Recruiting studies
- NCT02821806Recruiting
Donate blood cells to help grow immune cells for therapy
This is a study that recruits healthy adults to donate a type of blood cell (PBMCs) so researchers can grow T cells for future adoptive cell therapy. It tests a process for collecting and expanding immune cells; participation mainly involves blood donation and health screening.

Collecting bladder/urothelial cancer tissue for future research
This study looks at urothelial cancer (often bladder cancer) samples taken during diagnosis or standard treatment. It may help researchers better understand the disease by using tissue that doctors already need to collect for care.
Bethesda, MarylandAges 18–120 - NCT02484885Recruiting
Breath-hold MRI study to test imaging reliability
This study uses a special MRI gas (xenon-129) and scanner software to check how reliably images can be repeated. You may be able to help researchers improve MRI technology, as long as you can safely do the breathing and MRI scanning steps.
London, OntarioAges 18–85 - NCT02851043Recruiting

Study of growth, weight, and behavior in children
This study looks at how children’s growth and weight relate to thinking, mood, and behavior. It may help researchers understand what patterns affect health and development so they can guide better support for families.
Bethesda, MarylandAges 8–100 - NCT02639299Recruiting
Screening healthy adults for malaria vaccines and drug studies
This study screens healthy adults to see who can join future malaria vaccine or investigational malaria drug studies, including a controlled malaria exposure. It may help researchers test safer vaccines/drugs, but participation requires good health and strict medical eligibility.
Bethesda, MarylandAges 18–50 - NCT02327884Recruiting
Study saliva and related diseases to learn health patterns
This study looks at diseases that involve the salivary (saliva) glands, and may also include people with active hepatitis, oral cancer, or healthy adults.

Study of taste changes before and after bariatric surgery
This study looks at how your sense of taste works before and after bariatric weight-loss surgery. It may help doctors understand why eating patterns change after surgery.
BaselAges 18–55 - NCT02446262Recruiting
Study of how the brain and mind shape pain in healthy adults
This study tests how people sense heat and pain, and how the brain and emotions may influence that experience. It is designed for healthy adults and may involve training sessions and (for some parts) MRI scanning.
Bethesda, MarylandAges 18–50 - NCT02543983RecruitingPhase 2
Brain scan and ketamine study for suicidal thoughts
This trial studies how ketamine affects the brain in people dealing with suicidal thoughts or an active suicide crisis. It uses questionnaires, consent testing, and brain imaging to look for biological changes that may relate to symptom improvement.
Bethesda, MarylandAges 18–70 - NCT03065335RecruitingPhase 1
Ketamine plus brain imaging to study response in depression
This early-stage study tests how ketamine given once and then repeatedly may change brain signals and related biomarkers in people with major depression. If you’re eligible, the team will use brain imaging and assessments to see who responds and why.
Bethesda, MarylandAges 18–65 - NCT07656454RecruitingPhase 1
Comparing two ways to give CDR132L in healthy volunteers
This study measures how well the drug CDR132L enters the blood when injected under the skin, compared to injection into a vein. It is done in healthy volunteers to find the best way to give the drug.
BerlinAges 18–55 - NCT07515638Recruiting
Immune System Study for Autoimmune Diseases
This research study collects samples and information from people with rheumatoid arthritis, lupus, or scleroderma, plus healthy volunteers, to better understand how the immune system works in these conditions. By comparing these groups, researchers hope to find new ways to treat and manage autoimmune diseases.
MontpellierAges 18 years+ - NCT07604116RecruitingPhase 1
Safety study of SST001 in Parkinson's and MSA patients
This is an early-stage study testing a new experimental medicine called SST001 in people with Parkinson's disease (PD) and multiple system atrophy (MSA), as well as healthy volunteers. The study checks whether SST001 is safe, how the body processes it, and where it goes in the body using imaging scans.
Wuxi, JiangsuAges 40 years+ - NCT07413666RecruitingPhase 1
Safety study of ORX489 in healthy adults
This phase 1 trial is testing an experimental drug called ORX489 in healthy adults aged 18 to 60. The goal is to see if it is safe and how the body processes it, which helps decide if it can be tried in people with certain conditions.
Lincoln, NebraskaAges 18–60 - NCT07421011RecruitingPhase 1
Comparing two forms of a drug for healthy volunteers
This study tests two different versions of a drug called Trimedat to see if they work the same way in the body. It is for healthy volunteers to understand how the drug is absorbed and if it is safe.
Saint PetersburgAges 18–45 - NCT07422207RecruitingPhase 1
Safety study of ME3241 in healthy adults
This trial is testing a new intravenous medicine (ME3241) for safety and how the body handles it. It's for healthy adults, so researchers can see how the drug works before testing it in people with the target condition.

Common questions
- Are there clinical trials for volunteers?
- Yes. Clin2 currently lists 528 recruiting volunteers studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a volunteers trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a volunteers trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
