Clinical trials

Establishing a sensitive, scalable physiological test for neurovascular reflex integrity and investigating whether targeted peripheral neural stimulation can enhance perfusion and vasodilatory responsiveness.

This study examines a novel way to prevent suicide among Veterans with serious mental illness (SMI). It will assess the efficacy of PREVAIL-VA, a 3-month intervention of 12, one-on-one sessions between a Peer Specialist (PS) and a Veteran that involve semi-structured conversations focused on hope, belongingness, support, and safety. PSs are Veterans with SMI trained to use their own experience and recovery to help other Veterans with SMI. PSs have improved mental health outcomes in other research, but this study would be the first to test their efficacy for suicide prevention in VHA. The project will compare outcomes of Veterans at risk for suicide receiving usual care, to PREVAIL-VA. This work is responsive to national calls for Veterans with SMI to receive support that is evidence-based, improves recovery (not just symptoms), and is tailored to individual needs. If successful, PREVAIL-VA could be adopted by the 1400 Peer Specialists employed in VA, greatly increasing the delivery of evidence-based services to Veterans at risk for suicide.

This is an intent-to-treat, parallel design, multicenter randomized trial and the primary intervention is a double-blind comparison of Imiquimod (IMQ) vs. placebo cream for preventing basal cell carcinoma (BCC) of the skin on the face at one year and over 3 years after therapy. Participants will apply the IMQ or placebo cream to the face daily at bedtime for 12 weeks. This study will recruit 1630 Veterans at high risk of BCC from 17 VA medical centers.

The purpose of this study is to characterize proprioceptive sensations in the missing limb of upper limb amputees using nerve stimulation, and to develop advanced controllers for moving a prosthesis. Proprioceptive sensations are the sensations that tell individuals where their hand is in space, and if it is moving. The research team uses Functional Electrical Stimulation (FES), which involves applying small electric currents to the nerves. These signals are then transferred to the brain just like the information about the individual's intact hand used to be transferred to their brain. This study will test different placements for stimulation and determine which one(s) provide the individual with proprioceptive sensations. The investigators want to know what the participants feel and if the investigators can use proprioceptive sensation to give the participants information about limb movement and position.

Sleep-disordered breathing (SDB or sleep apnea) is very common among elderly Veterans and leads to increased morbidity and mortality in this population. The proposal aims to identity whether oxygen, finasteride and acetazolamide can be effective in reducing unstable breathing and eliminating sleep apnea in the elderly via different mechanisms. This proposal will enhance the investigators' understanding of the pathways that contribute to the development of sleep apnea in the elderly. The investigators expect that the results obtained from this study will positively impact the health of Veterans by identifying new treatment modalities for sleep apnea. A cumulative effect of the investigators' research will fulfill the long-term goal of improving the quality of life of elderly Veterans suffering from sleep apnea and its potential life-threatening complications.

The overall purpose of this study is to develop a power training intervention in partnership with Veterans participating in Gerofit and to evaluate the program's acceptability, feasibility, and preliminary participant outcomes (leg power, physical function and self-report participation).

Empagliflozin, a sodium-glucose co-transporter 2 inhibitor (SGLT2i), is a novel diabetic medication that reduces the risk of progression of chronic kidney disease (CKD) and heart failure and improves exercise tolerance regardless of the diabetes status. One of the important ways that empagliflozin improves health may be through its benefits on blood vessels. The effects of empagliflozin on blood vessels and physical function have not been examined in patients with chronic kidney disease, and it is less clear if empagliflozin may be beneficial in patients with chronic kidney disease without heavy urinary protein leakage. The investigators will examine if empagliflozin can improve blood vessel function and exercise tolerance in Veterans with chronic kidney disease without heavy urinary protein leakage.

In this pragmatic clinical trial, which will dovetail with Veterans' routine outpatient dialysis clinic visits in six VA medical centers, the investigators will study 252 Veterans with kidney disease who need to start dialysis treatment. If a Veteran is eligible for the study by making enough residual urine, he/she will have a 50% chance to be offered the usual three-times-per-week dialysis vs. twice-per-week dialysis that is gradually increased to three-times per- week over one year. The investigators will compare health-related quality of life, how long residual kidney function lasts, and other measures including safety in these two groups. By conducting this study, the investigators hope to understand 1) whether starting dialysis with less frequency is safe, effective, and can help Veterans and their care-partners to better cope with dialysis, and 2) if incremental dialysis can result in major cost benefits to the VA health care system, thus allowing more patients to stay in VA dialysis clinics vs. being transferred to outside clinics.

Providing care to individuals with serious mental illness can be challenging, requiring ongoing monitoring, treatment adjustments, and coordination of various medical and social services. Rates of emergency service and hospital use are high due to unexpected social, medical, and mental health crises. Stressors and poor adherence with treatment are common and can lead to rapid worsening in symptoms, job loss, homelessness, incarceration, or suicide. Clinician visits can be infrequent. Patient-clinician contact between visits is challenging and often nonexistent. As such, illness exacerbations usually occur with no clinician awareness in real time, leaving limited opportunity to provide services. Clinicians need interventions that are capable of monitoring and quickly detecting worsening behaviors and illness, to improve care coordination, outreach, and treatment. This project studies the effectiveness of enhanced care coordination using passive mobile data monitoring and support from peer specialists, with the goal of improving outcomes and reducing the need for acute care.

Many Veterans experience psychological distress including depression, PTSD, anxiety and problems with sleep and anger. Services to address these problems need to be easy for Veterans to access. VA mobile health applications (mHealth apps) that teach skills to manage psychological distress are widely available. However, Veterans rarely use these apps enough to experience health benefits. Peer specialists are VA employees who are trained to use their lived experiences in mental health recovery to help other Veterans. Peers can provide support and accountability to Veterans as they use mHealth apps. Peers working in VA primary care settings are easily accessible to Veterans who receive VA services. This study aims to improve the health of Veterans by testing the effectiveness of peer-supported mHealth in reducing psychological distress. It will also test how much peer support Veterans need to improve their health with using mHealth apps.

Antimicrobial resistance is a major public health concern that worsens healthcare outcomes. Antibiotic resistant organisms occur more often in Veterans with spinal cord injury or disease (SCI/D) given their frequent exposure to antibiotics, recurrent hospitalizations, and common use of urinary catheter devices. Veterans with SCI/D are also at risk for overtreatment with antibiotics when they do not need them, particularly for over-diagnosed urinary tract infections. The investigators plan to create a patient empowerment program with input of Veterans with SCI/D \[and their providers\] to help guide their decisions and next steps when they have a change in bladder symptoms. The program will give Veterans with SCI/D the tools to speak up to their provider and advocate for themselves to avoid receiving unnecessary antibiotics. This program is highly innovative, as it puts Veterans with SCI/D in charge of thoughtful antibiotic use, or antibiotic stewardship.

The VA has been focused on reducing the number of homeless Veterans nationally. However, it has been very difficult to increase the level of productive activities--including work, school, and training--for homeless-experienced Veterans (HEVs), even when the VA provides substantial case management and support services in addition to housing. The overarching aim of this proposed treatment project is to validate an innovative psychosocial intervention (a combination of Motivational Interviewing and Cognitive Behavioral Therapy; MI-CBT) that is designed to enhance motivation and increase productive community integration in Veterans who have experienced homelessness. The efficacy of this new intervention will be evaluated in a randomized control trial that includes 24 weeks of active treatment, and a follow up assessment, compared with a control condition. The results of the proposed study will have clinical and functional impact for Veterans by helping HEVs to achieve fuller community integration.

Over 60% of Veterans with serious mental illness have a service-connected disability that impairs their ability to work, go to school, and/or have successful personal lives. Although traditional treatments tend to focus on symptom remission, Veterans prioritize a range of treatment goals, including personal empowerment and gaining personally meaningful skills. Increasing Veteran-clinician collaboration can help effectively align care with each Veteran's goals and support an empowering therapeutic experience. This project will evaluate the effectiveness of a group-based intervention intended to increase Veterans' comfort, confidence, knowledge, and skills to collaborate with their treatment teams. Findings from this study will contribute important knowledge about this intervention's effectiveness and how to enhance its effectiveness, especially for Veterans from minoritized groups. If the decision-making intervention is effective, it would help Veterans with serious mental illness, and might also help Veterans with other chronic health conditions, like PTSD and chronic pain.

Despite the availability of evidence-based treatments for post-traumatic stress disorder (PTSD), there are many challenges to successful trauma recovery for Veterans including difficulties starting and completing these treatments and gaps in fully addressing additional important treatment targets including lower social functioning and quality of life. Alternative, stand-alone treatment options that address a range of outcomes and can be easily accessed are needed to expand the reach of PTSD treatment to Veterans. One way to address this need is with a positive psychology intervention called MOVED, which has shown promise in a prior pilot study. MOVED is a web-based, self-guided intervention (8 sessions, 4 weeks) that uses moral elevation-feeling inspired by others' virtuous actions. This clinical trial will test if MOVED leads to decreased PTSD symptoms and increased social functioning and quality of life compared to a generic supportive treatment that does not focus on moral elevation. Results will help determine if MOVED is a useful alternative approach to target trauma recovery among Veterans with PTSD.

The project will investigate the efficacy of a Veteran-peer-navigator-led decision coaching (PDC) program to promote Shared Decision Making (SDM) for prostate cancer screening among Veterans at the Veterans Health Administration (VA). Prostate cancer is commonly screen detected using PSA, a non-specific test which has led to modest population-level survival benefits at the cost of over-detection of low-risk disease. This trade off in outcomes is ideally addressed using SDM which can be challenging to implement in time constrained primary care office visits. The investigators propose the evaluation of a PDC intervention to promote SDM for PSA screening to improve both access and quality of care for Veterans. The investigators results will enhance understanding of the efficacy, cost-effectiveness, and sustainability of PDC interventions for SDM promotion across communication formats in the VA. Lessons learned through this proposal will not only improve quality of care for PSA screening but also will suggest a paradigm for dissemination of SDM across preventive services.

Social isolation is a negative social determinant of health that affects 1-in-5 adults in the U.S. and 43% of Veterans. Social isolation is estimated to cost the nation $6.7 billion annually in federal healthcare spending. Yet, social isolation has rarely been the direct focus of healthcare interventions. The proposed project is a randomized controlled trial that seeks to test the effectiveness of the Increasing Veterans' Social Engagement and Connectedness (CONNECTED) intervention on social isolation among diverse Veteran groups in primary care clinics. Increasing Veterans' Social Engagement and Connectedness involves three key services delivered by peers via telehealth through individual and group sessions over 8 weeks: 1) peer support, which includes person-centered assessment for social isolation, 2) psychosocial interventions to address social isolation, and 3) navigation (i.e., connecting Veterans to social resources). Findings from this study will contribute to the VA's efforts to address social determinants of health among Veterans and to provide high quality, person-centered, and equitable care to all Veterans.

The VA wants to understand what type of integrative and whole health approaches are helpful for Veterans. The study is comparing two primary care based mental health treatments, a mindfulness class that teaches mindfulness meditation and a problem-solving class that teaches problem-solving skills and how to build resilience, for Veterans who are experiencing symptoms of anxiety, depression, and/or PTSD. The goal of the study is to understand if the classes reduce symptoms of anxiety, depression, and/or PTSD and increase overall functioning.

Many veterans with Gulf War Illness developed chronic gastrointestinal symptoms during their deployment to the Persian Gulf. The pathophysiologic mechanisms of these chronic gastrointestinal symptoms are not well understood but cause significant morbidity in veterans. Our proposed studies will provide an innovative and novel treatment trial for chronic gastrointestinal symptoms in veterans with Gulf War Illness that were deployed into war zones. Given that there are currently no specific treatments for these disorders, and that current symptomatic approaches are far from ideal, proof of principle of our trial would be an extremely important advance as it would not only have a beneficial impact on the health of many thousands of our veterans, but also it would substantially reduce the many negative economic effects of this ailment on the VA Health Care System.

Posttraumatic stress disorder (PTSD) is frequently accompanied by difficulty concentrating, poor memory, and inability to keep up with tasks, which negatively impacts a person's ability to function at work and in relationships. Currently available treatments do not fully relieve all symptoms. A published research report showed positive evidence that the stimulant medication methylphenidate was beneficial in treating these problems. This study will evaluate the ability of methylphenidate to treat PTSD and associated neurocognitive complaints in Veterans. An innovative feature is the study's N-of-1 design. In this design, every participant will move back and forth every 4-5 weeks between treatment with methylphenidate and treatment with placebo, in random order and under double-blind conditions, over a 20-week period. The investigators will compare the aggregated change in PTSD and neurocognitive symptoms between periods of treatment with methylphenidate versus placebo. Results will help clinicians to better choose the best treatment for Veterans living with PTSD.

The proposed study will test a novel treatment for alcohol use disorders (AUD) to determine if it helps Veterans reduce their hazardous drinking and recover from alcohol-related functional impairments across social, occupational, and domestic domains. To do so, the investigators will evaluate clinical, cognitive, and neural effects of a computer-delivered Approach Avoidance Training (AAT) treatment - which changes implicit tendencies to approach alcohol-related cues - in conjunction with standard VA care. The project will support RR\&D's mission to improve Veterans' participation in their lives and community by determining if this innovative alternative technique can improve recovery outcomes for Veterans with AUD and exploring how the intervention works.

Cognitive processing therapy (CPT) and prolonged exposure therapy (PE) were widely disseminated as recommended posttraumatic stress disorder (PTSD) treatments. However, post-9/11 Veterans with PTSD rarely initiate CPT or PE, especially as an initial treatment. Little research has explored the combinations and sequences of psychosocial and medication treatments that Veterans receive ("treatment sequences"). One common and understudied treatment sequence begins with stabilization treatment, which is designed to prepare Veterans for CPT or PE. There is a significant research gap in understanding how treatment sequence affects initiation of CPT or PE. The proposed research is an innovative, mixed-methods approach to assessing the impact of variability in treatment sequence, including stabilization treatment, on initiation of CPT or PE and applying this knowledge by developing a health services intervention that facilitates timely transition to CPT or PE. Research aims can improve PTSD treatment by increasing initiation of and reducing disparities in CPT/PE.

Patients with Parkinson's disease (PD) sometimes experience symptoms affecting their movement, such as slowness, tremor, stiffness, and balance or walking problems. Many patients also have other symptoms not related to movement, called non-motor symptoms, which may affect one's mood or emotions, memory or thinking, or cause one to see or hear things that aren't real (hallucinations) or believe things that aren't true (delusions). Hallucinations or delusions, together called psychosis, occur in up to 60% of PD patients at some point in time. Parkinson's disease psychosis can sometimes be associated with decreased quality of life, increased nursing home placement, increased rate of death, and greater caregiver burden. There are approximately 50,000 Veterans with Parkinson's disease receiving care in the VA, and up to 30,000 (60%) of them will experience psychosis at some point in time. Quetiapine is an antipsychotic drug approved by the Food and Drug Administration (FDA) that is the most commonly used medication to treat PD psychosis, but more studies are needed to determine if it works for this condition and is also well tolerated and safe. Pimavanserin is a newer antipsychotic drug approved by the Food and Drug Administration (FDA) specifically to treat PD psychosis, but more studies are needed to determine if it works and its safety. The purpose of this research is to gather additional information on the safety and effectiveness of both Quetiapine and Pimavanserin. By doing this study, the investigators hope to learn which of these medications is the most effective course of treatment for people with PD psychosis. Enrollment is open to Veterans nationwide, see your VA provider about the possibility of being referred to one of the study's Hub sites. This can be done through contact from your provider to the study's NSC (Tamara Boney at 267-303-9829).

Opioid Use Disorder (OUD) is a complex, chronic condition affecting nearly 70,000 Veterans who can experience significantly reduced quality of life (e.g., poorer social, occupational, and health-related functioning). VA clinics providing Medication treatment for OUD (MOUD); e.g., buprenorphine, methadone), the 1st-line treatment for OUD, often face challenges in also attempting to treat Veteran functional needs, which may require them to extend beyond their available resources to provide support. There is an urgent need for functionally impactful and accessible treatments for Veterans in MOUD. Acceptance and Commitment Therapy (ACT) is a well-suited framework to support the functioning of Veterans in MOUD with over 20 years of research support. However, the traditional practice ACT requires a trained clinician to provide weekly, hour-long therapy sessions (typically for 12-16 weeks) and may be too burdensome for MOUD clinics to use alongside standard care. Fortunately, emerging research suggests that mobile health interventions (MHIs; e.g., smartphone apps) can overcome many of these pragmatic barriers. MHIs can efficiently deliver functionally-focused treatments focused on Veteran functioning in "real-world" settings, through minimally burdensome and accessible formats. Currently however, no MHI's targeting functioning exist for Veterans in MOUD. The proposed study will address this gap by developing and evaluating an early prototype of a targeted smartphone app designed to enhance the functional outcomes of Veterans receiving MOUD called "ACT to RECOVER" (Acceptance and Commitment Therapy to Reach Empowerment through Commitment, Openness, and Valuing Experiences in Recovery). The study will occur in 3 phases: Phase 1: Development. Develop content for ACT to RECOVER using Veteran (n=10) and provider feedback (n=10). Phase 2: Iterative Usability Assessment. Conduct field testing (3 rounds, n=4-5 per round) to refine ACT to RECOVER format, acceptability, and usability. Phase 3: Pilot ACT to RECOVER in a Stage 1b Randomized Controlled Trial (RCT). Conduct a pilot trial to compare ACT to RECOVER (n=20) to a smartphone-based symptom monitoring control group (n=20). * (3a) Evaluate the acceptability and feasibility of each condition's app and study procedures. * (3b) Explore changes in functional (e.g., values-based living, quality of life) and clinical outcomes (e.g., illicit opioid use) which will be key outcomes in future efficacy testing.

Long-term above-knee prosthesis users are at an increased risk of developing secondary musculoskeletal conditions compared to the general able-bodied population. One secondary physical concern is low back pain (LBP), for which the development is not entirely understood, but in above-knee prosthesis users it is believed to relate to asymmetries and compensations that are typically demonstrated and required to stand and walk. Understanding spinal motion and compensations will enhance our knowledge of the factors contributing to LBP, and possibly lead to the development of new prosthetic and therapeutic interventions to prevent or alleviate LBP, thereby improving mobility and quality of life for prosthesis users.

The purpose of this multi-site randomized controlled trial is to evaluate the efficacy and risks of psilocybin for the treatment of depression in U.S. military Veterans with and without (±) concurrent posttraumatic stress disorder.
