Filter by:The goal of this observational study is to conduct a prospective assessment of the individual Burden of 9 rare skin diseases to assess disability in the broadest sense of the term (psychological, social, economic and physical) for patients and/or families. Two types of indicators will be used to reach this objective : 1. an individual burden score calculated based on a burden questionnaire created specifically, approved and designed to understand the tendency to changes in care and lifestyles. The burden questionnaire should be used by patients and/or their family themselves in self-assessment. 2. a descriptive analysis of all resources (medical and non-medical) used by the family unit to manage the disease.
This is a phase II, multicenter, randomised, parallel, double-blind, placebo-controlled study assessing the efficacy and safety of the MEKi selumetinib compared with placebo in Chinese paediatric participants with post-operative NF1-associated PNs.
The purpose of this study is to understand treatment patterns and assess long-term effectiveness and safety outcomes associated with selumetinib treatment as well as to explore clinical and non-clinical factors affecting those outcomes in participants with neurofibromatosis type 1 (NF1) and plexiform neurofibromas (PNs) who were aged 2 to 18 years at the time selumetinib was started in a real-world setting.
People diagnosed with NF1 may develop cutaneous neurofibromas, also known as cNFs. These benign tumors can cause discomfort and affect a person's quality of life. Researchers at Johns Hopkins are studying how cNF tumors form, grow and change over time. This information may help doctors in the future, provide early interventions and improve quality of life for NF1 patients. Researchers will also explore a new way of monitoring cNF with 3D camera technology. People of all ages with NF1, living in the United States, are invited to participate in this important research study.
Neurofibromatosis type 1 (NF1) is a rare, autosomal dominant genetic disorder that is caused by germline mutations in the NF1 tumour suppressor gene, which encodes the tumour suppressor protein neurofibromin 1. Plexiform neurofibromas (PN) are histologically benign nerve sheath tumours, which typically grow along large nerves and plexi. On 5 March 2020, a centralised Marketing Authorisation Application was submitted to the European Medicines Agency (EMA), Marketing Authorisation in EU was granted on 17 Jun 2021. As part of the approval process, a Risk Management Plan (RMP) was developed and submitted to the EMA to summarise the safety concerns emerging from the clinical development program. The RMP included additional pharmacovigilance plans for a noninterventional Post-authorisation Safety Study (PASS) to further characterise the safety of selumetinib in paediatric patients with NF1-related PN in routine clinical practice. The planned non-interventional PASS will address gaps in knowledge identified by the RMP, including the important identified risk and some of the potential risks and missing information on long-term developmental toxicity in children, by characterising the safety profile associated with selumetinib use among paediatric patients (age d 8 to < 18 years old) with a diagnosis of NF1 with symptomatic, inoperable PN. This study is a specific obligation in the context of a conditional marketing authorisation for selumetinib (ie, Category 2 PASS). Study results will contribute to updating the safety profile of selumetinib in a relatively large population of patients with different personal characteristics across multiple health care systems and patterns of real-world clinical practice in European countries and Israel. The study will enrol 2 cohorts: 1. The Base Cohort includes all enrolled patients aged 3 to < 18 years. 2. The Nested Prospective Cohort will include the subset of Base Cohort patients aged 8 to < 18 years who have not reached Tanner Stage V on the index date.
This study is designed to define a dosing regimen and assess the pharmacokinetics(PK) and safety of the granule formulation; the study will also include descriptive analyses of exploratory efficacy endpoints. The study will inform the benefit risk profile of the granule formulation in children aged ≥ 1 to < 7 years with NF1 related symptomatic, inoperable PN.
The purpose of this study is to identify tumor biomarkers in individuals with Neurofibromatosis type 1 (NF1). Biomarkers are signals that the investigator can measure that tell us about a process such as progress of a disease or treatment. Individuals with this diagnosis are at an elevated risk of developing a type of tumor called a plexiform neurofibroma. Currently, detecting the risk factors of these tumors in children is difficult and requires whole body imaging. The NF1 team at Lurie Children's established a way of using blood plasma in mice with neurofibromatosis type 1 to identify biomarkers that might signal the presence of tumors in people with NF1. This study is an effort to create biomarker profiles of patients with NF1 with known tumors. The study team will utilize whole-body MRI and mass spectrometry (a method for identifying unknown compounds and the properties of molecules). The ultimate goal of this study is to better understand the tumor biomarkers in patients with NF1.
To examine the test-retest reliability (how stable the results are when the same participants, whose symptoms have remained stable, are assessed on 2 different occasions, 14 days apart) of the 10 meter walk test, the timed up and go test, the functional reach test and the grip dynamometry test in adults with neurofibromatosis 1 (NF1).
Neurofibromatosis 1 (NF1) is a multisystem disorders characterized by skin abnormalities, such as café-au-lait spots and neurofibromas, learning disabilities, skeletal anomalies and vascular complications. Experience learns that this disorder is a great burden for patients. NF1 is an autosomal dominant disorder with 50% risk of transmission. The penetrance is nearly 100%, but the expression varies greatly even within families, which makes it nearly impossible to predict severity in offspring. Preimplantation genetic diagnosis (PGD) is a reproductive option for couples at risk of transmitting NF1 to their offspring. We perform a retrospective and observational multicentric study in the Maastricht University Medical Center, the University Hospital of Brussel and Strasbourg University Hospital. Our specific (and first) goal is to evaluate the molecular aspects of PGD for NF1 in an international cohort of couples requesting PGD for NF1. About 50% of the patients with NF1 have a de novo mutation that can complicate development of a PGD test. Earlier studies from 1990 and 1992 have shown that de novo NF1 mutations usually occur on the paternal allele. We want to confirm these findings with collected data from our cohort. The high incidence of de novo mutations results in a higher chance of finding mosaicism in patients or their parents. As a result of this, it can become apparent during PGD test preparation that PGD treatment is no longer possible or indicated. The investigators will evaluate these aspects of PGD for NF1 in our cohort. They are also interested, as a second goal, in other aspects of PGD treatment for NF1, such as the success rate in thier cohort. They expect the success rate to be the same as for other autosomal dominant disorders
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.
