This study is enrolling subjects with an abnormal heart rhythm called ventricular tachycardia (VT - rapid heart beat coming from the bottom of the heart) that has come back despite treatment. This is a randomized study meaning subjects will be assigned to one of two groups and then undergo either a standard catheter ablation or a new treatment called cardiac radioablation for their VT. You will have a 50:50 chance of being assigned to either group. A standard catheter ablation is done by placing catheters (long hollow tubes) into a large blood vessel at the top of the leg, guiding them to the heart to first identify the signals causing the VT and then use radiofrequency (heat) energy to burn and stop these signals to stop the VT. The cardiac radioablation is an investigational treatment meaning it is not yet approved for routine clinical use by the Food and Drug Administration (FDA). Cardiac radioablation is performed in the radiation oncology department and uses radiation therapy to treat the signals causing the VT. Participation in this study will last up to 5 years and inlcude about 15 visits. Study related procedures include medical record review and data collection, electrocardiogram (tracing of heart's electrical activity), echocardiogram (ultrasound test of the heart), CT scans, blood work, questionnaires, implantable cardioverter defibrillation (ICD - device implanted in your chest that monitors and treats abnormal heart rhythms), and ablation procedure per randomization. Risks include fatigue, changes in the appearance of the lungs in the cardiac radioablation group, fatigue, pain, low or high blood pressure or excessive bruising or bleeding at the catheter insertion side in the cardiac ablation arm. There are also study procedure related risks, and risks that are not known. There is potential benefit to you and to others in learning how to better treat others in the future with this condition.

The purpose of this study is to get feedback on an existing augmented reality (AR) software developed by researchers at Wayne State University (phase I) and then use the refined software, along with Prolonged Exposure (PE) therapy to treat Veterans and military personnel with posttraumatic stress disorder (PTSD).

AR involves wearing goggles through which you can see the real world, however virtual objects can be added to the environment (for example, like in the popular phone game Pokemon Go).

The technology was originally designed to help first responders, specifically police and firefighters, to overcome their avoidance of normal life situations caused by their trauma experience and PTSD. This includes a crowded party, a grocery store, a police roll call room and a fire station. This technology is now being expanded to include other common scenarios that military personnel and Veterans with PTSD may avoid.

This study will occur in 2 phases. Phase 1 will focus on getting feedback on the AR program from people who have completed PE therapy before to refine the technology. In phase 2, 40 Veterans and military personnel will be randomly selected to receive PTSD therapy + the refined AR technology or PE therapy alone.

This study is open to Veterans and active duty military personnel. All study activities will take place at the Ralph H. Johnson VA Health Care System and surrounding community-based outpatient clinics. This study is not open to civilians/non military personnel at this time.

The purpose of this clinical trial is to evaluate the safety and effectiveness of ONO-2808 in patients with Multiple System Atrophy with cerebellar variant (MSA-C)and Multiple System Atrophy with parkinsonian variant (MSA-P).MSA is a rare, rapidly progressing, fatal, adult-onset neurodegenerative disorder of the central and autonomic nervous systems that is characterized clinically by a variable combination of parkinsonism, cerebellar impairment, and autonomic and motor dysfunctions ONO-2808 is an investigational drug meaning that its safety, effects, and how it works are still being studied. This is a randomized (assigned by chance), placebo-controlled study, which means that some participants will receive a fake treatment (placebo) while others get the real treatment. The placebo treatment looks like the ONO-2808 medications but doesn't contain any active ingredient. The medication is in pill form and will be administered orally. This research is also double-blind, meaning that neither the participants nor the researcher will know which treatment they will be receiving. If participants choose to take part in the study they will be asked to attend up to 16 visits and the study will take up to 34 weeks. During the study, participants will be asked to go through a screening period (up to 6 weeks). The purpose of this screening period is to make sure study participants meet all the study criteria. If participants meet all study criteria, they may be asked to volunteer for the double-blind treatments. The duration of the double-blind treatment is 24 weeks which consists of 14 visits, some visits will be done at the study center/ hospital and the remaining visits will be done by a nurse from IQVIA's Research Nurse and Phlebotomy Solutions (RNPS) at participants' home. During visits, participants should anticipate tests including electrocardiograms (ECGs), vitals measurements (including temperature, blood pressure, and heart rate), and a physical/neurological examination. Some of the risks include nausea, vomiting, abdominal pain, loss of appetite, dark urine, yellow eyes, and persistent fatigue.

This study is for patients with hypertrophic cardiomyopathy (HCM). HCM is a condition where the heart muscle becomes abnormally thickened, which can sometimes block the blood flow out of the heart and results in the heart muscle working harder to pump blood to the body. Participants who have completed participation in a previous HCM study investigating the study drug, called aficamten (CK-3773274), will be eligible to participate in this study.

The study is done to collect long-term safety and tolerability data, including assessments of cardiac structure and function during chronic dosing with aficamten. Aficamten is a tablet taken by mouth. This is an open label study (the participants and study team will know the dose of aficamten taken at any given time). If your screening results show you are eligible to continue in the study, you will visit the research site for the "first dosing day" (Day 1), followed by visits at Weeks 2, 4, 6, 12, then every 12 weeks thereafter. Study related procedures include blood work, echocardiograms (ultrasound test of the heart), electrocardiogram (recording of heart's electrical activity), physical exams, and questionnaires. Risks associated with this study include shortness of breath, nausea, diarrhea, headaches and dizziness.

This is a global, Phase 3b/4, randomized, open-label, efficacy assessor-blinded, multi-center study that will evaluate upadacitinib compared to dupilumab in adult subjects with moderate to severe AD and inadequate response to dupilumab after at least 6 months of current use. The study consists of a 35-day Screening Period; an 8-week randomized, open-label, efficacy assessor blinded treatment period for all participants (Period 1); a 24-week open-label, efficacy assessor-blinded extension period for all participants who finish Period 1 (Period 2) (total duration of Period 1 and Period 2 is 32 weeks); and a 30-day Follow-up visit.

The study will evaluate the effect of prophylactic intra-operative ventricular tachyarrhythmia ablation (VTA) at the time of left ventricular assist device (LVAD) implantation on post-implant total recurrent VTA events, after accounting for the competing risk of death, from discharge to an average follow-up of 18 months (with a minimum of 9 months) after LVAD implantation.

This is an NIH sponsored trial across the US where patients who have been or will be implanted with cervical vagus nerve stimulation (VNS) are then tested in a variety of ways to determine the activity of the VNS on different organs in their body. This will involve implantation for those who qualify, and then two trips to the University of Minnesota for more extensive testing. The device, implantation and travel are all at no cost.

To undertake the first prospective randomized controlled trial that compares early aortic surgery to aneurysm surveillance.

The purpose of the study is to compare different treatment plans for patients with abnormal aortas. Patients who have an abnormal aorta measuring at least 5.5cm will have surgery to replace the aorta. We do not know, however, whether patients with abnormal aortas that are not quite 5.5cm should have surgery or should be monitored to see if their aorta continues to grow. Therefore, through this registry and interventional study, the hope is to collect more data on which treatment is better for the patient. The interventional group will undergo surgery to repair their abnormal aorta, and the surveillance group will be closely monitored and medically managed per standard of care. Both groups will have data collected from their care and at the end of the study this data will be analyzed. The goal of this study is to determine if performing surgery earlier helps to prevent abnormal aortas below 5.5cm from tearing or bursting.

This study is for subjects that have been diagnosed with lung cancer and the disease has progressed on prior therapy. The purpose of the study is to determine the safety and efficacy of Fingolimod and whether it can aid in treatment against lung cancer tumors. Fingolimod is not FDA approved and is considered an investigational drug. Subjects can expect to be in this study for about 8 months, with routine visits occurring at MUSC.

The purpose of this study is determine the optimal dose, efficacy and safety of an investigational drug (a new drug not yet approved by the U.S. Food and Drug Administration) in adults with Nonadvanced Systemic Mastocytosis. The investigational drug is known as bezuclastinib and will be taken daily orally. Participation in the study is expected to be approximately 3 years.
