Pittsburgh, Pennsylvania
The goal of the NANO trial is to study the longstanding clinical practice of empirically administering intravenous antibiotics to extremely low birthweight (ELBW) infants in the first days of life. In this 802-subject multicenter placebo-controlled randomized clinical trial, the hypothesis to be tested is that the incidence of adverse outcomes is higher in babies receiving empiric antibiotics (EA) in the first week of life compared to babies receiving placebo. The study targets a population of ELBW infants in whom the clinical decision to use or not use EA is currently most challenging -- infants that are clinically stable that did not have a known exposure to intraamniotic infection and were not born preterm for maternal indications. The primary outcome is the composite outcome of late-onset sepsis (LOS), necrotizing enterocolitis (NEC), or death during the index hospitalization. Secondary safety outcomes will include total antibiotic days, days to full enteral feedings, and common morbidities in preterm infants that have previously been linked to EA, e.g. retinopathy of prematurity and bronchopulmonary dysplasia. Weight and length z-score, and head circumference, are standard measures to be collected weekly by clinical team per a standardized protocol.

Skin Preparation for Foot and Ankle Surgery
Columbia, Missouri
Surgical site infections (SSIs) make about 31% of all nosocomial infections and they are the most common hospital-acquired infection. For foot and ankle elective interventions, SSI rate is reported between 0.4% and 3.6%. This study will investigate the effectiveness of skin cleaning with isopropyl alcohol and scrubbing with chlorhexidine soap before standard skin preparation in reducing microbial load and surgical site infections for elective foot and ankle surgeries. Current standard of care includes skin preparation with iodine or chlorhexidine solution prior to sterile draping and the start of surgery. Standard of care will be applied to all patients. The use of an additional "pre-scrub" with isopropyl alcohol and scrubbing with chlorhexidine soap will be applied to the experimental group. The control group will receive only the standard of care skin preparation with iodine or chlorhexidine solution prior to draping.

Dietary Intervention for Healthy Habits and Diet
Needham, Massachusetts
The PREDICT 3 study will build on previous research in over 2,000 individuals to further refine machine learning models that predict individual responses to foods, with the aim of advancing precision nutrition science and individualized dietary advice. The study incorporates both standardized and controlled dietary intervention, for the purpose of testing postprandial responses to specific mixed meals, in addition to a free-living period with a dietary record for measuring responses to a large variety of meals consumed in a realistic context, where the role of external factors (e.g. exercise, sleep, time of day) on postprandial responses may be determined. For the first time this PREDICT study is built on top of a commercial product which will allow access to a much larger group of participants who are already collecting large amounts of data through digital and biochemical devices that can contribute to science.

High-Soluble Fiber Diet for Sarcopenia
Boston, Massachusetts
Muscle health declines during aging. One factor that may impact muscle health is the community of bacteria that live in our intestines, but studies aimed at improving muscle health by targeting the gut in older adults are sparse. The primary goal of this study is to use a diet that is enriched in soluble fiber, which is exclusively utilized by gut bacteria to make substances that can impact muscle health, to improve muscle-related measures in older adults.

Standardized Oral Care for Premature Infant Health
Gainesville, Florida
Premature very low birth weight (VLBW) infants are susceptible to complications related to infrequent and non-standardized oral care. Although the benefits of frequent standardized oral care are known to reduce oral dybiosis (increased level of potentially pathogenic bacteria) and its associated complications in critically ill adults leading to established evidence-based guidelines, no such information exists for VLBW infants. The proposed study will prospectively follow 40 VLBW infants for 4 weeks following birth. Infants will be randomized into 1 of 2 groups. Standardized oral care will be performed every 3-4 hours (Group 1) and every 12 hours (Group 2). Aim 1 will evaluate the feasibility of frequent standardized oral care, Aim 2 will compare the oral microbiome between groups, and Aim 3 will compare respiratory outcomes including the incidence of ventilator associated pneumonia, bronchopulmonary dysplasia and need for respiratory support between infants receiving standardized oral care every 3-4 hours and every 12 hours. Issues related to recruitment, retention, randomization, acceptance by nursing staff, and treatment fidelity will be examined. Saliva samples will be obtained weekly and analyzed using 16S sequencing, respiratory cultures will be obtained weekly on ventilated infants, and respiratory outcomes will be collected from the medical records.

Haskap for Digestion
Bozeman, Montana
Diet is a key factor in managing health and individuals at risk of developing metabolic syndrome or other chronic diseases have the opportunity to use diet as a tool to improve their health. This can be complicated when considering the numerous variables that impact digestion and absorption of key health-promoting compounds in foods. One of these variables is the gut microbiome, a microbial community in the digestive tract that interacts with the foods we consume. The mechanisms the microbiome uses to interact with bioactive compounds in foods, like polyphenols, can modulate the health-promoting benefits of polyphenols. Polyphenols are secondary plant metabolites, commonly found in fruit, legumes, chocolate, coffee, and nuts among other foods that have been shown to improve cardiovascular and metabolic health, as well as reduce inflammation and oxidative stress.

Haskap Berries for Gut Health
Bozeman, Montana
Polyphenol-rich Haskap berries (Haskap) have untapped therapeutic potential to improve human health, and agricultural producers in northern U.S. states are poised to increase production if consumer demand increases. A critical knowledge gap is that little is known about the interactions between gut microbes and Haskap polyphenols to produce bioactive metabolites linked to downstream health impacts. Additionally, little is known about which Haskap varieties and harvest timing yield the greatest bioactive potential. This study aims to address these gaps by investigating the interaction of bioactive components in Haskap with gut microbiota and the resultant gut and serum metabolites, inflammation, and metabolic health, and then couple this with analysis of berries from different Haskap varieties and harvest times.

Donor Milk for Infant Microbiome
Calgary, Alberta
The objective of this novel study is to establish proof of concept using a pilot randomized controlled trial to determine the effect of DHM compared to formula supplementation on the microbiome in full-term infants who are born via caesarean section and require supplementation. Secondarily, this study aims to compare the infant health outcomes of sleep and growth between groups to assess if these outcomes are mediated by infant feeding type or potential differences in microbial signatures. Finally, this study will compare maternal outcomes of depression, anger, breastfeeding self-efficacy and breastfeeding rates between groups.
The infant gut microbiome plays a critical role in the developing immune, neurologic, and endocrine systems. Yet, most infants experience early life disruptions (ELDs) to their microbiome that have potential long-term health and development impacts. A major source of disruption is caesarean section (c-section) delivery because the infant is born surgically and is not exposed to important commensal bacteria required to establish the infant microbiome. Currently in Canada, over 28% of infants are born via c-section.
Exclusive breastfeeding can improve gut microbiota composition in infants who are born via c-section. However, approximately 60% of infants born via c-section require formula supplementation in their first week of life. Evidence indicates that even one bottle of formula can further disrupt the gut microbiome.
Donor human milk (DHM) is a superior alternative to formula when supplementation is required as its biotic properties minimize perturbations to the infant gut microbiome and may help to repair the microbiome in infants who experience ELDs. Yet, while DHM is well researched in preterm populations, evidence on the impact of DHM as a therapeutic intervention on the full-term infant gut microbiome is lacking.
The hypothesis of this study is: that replacing formula with DHM supplementation will minimize gut microbiome dysbiosis and foster homeostasis following supplementation. In addition, it is hypothesized that improved homeostasis will promote improved sleep and growth outcomes in participant infants. Finally, mothers whose infants receive DHM will have lower depression and anger scores and higher breastfeeding self-efficacy and exclusive breastfeeding rates compared to mothers whose infants receive formula.

Why Other Patients Applied
"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 Microbial Colonization 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 Microbial Colonization 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 Microbial Colonization 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 Microbial Colonization 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 Microbial Colonization 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 Microbial Colonization clinical trials ?
Most recently, we added MET-2 for Bacterial Blood Infections, Nasal Microbiota Transplant for Staphylococcus aureus Colonization and Haskap for Digestion to the Power online platform.Popular Searches
