Filter by:This study is a Phase I clinical trial to evaluate the tolerability and pharmacokinetics of TQ-B3234 capsules in Chinese subjects associated with neurofibromatosis type I (neurofibroma and peripheral malignant neurilemmoma). Two study phases were designed, including (1) dose escalation and (2) cohort expansion. The purpose of this study was to evaluate the tolerance, pharmacokinetic characteristics, efficacy and safety of TQ-B3234 capsule, and to explore the therapeutic biomarkers related to this product.
This study in adolescent participants with NF1 who have inoperable PN is designed to evaluate the effect of a low fat meal on steady state selumetinib exposure; to assess the effect on GI tolerability when selumetinib is dosed under fed and fasted conditions; and potentially, to confirm an appropriate dosing recommendation of selumetinib with a low fat meal that maintains efficacy with acceptable safety. These results may support labelling statements with regard to posology and food.
This program is being offered on a patient by patient basis and will require company, Institutional Review Board/Independent Ethics Committee, and applicable competent authority approval.
AL2846 is a multi-target receptor tyrosine kinase inhibitor. The purpose of this study is to evaluate the safety and efficacy of AL2846 capsules in Chinese patients with type I neurofibromatosis (NF1) (neurofibromas and malignant peripheral nerve sheath tumors).
This is a randomized, double-blind, vehicle-controlled, parallel group dose response study evaluating the safety and effectiveness of 2 concentrations of NFX-179 Gel in subjects with cutaneous neurofibromas. At Visit 1, the investigator will identify 10 Target cNFs that fulfil the enrollment criteria. The Target cNFs must be located on the subject's face, anterior trunk, or upper extremities. Two Target cNFs must be on the face and 8 must be on the anterior trunk or upper extremities. The study medication will be applied topically QD to the Target cNFs for 182days (26 weeks). During the duration of the study subjects will be evaluated for safety and efficacy.
Intellectual impairment, particularly working memory deficits are a significant cause of morbidity in children with Neurofibromatosis type (NF1) with long-term implications on academic and occupational functioning. Whilst significant discoveries have been made in Nf1 animal models in trying to find treatments for these conditions, human translational studies have not been successful. This mechanistic experimental study will investigate the neural mechanisms underlying working memory deficits in NF1. In particular, we will investigate how individual differences in inhibitory neurotransmitter GABA relate to performance on working memory tests. Further, we will investigate the use of a novel, experimental intervention called transcranial Direct Current Stimulation (tDCS);known to modulate GABA. Using a randomized, crossover design in a cohort of 30 adolescents aged 11-17 years, we will apply real or sham tDCS to the dorsolateral prefrontal cortex (DLPFC). State-of-art real time imaging techniques such as Magnetic Resonance Spectroscopy (MRS) and task based functional MRI (fMRI) will be used to investigate the effect of tDCS on GABA concentration, changes in functional plasticity and working memory. We expect that results from this study will help elucidate the neural mechanisms underlying working memory deficits in people with NF1 and show biologic activity for a novel, low-cost intervention that can be used for cognitive remediation in NF1. This kind of focused mechanism trial method is a highly promising approach to understanding the complex neural system pathology in a multifactorial neurodevelopmental condition like NF1.
FCN-159 is a highly active MEK1/2 inhibitor that was designed, synthesized and screened on the basis of the structure of trametinib. FCN-159 is an orally available and highly potent selective inhibitor of MEK1/2, which is expected to be a targeted therapy for the treatment of advanced solid tumors and neurofibromatosis type 1.
The main goal of this protocol is to develop a well-phenotyped genetic biobank to identify genetic variants associated with the heterogeneous clinical presentations of Neurofibromatosis Type 1 (NF1). This will allow for improve understanding of NF1 pathogenesis and more personalized disease management. The investigators will conduct a GWAS analysis to identify common genetic risk variants associated with the development of cutaneous neurofibromas.
A global study to demonstrate the effectiveness of selumetinib in participants with NF1 who have symptomatic, inoperable plexiform neurofibromas.
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.
