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 purpose of this study is to evaluate the efficacy and safety of vutrisiran (ALN-TTRSC02) in participants with hereditary transthyretin amyloidosis (hATTR amyloidosis). Participants will receive vutrisiran subcutaneous (SC) injection once every 3 months (q3M) or the reference comparator patisiran intravenous (IV) injection once every 3 weeks (q3w) during the 18 month Treatment Period. This study will use the placebo arm of the APOLLO study (NCT01960348) as an external comparator for the primary and most other efficacy endpoints during the 18 Month Treatment Period. Following the 18 Month Treatment Period, all participants will be randomized to receive vutrisiran SC injection once every 6 months (q6M) or q3M in the Randomized Treatment Extension (RTE) Period.
This study evaluates the feasibility and the potential positive health impacts of a novel "health education theater," which will task participants of a health education program to create an original 10-minute theater that is required to use the health guidelines about physical activity and diet/nutrition. The outcomes include the changes in (a) knowledge about these guidelines, (b) compliance to these guidelines, (c) health related quality of life, and (d) self-perception well-being measures such as self-esteem and self-efficacy.
This project evaluates the effectiveness of an evidence-based intervention (HEALTH) to prevent weight gain and promote weight loss when disseminated and implemented in real-world settings, through Parents as Teachers. To enhance the impact of HEALTH, the study also evaluates implementation outcomes from the training curriculum (implementation strategy) and external validity when HEALTH is implemented within this national home visiting organization. This partnership has potential for significant impact on obesity and chronic diseases such as cardiovascular disease and diabetes.
This study will be done in people living with HIV to see if an investigational vaccine made from a person's own white blood cells is safe and tolerated. This study will also look at the body's immune response to the vaccine and evaluate four different methods of making the vaccine to see which method may result in better immune responses.
Succinic Semialdehyde Dehydrogenase deficiency (SSADHD) is a rare autosomal recessive disease that interferes with the catabolism of the major inhibitory neurotransmitter gamma-amino butyric acid (GABA) and furthermore leads to accumulation of various potential toxic metabolites, most prominently gamma hydroxybutyric acid (GHB). Current research indicates that there is developmental delay and significant neurophysiological and biochemical alterations in SSADHD patients, but whether disease presentation varies with age is not known. The investigators propose to determine the natural course of the clinical presentation of SSADHD; to determine the natural course of neurophysiological and biochemical indices known to be altered in SSADHD; and to identify neurophysiological and biochemical predictors of clinical severity. The overall objective is to define the natural course of the clinical, neurophysiological and biochemical spectrum of SSADHD. Secondary objectives include the identification of biomarkers that correlate with disease phenotype and predict clinical outcomes, and the creation of an international SSADHD data repository for future investigation of pathogenesis and therapy.
This study aims to compare a new electronic instrument called (here referred to as the 'Body App') with traditional paper and pencil rating scales for assessing how individuals with eating disorders evaluate their body image.
This phase III trial studies how well nutrition therapy works in improving immune system in patients with bladder cancer that can be removed by surgery. Improving nutrition before and after surgery may reduce the infections and other problems that sometimes occur after surgery.
This phase II trial studies how well carfilzomib, pomalidomide, and dexamethasone work in treating patients with high-risk multiple myeloma. Carfilzomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as pomalidomide and dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving carfilzomib, pomalidomide, and dexamethasone may work better in treating patients with multiple myeloma.
This study will assess the anxiety that patients are experiencing during a Mohs micrographic surgery. The study will compare the feelings of anxiety experienced by patients returning for Mohs surgery after already undergoing the surgery at least one time to feelings experienced by patients who have never had Mohs surgery before. The study will also compare the feelings experienced by patients who have read a vignette about the typical Mohs experience to the feelings of patients who have not read a vignette.
This study leverage a multi-center randomized controlled trial assessing screening-related benefits (i.e. early tumor detection, treatment eligibility, and overall survival) among a racially and socioeconomically diverse population of patients with cirrhosis. However, the randomized controlled trial was not budgeted to assess hepatocellular carcinoma screening-related harms. The goal of this study is to quantify physical, financial, and psychosocial harms across three healthcare settings.
