This trial compares a drug-coated balloon (medicated balloon) to a drug-eluting stent (medicated mesh tube) for treating new blockages in heart arteries. It is designed for patients with a high risk of bleeding who have completed a short course of anti-clotting medication and have been event-free for at least one year.
AnsanAges 19 years+ - NCT06535568Recruiting
Comparing one vs two blood thinners after heart artery balloon treatment

Milan, MIAges Any age - NCT04029363Recruiting
Transcatheter mitral valve procedure for high-surgery-risk patients
This trial studies a newer, catheter-based mitral valve treatment in people with moderate-severe to severe mitral valve leaking who are at high risk for open-heart surgery. It may help improve symptoms and heart function without traditional surgery, but you must meet key heart, anatomy, and safety requirements.
Darlinghurst, New South WalesAges 18 years+ - NCT06276374Recruiting
Dual antiplatelet therapy after carotid artery stenting for high bleeding risk
This trial tests if taking two blood thinners (dual antiplatelet therapy) after a carotid artery stenting procedure is safe and effective for patients who have a higher risk of bleeding. It focuses on people with significant blockages in the neck arteries who are also at increased risk for serious bleeding or brain bleeds.
SeoulAges 19 years+ - NCT05152888RecruitingPhase 4
Testing a cholesterol drug to improve heart blood flow on scans
This trial studies whether lowering LDL (“bad cholesterol”) with a PCSK-9 inhibitor (evolocumab) improves blood flow to the heart, measured by special PET scans. It’s for people over a certain age who have stable coronary artery disease and a higher risk of heart problems.
Boston, MassachusettsAges 50–90 - NCT06053086Recruiting
Adaptive radiation therapy for breast cancer patients at high risk
This trial tests a new way to deliver radiation therapy that adapts to each patient's body changes during treatment. It is for women who had breast cancer surgery and need radiation to the whole breast and nearby lymph nodes, and who have been identified as being at risk for breast fibrosis.
MontpellierAges 18 years+ - NCT05893030Recruiting
Monitoring pain and sleep medicines to prevent complications after surgery
This study looks at whether closely monitoring opioid and sleep medicines during and after surgery can lower organ problems and death in older adults at high risk. If you qualify, your team will track how these medicines are given to help keep you safer in the postoperative period.
AmiensAges 75 years+ - NCT05369442Recruiting
Blood-thinner plan study for people with high bleeding risk after PCI
This trial studies which blood-thinner (antiplatelet) strategy is safest and most effective for people at high risk of bleeding after a procedure called PCI. It also looks at longer-term outcomes and whether adjusting treatment can improve safety without losing heart protection.
Sichuan, SichuanAges Any age - NCT03805919Recruiting
Study for men with high inherited risk of prostate cancer
This study is for men who have a known inherited gene change that raises their prostate cancer risk. It aims to help prevent or detect prostate cancer earlier, and you may be asked to undergo MRI and other study steps.

MRI study of triple inhaler for COPD with breathlessness
This study uses a special MRI scan to see how well a single triple inhaler works for people with COPD who have moderate to severe shortness of breath or feel their health is not good. It compares two groups: those with a low risk of flare-ups and those with a high risk, to find out if the treatment helps both groups.

Testing immune response after prostate radiation with or without a drug
This study checks how your immune system’s cancer-fighting cells change after stereotactic body radiation (SBRT) to the prostate. It compares SBRT alone versus SBRT plus an immunotherapy drug (PDS01ADC) in men with intermediate- or high-risk localized prostate cancer treated with hormone therapy (ADT).

Common questions
- Are there clinical trials for high risk?
- Yes. Clin2 currently lists 922 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.
