Study of how you feel motion with sight and balance
This study looks at how people with normal health—and people with balance (vestibular) loss—perceive motion using their eyes and inner ear. You may help researchers understand how vision and balance systems work together.

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+ - NCT04146376Recruiting
Study of medicines for Von Willebrand disease during pregnancy
This study looks at how well a Von Willebrand disease treatment plan works during pregnancy, and whether some patients need extra “adjusting” of medicine. It may help prevent bleeding problems by matching treatment to each person’s lab results later in pregnancy.
Aurora, ColoradoAges 18 years+ - 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.
Boston, MassachusettsAges 18 years+ - NCT04157179Recruiting
MRI study of brain oxygen use in children and adults
This study uses an MRI scan to measure how your brain uses oxygen. It includes healthy participants and people with sickle cell disease or who previously needed ECMO, which may help researchers understand brain oxygen problems and how to monitor them.
St Louis, MissouriAges 3–50 - NCT04160507Recruiting
Biobank study collecting samples about kidney health in Black adults
This study builds a research “bank” (biorepository) of blood and other samples from Black adults with different stages of kidney health, including people with kidney disease and people without known kidney disease. It may help researchers better understand kidney risk and causes over time.
Durham, North CarolinaAges 18 years+ - NCT04162171Recruiting
SBRT treatment study for steady heart rhythm VT
This study looks at using SBRT (high-precision radiation) to treat a dangerous, steady heart rhythm called monomorphic VT. It is meant for people who keep having VT even after prior ablation attempts and after trying a class III “rhythm-stabilizing” medicine.
Halifax, Nova ScotiaAges Any age - NCT04162444Recruiting
Aortic valve reconstruction study for children
This trial studies a surgery approach to help fix a narrowed or leaking aortic valve in children. It aims to see how well the reconstructed valve works and how it affects the child’s heart function over time.
MoscowAges 4 weeks–12 years - NCT04163198Recruiting
Testing better airway clearance for weak breathing muscles
This study checks a device approach that helps move mucus out of the lungs in people with neuromuscular (nerve/muscle) conditions and weak breathing. It may help reduce mucus buildup and lower respiratory infections, but you must meet specific breathing and stability requirements.
London, LondonAges 18 years+ - NCT04164173Recruiting
Breathing therapies after heart surgery for lung overinflation
This study looks at breathing (respiratory) therapies to help after certain heart surgeries that can cause the lungs to feel overly inflated. If you’re eligible, you may receive and be assessed for how well these breathing treatments work during your recovery.
Dallas, TexasAges 18–80 - NCT04165109Recruiting
Down syndrome study to test memory and thinking changes
This study enrolls adults with Down syndrome to better understand how thinking and memory develop and change over time. It may help by building a “trial-ready” group and by measuring thinking in a careful, consistent way.
Phoenix, ArizonaAges 25–55 - NCT04166266Recruiting
Study of adults with hepatitis D and hepatitis B coinfection
This study follows adults who have ongoing hepatitis D infection along with hepatitis B. It aims to better understand this mixed infection and how these patients do over time.
AngersAges 18 years+ - NCT04180059RecruitingPhase 1
Anti-DP treatment after stem cell transplant to prevent relapse
This early-phase trial tests an anti-DP medicine given after an allogeneic (donor) stem cell transplant. It aims to improve outcomes by targeting immune cells linked to certain transplant match types and reducing relapse risk.
NantesAges 18–75 - NCT04179981Recruiting
CPAP treatment effects in older COPD and sleep apnea patients
This study looks at whether using positive airway pressure (often called CPAP) improves health outcomes in older adults who have both COPD and obstructive sleep apnea. It may help find ways to reduce symptoms and complications from “overlap” breathing problems.
Detroit, MichiganAges 60 years+ - NCT04179695Recruiting
Testing a new communication aid to improve patient-centered care
This study tests a new tool meant to help patients and healthcare teams communicate better and support “patient-centered care.” You may be invited to use the tool and complete study activities during your neurology care visits.
LilleAges 18–90 - NCT04182607Recruiting
Looking at outcomes after kidney donation surgery
This review looks at results for kidney donors and recipients who had kidney transplant surgery done either by hand-assisted or robotic methods. It aims to understand how these surgical approaches affect donor and recipient outcomes.
Dallas, TexasAges 18 years+ - NCT04181138Recruiting
Study of childhood primary sclerosing cholangitis types
This study follows children and young adults with primary sclerosing cholangitis (PSC) to understand the condition and how it shows up on scans or biopsy. It may help doctors better recognize PSC and choose the best next steps for care.
Los Angeles, CaliforniaAges 2–25 - NCT04183101RecruitingPhase 2
Aliskiren vs enalapril for C3 kidney inflammation
This trial tests whether aliskiren works better or as well as enalapril to treat C3 glomerulopathy/dense deposit disease confirmed by a kidney biopsy. It may help by improving kidney outcomes in people with this specific kidney condition.
GothenburgAges 6 years+ - NCT04185285Recruiting
Heart procedure registry for people who had stents
This trial is a registry that collects information from people who receive a heart artery procedure (percutaneous coronary intervention) at the study hospital. It mainly helps researchers understand outcomes and care patterns, and it only requires your consent to participate.
FribourgAges 17–120 - NCT04188808Recruiting
Study comparing patients with artery disease before surgery
This study looks at people with blocked leg arteries who are having planned (elective) open surgery for symptoms like leg pain when walking or at rest. It aims to better understand what to expect in these patients and how to compare outcomes between groups.
GothenburgAges Any age - NCT04200079Recruiting
Long-term follow-up study for people with COPD
This study follows people with COPD over time to better understand their lung health and how it changes. It may help researchers and doctors learn what factors affect breathing and long-term outcomes.
Kingston, OntarioAges 40–85 - NCT04201704Recruiting
Less IV fluids for children after trauma
This trial studies whether giving children less fluid through a vein after serious injury helps them recover safely. Children are enrolled soon after arrival to the ICU so the team can compare outcomes between different fluid amounts.
Buffalo, New YorkAges 6 months–15 years - NCT04203303Recruiting
Study how your gut microbes affect health and disease
This study looks at how the bacteria (microbes) living in and on your body relate to health and disease. It may help researchers understand what changes in these microbes mean for future treatments.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,808 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.
