Personalized fiber (B-fructan) diet for inflammatory bowel disease
This trial tests whether a tailored diet high in B-fructans can improve inflammatory bowel disease (ulcerative colitis or IBD-unclassified) in people in mild-to-moderate remission. It may help your gut and reduce bowel inflammation, and it involves colonoscopy and sample collection.
Edmonton, AlbertaAges 6–39 - NCT05617599Recruiting
Checks safety of a stent used in complex heart artery disease
This study looks at how safe and effective a specific stent (SUPRAFLEX CRUZ) is when used in real-world care for people with heart artery blockages in more than one artery. Some participants will also be selected if their heart pumping strength is reduced.
Elche, AlicanteAges 18 years+ - NCT05618626Recruiting
Lifestyle program to prevent fatty liver and heart disease
This trial tests whether a structured lifestyle program—focused on healthy living and resistance exercise—can help prevent fatty liver disease and heart-related problems. It may be helpful if you have early or mild fatty liver changes or risk factors, even if you also have gallstones.
Molina, Maule RegionAges 45–60 - NCT05623150Recruiting
Biopsy-based study for alcohol and metabolic liver disease
This trial studies people with liver disease linked to alcohol use or metabolic syndrome (a cluster of conditions like weight gain and insulin resistance). It uses recent standard-of-care liver biopsy results to better understand these chronic liver problems and how they relate to cancer risk.
NiceAges 18 years+ - NCT05626608Recruiting
Directional brain stimulation for Parkinson’s tremor and movement control
This trial tests a continuous electrical brain stimulation device placed in a deep brain area to help Parkinson’s symptoms—especially tremor and trouble with movement. It may help improve daily function and reduce periods when medicine does not work well.
Montpellier, FranceAges 18–70 - NCT05629559RecruitingPhase 1/Phase 2
Study drug 4D-310 for Fabry disease with heart problems
This Phase 1/2 study tests how safe and potentially effective 4D-310 is for adults with Fabry disease who have heart involvement. It may help people who can’t tolerate standard treatments like enzyme replacement therapy (ERT) or migalastat, or who still have disease progression.
MelbourneAges 18–65 - NCT05632432Recruiting
Heart tissue grafts to help the heart after surgery
This trial tests whether transplanting tiny heart “micrografts” from the left heart chamber area can improve heart function after cardiac surgery. It is meant for people with weakened heart pumping and heart failure symptoms despite medicine.
Helsinki, UusimaaAges 18–75 - NCT05633706Recruiting
Testing a capsule to study gut bacteria in the small intestine

Calgary, AlbertaAges 18–80 - NCT05635227Recruiting
Medications during heart surgery to help control breathing and circulation
This study looks at whether giving dexamethasone and olanzapine during certain heart surgeries can improve how blood flow and ventilation (breathing support) are managed. It’s meant to see if these medicines help the body handle heart-lung bypass more safely.
CopenhagenAges 18 years+ - NCT05638269Recruiting
Study of gut bacteria in people with serious long-term illness
This study looks at the types of gut bacteria in people living in certain parts of China who have serious long-term (chronic) illnesses. The goal is to better understand how gut bacteria differ and may help doctors in the future tailor care.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,802 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.
