Epithelial ovarian cancer (EOC) is the 5th leading cause of cancer death in women in the U.S. African-American (AA) women have the lowest survival of any racial/ethnic group,1 yet little is known about factors affecting survival among AAs. The African American Cancer Epidemiology Study (AACES) is a multi-site epidemiologic study of AA women in diverse geographic regions. AACES has enrolled an unprecedented number of AA participants during a previous funding period, 593 AA women with invasive EOC and 752 controls, making AACES the largest study of ovarian cancer in AA women to date. Prior to AACES, no epidemiologic study of ovarian cancer had enrolled more than 150 AA cases and 150 AA controls. Due to comprehensive data collection, pathology assessment and length of follow-up, AACES is uniquely positioned to evaluate factors influencing the survival of EOC in AA women. The causes of the poor outcomes in AA women are likely multifactorial and need to be examined from multiple levels, including factors affecting both the neighborhood social environment and individual level factors.

The overarching goal of the Master Protocol is to find effective strategies for inpatient management of patients with COVID-19. Therapeutic goals for patients hospitalized for COVID-19 include hastening recovery and preventing progression to critical illness, multiorgan failure, or death. Our objective is to determine whether modulating the host tissue response with agents targeting the RAAS improves clinical outcomes among patients with COVID-19.
Potential agents to investigate on this platform include TXA127 and TRV027. Both have potential beneficial effects on the RAAS system in COVID-19. We postulate that SARS-CoV-2 spike protein interaction with the ACE2 receptor leads to unchecked activity of AngII, and RAAS-targeting therapies will counterbalance pathologic RAAS effects. We will evaluate the efficacy of TXA127 and TRV027 in restoring RAAS balance.

The purpose of this research is to find out if a drug called ganciclovir can prevent cytomegalovirus (CMV) reactivation, in which the virus wakes up from an inactive state, in patients with respiratory failure associated with severe sepsis. In order for you to take part in this study, we verified that you also have previously had an infection with a virus called Cytomegalovirus (CMV). Ganciclovir is an FDA approved drug that has been widely used for the prevention and treatment of CMV in patients with weakened immune systems. A total of 482 patients will be enrolled in this study at sites throughout the US.

The purpose of this study is to use magnetic resonance imaging (MRI) to take images of a participant's brain, and then apply an investigational way of processing the image, called Individualized Network-based Single-frame Coactivation Pattern Estimation ("INSCAPE") to measure participant's brain activity. This method uses a computer program to understand which parts of the brain communicate with each other and creates a map of the brain areas that are connected.

Participants being recruited in this study will include people planning to receive Transcranial Magnetic Stimulation ("TMS") for Major Depressive Disorder ("MDD"). Healthy participants are also being recruited. Images taken of depressed participants' brains will be compared to images of non-depressed participants' brains. Participation in this study will require three visits in which you will undergo MRI scans. The interval between each visits is about 3 weeks. Depressed participants will also complete mood assessments at several different intervals while they are receiving TMS for depression.

During each visit, MRI scans will require about 30 minutes of time in total. During the MRI scan, participants will need to stay still, relax, and keep eyes open in the scanner.

The protocol aims to improve standard of care, by ensuring an agile research infrastructure, with an ability to rapidly assess interventions during epidemic transmission of one or more respiratory pathogens adversely affecting public health.

Trials within this protocol can be adaptive, will be randomized, and will have superiority as the primary objective. Comparisons in the trials may be between an unlicensed agent to a blinded placebo plus standard of care (SOC), between an approved off-label agent to a blinded placebo plus SOC, among several active interventions (blinded or non-blinded; i.e., a comparative effectiveness study), or among different treatment strategies.

The main purpose of the study is to find out if patients treated with remibrutinib may experience fewer Multiple Sclerosis relapses (also called clinical attacks, exacerbations or flare ups) than patients treated with teriflunomide (also known as Aubagio). Teriflunomide is an approved medication for the treatment of relapsing MS. This clinical study will have two parts. The first part is the masked part in which neither you nor your doctor know if you receive remibrutinib or teriflunomide and will last up for a maximum of up to 30 months (~2.5 years). This is followed by an Extension Part which will have treatment and safety follow up periods; during the treatment period remibrutinib treatment is provided to all participants who had completed core part of study for a maximum of up to 5 years.

This study is part of what is called a platform study. This platform study, called the "PRACTICAL" study is designed so that various interventions can be evaluated at the same time against standard therapy. This allows researchers to compare these newer interventions to each other as well as to the established usual practice and helps them explore different ways to potentially improve the management of lung injury. Within the platform study there are various different sub-studies that have their own interventions and procedures. This domain sub-study is the "Mechanical Ventilation Study" and it is a multi-centre, randomized, open-label trial that will evaluate multiple ventilation strategies in comparison to conventional lung-protective ventilation in patients with acute hypoxemic respiratory failure (AHRF). This domain will enroll perpetually, as interventions are added, continued, or discontinued. Researchers for this study are looking for different types of ventilation strategies (ways that the ventilators control settings can be adjusted) that may be the most helpful for people in their recovery, while also reducing lung damage caused by the ventilator.

This will be a 26-week, prospective, multicenter, randomized, double-blind, placebo-controlled safety and efficacy study of udenafil 87.5 mg tablets versus placebo (both taken twice daily in adolescent subjects who have had the Fontan procedure. The primary efficacy endpoint will be change from baseline at 26 weeks in peak minute oxygen consumption [VO2] (mL/kg/min).

The purpose of this study is to better understand how certain parts of the immune system may explain differences seen in the severity of Multiple Sclerosis. This will require one visit, typically less than an hour. We will collect some information about the subject's past medical history including the severity of their multiple sclerosis, and their medications as well as collect a sample of blood. This will also include a measure of genetics related to the immune system. Blood will also be stored for future research.

This study is a multicenter, randomized, double-blinded, placebo-controlled trial to evaluate the safety and efficacy of ExoFlo for the treatment of moderate-to-severe ARDS (Acute Respiratory Distress Syndrome). The purpose of this study is to research and evaluate the safety and efficacy of intravenous (IV) administration of bone marrow mesenchymal stem cell derived extracellular vesicles, ExoFlo, as treatment for Moderate-to-Severe ARDS. Bone Marrow Mesenchymal Stem Cell (bmMSC)-Derived Extracellular Vesicles is an investigational drug created from human bone marrow being studied for the treatment of moderate-to-severe ARDS. This is a research study that will involve monitoring oxygen and inflammation levels after taking the investigational product and assessing the safety of the investigational product. The experimental treatment is a biologic product called Bone Marrow Mesenchymal Stem Cell (bmMSC)-Derived Extracellular Vesicles Allograft Product ExoFlo, which is purified from the bone marrow of a healthy well-screened individual. Participants will receive either 15mL of the investigational product with 85 mL of normal saline or 100 mL of normal saline only (placebo). The expected duration of participation in the study is a maximum of 61 days, which includes 1-day screening prior to treatment and 60 days following the first treatment.
