Filter by:This phase I/II trial studies the side effects and the best dose of selumetinib and how well it works in treating or re-treating young patients with low grade glioma that has come back (recurrent) or does not respond to treatment (refractory). Selumetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
A physical training program will improve quality of life, participation in physical activity, motor coordination, muscle strength, and bone and muscle strength in children with neurofibromatosis type 1.
This study is a prospective, randomized, double-blind, placebo-controlled evaluation of the safety of a topically applied formulation of rapamycin to cutaneous fibromatous lesions in subjects with Tuberous Sclerosis Complex (TSC) and Neurofibromatosis I (NF1). Subjects will apply either a Polyvinylidene fluoride (PVDF) coating (Skincerity) containing rapamycin or the PVDF coating alone nightly to fibromatous lesions for a duration of six months. The primary goal of this study is to evaluate the safety of the topical product in patients with TSC and NF1. The secondary goal of this study is to evaluate the effectiveness of the topical product for treatment of cutaneous fibromatous lesions.
The purpose of this study is to determine if Lapatinib has any effect on tumors found in patients with Neurofibromatosis Type 2 (NF2). NF2 is a condition that mainly affects the skin and nervous system. It causes non-cancerous tumors (which are known as neuromas) to grow on the nerves around a person's body. Some signs of NF2 include a gradual loss of hearing and tumors growing on the skin, the brain and the spinal cord which can lead to complications. Lapatinib is an oral drug that is approved by Food and Drug Administration (FDA) for other types of tumors, it is not approved by the FDA for treatment of NF2 related tumors. The investigators know a lot about how well it is tolerated, but the investigators do not know if it is effective in treating your condition, therefore it is considered to be an investigational medication. This study will test whether Lapatinib may shrink tumors commonly found in patients with NF2 or stop them from growing. This will help us to decide if Lapatinib should be used to treat NF2 patients in future. Lapatinib is a drug that has been used for over 10 years to treat various forms of cancer. It has not been studied for the treatment of tumors in NF2 patients.
Background: Neurofibromatosis Type 1 (NF1) is a genetic disorder in which patients are at increased risk of developing tumors (usually non-cancerous) of the central and peripheral nervous system. The disease affects essentially every organ system. The natural course of NFI over time is poorly understood. For most patients the only treatment option is surgery. A better understanding of NF1 may be helpful for the design of future treatment studies. Objectives: To evaluate people with NF1 over 10 years in order to better understand the natural history of the disease. To characterize the patient population and to examine how NFI affects patients quality of life and function. Eligibility: Children, adolescents, and adults with NF1. Design: Participants have a comprehensive baseline evaluation including genetic testing, tumor imaging, pain and quality-of-life assessments, and neuropsychological, motor and endocrine evaluations. Patients are monitored every 6 months to every 3 years, depending on their individual findings at the baseline study. Tests may include the following, as appropriate: - Medical history, physical examination and blood tests. - Whole body and face photography to monitor visible deformities. - Neuropsychological testing, quality-of-life evaluations, motor function tests, endocrinologic evaluations, heart and lung function tests, hearing tests, bone density scans and other bone evaluations. - MRI and PET scans to detect and assess plexiform neurofibromas (tumors that arise from nerves and can cause serious problems), paraspinal neurofibromas (tumors that arise from nerves around the spine and can cause problems by compressing the spinal cord), and malignant peripheral nerve sheath tumors (a type of cancer that arises from a peripheral nerve or involves the sheath covering the nerve). - Eye exams, MRI scans and PET scans to evaluate optic pathway gliomas (tumors arising from the vision nerves or the brain areas for vision) and the chemicals within the tumor and brain. - Eye exams and photographs to evaluate the development of Lisch nodules (non-cancerous tumors on the eye). - Photographs of dermal neurofibromas (tumors of the skin), cafe-au-lait spots (dark or pigmented areas on the skin that are often the first signs of NF1) and other skin problems. - Pain evaluations to monitor the different types of pain patients experience, causes of the pain, how often the pain occurs, effect of the pain on quality of life, and what pain medications and alternative treatments, such as acupuncture, are effective.
The purpose of this study is to determine whether multiple cutaneous neurofibromas in patients with neurofibromatosis type 1 can be removed with an erbium-YAG-laser.
Formation of new blood vessels (angiogenesis) is important for tumor growth in neurofibromatosis type 2 (NF2). It is known that tumors make a protein called vascular endothelial growth factor (VEGF) and there are higher levels of VEGF in the tumors and blood of many patients with NF2. VEGF stimulates the formation of blood vessels that supply the tumor with nutrients and oxygen. PTC299 is an oral drug that has been shown to decrease production of VEGF in animal models of human cancer. In these animal models, oral PTC299 administration decreases VEGF levels in the tumor and in the bloodstream, decreases blood vessel numbers in the tumor, and significantly slows or halts tumor growth. Safety studies in research animals indicate good tolerability at doses and drug levels that are higher than those planned for the clinical studies. Results from Phase 1a studies in healthy volunteers indicate that PTC299 achieves levels of PTC299 in the bloodstream that are known to be active in animal models of human tumor. This Phase 2 study is designed to test the hypothesis that PTC299 will be tolerable and will show evidence of VEGF reduction, antitumor activity, and hearing improvement when administered orally to patients with NF2.
This study will evaluate the feasibility of combining two drugs, Tarceva (an anti-EGFR agent), and Rapamycin (an mTOR inhibitor), in children with progressive low-grade gliomas who have failed initial conventional treatment. In addition to evaluating the toxicity of this drug regimen, the potential efficacy of the regimen will be assessed.
The purpose of this study is to determine if imiquimod cream can reverse the growth of neurofibromas. Imiquimod is a skin cream that works by stimulating the body's immune system to respond to tumors. Imiquimod cream is approved for use in patients with various skin lesions, including actinic keratosis, superficial basal cell carcinoma, and external genital warts. Information from these studies, as well as previous laboratory studies, suggest that imiquimod cream may help shrink neurofibromas or keep them from growing.
Tumors can grow on the auditory nerves and can cause hearing loss. A common type of tumor that does this is a vestibular schwannoma (VS), or acoustic neuroma. These tumors are not cancerous. Most often, people have only one VS. Occasionally, people have more than one VS and may have a condition called neurofibromatosis type 2 (NF2). Because VS can cause hearing loss, many people with VS will have treatment to preserve their hearing. This treatment usually involves surgery or radiation therapy. There are risks to these procedures, and sometimes they do not work to prevent hearing loss. Because surgery and radiation have risks and are not able to help everyone with VS, other methods of treatment are being explored. One area of exploration is looking to see if there is a drug that can be taken that might prevent the VS from growing larger and causing hearing loss, and might possibly even cause the VS to shrink in size. This study is exploring whether a drug that is approved by the FDA and is currently used to treat breast cancer might also work to treat VS. This study will measure the amount of drug that travels from the bloodstream and arrives at the tumor. This drug is safe and has few side effects. If this drug is shown to reach the tumor, it might be used in the future to treat VS without needing surgery or radiation. This study is recruiting people who are having surgery for VS. If you are going to have surgery to treat a VS, you may be eligible to participate.
