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.
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.
The purpose of this study is to find out whether avutometinib is a safe treatment for advanced or recurrent solid tumor cancers in children and young adults. Researchers will look for the highest dose of avutometinib that is safe and cause few or mild side effects.
A study to evaluate the efficacy of FCN-159 in adult patients with symptomatic, inoperable neurofibromatosis type 1-related plexiform neurofibromas.
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.
This is a Multi-center, Open-label, Single-arm Phase II Study to Evaluate the Efficacy and Safety of HL-085 in the treatment of Adult Participants with Neurofibromatosis Type 1 (NF1) and Inoperable Plexiform Neurofibromas(PN)
Neurofibromatosis type 1 (NF1) is an autosomal dominant disease affecting chromosome 17. It is manifested by a neurogenic tumor proliferation that forms cutaneous, subcutaneous or deep neurofibromas. Neurofibromas can cause functional discomfort, neurogenic pain that is difficult to treat, and severe cosmetic disorders. Treatment is essentially surgical. It is sometimes a heavy invasive surgery with complicated postoperative follow-up and significant scarring on the aesthetic level. Currently, no systemic treatment has proven its effectiveness in this pathology. Percutaneous cryotherapy is a cold thermoablation procedure using fine 17 G needles introduced into the lesion after targeting by imaging. This technique is used in the treatment of soft tissue tumors and desmoid tumors. The treatment of neurofibromas with percutaneous cryotherapy is not well known. Encouraging results (unpublished) have been observed in patients with NF1 treated with cryotherapy at the Léon Bérard Center. The beneficial effect was observed in terms of quality of life (in particular, pain) as well as a decrease in tumor size. On the basis of this first experience, it appears important to corroborate these preliminary results by a prospective study allowing the use of this technique to treat patients with unresectable or resectable neurofibromas but with mutilating surgery in a NF1 context.
The purpose of the research study is intended to use specimens (such as tissue) and medical information in the Laboratory of Musculoskeletal Oncology at the Van Andel Research Institute for laboratory research in Grand Rapids, Michigan. Small tissue samples of cutaneous neurofibromas will be collected as part of this research. The samples will help researchers learn more about cutaneous neurofibroma and help them better understand NF1. There are many different types of studies, both now and in the future, that can be done using the specimens the investigators receive. These include using the specimens and information to look for new ways to diagnose and treat Neurofibromatosis Type 1 (NF1). The specimens may be used to study how genes affect health and disease, or how genes affect the way a disease or condition responds to treatment. Some of these studies may lead to new products, such as treatments or tests for diseases. Through this study, the investigators hope to find better ways to understand and treat NF1 in the future.
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.
Background: People with neurofibromatosis 1 (NF1) who have plexiform neurofibromas (pNFs) can have pain that affects their daily lives. This study aims to improve questionnaires that measure their pain, daily living, and physical functioning. Objectives: To examine and improve questionnaires about daily living for people with NF1 and pNFs. Eligibility: People ages 5 and older with NF1 and a pNF Design: Participants will be screened with medical history. This study will have 2 phases. Phase 1 participants will talk about existing pain assessment questionnaires and how pNFs affect their life. They will have group discussions of up to 8 people of a similar age with NF1 and pNFs, or the parents of children with it. These will last about 90 minutes. Children ages 5 to 7 and their parents will have one-on-one meetings instead. These will last about 45 minutes. Discussions will be audiotaped. After the questionnaires have been changed, individual interviews will discuss the new wording, instructions, questions, and electronic format of the new forms. Phase 2 is now complete. Phase 1 participants may be invited to Phase 2. Phase 2 participants will complete the new questionnaires. These may be pen-and-paper or electronic. The questionnaires will take about 30 minutes for adults and teens. Children will work one-on-one with a staff member and may need up to 45 minutes. A small group of participants will be complete the forms twice-in clinic and 1 month later at home. Also, a small group who start a new pain treatment or have a dose increase in their treatment will complete the forms twice-before the treatment change and 1 month later.
