Recruiting studies
- NCT06859801Recruiting
Bone pain study combining ablation and radiation
This study looks at combining two treatments for painful bone tumors that have spread from other cancers. It tests if using both treatments together provides better pain relief than either alone.
San Diego, CaliforniaAges 21 years+ - NCT06830720Recruiting

This study looks at how well Kisqali (ribociclib) combined with hormone therapy works after surgery for people with early-stage HR+ HER2- breast cancer that has a high chance of coming back. It aims to gather real-world data on different treatment options.
Wiener Neustadt, Lower AustriaAges 18–100 - NCT06830798RecruitingPhase 3
Ravulizumab to prevent delayed graft function after kidney transplant
This study tests an investigational medicine (ravulizumab) given through a vein to see if it can prevent delayed graft function—meaning the new kidney takes longer to start working—after a high-risk kidney transplant. It is for adults on dialysis who are getting a kidney from a donor whose heart stopped or who is considered high-risk.
Phoenix, ArizonaAges 18 years+ - NCT06835049RecruitingPhase 2
Heating therapy before surgery for high-risk soft tissue sarcoma
This trial tests a new approach for high-risk soft tissue sarcoma of the arm, leg, or trunk. Before surgery, you would receive chemotherapy combined with local hyperthermia (a treatment that gently heats the tumor area) to see if this can improve outcomes.
AarauAges 18 years+ - NCT06826859RecruitingPhase 1/Phase 2
Daily aspirin vs split dosing to prevent preeclampsia
This study compares taking a daily low-dose aspirin (a single pill) versus splitting the same dose into two smaller pills many hours apart to see which way better prevents preeclampsia in pregnant people who are at higher risk.
Philadelphia, PennsylvaniaAges 16–55 - NCT06816121Recruiting
Blood test for early lung cancer in high-risk smokers
This study is evaluating a blood-based test that might detect lung cancer early, before symptoms appear. Researchers are looking for heavy smokers who have no signs of cancer, as well as those with suspicious lung nodules or confirmed lung cancer, to see if a simple blood draw could help identify cancer sooner.
Oklahoma City, OklahomaAges 30–80 - NCT06816134RecruitingPhase 2
TmBU chemo before stem cell transplant for high-risk leukemia
This clinical trial tests a new combination of chemotherapy drugs (called TmBU) before a stem cell transplant for people with high-risk or relapsed acute leukemia. The goal is to see if this conditioning regimen works better and is safe for patients who need a transplant.
Suzhou, JiangsuAges 15–65 - NCT06819566RecruitingPhase 2
Preventing bleeding from enlarged veins in the esophagus
This study tests whether tying off high-risk veins in the esophagus before starting a common liver cancer treatment can prevent bleeding. It is for people with liver cancer that has spread but who have never had cancer treatment before.

Gemcitabine and Mitomycin for High-Risk Upper Tract Cancer
This trial tests a combination of two chemotherapy drugs, gemcitabine and mitomycin, given directly into the kidney or ureter through a thin tube. It is for people with a high-risk but non-invasive form of upper urinary tract cancer that has not spread into deeper tissues.
New Brunswick, New JerseyAges 18–99 - NCT06810583RecruitingPhase 1
Dalbavancin to prevent infections in children with high-risk leukemia
This trial tests whether an antibiotic called dalbavancin, given to prevent bacterial infections during chemotherapy-induced low white blood cell counts, is safe and works in children and young adults with certain types of leukemia. It may help reduce the risk of serious infections during treatment.
Memphis, TennesseeAges Up to 25 years - NCT06812598Recruiting
Extended letermovir to prevent CMV after stem cell transplant
This trial tests whether taking letermovir for a longer time can prevent CMV (a common virus) from reactivating in adults with certain risk factors after a donor stem cell transplant. If you're preparing for your first transplant and have a high-risk donor or conditioning, this study may be an option.
Suzhou, JiangsuAges 18 years+ - NCT06807606RecruitingPhase 2
Cord blood transplant after relapse from first transplant
This trial tests a second transplant using two donated umbilical cord blood units for people whose blood cancer returned after a first stem cell transplant. It aims to offer a potential cure for high-risk blood cancers.
Houston, TexasAges Up to 60 years - NCT06797635RecruitingPhase 2
Study of Patritumab Deruxtecan and Pembrolizumab for High-Risk Early Breast Cancer
This trial tests a combination of targeted therapies (patritumab deruxtecan plus pembrolizumab) along with other anticancer drugs for people with a high-risk type of early-stage breast cancer that is either triple-negative or has very low hormone receptors and is HER2-negative. The goal is to see if this approach can help prevent the cancer from coming back.
Santa Monica, CaliforniaAges 18 years+ - NCT06802146RecruitingEarly Phase 1
Early treatment for high-risk CCUS
This trial tests an early treatment for people with a condition called high-risk CCUS, where low blood counts and gene changes raise the risk of developing blood cancer. The goal is to see if intervening early can prevent or delay progression to leukemia or MDS.
Boston, MassachusettsAges 18 years+ - NCT06798558RecruitingPhase 2
Lu-PSMA before prostate surgery for high-risk cancer
This trial tests a treatment called Lu-177-PSMA-617 given before surgery for high-risk prostate cancer that has spread only to nearby lymph nodes. It aims to see if this approach helps control the cancer before the prostate is removed.
Washington D.C., District of ColumbiaAges 18 years+ - NCT06802315RecruitingPhase 2
Radiation therapy before stem cell transplant for high-risk blood cancers
This trial tests a precise type of radiation called intensity modulated total marrow irradiation before a stem cell transplant. It aims to destroy cancer cells while reducing side effects for patients with high-risk leukemia or myelodysplastic syndrome.
Chicago, IllinoisAges 18–65 - NCT06786234RecruitingPhase 2
STP938 for high-risk essential thrombocythemia
This trial tests a daily pill called STP938 (dencatistat) for people with high-risk essential thrombocythemia (ET) who cannot take or have stopped responding to hydroxycarbamide. The goal is to see if STP938 can safely lower your platelet count and control the condition.
Poitiers, New AquitaineAges 18 years+ - NCT06787456Recruiting

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.
