Recruiting studies
- NCT04453826RecruitingPhase 3
Test PD-1 plus chemo-radiation for high-risk nasopharyngeal cancer
This Phase 3 trial tests whether adding a PD-1 immunotherapy (given with chemotherapy and radiation, and also after) can improve outcomes for people with high-risk nasopharyngeal cancer. It may help by strengthening the immune system’s attack on the cancer alongside standard treatment.

This trial studies a treatment approach (a combination given through the liver) for people with early liver cancer that can be surgically removed but has a high chance of coming back. It may help reduce the risk of recurrence after treatment.
Guangzhou, GuangdongAges 18–75 - NCT04700332RecruitingPhase 2
Test of PyL PET/CT for high-risk or returning prostate cancer
This Phase 2 study checks how well a scan called PyL PET/CT can help find prostate cancer that is high-risk or has come back by blood test. The goal is to improve how doctors detect spread and guide the next treatment steps.
Irvine, CaliforniaAges 18 years+ - NCT04476485Recruiting
Predicting breast cancer recurrence after extended hormone therapy
This trial looks at factors that may predict whether hormone receptor–positive breast cancer will come back after you’ve already completed 5 years of hormone (endocrine) therapy. It may help identify who benefits most from longer treatment and follow-up.
Harbin, HeilongjiangAges 18–70 - NCT05080010RecruitingPhase 3

This Phase 3 study tests whether giving chemotherapy after the eye has been removed can lower the chance of retinoblastoma coming back for children with high-risk disease. You may be screened if your child had one eye affected and meet the staging and treatment history requirements.
Guangzhou, GuangdongAges Any age - NCT05086614RecruitingPhase 3
Thymosin-alpha 1 after surgery for high-risk colon cancer
This trial looks at whether thymosin-alpha 1, an immune-support treatment, can help prevent colon cancer from coming back after surgery. It targets people with high-risk stage II or III colon cancer who have had the tumor removed.

Dinutuximab beta plus chemo for childhood neuroblastoma after relapse
This Phase 1 trial tests a combination of dinutuximab beta (an immunotherapy) and chemotherapy in children with high-risk neuroblastoma that did not respond to standard treatment or has come back or progressed. It aims to see how well the treatment works and how safely it can be given in this situation.
Krakow, MalopolskaAges 1–18 - NCT04894188Recruiting
Hormone plus radiation before prostate surgery for high-risk cancer
This trial studies giving hormone treatment and radiation before prostate surgery to treat high-risk, locally advanced prostate cancer. It aims to improve cancer control by shrinking or controlling the tumor before removing it.

Chemo tablets with or without an immune therapy after cancer treatment
This trial tests whether taking the chemo tablet capecitabine after standard chemoradiation can help prevent cancer from coming back, and whether adding an immune therapy (a PD-1 antibody) improves results. It is for people with high-risk nasopharyngeal (throat) cancer whose main treatment has already finished.
Guangzhou, GuangdongAges 18–65 - NCT03753243RecruitingPhase 2
Pembrolizumab and hormone blocker before prostate surgery
This Phase 2 trial studies whether pembrolizumab plus a hormone “androgen axis” blocker taken before prostate surgery can improve outcomes for people with high-risk, non-metastatic prostate cancer. It’s designed for patients who are planning prostate removal with an extended lymph node dissection.
Portland, OregonAges 18 years+ - NCT05455918RecruitingPhase 2
Chemo with paclitaxel, ifosfamide, and cisplatin for high-risk germ cell tumors
This Phase 2 trial tests a specific chemotherapy combination (paclitaxel, ifosfamide, and cisplatin) for children and teens with newly diagnosed, high-risk germ cell tumors. It aims to improve outcomes by treating cancer cells with a stronger chemo plan.
SeoulAges 1–20 - NCT03280511RecruitingPhase 2
After surgery chemo sprayed into the abdomen for high-risk colon cancer
This Phase 2 study tests whether spraying chemotherapy into the abdomen (through a small procedure) after colon cancer surgery can lower the chance the cancer comes back. It is meant for people with high-risk tumor features but who have had surgery and have no proven relapse yet.
OdenseAges 18 years+ - NCT03848962Recruiting
Share leftover or collected samples for research
This study helps collect and share human samples (like blood or other specimens) so researchers can do new studies. It’s mainly about providing samples for research use, not testing a treatment on you.
Huntsville, AlabamaAges 1 month–89 years - NCT04472845Recruiting
Shorter or longer breast radiation after surgery for high-risk cancer
This trial compares two schedules of radiation after breast surgery in people with high-risk, node-positive breast cancer. The goal is to see whether giving radiation in 1 week or 2 weeks works well and is safe after standard treatments.
ChandigarhAges 18 years+ - NCT05682755RecruitingPhase 1/Phase 2
Chidamide to Prevent AML Return After Bone Marrow Transplant
This Phase 1/2 study tests whether chidamide can help prevent high-risk acute myeloid leukemia (AML) from coming back after an allogeneic bone marrow transplant (allo-HSCT). Participants must already be in complete remission and have recovered blood counts after transplant.
Chengdu, SichuanAges 18–65 - NCT05686434RecruitingPhase 2
Osimertinib after surgery for early-stage EGFR-mutated lung cancer
This trial tests osimertinib (a targeted pill) given after surgery to help prevent early-stage lung cancer from coming back. It’s for people with fully removed, high-risk stage I non-small cell lung cancer that has specific EGFR gene changes.
Tianjin, Tianjin MunicipalityAges 18 years+ - NCT05707819Recruiting
Sintilimab plus chemoradiotherapy for high-risk nasopharyngeal cancer
This trial tests whether adding sintilimab (an immune treatment) to standard chemoradiotherapy can improve outcomes for people with high-risk, locally advanced nasopharyngeal (throat) cancer. It may help your immune system work better against the cancer alongside radiation and chemotherapy.

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.
