Recruiting studies
- NCT04150042RecruitingPhase 1
Test of chemotherapy plus your own stem cells for metastatic cancer
This Phase 1 trial tests a treatment approach using standard chemotherapy along with stem cells taken from you to treat metastatic pancreatic or breast cancer. It is mainly designed to check safety and find the best way to give the treatment, and it may offer an option for people whose cancer has spread.

Exercise bands versus muscle stimulation for people with cancer
This trial compares two types of exercise—flexible resistance band training versus a type of muscle stimulation—to see which is safe and helpful during cancer treatment. It may help improve physical function while you’re receiving anti-cancer care.
ErlangenAges 18 years+ - NCT04124029Recruiting
How head injuries affect brain health
This study looks at how mild or moderate head injuries (concussions) may relate to brain conditions like chronic traumatic encephalopathy (CTE) and Alzheimer's disease. By comparing people with and without head injuries, researchers hope to learn more about what causes brain changes over time.
Boston, MassachusettsAges 30–90 - NCT04074135RecruitingPhase 2
Study of pancreatic tumors in people with VHL
This trial studies the natural course and management of pancreatic neuroendocrine tumors in people with von Hippel–Lindau (VHL) disease. It may help doctors better predict how these pancreatic findings change over time and how to manage them.
Bethesda, MarylandAges 12 years+ - NCT04097561RecruitingPhase 1
Belimumab safety study for low CD4 counts and autoantibodies
This Phase 1 study tests how safe belimumab is for people with idiopathic CD4 lymphopenia (low protective white blood cells) and signs of autoantibodies. It aims to learn whether the treatment is tolerable and could be a future option for people with this immune condition.
Bethesda, MarylandAges 18–70 - NCT04052022Recruiting
Study of TB flare-ups in people without HIV
This study looks at why some people with tuberculosis (TB) get worse or develop new inflammation after they initially start improving on treatment—called a “paradoxical reaction.” It collects blood and tissue samples to better understand these flare-ups and guide future care.
Bethesda, MarylandAges 18–99 - NCT04047628RecruitingPhase 3
MS patients with active relapsing disease comparing two treatment plans
This Phase 3 study compares the best standard MS treatment (chosen by your doctors) versus an approach called autologous hematopoietic stem cell transplant (AHSCT) for people with highly active, treatment-resistant relapsing multiple sclerosis. It aims to see which option controls MS disease activity better and keeps you safer over time.
Palo Alto, CaliforniaAges 18–55 - NCT04065516Enrolling by invitation
Test for reflux treatment after POEM for achalasia
This study looks at a specific treatment (“ARAT”) to help people who develop acid reflux after a procedure called POEM for achalasia. It may help reduce reflux symptoms and abnormal acid levels in the stomach/esophagus after the original procedure.
Mexico City, Mexico CityAges 18 years+ - NCT04145258RecruitingPhase 3
Stronger TB treatment for meningitis to reduce deaths
This trial tests if giving a stronger combination of TB drugs for meningitis can save more lives. It's for patients who have been diagnosed with tuberculosis meningitis and have not yet started more than 5 days of TB treatment.
AbidjanAges 15 years+ - NCT04097145Recruiting
Heart valve repair for severe leaking tricuspid valve
This trial tests a catheter-based procedure (done through the blood vessels) to repair a severely leaky tricuspid valve. It may help people with symptoms or past hospitalizations from tricuspid valve leakage who are higher-risk for standard surgery.
Phoenix, ArizonaAges 18 years+ - NCT04094311RecruitingPhase 3
Testing a modified cell therapy when product quality is off-spec
This study looks at using tisagenlecleucel, a cell therapy, when the final product does not meet routine “commercial release” quality standards. It focuses on whether it can still be given safely and effectively to people with serious or life-threatening illness.
Hamilton, OntarioAges birth–100 years - NCT04028687Recruiting
Study of a hip stem used in select adult hip replacements
This trial follows people who have had a hip replacement using a specific “Taperloc Complete” stem. It is meant to monitor outcomes after surgery and see how well the stem performs over time for certain non-infectious hip problems.
Henderson, NevadaAges 18 years+ - NCT04073420Recruiting
Cardiac surgery registry to track Medtronic device outcomes
This registry collects real-world information from people who have had—or plan to have—an eligible Medtronic cardiac surgery device. It aims to better understand how these treatments do over time and help guide future care.
Marietta, GeorgiaAges Any age - NCT04064008Enrolling by invitation
Long-term follow-up for a specific hip revision stem
This study follows people who had a hip replacement redone (revision) because of bone healing problems or hardware removal, using a specific revision femoral stem. It checks how the stem does over time and follows up for up to 10 years after surgery.
OtwockAges Any age - NCT04100486Enrolling by invitation
Testing a noninvasive device to measure your body signals
This study uses a noninvasive bioelectronic device to record your body’s automatic (involuntary) signals. The goal is to see how well the device can analyze these signals and how your body responds in a controlled setting.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,548 recruiting general population (no specific condition or disease) 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 general population (no specific condition or disease) 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 general population (no specific condition or disease) 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.
