Vanderbilt Clinical Trials

The research team is recruiting 900 children between the ages 5-17 with obesity from Tennessee and Louisiana. The team is assigning children and their caregivers by chance to one of five groups. In the first group, 300 children and their caregivers receive 26 hours of IBT. In the second group, 300 children and their caregivers receive 13 hours of IBT. The remaining three groups of 100 children and their caregivers receive 16, 19, or 22 hours of IBT. Children's healthcare providers, nutritionists, and social workers are providing IBT to each of the groups over six months. At the start of the study and again after one year, the research team is measuring the children's body mass index, or BMI. BMI is a measure of a person's body fat based on their height and weight. The team is also looking at the children's: - Diet - Exercise - Sleep - Media use - Quality of life

Patients with pulmonary arterial hypertension (PAH) have reduced health related quality of life (HRQOL) and impaired exercise capacity. Despite fourteen approved therapies, most patients die within ten years. Increasing physical activity is highly efficacious in PAH, resulting in six-minute walk distance (6MWD) and HRQOL improvement that often exceeds the effect of medications. Prior activity studies required inpatient rehabilitation, which is impractical, hard to sustain, and poorly scalable to a rare disease. The Investigators propose a randomized trial of smart texts versus usual care for 6 months. The Investigators will randomize 100 PAH patients to the mHealth intervention or usual care. The Investigators will test the effect of a text-based mHealth intervention on HRQOL in PAH using the PAH-specific emPHasis-10 questionnaire. The Investigators will also test the effect of an mHealth intervention on exercise capacity, measured by a supervised home-based 6MWD test. Finally, the Investigators will examine the effect of the intervention on time to clinical worsening (composite of PAH therapy escalation, PAH hospitalization, and death) one year after randomization.

Ventilated pediatric patients are frequently over-sedated and the majority suffer from delirium, a form of acute brain dysfunction that is an independent predictor of increased risk of dying, length of stay, and costs. Universally prescribed sedative medications-the GABA-ergic benzodiazepines-worsen this brain organ dysfunction and independently prolong duration of ventilation and ICU stay, and the available alternative sedation regimen using dexmedetomidine, an alpha-2 agonist, has been shown to be superior to benzodiazepines in adults, and may mechanistically impact outcomes through positive effects on innate immunity, bacterial clearance, apoptosis, cognition and delirium. The mini-MENDS trial will compare dexmedetomidine and midazolam, and determine the best sedative medication to reduce delirium and improve duration of ventilation, and functional, psychiatric, and cognitive recovery in our most vulnerable patients-survivors of pediatric critical illness.

The purpose of this observational study is to find the best measures to define how well a person with eosinophilic disorder is doing. People with EoE, EoG, EoN and EoC normally undergo endoscopy and/or colonoscopy where cells are collected for microscopic analysis. Treatments are then decided based on how the cells look. We are aiming to compare different tissue components such as inflammatory cell types with clinical symptoms. We want to see if scores on standard questionnaires can give us an idea how well the person is doing.

Firearm injuries are the leading cause of death for American youth. Strikingly, firearm suicide among adolescents is growing faster than other groups. Lethal means counseling is standard of care, however, infrequently occurs despite pediatricians recognizing the importance. Lack of time, topic discomfort, and inadequate resources for families are commonly reported barriers to counseling. By addressing these factors, we can improve counseling with the ultimate goal of increasing safe storage and reducing firearm injuries in youth. Children admitted in acute mental health crises while awaiting psychiatric hospital placement are a population at greater risk of suicide. We plan to implement a pilot intervention to offer secure storage counseling and storage device distribution to families of behavioral health patients who indicate firearm ownership on initial screening. The goal of this project is to evaluate the feasibility and acceptability of firearm secure storage counseling and device provision in the inpatient setting.

The primary objective of the Vanderbilt Alzheimer's Disease Research Center (VADRC) is to provide local and national researchers with access to a well-characterized and diverse clinical cohort, including participant referrals, biosamples, clinical data, and neuroimaging data. The VADRC Clinical Core will create an infrastructure to support research efforts of both local and national investigator studies to develop early detection, prevention, and treatment strategies for Alzheimer's disease. The Clinical Core intends to enroll up to 1000 participants, including individuals who are cognitively unimpaired, have mild cognitive impairment, or have Alzheimer's disease. This cohort of about 1000 participants will be called the Tennessee Alzheimer's Project. Participants will be seen annually for comprehensive clinical characterization and then referred to other studies to enhance Alzheimer's disease research activities.

The 2021 ACR RA treatment guideline, based on widely acknowledged low to moderate quality evidence, recommends switching to a non-tumor necrosis factor (TNFi) biologic (choose among existing medications, currently, rituximab, abatacept, tocilizumab, or sarilumab) or a targeted synthetic DMARD arm (tsDMARD; choose among existing medications, currently, tofacitinib, baricitinib, upadacitinib) in patients with active RA despite the use of a TNFi-biologic. In practice, most patients receive another TNFi-biologic, i.e., a second TNFi-biologic first. This is not based on solid evidence, but on arbitrary algorithms often proposed by health insurance plans, and/or physician experience and habit (TNFis launched 22 yrs ago vs. the first tsDMARD 8 years ago vs. first non-TNF-biologic launched 17 years ago). This study will fill a critical knowledge gap by generating CER data for important PROs between these treatment options, switching to a non-TNFi biologic or a tsDMARD in patients with active RA despite the use of a TNFi-biologic.

Using a single-case multiple baseline across participants design, this study aims to explore the effectiveness of parent-implemented Broad Treatment Speech Recast supplemented with traditional clinician-led articulation therapy on speech production in elementary-aged deaf and hard of hearing children. To address these objectives, the following research questions will be investigated: 1. Does drill-based articulation therapy, administered by a speech-language pathologist, improve speech sound production in DHH children when parent-implemented BTSR is concurrently utilized at home? 2. Does the combination of parent-implemented BTSR and clinician-led traditional articulation therapy result in generalization of speech sound accuracy at the conversation level?

This study will use an anticholinergic pharmacological probe to examine attention network function in SCD using EEG. The overall hypothesis is that in older adults with SCD, normal cognitive performance is maintained by compensatory attention network activity, supported by enhanced cholinergic function. The investigators anticipate that SCD will be associated with greater compensatory attention network activity and that disrupting this compensatory process through anticholinergic challenge will result in a greater negative effect on attentional performance (Attention Network Test, ANT) and attention network functioning (EEG) in older adults with greater subjective cognitive concern.

This study will use an observational cohort to cross-sectionally and longitudinally relate vascular health to clinical, imaging, and biological markers of early Alzheimer's disease and cerebrovascular disease among aging adults. Adjusting for relevant clinical covariates, we will test the hypothesis that vascular health is associated with clinical, brain magnetic resonance imaging (MRI), neuropsychological, and cerebrospinal fluid markers of early cerebrovascular and Alzheimer's disease changes (i.e., prior to the onset of significant cognitive decline or dementia). Secondarily, we will examine medical and genetic factors that might mediate associations between vascular health and brain aging, such as inflammatory processes, insulin resistance, and genetic factors (e.g., APOE, a susceptibility risk factor for dementia). Findings will advance knowledge regarding the role that vascular health plays in brain aging.

Among people living with HIV, heavy drinking increases the risk of heart disease and death. Studies suggest that alcohol changes the number and kind of bacteria in your gut and these changes increase the risk of heart disease and death. This randomized controlled trial will determine whether a pill containing healthy gut bacteria can increase the number good bacteria in the gut, lower levels of inflammation, and lower the risk of heart disease and death.

This phase III trial compares the effect of giving triptorelin vs no triptorelin in preventing ovarian damage in adolescents and young adults (AYAs) with cancer receiving chemotherapy with an alkylating agents. Alkylating agents are part of standard chemotherapy, but may cause damage to the ovaries. If the ovaries are not working well or completely shut down, then it will be difficult or impossible to get pregnant in the future. Triptorelin works by blocking certain hormones and causing the ovaries to slow down or pause normal activity. The triptorelin used in this study stays active in the body for 24 weeks or about 6 months after a dose is given. After triptorelin is cleared from the body, the ovaries resume normal activities. Adding triptorelin before the start of chemotherapy treatment may reduce the chances of damage to the ovaries.

This is a Phase III clinical randomized control trial to investigate differences between patient with an infected nonunion treated by PO vs. IV antibiotics. The study population will be 250 patients, 18 years or older, being treated for infected nonunion after internal fixation of a fracture with a segmental defect less than one centimeter. Patients will be randomly assigned to either the treatment (group 1) PO antibiotics for 6 weeks or the control group (group 2) IV antibiotics for 6 weeks. The primary hypothesis is that the effectiveness of oral antibiotic therapy is equivalent to traditional intravenous antibiotic therapy for the treatment of infected nonunion after fracture internal fixation, when such therapy is combined with appropriate surgical management. Clinical effectiveness will be measured as the primary outcome as the number of secondary re-admissions related to injury and secondary outcomes of treatment failure (re-infection, nonunion, antibiotic complications) within the first one year of follow-up, as defined by specified criteria and determined by a blinded data assessment panel. In addition, treatment compliance, the cost of treatment, the number of surgeries required, the type and incidence of complications, and the duration of hospitalization will be measured.

This phase I/II trial tests the safety and efficacy of split-course adaptive radiation therapy in combination with immunotherapy with or without chemotherapy for the treatment of patients with stage IV lung cancer or lung cancer that that has spread to nearby tissue or lymph nodes (locally advanced). Radiation therapy is a standard cancer treatment that uses high energy rays to kill cancer cells and shrink tumors. Split-course adaptive radiation therapy uses patient disease response to alter the intensity of the radiation therapy. Immunotherapy with monoclonal antibodies such as pembrolizumab, ipilimumab, cemiplimab, atezolizumab or nivolumab may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs like carboplatin, pemetrexed, and paclitaxel 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 split-course adaptive radiation therapy with standard treatments like immunotherapy and chemotherapy may be more effective at treating stage IV or locally advanced lung cancer than giving them alone.
