Breakthrough Medication
It is projected that by 2030, one in every five Americans will be of retirement age, and this demographic shift is expected to result in more people suffering from dementia. A key feature of the brain is its need for a constant supply of glucose and oxygen to meet the high energy costs of mental activity. This study aims to develop clinically practical, noninvasive imaging methods based on combined positron emission tomography and magnetic resonance imaging to assess brain energy in order to better understand how this critical component of brain health is impacted by aging.

Prebiotics for Gut Health

Chicago, Illinois
According to International Scientific Association for Probiotics and Prebiotics (ISAPP), a prebiotic is defined as a substrate that is selectively utilized by host microorganisms conferring a health benefit (Gibson et al, 2017). Fibers/ Prebiotics are known to have several beneficial effects on human health via gut. They remain mostly undigested in upper GI and reach colon where they are fermented by resident gut microbiota. This leads to the production of several beneficial metabolites such as short chain fatty acids and others which are implied in human health. The aim of this study is to examine the effects of combinations of two prebiotics on gut microbiota modulation and Quality of Life at two doses.

This study aims to show how digestive enzyme supplements help the body break down fats, proteins, and carbohydrates, especially after eating a high-fat, high-protein meal. Digestive enzymes are essential for nutrient absorption, but some people-such as those with certain medical conditions or high-protein diets-may not produce enough on their own. Poor digestion can lead to bloating, discomfort, and gut imbalances. This clinical trial tests a delayed-release, porcine-derived enzyme blend to see if it improves digestion and reduces symptoms like bloating and gas after eating a high-fat and high protein meal.

Old age, obesity, physical inactivity, environmental factors and genetics may contribute negatively to fertility in both males and females. In males, specifically, certain supplements, such as single antioxidants and trace minerals, have previously been shown to improve sperm function marginally. One hypothesis is that sperm function can be improved even further by combining several different types of supplements (e.g., amino acids, energy carriers, vitamins, antioxidants, and trace minerals) to target several age-related cell pathways, for example, oxidative stress, mitochondrial dysfunction, inflammation and cell energetics. This 3-month placebo-controlled, randomized clinical trial, aims to test the effects of a novel multi-ingredient supplement (Fertility Enhancer) that targets several age-related cell pathways on sperm function in overweight or obese and subfertile males.

The carbohydrate inulin (from chicory root) is a healthy prebiotic ingredient found in dietary supplements and fortified foods (Nagy et al). Inulin is representative of a broader class of typically health-associated, yet fermentable carbohydrates called fructans that occur naturally in many vegetables, fruits, and wheat. Fructans, or long chains of fructose units, are resistant to human digestive enzyme hydrolysis and transit intact to the small intestine and colon where they undergo rapid fermentation by intestinal microbes. This microbial metabolism of fructans produces gas and other fermentation byproducts that can lead to excess gastrointestinal (GI) symptoms like abdominal bloating, cramping, stomach rumbling, and flatulence (Bonnema et al; Briet et al; Bruhwyler et al), especially in individuals with irritable bowel syndrome (Van den Houte et al). A new digestive enzyme called fructanase was developed to help with GI symptoms associated with fructan consumption. Positive findings from in vitro digestion simulations (Guice et al) and a first-in-human safety trial (Garvey et al) helped define the fructanase dose for this clinical trial-the primary objective of which is to investigate the effect of oral fructanase administration on GI symptoms in healthy adults after consuming oatmeal with added inulin (25 grams). Secondary outcomes include breath hydrogen and methane levels, which serve as biomarkers of intestinal microbial fermentation. The investigators hypothesize that fructanase administration will lower the severity of GI symptoms after inulin consumption, as well as lower breath biomarkers of intestinal microbial fermentation, compared to placebo.

Background: At least 30% of Americans have fatty liver disease. This means that they store too much fat in the liver. At the moment lifestyle changes are the only way to treat this problem. Objective: To test how (1) a low-carbohydrate diet and (2) a supplement called nicotinamide riboside (NR) affect how a person s body uses dietary fat. Eligibility: Men aged 18 to 65 and women aged 18 to 50 who are healthy volunteers with a body mass index (height to weight ratio) of 25 or more. Adults with maturity-onset diabetes of the young type 2 (MODY2) are also needed. Design: Participants with diabetes will have 1 screening visit and a 9-day clinic stay. Healthy volunteers will have 1 screening visit and 2 clinic stays of 1 to 2 weeks each. During screening, all participants will have a physical exam with blood and urine tests. They will have their heart rhythm measured while riding a gym bike. NR is a pill taken by mouth. Only healthy volunteers will take the NR, for 14 days at a time, during 1 clinic stay. During their other stay, they will take placebos; these are pills that look like the study supplement but contain no NR. During each clinic stay, all participants will eat a normal American diet. Then they will eat a ketogenic "low-carb" diet for 5 days. Participants will have many tests, including: Sleeping every night and having two 24-hour stays in a special room that measures the gases their body uses and produces. Drinking a high-fat shake, then remaining seated for 5 hours while their blood and breath are monitored. Having a substance injected into the arm and remaining seated for 3 hours while their blood is measured. Wearing monitors to measure their activity levels. Another monitor will measure their blood glucose levels. Having imaging scans. ...

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 Supplements 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 Supplements 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 Supplements 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 Supplements 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 Supplements 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 Supplements clinical trials?

Most recently, we added Quercetin for Microvascular Health, Iron Supplements for Iron Deficiency and Ketone Supplement for Alcohol Withdrawal to the Power online platform.
