All Clinical Trials

The goal of this clinical trial is to learn about treatment for people with B-cell lymphoma that did not respond to treatment or that has gotten worse after treatment. The aim of this trial is to answer the following questions: * If it is realistic to give people radiation treatment before they receive a chimeric antigen receptor (CAR) T-cell treatment for their cancer * If it is safe to give people radiation treatment before they receive a CAR T-cell treatment for their cancer Read Less

The purpose of this study is to investigate the responses of the brain region known as the subgenual anterior cingulate cortex (sgACC) during transcranial magnetic stimulation (TMS) in individuals with depression. Specifically, investigators aim to determine whether the sgACC is engaged when TMS is delivered to specific targets and if the engagement of sgACC changes throughout a full TMS treatment intervention. To achieve this goal, the investigators will employ a combination of TMS and Magnetic Resonance Imaging (MRI) procedures. Study participation will include completing various questionnaires, clinical assessments, receiving a full transcranial magnetic stimulation (TMS) treatment intervention (every weekday for 6 weeks), and undergoing MRI scans, both with and without concurrent TMS.

The primary goal of this study is to assess the accuracy of conventional fat fraction proton MRI for the detection of Brown Adipose Tissue (BAT) in healthy subjects using 18F-2-fluoro-2-deoxy-D-glucosefluorodeoxyglucose -PET as gold standard. In this pilot study, MRI and PET imaging of BAT of healthy adult volunteers will be performed on a combined PET/MRI scanner under mild cold condition. Read Less

This phase II trial studies the effect of atorvastatin in treating patients with ulcerative colitis who have a dominant-negative missense P53 mutation and are at risk of developing large intestinal cancer. Patients with ulcerative colitis are known to have an increased risk of developing large intestinal cancer. Better ways to control ulcerative colitis and more knowledge about how to prevent colon cancer are needed. Atorvastatin is a drug used to lower the amount of cholesterol in the blood and to prevent stroke, heart attack, and angina (chest pain). It blocks an enzyme that helps make cholesterol in the body. It also causes an increase in the breakdown of cholesterol. The information gained from this study may help doctors learn more about atorvastatin as an agent in cancer prevention, and may help to improve public health. Read Less

The main purpose of this study is to gain a better understanding of the distinct mental states and physical reactions that can arise during a psychedelic experience. By repeatedly assessing the same participants in an MRI while under the effects of psilocybin, the investigators want to identify reliable brain and body reactions arising during these psychedelic experiences. It is hoped that this will provide an insight to inspire future research on psilocybin and related psychedelics as well as inform on their therapeutic action. This study will involve up to 12 healthy volunteers with previous psychedelic experience. Participants in this study will be given four doses of psilocybin, with breaks of at least seven days in between dosing visits. The first dosing visit will feature a 10 mg dose of psilocybin, which can be considerate a low to moderate dose, whereas the remaining three dosing visits will feature 25 mg psilocybin, a high dose that is consistent with the dosage chosen for several modern clinical trials with psilocybin. From the initial in-person screening visit to the final follow-up, participants will be in this study for approximately 6-12 weeks and visit the research site 5 times. The first visit will be an in-person screening visit, during which the investigators will assess participants' eligibility to be enrolled. There will be 4 subsequent visits to the scan center for dosing and magnetic resonance imaging (MRI) scanning, and there will be a final remote follow up. Each of the four dosing visits will include four periods of lying within the MRI scanner for scanning, each of these 'in-scanner' sessions will last for \~ 45 minutes. Actual scans, which are also called 'runs' last for \~ 12 mins. During these 'runs', the investigators will ask participants two brief questions about how positive or negative their current experience is every 100 seconds. They will be able to record their answers using a button box which they will be operating with their hand. One day after each dosing visit, the investigators will schedule a phone call with the participant to check how they are doing and perform an informal interview focused on their experience while under the effects of psilocybin.

This project is a single-site, randomized controlled trial designed to investigate the impact of a 7-minute mindfulness intervention on pain among patients undergoing kyphoplasty or radiofrequency ablation. Read Less

Cognitive performance will be studied over time using an iPad game interface called the nine choice human game (5CH) in normal volunteer subjects before during and after experimentally induced thermal (cold or warm) pain or control (no intervention). Read Less

A prospective multi-center observational study. The study will enroll eligible subjects from the United States to optimize the biomarker panel and evaluate the performance of a cfDNA marker panel selected by the Sponsor for CRC and advanced adenoma detection. Read Less

The goal of this prospective, multi-center, randomized, controlled study is to compare the safety and efficacy of the ProtEmbo Cerebral Embolic Protection device to a hybrid control (no embolic protection device ('No Device') and the Sentinel device) in subjects with severe symptomatic native aortic valve stenosis indicated undergoing a TAVR procedure.

The goal of this clinical trial is to evaluate the safety and efficacy of using the VIS Opti-K System to enable monovision by providing temporary improvement in near vision through the treatment of the non-dominant eye of low myopic, emmetropic and low hyperopic presbyope subjects. The main questions it aims to answer are determining uncorrected near visual acuity at 40cm in the treated eye and subjective improvement as measured by the patient satisfaction questionnaire.

Sickle Cell Disease (SCD) is a rare disease occurring in an estimated 100,000 individuals, often poor and underserved, in the US. Silent and overt strokes contribute significantly to morbidity in adults with SCD, resulting in functional impairment, challenges with school and job performance, and premature death. Five NIH-funded randomized controlled trials have identified therapies to prevent silent and overt strokes in children with SCD, including monthly blood transfusion therapy (for preventing initial and recurrent strokes) and hydroxyurea (for preventing initial strokes). Despite the observation that at least 99% of children with SCD in high-income countries reach adulthood, and approximately 60% of adults will experience one or more strokes (\~50% with silent strokes and \~10% with overt strokes), no stroke trials have established therapeutic approaches for adults with SCD. For adults with SCD, inadequate evidence-based guidelines exist for secondary stroke prevention strategies. Applying stroke prevention strategies in children may not be effective for stroke prevention in adults with SCD, particularly given the high rate of co-morbidities. Identifying subgroups of adults with SCD and higher incidence coupled with the contribution of established stroke risk factors in the general population (smoking, diabetes, obesity, renal disease) will provide the requisite data required for the first-ever phase III clinical trials focused on secondary stroke prevention in adults.

This proposed technique, called "Nonlinear Elasticity Mapping (NEM)", is an innovative approach to estimate (i.e., linear and nonlinear) elasticity to provide complementary and relevant information for identification and characterization of breast masses. The proposed technique includes imaging the (nonlinear) elasticity parameter in a quantitative manner and measuring two new and relevant parameters. These parameters, together with linear elasticity, are used to differentiate breast masses. The first parameter is the nonlinearity of the elasticity. Read Less
