Clinical trials

This is a single-center, open-label, single-arm pilot study evaluating topical ruxolitinib (OPZELURA) as a treatment for adults with Pyoderma Gangrenosum (PG), a chronic inflammatory skin condition that causes painful ulcers. Approximately 12 participants will apply ruxolitinib cream twice daily for 24 weeks while continuing standard wound care, with the goal of determining whether the drug helps target ulcers heal completely without the need for systemic immunosuppressive therapy. Participants will be followed for a total of 28 weeks, with the option to continue treatment in a 48-week open-label extension if they respond well and remain safe on the drug. The study is sponsored by Oregon Health \& Science University and funded by Incyte Corporation.

This work will address an important gap in physical therapy rehabilitation after concussion. Physical therapy usually focuses on how the brain processes sensory information such as inner ear and vision for balance rehabilitation, but our recent research shows that people with imbalance more often have a problem with how they can respond to imbalance (i.e., motor activation). While there are complex laboratory tools to test motor activation for balance, these tests are not practical for the clinic. The goal of this study is to create both an exercise intervention focused on motor activation after concussion and simple, but objective and instrumented (wearable sensors), clinical measures of motor activation. Objectives: This research study has three aims. 1) The investigators and study team will develop an exercise program to improve the problems with how one's body responds to imbalance (i.e., improve motor activation) after a concussion. The study team will use a Community Based Participatory Research (CBPR) approach by collaborating with a team of people with a broad range of experience related to concussion. The study team will form a Community Advisory Board (CAB) that will include patients who have had a concussion, healthcare professionals with expertise in concussion, and healthcare administrators. The CAB will contain people working in the military and civilians. 2) The investigators will compare our new motor-focused physical therapy intervention to the standard sensory focused balance intervention. The goal is to determine which intervention program is more effective in treating balance problems after a concussion. The investigators hypothesize that the motor-focused program will help patients more compared to the sensory program. 3) The investigators and study team will create and test several balance tests that can be used in the clinical without expensive research equipment to our standard research-based motor activation tests. This aim will allow the study team to determine if the clinical tests perform as well as the research-grade tests. To make the test useful to clinicians, the study team will use simpler technology like smart-phone applications, wearable sensors, and virtual reality goggles that are both affordable and practical for healthcare providers.

The primary aim is to determine the feasibility of enrolling and 15 women with chronic pelvic pain (CPP) that have failed one conventional for CPP to obtain preliminary safety data on a single administration of a moderate dose of pharmaceutical grade psilocybin (25 mg) in combination with psychotherapy sessions (two pre-dose preparatory and three post-dose integration sessions).

The primary aim of this project is to use a randomized single-blind sham-controlled study to investigate if high frequency repetitive transmagnetic stimulation (HF-rTMS) can modulate cue-induced craving in adult methamphetamine (METH) users. The investigators hypothesize that HF-rTMS directed at left dorsolateral prefrontal cortex (DLPFC) will result in a reduction in craving for METH compared to sham-controlled rTMS in adults with methamphetamine use disorder (MUD) as evidenced by validated measures of METH craving. Neurobiologically, the investigators anticipate rTMS mediated stimulation of the DLPFC could result in inhibition of cue-induced craving through potential disruption of involved circuitry. The current project proposes that participants who are recently abstinent from METH will be randomized into four experimental groups to provide two rTMS conditions (real versus sham) and two picture cues conditions (METH versus neutral). The experiment will have an induction phase where each subject will receive 10 daily treatments within 2 weeks. Just before each rTMS/sham session participants will be shown visual cues (METH or neutral). Participants will then undergo a maintenance phase for an additional month with assessments to evaluate craving and relapse. Urine samples for urine drug screening (UDS) will be collected at screening day and on days 1, 5 and 10. Just before each rTMS/sham session participants will be shown visual cues (METH and neutral). VAS craving scores will be assessed before and after picture presentation and after the rTMS/sham session. Before the first and 10th treatment session, participants were evaluated by the the Stimulant Craving Questionnaire (STCQ) and the Severity of Dependence Scale (SDS) questionnaires. Participants will then undergo a maintenance phase for an additional month. During the first week of maintenance, three rTMS/sham sessions will be administered. During each of the following 3 weeks, one rTMS/sham session will be given per week. As with the induction phase, urine samples will be collected for screening and STCQ and the SDS questionnaires will be completed at each maintenance session. To evaluate the long-term effects of the rTMS treatment, the investigators plan on contacting participants 6 months after treatment termination for all subjects who completed the 10 treatment sessions. During that phone conversation, craving and relapse will again be assessed.

The purpose of this study is to learn more about a smartphone application (app) called DailyDose, an investigational decision support tool that may help in managing your diabetes. DailyDose tracks your continuous glucose monitoring (CGM) data, insulin use, and exercise, and uses this information to provide personalized recommendations for insulin dosing and carbohydrate intake during exercise or low blood sugar events. We want to find out if DailyDose can help lower blood sugar levels as measured by the hemoglobin A1c (HbA1c) test.

Numerous clinical trials have demonstrated that transthyretin (TTR)-directed medical therapies can reduce the rate of functional decline in patients with transthyretin cardiac amyloidosis (ATTR-CM). However, patients treated with these therapies often experience a progressive reduction in exercise capacity despite treatment. Further, no randomized controlled trials (RCTs) have assessed the effects of exercise intervention in patients with ATTR-CM receiving TTR-directed therapy.

Exercise intervention trials in patients with hypertrophic cardiomyopathy (HCM) have demonstrated an association with improvement in resting and exercise hemodynamics, ventricular remodeling, and anxiety/depression. However, no randomized controlled trials (RCTs) to date have assessed the effects of exercise intervention in patients with HCM on cardiac myosin inhibitors (CMIs). This trial aims to evaluate the efficacy of a 12-week individualized exercise training program in HCM patients receiving aficamten.

The purpose of this study is to compare the effectiveness of two defibrillator pad placements, one where pads are placed on the front of the chest and back (anterior-posterior \[AP\]) and one where the pads are placed on the front and side of the chest (anterior-lateral \[AL\]), for the treatment of cardiac arrest. Both pad placement locations are recommended for use by the American Heart Association (AHA) and International Liaison Committee on Resuscitation (ILCOR) and are used in standard treatment. The investigators are hoping to find out if one pad position is more effective than the other in the treatment of cardiac arrest.

The overall objective of this randomized clinical trial is to test the effectiveness of a personalized approach to the surgical treatment of OSA in children with Down syndrome (DS).The estimated prevalence of obstructive sleep apnea (OSA) in children with DS ranges from 45-83%, compared to 1-6% in the general pediatric population. Untreated OSA in children has been associated with daytime sleepiness, cognitive or behavioral problems, and cardiovascular complications, all which are common in children with DS. Adenotonsillectomy (AT) is the first line treatment for OSA in children, however, most large studies of AT outcomes have excluded children with DS. Available evidence demonstrates that AT is far less effective in children with DS than in the general pediatric population, with 48 to 95% of children with DS having persistent OSA after AT. Medical treatments such as positive airway pressure (PAP) therapy are frequently inadequate or poorly tolerated in this population, so many children with DS and OSA remain untreated. Drug-induced sleep endoscopy (DISE) enables direct observation of the sites and patterns of obstruction during sedated sleep using a flexible endoscope passed through the nose into the pharynx. DISE was developed to guide surgical decisions in adult OSA, and in recent years has also been used to design personalized surgical interventions in children. Using this DISE Rating Scale, the investigators have demonstrated that children with DS are more prone to tongue base and supraglottic obstruction than non-DS children, suggesting the need for more personalized surgical treatments that are tailored to the common sources of obstruction in this population. Several small case series demonstrate that DISE-directed surgery can be effective in treating OSA in children with DS. However, because there have been few prospective studies and no randomized trials comparing different treatment options in this population, there remains uncertainty about whether such a personalized approach leads to superior outcomes compared to the first line AT. It is the investigators' hypothesis that personalized DISE-directed surgery that uses existing procedures to address specific fixed and dynamic anatomic features causing obstruction in each child with DS will be superior to the current first line approach of AT. This novel approach may improve OSA outcomes and reduce the burden of unnecessary AT or secondary surgery for persistent OSA after an ineffective AT.

The purpose of this study is to find out if magnetic resonance (MRI)-guided high-intensity focused ultrasound (HIFU) is safe and effective for treating medically refractory generalized epilepsy. HIFU is a procedure that delivers ultrasonic waves to brain regions with great precision to remove tissue that may cause problems. HIFU is approved by the Federal Drug Administration (FDA) for treating patients with essential tremor. This study aims to find out if HIFU can safely reduce seizure burden in patients with medically refractory generalized epilepsy (MRGE) using metrics commonly used in other treatments for epilepsy, and by the change in frequency of convulsive (generalized tonic-clonic) seizures before and after the intervention.

The objective of this study is to investigate and utilize spinal cord stimulation (SCS) as an effective approach to eliciting weight loss and potentially alleviating Type 2 diabetes mellitus (DM), as evidenced by increasing metabolism of adipose tissue.

The purpose of the study is to learn more about an experimental drug bimekizumab that may be helpful for Pyoderma Gangrenosum (PG). Bimekizumab will be referred to as the study drug throughout this form. The investigators are hoping to find out if bimekizumab helps in healing PG wounds. The study drug is experimental. It has been approved by the FDA for use in adults with psoriatic conditions but not for Pyoderma Gangrenosum (PG).

Breakthrough T1D has awarded support for a joint University of Michigan-Oregon Health \& Science University Center of Excellence (CoE) to address cardio-renal complications in T1D. The overarching hypothesis of the CoE is that individuals with T1D have unique endophenotypes determining their progression towards cardio-renal end organ damage. Defining the underlying molecular programs in T1D endophenotypes provides the rationale for testing existing or new drug candidates in mechanistic trials targeting T1D cardio-renal complications by matching endophenotypes to targeted therapies.

This is a cross-sectional study with an optional intervention that will examine how extreme sleep durations relate to cardiovascular health, physical activity, and sleep quality by studying three groups of participants: short sleepers (≤ 6 hrs), long sleepers (≥ 9 hrs), and average duration sleepers (7-8 hrs). The optional intervention asks participants to maintain an 8-hour per night regular sleep schedule for one week.

The purpose of this study is to learn more about why some people are at greater risk for oral emergency contraceptive failure while others are not. The investigators want to learn if genetic differences impact the risk of emergency contraception failure.

The goal of this clinical trial is to learn if extended post-operative oral tranexamic acid (TXA) - a medication that reduces bleeding by slowing the breakdown of blood clots - can improve functional recovery following surgery in adults undergoing primary total knee or hip arthroplasty for osteoarthritis. The main question it aims to answer is: Does extended post-operative oral TXA improve functional outcomes at 6 weeks post-operatively compared to standard perioperative TXA alone? Researchers will compare patients receiving extended oral TXA to patients receiving matching placebo capsules on the same schedule to see if the extended TXA regimen reduces blood loss, improves early functional outcomes, and reduces pain without increasing complication rates. Participants will receive standard perioperative oral TXA (1.95 g) prior to surgical incision, along with standard VTE prophylaxis. They will be randomly assigned to receive either oral TXA or matching placebo capsules once daily on post-operative days 1, 2, and 3. Participants will attend follow-up visits at 2, 6, and 12 weeks post-operatively to complete functional outcome questionnaires, pain assessments, and - for knee replacement patients - range of motion measurements.

The goal of this clinical trial is to learn if a therapist training program can help providers in Part C Early Childhood Settings use powered mobility (PM) with young children who have cerebral palsy (Gross Motor Function Classification System Levels IV-V). The study will also look at whether this training is practical and useful for therapists, families, and children. The main questions it aims to answer are: 1. Can therapists successfully use the training to provide powered mobility interventions in home and early childhood settings? 2. Do families and children find the intervention acceptable and helpful? 3. What benefits do children show in mobility, participation, and engagement after using powered mobility? In this study, therapists and families will: 1. Take part in a training program about how to use powered mobility with young children 2. Use powered mobility devices (Permobil Explorer Mini) with children during everyday routines 3. Complete surveys, interviews, and observations about their experiences

The purpose of this study is to compare the effectiveness of a novel personalized surgical approach to the standard AT in children with small tonsils (ST). This will be accomplished by randomizing children with ST and OSA to one of these two treatments and comparing outcomes after 6 months. It is the investigators' central hypothesis that a personalized drug-induced sleep endoscopy (DISE)-directed surgical approach that uses existing procedures to address the specific fixed and dynamic anatomic features causing obstruction (ie, anatomic endotypes) in each child with ST will perform better than the currently recommended standard first line approach of AT. This novel approach may improve OSA outcomes and reduce the burden of unnecessary AT or secondary surgery for persistent OSA after an ineffective AT. To test this hypothesis, the investigators propose to study children aged 2-17 years with small tonsils and OSA.

In this study, the investigators compare two novel primary care interventions (School Readiness Checklist vs. Kinder Coaching) for low-income parents, which were co-developed by parent, clinical, and educational stakeholders. This R01 builds evidence on a low touch (low intensity, lower cost intervention) School Readiness Checklist compared to high touch (higher intensity, embedded program) Kinder Coaching with Community Health Workers in a hybrid effectiveness-implementation RCT.

In this study, the investigators will tailor an existing intervention (Rural Caregiver Heart Health Education (RICHH)) protocol and test its feasibility, acceptability, and initial effect with grandparent caregivers.
