Filter by:The primary objective of this study is to determine whether the administration of tanezumab, an anti-nerve growth factor (NGF) antibody, improves pain relief in schwannomatosis patients receiving background non-NSAID therapy.
This study evaluates mirdametinib (PD-0325901) in the treatment of symptomatic inoperable neurofibromatosis type-1 (NF1)-associated plexiform neurofibromas (PNs). All participants will receive mirdametinib (PD-0325901). Eligible participants may continue in a long-term follow-up phase.
This study is being conducted to determine if Whole Body MRI (WBMRI) can be used to identify Atypical Neurofibromas (ANF) in Neurofibromatosis Type 1 (NF1) patients with high tumor burden. Each enrolled participant will have two (2) WBMRIs without sedation during the study period. Eligible participants must be Male or Female between the ages of 8-30 with diagnosed NF1; with one or more PN greater than 3cm in diameter and willing to comply with study procedures.
This trial, Treatment of NF1-related plexiform neurofibroma with trametinib; a single arm,open-label study with the goals of volumetric partial remission and pain relief (EudraCT 2018-001846-32, Sponsor protocol number BUS2018-1, related Novartis reference number CTMT212ASE01T) is a pediatric clinical trial that investigates the potential use of the drug trametinib (Mekinist®) as treatment for symptomatic or likely to become symptomatic NF1-related plexiform neurofibromas (PN) in children between 1 year and 17 year and 11 months of age. Trametinib is orally administered qd at 0.025 mg/kg up to a maximum of 2 mg from six years of age and 0.032mg/kilo up to 5 years of age, provided either as tablets or as oral solution. It is manufactured and distributed by Novartis under the trade name Mekinist®. The primary endpoint is remission of tumor volume ≥20%, evaluated using volumetric MRI at 18 and 30 months of treatment. The secondary endpoint is reversal of pain from NF1-related PN, evaluated monthly with agespecific pain scales; VAS scale (from 8 years) or Faces Pain Scale (from 3 to 8 years). As an exploratory measure, the potential effects of the treatment on the cognitive function will be assessed using well-established tests such as WISC-V (age range 6:0 - 16:11), NEPSY-II (age range 3:0-16:11), and CPT-3 (age range 8:0 - adult). Cognitive dysfunction is well described in patients with NF1, and the MAPK/ERK-pathway has been indicated to be involved in cognition.
This is a phase 2, open-label, interventional clinical trial that will study the response rate of pediatric glioma and plexiform neurofibroma (PN) to oral administration of trametinib. Patients meeting all inclusion criteria for a given study group will receive the study medication at a daily dose of 0.025 mg/kg up to a total of 18 cycles, in 28-day cycles. A total of 150 patients will be recruited as part of this clinical study. Patients aged between 1 month (corrected age) and 25 years old will be eligible, in order to include a maximum of patients affected by low-grade glioma (LGG) and PN. This study includes four groups: patients with neurofibromatosis type 1 (NF1) and LGG, NF1 patients with PN, patients with LGG with a B-Raf Serine/Threonine-protein Kinase/Proto-oncogene Encoding B-Raf (BRAF) fusion and patients with glioma of any grade with activation of the Mitogen-activated Protein Kinase/Extracellular Signal-regulated Kinases (MAPK/ERK) pathway. All patients except patients with PN must have failed at least one line of treatment. The study will also explore the molecular mechanisms behind tumor development, progression and resistance to treatment. Furthermore, this study will also explore important aspects for patients with brain tumors by including assessment of quality of life and neuropsychological evaluation.
This is a phase II open label study that will evaluate children ≥ 1 year of age and adults with neurofibromatosis type 1 (NF1) and plexiform neurofibromas treated with the MEK inhibitor, binimetinib. The primary objective is to determine if there is an adequate level of disease responsiveness to binimetinib in children and adults with NF1 and inoperable plexiform neurofibromas. The objective response to binimetinib is defined as ≥ 20% decrease in tumor volume reduction by 12 courses.
This phase II trial studies how well trametinib works in treating patients with juvenile myelomonocytic leukemia that has come back (relapsed) or does not respond to treatment (refractory). Trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
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.
Background: Neurofibromatosis type 1 (NF1) is a disorder that can cause plexiform neurofibromas (PNs). These are tumors that grow along nerves. Some PNs cause serious health problems. PNs often can t be operated on because of their large size, location, or number. There are no effective treatments known for people with NF1 and PNs. Researchers want to test if the drug selumetinib (AZD6244 hydrogen sulfate) causes PNs to shrink or slows down their growth. Objectives: To test if selumetinib helps treat PNs. To test how the body handles selumetinib and how it affects peoples symptoms. Eligibility: People ages 18 and older with NF1, with an inoperable PN that causes morbidity or is growing Design: Participants will be screened with: Medical history and physical exam Blood, urine, and heart tests Eye exam MRI: They lie in a machine that takes pictures of the body. PN biopsy: A small piece of the tumor is removed by a large needle. Questionnaires Participants will swallow selumetinib capsules every 12 hours for several 28-day cycles. The capsules are taken with a full glass of water on an empty stomach. Participants may have only water for 2 hours before and 1 hour after each dose. Participants will keep a drug diary. They will continue taking the drug as long as they tolerate it and their disease doesn t progress. Participants will have several visits throughout the study. These will include repeats of the screening tests. Participants will have a final visit after they stop taking selumetinib.
Thanks to the investigators previous study the investigators demonstrated the influence of modifying genes in the phenotypic expression of neurofibromatosis 1 (Hum Mol Genet. 2009; 18 (15) :2768-78). Indeed, analysis of the intra-and inter-family variability performed using the investigators phenotype/genotype database demonstrated a strong genetic component for most clinical features. The investigators results suggest the involvement of genetic factors, not related to the NF1 gene, the modifiers. The objective of this project is to identify the modifiers involved in the variability of clinical expression of NF1. The investigators will focus in particular variants involved in the development and progression of neurofibromas.
