Filter by:Background/Rationale: Neurofibromatosis type 1 (NF1) affects about 1 in every 3000 people worldwide. Globally, 30~50% NF1 patients will develop plexiform neurofibromas (PNs), which grow rapidly in early childhood and can cause disfigurement, motor dysfunction, pain, airway dysfunction, visual impairment and bladder and bowel dysfunction. This systemic disease imposes a heavy psychosomatic and financial burden on patients and their caregivers. In NF1 patients, the lifetime risk of MPNST developed from PN is 8% to 13%. The mean age for NF1-associated death was approximately 20 years lower than that for the general population. Limited epidemiological and clinical data of Chinese NF1 patients is available to date. And the treatment pattern of Chinese NF1-PN patients is also unknown. Objectives and Hypotheses: It is a descriptive study without formal hypothesis. The primary objective of this study is determining the percentage of NF1 patients who develop PN. The secondary objectives of this study include describing the clinical characteristics, tumor progression and treatment pattern of NF1-PN. The exploratory objective is exploring the epidemiological characteristics of other NF1 manifestations. Methods: Study design: The study is a retrospective multi-center chart review study. Data Source(s): All the data will be collected by CRF from inpatient and outpatient electronic medical records in every study site from January 1, 2019 to December 31, 2022. Study Population: Patients who attended the study sites between January 1, 2019 - December 31, 2022 and were diagnosed with NF1 were included in this study. Statistical Analysis: This study is purely descriptive without any formal hypotheses. Missing data for baseline characteristics will be assessed and addressed as a categorical variable with a level for missingness. All reported measures will be summarized in the study tables. Point estimates and their 95% CIs will be presented in the final analyses.
As part of a post-approval commitment, the Korean health authority requests a study to characterize safety and effectiveness in patients treated with Koselugo (Selumetinib), an oral selective inhibitor of MAPK kinase (MEK) 1 and 2, by physicians in routine clinical practice settings. This study is designed to assess the known safety profile or identify previously unsuspected adverse reactions and evaluate the effectiveness of Koselugo under conditions of routine daily medical practice in Korea. This study will provide information on the Korean patient population that is treated with the study drug.
This study will evaluate the tolerability and effectiveness of four FDA-approved treatments in Neurofibromatosis Type 1 Cutaneous Neurofibromas. These treatments are: a 1064nm laser, a 755nm laser, and Kybella and Polidocanol injections. Each patient will have a treatment and a control site. This study is designed with the goal of improved efficacy/tumor reduction via multiple treatment visits. If there is minimal to no clinical improvement in tumor size with one treatment after three treatment visits, the subject will be given the option of crossover treatment with the most effective of the four treatments. Three treatment visits with the crossover treatment will then take place.
The goal of this fully decentralized, randomized controlled trial is to compare the efficacy of two educational interventions for individuals with Neurofibromatosis 1 (NF1). The primary objective of the study is to determine which intervention leads to higher rates of evidenced-based health screenings for NF1 patients in primary care settings. Adults with NF1 and parents/guardians of children with NF1 from across the U.S. who do not go to a specialized NF clinic and who have an upcoming annual wellness visits scheduled with a primary care provider (PCP) are eligible to enroll in the study.
Background: Neurofibromatosis type 1 (NF1) is a genetic disease that can cause many symptoms. About half of people with NF1 will develop benign (noncancerous) tumors along nerves in the skin, brain, and other parts of the body. Sometimes, though, these tumors can become cancerous. Researchers do not yet know how to predict which tumors will become cancerous. Objective: To test a new method for predicting which benign NF1 tumors will become cancerous. Eligibility: People aged 3 years and older with a clinical or genetic diagnosis of NF1. Design: - Participants will be screened with a review of their medical history. All participants will have a baseline visit. They will have bood tests and imaging scans. They will have a physical exam. They will answer questions about their family history. Participants aged 8 years and older will take tests of their thinking skills and their emotional health. - Some participants may be asked to undergo more tests. These may include another type of imaging scan and a biopsy: A small sample of tissue may be removed from the tumor. - Participants will be divided into two groups: those believed to be at low risk and those believed to be at high risk of developing cancer. - Participants in the high-risk group will be asked to return for their next visit in 1 month to 3 years. - Participants in the low-risk group will be asked to return for their next visit in 6 months to 5 years. - Participants may also have follow-up visits by phone throughout the study. They will be in the study for 10 years.
Plexiform neurofibromas (PN) are known to cause significant morbidity in children with NF1. The recent FDA approval for selumetinib in children 2 years and older with inoperable symptomatic PN was based on the finding that selumetinib shrinks the majority of PN in children with NF1 and results in clinically meaningful benefit such as improvement in pain or range of motion. However, many morbidities, such as blindness or nerve damage, cannot be fully reversed with PN shrinkage. Therefore, there remains a critical need in this patient population to determine if young participants with PN in high-risk locations may benefit from early medical intervention prior to the development of clinical problems. This study will determine whether participants with asymptomatic PN in high-risk locations can potentially benefit from early treatment with selumetinib.
This is a prospective, multicenter, observational study of Chinese pediatric NF1-PN patients treated with selumetinib. The study will be conducted at approximately 12 centers in China and will include approximately 80-100 patients. Treatment centers that have PN diagnosis and/or selumetinib treatment experience will be targeted for recruitment. Patients/caregivers who are eligible and willing to participate will be enrolled into the study. Patients will start selumetinib treatment after enrollment. The study will have a 16-month enrollment period. Patients will be followed up until the end of a 24-month observation period after first dose of selumetinib, or patient death, lost to follow-up, withdrawal of consent, whichever occurs first. Patients will be followed within a 24-month period (starting after first dose received) in the study even if selumetinib is discontinued. The aims of this study are to expand understanding of disease characteristics and treatment pattern of NF1-PN in China in a real-world setting and to evaluate real-world effectiveness and safety of selumetinib for Chinese pediatric patients with NF1-PN
This is a Phase 1/2a, open-label, non-randomized, multi-dose study of mirdametinib monotherapy in adults with NF1 and cNF. In both Phases of the study, participation in the study will comprise three periods: screening, treatment and post-study safety follow-up to be performed at the NF1 and cNF specialty center: Johns Hopkins University.
Cell-free fetal DNA (cffDNA) is present in the maternal blood from the early first trimester of gestation and makes up 5%-20% of the total circulating cell-free DNA (cfDNA) in maternal plasma. Its presence in maternal plasma has allowed development of noninvasive prenatal diagnosis for single-gene disorders (SGD-NIPD). This can be performed from 9 weeks of amenorrhea and offers an early, safe and accurate definitive diagnosis without the miscarriage risk associated with invasive procedures. One of the major difficulties is distinguishing fetal genotype in the high background of maternal cfDNA, which leads to several technical and analytical challenges. Besides, unlike noninvasive prenatal testing for aneuploidy, NIPD for monogenic diseases represent a smaller market opportunity, and many cases must be provided on a bespoke, patient- or disease-specific basis. As a result, implementation of SGD-NIPD remained sparse, with most testing being delivered in a research setting. The present project aims to take advantage of the unique French collaborative network to make SGD-NIPD possible for theoretically any monogenic disorder and any family.
