Background: The chemical messenger dopamine carries signals between brain cells. It may affect addiction. Heavy use of pain medicines called opioids may decrease the amount of dopamine available to the brain. Researchers want to study if decreased dopamine decreases self-control and increases impulsiveness. Objective: To learn more about how opiate use disorder affects dopamine in the brain. Eligibility: Adults 18-80 years old who are moderate or severe opiate users Healthy volunteers the same age Design: Participants will first be screened under another protocol. They will: * Have a physical exam * Answer questions about their medical, psychiatric, and alcohol and drug use history * Take an MRI screening questionnaire * Give blood and urine samples * Have their breath tested for alcohol Participants will have up to 3 study visits. They will have 2-3 positron emission tomography (PET) scans. A radioactive chemical will be injected for the scans. Participants will lie on a bed that slides in and out of the donut-shaped scanner. A cap or plastic mask may be placed on the head. Vital signs will be taken before and after the PET scans. Participants will get capsules of placebo or the study drug. They will rate how they feel before, during and after. Participants will have their breath and urine tested each day. Participants will have magnetic resonance imaging (MRI) scans. They will lie on a table that slides into a cylinder in a strong magnetic field. They may do tasks on a computer screen while inside the scanner. Participants will have tests of memory, attention, and thinking. Participants will wear an activity monitor for one week....

The study team proposes a double-blind, comparative effectiveness, randomized controlled trial (RCT) to address the following goal: to determine the relative efficacy and adverse event profile of fosaprepitant compared to the standard of care antiemetic metoclopramide. Fosaprepitant and its active metabolite aprepitant are a relatively new class of antiemetic that exclusively acts in the central nervous system by blocking neurokinin (NK-1) which is a key signaling molecule in the centrally mediated aspects of the vomiting reflex. Currently, fosaprepitant and aprepitant both have only two United Stated Food and Drug Administration (USFDA) approved indications for nausea and vomiting: chemotherapy-induced and postoperative. Neurokinin inhibitors are highly effective and generally well-tolerated. Therefore, this class of medication may be a more appropriate medication for the millions of patients with nausea and vomiting that seek care in emergency departments (EDs). Intravenous fosaprepitant is converted to the active metabolite aprepitant on the order of minutes and is significantly cheaper to procure at this time.

Caffeine for Learning in Healthy Adults

Charlestown, Massachusetts
This research study aims to determine whether and how caffeine intake affects learning process through reward feedback compared to placebo. The data acquired from this study would improve our understanding on the consequence and mechanism of caffeine intake in the aspect of learning process. Participants will perform a reinforcement learning task (i.e. Probabilistic Selection Task) and a motor inhibition task (i.e. Go/NoGo task) in a brain scan. The scan will be done with the Siemens Biograph mMR positron emission tomography (PET)/ magnetic resonance imaging (MRI) 3 Tesla scanner. The PET allows us to see the changes in the "reward signals" - dopamine - in the brain using a radioactive dye called \[11C\]Raclopride. The MRI, on the other hand, enables us to take detailed pictures of the brain activities during cognitive tasks using a high-powered magnet. Reviewing these pictures will help us understand the influence of caffeine on reward signals and brain activities during the learning process.

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've tried several different SSRIs over the past 23 years with no luck. Some of these new treatments seem interesting... haven't tried anything like them before. I really hope that one could work."

ZS
Depression PatientAge: 51

"I've been struggling with ADHD and anxiety since I was 9 years old. I'm currently 30. I really don't like how numb the medications make me feel. And especially now, that I've lost my grandma and my aunt 8 days apart, my anxiety has been even worse. So I'm trying to find something new."

FF
ADHD PatientAge: 31

"My orthopedist recommended a half replacement of my right knee. I have had both hips replaced. Currently have arthritis in knee, shoulder, and thumb. I want to avoid surgery, and I'm open-minded about trying a trial before using surgery as a last resort."

HZ
Arthritis PatientAge: 78

"I changed my diet in 2020 and I’ve lost 95 pounds from my highest weight (283). I am 5’3”, female, and now 188. I still have a 33 BMI. I've been doing research on alternative approaches to continue my progress, which brought me here to consider clinical trials."

Frequently Asked Questions

How much do Dopamine Receptor 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 Dopamine Receptor 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 Dopamine Receptor 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 Dopamine Receptor 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 Dopamine Receptor 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 Dopamine Receptor clinical trials?

Most recently, we added VK4-116 for Opioid Use Disorder, Fosaprepitant vs Metoclopramide for Nausea and Vomiting and Solriamfetol for Binge Eating Disorder to the Power online platform.
