Filter by:A Phase 1 study in healthy subjects to determine the safety, tolerability, psychomotor function, and cognitive effects of perampanel when administered alone and with alcohol.
This study is designed to evaluate the pharmacokinetics, efficacy, and safety of perampanel oral suspension on seizure frequency in pediatric participants maintained on one to three stable antiepileptic drugs
Listeriosis is a foodborne infection responsible for severe disease. Three main forms are described: septicaemia, central nervous system infections and maternal-fetal infections. Available data on the disease, are mostly retrospective and do not provide an accurate picture of the clinical / biological / genetic risk factors for the disease, nor identify any element to determine which patients are at higher risk of death, severe neurological impairment or fetal loss. The primary purpose of the study is to identify clinical, biological and genetic risk factors for systemic listeriosis and the determinants of listeriosis-associated mortality in the setting of a large prospective nation-wide study.
Background: - People with motor neuron disorders have changes in the parts of the brain that control movement. Some tests that are currently used to study these changes are magnetic resonance imaging (MRI) and transcranial magnetic stimulation (TMS). We don t know if MRI scans and TMS give the same results if done at different times in the same person. Researchers want to see if these tests produce different results if given to healthy adults on two separate occasions. Objectives: - To test the reliability of different tests of the brain used to study motor neuron disorders. Eligibility: - <TAB>Healthy individuals at least 35 years of age who have no history of neurological disorders and take no medications. - <TAB>Pregnant women may not participate. Design: - Participants will be screened with a medical history and physical exam. - Participants will have two testing visits 1 to 6 months apart. - The first visit will have three parts. The first part is a neurological exam to test strength, sensation, reflexes, and coordination of movement. The second part will be TMS tests. The third part will involve an MRI scan to study the parts of the brain that control movement. - At the second visit, participants will have MRI scanning only.
This is a phase I study to investigate the safety and pharmacokinetics of weekly 5-fluorouracil (5-FU) administered as a bolus dose in children and young adults with recurrent or refractory ependymoma. The results from this study will inform a subsequent phase II St. Jude investigator-initiated trial.
This study will measure resting state network central nervous system activity by functional magnetic resonance imaging (fMRI) during 4 separate interactions with a clinician. 1. Hypothesis 1. Because they are different sensory systems, there will be different patterns of Mirror Neuron System (MNS)and Resting State Network (RSN) Central Nervous System (CNS) activity for visual vs. tactile stimulation, regardless of Loving Kindness Meditation (LKM). Hypothesis 2. Because of unconscious, non-verbal signals, such as the practitioner's facial expression and respiratory rate, subjects' patterns of MNS and RSN CNS activity will differ for LKM+ vs. LKM- stimulation for both visual and tactile interventions. Hypothesis 3. Because there is greater opportunity to detect signals from two sensory systems than one, the differences between CNS MNS and RSN activity patterns for LKM+ and LKM- will be greater for combined visual + tactile than for either visual or tactile stimulation alone.
Understudied drugs will be administered to children per standard of care as prescribed by their treating caregiver and only biological sample collection during the time of drug administration will be involved. A total of approximately 7000 children aged <21 years who are receiving these drugs for standard of care will be enrolled and will be followed for up a maximum of 90 days. The goal of this study is to characterize the pharmacokinetics of understudied drugs for which specific dosing recommendations and safety data are lacking. The prescribing of drugs to children will not be part of this protocol. Taking advantage of procedures done as part of routine medical care (i.e. blood draws) this study will serve as a tool to better understand drug exposure in children receiving these drugs per standard of care. The data collected through this initiative will also provide valuable pharmacokinetic and dosing information of drugs in different pediatric age groups as well as special pediatric populations (i.e. obese).
RATIONALE: Methylphenidate hydrochloride or modafinil may help reduce daytime sleepiness and improve the quality of life of patients with excessive daytime sleepiness after cancer therapy. It is not yet known whether methylphenidate hydrochloride or modafinil are more effective than a placebo in reducing daytime sleepiness in these patients. PURPOSE: This randomized phase II trial is studying methylphenidate hydrochloride or modafinil to see how well they work compared with a placebo in treating young patients with excessive daytime sleepiness after cancer therapy.
RATIONALE: Acupressure wristbands may prevent or reduce nausea and caused by chemotherapy. It is not yet known whether standard care is more effective with or without acupressure wristbands in controlling acute and delayed nausea. PURPOSE: This randomized phase III trial is studying how well acupressure wristbands work with or without standard care in controlling nausea in young patients receiving highly emetogenic chemotherapy.
The purpose of this research study is to determine if radiation using proton beam therapy will kill the germ cell tumor in the participant's central nervous system. This type of radiation has been used previously on many patients with different types of cancers. There are two types of external radiation treatments, proton beam and photon beam. In this study we will be examining the effects of proton beam radiation therapy. Studies have suggested that this kind of radiation can spare normal tissue more than photon radiation therapy. The physical characteristics of proton beam radiation let the doctor safely increase the amount of radiation delivered to the tumor. We believe that proton beam therapy will potentially reduce side effects that participants would normally experience with photon radiation therapy.
