This study investigates the pre-clinical nano-based analgesics in cells from human dorsal root ganglia (clusters of neurons). Collecting these neurons may help future research related to safe and effective pain treatment.
The purpose of this research is to combine two complementary modes of treatment, spinal interstitial laser ablation and stereotactic spine radiosurgery (SSRS) for the treatment for spinal tumors near the spinal cord with an objective to improve tumor control, improve pain control, preserve function, and improve quality of life. We will also assess how effective these combined modes of treatment are in patients with spinal metastasis with an epidural component.
The purpose of this study is to measure the benefit of adding abemaciclib to the chemotherapy, temozolomide, for newly diagnosed high-grade glioma following radiotherapy. Your participation could last approximately 11 months and possibly longer depending upon how you and your tumor respond.
The purpose of this study is to assess the safety/tolerability/feasibility of pembrolizumab and radiation therapy before surgical resection in patients with recurrent glioblastoma as defined by treatment-related AEs and the number of patients who do not necessitate a delay in surgical resection, and to assess overall survival. The secondary objectives are to assess progression free survival, and to assess the T cell clonality, CD8 T cell activation and Tumor Infiltrating Lymphocyte (TIL) score after treatment
Objective With this prospective natural experiment trial on neurofibromatosis type 2 (NF2) study, we hope to understand the factors leading to tumor progression and neurological disease burden in NF2. Study Population A total of 269 participants, ages 8-75, with a clinical or genetic diagnosis of NF2 will participate in this study. Design Study participants will be evaluated with a thorough physical and neurologic examination upon enrollment. This initial outpatient evaluation will include magnetic resonance imaging with contrast of brain and spine and blood collection for research use. Participants with measurable hearing will have audiology assessment performed. Participants with untreated vestibular schwannomas will have vestibular assessment performed during the initial visit. Genetic studies performed outside will be acceptable as confirmation of NF2 in enrolled patients. If needed to confirm NF2 with genetic studies, or for research purpose, whole genome/whole exome sequencing may be performed on blood obtained from subjects enrolled in this study. All participants will be evaluated by a speech language pathologist. Subjects will be followed as outpatients for up to ten years, during which clinical, and radiologic evaluation will be performed annually. Auditory testing will be performed annually for participants with measurable hearing. Participants with initially untreated vestibular schwannomas will be followed annually with vestibular testing. Speech and swallowing reassessments will be repeated if worsening of speech or swallowing is reported. Blood will be collected at each visit for blood biomarker testing Outcome measures We hope to understand the biologic basis for speech and swallowing dysfunction in patients with NF2. We will study and report the strength of association of MRI findings, clinical assessments cranial nerve deficits and speech/swallowing dysfunction. We hope to identify imaging biomarkers of hearing loss in NF2. We will attempt to discover the mode of peripheral neuropathy in patients with NF2. Lastly, we will attempt to discover previously unknown serum biomarkers associated with high tumor burden in NF2.
Objective: This protocol is designed to allow evaluation of participants neurosurgical disorders that receive care within the Surgical Neurology Branch. The participants will receive standard-of-clinical-care evaluation and treatment. The clinical data and samples generated during standard of care treatment will be collected as a part of this study. Study Population: Participants 4 years of age and older with neurosurgical-related conditions seeking care from, or referred to the Surgical Neurology Branch for evaluation are eligible for this protocol. Study Design: This is an observational study. Participants will receive standard-of- clinical-care evaluation and treatment for their neurosurgical condition. Clinical evaluation may include laboratory and radiological studies designed to aid in diagnosis or differential diagnosis of the participant s condition or to facilitate treatment. The evaluations may take place in the outpatient clinic areas or in the inpatient units. Some participants will receive standard-of-care medical or surgical treatment for their disorder. Clinical data, tissue samples or body fluids obtained during standard of care treatment, may be used for research. Additional genetic testing may be performed on subjects and their blood relatives if a genetic mechanism underlying the neurological disorder is suspected. Patients in this study may choose to consent to skin biopsies for research purposes, in which case they will sign an additional consent document for thesethis research procedure. Outcome Measures: No additional research outcome measures will be tracked in this study, as this study is collecting data for potential future use. All outcomes will be those of standard clinical evaluation and treatment. A clinical and research database will be kept of patient s diagnosis, progression, and treatment. Clinical database information may be reported or be used in other studies....
