8 Clinical Trials for Various Conditions
Background: NF1 is a genetic syndrome. Tumors appear early in life. Many people with NF1 develop PN. These tumors can become an aggressive cancer called MPNST. People with MPNST may benefit from treatment with a MEK inhibitor (MEKi). Researchers want to learn if there is an increased risk of MPNST formation from MEKi treatment in people with NF1. To do this, they will review data that has been collected in NIH NF1 studies. Objective: To describe the characteristics of people who have taken part in NF1 studies at NIH and to compare the risk of MPNST formation in those treated with MEKi or other PN-directed treatment. Eligibility: People with NF1 who were seen at NIH from Jan. 1, 1998, to Jan. 1, 2020. Design: Participants medical records will be reviewed. Participants who opted out of future use of their data will not be included. Demographic data, like sex, race, and date of birth, will be collected. Data about MEKi and non-MEKi treatments will be collected. Clinical data, such as surgery and treatment details, will be collected. The differences between all participants who were seen at NIH for any NF1 related study will be compared. Participants will be put into 4 groups: History of MEKi therapy Treatment with tumor directed therapy other than MEKi Treatment with both MEKi and non-MEKi tumor directed therapies No tumor directed medical therapy Participants with NF1 who were treated for PN with either a MEKi treatment or a non-MEKi treatment will also be compared. The study will last for 3 to 6 months.
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 study, "A Phase II Study of Cabozantinib (XL l84) for Plexiform Neurofibromas in Subjects with Neurofibromatosis Type I in Children and Adults diagnosed with Neurofibromatosis Type 1 (NF1) and have a type of tumor called a plexiform neurofibroma (PN). Neurofibromas are tumors that develop from the cells and tissues that cover the nerves. Plexiform neurofibromas can be disfiguring, painful, and life-threatening. These types of tumors typically do not respond well to most treatment approaches such as chemotherapy, radiation, and surgery because of their slow growth and location near vital structures of the body such as nerves, blood vessels, and the airway. The primary objective is to determine the response rate of NF1 patients with plexiform neurofibromas treated with Cabozantinib therapy using MRI scans. The objective response rate to cabozantinib is defined as ≥ 20% reduction in tumor volume at the end of 12 cycles.
A global study to demonstrate the effectiveness of selumetinib in participants with NF1 who have symptomatic, inoperable plexiform neurofibromas.
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.
This will be an open-label, single-arm, multicenter intermediate access protocol which provides treatment access to selumetinib for eligible patients with neurofibromatosis type 1 (NF1) who have inoperable, progressive/symptomatic plexiform neurofibromas (PN) without any alternative therapeutic options. All patients will continue to receive drug while they are deriving clinical benefit. Approximately 100 patients in the US will be treated as part of this protocol
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
Background: Neurofibromatosis type 1 (NF1) is a genetic disease that can cause many symptoms. About half of people with NF1 will develop benign (noncancerous) tumors along nerves in the skin, brain, and other parts of the body. Sometimes, though, these tumors can become cancerous. Researchers do not yet know how to predict which tumors will become cancerous. Objective: To test a new method for predicting which benign NF1 tumors will become cancerous. Eligibility: People aged 3 years and older with a clinical or genetic diagnosis of NF1. Design: * Participants will be screened with a review of their medical history. All participants will have a baseline visit. They will have bood tests and imaging scans. They will have a physical exam. They will answer questions about their family history. Participants aged 8 years and older will take tests of their thinking skills and their emotional health. * Some participants may be asked to undergo more tests. These may include another type of imaging scan and a biopsy: A small sample of tissue may be removed from the tumor. * Participants will be divided into two groups: those believed to be at low risk and those believed to be at high risk of developing cancer. * Participants in the high-risk group will be asked to return for their next visit in 1 month to 3 years. * Participants in the low-risk group will be asked to return for their next visit in 6 months to 5 years. * Participants may also have follow-up visits by phone throughout the study. They will be in the study for 10 years.
