Filter by: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).
This was a 4-part (Part A, Part B, Part C and Part D), Phase I/IIa, multi-center, open label, study in pediatric subjects with refractory or recurrent tumors. Part A was a repeat dose, dose escalation and expansion phase that identified the recommended phase II dose (RP2D) of trametinib monotherapy. Part B evaluated the preliminary activity of trametinib monotherapy in 4 disease-specific cohorts of subjects. Part C was aimed to determine the safety, tolerability and preliminary activity of the RP2D of trametinib in combination with a limited dose escalation of dabrafenib. Part D evaluated the preliminary activity of trametinib in combination with dabrafenib in 2 disease-specific cohorts of subjects. The overall goal of this trial was to efficiently establish safe, pharmacologically relevant dose of trametinib monotherapy and trametinib in combination with dabrafenib in infants, children and adolescents and determine preliminary activity of trametinib monotherapy and trametinib in combination with dabrafenib in selected recurrent, refractory or unresectable childhood tumors.
1)Preliminarily evaluate the treatment effect of continuous vein injection of recombinant human endostatin on NF2; 2)Preliminarily evaluate the safety and the patient's tolerance of the treatment of endostatin; 3)Provide an objective basis for an enlarged randomized double-blind trial.
This study, "A Phase II Study of Cabozantinib (XL l84) for Plexiform Neurofibromas in Subjects with Neurofibromatosis Type I in Children and Adults diagnosed with Neurofibromatosis Type 1 (NF1) and have a type of tumor called a plexiform neurofibroma (PN). Neurofibromas are tumors that develop from the cells and tissues that cover the nerves. Plexiform neurofibromas can be disfiguring, painful, and life-threatening. These types of tumors typically do not respond well to most treatment approaches such as chemotherapy, radiation, and surgery because of their slow growth and location near vital structures of the body such as nerves, blood vessels, and the airway. The primary objective is to determine the response rate of NF1 patients with plexiform neurofibromas treated with Cabozantinib therapy using MRI scans. The objective response rate to cabozantinib is defined as ≥ 20% reduction in tumor volume at the end of 12 cycles.
This phase II open label study will evaluate adolescents (≥ 16 years of age) and adults with neurofibromatosis type-1 (NF1) and plexiform neurofibromas treated with the MEK inhibitor PD-0325901. The primary aim of the study will be to assess quantitative radiographic response in a target lesion. Subjects will receive PD-0325901 by mouth on a bid dosing schedule of 2 mg/m2/dose with a maximum dose of 4 mg bid. Each course is 4 weeks duration, and subjects will receive drug on a 3 week on/1 week off schedule. Subjects may receive additional courses beyond course 8 only if there is at least 15% reduction in volume of the target tumor. Subjects who have a 20% or greater reduction in target tumor volume at the end of 12 courses can continue on therapy for up to an additional year (maximum of 24 total courses). However, subjects who do not achieve at least 15% reduction in volume of the target tumor after 8 courses (~8 months) will be considered treatment failures and taken off study. The Primary purpose of this protocol is to determine whether PD-0325901 results in objective radiographic responses based on volumetric MRI measurements in adolescents and adults with NF1 and growing or symptomatic inoperable PN. There are several secondary aims of this protocol: To evaluate the feasibility and toxicity of chronic PD-0325901 administration in this patient population To estimate the objective response rate of up to 2 non-target plexiform neurofibromas to PD-0325901 by MRI To characterize the pharmacokinetic profile of PD-0325901 when administered to this patient population To evaluate quality of life and pain during treatment with PD-0325901
The main objective of the study is to investigate the determinants of the quality of life in children and adults with Neurofibromatosis type 1 (NF1) and more particularly the specific impact of neuropsychological deficits. In fact, cognitive impairment is currently considered as one of the most pervasive features of this genetic disorder but its relationship with the worsening of quality of life found in this population has not been directly investigated to date. Secondary objectives of this study are (i) to compare neuropsychological and quality of life measures between patients and healthy controls matched by age, gender and education level, (ii) to contrast neuropsychological deficits incidence between patients and controls, and (iii) to differentiate NF1 children's self versus hetero-assessment of quality of life. The main hypothesis of this study is that the neuropsychological impairment classically identified in this clinical population will be associated to the quality of life's worsening both in children and adults.
This prospective pilot study is designed to provide preliminary data on the use of Fluorodeoxyglucose Positron Emission Tomography-Magnetic Resonance Imaging (FDG-PET-MRI) in patients with neurofibromatosis-1 (NF1) associated optic glioma and plexiform neurofibroma (PN). Subjects will undergo FDG-PET-MRI scans in place of standard of care imaging at 0 and 12 months, unless more frequent imaging is clinically indicated. Subjects and their family caregivers will also undergo serial interviews and complete questionnaires related to the psychosocial aspects of NF1.
Neurofibromatosis (NF) is a common genetic disorder that cause tumors to grow along various types of nerves and, in addition, can affect the development of bones and skin. It occurs in 1:4000 persons. NF has been classified into three distinct types: NF1, NF2 and Schwannomatosis. NF1 is the focus of this study. NF1 is an extremely variable disorder which ranges from extremely mild cases in which the only signs of the disorder in adulthood may be multiple café-au-lait spots and a few dermal neurofibromas, to more severe cases like disfigurement, scoliosis and learning disabilities. Scoliosis (abnormal curvature of the spine) is perhaps the most common bone deformity in NF1 which usually appears in early childhood. There are two types: dystrophic and non-dystrophic scoliosis. Dystrophic scoliosis is usually associated with other bone deformities which are seen on x-ray and carries a poorer prognosis than non dystrophic scoliosis. There is evidence that genes other than the NF1 gene are responsible for the variable severity of cases. Recent studies have identified genetic markers for another condition called adolescent idiopathic scoliosis (scoliosis which presents in adolescent age group with no known cause). We believe that the same genetic markers may also be present in NF1 patients with scoliosis. Our objective is primarily to determine if the same genetic markers discovered in adolescent idiopathic scoliosis are also present in NF1 patients with scoliosis.

This study will analyze DNA samples to determine associations between maternal and offspring genetic factors and pediatric brain tumor development in children with Neurofibromatosis Type 1. Participating families (mother, father, child) will be asked to complete a short questionnaire and provide DNA samples (either saliva or blood). The information gained from your participation may one day help doctors develop strategies to reduce brain tumor risk in individuals with NF1. Please note: there is no therapy associated with this study.
