Sorafenib to Treat Children and Young Adults With Neurofibromatosis Type 1 and Inoperable Plexiform...

Neurofibromatosis Type IPlexiform Neurofibroma

Background: Patients with neurofibromatosis type 1 are at increased risk of developing tumors called plexiform neurofibromas (PN) that arise from nerves. These tumors are usually non-cancerous, but they can cause serious medical problems. Sorafenib was recently approved to treat patients with kidney cancer and is now being tested in children with cancer. It affects several pathways thought to be important for the development and growth of PN and may therefore shrink these tumors or slow their growth. Objectives: To determine the highest dose of sorafenib that can safely be given to children and young adults with PN. To identify the side effects of sorafenib in these patients. To study how the body handles sorafenib by measuring the amount of drug in the bloodstream over time To determine how the drug affects blood flow and blood cells and proteins. To determine if sorafenib can shrink or slow the growth of PN. To determine the effects of sorafenib on learning, attention, memory, and quality of life. Eligibility: Patients between 3 and 18 years of age with NF1 who have inoperable PN that can cause significant disability. Design: Patients take sorafenib tablets twice a day in 28-day treatment cycles. They may continue treatment until their tumor grows or they develop unacceptable drug side effects. In this dose escalation study, the dosage is increased with every 3 to 6 children who are enrolled until the highest safe dose is determined. In any case, the dose will not exceed that used in children with cancer. Patients are monitored regularly with physical examinations, blood and urine tests, MRI scans and quality-of-life questionnaires. Patients whose bones are still growing have periodic x-rays of the hips and lower legs to monitor for possible changes in the structure of growing bones. Patients have periodic tests of learning and memory before starting treatment and before cycles 4, 12, 18 and 24. Patients have pharmacokinetic studies to examine how the body handles sorafenib. blood samples are drawn before the first dose of sorafenib and then at 30 minutes, 1 hour, 2 hours, 3 hours, 5 hours, 8 hours, 10 to 12 hours, 24 hours and 30 to 36 hours following the first dose. ...

Phase II Study of the Multichannel Auditory Brain Stem Implant for Deafness Following Surgery for...

Neurofibromatosis 2

OBJECTIVES: I. Define the tonotopocity of multichannel brain stem stimulation and use this information to better program the auditory brain stem implant for an individual. II. Optimize device fitting by combining monopolar and bipolar stimulation, and individual psychoacoustic channels for each patient, to increase the number of usable information channels for each patient and reduce or eliminate undesirable side effects. III. Evaluate performance and learning effects using optimized fitting procedures.

Study to Investigate Safety, Pharmacokinetic (PK), Pharmacodynamic (PD) and Clinical Activity of...

Cancer

This was a 4-part (Part A, Part B, Part C and Part D), Phase I/IIa, multi-center, open label, study in pediatric subjects with refractory or recurrent tumors. Part A was a repeat dose, dose escalation and expansion phase that identified the recommended phase II dose (RP2D) of trametinib monotherapy. Part B evaluated the preliminary activity of trametinib monotherapy in 4 disease-specific cohorts of subjects. Part C was aimed to determine the safety, tolerability and preliminary activity of the RP2D of trametinib in combination with a limited dose escalation of dabrafenib. Part D evaluated the preliminary activity of trametinib in combination with dabrafenib in 2 disease-specific cohorts of subjects. The overall goal of this trial was to efficiently establish safe, pharmacologically relevant dose of trametinib monotherapy and trametinib in combination with dabrafenib in infants, children and adolescents and determine preliminary activity of trametinib monotherapy and trametinib in combination with dabrafenib in selected recurrent, refractory or unresectable childhood tumors.

Everolimus for Treatment of Disfiguring Cutaneous Lesions in Neurofibromatosis1 CRAD001CUS232T

Neurofibromatosis 1

This trial is evaluating the use of oral Everolimus to determine if there is a reduction in the size of the disfiguring cutaneous lesions in patients with Neurofibromatosis 1 over a 6 month period. The evaluation will be done by 3D photography measuring volume with the LIFEVIZ Micro system.

Bevacizumab in Treating Patients With Recurrent or Progressive Meningiomas

Acoustic SchwannomaAdult Anaplastic Meningioma8 more

RATIONALE: Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. PURPOSE: This phase II trial is studying how well bevacizumab works in treating patients with recurrent or progression meningiomas.

Topical Imiquimod 5% Cream for Treatment of Cutaneous Neurofibromas in Adults With Neurofibromatosis...

Neurofibromatosis Type 1Cutaneous Neurofibromas

The purpose of this study is to determine if imiquimod cream can reverse the growth of neurofibromas. Imiquimod is a skin cream that works by stimulating the body's immune system to respond to tumors. Imiquimod cream is approved for use in patients with various skin lesions, including actinic keratosis, superficial basal cell carcinoma, and external genital warts. Information from these studies, as well as previous laboratory studies, suggest that imiquimod cream may help shrink neurofibromas or keep them from growing.

A Phase II Study of the mTOR Inhibitor Sirolimus in Neurofibromatosis Type 1 Related Plexiform Neurofibromas...

Neurofibromatosis Type 1

Treatment Overview This phase II study will evaluate the activity of sirolimus in children and adults with NF1 and inoperable plexiform neurofibromas that have the potential to cause significant morbidity. The following disease strata will be studied: Stratum 1: Progressive plexiform neurofibroma(s) that have the potential to cause significant morbidity. The endpoint will be time to tumor progression based on volumetric tumor measurements. Stratum 2: Plexiform neurofibromas without documented radiographic progression at trial entry. The endpoint will be radiographic response. As of May 2009, Stratum 2 was closed to enrollment. Stratum 1 is active.

Medical Treatment of "High-Risk" Neurofibromas

Neurofibromatosis 1

Patients with neurofibromatosis type 1 (NF1) commonly develop non-cancerous tumors called plexiform neurofibromas. These tumors can be defined as "high-risk" when they result in severe pain, physical disability, organ dysfunction and/or become life-threatening. Presently, there is no effective medical therapy to offer patients with "high-risk" plexiform neurofibromas, and surgery does not provide lasting help. This study will evaluate the effectiveness of two treatment combinations in patients with "high-risk" plexiform neurofibromas.
