Active clinical trials for "Neurofibromatosis 1"

Background: - Some people with cancer have solid tumors. Others have refractory leukemia. This may not go away after treatment. Researchers want to see if a drug called Turalio(R) can shrink tumors or stop them from growing. Objectives: - To find the highest safe dose and side effects of Turalio(R). To see if it helps treat certain types of cancer. Eligibility: - People ages 3-35 with a solid tumor or leukemia that has returned or not responded to cancer therapies. Design: Participants will be screened with: Medical history Physical exam Blood and urine tests Heart tests Scans or other tests of the tumor Participants will take Turalio(R) as a capsule once daily for a 28-day cycle. They can do this for up to 2 years. During the study, participants will have many tests and procedures. They include repeats of the screening tests. Participants will keep a diary of symptoms. Participants with solid tumors will have scans or x-rays. Participants with leukemia will have blood tests. They may have a bone marrow sample taken. Some participants may have a biopsy. When finished taking Turalio(R), participants will have follow-up visits. They will repeat the screening tests and note side effects.

This is a phase II, open-label, prospective study of T cell receptor alpha/beta depletion (α/β TCD) peripheral blood stem cell (PBSC) transplantation for children and adults with hematological malignancies

Background: NF1 is a genetic disease that causes tumors called atypical neurofibromas. These tumors, which arise from nerves, can cause serious medical problems. The only treatment is surgery. Researchers want to see if a drug called abemaciclib can help. Objective: To find a safe, tolerable dose of abemaciclib for treating atypical neurofibromas. Eligibility: People ages 12 and older who have NF1 and have one or more atypical neurofibromas that cannot or will not be removed with surgery Design: Participants will be screened with: Medical history and physical exam Blood, urine, and heart tests MRI: Participants will lie in a machine that takes pictures of the body. A padding or coil will be placed around their head. They may have a contrast agent injected into a vein. Biopsy sample: A small piece of tumor will be removed using a large needle. Participants will have frequent visits during the study. These will include repeats of the screening tests as well as the following: PET scan: Participants will lie in a machine that takes pictures of the body. They will have a contrast agent injected into their arm. Questionnaires about the effects of abemaciclib on pain and quality of life Possible photographs of tumors Participants will take abemaciclib capsules orally twice daily in 28-day cycles. They will take the drug for up to 2 years. Some may be able to take it for longer. Participants will have a follow-up visit about 30 days after their last dose of the study drug. Then they will have visits every 3 months for 1 year.

This phase I/II trial is designed to study the side effects, best dose and efficacy of adding hydroxychloroquine to dabrafenib and/or trametinib in children with low grade or high grade brain tumors previously treated with similar drugs that did not respond completely (progressive) or tumors that came back while receiving a similar agent (recurrent). Patients must also have specific genetic mutations including BRAF V600 mutations or BRAF fusion/duplication, with or without neurofibromatosis type 1. Neurofibromatosis type 1 is an inherited genetic condition that causes tumors to grow on nerve tissue. Hydroxychloroquine, works in different ways to stop the growth of tumor cells by killing the cells or stopping them from dividing. Trametinib and dabrafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving hydroxychloroquine with trametinib and/or dabrafenib may lower the chance of brain tumors growing or spreading compared to usual treatments.

AL2846 is a multi-target receptor tyrosine kinase inhibitor. The purpose of this study is to evaluate the safety and efficacy of AL2846 capsules in Chinese patients with type I neurofibromatosis (NF1) (neurofibromas and malignant peripheral nerve sheath tumors).

The investigators wish to determine the time to disease progression for benign neurofibromas treated with Levulan Kerastick topical photosensitizer and red light photodynamic therapy (PDT) in patients with neurofibromatosis type 1 (NF1). The investigators also wish to measure tumor size for control and treatment tumors in order to gain insights into tumor growth rates.

This phase I trial studies the side effects and the best dose of a vaccine therapy in treating patients with malignant peripheral nerve sheath tumor that cannot be removed by surgery (unresectable) or has come back after a period of improvement (recurrent). Vaccines made from a gene-modified virus may kill tumor cells expressing a gene called neurofibromin 1 (NF1) without affecting surrounding normal cells and may also help the body build an effective immune response to kill tumor cells.

Phase I and II study of the MEK inhibitor Selumetinib given twice daily on 5 out of 7 days in children with NF1 and inoperable plexiform neurofibromas or progressive/relapsed optic pathway gliomas. This study will test the early and late toxicities of selumetinib when it is given in this intermittent schedule (in 5 out of 7 days) and will also test the effectiveness of the drug in reducing the size of plexiform neurofibromas and optic pathway gliomas in children with NF1. It will also test the effectiveness of the drug in improving the participants function in day to day life.

This phase III trial studies if selumetinib works just as well as the standard treatment with carboplatin/vincristine (CV) for subjects with NF1-associated low grade glioma (LGG), and to see if selumetinib is better than CV in improving vision in subjects with LGG of the optic pathway (vision nerves). Selumetinib is a drug that works by blocking some enzymes that low-grade glioma tumor cells need for their growth. This results in killing tumor cells. Drugs used as chemotherapy, such as carboplatin and vincristine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether selumetinib works better in treating patients with NF1-associated low-grade glioma compared to standard therapy with carboplatin and vincristine.

This is a multi-arm phase II platform-basket screening study designed to test multiple experimental therapies simultaneously in patients with neurofibromatosis type 2 (NF2) with associated progressive tumors of vestibular schwannomas (VS), non-vestibular schwannomas (non-VS), meningiomas, and ependymomas. This Master Study is being conducted as a "basket" study that may allow people with multiple tumor types associated with NF2 to receive new drugs throughout this study. Embedded within the Master Study are individual drug substudies. Investigational Drug Sub-study A: Brigatinib Investigational Drug Sub-study B: Neratinib
