Healthy Clinical Trials in Dallas, TX

This is a 3-part study that includes a Part A, Part B, and Part C. Part A will study the safety and tolerability of the study drug known as LY3537031 in participants who are overweight and obese. Part B and Part C will study the safety and tolerability of LY3537031 in healthy participants. Part C will contain only Japanese and Chinese healthy participants. Blood tests will be performed to check how much LY3537031 gets into the bloodstream and how long it takes the body to eliminate it. Body weight will be measured. The study will last approximately 20 weeks excluding a screening period. Read Less

The purpose of this study is to evaluate how well LY4005130 is tolerated and what side effects may occur in healthy participants. The study drug will be administered either subcutaneously (SC) (under the skin) or intravenously (IV) (into a vein in the arm). Blood tests will be performed to check how much LY4005130 gets into the bloodstream and how long it takes the body to eliminate it. Part A for the single-ascending doses (SAD) of the study will last about 12 weeks with 9 visits. Part B for the multiple-ascending doses (MAD) of the study will either last about 16 weeks with 13 visits or 20 weeks with 12 visits not counting the time for screening. Read Less

The purpose of this study is to evaluate safety and tolerability of LY4060874 in healthy participants. Study participation may last up to 22 weeks and up to approximately 16 study visits. Read Less

The combination of transcranial magnetic stimulation (TMS) and electroencephalography (EEG) has been suggested as a promising brain imaging tool for identifying biomarkers of brain health. In this pilot study, study investigators will explore the neurophysiological metrics of brain health with a non-invasive brain imaging technique, alongside behavioral and fMRI metrics collected through another study (NCT04869111).

The purpose of this study is to evaluate how well LY3866288 is tolerated and what side effects may occur in healthy participants. The study drug will be administered orally. Blood tests will be performed to check how much LY3866288 gets into the bloodstream and how long it takes the body to eliminate it. The study will last up to approximately 9 weeks including screening. Read Less

Center for BrainHealth is beginning a one-year pilot with local college campuses investigating the impact of (i) brain health assessment and training tools delivered through the online BrainHealth Platform and (ii) in-person educational brain health workshops delivered to college students and faculty/staff, with the overarching goal to better understand how to promote brain-healthier campuses (i.e., reflecting generally positive function across cognitive, social, emotional, and lifestyle domains). This initial study is intended to be a one-year pilot, with findings informing feasibility and efficacy as well as future, more extended and expanded study informing translation to other colleges/universities.

For an overview of the study and link TO REGISTER please go to -- https://brainhealth.utdallas.edu/programs/the-brainhealth-project/ The BrainHealth Project is a ten-year, longitudinal study focused on identifying determinants of brain health and performance. Participants will have the opportunity to complete semi-annual (twice a year) online assessments to track their performance over time. In between semi-annual assessments, participants will have access to online trainings and ongoing supplemental content regarding ways to optimize brain health and performance. Online one-on-one coaching sessions will be offered to participants to answer questions and provide support in applying the information to their daily lives. A small portion of participants will be invited to participate in the brain imaging portion of this study. The main objectives are: (i) to characterize lifestyle, cognitive, and behavioral markers related to an individual's cognitive function from adolescent to elderly ages, (ii) to assess the neural/biological determinants predictive of maintenance of brain health, and (iii) to evaluate the impact of available cognitive and lifestyle interventions on improving and maintaining brain health and performance.

This is a cross-sectional pilot study designed to establish hot and cold cognitive functions and underlying neurocircuitry in older adults with MDD. The investigators will study 120 participants aged 21-80 years old with MDD. All participants will undergo clinical and neurocognitive assessment, and Magnetoencephalography (MEG)/Magnetic resonance imaging (MRI) procedures at one time point. The investigators will also enroll 120 demographically matched comparable, never-depressed healthy participants (controls) to establish cognitive benchmarks. Healthy controls will complete clinical and neurocognitive measures at one time point. To attain a balanced sample of adults across the lifespan, the investigators will enroll participants such that each age epoch (e.g., 21-30, 31-40, etc.) has a total of ten subjects (n=10) in both the healthy control cohort and depressed cohort.

This research is a 5-year observational, longitudinal registry study with no treatment or medication provided as part of participation. Individuals with current or lifetime stimulant use disorder, in addition to healthy control individuals, may be eligible to participate in this study. A variety of assessments and tasks including Magnetic Resonance Imaging (MRI), Electroencephalography (EEG), blood draws, urine drug screens, and both self-report and clinician-rated assessments will be used to assess biomarkers in this population. This study has a visit schedule of four in-person visits and eight remote visits per year. Read Less

This study will randomly assign 2,300 older adults on waiting lists at thirteen Meals on Wheels programs in Florida, Illinois, Maryland, Texas, North Carolina, South Carolina, and California into two groups who will receive: (a) daily delivery of meals, five days a week or (b) a shipment of 10 frozen meals, every two weeks. Researchers will examine participants' Medicare claims to understand if differences in healthcare utilization occur between the two groups within six months after they start receiving meals. Researchers will also ask participants questions prior to receiving meals, and again at three months, to understand how meals impact their ability to obtain food, their feelings of loneliness, and their overall quality of life. The primary study outcome will be the ratio of days spent in institutional settings (i.e., hospital, nursing home) in the six months after participants begin receiving meals. The secondary outcomes include the ratio of days spent in institutional settings in the three months after participants begin receiving meals, food insecurity, subjective isolation/loneliness, and health-related quality of life. The team will also examine differences in dietary intake between the two groups as an exploratory outcome. Read Less

The goal of this project is to test our central hypothesis that the spinal cord neuroplasticity in females will be modulated by the level of estradiol concentration. under aim 1 we will determine the influence of estradiol fluctuations on spinal circuit excitability post afferent (sensory) mediated subthreshold motor priming in young healthy females and males. We will use an established repetitive peripheral nerve electrical stimulation with a stimulation intensity below the motor threshold to prime the spinal motor circuits. under aim 2 we seek to characterize the input output property of spinal circuit excitability after descending drive (motor) mediated priming in young healthy male participants. in aim 3 we will examine the influence of estradiol fluctuations on descending drive mediated motor priming in young healthy females.

The goal of this clinical trial study is to test if patients with idiopathic calcium oxalate kidney stones have an increased absorption of dietary oxalate, which would lead to increased urinary excretion of oxalate. The study will recruit adult patients with a history of calcium oxalate kidney stones and healthy volunteers without kidney stones. Participants will ingest fixed diets containing low and moderately high amounts of oxalate for 5 days at a time ingest a soluble form of oxalate and sugar preparations to test gut permeability collect urine, blood, stool and breath sample during the fixed diets and the soluble oxalate test Read Less
