Since its launch in 2004, the overarching aim of the Alzheimer's Disease Neuroimaging Initiative (ADNI) has been realized in informing the design of therapeutic trials in AD. ADNI3 continues the previously funded ADNI-1, ADNI-GO, and ADNI-2 studies that have been combined public/private collaborations between academia and industry to determine the relationships between the clinical, cognitive, imaging, genetic and biochemical biomarker characteristics of the entire spectrum of Alzheimer's disease (AD). The overall goal of the study is to continue to discover, optimize, standardize, and validate clinical trial measures and biomarkers used in AD research.

This study is being conducted to determine if losartan, an angiotensin receptor blocker (ARB), is safe and effective in the treatment of posttraumatic stress disorder (PTSD) symptoms. The study is also intended to determine if certain genetic markers are useful in predicting PTSD symptom reduction with losartan. Approximately 160 subjects with chronic PTSD ages 18-65 will participate in this study across five sites. Subjects will be assigned by chance to take either flexibly dosed losartan (up to a maximum dosage of 100 mg) or placebo (which resembles the study drug but has no active ingredients), once a day for 10 weeks. Furthermore, it is hypothesized that CC homozygotes for rs4311 SNP in the ACE gene will have a superior response to losartan on PTSD symptoms compared to T carriers.

HIV-infected individuals treated with antiretroviral medications are living longer, but have an increased risk of heart disease when compared to non-HIV-infected individuals. A hormone called aldosterone, which regulates blood pressure and sodium balance, is elevated in the HIV population in association with with increased belly fat and altered glucose metabolism. Elevations in aldosterone hormone may also be associated with abnormal blood flow, inflammation, and coronary plaque in the heart. This study is being conducted to evaluate whether therapies to reduce the actions of aldosterone may decrease the burden and progression of heart disease in the HIV population.

The purpose of the Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation (COAPT) Trial is to confirm the safety and effectiveness of the MitraClip System for the treatment of moderate-to-severe or severe functional mitral regurgitation (FMR) in Symptomatic Heart Failure Subjects who are treated per standard of care and who have been determined by the site's local heart team as not appropriate for mitral valve surgery. This randomized controlled trial will provide the opportunity to strengthen or add labeling claims regarding safety and clinical benefits of the MitraClip System for symptomatic heart failure patients with moderate-to-severe or severe functional mitral regurgitation. Approximately 610 subjects will be randomized at up to 100 investigational sites with approximately 305 subjects targeted to receive the study device. COAPT study completed recruiting subjects in June 2017. As part of the COAPT trial, a subset of patients will be registered in the cardiopulmonary exercise (CPX) sub-study. The objective of this sub-study is to evaluate the exercise responses in a sub-cohort of COAPT subjects who receive MitraClip device (Device group) compared to the Control group who do not receive MitraClip device. (Note: the CPX Sub-study subjects will contribute to the analyses of the COAPT primary and secondary endpoints) As an extension of the COAPT RCT trial, COAPT CAS study will be conducted after COAPT enrollment is complete under the same investigational device exemption (IDE(G120024)). The objective of this study is to evaluate the MitraClip® NT System for the treatment of clinically significant functional mitral regurgitation (FMR) in symptomatic heart failure subjects who are treated per standard of care and who have been determined by the site's local heart team as not appropriate for mitral valve surgery. The anticipated study Primary Completion date is July 2018 and the Study Completion Date is July 2024. COAPT CAS is presently recruiting subjects.

This partially randomized phase II/III trial studies how well, in combination with surgery, cisplatin and combination chemotherapy works in treating children and young adults with hepatoblastoma or hepatocellular carcinoma. Drugs used in chemotherapy, such as cisplatin, doxorubicin, fluorouracil, vincristine sulfate, carboplatin, etoposide, irinotecan, sorafenib, gemcitabine and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving combination chemotherapy may kill more tumor cells than one type of chemotherapy alone.

This research study is a Phase I clinical trial. Phase I clinical trials test the safety of an investigational intervention. Phase I studies also try to define the appropriate dose of the investigational therapy to use for further studies. "Investigational" means that the intervention is still being studied and that research doctors are trying to find out more about it. Retroperitoneal sarcomas are soft tissue tumors located at the far back of the abdomen. Typically, patients with retroperitoneal sarcomas either have surgery for the removal of their tumors alone, or have their tumors removed, followed by standard radiation therapy, or have pre-operative radiation followed by surgery. When conventional radiation therapy is delivered after surgery, it can damage normal tissue. In this study, you will undergo proton beam radiation therapy or IMRT before undergoing surgery for the removal of your tumor. Proton radiation and IMRT are FDA approved radiation delivery systems. Protons are tiny particles with positive charge that can be controlled to travel a certain distance and stop inside the body. In theory, this allows better control of where the radiation dose is delivered as compared to photons. Since proton radiation is more targeted, it may help to reduce unwanted side effects from radiation. In this study, a standard dose of radiation will be given to the majority of the tumor, while a simultaneously integrated boost of additional radiation will be given to certain areas of the tumor identified as higher risk. This means that a higher radiation dose will be given to the higher risk areas of the tumor. The purpose of this study is to determine the highest dose of radiation therapy with protons or IMRT that can be delivered safely in patients with retroperitoneal sarcomas and the effectiveness of proton beam radiation therapy as an intervention for patients with retroperitoneal sarcomas.

The study will be conducted in compliance with the International Council for Harmonisation (ICH) of Technical Requirements for Registration of Pharmaceuticals for Human Use/Good Clinical Practice (GCP) and applicable regulatory requirements. This is a randomized, open-label, parallel-group, multi-center trial in adult subjects with Relapsed or refractory (R/R) aggressive Non-Hodgkin lymphoma (NHL) to compare safety and efficacy between the standard of care (SOC) strategy versus JCAR017 (also known as lisocabtagene maraleucel or liso-cel). Subjects will be randomized to either receive SOC (Arm A) or to receive JCAR017 (Arm B). All subjects randomized to Arm A will receive Standard of care (SOC) salvage therapy (R-DHAP, RICE or R-GDP) as per physician's choice before proceeding to High dose chemotherapy (HDCT) and Hematopoietic stem cell transplant (HSCT). Subjects from Arm A may be allowed to cross over and receive JCAR017 upon confirmation of an EFS event. Subjects randomized to Arm B will receive Lymphodepleting (LD) chemotherapy followed by JCAR017 infusion.

Cardiac steatosis is increased among individuals with HIV, and may predispose to cardiac mechanical dysfunction and subsequent heart failure. The pathogenesis and treatment of cardiac steatosis is not well understood. The investigators have previously shown that perturbed growth hormone (GH) secretion in HIV contributes to ectopic fat accumulation in the viscera and the liver. Moreover, the investigators have found that augmentation of endogenous GH secretion with the FDA-approved medication tesamorelin reduces visceral and hepatic fat. In this longitudinal observational study, the investigators will examine patients with HIV and abdominal fat accumulation who either plan or do not plan to initiate tesamorelin prescribed clinically. The investigators hypothesize that blunted GH secretion in HIV is associated with cardiac steatosis. The investigators also hypothesize that use of tesamorelin for 6 months is associated with a reduction in intramyocardial fat and preserved cardiac function.
