10 Clinical Trials for Various Conditions
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.
Von Hippel-Lindau (VHL) disease is an inherited syndrome manifested by a variety of benign and malignant tumors. Hemangioblastomas are the most common lesion associated with VHL disease affecting 60-84% of patients with a mean age at diagnosis of 29 years. Standard treatment for this disease is by surgery or radiotherapy. No approved systemic therapy yet exists. Patients with VHL have an increased growth factor production, specifically vascular endothelial growth factor (VEGF), resulting in angiogenesis (growth of blood vessels). Studies show that Bevacizumab inhibits the growth of VEGF protein and will block the VEGF-driven angiogenesis and result in stabilization and regression of hemangioblastomas in VHL disease patients. The dose of bevacizumab will be 10 mg/kg every two weeks for up to 6 months.
The purpose of this study is to determine whether PTK787/ZK 222584 is effective in treating hemangioblastoma of the brain and/or retina in patients with von Hippel-Lindau disease. The study will also assess safety and tolerability of PTK787/ZK 222584, and changes in markers of angiogenesis (new blood vessel growth).
Background: Retinal hemangioblastoma (RH) is a tumor. It grows from the retina in the eye. It can threaten a person s vision. Trans-scleral cryotherapy is used to destroy the tumors and minimize the long-term risks of vision loss. RH is a rare condition, often occurring in people with von Hippel-Lindau disease. There are no clinical trials to study how well the treatment works. Researchers want to study the medical records of people with RH who were treated at the NIH eye clinic to learn more. Objective: To analyze clinical data collected over a 20-year span to study consecutive cases of RH managed with trans-scleral cryotherapy at the NIH. Eligibility: People who took part in NIH natural history protocols for which cryotherapy of RH was performed as a standard care measure. Design: Researchers will collect and study data from participants medical charts. Participants will not be contacted because no new data is needed. Researchers were granted a waiver of informed consent for use of these medical records. To protect patient privacy, participants will be assigned an ID number. Their data will be entered into a spreadsheet in a coded fashion. The key to this code will be kept in a secure file. No patient identifying information will be used in the analysis or the publication....
The purpose of this study is to learn more about the growth of brain and spinal cord tumors and cysts that develop in association with them in patients with von Hippel-Lindau disease. It will examine how fast the tumors grow and try to determine what factors (for example, puberty , pregnancy, menopause, blood proteins, etc.) affect their growth. Patients between the ages of 8 and 75 years who are enrolled in NIH s study of von Hippel-Lindau disease may be eligible for this 5-year study. Participants will have magnetic resonance imaging (MRI) of the brain and spinal cord and a thorough neurological history and examination at the start of the study. A blood sample will be taken for analysis of factors (hormones or other proteins) that may predict tumor growth. Follow-up clinic visits every 6 months will include a physical and neurological examination, blood tests, and MRI scans of the brain and spine. If symptoms or tumor growth requires more frequent follow-up, scans will be done at 3-month intervals. Surgical removal of brain and spinal cord tumors is currently the treatment of choice when these lesions cause neurological problems. A better understanding of which tumors are likely to grow and which will remain stable may help guide physicians in treatment decisions and avoid unnecessary procedures.
The study population consists of patients who undergo resection for somatostatin receptor-positive (SSTR-positive) CNS tumors, focusing on meningioma, and including esthesioneuroblastoma, hemangioblastoma, medulloblastoma, paraganglioma, pituitary adenoma, and SSTR-positive systemic cancers metastatic to the brain, such as small cell carcinoma of the lung. The study indication is to determine the diagnostic utility of 68Ga-DOTATATE PET/MRI in the diagnosis and management of patients with SSTR-positive CNS tumors, specifically whether 68Ga-DOTATATE PET/MRI demonstrates utility distinguishing between tumor recurrence and post-treatment change. To date, the utility of Ga-68-DOTATATE PET/MRI in meningioma has not been explored. Investigators have over the past 3 months been able to accrue the largest case series of presently 12 patients in whom Ga-68-DOTATATE PET/MRI demonstrated utility in the assessment of meningioma, including assessment for postsurgical/postradiation recurrence, detection of additional lesions not visualized on MRI alone, and evaluation of osseous invasion. Based on this initial experience, investigators intend to study the impact of Ga-68-DOTATATE PET/MRI in the assessment of the extent of residual tumor in patients status post meningioma resection, specifically in patients in whom tumor location limits resectability, patients with World Health Organization (WHO) grade II/III disease, and patients with history of stereotactic radiosurgery (SRS) who develop postradiation change.
The purpose of this study is to find out what effects, good and/or bad, sunitinib has on patients and their tumors. At this time, no drugs are routinely used to treat meningioma, hemangioblastoma or hemangiopericytoma. Only surgery and radiation therapy are known to be useful. Sunitinib is a drug approved for advanced kidney cancer. Sunitinib is also being studied for other tumors. It may be useful in the treatment of brain tumors because it can prevent formation of new blood vessels that allow tumor cells to survive and grow.
The goal of this clinical research study is to learn if sunitinib malate (SU011248) can help to control VHL. The safety of this drug will also be studied. Primary objectives: * Evaluate safety of treatment with SU011248/sunitinib malate (50 mg daily dose for 4 weeks, then 2 weeks off) for 6 months in patients with Von Hippel-Lindau Syndrome (VHL) who have a measurable lesion undergoing surveillance Secondary objectives: * Evaluate efficacy of treatment with SU011248/sunitinib malate (50 mg daily dose for 4 weeks, then 2 weeks off) for 6 months in patients with VHL who have a measurable lesion undergoing surveillance Correlative objectives: * Evaluate quality of life of SU011248/sunitinib malate therapy in VHL patients * Evaluate peripheral blood lymphocyte receptor phosphorylation in VHL patients taking SU011248/sunitinib malate (optional procedure) * Correlate results of dynamic contrast-enhanced and diffusion weighted MRI and dynamic contrast enhanced CT with response and explore findings suggestive of surrogates of early response (optional procedure)
The goal of this clinical research study is to learn if dovitinib can safely be given to patients who have VHL with a measurable hemangioblastoma (tumor of the central nervous system). The effects of this drug on the disease will also be studied.
The von Hippel Lindau (VHL) gene has recently been identified as the genetic defect resulting in a syndrome of multiple neoplasias. Patients with VHL disease develop retinal angiomata, renal cysts and/or carcinomas, CNS hemangioblastomas as well as pancreatic cysts and pheochromocytomas. Investigators have shown the gene to be a tumor suppressor type proto-oncogene located at chromosomal locus 3p26. The gene includes three exons whose gene product targets a cellular transcription factor Elongin SIII. Binding of the VHL proteins to two subunits of this elongation factor inhibits transcription and may play a crucial role in the clinical development of the von Hippel Lindau phenotype.
