SMART Exercise for Peripheral Arterial Disease

Chicago, Illinois
Supervised exercise therapy (SET), consisting of treadmill exercise conducted three times weekly at a center while supervised by healthcare personnel, is first line therapy for people disabled by lower extremity peripheral artery disease (PAD). However, travelling three times/week to a center for SET is burdensome. Compared to SET, home-based exercise is more accessible and less burdensome. Yet, evidence-based guidelines recommend SET over home-based exercise for PAD. Walking exercise is first line therapy to improve walking distance for PAD, but it does not eliminate ischemic leg symptoms in most people with PAD. The investigators' work and that of others showed that nitrate-rich beetroot juice, which increases plasma nitrite, limb perfusion, and skeletal muscle function, significantly improved exercise tolerance and reduced non-response to exercise in people with and without PAD. The investigators will use a 2 x 2 factorial design to address two major barriers to achieving benefits from exercise therapy for PAD: First, guideline recommendations for supervised exercise therapy (SET) as first line therapy for PAD. Second, the inability of exercise therapy to eliminate PAD-related disability in most people with PAD. Participants will be randomized to one of four groups for 12 weeks: Supervised treadmill exercise + nitrate rich beetroot juice; supervised treadmill exercise + placebo, home-based walking exercise + nitrate rich beetroot juice, home-based walking exercise + placebo.

Fisetin for PAD

Chicago, Illinois
The investigators propose a pilot randomized trial to gather preliminary data to test the hypothesis that Fisetin will reduce abundance of senescent cells in blood, skeletal muscle, and both subcutaneous and inter muscular adipose tissue and improve 6-minute walk distance in 34 people with peripheral artery disease (PAD). the investigators will determine whether greater declines in abundance of cells with senescent markers are associated with greater improvement in 6-minute walk distance in people with peripheral artery disease. In exploratory analyses, the investigators will assess whether Fisetin reduces interleukin-6 (IL-6) and novel senescent markers in adipose tissue, muscle, and/or blood.

Blood Pressure Treatment for High Blood Pressure

Nashville, Tennessee
Hypertension is a common and treatable disorder that remains the leading preventable cause of heart disease. Blood pressure treatment relies mainly on upper arm blood pressure readings and ignores blood vessel physiology and underlying individual genetic information. Older Veterans with hypertension are less likely to be treated to goal blood pressure because there are conflicting recommendations for what constitutes "optimal" in older adults. The investigators have developed a novel way to non-invasively assess the components of blood vessel stiffness that is related to blood pressure (load-dependent stiffness). This project will generate new knowledge about how different blood pressure treatment goals (intensive vs standard) impact different components of arterial stiffness and if these differences can be explained through genetic analysis. Results from this project will offer the VA an updated blueprint for personalizing blood pressure care in older adults, ultimately improving cardiovascular health.

Probiotics for Vascular Aging

Milwaukee, Wisconsin
Emerging data suggest the gut microbiota regulates multiple mechanisms related to vascular aging, but no intervention targeting the gut microbiota has been tested in older adults without cardiovascular risk factors or cardiovascular disease. Early human data suggest an increase in potentially pathological gut metabolites such as trimethylamine-N-oxide (TMAO) are associated with older age, increased vascular stiffness, increased oxidative stress, and reduced nitric oxide (NO) bioavailability as evidenced by impaired endothelium-dependent vasodilation. Based on this data, the investigators hypothesize that supplementation with Lp299v will reverse human vascular aging in healthy older adults free of known traditional cardiovascular risk factors.

Acetate Supplements for Age-Related Vascular Stiffness

Aurora, Colorado
Cardiovascular diseases are the leading cause of morbidity and mortality and contribute most to healthcare costs in the U.S. Age is the strongest cardiovascular disease risk factor, with \>90% of all deaths from cardiovascular disease occurring in adults \>50 years old. The age-associated increased risk of cardiovascular disease is due, in large part, to the development of arterial dysfunction, including endothelial dysfunction and stiffening of the large elastic arteries. Therefore, novel, effective interventions that improve arterial function will have a large public health impact by decreasing the risk of cardiovascular diseases. The short-chain fatty acid acetate is endogenously produced by the gut microbiome from fermentation of dietary soluble fiber. High-fiber diets reduce risk of cardiovascular diseases, but unfortunately, a low percentage of Americans meet guidelines for adequate dietary fiber intake and, despite nationwide efforts to improve this, trends in fiber intake have not improved over the last 20+ years. Thus, directly supplementing acetate may be a more practical and feasible intervention for effectively improving arterial function in older adults and reducing the risk of cardiovascular diseases. The investigators will conduct a study to determine the efficacy of 12 weeks of oral supplementation with acetate for improving arterial function in late middle-aged and older (50+ years) adults. They will also assess the safety and tolerability of acetate supplementation in these adults and perform innovative mechanistic analyses to determine how acetate supplementation improves arterial function. The investigators hypothesize that oral acetate supplementation will improve arterial function by decreasing oxidative stress and increasing nitric oxide bioavailability, and also hypothesize that acetate supplementation will be safe and promote high rates of adherence.

MitoQ + Exercise for Menopause-Related Vascular Health

Aurora, Colorado
This trial tests whether combining moderate aerobic exercise with the antioxidant MitoQ can improve blood vessel function in postmenopausal women who lack estrogen. MitoQ aims to reduce oxidative stress and enhance blood flow by improving mitochondrial function. The study will compare the effects of exercise with MitoQ, exercise alone, and MitoQ alone. MitoQ is a mitochondria-targeted antioxidant that has been studied for its potential to enhance exercise-induced muscle adaptations and improve peak power in untrained middle-aged men.

Aerobic Exercise for Vascular Health

Aurora, Colorado
The goal of the proposed study is to understand the reasons for the variability in aerobic exercise (AE) training benefits on the vasculature in middle-age and older (MA/O) adults, including differences between men and women. To achieve this goal, a mechanistic randomized controlled (RCT) will be conducted, in which adults are randomized to 12-weeks intervention of AE or no-exercise Control. Our overall hypothesis is that the exercise response variation in vascular benefits is related to age and sex differences in the biological changes underlying vascular aging and/or the molecular transducers (i.e., circulating molecules) that communicate and coordinate the effects of AE on the vasculature in the periphery and brain. Because this is a mechanistic trial, the overall goal is not a single health-related outcome. Rather, the goal is to advance our understanding of the molecular signals and pathways underlying the systemic and local effects of AE on vascular health that may explain the variability in AE responses with age and sex. This knowledge will allow for the development of personalized age- and sex-specific AE recommendations, and/or provide insights into molecular targets that can be manipulated to enhance and/or mimic exercise in non-responders or in persons unable to exercise.

Estradiol Patch for Menopause

Aurora, Colorado
The menopause transition is associated with a decrease in artery health and an increased risk for weight gain in storing fat in the stomach area which may increase the risk for heart disease. The purpose of this research is to study how the decrease in estrogen at menopause changes artery health and fat gain, and risk of disease in women as they age. The first aim in this study will determine whether short term and long term low estrogen levels in premenopausal women decreases artery function and whether this is related to an increase in fat in the stomach area. The second aim will determine whether the changes in artery health and body fat are related to changes in a pathway that breaks down an important amino acid called tryptophan. This pathway is thought to play a role in regulating the aging process. Therefore, the investigators will determine whether the decrease in artery health and the increase in body fat in the stomach region with low estrogen is related to changes in this pathway in the blood, in vascular cells and fat tissue. Because estrogen levels fluctuate in premenopausal women, the investigators will use an approach (intervention) that controls estrogen levels to address these aims. The investigators will use a medication that is typically used to treat endometriosis or uterine fibroids to lower estrogen levels and an estrogen patch to increase estrogen in some women. Some women will receive a patch that has no estrogen (called a placebo patch). The intervention period will be 20 weeks. The study will provide us with new knowledge on how low estrogen with menopause affects artery health and fat gain estrogen.

Blueberries for High Blood Pressure

Fort Collins, Colorado
Cardiovascular disease (CVD) is the leading cause of morbidity and mortality worldwide. Aging is the primary risk factor for CVD, in large part due to adverse modifications to the arteries. These modifications include vascular endothelial dysfunction and arterial stiffness. Vascular endothelial dysfunction is an initiating step in atherosclerosis, and is primarily caused by reduced nitric oxide (NO) bioavailability secondary to excessive superoxide-driven oxidative stress and inflammation. Endothelial dysfunction leads to arterial stiffness and the development of hypertension (HTN) which further increases CVD. Greater than 2/3 of the US population has elevated blood pressure or stage 1-HTN. As such, interventions that improve vascular endothelial dysfunction by increasing NO bioavailability and mitigating excessive oxidative stress and inflammation are needed. Blueberries are rich in bioactive compounds including flavonoids, phenolic acids, and pterostilbene. These compounds and their metabolites have been shown to attenuate oxidative stress and inflammation. The primary goal of this study is to assess the efficacy of blueberries to improve reduce blood pressure and improve vascular endothelial dysfunction and arterial stiffness in middle-aged/older men with elevated blood pressure or stage 1-HTN.

Antioxidants for Vascular and Muscle Health During Inactivity

Salt Lake City, Utah
Prolonged periods of reduced activity are associated with decreased vascular function and muscle atrophy. Physical inactivity due to acute hospitalization is also associated with impaired recovery, hospital readmission, and increased mortality. Older adults are a particularly vulnerable population as functional (vascular and skeletal muscle mitochondrial dysfunction) and structural deficits (loss in muscle mass leading to a reduction in strength) are a consequence of the aging process. The combination of inactivity and aging poses an added health threat to these individuals by accelerating the negative impact on vascular and skeletal muscle function and dysfunction. The underlying factors leading to vascular and skeletal muscle dysfunction are unknown, but have been linked to increases in oxidative stress. Additionally, there is a lack of understanding of how vascular function is impacted by inactivity in humans and how these changes are related to skeletal muscle function. It is our goal to investigate the mechanisms that contribute to disuse muscle atrophy and vascular dysfunction in order to diminish their negative impact, and preserve vascular and skeletal muscle function across all the lifespan.

Why Other Patients Applied

"I have dealt with voice and vocal fold issues related to paralysis for over 12 years. This problem has negatively impacted virtually every facet of my life. I am an otherwise healthy 48 year old married father of 3 living. My youngest daughter is 12 and has never heard my real voice. I am now having breathing issues related to the paralysis as well as trouble swallowing some liquids. In my research I have seen some recent trials focused on helping people like me."

"I was diagnosed with stage 4 pancreatic cancer three months ago, metastatic to my liver, and I have been receiving and responding well to chemotherapy. My blood work revealed that my tumor markers have gone from 2600 in the beginning to 173 as of now, even with the delay in treatment, they are not going up. CT Scans reveal they have been shrinking as well. However, chemo is seriously deteriorating my body. I have 4 more treatments to go in this 12 treatment cycle. I am just interested in learning about my other options, if any are available to me."

Frequently Asked Questions

How much do Vascular Aging clinical trials pay?

Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.

How do Vascular Aging clinical trials work?

After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Vascular Aging trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length for Vascular Aging is 12 months.

How do I participate in a study as a "healthy volunteer"?

Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.

What does the "phase" of a clinical trial mean?

The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.

Do I need to be insured to participate in a Vascular Aging medical study?

Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.

What are the newest Vascular Aging clinical trials?

Most recently, we added NightWare for PTSD, Aerobic Exercise for Vascular Health and Blood Pressure Treatment for High Blood Pressure to the Power online platform.
