There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The main goal of this study is to characterize presentation, clinical course, and long-term outcomes of myocarditis temporally associated with administration of mRNA-1273 (SPIKEVAX) COVID-19 vaccine.
This is an add-on substudy to an already-approved clinical trial "A Multi-Site Phase 3 Study of MDMA-Assisted Psychotherapy for PTSD" (ClinicalTrials.gov Identifier: NCT03537014) which is to be a phase 3 clinical trial studying the efficacy of MDMA-Assisted Psychotherapy for Post Traumatic Stress Disorder. The parent study has been approved by Copernicus Group IRB and is being run by the MAPS Public Benefit Corporation, and is a randomized controlled trial comparing the clinical efficacy of MDMA-assisted psychotherapy to Placebo-assisted psychotherapy. The parent study will recruit participants with Post Traumatic Stress Disorder and involves 20 total study visits over the course of 18 weeks including 3 preparatory psychotherapy visits plus 3 separate treatment sessions involving psychotherapy plus the administration of MDMA vs. placebo and 3 follow up psychotherapy visits after each treatment session. This substudy adds on the collection of saliva in a salivary DNA collection kit at baseline and after treatment to the parent study clinical trail so as to assess whether the MDMA-Assisted Psychotherapy exerts influence on the epigenetic regulation of stress-associated genes as assessed in the salivary epithelial and white blood cells of the research participants. We aim to further assess whether any such changes are correlated with improvements in PTSD symptoms.
The main purpose of this study is to determine effect of orforglipron capsule formulation on the amount of digoxin, rosuvastatin, acetaminophen, midazolam, and simvastatin (each given alone and together with orforglipron) that enters the bloodstream and how long it takes the body to eliminate them when administered orally in healthy overweight and obese participants. In addition, the effect of the orforglipron tablet on the amount of simvastatin that enters the bloodstream and how long it takes the body to eliminate it will be evaluated. The study will also assess the effect of sodium bicarbonate when administered alone with simvastatin versus orforglipron capsule containing sodium bicarbonate administered with simvastatin. The safety and tolerability of orforglipron and information about any side effects experienced will be collected. Study will be conducted in two parts, with part 1 and 2 lasting up to approximately 23 and 24 weeks each, including the screening period.
Knee osteoarthritis is an extremely common and debilitating condition, more common in women, with an estimated global prevalence of 16%, and as high as 50% by the age of 80. Current management of knee osteoarthritis (OA) revolves around conservative treatments- biomechanical interventions, intra-articular injections, exercise, self-management and education, oral or topical medications, strength training, and weight management - or surgical management. For injection therapies, corticosteroids remain the standard of care; approximately 84% of sports medicine physicians perform these knee injections at least monthly, reporting a median range of 11-20 injections per month. Multiple detrimental effects of corticosteroid injections are well-known, including alterations of the hypothalamic-pituitary-adrenal axis, blood glucose levels, bone turnover, inflammatory response, blood pressure, and psychologic well-being. Thus, alternative therapies are of the utmost importance. Platelet-Rich Plasma (PRP) is an injectable preparation of a patient's blood that can be used for numerous conditions and has received significant attention over the past several years for its potential application for the treatment of pain and functional impairment due to knee OA. Systematic reviews of randomized-controlled trials have demonstrated equivalent-to-superior treatment outcomes associated with the use of intra-articular PRP compared to placebo, hyaluronic acid, and corticosteroid. Furthermore, use of intra-articular PRP is associated with a very low rate of adverse events and is likely safer than injectable corticosteroids. Concerns that have limited a wider use of PRP include two main concerns - an uncertainty regarding the current evidence base due to study-related bias, heterogeneity, and lack of reporting standards; and second, more importantly, the main issue remains high cost.
This retrospective study will evaluate the coronary angiograms of approximately 100 patients who have undergone invasive angiography and fractional flow reserve (FFR). DICOM files of the angiograms will be analyzed on a secure computer within the cardiac catheterization laboratory using the AutocathFFR software to assess if invasive FFR measurements and automated computer analysis of FFR measurements correlate. AutocathFFR measurement per lesion will be compared to the gold standard, invasive FFR value, where an FFR ≤ 0.80 will be considered "positive", while an FFR > 0.8 will be considered "negative". The AutocathFFR value will be compared to the invasive FFR measurements. The sensitivity and specificity of the AutocathFFR will be calculated, as well as the AutocathFFR accuracy, positive predictive value and negative predictive value per lesion. Device success will be calculated as the ratio of completed versus initiated AutocathFFR index calculations. Usability of the AutocathFFR software will be evaluated using dedicated questionnaires to be completed by the user (cardiologists).
The primary objective of this study is to establish an IL-6 concentration cutoff and optimal time point(s) for using Symphony IL-6 that predict 28-day mortality in patients who are admitted or are intended to be admitted to the intensive care unit (ICU) diagnosed with sepsis or septic shock.
Chronic health conditions (CHC) commonly share the challenge of impaired health-related quality of life, negatively impacting the lives of millions of people in the United States. Long term effects for living with a chronic health condition are likely to include poor self-management behaviors, which are related to avoidance of disease related thoughts and feelings (e.g., health anxiety) and can be addressed directly with psychosocial interventions. With the focus on fostering values driven and meaningful behavior while accepting thoughts and feelings, ACT may prove to be a particularly effective approach for individuals coping with the challenging symptoms and effects of having a chronic health condition. Previous web-based ACT interventions for CHCs have focused on building ACT skills for a narrow subset of CHCs (e.g., breast cancer, diabetes, tinnitus). While there is added benefit for a self-help program for populations with specific stressors or conditions, there is also a high prevalence of comorbidity in CHCs, shared challenges in illness management and coping, and clear evidence that ACT works effectively across CHCs to improve quality of life. Thus, our goal of this research project is to evaluate a new 6 session, online, self-guided ACT program for adults with chronic health conditions broadly to improve their quality of life and wellbeing through a randomized controlled trial. The specific aims are: 1. To evaluate the feasibility of an initial prototype of ACT program for adults with CHC's as indicated by recruitment, retention, and adherence rates. 2. To evaluate the acceptability as indicated by self-reported program satisfaction and qualitative feedback following the course completion. 3. To identify ways to further refine the program based on participant self-reported satisfaction with sessions and open-ended text-based feedback. 4. To test the efficacy of the program on improving quality of life among adults with CHC's.
The purpose of this study is to understand the safety and effects of a combined influenza and COVID-19 vaccine. This combined vaccine is compared to separate vaccines for the protection against influenza and SARS-CoV-2. Influenza and COVID-19 are diseases that can spread easily from one person to another and cause body aches, fever, cough, and other symptoms. Giving both influenza and COVID-19 vaccines together against influenza and SARS-CoV-2 could provide great benefits to both patients and caregivers in terms of simple and easy care. Around 8550 participants will be assigned into 1 of 8 vaccination groups (Group A, B, C, D, E, F, G or H) by chance. Cohort 1: Approximately 450 participants will be assigned by chance to one of the following: - Group A:Influenza and COVID-19 combination A vaccine, given at the same time in one arm and placebo (an injection consisting of just salt water and no medicines in it) in the opposite arm. - Group B: COVID-19 vaccine, given at the same time to one arm and licensed influenza vaccine in the opposite arm. Cohort 2: Approximately 4500 participants will be assigned by chance to one of the following: - Group C: Influenza and COVID-19 combination B vaccine, given at the same time in one arm and placebo in the opposite arm. - Group D: COVID-19 vaccine, given at the same time in one arm and licenced influenza vaccine in the opposite arm. Cohort 3: Approximately 3600 participants will be assigned by chance to one of the following: - Group E: Influenza and COVID-19 combination B vaccine. - Group F: COVID-19 vaccine. - Group G: Licenced influenza vaccine. - Group H: Investigational influenza vaccine. All participants in cohort 1 and cohort 2 will receive 2 injections and participants in cohort 3 will receive 1 injection as per their assigned study group at Visit 1. The participants will be followed for about 6 months. During this time, researchers will assess safety and the body's reaction to the vaccination over approximately 6 months. This will help understand if the study medicine is safe.
The purpose of this extension study is to continue to follow the participants who completed the CLVer RCT for up to 3 additional years. The goal for Cohort A is to evaluate the longer-term effects of verapamil on preservation of β-cell function as measured by C-peptide levels obtained during a mixed meal tolerance test (MMTT). For both Cohorts A and B, the goal is to determine if the high degree of glycemic control achieved during CLVer with HCL can be maintained once the intensive engagement of the study team is discontinued. At the completion of the RCT, study treatments end. Thus, during the extension study, diabetes management is performed as part of usual care and there is no study treatment.
