Filter by:The purpose of this study is to determine if contrast-enhanced ultrasound can detect abnormal features of kidney lesions in patients with Von-Hippel Lindau with the same accuracy as conventional ultrasound and contrast-enhanced magnetic resonance imaging (MRI)
The primary objective of this study is to assess the overall response rate (ORR) of von Hippel-Lindau (VHL) disease-associated clear cell renal cell carcinoma (ccRCC) tumors in VHL patients treated with PT2385.
Background: People with Von-Hippel-Lindau (VHL) disease may experience significant vision loss as a result of retinal capillary hemangiomas (RCH), the most common and often earliest manifestation of VHL. Objective: To investigate the safety and possible efficacy of combination investigational treatment with serial intravitreal injections of E10030, a PDGF-B antagonist, and ranibizumab, a VEGF-A antagonist, in participants with severe ocular VHL disease. Design: Three participants with severe ocular VHL disease will receive the combination investigational treatment in one eye and will be followed for 104 weeks. Primary Outcome: The safety of the combination investigational treatment, assessed by tabulation of adverse events reported through Week 52.
Background: - Von Hippel-Lindau (VHL) disease is a rare gene disease. People with VHL often have a brain tumor called hemangioblastoma. Standard treatment for these tumors is risky surgery. Researchers want to find new ways to treat people who have the tumors. They want to see if a drug that fights other cancers might slow the growth of hemangioblastomas in some people with VHL. Some people with VHL have mutations that make abnormal proteins. Tumors form in such people because the abnormal protein is broken down quickly. The cancer drug may work in these tumors by preventing breakdown of protein. Objective: - To study how the drug vorinostat affects hemangioblastomas in people with VHL. Eligibility: - Adults at least 18 old with hemangioblastomas from VHL. Design: - Participants must already be in study 03-N-0164. They must have tumor surgery scheduled. - Participants must stop taking most medications 14 days before surgery. - One week before surgery, participants will enter the hospital. They will be screened with medical history and physical and neurological exams. They will give blood and urine samples. Participants will have an electrocardiogram. For this test, small sticky patches are put on the arms, legs, and chest. Participants will lie still for a few minutes while a machine records heart rate and rhythm. - Participants will take one vorinostat by mouth each day for 7 days. - Participants will have blood drawn during the week to check for any side effects. - Participants will have their tumor removed in surgery. Researchers will study the tumor tissue for the effects of the study drug. - A nurse will call participants 1 month after surgery to check for side effects.
Background: - Neuroendocrine tumors (NETs) are rare but have been more common over the past decade. The only treatment for NETs is surgery, but most are found when they are too advanced for surgery. Researchers are looking for the best way to find NETs earlier, so that surgery can be successful. They want to test if the study drug can be used along with imaging devices to detect NETs. Objectives: - To see how well a new experimental imaging agent, 68Gallium-DOTATATE, detects unknown primary and metastatic NETs in the gastrointestinal system and pancreas. Eligibility: - Adults over 10 years old with a suspected NET or family history of NET. Design: - Participants will be screened with a medical history and physical exam, and have a blood test. - Participants will undergo three scans. For all of these, a substance is injected into their body, they lie on a table, and a machine takes images. - A standard computed tomography (CT) scan of the chest, abdomen, and pelvis. - An octreotide scintigraphy Single photon emission computed tomography (SPECT)/CT. - A 68Gallium-DOTATATE positron emission tomography (PET)/CT. The study drug is injected into a vein, usually in the arm. Low-dose X-rays go through the body. For about 40 minutes a large, donut-shaped device takes images of the body. The entire session takes 90 to 120 minutes. - Researchers will compare images from the three scans. - Participants will have 1 follow-up visit each year for 5 years. At this visit, they will have a medical exam, blood taken, and a CT scan.
This phase II trial studies the side effects and how well pazopanib hydrochloride works in treating patients with von Hippel-Lindau syndrome. Pazopanib hydrochloride may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
VHL patients may benefit from sunitinib. This study will investigate the following objectives : PRIMARY OBJECTIVE - To determine the objective response rate according to RECIST criteria, in VHL patients with advanced tumors or tumors untreatable by other means, and treated with sunitinib. SECONDARY OBJECTIVES - To evaluate the safety and tolerability of sunitinib in VHL patients according to the NCI-CTC criteria Version 3.0. - To determine the following time-to-event endpoints: overall survival, time to disease progression, progression free survival, time to response and duration of response. - To evaluate quality of life in VHL patients receiving sunitinib.
Von Hippel Lindau disease (VHLD) is an inherited syndrome characterized by vascular malformations, kidney cancer, adrenal gland and pancreas tumors. The VHL protein is not functional in the different disease associated lesions which results in production of high amounts of vascular endothelial growth factor (VEGF). Currently there are no clinical, radiographic or molecular markers that can predict the natural history of a given lesion. With 89Zr-bevacizumab positron emission tomography (PET) scanning, VEGF can be visualized and quantified. The investigators hypothesize that 89Zr-bevacizumab PET imaging is a useful tool to predict the behaviour of disease associated lesions in patients with VHLD. Adult patients with VHLD who have had routine magnetic resonance imaging (MRI) scans of central nervous system (CNS) and abdomen will undergo a 89Zr-bevacizumab PET scan. MRI will be repeated within 12 months.
This study will examine the effectiveness of an investigational drug called ZD6474 (also known as vandetanib or ZACTIMA). Vandetanib is an experimental drug that is designed to prevent the growth and development of new blood vessels on tumors and to prevent the direct growth of cancer cells. It has been tested in a number of clinical trials on adults with cancer, but the United States (U.S.) Food and Drug Administration has not specifically approved it as a cancer treatment. The purpose of this investigational study is to better understand how vandetanib affects humans who have kidney cancer related to von Hippel-Lindau (VHL) disease, and to develop tests that may improve researchers understanding of kidney cancer and its effects. Volunteers must be at least 18 years old and must have been diagnosed with kidney cancer related to VHL. Candidates must have a life expectancy greater than three months and must have at least one measurable renal tumor for study purposes. Candidates may not be receiving any other investigational agents or have been treated with an investigational drug within the past four weeks. Candidates who have had surgery, chemotherapy, or radiotherapy within the past four weeks will be excluded from the study. Candidates will be screened with a physical examination and medical history. During the study, participants will receive an oral dose of vandetanib once a day for 28 days (a treatment period known as a cycle). Participants will need to return to the National Institutes of Health every two weeks on the same day of the week as the first dose of vandetanib for a series of tests and procedures, including blood and urine tests and an electrocardiogram. Every 12 weeks, computerized tomography (CT) or magnetic resonance imaging (MRI) scans will be done to assess the size of participants tumors. Participants whose tumors do not grow and who do not have unacceptable side effects may continue to receive vandetanib to maintain the current condition, until researchers conclude the study....
The purpose of this study is to evaluate the safety and tolerability of intravitreal injections of ranibizumab in the treatment of AMD variants and other choroidal neovascularization (CNV) related conditions (Coats' disease, idiopathic perifoveal telangiectasia, retinal angiomatous proliferation, polypoidal vasculopathy, pseudoxanthoma elasticum, pathological myopia, multi-focal choroiditis, rubeosis iridis) using the incidence and severity of adverse events. Limited forms of treatment are available that limit the loss of visual acuity. However, the patients may not have any substantial improvement in acuity or function. Therefore there remains a significant unmet need for therapeutic options managing the neovascularization and its consequences. Lucentis (ranibizumab) injection will be considered as an attempt to control the growth of the abnormal vessels because of evidence suggesting that angiogenic factors, such as vascular endothelial growth factor (VEGF), play a role in the pathogenesis of neovascular non-AMD conditions. The rationale for the study design is as follows: A 0.5 mg dose of Lucentis (ranibizumab), a commercially available preparation that is Food and Drug Administration (FDA) approved and labeled for intravitreal injection use for neovascular (wet) age-related macular degeneration will be used. In AMD variants and other CNV related conditions, vascular endothelial growth factor (VEGF) plays a role in the pathogenesis as in neovascular AMD. Intravitreal injection of ranibizumab delivers maximal concentration of the antibody fragment to the vitreous cavity with minimal systemic exposure. The dosing schedule, based on considerations of the half-life and the clinical response in patients with neovascularization suggests that a 1-month interval is optimal.
