Clinical trials

The investigators are interested in determining what treatments are effective in reducing inhibition after anterior cruciate ligament (ACL) surgery and helping people increase quadriceps strength. Two interventions that are often used clinically are neuromuscular electrical stimulation (NMES) and vibration. This is a study of how effective these treatments are, whether they work the same for everyone, and if one is better than the other. 22 participants will be enrolled and on study for 2 to 3 weeks.

The overarching goal of this program of research is to reduce smoking-related health disparities by increasing smoking cessation among Black adults. The goal of this research proposal is to determine whether more intensive, culturally specific, evidence-based interventions are more effective at promoting long-term cessation and other key patient-centered outcomes compared to the usual evidence-based standard of care: services provided by a state-run quitline. This study compares the relative effectiveness of three different treatments (Standard, Intensive, and Intensive Incentivized) on long-term smoking cessation (biochemically confirmed abstinence from combusted tobacco at 26-weeks post-target quit day) among Black adults who smoke and want to quit.

This study aims to directly compare and contrast swallowing pressure and impedance measurements obtained from two high-resolution manometry (HRM) systems: the Laborie LMT Pharyngeal System and the Medtronic ManoScan ESO HRM System in healthy adult volunteers. The primary objective is to determine how differences in catheter diameter, sensor configuration, and acquisition platforms influence measurement outcomes. Twenty-five healthy adults will participate in a single, approximately 2-hour visit; the study will be open for one year for data collection and two years for data analysis.

The purpose of this study is to assess the safety and feasibility of an oral probiotic supplement (PS) intervention in individuals with dementia or mild-cognitive impairment (MCI) due to Alzheimer's disease or at risk of dementia due to Alzheimer's disease (AD). 40 participants will be enrolled and can expect to be on study for up to 1 year.

This study is exploring how psilocybin (a psychedelic drug) may improve mood and wellbeing. Many people report feeling better after taking psilocybin, but it is not clear why. The CoPEWell study will test whether these improvements come from the psychedelic experience itself (the "trip") or from direct effects on the brain. To study this, up to 120 participants will be enrolled to receive psilocybin either while awake or asleep and can expect to be on study for up to 4 months.

The goal of this clinical trial is to find out if new Magnetic Resonance Imaging (MRI) computer software will: * help make scans and exams faster * reduce artifacts * make MRI easier to understand * allow technicians to focus more on the participant and less on the scanner Participants will complete one brain MRI imaging session, lasting about 60 minutes.

This study is to find out if an Extra Virgin Olive-Oil-based Water (EVOOW) mix, removes more Fluticasone Propionate (FP) from the mouth than Water alone. 2 strengths of the EVOOW mix will be tested, one with equal parts EVOO and Water (50/50) and one with 3 parts EVOO and 1 part Water (75/25). Removing more FP deposits may help decrease the risk for obstructive sleep apnea (OSA), candidiasis (thrush), and speech and swallow dysfunction. Participants will be on study for up to 3 weeks.

The goal of this study is to test the feasibility and acceptability of an Interactive Media Use Journal (IMUJ) co-developed with youth.

Participants will: * Take oral ASTX727 and retifanlimab through a vein in the arm for about 2 years. * Visit the clinic once every 2 weeks for checkups and tests

This study is being done to see if combining HEPZATO KIT™ with nivolumab and relatlimab (Opdualag™) in the first line setting in patients with metastatic melanoma with liver metastasis is safe, tolerable, and will have a synergistic effect leading to improved clinical outcomes compared to the historic cohort of patients with liver metastasis treated with combination immune checkpoint inhibitor therapy.

The purpose of this observational study is to test a shoe mounted gait monitoring device that was refined with the input of older adults and assess the efficacy of the refinements through a series of tests that involve walking with and without the device.

The goal of this clinical trial is to find out whether learning about well-being impacts the thoughts and feelings of romantic couples. The main question it aims to answer is: * Does gaining knowledge about well-being positively impact individuals and their romantic relationships? Participants will complete online surveys about their thoughts and feelings.

This study is being done to understand the metabolism and impairment profile of methamphetamine (meth). Meth exists as two chemical structures that are mirror images of each other: R-meth and S-meth. S-meth is a strong central nervous system stimulant and used to treat attention deficit disorder (ADD). R-meth is not a strong central nervous system stimulant and is available over-the-counter in nasal decongestant sprays.17 healthy participants will be enrolled for 3 study visits and on study for up to 12 weeks.

The goal of this clinical trial is to see if a mobile phone app can deliver depression treatment to African Americans who are depressed. The main question it aims to answer is if this treatment is effective in reducing symptoms of depression. Participants will attend six 90-minute weekly classes via an app on their phone, and will be asked to complete surveys every week. Participants can expect to be in the study for four months.

This study is being done to see if the investigators can take peripheral blood stem cells from either an adult family member or a closely matched unrelated donor, and run them through a special lab instrument to remove alpha/beta T cells and B cells and then give them to the patient to treat disease. This is an experimental way of doing a hematopoietic stem cell transplant (HSCT). The investigators want to see if the new stem cells will grow without bad graft vs. host disease (GVHD). This treatment approach is experimental in the United States.

This study to find out whether a type of non-invasive electrical brain stimulation called transcranial electrical stimulation with temporal interference (TES-TI) can temporarily change brain activity during sleep-especially sleep spindles (brain rhythms in the \~8-16 Hz range). The investigators are focusing on the thalamus, a deep brain region that helps coordinate brain activity during non-REM sleep. Sleep spindles are often reduced in schizophrenia, so this study is to see whether TES-TI can change spindle activity in individuals with schizophrenia spectrum disorders (SSD) and in healthy adults. To study this, a structural MRI scan will be used to customize where the stimulation electrodes are placed, and then TES-TI will be applied during one of two overnight sleep lab visits while brain activity is recorded with high-density EEG and standard sleep sensors. The other overnight is a baseline/control night during which only sham stimulation is delivered. The goal is to determine whether TES-TI during sleep can increase spindle-frequency activity in this population.

The purpose of this clinical trial is to learn about the impact of the Healthy Minds Program (HMP) on measurements of well-being. The main question it aims to answer is: * Does use of HMP reduce symptoms of depression? Participants will complete a 4-week well-being program.

The purpose of the study is to show if it's possible to use a special kind of ultrasound called backscatter quantitative ultrasound (bQUS) to check on a baby's lungs when the mother is 36 weeks pregnant. 16 participants will be on study for a single 30 minute ultrasound between 32 and 36 weeks of pregnancy.

The purpose of this research is to determine the expression of prostate specific membrane antigen (PSMA) in human epidermal growth factor receptor 2 (HER2)-negative, androgen receptor (AR)-positive metastatic breast cancer, and to determine its role in resistance to the anti-androgen, bicalutamide. The investigators hypothesize that PSMA expression will correlate with resistance to anti-androgen therapies, as has been documented in prostate cancer, and this can be used to select patients most likely to benefit from these therapies in future clinical trials. 15 people with HER2-negative, AR-positive metastatic breast cancer will be enrolled and be on study for about 3 days.

The goal of this study is to develop a machine-learning guided recovery messaging system. The main question it aims to answer is can messages be used to: * help people to improve their health * make changes in people's lives to address alcohol and substance use Participants will: * complete surveys * use a recovery-support digital therapeutic system
