There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The primary objective of this study is to estimate the incidence of Anti-Natalizumab Antibodies (ANAs) in the cohort of natalizumab-naïve and other MS monoclonal antibody (mAb)-naive participants who start receiving natalizumab subcutaneous (SC) injections. The secondary objectives of this study are to estimate the proportion of participants detected with ANAs when switched from natalizumab intravenous (IV) to natalizumab SC (natalizumab-experienced cohort); to evaluate serious adverse events (SAEs), including injection reactions and hypersensitivity reactions, by ANA status and to assess the proportion of participants who had MS relapse, by ANA status.
The investigators will conduct an randomized controlled trial (RCT) among people with Parkinson disease (PD) and freezing of gait (FOG) to evaluate the feasibility of a mindfulness intervention compared to a educational program about FOG. FOG is a severe motor disturbance that prevents people from stepping normally and is associated with anxiety, frustration, sedentary behaviors, poorer quality of life, and falls. Mindfulness-Based Stress Reduction (MBSR) is an evidence-based practice that creates a culture to reduce stress and anxiety by increasing conscious awareness and self-compassion. In this study, the investigators will develop a mindfulness-based walking intervention to address both mental health and mobility challenges that constitute FOG.
Suicide is the second leading cause of death for 15-to-24-year-olds in the United States. Compared to their heterosexual and cisgender peers, sexual and gender minority (SGM) adolescents report significantly higher rates of suicidal ideation and suicide attempts. Unfortunately, many barriers complicate the implementation of suicide prevention in SGM communities. SGM youth often report feeling unwelcome and misunderstood in traditional behavioral health service organizations. Consequently, treatment attendance and retention remain low. Instead, this population generally seeks mental health services in community organizations for lesbian, gay, bisexual, transgender, and queer (LGBTQ) youth. Unfortunately, these organizations are often unprepared for this clinical challenge. The Behavioral Health-Works (BH-Works) suicide risk management system may offer a potential solution to this problem. BH-Works is an evidence-based, comprehensive youth suicide prevention program. It offers support for policy development, staff training, suicide and behavioral health screening, technology-assisted safety planning, an electronic patient referral system, real-time data analytics for program monitoring, and a learning collaborative structure to support sustainability. All functions are supported on a web-based software platform that facilitates cross-system communication, implementation, adoption, and expansion. In this project, the investigators will adapt this program for LGBTQ organizations and test feasibility, acceptability and preliminary effectiveness. This project builds upon robust partnerships with two diverse LGBTQ organizations in Philadelphia, Pennsylvania and rural Southwest, Virginia) and their respective behavioral health (BH) partnering sites. To facilitate BH-Works adaptation for SGM adolescents, the investigators will employ the Enhancing Engagement trajectory from Lau's cultural adaptation framework. To pilot the program within LGBTQ organizations and their partners, the investigators will use an Effectiveness-Implementation Hybrid Type 2 design with a historical comparison group. Informed by the Consolidated Framework for Implementation Research, the investigators will also pilot test a sequenced implementation strategy. This strategy focuses on promoting engagement, building partnerships, and creating sustainability. In Years 1 and 2, the investigators will collect treatment as usual data, and work with their partners to adapt BH-Works policy, content, practices, and workflow. The investigators will also train staff/providers in suicide risk management, family engagement and affirmative care. In Years 3 and 4, the investigators will test the adapted SGM BH-Works Program and examine several essential program targets (training impact, partnership development, software usability) and outcomes (successful referral, program satisfaction, caregiver involvement, suicide identification). The proposed research responds to the growing national need to identify and refer vulnerable youth at risk for suicide. A future R01 will examine SGM BH-Works program effectiveness with partnering LGBTQ and BH sites across the nation.
The purpose of this study is to evaluate the immunogenicity, safety, and reactogenicity of the RSVPreF3 OA investigational vaccine in an immunocompromised (lung and renal transplant recipients) population and assess whether a second dose of the vaccine increases the immune response.
The purpose of this study is to evaluates how probiotics and dietary supplementation with an herbal powder can shift the gut microbiome in those with non-cystic acne vulgaris.
This research study is being conducted to understand the outcomes of participation in the Up ENDing Parkinson's rock climbing program (24 sessions, or twice per week for about 12 weeks) on walking & mobility, hand strength & dexterity, and psychological well-being in individuals with Parkinson's Disease (PD). The rock climbing sessions are administered and supervised by Up ENDing Parkinson's, and are tailored to the skill level of the participant. Participants will answer questionnaires and complete physical performance tests twice, first prior to beginning the sessions and then again after the 24 sessions have been completed.
This is a LTFU study for thoracic SCI subjects that were administered GRNOPC1 cells in the main study CP35A007.
This is a prospective, multicenter, non-randomized, open label light dose escalation phase I trial to evaluate the safety and preliminary efficacy of Padeliporfin vascular targeted photodynamic therapy (VTP) applied via endovascular fiber placement within a dilatation catheter, through the superior mesenteric artery (SMA) in patients with stage III, locally advanced (LA) unresectable pancreatic ductal adenocarcinoma (PDAC). The investigators will evaluate safety and preliminary efficacy of Padeliporfin VTP administered endovascularly using light dose escalation.
The OLE study aims to investigate the safety, efficacy, pharmacodynamics (PD), pharmacokinetics (PK), and immunogenicity of efgartigimod in participants with post-COVID-19 postural orthostatic.
This study will examine the impact of high-frequency repetitive transcranial magnetic stimulation on food choice behavior and related neural activity.
