Active clinical trials for "Neurofibromatoses"

A Phase 1 Open Label Study to Assess the Safety, Tolerability, Pharmacokinetics and Clinical Efficacy of Selumetinib, a Selective Mitogen Activated Protein Kinase Kinase (MEK) 1 Inhibitor, in Chinese Paediatric and Adult Subjects with Neurofibromatosis Type 1 (NF1) and Inoperable Plexiform Neurofibromas (PN).

FCN-159 is a highly active MEK1/2 inhibitor that was designed, synthesized and screened on the basis of the structure of trametinib. FCN-159 is an orally available and highly potent selective inhibitor of MEK1/2, which is expected to be a targeted therapy for the treatment of advanced solid tumors and neurofibromatosis type 1.

This phase II trial studies how well trametinib works in treating patients with juvenile myelomonocytic leukemia that has come back (relapsed) or does not respond to treatment (refractory). Trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

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: - Plexiform neurofibromas are tumors that grow in and around nerves. The only way to treat them is with surgery. Some of these tumors cannot be completely removed. The tumors may be too large, too numerous, or in a bad location for surgery. An experimental drug called AZD6244 hydrogen sulfate may be able to prevent the tumors from growing, slow down their growth, or shrink them. This drug has been tested in adults with cancer and in children with some types of brain cancer. This study will test how well this drug works with these types of tumors. Objectives: - To study the safety and effectiveness of AZD6244 hydrogen sulfate in children and young adults with plexiform neurofibromas that cannot be completely removed by surgery. Eligibility: - Children and young adults between 12 and 18 years of age who have plexiform neurofibromas that cannot be completely removed by surgery. Design: Patients will be screened with a physical exam, medical history, blood tests, and imaging studies. They will take the study drug twice a day with 8 ounces of water, every day for 28-day cycles of treatment. During study visits, participants will have blood and urine tests and physical exams. They will also have imaging studies to examine the tumor sizes and locations. They will answer questions about their health. They may have other tests as needed. Participants will continue to receive the study drug as long as they have no severe side effects and the disease is not getting worse.

This phase I/II trial studies the side effects and the best dose of selumetinib and how well it works in treating or re-treating young patients with low grade glioma that has come back (recurrent) or does not respond to treatment (refractory). Selumetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

This is a randomized, double-blind, vehicle-controlled, parallel group dose response study evaluating the safety and effectiveness of 2 concentrations of NFX-179 Gel in subjects with cutaneous neurofibromas. At Visit 1, the investigator will identify 10 Target cNFs that fulfil the enrollment criteria. The Target cNFs must be located on the subject's face, anterior trunk, or upper extremities. Two Target cNFs must be on the face and 8 must be on the anterior trunk or upper extremities. The study medication will be applied topically QD to the Target cNFs for 182days (26 weeks). During the duration of the study subjects will be evaluated for safety and efficacy.

A global study to demonstrate the effectiveness of selumetinib in participants with NF1 who have symptomatic, inoperable plexiform neurofibromas.

The primary objective of this study is to determine whether the administration of tanezumab, an anti-nerve growth factor (NGF) antibody, improves pain relief in schwannomatosis patients receiving background non-NSAID therapy.

This trial, Treatment of NF1-related plexiform neurofibroma with trametinib; a single arm,open-label study with the goals of volumetric partial remission and pain relief (EudraCT 2018-001846-32, Sponsor protocol number BUS2018-1, related Novartis reference number CTMT212ASE01T) is a pediatric clinical trial that investigates the potential use of the drug trametinib (Mekinist®) as treatment for symptomatic or likely to become symptomatic NF1-related plexiform neurofibromas (PN) in children between 1 year and 17 year and 11 months of age. Trametinib is orally administered qd at 0.025 mg/kg up to a maximum of 2 mg from six years of age and 0.032mg/kilo up to 5 years of age, provided either as tablets or as oral solution. It is manufactured and distributed by Novartis under the trade name Mekinist®. The primary endpoint is remission of tumor volume ≥20%, evaluated using volumetric MRI at 18 and 30 months of treatment. The secondary endpoint is reversal of pain from NF1-related PN, evaluated monthly with agespecific pain scales; VAS scale (from 8 years) or Faces Pain Scale (from 3 to 8 years). As an exploratory measure, the potential effects of the treatment on the cognitive function will be assessed using well-established tests such as WISC-V (age range 6:0 - 16:11), NEPSY-II (age range 3:0-16:11), and CPT-3 (age range 8:0 - adult). Cognitive dysfunction is well described in patients with NF1, and the MAPK/ERK-pathway has been indicated to be involved in cognition.
