42 Clinical Trials for Various Conditions
This is a study to gather some information on the safety and efficacy of the penetrating auditory brainstem implant (PABI) in patients with neurofibromatosis type 2.
Subjects with Neurofibromatosis Type 2 (NF2) and progressive vestibular schwannoma (VS) will be treated with crizotinib administered orally. Crizotinib will be taken continuously until disease progression or unacceptable toxicity, in continuous treatment cycles of 28 days each, for a maximum of 12 cycles.
In this research study the researchers want to learn more about the effects (both good and bad) the study drug selumetinib has on participants with neurofibromatosis type II (NF2) related tumor. The researchers are asking patients with NF2 related tumors to be in the study, because their hearing has decreased and/or their NF2 related tumor has started to grow. The goals of this study are: * Determine if selumetinib will stop NF2 related tumors from growing * Measure the changes in hearing after receiving selumetinib for 6 months. * Determine if selumetinib improves how participants feel (physically and emotionally) and how participants can perform daily activities. * Examine tumor tissue, if available, in a laboratory to see if NF2 related tumors have targets of selumetinib.
The goal of this clinical research study is to learn if the study drug AZD2014 can shrink growing or symptomatic meningiomas.
The aim of this study is to determine, whether the 3RP is feasible, accepted and efficacious and durable when delivered via Skype to patients with neurofibromatosis type 2 (NF2) who are deaf or have severe hearing loss using Communication Access Realtime Translation (CART) and/or American Sign Language (ASL). This will be a substudy of the IRB-approved protocol #2013P002605. It is the same study except it is looking at a particular sub-population: patients with NF2 who are hard of hearing.
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.
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 project will investigate the role of noise in the vestibular system, and in particular its effects on the variability (precision) of vestibular-mediated behaviors. The investigators will study vestibular precision in normal subjects and patients with peripheral vestibular damage, and will investigate its potential plasticity. The goals are to develop a better understanding of the role noise plays in the vestibular system in normal and pathologic populations, and to determine if the brain can learn to improve signal recognition within its inherently noisy neural environment, which would result in improved behavioral precision.
The aims of this study are to compare the effect and durability of two stress and symptom management programs tailored for patients with neurofibromatosis on quality of life and psychosocial functioning.
This is a phase II prospective, randomized, double-blind, longitudinal study evaluating whether the administration of aspirin can delay or slow tumor growth and maintain or improve hearing in VS patients.
This study tests the efficacy of an 8-week, Skype-based, group resiliency training intervention (The Relaxation Response Resiliency Program) for improving psychological stress in patients with Neurofibromatosis. A control group will receive a general health education curriculum. The investigators hypothesize that patients will improve on measures of psychological stress as a result of the resiliency program. A substudy (Unique Protocol ID: 2013P002605b) has been approved to test this study on a sub-population: patients with NF2 who are hard of hearing.
The NF Registry is a database of patient-reported symptoms, treatments, and experiences with their neurofibromatosis disease. It is a contact registry to relay clinical trial opportunities to targeted patient subgroups, and to supply de-identified disease data to researchers. It has the potential to become a natural history resource.
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.

This is a two-staged, Phase 2/3, randomized, multi-center study to investigate the efficacy and safety of REC-2282 in patients with progressive NF2 mutated meningiomas.
The purpose of this study is to determine if the study drug, AXITINIB, has any effect on tumors found in patients with Neurofibromatosis Type 2 (NF2).
The purpose of this research study is to determine whether Auditory Brainstem Implant (ABI) can improve hearing in children who are deaf and cannot receive a cochlear implants.
The purpose of this research study is to determine whether Auditory Brainstem Implant (ABI) can improve hearing in persons who are deaf in both ears and are not candidates for cochlear implants.
This trial studies whether Everolimus is efficacious in treating neurofibromatosis 2.
People who have neurofibromatosis type 2 (NF2) can have tumors that grow on the auditory nerves and cause hearing loss. These tumors are called vestibular schwannomas (VSs), or acoustic neuromas. People with NF2 can also get schwannomas in other parts of their body, as well as tumors called meningiomas and ependymomas. Because VSs can cause hearing loss, many people with NF2 will have treatment to preserve their hearing. This treatment usually involves surgery. Because surgery has risks and is not able to help everyone with VSs, 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 VSs from growing larger and causing hearing loss or brainstem compression. This study is exploring whether a drug that is approved by the FDA and is currently used to treat other tumors might also work to treat VSs. Based on people who have taken this drug to treat VSs already, there is some reason to think that it might be helpful to certain people with NF2. People enrolled in this study will receive the drug one time every three weeks for one year by infusion. This study will follow subjects over the course of the year that the person is taking the drug and for six months after the drug is stopped. This study is recruiting people who have NF2 and are currently having symptoms of tinnitus, dizziness, and/or hearing loss from their VSs. If you have NF2 and are currently having symptoms caused by your VSs, you may be eligible to participate.
Objective With this prospective natural experiment trial on neurofibromatosis type 2 (NF2) study, we hope to understand the factors leading to tumor progression and neurological disease burden in NF2. Study Population A total of 269 participants, ages 8-75, with a clinical or genetic diagnosis of NF2 will participate in this study. Design Study participants will be evaluated with a thorough physical and neurologic examination upon enrollment. This initial outpatient evaluation will include magnetic resonance imaging with contrast of brain and spine and blood collection for research use. Participants with measurable hearing will have audiology assessment performed. Participants with untreated vestibular schwannomas will have vestibular assessment performed during the initial visit. Genetic studies performed outside will be acceptable as confirmation of NF2 in enrolled patients. If needed to confirm NF2 with genetic studies, or for research purpose, whole genome/whole exome sequencing may be performed on blood obtained from subjects enrolled in this study. All participants will be evaluated by a speech language pathologist. Subjects will be followed as outpatients for up to ten years, during which clinical, and radiologic evaluation will be performed annually. Auditory testing will be performed annually for participants with measurable hearing. Participants with initially untreated vestibular schwannomas will be followed annually with vestibular testing. Speech and swallowing reassessments will be repeated if worsening of speech or swallowing is reported. Blood will be collected at each visit for blood biomarker testing Outcome measures We hope to understand the biologic basis for speech and swallowing dysfunction in patients with NF2. We will study and report the strength of association of MRI findings, clinical assessments cranial nerve deficits and speech/swallowing dysfunction. We hope to identify imaging biomarkers of hearing loss in NF2. We will attempt to discover the mode of peripheral neuropathy in patients with NF2. Lastly, we will attempt to discover previously unknown serum biomarkers associated with high tumor burden in NF2. ...
In this research study the investigators want to learn more about an alternate, local treatment for skin schwannomas. Specifically, local doxycycline intra-tumoral injection will be performed as a potential treatment for NF2-related skin schwannomas, ultimately reducing the risks and costs associated with standard surgical removal of such skin tumors if successful.
This is a multi-arm phase II platform-basket screening study designed to test multiple experimental therapies simultaneously in patients with NF2-related schwannomatosis (NF2-SWN, formerly known as neurofibromatosis type 2) with associated progressive tumors of vestibular schwannomas (VS), non-vestibular schwannomas (non-VS), meningiomas, and ependymomas. This Master Study is being conducted as a "basket" study that may allow people with multiple tumor types associated with NF2-SWN to receive new drugs throughout this study. Embedded within the Master Study are individual drug substudies. * Investigational Drug Sub-study A: Brigatinib * Investigational Drug Sub-study B: Neratinib
Patients with clinically confirmed neurofibromatosis type 1 (NF1) or neurofibromatosis type 2 (NF2) or a known neurofibromatosis (NF) mutation aged 5 years and above will be eligible to participate and will be recruited from the neurofibromatosis clinic. Given the need for identifying measures that can reliably and sensitively measure focal muscle weakness and allow for measuring muscle strength as a functional outcome in therapeutic clinical trials in NF, this pilot study will assess the reliability of measuring muscle strength in NF1 and NF2 using a hand-held dynamometer.
The Nucleus 24 Auditory Brainstem Implant (ABI) is the only FDA approved device for restoration of meaningful hearing in Neurofibromatosis Type 2 (NF2) patients. This device has been discontinued, meaning that there is no commercially approved device currently available. The replacement model, the ABI541 (an unapproved device), is being investigated in ongoing clinical trials. A compassionate use arm of a clinical trial allows patients with NF2 to be implanted with this new ABI.
The primary objective is to estimate the proportions of vestibular schwannomas (VS) and meningiomas after 10 days of exposure to the study drug RAD001 at a dose of 10 mg daily, as determined by immunohistochemistry. This is a "phase 0" PK (pharmacokinetic) and PD (pharmacodynamic) study of RAD001 in patients with Neurofibromatosis Type 2-related and sporadic VS and meningiomas. Enrolled patients will take RAD001 prior to a scheduled VS or meningioma surgery, and blood and tissue samples will be obtained for further analysis.
To determine the hearing response rate at 24 weeks after treatment with bevacizumab for symptomatic vestibular schwannomas (VS) in children and young adults with Neurofibromatosis Type 2 (NF 2).
The purpose of the study is to determine if RAD001 treatment will shrink or slow the growth of the vestibular schwannoma(s) in Neurofibromatosis 2 (NF2) patients. Secondary objectives include determining if RAD001 treatment will improve hearing ability in NF2 patients. RAD001 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.
This will be a multi-center, proof of concept phase 0 study to assess the suppression of p-AKT in Vestibular Schwannoma (VS) and meningiomas by AR-42 in adult patients undergoing tumor resection. AR-42 is a small molecule which crosses the blood brain barrier (BBB) in rodents, but the investigators are not certain yet if it will penetrate human VS. Meningiomas are outside the BBB, but seem to be unusually resistant to all current medical treatments. The primary endpoint of the bioactivity of suppression of p-AKT by AR-42 was selected as drug activity seems more informative than bioavailability. Our preclinical data and others have shown dose dependent suppression of p-AKT by AR-42 in both VS and meningiomas.
This phase I trial studies the side effects and best dose of bevacizumab and temsirolimus alone or in combination with valproic acid or cetuximab in treating patients with a malignancy that has spread to other places in the body or other disease that is not cancerous. Immunotherapy with bevacizumab and cetuximab, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as valproic acid, 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. It is not yet known whether bevacizumab and temsirolimus work better when given alone or with valproic acid or cetuximab in treating patients with a malignancy or other disease that is not cancerous.
