Clinical trials

The overarching goal of this research is to determine the most effective approach for helping dual users of cigarettes and electronic nicotine delivery systems (ENDS) quit smoking. 500 participants will be enrolled and can expect to be on study for 12 months.

The goal of the current study is to evaluate a decision-support tool intended to help primary care providers (PCPs) communicate with patients about blood biomarker testing for Alzheimer's Disease, enhancing shared-decision making and information sharing in the clinical space. The main questions it aims to answer are: * Is the decision-support tool accepted and easy to use for PCPs? * Does using the tool improve shared decision-making during clinical encounters? Researchers will compare clinical encounters between PCPs who do not use the tool to discuss blood biomarker testing for Alzheimer's Disease, versus PCPs who have been trained to utilize the tool during clinical encounters to see whether the tool effectively facilitates shared-decision making.

The goal of this clinical trial is to gain more information about how fibroblast activation protein inhibitor (FAPI) binds to a certain type of cells in fibrotic lung tissue and how this information can be used to better diagnose and track fibrotic lung disease activity. Participants will undergo up to 4 PET/MRI scans using the FAPI radiotracer.

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 is a caregiver support program for family caregivers of autistic young adults (ages 18 to 26) as their family members navigate young adulthood. The program includes six 60-minute virtual sessions focused on making sense of caregiving roles during young adulthood, reflecting on everyday family experiences, supporting decision-making within families, deciding when and how to share experiences with others, and thinking about the future.

This study to evaluate the leak integrity of the LapBox Manual Containment System for laparoscopic hysterectomy and myomectomy. The goal is to determine the integrity of this containment system in order to increase surgical safety. 30 adult females who require laparoscopic hysterectomy or myomectomy for management of uterine fibroids will be enrolled and will be on study the day of surgery.

The purpose of this research is to evaluate whether adding histotripsy to maintenance durvalumab increases immune response and to assess the safety of this combination for participants with advanced intrahepatic cholangiocarcinoma (iCCA). Histotripsy is a non-invasive, non-thermal treatment that uses focused ultrasound energy to destroy tumor tissue. 12 people will be enrolled in this study.

The purpose of this study is to evaluate the impacts of informal educational tools used by the Midwest Center of Excellence for Vector-Borne Disease in collaboration with the Wisconsin Department of Health Services. Children aged 6-12 will receive an educational activity about ticks. They will be asked questions before and after the activity and will participate for between 30-60 minutes.

This study is to find out whether and how a type of non-invasive electrical brain stimulation called transcranial electrical stimulation with temporal interference (TES-TI) can temporarily change brain activity in healthy adults. A structural MRI scan will be used to customize where the stimulation electrodes are placed for each participant to deliver TES-TI during three afternoon sessions at rest with eyes closed. Brain activity is recorded with high-density EEG. Up to 24 participants will be enrolled and on study for 3 to 12 weeks.

The purpose of this study is to compare the effects of an intensity-, volume-, and time under tension-matched eccentric hamstring exercise intervention with the Romanian deadlift (RDL) and the Nordic hamstring exercise (NHE) to a sprint-specific training program on hamstring muscle architecture, volume, sprint performance, strength, and power. Participants will be assigned to complete one of the 3 hamstring interventions for 10 weeks.

The goal of this clinical trial is to learn if alisertib in addition to usual care works to treat HR+/HER2+ breast cancer. The main questions it aims to answer are: * Does alisertib stop the communication between HR and HER2? * Are there genetic markers that predict how well someone's cancer will respond to alisertib? Participants will receive alisertib in addition to their usual care.

The purpose of this clinical trial is to find out whether a medication, called letermovir, can help prevent a virus called cytomegalovirus (CMV) in participants who receive a kidney or liver transplant and who have already been exposed the CMV. Participants will take letermovir for 84 days.

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 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.

This study integrates and evaluates a series of novel MRI methods for quantifying blood perfusion and tissue microstructure. The proposed perfusion and microstructure measures may provide biomarkers for fibrosis, cirrhosis, portal hypertension, and response to treatment. The precision of these methods will be evaluated in 110 participants, including healthy volunteers, people with chronic liver disease (CLD), and people with liver fibrosis.

Current tuberculosis (TB) treatment is effective (works well), but it takes a long time to cure TB. This study will evaluate if TB treatment with a higher dose of rifampicin, one of the TB medicines, and shorter TB treatment duration is as effective and safe as the standard, TB treatment (with the usual rifampicin dose and usual duration). This study hopes to find a better shorter treatment that works as well as the current treatment (standard of care). This could benefit children worldwide who are getting TB treatment. Children 3 months to less than 10 years of age who have drug-susceptible TB (can be successfully treated with standard TB medicines) are eligible for this study.

The purpose of this randomized behavioral clinical trial is to examine whether a well-being intervention can improve both psychological well-being and physical outcomes in adults with Irritable Bowel Syndrome (IBS). The study aims to assess whether this intervention decreases anger, anxiety, and depression; increases self-esteem, empathy, and hope; and improves quality of life indicators such as IBS symptom severity, sleep quality, fatigue, and diet. Participants can expect to be on study for up to 9 months.

This study compares two different imaging procedures to each other, one using positron emission tomography (PET) with fluorothymidine F-18 (FLT) (FLT PET for short), and the other using chemical shift-encoded (CSE) magnetic resonance imaging (MRI) or CSE-MRI for short, to determine specifically if CSE-MRI is as accurate as FLT PET in telling the difference between active and inactive marrow. The best way to do the comparison between the two imaging procedures is if they are done at the same time on the same patient. This is possible with use of a scanner at the University of Wisconsin Hospitals and Clinics (UW Health), the GE SIGNA PET/MR scanner. The prediction is that CSE-MRI as accurate as FLT at telling the difference between active and inactive marrow in patients with metastatic prostate cancer, and that is the primary reason for this study. 15 participants will be enrolled and on study for up to 14 months.

This study is to evaluate the effectiveness of targeted Transcranial Electrical Stimulation with Temporal Interference (TES-TI) interventions to boost Non-Rapid Eye Movement (NREM) sleep, decrease seizures and promote emotional health in patients with epilepsy. Up to 24 participants (8 control participants for technical optimization prior to recruitment and 16 patients with epilepsy) will be enrolled and can expect to be on study for up to 24 months.

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 goal of this clinical trial is to learn if ASTX727 can be combined with retifanlimab to treat Merkel cell cancer. It will also learn about the safety of combining these drugs. The main questions it aims to answer are: * Can the combination shrink cancer and lower the chance of the cancer growing or spreading? * Is the combination better than standard of care for Merkel cell cancer? 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

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.

This study is being done to see if combining HEPZATO KIT™ with nivolumab and relatlimab (Opdualag™) 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 goal of this clinical trial is to find out whether a type of electrical brain stimulation, called temporal interference stimulation, can temporarily change the way different parts of the brain communicate with each other. Participants will: * Complete two stimulation phases - overnight and during wakefulness * Undergo two MRIs per study phase
