Antibiotics Impact on Healthy Subjects
Bethesda, Maryland
More than 250 million courses of antibiotics are prescribed annually in the ambulatory care setting in the United States alone, including more than 40 million in children under 18 years of age. The perception that antibiotic use has minimal attendant adverse side effects contributes to the over-utilization of antibiotics in clinical circumstances when they are not strictly indicated. We have learned much about the human microbiome. The emerging view is of profound life-long bi-directional interactions between our microbiota and our cells. Perturbations in the microbiota affect metabolic, immune, and cognitive physiology in experimental animal models. When a person takes an antibiotic, the antibiotic diffuses via the blood into all body compartments, selecting for resistance. We propose to examine the effects of two commonly used antibiotics (the beta-lactam, amoxicillin and the macrolide azithromycin) on human microbial populations and on metabolic and immune physiology, studying healthy human volunteers in a randomized controlled clinical trial at the NIH Clinical Center. Our hypothesis is that in addition to acutely perturbing the human microbiome, these agents will have measurable metabolic and immunologic effects, with residual effects in the weeks that follow. To test this hypothesis, we will assess the effects of a brief therapeutic course of antibiotics on microbiome and metagenome composition. After an initial evaluation period, antibiotics will be given for 7 days or 5 days (depending on the antibiotic), and there will be a post-treatment evaluation. A control group will receive no drug intervention. Specimens will be obtained from multiple sites at each of 10 time points occurring before, during, and after antibiotic administration, and used for estimating bacterial and fungal composition and gene content. We will also assess the effects of the antibiotic course on markers of innate and adaptive immunity as well as markers of metabolic and hormonal physiology. A subgroup of subjects will be studied in the clinical center metabolic chamber to assess 24-hour energy expenditure and its components (sleeping, diet-induced, and activity energy expenditure), as well as macronutrient oxidation rates (carbohydrate, fat, and protein), during 3 of the 10 study visits. In addition to the primary data analyses, we will build a model that integrates the temporal data to begin to understand the complex intertwined physiology between microbiome and host.

Sociocultural Influences on Pain Assessment
Bethesda, Maryland
Objective
The current proposal investigates behavioral, psychophysiological, and social processes that may help explain biases and disparate outcomes in pain. Health disparities, or health outcomes that adversely affect disadvantaged populations, are pervasive and apparent in many diseases and symptoms, including pain. Pain is the number one reason individuals seek medical treatment. Health disparities in pain encompass both differences in pain experience and treatment for pain. For instance, research indicates that Black individuals report increased pain and have reduced pain tolerance relative to White individuals, yet doctors are less likely to treat minority patients pain and underestimate their pain experience. This project aims to address this systemic discrepancy by focusing on interpersonal processes that may contribute to these disparities, including socially-relevant responses to pain (i.e. pain expression) and pain assessment (e.g. visual attention). The proposed research aims to determine whether the study of pain expressions and their assessment can yield insights on how social factors shape pain and its treatment. Further, we test the efficacy of potential interventions designed to improve accuracy and reduce biases in pain assessment. If successful, this work will form the foundation of a new research program that will link the field of pain research with the field of social neuroscience, and forge new insights on the critical problem of health disparities in pain.
Study population
We will accrue up to 700 total healthy volunteers to target 240 completers
Design
Our overall aim is to understand how social factors influence the assessment and management of pain, and to gain insight into psychosocial processes that may underlie health disparities in pain. We propose a series of studies designed to test these links. First, we will measure pain perception and physiological responses to painful stimuli in a diverse group of individuals to test for sociocultural and biological influences on pain and pain-related responses. In subsequent studies, new participants ("perceivers") will view images of these initial participants ("targets") and will provide estimates of 'targets' pain experience. We will measure a) whether perceivers can accurately estimate 'targets' pain experience; b) whether accuracy differs as a function of similarity between target and perceiver (ingroup vs outgroup); and c) whether individuals can improve accuracy through feedback.
Outcome measures
Primary outcome measures for all experiments will be decisions about pain (experienced by self or other) measured with visual analogue scales, reaction time, and/or categorical judgments (pain/no pain). We will also measure physiological responses (e.g., facial muscle response, skin conductance, pupil dilation) and brain responses using functional magnetic resonance imaging (fMRI) as secondary outcome measures. We will test whether pain and pain-related responses varies as a function of sociocultural/demographic factors (e.g. race, ethnicity, sex) and whether accuracy in assessing others' pain is influenced by group similarity (i.e. ingroup vs. outgroup) and training (e.g. performance-related feedback)....

Room Temperature Effects on Calorie Burn in Obesity
Bethesda, Maryland
Background:
- The way that the body burns calories is known as energy expenditure. Some studies show that when we are cold, we burn more calories to keep our bodies warm. Brown fat is a special kind of fat that can use energy to keep the body warm. Small animals and infants have been known to have brown fat for many years. Recently, it has been suggested that adult humans also have brown fat. If brown fat becomes active (burns calories) in adult humans when exposed to cold, then these people would tend to burn off more calories and might not gain weight easily. Learning more about the relationship between energy expenditure, brown fat, environmental temperature, and body temperature may help explain why some people become obese and other people do not.
Objectives:
* To better understand how the body burns calories when exposed to different temperatures.
* To study brown fat and how it burns calories in cold temperatures.
Eligibility:
* Healthy men between 18 and 35 or 55 and 75 years of age.
* Healthy women between 18 and 35 years of age.
* To control for ethnicity, participants must be non-Hispanic whites or African Americans.
Design:
* Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected.
* Participants will stay in the Metabolic Unit of the National Institutes of Health Clinical Center as inpatients for no more than 14 days. The length of the hospital stay will depend on how participants respond to the different study temperatures.
* Every afternoon, participants will walk for 30 minutes on a treadmill. All meals will be provided.
* Participants will stay up to 5 hours per day in a specialized room with different temperature settings. Temperatures will range from about 61 degrees to 88 degrees Fahrenheit. Body temperature, activity, calorie burning, and cold/hot sensations will be monitored. On the study day of the coldest temperature, participants will have an imaging study to look for brown fat activity.
* Participants will be compensated for their time and participation at the end of the study.

Psychological Interventions for Pain Perception
Bethesda, Maryland
Background:
- Painful stimuli cause changes in a network of brain regions called the "Pain Matrix." But most of these regions respond to many other stimuli, not just pain. Researchers want to understand how different factors influence pain. They want to test what happens when people expect different levels of pain and receive treatments that can modify pain. They want to see if these factors influence decisions about pain and how the body responds to it. They also want to compare pain with responses like taste and vision.
Objectives:
- To better understand how pain and emotions are processed and influenced by psychological factors.
Eligibility:
- Healthy volunteers ages 18-50.
Design:
* This study requires 1 to 2 clinic visits that last 1 to 3 hours.
* Participants will be screened with medical history and physical exam.
* Some participants will have one or more magnetic resonance imaging (MRI) scans of their brain. For MRI, participants will lie on a table that slides in and out of a cylinder. The scanner makes loud knocking noises. They will get earplugs.
* Participants heart activity will be recorded with electrocardiogram. Their pulse, sweating, and breathing will be monitored.
* Some participants will take a taste test. Others may perform simple tasks. Others may receive pain in their arm, leg, or hand. The pain will come from heat or electric shocks. Others may judge pain using a topical pain-relieving cream. Some of these tests may be given during MRI.
* Participants will fill out questionnaires.
* The study will last 3 years.

TMS for Cognitive Impairment
Toronto, Ontario
The goal of this interventional study is to develop an individualized approach using transcranial magnetic stimulation (TMS) in a high-precision manner. This approach will use TMS to modulate brain activity at multiple locations simultaneously. Functional magnetic resonance imaging (fMRI) and electroencephalograph (EEG) will record the responses and guide the stimulation. Specifically, the placement and orientation of TMS coils will be tailored to stimulate the targeted functional brain areas informed by fMRI. To maximize the interventional effect, stimulation pulses will be delivered based on EEG oscillations.

Advanced MRI Techniques for Cardiovascular Disease
Bethesda, Maryland
Background:
Magnetic resonance imaging (MRI) is an important non-invasive tool to study and diagnose cardiovascular disease. MRI scanners use strong magnetic fields and radio waves to create pictures of body organs. Researchers want to find better MRI methods and new ways of imaging cardiovascular disease and better understand normal and abnormal cardiovascular and brain function. Researchers are also interested in seeing if gadolinium, the commonly used MRI contrast agent, stays in the body long after the MRI was performed.
Objectives:
To develop new methods for imaging the heart and other organs of the body.
To describe cardiovascular diseases using newer MRI methods
To look at the relationship between cardiovascular disease and cardiovascular risk factors and other organ systems
To look for gadolinium deposits in the brain from prior exams.
Eligibility:
Healthy people and people with known or suspected cardiovascular disease ages 7 and older may be eligible for this study.
Researchers may be particularly interested in those who:
* Have suspected or known cardiovascular disease
* Were previously exposed to a gadolinium-based contrast agent,
* Need to have a heart MRI scheduled
* Need a test of the heart or other body part or will be undergoing a future cardiac catheterization
Design:
There are multiple arms to the study with optional components; therefore, there are multiple variations as to what an individual participant s experience may involve.
Participants will have an MRI scan lasting up to 2 hours. The scanner is a large hollow tube. During the scan, there may be loud knocking and buzzing sounds caused by the scanner. Participants will lie on a table that slides in and out of the tube. Their vital signs may be monitored.
Participants may have a test of heart electrical activity using wires connected to pads on the skin.
Participants may have blood drawn.
Participants may be injected with an MRI contrast agent through a plastic tube inserted in the arm.

Transcranial Magnetic Stimulation for Healthy Volunteers
Baltimore, Maryland
Background:
People with substance use disorder (SUD) often have changes in brain function that can make it difficult to control drug-seeking behavior. These changes may heighten the urge to use drugs or lessen the desire to seek nondrug-related rewards. Researchers want to know how a technique called transcranial magnetic stimulation (TMS) may cause changes in brain activity that may help people with SUD.
Objective:
To test TMS in healthy volunteers.
Eligibility:
Healthy people aged 18 to 45 years who are right-handed.
Design:
Participants can volunteer for up to 5 different experiments. Each experiment requires 2 to 8 clinic visits. Each visit will last 3 to 7 hours.
Some visits will include TMS. A coil will be placed on the participant s head. A brief electrical current will pass through the coil to create a magnetic field. Participants may feel a tapping or pulling sensation on the skin under the coil. They may feel a twitch in their face, neck, arm, or leg muscles. Participants may be asked to tense certain muscles during TMS.
Some visits will include functional magnetic resonance imaging (fMRI) scans. Participants will lie on a bed that slides into a large tube. They will perform tasks on a computer inside the tube. The fMRI will show which parts of the brain are used during each task.
Participants will perform tasks on a computer. Some tasks may be done at a desk as well as during TMS and fMRI. Participants may look at images, listen to sounds, smell odors, or taste flavored liquids. Their vital signs may be monitored and their eye movements may be tracked during tasks.

Nicotine Patch for Depression
Baltimore, Maryland
Background:
Nicotine dependence leads to about 480,000 deaths every year in the United States. People with major depressive disorder (MDD) are twice as likely to use nicotine compared to the general population. They have greater withdrawal symptoms and are more likely to relapse after quitting compared with smokers without MDD. More research is needed on how nicotine affects brain function in those with MDD.
Objective:
To understand how nicotine affects symptoms of depression and related brain function.
Eligibility:
People aged 18 to 60 years, at the time of consent, with and without MDD who do not smoke cigarettes or use other nicotine products.
Design:
Participants will have 2 or 3 study visits over 1 year.
Participants will have 2 MRI scans no less than 4 days apart. Each scan visit will last 5 to 7 hours. At each scan, they will have urine and breath tests to screen for recent use of alcohol, nicotine, and illegal drugs.
Before each scan, they will take 1 of 2 medications: nicotine or placebo. Participants will receive each medication once. They will not know which medication they are receiving at each scan.
For each MRI scan, they will lie on a table that slides into a cylinder. Sometimes they will be asked to lie still. Sometimes they will complete tasks on a computer. Tasks may include identifying colors or playing games to win money. Each scan will take about 2 hours.
Participants will answer questions about their thoughts, feelings, and behaviors before and after each scan.
They will have a blood test after each scan.

Light Exposure for Sleep and Circadian Rhythms
Boston, Massachusetts
The goal of this clinical trial is to learn how the pupil responds to different light stimuli and how that relates to sleep and daily rhythms in healthy people of different ages.
The main questions it aims to answer are:
* Does the eye's pupil response to light stimuli differ by the sex and age of the participant?
* Is the eye's pupil response to light stimuli related to each participant's sleep timing, their body clock timing, and their hormone responses to light.
Participants will have a special eye exam and complete questionnaires before starting the study to see if they can participate. If they can participate, they will wear a special watch that monitors their activity and light levels for one week. Then they will live in a research room at the Mass General Hospital for 3 days/2 nights during which we will test their pupil response to light, their body clock timing, and their hormone responses to light.

Frequently Asked Questions
How much do Normal Physiology 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 Normal Physiology 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 Normal Physiology 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 Normal Physiology 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 Normal Physiology 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 Normal Physiology clinical trials?
Most recently, we added Transcranial Magnetic Stimulation for Healthy Volunteers, Light Exposure for Sleep and Circadian Rhythms and TMS for Cognitive Impairment to the Power online platform.
