Itraconazole with ablation to prevent esophageal cancer in Barrett's esophagus
This trial tests if adding the antifungal drug itraconazole to standard ablation therapy can help prevent esophageal cancer in people with high-risk Barrett's esophagus. You must have a confirmed diagnosis of Barrett's esophagus with low- or high-grade dysplasia or early-stage cancer, and be planning to have ablation treatment.
Kansas City, KansasAges 18 years+ - NCT06735690RecruitingEarly Phase 1
Immune cells plus vaccine after stem cell transplant for leukemia
This trial is for people with high-risk acute lymphoblastic leukemia who are getting a stem cell transplant from a family donor. After transplant, you'd receive a treatment that combines specially designed immune cells (CAR T cells) that target your leukemia, plus a vaccine that helps those cells work better.
Duarte, CaliforniaAges 18 years+ - NCT05841550RecruitingPhase 1/Phase 2
Vaccine study for high-risk smoldering or myeloma
This Phase 1/2 trial tests a cancer vaccine (TG01/QS-21) in people with high-risk smoldering multiple myeloma or multiple myeloma. It aims to see how safe the vaccine is and whether it can help the immune system control the disease.
Oslo, OsloAges 18 years+ - NCT05123625Recruiting
Testing lymph node removal during bladder cancer surgery
This study looks at whether removing nearby lymph nodes during radical cystectomy (bladder removal) improves outcomes for people with high-risk non–muscle-invasive bladder cancer. It may help doctors choose the best surgical approach to reduce the chance of cancer coming back.
Nanjing, JiangsuAges 18–75 - NCT06717958RecruitingPhase 2
Ivosidenib after stem cell transplant for IDH1-mutated AML or MDS
This trial tests whether taking ivosidenib after a stem cell transplant can help prevent leukemia from coming back in people with a specific gene change called IDH1. It may be an option if you have AML or MDS with that mutation and are recovering from transplant.
AachenAges 18–75 - NCT06726642Recruiting
Blood test study for people with inherited cancer risk
This study looks for DNA fragments in blood of people with certain inherited cancer syndromes. It may help find cancer earlier or guide better monitoring. You would give blood samples every 4 months (if in the experimental group).
Vancouver, British ColumbiaAges Up to 90 years - NCT06713083Recruiting
Physical activity for high-risk pregnant women on bed rest
This study tests whether a physical activity program can help pregnant women who are hospitalized on bed rest due to high-risk pregnancy. It aims to improve their well-being and possibly their pregnancy outcomes.

5-Year imatinib after GIST surgery for high-risk patients
This study looks at taking imatinib (a targeted anti-cancer pill) for 5 years after your GIST tumor has been fully removed. It is meant to lower the chance that GIST comes back in people considered “high risk.”
Seoul, SeoulAges 20 years+ - NCT05334836Recruiting
Scan for fat in the pancreas and link it to cyst features
This study uses scans to measure how common “fatty change” is in the pancreas. It then looks at whether fatty change is related to specific features of pancreatic cysts (and may also include healthy people).
Shatin, New TerritoriesAges 18 years+ - NCT05135975RecruitingPhase 2
Cabozantinib maintenance to help stop pediatric cancer from growing
This trial studies cabozantinib given after standard treatment to try to keep high-risk pediatric solid tumors from coming back or getting worse. It is offered to children and young adults whose cancer has not fully disappeared but is not progressing at the start of this maintenance phase.
Birmingham, AlabamaAges 1.5 years–40 years - NCT05984537RecruitingPhase 4
Bivalirudin during angioplasty for high-risk heart plaques
This study tests whether a blood thinner called bivalirudin, given during a procedure to open blocked heart arteries (PCI), helps blood flow better in the tiny vessels of the heart afterward. It is for people with a recent unstable heart condition and a high-risk plaque seen on a CT scan.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06682728RecruitingPhase 2
Treating high-risk bladder cancer after surgery
This trial tests a combination of two drugs (sacituzumab govitecan and nivolumab) given after surgery to prevent the return of muscle-invasive bladder cancer. It is for patients whose cancer has a high chance of coming back despite surgery.
Orange, CaliforniaAges 18 years+ - NCT06692556RecruitingPhase 3
Radiation vs monitoring for high-risk skin cancer
This trial compares two strategies after surgery for a type of skin cancer (cutaneous squamous cell carcinoma) that has a high chance of coming back. One strategy gives radiation therapy to the area, while the other just watches and checks for any signs of recurrence. The goal is to see if radiation can prevent the cancer from returning.
Le Puy-en-Velay, Auvergne-Rhône-AlpesAges 18 years+ - NCT06687772RecruitingPhase 2
Preventing brain relapse in high-risk lymphoma with stem cell transplant
This trial tests if high doses of chemotherapy (thiotepa and carmustine) followed by a stem cell transplant from your own cells can prevent lymphoma from coming back in the brain or spinal cord. It's for people with aggressive lymphoma that has a higher risk of spreading to the central nervous system.
St Louis, MissouriAges 18–75 - NCT06492460RecruitingPhase 3
Two courses of chemo-radiation after surgery for high-risk head and neck cancer
This trial tests whether giving two rounds of cisplatin chemo along with radiation after surgery can help people with high-risk head and neck squamous cell carcinoma. It is for patients who have already had surgery and whose cancer showed signs of being more aggressive.
Guangzhou, GuangdongAges 18–70 - NCT06672302Recruiting
Blood test to find high breast cancer risk
This study uses a blood test to help identify women who are at high risk for breast cancer. It is for Korean women aged 40 or older who have a suspicious breast finding and need a biopsy.
Honolulu, HawaiiAges 40 years+ - NCT06678126RecruitingPhase 2
Adaptive vs standard radiation for prostate cancer
This trial compares two ways of giving radiation to the prostate and pelvic lymph nodes. It also tests two different instructions for how full your bladder should be during treatment. The goal is to see which approach works better and is easier for patients.
Vancouver, British ColumbiaAges 18 years+ - NCT06672081Recruiting
Early catheter treatment for high-risk pulmonary embolism
This study tests whether using a catheter (a thin tube) to remove blood clots from the lungs early can help people with a severe, life-threatening pulmonary embolism. It is for patients who are in shock or have had a cardiac arrest due to a large clot.
Bad KrozingenAges 18 years+ - NCT06667700RecruitingPhase 3
A study of the antiviral molnupiravir for high-risk people with COVID-19

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.
