Clinical trials Below are current clinical trials.60 studies in Neurosurgery (open studies only). Filter this list of studies by location, status and more. A Study to Develop Liquid Biopsy for Pediatric Brain Tumor Patients Rochester, Minn. The purpose of this study is to confirm detection of the H3K27M mutation in patient biofluids (CSF, blood, urine, saliva) and uncover the molecular histone (alkaline protein) profile of H3K trimethylation and H3S phosphorylation in the circulating nucleosomes isolated from the biofluids of patients with H3K27M tumors. A Study to Evaluate Electrophysiology of Deep Brain Stimulation Rochester, Minn. The primary purpose of this study is to map the electrophysiological properties of deep brain stimulation (DBS) targets and associated areas by analyzing signals recorded for clinical purposes. Electrophysiological properties such as spike statistics, power spectral density, spike-field coupling, and phase-amplitude coupling may be correlated to anatomic structures. An atlas with these properties could improve DBS lead targeting. Treatment Resistant Depression Subcallosal Cingulate Network Rochester, Minn. The purpose of this study is to evaluate the effectiveness and safety of bilateral stimulation of the SCCwm using the Infinity DBS system as an adjunctive treatment of non-psychotic unipolar Major Depression Disorder (MDD) for adults who are experiencing an Major Depressive Episode (MDE) with inadequate response to 4 or more antidepressant treatments. Dynamic Evaluation Of Spinal Alignment And Balance In Adults With Spinal Deformity Using Momentum Spine Rochester, Minn. The purpose of this study is to determine whether the Momentum Spine™ application, with its newly developed dynamic spinal metrics, can accurately and feasibly assess postural parameters in adults with spinal deformity across the continuum of care: conservative management, before and after spinal surgery. A Study to Analyze Intracerebral Hemorrhage Hematoma Jacksonville, Fla. The purpose of this study is to to take the usual waste material from the removal of hematoma and apply an array of -Omics approaches (including for example genomics, transcriptomics, lipidomics, proteomics, and metabolomics) to identify biomarkers that assess prognosis and identify key therapeutic targets. A Study to Develop a Biorepository of Blood Samples from Cancer Patients Participating in the Gemini (IRB 19-006717) Protocol Jacksonville, Fla., Scottsdale/Phoenix, Ariz. The purpose of this study is to develop a biorepository of blood samples from cancer patients participating in the Gemini (IRB 19-006717) protocol. These samples will be used for future biomarker discovery and other translational studies. Collection of Discarded Cerebrospinal Fluid for Research Purposes Rochester, Minn. The purpose of this study is to collect and store cerebrospinal fluid (CSF)from patients with normal CSF. This stored CSF will be used in the future as a culture media to better understand how therapeutic cells delivered into the CSF will behave. A Study to Establish a Registry for Treatment of Post-hemorrhagic Hydrocephalus in Neonates Rochester, Minn. The purpose of this study is to establish a prospective, standardized data collection for the patients who undergo surgical treatment of progressive post-hemorrhagic hydrocephalus in neonates with the focus on comparing neuroendoscopic lavage (NEL) with other standard treatment options such as external ventricular drainage (EVD), ventricular access device (VAD) and ventricular subgaleal shunt (VSGS). A Study of Lutetium Lu 177 Dotatate (Lutathera®) in Patients with Inoperable, Progressive Meningioma after External Beam Radiation Therapy Rochester, Minn. The purpose of this study is to estimate the efficacy of LUTATHERA treatment in patients with recurrent grade 1 meningioma as measured by 6-month PFS rate, and to estimate the efficacy of LUTATHERA treatment in patients with recurrent grade 2 or 3 meningioma as measured by 6-month PFS rate. Pituitary tumor registry Rochester, Minn. The purpose of this data registry involves the collection of standard of care clinical treatment regimens, diagnostic information and surgical outcomes which may include human specimens and associated genomewide expression data.

The patient comes first. So the mission and research here is to advance how we can best help the patient, how to make sure the patient comes first in care. So in many ways, it's a cycle. It can start with as simple as an idea worked on in a laboratory, brought to the patient bedside, and if everything goes right — and let's say it's helpful or beneficial — then brought on as a standard approach. And I think that is one of the unique characteristics of Mayo's approach to research — that patient-centeredness — that really helps to put it in its own spotlight.
