Study of heart risk in people starting dialysis
This study looks at heart (cardiovascular) risk factors in people who are just starting dialysis for chronic kidney failure. It may help doctors better understand what heart-related issues to watch for early during dialysis.
Castelnau-le-LezAges 18–90 - NCT04666961RecruitingPhase 2
Hormone therapy before surgery for extensive DCIS
This Phase 2 study tests whether taking hormone medicine before surgery can change the surgical plan and outcomes for people with extensive ductal carcinoma in situ (DCIS). It is for estrogen-receptor positive DCIS and aims to see how this “neoadjuvant” approach affects treatment decisions.
AngersAges 40 years+ - NCT05339178Recruiting
Study of quality of life in gum disease patients on maintenance care
This study asks people with periodontitis (gum disease) who are in ongoing maintenance visits after their active treatment. It looks at how supportive periodontal therapy affects quality of life.
ViennaAges 18–130 - NCT05353946Recruiting
Rotational atherectomy elective vs emergency for heavily calcified blockages
This trial compares doing a special procedure (rotational atherectomy) before an emergency is needed versus using it as a rescue during a heart artery procedure. It is designed for people with very hard, calcified artery blockages and long-term kidney impairment, to see which approach works better and is safer.
MadridAges 18–100 - NCT05145517Recruiting
Follow-up study for people who received a JOTEC vascular graft
This study tracks people 18 and older who were treated with a JOTEC vascular graft. It checks how well the graft and follow-up care work over time for certain blood vessel problems.
Münster, North Rhine-WestphaliaAges 18 years+ - NCT04578301Recruiting
Predicting who develops serious liver worsening after surgery
This study looks at your liver health before and after surgery to predict the risk of “acute-on-chronic liver failure,” which means a sudden worsening of liver function on top of an existing liver condition. If you qualify, your doctors may use study data to better identify who needs closer monitoring after surgery.
BonnAges 18 years+ - NCT03455478Recruiting
Study of adult vision health in Shanghai residents
This study looks at the eye health of adults who live in Shanghai. It may help researchers understand vision problems in the local population and improve future eye care.
Shanghai, Shanghai MunicipalityAges 18–100 - NCT04011527Recruiting
Registry for heart stent procedure using rotational atherectomy
This study collects information from people who are having a heart procedure called rotational atherectomy to open blocked heart arteries. It helps doctors better understand how the procedure is used and its outcomes.

Study of biliary atresia in children with heart disease
This trial is studying children who have biliary atresia, a serious liver problem, including some who also have tetralogy of Fallot (a congenital heart condition). It also includes healthy children for comparison, and may help researchers understand the illness and treatments better.

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.
