Filter by:This is a phase I open label study designed to evaluate the safety, tolerability, PK and efficacy of selumetinib in Japanese paediatric patients with neurofibromatosis type 1 and inoperable and symptomatic plexiform neurofibroma.
The objective of this study is to determine if children and young adults with Neurofibromatosis Type 1 (NF1) and either Low Grade Gliomas (LGGs) or Plexiform Neurofibromas (PNs) have a specific frameshift peptide protein profile and whether a disease specific vaccine created to address these frameshift mutations and variants can be developed. Three study populations will be analyzed; patients with NF1 and active LGGs, NF1 and active PNs, and NF1 and no evidence of active LGGs or PNs. Participation involves a onetime blood draw.
The objective of this study is to study the function of the pigment epithelium in patients with neurofibromatosis type 1 using electro-oculogram to confirm abnormally high values reported in previous studies, but also to correlate this hyperactivity of the pigment epithelium with the presence and size of choroidal hyperreflective areas observed in infra-red imaging of the fundus. The hypothesis of the study is that the function of the pigment epithelium measured by the electro-oculogram correlates with the surface of choroidal hyperreflective areas. Finally, the potential consequences of a supra-normal function of the pigment epithelium on the global retinal function are not known. A full-field electroretinogram will evaluate the global neurosensory retinal function.
It is known that children with NF1 can have weak muscles and suffer from tiredness. It is also known that in similar conditions affecting children's muscles, standing on a vibration device for a few minutes each day can strengthen muscles and improve their ability to perform day-to-day activities. The investigators believe this vibrating platform can be used to strengthen the muscles of children with NF1 also, beyond standard exercises, and therefore allow them to perform day-to-day activities better, do more activity and feel less tired. If families are keen to take part in this study, the investigators will first need to check they are suitable for the trial. This will be based on the participant's age (6-16 years), their other medical problems that would affect use of the vibration device or tests to assess how effective it is, and their level of muscle weakness. Once families have agreed to take part, participants will be randomised either to receive a muscle-strengthening exercise session delivered by a physiotherapist that children with weak muscles should continue to perform daily for the next 6 months; or to receive a vibration device to take home and use for a few minutes 5 days a week for 6 months as well as the exercises. All participants will be invited to attend for a variety of activities and tests, just before starting the trial and 6 months later at the end of the trial to see if there is any benefit from the vibration device. The investigators will repeat these tests again 3 months later, to see if any benefits observed remain, even after the device is removed. They will involve jumping, hopping and balancing on a board, gripping a machine as hard and as long as possible, being fitted with a device that measures activity for 7 days, walking as far as possible for 6 minutes, scanning muscles using MRI, completing a tiredness and general well-being questionnaires, and parents completing a questionnaire of the participant's attention and intellect. The jumping will also be performed 3 months into the study, to see if there is any early improvement in this key test. All participants will be given full details of what the trial involves before taking part. As with any other trial, participants and their families are free to stop taking part at any time. Although the investigators do not anticipate any safety issues, if any do arise, the families will be asked to contact the trial team.
Phase I and II study of the MEK inhibitor Selumetinib given twice daily on 5 out of 7 days in children with NF1 and inoperable plexiform neurofibromas or progressive/relapsed optic pathway gliomas. This study will test the early and late toxicities of selumetinib when it is given in this intermittent schedule (in 5 out of 7 days) and will also test the effectiveness of the drug in reducing the size of plexiform neurofibromas and optic pathway gliomas in children with NF1. It will also test the effectiveness of the drug in improving the participants function in day to day life.
The main objective of the study is to assess the efficacy of a home-based, computerized cognitive training (CT) program, called CogmedRM, targeted to improve working memory in children with NF1 and working memory difficulties. This is a Phase II randomized parallel group controlled clinical trial comparing two interventions on cognitive outcomes. Participants will be stratified by stimulant medication use and randomized equally between the two interventions within stratum. Participants will be in the study for to 11 weeks.
This pilot phase II trial studies how well selumetinib works in treating patients with neurofibromatosis type 1 and cutaneous neurofibromas. Selumetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
Background: - People with neurofibromatosis type I (NF1) and plexiform neurofibroma (PN) tumors often have chronic pain that his hard to control. People usually take medicines for the pain, but they may not work well and might cause side effects. A new strategy called Acceptance and Commitment Training (ACT) may help these people cope with chronic pain. ACT focuses on things like values and living in the moment. Objective: - To see if Acceptance and Commitment Training improves pain coping in people with NF1 pain. Eligibility: - People age 16-34 who have NF1, 1 or more PN tumors, and pain that interferes with their daily functioning. Design: - Participants will be screened with a physical exam, medical history, and questions about their pain. - Participants will fill out questionnaires about their pain and feelings. Their heart rate will be measured via electrocardiogram (ECG). - Participants will be divided into 2 groups randomly. One will wait 8 weeks. - The other will start training right away. - Participants will have 2 two-hour sessions with an ACT trainer. They will learn techniques for setting goals based on personal values and other ways to cope with pain. They will get a workbook and a compact disc (CD) to take home for practice. - Participants will do practice exercises at home between sessions. They will get weekly emails with a practice exercise. They will join video chat sessions via home computer with their trainer. - All participants will return to National Institutes of Health (NIH) after 8 weeks for questionnaires and an ECG. The wait group will then start training. They will return 8 weeks later for questionnaires and an ECG. - Six months later, they will complete questionnaires from home by computer.
A monocenter pilot study on the acceptability and feasibility of a functional MRI protocol in children with NF1 with or without reading disabilities.
This phase I trial studies the side effects and best dose of pomalidomide in treating younger patients with tumors of the brain or spine (central nervous system) that have come back or are continuing to grow. Pomalidomide may interfere with the ability of tumor cells to grow and spread and may also stimulate the immune system to kill tumor cells.
