NCT03884608
The purpose of this registry is to prospectively assess outcomes of device-treated ventricular tachyarrhythmias and all-cause mortality in non-ischemic cardiomyopathy patients indicated for ICD or CRT-D implantation for the primary prevention of sudden cardiac death. Differences in outcomes will be evaluated by sex and by device type.
NCT03406611
Homocystinuria caused by Cystathionine Beta-Synthase (CBS) Deficiency is a rare autosomal-recessive metabolic condition characterized by an excess of homocysteine (Hcy) in the plasma, tissues and urine. It is due to reduced or absent activity of the CBS enzyme, and is also known as classical homocystinuria. The symptoms associated with homocystinuria are variable in severity and time of onset across patients. Some affected individuals may have mild signs of the disorder; others may have multi-systemic involvement including potentially life-threatening complications. Homocystinuria can affect many different organ systems of the body; the four most commonly involved are the eyes, central nervous system, skeleton, and the vascular system. The current approaches to treatment of homocystinuria patients include a highly restrictive diet and use of dietary supplements. Lifetime compliance with this diet is poor. Pegtibatinase (TVT-058) represents a novel therapeutic approach that incorporates the use of a modified version of the native, human CBS (hCBS) enzyme. The goal of treatment is to introduce the CBS enzyme into circulation, resulting in reduced Hcy levels, increased cystathionine (Cth) and cysteine (Cys) levels.
NCT01231971
The purpose of this study is to build upon the information obtained in the original Alzheimer's Disease Neuroimaging Initiative (ADNI1) and ADNI-GO (Grand Opportunity; a study funded through an NIH grant under the American Recovery and Reinvestment Act), to examine how brain imaging technology can be used with other tests to measure the progression of mild cognitive impairment (MCI) and early Alzheimer's disease (AD). ADNI2 seeks to inform the neuroscience of AD. This information will aid in the early detection of AD, and in measuring the effectiveness of treatments in future clinical trials.
NCT04724759
This study aims is to evaluate the effect of opioid free total intravenous anesthesia on postoperative quality of recovery in patients undergoing oral and maxillofacial surgery (OMF) temporomandibular joint (TMJ) surgery.
NCT03238755
In this study, investigators plan to test whether statins can preserve and/or improve diastolic function among asymptomatic persons with HIV who are on anti-retroviral therapy. Both myocardial fibrosis and myocardial steatosis are thought to contribute to diastolic dysfunction and eventually overt heart failure in HIV. HIV-positive participants will undergo cardiac MRI/MRS imaging studies for the evaluation of myocardial fibrosis and myocardial steatosis prior to initiation of statin or placebo therapy and then two years after initiation of statin or placebo therapy. Traditional markers of cardiovascular (CVD) risk, systemic immune activation/ inflammation, HIV-specific parameters (i.e. CD4 count), and markers of myocardial stretch/injury will be assessed in relation to cardiac MRI/MRS outcomes.
NCT05048186
This is a retrospective observational survey study. We will survey a sample of adult parents or legal guardians who have a child who has been diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) and who discussed ADHD treatment options for their child with a health care provider within the last 2 years. The main goal is to gather evidence of the validity and reliability of the Shared Decision Making Process scale. Secondary goal is to gather evidence on the quality of decisions parents make about their children with ADHD. A third goal is to assess the impact of a Decision Aid on participant knowledge of ADHD treatment options. Participants will be randomized to one of two arms: participants in the intervention arm will review a Decision Aid (patient educational tool) partway through the survey and those in the control arm will not receive any educational materials. All participants will complete survey that includes the Shared Decision Making process survey along with a few other measures. A subset of respondents will also complete a retest survey about two weeks after the initial survey.
NCT06698848
Subanesthetic dose of intravenous ketamine (KET) has been found to be highly effective in rapid treatment depression and associated suicidality but its exact mechanism of remains uncertain. This study will use a novel approach to elucidate KET's effects on the molecular/ gene expression pathways in living neurons obtained from the olfactory epithelium and correlate the changes to rapid improvement in depression via changes in the brain connectome. The study will identify the molecular targets and pathways involved in KET'S mechanism of rapid clinical action and pave the way for development of novel, more efficacious, and safer therapeutic agents.
NCT02409680
Available data suggest that low dose aspirin may be a safe, widely available and inexpensive intervention that may significantly reduce the risk of preterm birth. However, this possibility needs to be proven in a properly designed randomized controlled trial (RCT) with preterm birth as the primary outcome. Such a clinical trial in a racially, ethnically and geographically diverse population could best be accomplished by the established infrastructure of the Global Network for Women's and Children's Health Research (GN).
NCT02457936
Depression one of the leading causes of disability worldwide. Individuals suffering from depression typically exhibit impairments in various mental abilities, such as the ability to effectively direct and control attention and the ability to switch between thinking about different things and concepts (commonly referred to as "cognitive flexibility"). Mindfulness meditation training is a technique which involves focusing one's awareness on the present moment, while calmly acknowledging and accepting one's feelings, thoughts, and bodily sensations. It has been well documented to improve depressive symptoms and prevent recurrence of depressive episodes, yet little is known about how mindfulness does so and what are the underlying mental mechanisms involved. Here the investigators propose to examine the efficacy of an 8-week mindfulness training program in improving the ability to direct and control attention, as well as in cognitive flexibility. Individuals diagnosed with recurrent depression will undergo an 8-week mindfulness training program. Participants' depressive symptoms as well as their performance on measures of attention and cognitive flexibility will be examined. Participants will be assigned to mindfulness training or a wait-list control group. Half of the participants will be examined before and after the mindfulness training program and the other half will be tested 8-weeks apart and then begin their training.
NCT06116110
This is an observational long-term follow-up (LTFU) study for subjects who previously received zamtocabtagene autoleucel, known as MB-CART2019.1.
NCT03582085
The investigators are doing this research study to explore whether the bacillus Calmette-Guérin (BCG) vaccine can be an effective treatment for fibromyalgia. The researchers believe that the BCG vaccine can benefit people with fibromyalgia by increasing immune signaling molecules, called cytokines. The Faustman Immunobiology Laboratory has previously studied BCG in long term type 1 diabetics, and found that BCG vaccinations showed a short and small pancreas effect of restored insulin secretion. Eligible volunteers will be vaccinated with BCG in repeat fashion over a period of three years or receive placebo treatment. The investigators hypothesize that these repeat injections of BCG will reduce symptom severity by increasing immune signaling cytokines.
NCT03393520
This study will be conducted to evaluate the efficacy, safety, and tolerability of AVP-786 compared to placebo, for the treatment of agitation in participants with dementia of the Alzheimer's type.
NCT03552276
A long term study to demonstrate the safety of Tildrakizumab in Subjects with Psoriatic Arthritis who Have Previously Completed Study with Tildrakizumab
NCT05004181
This trial consisted of three parts, Part A, Part B, and Part C, and evaluated the safety and immunogenicity of a third (booster) injection of the multivalent vaccine BNT162b2 (B.1.1.7 + B.1.617.2), and the safety and immunogenicity of a third booster injection of the monovalent vaccine BNT162b2 (B.1.617.2) or BNT162b2 (B.1.1.7), in participants who had received two doses of the parent vaccine BNT162b2 at 30 µg, at least 6 months after the second dose of BNT162b2. It also evaluated the safety and immunogenicity of a three-dose regimen of BNT162b2 (B.1.1.7 + B.1.617.2) in participants who had not received prior Coronavirus Disease 2019 (COVID-19) vaccination. In addition, the safety and immunogenicity of BNT162b2 (B.1.1.529.1) or BNT162b2 given as a third or fourth vaccine dose to RNA COVID-19 vaccine-experienced participants with history of SARS-CoV-2 Omicron variant infection was evaluated and contrasted with the natural immune response reached after infection with the SARS-CoV-2 Omicron variant in RNA COVID-19 vaccine-experienced participants.
NCT04754022
TRICS-IV is an international, multi-centre, open-label randomized controlled trial of two commonly used transfusion strategies in moderate to high risk patients who are 65 years of age or younger undergoing cardiac surgery on cardiopulmonary bypass, using a superiority trial design.
NCT03876457
SELECT 2 evaluates the efficacy and safety of endovascular thrombectomy compared to medical management alone in acute ischemic stroke patients due to a large vessel occlusion in the distal ICA and MCA M1 who have large core on either CT (ASPECTS: 3-5) or advanced perfusion imaging (\[rCBF\<30%\] on CTP or \[ADC\<620\] on MRI: ≥50cc) or both and are treated within 0-24 hours from last known well.
NCT01638000
The purpose of the study was to assess the efficacy, safety and tolerability of mirabegron 50 mg versus (vs) solifenacin 5 mg in the treatment of patients with OAB who were dissatisfied with their treatment due to lack of efficacy.
NCT04919499
This study is open to adults with diabetic macular ischemia who have received laser treatment. The main purpose of this study is to find out whether people with diabetic macular ischemia can tolerate a medicine called BI 765128. In this study, BI 765128 is given to people for the first time. The study has 2 parts. Part A tests 3 doses of BI 765128. Participants get either a low, medium or high dose of BI 765128 as a single injection into the eye. If participants tolerate it well, the highest dose will be used in part B. In part B, participants are put into 2 groups randomly, which means by chance. 1 group gets BI 765128 as injection into the eye. The other group gets sham injections. A sham injection means that it is not a real injection and contains no medicine. Participants cannot tell whether they get the real injection or a sham injection. In this part, participants receive study treatment once every month for 3 months. Participants in part A are in the study for about 4 months and visit the study site about 8 times. Participants in part B are in the study for about 5 months and visit the study site about 7 times. The doctors regularly check participants' health and take note of any unwanted effects.
NCT06695832
Staphylococcus aureus bacteraemia is a frequent and life-threatening infection, despite current standard antibiotic monotherapy. This study aims to clarify the role of fosfomycin as an adjunctive therapy for improving outcomes in patients with this serious infection. Two clinical trials suggested that adjunctive fosfomycin therapy might offer a clinical benefit in certain cases, but the results are inconclusive. We aim to analyse pooled data from these trials in order to identify subgroups of patients that might benefit most from this therapy.
NCT06352619
Several clinical trials have produced variable conclusions regarding the effects of intensive blood pressure (BP) lowering in post-EVT acute ischaemic stroke (AIS) patients. Although two trials indicate harm from very intensive target-based treatment (SBP \<130 mmHg), the others neutral effects in the SBP range 140-160 mmHg. The ENCHANTED3/MT domain of the ACT-GLOBAL platform trial aims to test different approaches to the treatment of elevated SBP in post-EVT AIS patients to find an optimal BP management strategy. ENCHANTED3/MT will randomize (1:1:1) up to 2,000 patients with SBP ≥150 mmHg post-EVT to conservative (no or minimal SBP reduction by 5-10mmHg or a target of 175-180mmHg if very-high baseline SBP \[≥180mmHg\]), moderate (SBP reduction by 10-20mmHg or a target of 160 ± 5, whichever is higher; no control if low-high baseline SBP \[150-160mmHg\]), or intensive (SBP reduction by 30-50mmHg or a target of 140±5 mmHg, whichever is higher) BP management.
