Bevacizumab in Treating Patients With Recurrent or Progressive Meningiomas
Acoustic SchwannomaAdult Anaplastic Meningioma8 moreRATIONALE: Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. PURPOSE: This phase II trial is studying how well bevacizumab works in treating patients with recurrent or progression meningiomas.
Topical Imiquimod 5% Cream for Treatment of Cutaneous Neurofibromas in Adults With Neurofibromatosis...
Neurofibromatosis Type 1Cutaneous NeurofibromasThe 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.
Medical Treatment of "High-Risk" Neurofibromas
Neurofibromatosis 1Patients with neurofibromatosis type 1 (NF1) commonly develop non-cancerous tumors called plexiform neurofibromas. These tumors can be defined as "high-risk" when they result in severe pain, physical disability, organ dysfunction and/or become life-threatening. Presently, there is no effective medical therapy to offer patients with "high-risk" plexiform neurofibromas, and surgery does not provide lasting help. This study will evaluate the effectiveness of two treatment combinations in patients with "high-risk" plexiform neurofibromas.
A Phase II Study of the mTOR Inhibitor Sirolimus in Neurofibromatosis Type 1 Related Plexiform Neurofibromas...
Neurofibromatosis Type 1Treatment Overview This phase II study will evaluate the activity of sirolimus in children and adults with NF1 and inoperable plexiform neurofibromas that have the potential to cause significant morbidity. The following disease strata will be studied: Stratum 1: Progressive plexiform neurofibroma(s) that have the potential to cause significant morbidity. The endpoint will be time to tumor progression based on volumetric tumor measurements. Stratum 2: Plexiform neurofibromas without documented radiographic progression at trial entry. The endpoint will be radiographic response. As of May 2009, Stratum 2 was closed to enrollment. Stratum 1 is active.
A Study to Evaluate Bioavailability and Food Effect of Selumetinib (AZD6244) in Healthy Male Participants...
Neurofibromatosis Type 1 (NF1)-Related Plexiform Neurofibromas (PNs)Healthy ParticipantsThis study will evaluate bioavailability and food effect of selumetinib (AZD6244) in healthy male participants. A total of 24 healthy male participants will be included to ensure at least 20 evaluable participants. The study is divided in 2 study parts; the same participants will participate in both parts of the study. Part 1 of the study is to investigate the pharmacokinetics (PK) of the selumetinib granule compared to the PK of selumetinib capsule, when administered with water under the fasted conditions. Part 2 of the study is to investigate the PK of selumetinib granule and capsule under fed conditions. Participants will also receive a single 500 mg dose of acetaminophen at the same time as selumetinib administration.
Lapatinib Study for Children and Adults With Neurofibromatosis Type 2 (NF2) and NF2-Related Tumors...
Neurofibromatosis 2Vestibular SchwannomaThe 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.
Study of Tasigna®/Nilotinib (AMN107) in Neurofibromatosis (NF1) Patients With Plexiform Neurofibromas...
NeurofibromatosisNF11 moreThe purpose of this Pilot Study is to determine if NF1 patients with plexiform neurofibromas treated with Tasgina® respond to therapy.
Use of RAD001 as Monotherapy in the Treatment of Neurofibromatosis 1 Related Internal Plexiform...
Neurofibromatosis Type 1Plexiform Neurofibroma1 moreBackground: Patients with the genetic disorder neurofibromatosis Type 1 (NF1) are at increased risk of developing tumors of the central and peripheral nervous system. These include plexiform neurofibromas. The conventional treatment of these internal plexiform neurofibromas is surgery. This surgery can be possible on a single and limited tumor. On the other hand these tumors are often surgically intractable due to their multiplicity and their infiltrating characteristics Increased activity of mammalian target of rapamycin(mTOR) protein is seen in neurofibromas. mTOR inhibitor rapamycin , or its derivatives such as everolimus may slow or stop tumor growth in patients with NF1. Objectives: Primary objectives To determine whether everolimus has an effect on the volume of surgically intractable and life-threatening internal plexiform neurofibromas in patients with neurofibromatosis 1. Secondary objectives To determine whether everolimus has an effect on the number and the volume of cutaneous neurofibromas; to determine whether everolimus modify the signaling pathways in cutaneous neurofibromas. Eligibility: - Adults with neurofibromatosis type 1 with at least one internal plexiform neurofibroma, life-threatening or causing significant morbidity through compression of organs. This or these internal plexiform neurofibroma(s) should be intractable by surgery. Design: An open-label, single arm, non-randomized, single stage phase IIa study. Baseline phase: Baseline evaluations will be performed within 2 weeks, and up to a maximum of 4 weeks for specific exams, before the first dose of study drug. Treatment phase/duration of treatment: All patients will be treated with RAD001 10 mg p.o daily dose for one year except in case of unacceptable toxicity, death, or discontinuation from the study for any other reason. Follow-up phase: All patients will have two follow-up visits scheduled at 18 and 24 months after the first dose of the study drug to follow for adverse events (AEs) and serious adverse events (SAEs) that may have occurred after discontinuation from the study and for internal plexiform neurofibromas assessment. Radiological review: All Magnetic Resonance Imaging (MRIs) obtained at baseline, during the treatment period and the follow-up period will be reviewed by the Neuroradiologist of the study.
Phase II Trial of Sunitinib (SU011248) in Patients With Recurrent or Inoperable Meningioma
CNS CancerMeningioma3 moreThe 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.
A Randomized Placebo-Controlled Study of Lovastatin in Children With Neurofibromatosis Type 1
Neurofibromatosis Type 1The specific aim of this study is to determine whether Lovastatin ™ significantly improves visual spatial learning and/or sustained attention in children with NF1. Secondary Aims: To evaluate the effect of Lovastatin ™ on measures of executive function, behavior and quality of life in children with NF1 and cognitive deficits. To further evaluate the toxicity and tolerability of Lovastatin ™ in children with NF1 and cognitive deficits. Hypotheses It is hypothesized that Lovastatin ™ will improve the visual spatial memory and/or attention deficits in children with NF1. This is based on studies demonstrating that Lovastatin ™ has significantly improved impairments in visual spatial memory and attention in the NF1 murine model. It is further expected that Lovastatin ™ will be safe and well tolerated over a 16-week period.
