Chicory root fiber for melanoma patients after surgery
This study tests whether adding a high-fiber chicory root supplement to your diet can help people after melanoma surgery. Researchers want to see if it improves your immune system and gut health to prevent the cancer from coming back.
Groningen, Provincie GroningenAges 18 years+ - NCT06513247Recruiting
Screening for type 1 diabetes in high-risk relatives
This study screens high-risk children for early signs of type 1 diabetes by testing relatives who already have the condition. It aims to catch diabetes early so treatment can start sooner.
RiyadhAges 2–18 - NCT05918263Recruiting
Exercise to slow prostate cancer in men on active surveillance
This trial tests whether moderate exercise can help keep low-risk prostate cancer from growing in men who are monitoring their cancer instead of treating it right away. It may be especially helpful for men with certain risk factors like obesity or being Black or African American.
Boston, MassachusettsAges 18 years+ - NCT06624696RecruitingPhase 4
Inhaled penehyclidine to prevent breathing problems in children having eye surgery
This study tests whether giving a medication called penehyclidine (given as a mist inhaled before surgery) can help prevent breathing problems in children aged 3–7 who are having eye surgery and are at risk for such problems. The medicine is compared to a placebo (a mist with no active drug).
Guangzhou, GuangdongAges 3–7 - NCT06671015Recruiting
Comparing breathing support methods after a breathing tube is removed in people with heart failure
This study compares two types of breathing support—a high-flow nasal cannula and noninvasive ventilation—to see which one better prevents the need for re-inserting a breathing tube in people with systolic heart failure who are at high risk for breathing problems after the tube is removed.
New Haven, ConnecticutAges 18 years+ - NCT07042438RecruitingPhase 2
Fecal transplant to improve CAR T therapy for lymphoma
This study tests whether a fecal transplant (transferring healthy gut bacteria) can improve outcomes for people with certain lymphomas who have taken strong antibiotics and are about to get CAR T-cell therapy (Yescarta). The goal is to see if rebuilding gut bacteria helps the treatment work better.
Duarte, CaliforniaAges 18 years+ - NCT04743479Recruiting
AI screening for pancreatic cancer in higher-risk people
This trial uses an artificial-intelligence tool to help detect pancreatic cancer earlier and track people at higher risk. You may be asked to complete questionnaires and have imaging tests like MRI or CT to see how well the approach works.
ShanghaiAges 50–75 - NCT06632613RecruitingPhase 2
Trial of ENN0403 to prevent kidney injury after heart surgery
This study tests a new drug (ENN0403) given during heart surgery to see if it prevents acute kidney injury—a sudden drop in kidney function. The trial is for people who are already at higher risk due to their specific heart surgery and other health factors.

Common questions
- Are there clinical trials for high risk?
- Yes. Clin2 currently lists 923 recruiting high risk 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 high risk 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 high risk 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.
