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 DISRUPT-AF Registry is an observational, prospective, multi-center, non-randomized, real-world registry designed to obtain clinical experience with the Farapulse Pulsed Field Ablation System for the treatment of atrial fibrillation (AF).
The goal of this clinical trial is to evaluate how differences in specific parts of our DNA can influence how individual bodies break down the hormones contained within oral contraceptive pills, which could affect how well these birth control pills work to prevent pregnancy. The investigators are also interested in exploring how these differences in our DNA can also explain why patients taking the exact same formulation of birth control pill will experience very different side effects. The main questions it aims to answer are: - Do individuals with the CYP3A7*1C variant have increased metabolism of both desogestrel and ethinyl estradiol when taking a combined oral contraceptive pill? - Do individuals with the CYP3A7*1C variant experience higher rates of breakthrough ovulation while taking a desogestrel/ethinyl estradiol combined oral contraceptive pill? - What novel genetic loci are associated with alterations in steroid hormone pharmacokinetics and pharmacodynamics among a larger cohort of combined oral contraceptive pill users? Participants will take a specific formulation of combined oral contraceptive pill (desogestrel/ethinyl estradiol) and undergo the following procedures: - Blood draw to measure the amount of progestin and estrogen in their system from the combined oral contraceptive pill - Questionnaires to assess side effects possibly caused by the combined oral contraceptive pill - Blood draw to measure endogenous hormone levels and biomarkers that may be affected by the combined oral contraceptive pill - A transvaginal ultrasound to measure any ovarian follicles (optional procedure)
The primary objective of this study is to investigate the cognitive benefits of ozanimod in individuals with Multiple Sclerosis (MS). The study aims to understand the neural basis of cognitive improvement in Relapsing-Remitting MS patients under ozanimod treatment using neuroimaging and behavioral techniques to characterize the brain and behavioral changes due to ozanimod treatment.
This clinical trial assesses differences in the delivery of THC to the bloodstream depending on whether nicotine vapes are used before or after THC. While there has been much recent publicity about vaping products and concern about their safety considering their increasing use for THC administration, the THC delivery profile associated with THC liquid vaping products in human subjects is currently unknown. Importantly, how the delivery to the bloodstream of THC vaping liquids compare to delivery from smoked cannabis, which is the most used method of cannabis delivery, will serve as an important benchmark for evaluating the delivery and effects of THC vaping products, and their relative safety.
The goal of this study is to determine the response of the study drug loratinib in treating children who are newly diagnosed high-grade glioma with a fusion in ALK or ROS1. It will also evaluate the safety of lorlatinib when given with chemotherapy or after radiation therapy.
The purpose of this study is to determine the effect of Losartan, an Angiotensin II Receptor Blocker (ARB), on the formation development of arthrofibrosis in patients who have had a primary total knee arthroplasty. This study aims to assess the post-operative range of motion and the incidence of MUA within three months following the index arthroplasty in the treatment arm (losartan) and the control arm.
The goals of this Pilot Trial are to test the preliminary efficacy of Problom-Solving Therapy (PST)-APPLE Watch in a 2-arm pilot Randomized Control Trial (RCT), vs education only-control to reduce alcohol use disorder symptoms and improve alcohol abstinence.
Many patients suffer from chronic non-healing wounds as well as acute wounds. There is a need to develop treatments to accelerate and improve healing of chronic and acute wounds. More research is needed to evaluate the role of 4-aminopyridine (4-AP), a promising new agent with an excellent safety profile, on wound healing. The investigational treatment will be used to evaluate the role of (4-AP) on the treatment of wounds to accelerate wound healing in healthy adults. The purpose of this study is to evaluate the role of 4-AP on the treatment of wounds to accelerate healing. The investigational treatment will be used to test the hypothesis that 4-AP can speed wound healing.
The goal of this clinical trial is to test cannabidiol in Sanfilippo syndrome. The main questions it aims to answer are: 1) determine the safety of cannabidiol in Sanfilippo syndrome, and 2) explore the efficacy of cannabidiol in treating the neurobehavioral symptoms and functional outcomes of Sanfilippo syndrome. Each participant's caregiver will be asked to complete surveys related to the participant's behavior, mood, sleep, stooling, pain, and caregiver stress intermittently throughout the study. All participants will be enrolled into one of two cohorts based on enrollment order: 1. Sentinel Safety Cohort (first 5 participants) - all participants treated with Epidiolex (cannabidiol) 2. Controlled Cohort (next 30 participants) - participants randomized 1:1 (equal chance) to start treatment with Epidiolex (cannabidiol) or placebo for 16 weeks, followed by an 8-week washout period (no treatment). Participants then switch to the opposite treatment group for 16 weeks followed by all participants treated for 52 weeks with Epidiolex (cannabidiol).
This research study is evaluating the safety and efficacy (performance) of the Bausch + Lomb enVista Beyond Hydrophobic Acrylic Extended Depth of Focus Intraocular Lens (IOL) in subjects who receive this IOL in both eyes.
