Streptococcus pneumoniae, commonly called pneumococcus, can cause a wide range of diseases in children from mild ear infections to deadly pneumonia or meningitis. Vaccination is currently the single best way to protect children. Nutrition, especially the amount of vitamin A, may play a role in how well your body responds to infection or a vaccine. We call this an immune response. This research will look to see if children who take a vitamin with their vaccine have a better immune response than children who do not take a vitamin with their vaccine. Primary Objective To evaluate the influence of vitamin A supplementation on Prevnar vaccine immunogenicity based on changes in antibody scores in a commercial ELISA at Day 21 (after a booster vaccine dose) compared to pre-vaccine values. Secondary Objectives * To evaluate the relationship between baseline vitamin levels and pneumococcal or hepatitis A vaccine antibody responses (based on in commercial ELISAs) at Days 0 and 21. * To evaluate the influence of vitamin A supplementation on hepatitis vaccine immunogenicity based on changes in antibody scores in a commercial ELISA at Day 21 compared to pre-vaccine values. * To evaluate relationships between total serum antibodies (based on individual IgM, IgG1, IgG2, IgG3, IgG4, and IgA scores in a Luminex assay) at Day 0 and changes between Days 0 and 21 with baseline (Day 0) vitamin levels in young children, and with vitamin A supplementation.

The main objective of this randomized controlled trial (RCT) is to investigate whether a multimodal prehabilitation intervention combining a mixed-nutrient supplement with structured exercise training (MM) or the supplement alone (NUT), against a placebo (CTRL), leads to improvement in functional capacity and postoperative outcomes in surgical patients with lung cancer, at nutritional risk. This will be tested in a single centre RCT of 3 parallel arms, double-blinded for the supplement. Female and male participants (n=168, \>=45 y) will be randomized to a 10-week intervention spanning 4 weeks pre-surgery and 6 weeks post-hospital discharge. The primary outcome is functional capacity as measured by the 6-minute walk test. Secondary outcomes include muscle mass, quality and strength, quality of life, length of hospital stay, and postoperative complications.

This study investigates how orally ingested exogenous ketone monoester supplements affect circulating hormone concentrations in healthy young adult males after a single session of resistance exercise. Resistance exercise is known to stimulate an acute increase in the circulating concentration of various hormones that are involved in the regulation of muscle mass, including testosterone, growth hormone (GH), and insulin-like growth factor-1 (IGF-1). Recently, there has been growing interest in how nutritional supplements impact these natural hormone responses at rest. One such intervention is the oral ingestion of exogenous ketone body supplements. Ketone bodies (i.e., β-hydroxybutyrate (β-HB), acetoacetate (AcAc), and acetone) are naturally occurring compounds that are normally produced by the body during prolonged fasting/starvation, or in response to a "ketogenic" diet (a diet very high in fat and very low in carbohydrates). These ketone body supplements taken in the form of a ketone monoester can quickly raise blood ketone levels without needing to change your diet. Recent research has shown that the ingestion of exogenous ketone supplements or following a 'ketogenic diet' can alter the concentration of certain hormones measured in blood samples at rest. However, the effects of ketone monoester intake on the exercise-induced elevation in circulating hormones is yet to be explored. Therefore, the purpose of this study is to examine how elevated β-HB, induced via the ingestion of the ketone monoester (R)-3-hydroxybutyl-(R)-3-hydroxybutyrate, affects blood concentrations of various anabolic hormones, during post-exercise recovery in healthy young adult males, compared to a placebo drink (flavoured water).

Broccoli Extract for Alcoholism

New Orleans, Louisiana
Chronic alcohol consumption leads to perturbations in gut microbiome balance (dysbiosis) and disruption of gut barrier integrity. As a result, bacteria, toxins, and metabolites can enter the blood stream and reach distant organs, triggering inflammation and oxidative stress. Through this mechanism gut leak is closely related to the onset of metabolic diseases, such as nonalcoholic fatty liver disease (NAFLD) and diabetes. Despite the prominent role of diet and alcohol in the pathogenesis of metabolic diseases, there is a lack of treatments to mitigate their effects in triggering systemic inflammation and oxidative stress. Novel treatments using generally recognized as safe (GRAS) compounds focused on restoring the intestinal barrier to mitigate metabolite endotoxemia are sorely needed. This project will test the potential of broccoli sprouts extract (BSE) as a GRAS treatment to minimize the combined effect of poor nutrition and alcohol on the gut. Broccoli sprouts are rich in sulforaphane, a bioactive compound derived from the glucosinolate glucoraphanin with anti-inflammatory and antioxidant proprieties. BSE supplementation has been used in preclinical and clinical studies as a health- promoting food, showing significant positive changes in the gut microbiota composition, protection against colitis, cardiometabolic improvement, and lower inflammation. We believe that BSE is a viable alternative therapeutic approach for patients who are resistant to lifestyle changes such as healthy eating and reducing alcohol use. Our purpose is to test BSE supplementation in human subjects with poor nutrition compounded by alcohol use, specifically in older adults who we believe will receive greater benefit from this approach. At the completion of the proposed study, we expect to have determined that treatments using generally recognized as safe (GRAS) compounds can be useful to restore the gut barrier integrity, and as consequence of reduced gut leak we expect to observe lower inflammation and oxidative stress.

Supplement for Hunger

Fort Worth, Texas
Study Summary The goal of this study is to understand whether a dietary supplement containing L-arginine, resveratrol, tart cherry, and vitamin C reduces hunger and increases the release of GLP-1, a hormone associated with appetite suppression and improved glucose regulation. The study will also explore the metabolic effects of the supplement. Main Questions: 1. Does the supplement reduce hunger more effectively than a placebo? 2. Does it enhance GLP-1 release in individuals with overweight or obesity? Participants: * Age: 18-60 years * Body Mass Index (BMI): 25-40 kg/m² * Total participants: 25 * Must maintain usual eating and activity habits during the study. Study Design: * Conditions Tested: High-dose supplement, low-dose supplement, and placebo. * Participants will undergo three separate 2-hour lab visits, each after fasting for 8 hours. * During each visit: * Consume the assigned supplement or placebo. * Eat a standardized meal after a 60-minute rest. * Provide blood samples at eight time points to measure GLP-1 and other metabolic markers. * Rate hunger using a 7-point scale. Benefits and Risks: * Benefits: Participants may not directly benefit, but the findings could lead to new appetite-suppressing supplements that aid in weight loss. * Risks: Include discomfort from blood draws, possible gastrointestinal side effects from the supplement, and allergic reactions. Measures are in place to minimize these risks, such as pre-screening for allergies and using trained personnel for blood collection. This study is triple-blinded, meaning neither the participants, researchers, nor analysts will know which condition is being tested during each visit. Data collected will be anonymized to protect participant privacy.

Concussions affect thousands of Canadians every year. Although the effects are usually temporary, 10-15% of adults experience persistent symptoms likely to last several weeks or even months. It is suggested that nutritional interventions should be considered in concussion management because nutrition can act on several mechanisms of brain injury. However, to date, no study has assessed the impact of dietary interventions on the recovery of people with persistent post-concussive symptoms. This randomized controlled trial aims to determine the impact of a dietary and nutritional intervention on the physical, cognitive, behavioural and emotional symptoms of patients with persistent post-concussive symptoms in New Brunswick, Canada. Patients will be randomized to one of three groups: 1) dietary treatments and nutritional supplements (experimental group A), 2) nutritional supplements (experimental group B), and 3) physiotherapy treatments (control group). Patients in group A will receive four consultations with a dietitian over eight weeks, in addition to conventional physiotherapy treatments. These patients will receive nutritional counselling and omega-3, vitamin D and creatine supplements. Patients in group B will be prescribed the same supplements as those in group A by their doctor and receive physiotherapy treatments. Finally, patients in the control group will only receive physiotherapy treatments. Patient symptoms will be measured using a questionnaire constructed from tools commonly used in practice. This questionnaire will be completed at the first physiotherapy session and 2, 4 and 8 weeks after the start of the intervention.

"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."

Probiotics for Obesity

Los Angeles, California
The current standard of care for obesity is the optimal management of comorbid conditions such as diabetes and hyperlipidemia, and counseling on diet, weight loss, or increased physical activity programs. However, lifestyle, diet, and behavioral interventions may provide between 7-10% reduction in initial weight and even fewer with long-term weight loss. In severely obese patients (BMI\>40 or BMI\>35 with comorbidities), bariatric surgery is also a potential treatment, but there is a high barrier for patients to undergo surgery for weight loss. These barriers include an aversion to major abdominal surgery, long recovery time, potential risk of vitamin deficiency, and risk for abdominal pain. For these reasons, there is a paramount need for other treatments for obesity and for food addiction. The current standard of care for obesity and food addiction is difficult to implement and lacks sustained efficacy. Most struggle to complete treatment, lose minimal weight, lack sustained weight loss, and engage in the well-known "YoYo" diet phenomenon. While bariatric surgery is currently the only effective treatment for obesity, there are several barriers associated with it such as eligibility requirements, invasiveness, difficult recovery, and cost making it not readily available for everyone. Some approved medications that help with obesity, such as orlistat, lorcaserin, or naltrexone-bupropion, have not been widely adopted by providers or patients due to their limited responses and adverse side effects. Probiotic cocktails have shown to be safe with little to no side effects. Preclinical models of probiotics demonstrate the ability to curb obesity in animal models. Therefore, a probiotic that is able to show significant weight loss along with lifestyle modifications would be highly adopted and desirable.

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.
