Active clinical trials for "Neurofibroma"

This study is for slow growing tumors called plexiform neurofibromas (PNF) which are a relatively common problem in people with neurofibromatosis type 1 (NF1). These tumors are benign but as they grow, they can become disfiguring as well as disabling or even life threatening. They often cause pain, difficulty using arms or legs because of spinal cord compression, and/or nerve damage. At present, the only available therapy for plexiform neurofibromas is to try to surgically remove as much of the tumor as is possible. Because these tumors grow into the surrounding areas, total surgical resection is often impossible. Most tumors will re-grow after surgery if the entire tumor cannot be removed. To date, other treatments including chemotherapy and radiotherapy have not been able to shrink these tumors. Interferon is a drug that is used for different types of tumors as well as for hepatitis. It has been used in the treatment of plexiform neurofibromas (PNF) with some subjects showing improvement in symptoms and/or a decrease in the size of the tumor. Most subjects had no further growth of their tumor while on the PEG-Intron. The drug used in this study is PEG (pegylated)-Intron. PEG-Intron is a long acting form of interferon which keeps the drug from being broken down in the body for a longer period of time and potentially could be more effective than the short-acting interferon. PEG-Intron has been approved by the Food and Drug Administration (FDA) for the treatment of Hepatitis C. The goals of this study are: To determine how your child's plexiform neurofibroma responds to PEG-Intron when given weekly. To determine the side effects of PEG-Intron when given weekly to participants with plexiform neurofibromas. To evaluate a new method of measuring changes in the size of tumors called volume analysis. This method measures the entire volume of a tumor in three dimensions. The standard method of measuring tumors uses only the length and/or width of the tumor. By studying the different ways of measuring tumors the investigators hope to be able to determine which method is the most accurate and useful.

This study will evaluate bioavailability and food effect of selumetinib (AZD6244) in healthy male participants. A total of 24 healthy male participants will be included to ensure at least 20 evaluable participants. The study is divided in 2 study parts; the same participants will participate in both parts of the study. Part 1 of the study is to investigate the pharmacokinetics (PK) of the selumetinib granule compared to the PK of selumetinib capsule, when administered with water under the fasted conditions. Part 2 of the study is to investigate the PK of selumetinib granule and capsule under fed conditions. Participants will also receive a single 500 mg dose of acetaminophen at the same time as selumetinib administration.

This study will look at the feasibility of using magnetic resonance fingerprinting (MRF) in children, adolescents and young adults (AYA) with and without brain tumors. This study will also look at subjects with and without neurofibromatosis type 1(NF1), a genetic disorder that affects the growth of nervous system cells. Further, it will explore potential ways of using of MRF signal measurements in children, adolescents, and young adults with brain tumors, including tissue characterization, looking at whether the treatment was effective, and finding metastasized tumors of unknown origin (occult tumors). To explore the feasibility and potential applications of MRF, this study will recruit up to 80 subjects but will stop once 10 subjects have usable data in each of six groups.

This phase II open label study will evaluate adolescents (≥ 16 years of age) and adults with neurofibromatosis type-1 (NF1) and plexiform neurofibromas treated with the MEK inhibitor PD-0325901. The primary aim of the study will be to assess quantitative radiographic response in a target lesion. Subjects will receive PD-0325901 by mouth on a bid dosing schedule of 2 mg/m2/dose with a maximum dose of 4 mg bid. Each course is 4 weeks duration, and subjects will receive drug on a 3 week on/1 week off schedule. Subjects may receive additional courses beyond course 8 only if there is at least 15% reduction in volume of the target tumor. Subjects who have a 20% or greater reduction in target tumor volume at the end of 12 courses can continue on therapy for up to an additional year (maximum of 24 total courses). However, subjects who do not achieve at least 15% reduction in volume of the target tumor after 8 courses (~8 months) will be considered treatment failures and taken off study. The Primary purpose of this protocol is to determine whether PD-0325901 results in objective radiographic responses based on volumetric MRI measurements in adolescents and adults with NF1 and growing or symptomatic inoperable PN. There are several secondary aims of this protocol: To evaluate the feasibility and toxicity of chronic PD-0325901 administration in this patient population To estimate the objective response rate of up to 2 non-target plexiform neurofibromas to PD-0325901 by MRI To characterize the pharmacokinetic profile of PD-0325901 when administered to this patient population To evaluate quality of life and pain during treatment with PD-0325901

1)Preliminarily evaluate the treatment effect of continuous vein injection of recombinant human endostatin on NF2; 2)Preliminarily evaluate the safety and the patient's tolerance of the treatment of endostatin; 3)Provide an objective basis for an enlarged randomized double-blind trial.

Background: Patients with the genetic disorder neurofibromatosis Type 1 (NF1) are at increased risk of developing tumors of the central and peripheral nervous system. These include plexiform neurofibromas. The conventional treatment of these internal plexiform neurofibromas is surgery. This surgery can be possible on a single and limited tumor. On the other hand these tumors are often surgically intractable due to their multiplicity and their infiltrating characteristics Increased activity of mammalian target of rapamycin(mTOR) protein is seen in neurofibromas. mTOR inhibitor rapamycin , or its derivatives such as everolimus may slow or stop tumor growth in patients with NF1. Objectives: Primary objectives To determine whether everolimus has an effect on the volume of surgically intractable and life-threatening internal plexiform neurofibromas in patients with neurofibromatosis 1. Secondary objectives To determine whether everolimus has an effect on the number and the volume of cutaneous neurofibromas; to determine whether everolimus modify the signaling pathways in cutaneous neurofibromas. Eligibility: - Adults with neurofibromatosis type 1 with at least one internal plexiform neurofibroma, life-threatening or causing significant morbidity through compression of organs. This or these internal plexiform neurofibroma(s) should be intractable by surgery. Design: An open-label, single arm, non-randomized, single stage phase IIa study. Baseline phase: Baseline evaluations will be performed within 2 weeks, and up to a maximum of 4 weeks for specific exams, before the first dose of study drug. Treatment phase/duration of treatment: All patients will be treated with RAD001 10 mg p.o daily dose for one year except in case of unacceptable toxicity, death, or discontinuation from the study for any other reason. Follow-up phase: All patients will have two follow-up visits scheduled at 18 and 24 months after the first dose of the study drug to follow for adverse events (AEs) and serious adverse events (SAEs) that may have occurred after discontinuation from the study and for internal plexiform neurofibromas assessment. Radiological review: All Magnetic Resonance Imaging (MRIs) obtained at baseline, during the treatment period and the follow-up period will be reviewed by the Neuroradiologist of the study.

The purpose of this Pilot Study is to determine if NF1 patients with plexiform neurofibromas treated with Tasgina® respond to therapy.

The purpose of this study is to determine if Lapatinib has any effect on tumors found in patients with Neurofibromatosis Type 2 (NF2). NF2 is a condition that mainly affects the skin and nervous system. It causes non-cancerous tumors (which are known as neuromas) to grow on the nerves around a person's body. Some signs of NF2 include a gradual loss of hearing and tumors growing on the skin, the brain and the spinal cord which can lead to complications. Lapatinib is an oral drug that is approved by Food and Drug Administration (FDA) for other types of tumors, it is not approved by the FDA for treatment of NF2 related tumors. The investigators know a lot about how well it is tolerated, but the investigators do not know if it is effective in treating your condition, therefore it is considered to be an investigational medication. This study will test whether Lapatinib may shrink tumors commonly found in patients with NF2 or stop them from growing. This will help us to decide if Lapatinib should be used to treat NF2 patients in future. Lapatinib is a drug that has been used for over 10 years to treat various forms of cancer. It has not been studied for the treatment of tumors in NF2 patients.

This study is a prospective, randomized, double-blind, placebo-controlled evaluation of the safety of a topically applied formulation of rapamycin to cutaneous fibromatous lesions in subjects with Tuberous Sclerosis Complex (TSC) and Neurofibromatosis I (NF1). Subjects will apply either a Polyvinylidene fluoride (PVDF) coating (Skincerity) containing rapamycin or the PVDF coating alone nightly to fibromatous lesions for a duration of six months. The primary goal of this study is to evaluate the safety of the topical product in patients with TSC and NF1. The secondary goal of this study is to evaluate the effectiveness of the topical product for treatment of cutaneous fibromatous lesions.

The purpose of this study is to find out what effects, good and/or bad, sunitinib has on patients and their tumors. At this time, no drugs are routinely used to treat meningioma, hemangioblastoma or hemangiopericytoma. Only surgery and radiation therapy are known to be useful. Sunitinib is a drug approved for advanced kidney cancer. Sunitinib is also being studied for other tumors. It may be useful in the treatment of brain tumors because it can prevent formation of new blood vessels that allow tumor cells to survive and grow.
