Filter by:Bevacizumab can be an effective treatment for individuals with NF2 and improve different nerve functions (like hearing, tinnitus or balance problems) and the quality of life of NF2 patients. However, bevacizumab is not effective in all patients or all tumors, at the cost of moderate toxicity and considerable financial burden. Therefore, this observational study will validate an imaging biomarker method to predict bevacizumab efficacy in order to avoid adverse effects and high costs in non-responders to bevacizumab treatment. Patients will undergo standard-of-care treatment with the sole addition of a pre-treatment 89Zr-Bevacizumab PET/CT-scan. Per standard-of-care bevacizumab therapy is administered every three weeks for six months. To monitor treatment effect, follow-up is performed at 3-month intervals.
This is a placebo-controlled, multi-arm phase II platform screening trial designed to test the safety, pain responses, and pharmacodynamic activity of multiple experimental therapies simultaneously in participants with moderate-to-severe pain due to schwannomatosis (SWN). This Master Study is being conducted as a platform that may allow participants with pain associated with schwannomatosis to receive a novel intervention throughout this study. Embedded within the Master Study are individual drug sub-studies: - Investigational Drug Sub-Study A: Siltuximab - Investigation Drug Sub-Study B: Erenumab-Aooe
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.
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.
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.
In this research study the investigators want to learn more about an alternate, local treatment for skin schwannomas. Specifically, local doxycycline intra-tumoral injection will be performed as a potential treatment for NF2-related skin schwannomas, ultimately reducing the risks and costs associated with standard surgical removal of such skin tumors if successful.
Neurofibromatosis type 1 (NF1) is the most common genetic tumor predisposition syndrome, affecting up to 1 in 2500 individuals. Cutaneous neurofibromas are benign with self-limited growth; however, tumor burden may be excessive, tumors do not regress, and they can be disfiguring, painful, and itchy. Currently, the only treatment is surgery or laser ablation; however, outcomes are limited by the number of tumors that can be simultaneously removed, operating room availability, and painful recovery, with significant risk of regrowth. There is a strong need for noninvasive topical treatments for cutaneous neurofibromas. Diphencyprone (DPCP) is a "hapten" medication, a small molecule that activates the immune system when applied topically, which has been investigated as a cutaneous immunotherapy for other skin conditions. This is an open label Phase I study looking at safety and tolerability of this treatment as a primary endpoint, and tumor treatment as a secondary endpoint. Approximately 30 subjects will be enrolled at a single center within the US. Subjects with a clinical diagnosis of NF1 who have measurable disease and at least 4 cutaneous neurofibromas, will have DPCP applied topically to their neurofibromas once weekly for 10 weeks.
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.
Children with neurofibromatosis are more likely to have difficulties related to their psychological and neurocognitive functioning (e.g., more likely to have depression, have social difficulties, be diagnosed with ADHD). The purpose of this randomized control study is to determine how effective and useful this study's single session intervention can be in improving psychological and neurocognitive functioning. Enrolled families will consist of one parent/guardian and child. Parents and patients will complete questionnaires and objective tests at baseline, 3 months, and 6 months. Families randomized to the intervention arm will be provided with one single session intervention at Month 1 to learn about their child's testing results and receive psychoeducation and recommendations related to psychological and neurocognitive functioning.
The treatment plan is identical for all participants with the exception of the curcumin dose level that is assigned at study enrollment. Participants are instructed to take the curcumin and olive oil one after the other (order does not matter) twice a day on an empty stomach ideally 30 minutes before breakfast and dinner. Curcumin and high phenolic extra virgin olive oil (HP-EVOO) may continue for up to 12 months in the absence of unacceptable side effects.
