Primary Objective: To compare the effect of alirocumab with placebo on the occurrence of cardiovascular (CV) events (composite endpoint of coronary heart disease (CHD) death, non-fatal myocardial infarction (MI), fatal and non-fatal ischemic stroke, unstable angina (UA) requiring hospitalization) in participants who experienced an acute coronary syndrome (ACS) event 4 to 52 weeks prior to randomization and were treated with evidence-based medical and dietary management of dyslipidemia. Secondary Objectives: * To evaluate the effect of alirocumab on secondary endpoints (any CHD event , major CHD event, any CV event, composite of all cause mortality/non-fatal MI/non-fatal ischemic stroke, CHD deaths, CV deaths, all cause mortality). * To evaluate the safety and tolerability of alirocumab. * To evaluate the effect of alirocumab on lipid parameters.
NCT02037555
This is a prospective, multicenter, randomized, double-blind, placebo-controlled study. The purpose of this study is to determine the safety and effectiveness of human-derived antithrombin III (AT-III \[Human\]) supplementation prior to high-risk, non-emergency, cardiac surgery with cardiopulmonary bypass (CPB). A total of 404 adult subjects undergoing CPB who meet the study eligibility criteria were planned to be randomized to receive either AT-III (Human) or placebo.
NCT00807040
People with coronary artery disease (CAD) or people who have had a heart attack may develop a leak in the mitral valve of their heart and may therefore need to undergo surgery to fix the valve. The best way to fix the mitral valve remains undetermined. This study will evaluate whether it is better for people with severe mitral valve leakage to undergo a mitral valve replacement procedure or a mitral valve repair procedure.
NCT01150994
The NIMH s RFA-Suicide Prevention in Emergency Medicine Departments recognizes the emergency department (ED) as an important setting to increase suicide detection and prevention efforts but observes that evidence-based practice guidelines do not exist. In response, we have designed the Emergency Department Safety Assessment and Follow-up Evaluation (ED-SAFE) trial. The ED-SAFE study will be conducted using a quasi-experimental design appropriate for studying systems-based change. The study consists of two components (Screening Outcome \& Intervention Evaluation) and three phases of data collection: Treatment as Usual, Screening Alone, and Intervention. During each phase, 480 suicidal patients (1,440 total) will be enrolled and followed using multiple methods for 12 months. The Screening Outcome Component The Screening Outcome component will use data collected during the Treatment as Usual and Screening Alone phases. Consistent with systems-change principles, when universal screening is incorporated during the Screening Alone phase, it will be completed by the primary nurse as part of routine care. Primarily, it will focus on testing a practical approach to screen ED patients for suicidal ideation and behavior and will assess its impact on suicide detection, process outcomes, and suicide behaviors. Intervention Evaluation Component The Intervention Evaluation component will use data from the Treatment as Usual, Screening Alone, and Intervention Phases. During the Intervention phase, each ED will implement a multi-component, systems-based Intervention called the Safety Assessment and Follow-up Telephone Intervention (SAFTI). The SAFTI will combine elements of: (a) safety planning administered by nursing staff in the ED, and (b) Coping Long Term with Active Suicide Program (CLASP)-ED, a series of up to 7 semi-structured telephone advising calls to the patient and 4 to the significant other over the 12 months after the ED visit. Safety planning will be implemented universally to all suicidal patients, regardless of whether they are ultimately enrolled into the trial, as part of a comprehensive suicide management protocol (e.g., it is a systems-based change). However, for practical and budgetary considerations, the CLASP-ED telephone advising calls will be administered only to participants enrolled into the study. Our overarching hypotheses will be tested using a combination of the Screening Outcome component and the Intervention Evaluation Component. We predict that screening will improve detection of suicidal ideation, and the intervention will enhance the quality of care and reduce suicide outcomes.
NCT01233375
The purpose of this study is to determine whether CO-1.01 is safe and effective for treating metastatic pancreatic cancer that did not respond to gemcitabine.
NCT02132221
This research is being done to better understand how to help patients who are not receiving enough relief from opioid prescription medications for chronic non-cancer pain. Opioids are a group of medications that includes morphine, oxycodone-, hydrocodone-, etc. These medications are also called narcotics. Research has shown that patients not benefiting from their opioid prescription medication often feel better when they stop taking it. However, stopping or reducing pain medications can be a difficult transition. Although they do not have much benefit from their medication, many patients are afraid to stop because they feel these medications are the only things giving them a bit of relief. Different strategies can be used to help patients through the period of tapering and it is not clear which one is best. The investigators will test a specific approach used during regular care in the clinic: cognitive therapy.
NCT02614612

NCT02492737
The purpose of this Phase I, multicenter study is to evaluate the safety, pharmacokinetics, pharmacodynamics and clinical activity of AG-881 in advanced hematologic malignancies that harbor an IDH1 and/or IDH2 mutation
NCT01666275
Metabolomics is the study of metabolic pathways and the unique biochemical molecules which result from the regulatory response to physiological stressors, disease processes, or drug therapy. By measuring changes in metabolite concentrations, the range of biochemical effects and therapeutic intervention can be determined. Aspirin exacerbated respiratory disease (AERD) is a chronic inflammatory disease characterized by chronic rhinosinusitis, nasal polyposis, asthma, and airway reactivity to aspirin and/or other nonsteroidal anti-inflammatory drugs (NSAIDs). This reaction to aspirin during challenge/desensitization is equivalent to an allergic drug reaction however we are able to evaluate these specific reactions in a controlled, clinical environment. This population of patients undergoing aspirin desensitization is ideal for studying metabolomics as serial blood sampling can be performed in patients before, during a reaction, and after aspirin desensitization, thereby allowing each patient to serve as his or her own biological control. The investigator hopes that this study of metabolomics will allow for better methods of identifying anaphylaxis in the future.
NCT01285960
The purpose of this study is to evaluate the safety and ablation efficacy of the ExAblate UF V2 System when treating symptomatic uterine fibroids. The ExAblate System is a medical device that involves a focused ultrasound system and an MRI scanner. ExAblate delivers a pulse of focused ultrasound energy, or sonication, to the targeted tissue. In this particular study, the targeted tissue is uterine fibroids. Each sonication is used to heat small spots in the fibroid much like a magnifying glass can be used to focus light to heat a spot. The heat created kills a portion of the fibroid with the goal of decreasing or eliminating uterine fibroid-related symptoms. Repeated sonications are performed until the entire fibroid is treated or the treated volume is determined to be appropriate. The ExAblate system is commercially approved in the United States to treat symptomatic uterine fibroids. The ExAblate UF V2 System is an experimental device and is being investigated in this study. While similar to the commercial system, the ExAblate UF V2 device includes the following major changes, among others, which are intended to improve device performance and safety: * Up and down movement of the ultrasound transducer, in an attempt to improve fibroid treatment by moving the ultrasound focal point within the targeted fibroid. * Ultrasound energy can be turned off for a specific area in an attempt to minimize amount of energy passing through sensitive areas of the body.
NCT03579654
This study will evaluate the safety and efficacy of a prostate cancer vaccine named Proscavax (Prostate-specific antigen(PSA) / Interleukin-2(IL-2) / Granulocyte-macrophage colony-stimulating factor(GM-CSF)) in patients with localized prostate cancer. The goal of the study is to determine if vaccine administration results in a change in the rate of prostate cancer progression when compared to a no-treatment control group of active surveillance patients. The researchers are interested in evaluating the proportion of participants with prostate cancer progression at 2 years following administration of Proscavax or active surveillance, the effect of the vaccine on prostate-specific antigen (PSA) doubling time and the assessment of adverse events in these patients. Eligible patients in this study will include men who are 18 years and older and who have a previously untreated early stage prostate cancer regardless of the date of diagnosis.
NCT00404248
RATIONALE: Drugs used in chemotherapy, such as tetra-O-methyl nordihydroguaiaretic acid (EM-1421), work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. PURPOSE: This phase I/II trial is studying the side effects and best dose of EM-1421 and to see how well it works in treating patients with recurrent high-grade glioma.
NCT01639482
