confirmed pathologic diagnosis of PHEO/PGL by the Laboratory of Pathology, National Cancer Institute (NCI) * Biochemical evidence of PHEO/PGL * Imaging confirmation of metastatic, locally advanced or unresectable disease. * Measurable disease at presentation * Eastern Cooperative Oncology Group (ECOG) performance status less than or equal to 2 * Patients must not have received prior therapy with a tyrosine kinase (TK) inhibitor Design: * Phase II, open label, non-randomized trial * Patients with metastatic pheochromocytoma/paraganglioma will receive axitinib (AG-013736 twice a day (BID)) in eight-week cycles * Patients will be evaluated for response every eight weeks using Response Evaluation Criteria in Solid Tumors (RECIST) criteria * Tumor biopsies are not mandatory but every attempt will be made to obtain these from patients prior to starting axitinib and again 20 - 30 days after treatment has begun. * Approximately 12 to 37 patients will be needed to achieve the objectives of the trial
This is an ongoing prospective Phase II clinical trial evaluating the efficacy of 131I-MIBG for the treatment of patients with metastatic or unresectable pheochromocytoma and related tumors.
This phase II trial studies how well the addition of olaparib to the usual treatment, temozolomide, works in treating patients with neuroendocrine cancer (pheochromocytoma or paraganglioma) that has spread from where it first started (primary site) to other places in the body (metastatic) or cannot be removed by surgery (unresectable). Poly (adenosine diphosphate \[ADP\]-ribose) polymerases (PARPs) are proteins that help repair deoxyribonucleic acid (DNA) mutations. PARP inhibitors, such as olaparib, can keep PARP from working, so tumor cells can't repair themselves, and they may stop growing. Chemotherapy drugs, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving olaparib with temozolomide may shrink or stabilize the cancer in patients with pheochromocytoma or paraganglioma better than temozolomide alone.
This phase II trial studies how well 177Lu-DOTATATE works in treating patients with rare endocrine cancers that have spread from where they started to nearby tissue or lymph nodes (locally advanced), spread to other places in the body (metastatic), or cannot be removed by surgery (unresectable). Radioactive drugs, such as 177Lu-DOTATATE, may carry radiation directly to cancer cells and not harm normal cells. 177Lu-DOTATATE may help to control endocrine cancers compared to standard treatment.
This phase II trial studies how well pembrolizumab works in treating patients with rare tumors that cannot be removed by surgery or have spread to other parts of the body. Monoclonal antibodies, such as pembrolizumab, may block specific proteins found on white blood cells which may strengthen the immune system and control tumor growth.
This pilot phase II trial studies how well cabozantinib s-malate works in treating patients with pheochromocytomas or paragangliomas that have spread from the primary site to other places in the body and cannot be removed by surgery. Cabozantinib s-malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking the growth of new blood vessels necessary for tumor growth.
This study is being conducted to evaluate whether the investigational drug Dovitinib, can shrink or slow the growth of cancer in patients with certain types of neuroendocrine tumors. This study will also further evaluate the safety of this drug.
RATIONALE: Temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as vinorelbine ditartrate, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving temsirolimus together with vinorelbine ditartrate may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of giving temsirolimus and vinorelbine ditartrate together in treating patients with unresectable or metastatic solid tumors.
RATIONALE: Hepatic arterial infusion uses a catheter to deliver anticancer substances directly into the liver. Drugs used in chemotherapy, such as melphalan, work in different ways to stop tumor cells from dividing so they stop growing or die. Giving drugs in different ways may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving an hepatic arterial infusion of melphalan together with hepatic perfusion works in treating patients with unresectable liver cancer.
RATIONALE: Radiolabeled octreotide can locate tumor cells and deliver radioactive tumor-killing substances to them without harming normal cells. PURPOSE: This phase I trial is to study the safety and effectiveness of radiolabeled octreotide in treating children who have advanced or refractory solid tumors.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of oxaliplatin with or without floxuridine and leucovorin in treating patients who have metastatic cancer of the peritoneum.
