Active clinical trials for "Neurofibromatosis 1"

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.

This study is being conducted to determine if Whole Body MRI (WBMRI) can be used to identify Atypical Neurofibromas (ANF) in Neurofibromatosis Type 1 (NF1) patients with high tumor burden. Each enrolled participant will have two (2) WBMRIs without sedation during the study period. Eligible participants must be Male or Female between the ages of 8-30 with diagnosed NF1; with one or more PN greater than 3cm in diameter and willing to comply with study procedures.

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 Encouraging results (unpublished) have been observed in patients with NF1 treated with cryotherapy at the Léon Bérard Center.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 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 clinical trial will test the safety and efficacy of combining trametinib and azacitidine in patients with juvenile myelomonocytic leukemia (JMML). Newly diagnosed lower-risk JMML patients will receive trametinib and azacitidine. High-risk JMML patients will receive trametinib, azacitidine, fludarabine, and cytarabine.

Subjects with Neurofibromatosis Type 2 (NF2) and progressive vestibular schwannoma (VS) will be treated with crizotinib administered orally. Crizotinib will be taken continuously until disease progression or unacceptable toxicity, in continuous treatment cycles of 28 days each, for a maximum of 12 cycles.

Background: People with chronic illness often are at risk for developing neurobehavioral problems due to effects of the disease or associated treatments. These problems may include cognitive impairments involving problem-solving, remembering things, paying attention, and understanding and using language, or emotional functioning or quality of life. The National Cancer Institute Medical Illness Counseling Center Neuropsychology Group has collected data from neurobehavioral evaluations of infants, children, adolescents and adults with chronic illnesses enrolled in NIH protocols since 1987 and continues to collect data from patients enrolled in current protocols. The data from these evaluations, along with demographic and medical information are stored in an NIH computer database. Investigating the neurobehavioral functioning of patients with chronic illness is important for identifying and monitoring the effects of the disease and treatments over time, determining possible at-risk subgroups, evaluating response to therapy, and recommending educational and rehabilitative interventions. Objectives: -To learn about how certain illnesses or treatments may affect a person s cognitive abilities, emotional functioning and quality of life. Eligibility: Patients currently enrolled in NIH studies who are having neuropsychological testing or completing quality-of-life questionnaires as part of that study. Data obtained from infants, children, adolescents, and adults administered neurobehavioral assessments as part of a past or future NIH protocol. Design: This study does not involve any extra tests or questionnaires; it uses information collected from evaluations that subjects have already completed or will complete as part of other NIH studies. Information about participating patients that may help elucidate how cognitive abilities, emotional functioning, and quality of life are affected in people with chronic illness may be collected and stored.

The goal of this prospective observational study is to learn about the utility of imaging and clinical features in patients with Neurofibromatosis type 1 categorized as high risk for the development of malignant peripheral nerve sheath tumors. The main objectives are: To evaluate the prevalence, multi-parametric imaging features of distinct nodular lesions ("DNLs") and natural history in people with NF1 with clinical and genetic features deemed "high-risk" for malignancy. To assess the relationship between individual clinical, genetic and imaging factors that have been suggested to be risk factors for malignant peripheral nerve sheath tumors (MPNST) and the confirmation of atypical neurofibromas (aNF)/ atypical neurofibromatous neoplasm of unknown biologic potential (ANNUBP) or MPNST on pathology. In this research study, the participants will be asked to undergo whole body MRI, provide blood sample and clinical evaluation annually.

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.

The RASopathies are a group of developmental disorders caused by genetic changes in the genes that compose the Ras/mitogen activated protein kinase (MAPK) pathway. New RASopathies are being diagnosed frequently. This pathway is essential in the regulation of the cell cycle and the determination of cell function. Thus, appropriate function of this pathway is critical to normal development. Each syndrome in this group of disorders has unique phenotypic features, but there are many overlapping features including facial features, heart defects, cutaneous abnormalities, cognitive delays, and a predisposition to malignancies. This research study proposes to collect and store human bio-specimens from patients with suspected or diagnosed RASopathies. Once obtained, blood and/or tissue samples will be processed for: metabolic function studies, biomarkers, genetic studies, and/or the establishment of immortalized cell lines. In addition, data from the medical record (including neuropsychological evaluations) and surveys will be stored to create a longitudinal database for research conducted at CCHMC or at other research institutions.
