Filter by:The purpose of this study is to look at the safety (what are the side effects)and efficacy (how well does it work) of Dotarem® when used in taking images of the brain / spine. The results will be compared to the results of MRI taken without Dotarem.
This study is being conducted to determine the safety and effect on cognitive function of the investigational medication, EVP-6124, in individuals with mild to moderate probable Alzheimer's disease.
Evaluation of Wire Electrodes to Activate the Expiratory Muscles to Restore Cough
This study is being conducted to determine the safety and effect on cognitive function of two different doses of an investigational medication, EVP-6124, in individuals with schizophrenia who are on chronic stable atypical anti-psychotic therapy. In addition, behavioral and psychotic symptoms will be evaluated.
Phase I: Primary Objectives: -To define the maximum tolerated dose (MTD) of dasatinib (Sprycel) with radiotherapy (RT) and 6 weeks of concomitant temozolomide (TMZ) administered at 75 mg/m^2/day in patients with newly-diagnosed glioblastoma (GBM). Secondary Objectives: - To characterize the safety profile of dasatinib (Sprycel) in combination with radiotherapy (RT) and concomitant TMZ in patients with newly-diagnosed GBM. - To characterize the safety profile of dasatinib (Sprycel) in combination with adjuvant TMZ in patients with glioblastoma after RT. STUDY DID NOT PROGRESS TO PHASE II PORTION. Phase II: Primary Objectives: -To determine the effectiveness of dasatinib (Sprycel) with radiotherapy (RT) and 6 weeks of concomitant temozolomide (TMZ) administered at 75 mg/m^2/day followed by adjuvant temozolomide with concurrent dasatinib in patients with newly-diagnosed glioblastoma (GBM) as measured by overall survival. Secondary Objectives: - To determine the efficacy of this treatment as measured by radiographic response (RR), progression-free survival (PFS) and time to progression (TTP). - To characterize the safety profile of dasatinib (Sprycel) in combination with RT and concomitant TMZ in patients with newly-diagnosed GBM. - To characterize the safety profile of dasatinib (Sprycel) in combination with adjuvant TMZ in patients with GBM after RT. Exploratory Objectives: -To correlate tumor genotype, tumor expression of dasatinib target proteins (e.g. Src, EphA2, c-kit and PDGFR), and PTEN levels with response to therapy with dasatinib and temozolomide.
The goal of this clinical research study is to find the highest tolerable dose of DNX-2401 that can be injected directly into brain tumors and into the surrounding brain tissue where tumor cells can multiply. A second goal is to study how the new drug DNX-2401 affects brain tumor cells and the body in general.
Inflammatory or degenerative diseases of the brain and spinal cord, such as multiple sclerosis, may be related to problems with an individual s immune system. However, more information is needed on the ways in which the cells of the immune system interact with the central nervous system (CNS). This study will compare tests performed on both healthy volunteers and individuals who have signs or symptoms of immune-related damage to their CNS. This study will include two groups of subjects at least 12 years old. Subjects will either have symptoms of immune-related CNS damage, or will be healthy volunteers selected for comparison purposes. Study participants will visit the NIH Clinical Center on an outpatient basis for an initial evaluation visit. During the visit, patients will provide a comprehensive medical history and undergo a neurological examination, and will provide blood samples for research purposes. The healthy volunteers will be asked to schedule a return visit for a magnetic resonance imaging (MRI) procedure, and may be asked to undergo other tests requested by the study researchers on an as-needed basis. The group of patients with symptoms of immune-related CNS damage will be asked to undergo a series of tests, including the following: - MRI procedures, with a minimum of three brain MRIs and one spinal cord MRI taken approximately 4 weeks apart - A diagnostic lumbar puncture, performed on an outpatient basis - Tests of brain and vision activity - Additional blood and tissue samples Patients with symptoms of immune-related CNS damage may be offered the opportunity to participate in additional followup tests with NIH researchers.
Patients with failed extubation stay significantly longer in an intensive care unit (ICU) and have a higher mortality rate, than those intubated successfully. Reintubation is associated with life-threatening complications and a poor prognosis. Functional respiratory tests are frequently used as weaning parameters, however, they are not accurate enough to predict extubation failure. The incidence of swallowing dysfunction is underestimated, mainly among patients whose intubation lasts longer than 48 h.We previously observed that the assessment of the swallowing function and oropharyngeal motricity, conducted by the physiotherapist before extubation could be helpful for making decisions to extubate patients intubated for over 6 days. The objective of this study is to validate a scale previously devised and used for physiotherapist bedside evaluation of the swallowing function and oropharyngeal motricity, among patients intubated for over 6 days, to determine whether this scale is a good predictor of airway secretion-related extubation failure.Expected results : to validate a scale previously devised called " physiotherapist evaluation of the swallowing function and oropharyngeal motricity before extubation" by the mean of a multicentric study. In our hypothesis the clinical parameters studied could be predictive of extubation failure. Then, this evaluation could help the medical decision in the choice of the good time for extubation. The final objective is to lower the mortality related to extubation failure.
This study is being conducted to determine the safety, tolerability, and pharmacokinetics (PK) of three different doses of an investigational medication, EVP-6124, in individuals with mild to moderate Alzheimer's disease who are also taking an Alzheimer's medication (AChEI [acetylcholinesterase inhibitor]: either donepezil or rivastigmine). In addition, PK of AChEI medications will be assessed. Cognitive function will be evaluated on an exploratory basis.
This study involves the use of Magnetic Resonance Imaging (MRI) contrast agents called gadobutrol (Gadavist) Injection and ProHance Injection. The purpose of this study is to look at the safety (what are the side effects) and efficacy (how well does it work) of gadobutrol when used for taking MR images of the brain and spine. The results of the MRI with gadobutrol Injection will be compared to the results of MR images taken without contrast and with the results of the MR images taken with ProHance.
