Recruiting studies
- NCT04297592Enrolling by invitationPhase 4

Testing a stronger rituximab dose schedule for new ITP
This trial studies whether a “dose-dense” rituximab schedule can help children and teens with newly diagnosed, high-risk immune thrombocytopenia (ITP). It aims to raise/maintain platelet counts and control bleeding, while carefully checking safety.
Vahalla, New YorkAges 1–21 - NCT04333706RecruitingPhase 1/Phase 2
Sarilumab plus capecitabine for certain breast cancers
This trial studies whether adding sarilumab to capecitabine can shrink or control metastatic or high-risk breast cancer that lacks HER2 and is either triple-negative or hormone-resistant. It aims to find a safe dose first, then look at how well the treatment works compared with historical results.
Los Angeles, CaliforniaAges 18–99 - NCT04215731RecruitingPhase 3
Chemo plus targeted drug before surgery for high-risk rectal cancer
This trial tests giving chemotherapy (mFOLFOXIRI) plus bevacizumab before surgery for rectal cancer that has higher-risk features. It aims to shrink or control the cancer early to improve outcomes after treatment.
Guangzhou, GuangdongAges 18–70 - NCT04169737RecruitingPhase 2
Acalabrutinib and venetoclax for high-risk CLL or SLL
This trial tests whether acalabrutinib and venetoclax (with or without early obinutuzumab) can control chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). It is mainly for people whose disease is high-risk, has come back, or did not respond to earlier treatment.
Houston, TexasAges 18 years+ - NCT04031677RecruitingPhase 3
Surgery with or without chemotherapy for high-risk retroperitoneal sarcoma
This trial studies whether adding chemotherapy before surgery helps people with high-risk retroperitoneal (abdominal-area) leiomyosarcoma or liposarcoma. The goal is to improve outcomes while comparing surgery alone versus surgery plus neoadjuvant chemotherapy.
Birmingham, AlabamaAges 18 years+ - NCT04055818RecruitingPhase 1
Testing three medicines for high-risk sickle cell disease
This Phase 1 study tests whether nicotinamide, oral tetrahydrouridine, and decitabine can help people with high-risk sickle cell disease. It is mainly a safety-and-dosing study, but it also looks for signs the medicines may improve disease-related problems.
Chicago, IllinoisAges 18 years+ - NCT04116502RecruitingPhase 3
Ruxolitinib versus standard treatments for high-risk polycythemia vera
This Phase 3 study compares ruxolitinib against hydroxycarbamide or interferon as the first treatment for people with high-risk polycythemia vera. It aims to see which option works better to reduce disease-related problems and complications.
AberdeenAges 18 years+ - NCT04140487RecruitingPhase 1/Phase 2
Study drugs for certain FLT3-mutated blood cancers that have returned
This trial tests a combination of three medicines—azacitidine, venetoclax, and gilteritinib—in people with specific gene changes (FLT3 mutations) in leukemia and related bone marrow diseases that have come back or are hard to treat. The goal is to see if this drug combination can control the disease and improve outcomes.
Houston, TexasAges 18 years+ - NCT03937635RecruitingPhase 3
Lenalidomide and dexamethasone, with or without daratumumab
This phase 3 trial studies whether lenalidomide plus dexamethasone can prevent or delay progression of “high-risk smoldering” multiple myeloma, and whether adding daratumumab improves outcomes. It’s meant for people who are not yet showing symptoms, but whose lab and scan results suggest higher risk.
Birmingham, AlabamaAges 18 years+ - NCT03959085RecruitingPhase 3
Inotuzumab plus chemotherapy for high-risk childhood leukemia
This Phase 3 trial tests whether adding inotuzumab to standard post-induction chemotherapy improves outcomes for children and young teens with high-risk B-ALL, mixed phenotype acute leukemia (MPAL), or certain high-risk B-LLy. It may help by targeting leukemia cells more directly, but participation depends on specific age, lab results, and medical history rules.
Birmingham, AlabamaAges 12 months–25 years - NCT03970005Enrolling by invitation
Step-based program for teens with early signs of psychosis
This trial tests a staged (“step-based”) mental health program for people ages 12–25 who have early warning signs that could develop into psychosis. It may help by targeting symptoms early and reducing the chance of worsening over time.
Columbus, OhioAges 12–25 - NCT03729115Recruiting
Enhanced breast cancer screening for high-risk women
This study tests a more thorough breast cancer screening program using MRI and other imaging for women at high risk. It aims to detect cancer earlier, which may improve treatment options and outcomes.
La Jolla, CaliforniaAges 25 years+ - NCT03661307RecruitingPhase 1/Phase 2
Study of quizartinib, decitabine, and venetoclax for acute myeloid leukemia or high-risk myelodysplastic syndrome
This trial combines three drugs to treat certain types of leukemia or a related blood condition. It may be an option for people who cannot have standard intensive chemo, or for those whose disease has come back.
Houston, TexasAges 18 years+ - NCT03547414Recruiting
Urine markers to predict kidney injury worsening in septic shock
This study tests whether two substances in urine (TIMP2 and IGFBP7) can help doctors predict which patients with sepsis-related kidney problems will get worse. If these markers work, doctors could identify high-risk patients earlier and treat them more aggressively.
AmiensAges 18 years+ - NCT03689595Enrolling by invitation
PROMISE study: Predicting myeloma risk in high-risk groups
This study uses a blood test to find early signs of myeloma in people at higher risk, such as those with a family history or African ancestry. It aims to predict who might develop myeloma before symptoms appear.
Boston, MassachusettsAges 30 years+ - NCT03589729RecruitingPhase 2
Dexrazoxane to help protect the heart during blood-cancer chemo
This Phase 2 study tests dexrazoxane, a heart-protecting medicine, to reduce heart side effects from chemotherapy in people with certain blood cancers. If you qualify, you would receive dexrazoxane along with chemotherapy, and the team will monitor your heart function closely.
Houston, TexasAges 12 years+ - NCT03583710RecruitingPhase 3
Mitotane after adrenal tumor surgery, with or without chemo
This study looks at whether giving mitotane after surgery (and possibly adding cisplatin/etoposide chemotherapy) helps prevent adrenal cancer from coming back. It is for people with stage I–III adrenal cortical cancer who have a high risk of relapse after their tumor was removed.
Ann Arbor, MichiganAges 18 years+ - NCT03590171RecruitingPhase 2
Study for children with relapsed high-risk ALL
This Phase 2 study tests a treatment approach for children with high-risk ALL that has returned. It aims to improve outcomes after relapse by using a planned treatment schedule.

Targeted iodine therapy, then donor transplant for hard leukemias
This trial tests an antibody-linked radioactive iodine treatment, followed by a donor stem cell transplant, for people with relapsed or refractory high-risk acute leukemia or certain MDS. It may help patients by targeting leukemia cells and then using a new immune system to control the disease.
Seattle, WashingtonAges 18–75 - NCT03126916RecruitingPhase 3
Testing added therapy for high-risk neuroblastoma in children
This Phase 3 study tests whether adding either a targeted drug (lorlatinib) or a radioactive treatment (131I-MIBG) to intensive chemotherapy improves outcomes for children with high-risk neuroblastoma. It may help by aiming at tumor cells more directly alongside standard treatment.
Birmingham, AlabamaAges 12 months–30 years - NCT03128034RecruitingPhase 1/Phase 2
Astatine-211 treatment before stem cell transplant for high-risk blood cancers
This trial tests a targeted radiation drug (Astatine-211) given before a donor stem cell transplant for people with high-risk leukemia or certain bone-marrow cancers. The goal is to better control the cancer before the transplant.
Seattle, WashingtonAges 18–75 - NCT03250078Recruiting

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.
