Recruiting studies
- NCT07033598RecruitingPhase 2
Pacritinib or hydroxyurea for advanced CMML
This trial tests whether pacritinib works better than hydroxyurea for people with advanced proliferative chronic myelomonocytic leukemia (CMML). It may help if your white blood cell count is high and you have an enlarged spleen, severe symptoms, or low platelets.
Tampa, FloridaAges 18 years+ - NCT05285917RecruitingPhase 3

This trial tests a way to use hydroxyurea more safely and effectively in children with sickle cell anemia. It may help doctors fine-tune dosing to reduce complications and side effects.
LuandaAges 6 months–12 years - NCT06093672RecruitingPhase 3
Comparing givinostat vs hydroxyurea for polycythemia vera
This study compares a new drug called givinostat to hydroxyurea (a standard treatment) for people with polycythemia vera, a blood disorder that increases the risk of clots. The goal is to see if givinostat works better and is safe.
Birmingham, AlabamaAges 18 years+ - NCT06464458Recruiting
Better hydroxyurea dosing for sickle cell patients
This trial checks whether monitoring hydroxyurea drug levels in the blood can help doctors find the best dose for sickle cell patients. It focuses on people with HbSS who have recently had a pain crisis or whose current dose isn't working.
StrasbourgAges 2–35 - NCT07177300RecruitingPhase 4
Hydroxyurea for sickle cell disease in children
This trial tests different ways to start hydroxyurea for children with sickle cell anemia. The goal is to find the safest and most effective approach to help manage symptoms and prevent complications.
Cincinnati, OhioAges 6 months+ - NCT06930352RecruitingPhase 2
Ziftomenib for newly diagnosed AML with NPM1 or KMT2A changes
This trial tests an oral drug called ziftomenib for people with a type of acute myeloid leukemia (AML) that has certain genetic changes (NPM1 mutation or KMT2A rearrangement) and who are not able to receive standard chemotherapy. The goal is to see if ziftomenib can help control the leukemia.
Columbus, OhioAges 18 years+ - NCT06761560RecruitingPhase 2/Phase 3
Hydroxyurea dosing for children with sickle cell anemia
This study looks at whether adjusting the dose of hydroxyurea based on drug levels in the blood works better than the standard approach for treating sickle cell disease in children. It aims to reduce side effects and improve treatment outcomes.
Montreal, QuebecAges 6 months–18 years - NCT03653338RecruitingPhase 1/Phase 2
Bone marrow transplant using donor blood to treat sickle cell
This trial tests a specific type of bone marrow transplant for people with sickle cell disease (or certain other blood disorders) who have had serious complications despite standard care. It aims to see if removing the patient’s immune cells and using a matched donor’s cells can improve outcomes and reduce complications.
Pittsburgh, PennsylvaniaAges 5–40 - NCT03511118Recruiting
Drug safety study for breastfeeding mothers and babies
This study measures how common medicines move through a breastfeeding parent’s milk and checks safety in both the parent and breastfed baby. It may help doctors use these medicines more safely while you continue breastfeeding.
La Jolla, CaliforniaAges Any age - NCT07190833RecruitingPhase 1
Study of a cancer-killing virus injection for solid tumors
This early-phase trial tests a cancer-killing virus (OTS-412) that is injected directly into tumors. It is for people with solid tumors that have not responded to standard treatments, including immunotherapy. The goal is to see if the virus can shrink or control the injected tumors.
BusanAges 19 years+ - NCT07507760RecruitingPhase 2
Oral decitabine plus ivosidenib for older AML patients
This trial tests a combination of two oral drugs (decitabine and ivosidenib) as a first treatment for older or frail adults with AML that has an IDH1 mutation. The goal is to see if this pill-only regimen is safe and effective without needing intensive chemotherapy.
AlbaceteAges 18 years+ - NCT06871410RecruitingPhase 1
Engineered immune cells for relapsed or refractory AML
This trial tests a new type of cell therapy called CD83 CAR T cells for people whose acute myeloid leukemia (AML) has come back or hasn't responded to treatment. These cells are designed to find and attack the leukemia cells while sparing healthy cells.
Buffalo, New YorkAges 18 years+ - NCT07616154RecruitingPhase 2
Gene-Matched Family Stem Cell Transplant for Severe Sickle Cell
This trial tests whether a stem cell transplant from a partially gene-matched family member can cure severe sickle cell disease in children and young adults. The transplant uses a new approach that may work even when a perfectly matched sibling isn't available, and it might help patients whose sickle cell is causing serious complications like strokes, organ damage, or frequent pain crises.
Memphis, TennesseeAges Up to 22 years - NCT07708714RecruitingPhase 1/Phase 2
Hydroxyurea study for teens with sickle cell anemia
This study tests how well a higher dose of hydroxyurea works for teenagers with sickle cell anemia living in areas where malaria is common. It looks at safety and how the treatment affects their daily lives.
KampalaAges 11–18 - NCT03500731RecruitingPhase 1/Phase 2
Lung and bone marrow transplant for lung and blood failure
This Phase 1/2 study tests a special lung-and-bone-marrow transplant approach for people with severe lung disease and bone marrow failure (low blood counts). The goal is to see if the treatment is safe and whether it can improve outcomes when standard long-term immune-suppressing medicines are a poor fit.
Pittsburgh, PennsylvaniaAges 18–60 - NCT04093986Recruiting
Using past pregnancy records from women with sickle cell
This study looks back at past pregnancy and breastfeeding experiences in women with sickle cell disease who took hydroxyurea. It aims to better understand how hydroxyurea exposure may affect pregnancy and baby outcomes.
Cincinnati, OhioAges Any age - NCT05526924RecruitingPhase 1
Phase 1 trial tests re-radiation plus immunotherapy and a cancer pill
This trial studies whether adding a checkpoint immunotherapy (tislelizumab) and a cancer pill (pamiparib) to radiation can better treat cancer that has come back in the head and neck. It’s for adults with previously treated, HPV-positive oropharynx tumors, usually without widespread spread.
Chicago, IllinoisAges 18 years+ - NCT05870475RecruitingPhase 2
Interferon plus ruxolitinib for hydroxyurea-resistant polycythemia vera
This Phase 2 trial tests a combination of pegylated interferon and ruxolitinib in adults with polycythemia vera who can’t tolerate hydroxyurea or don’t respond well to it. If you qualify, it may help control blood counts and disease symptoms when standard treatment hasn’t worked.
TianjinAges 18 years+ - NCT05953584RecruitingPhase 2
Etavopivat for preventing stroke risk in sickle cell children
This trial studies etavopivat to see if it can improve blood-flow measurements in the brain that predict future stroke risk in children with sickle cell disease. If you qualify, you would take the study medicine and be monitored with brain blood-flow testing.

What Hydroxyurea is being studied for
Conditions with recruiting Hydroxyurea studies.
Common questions
- Are there clinical trials studying Hydroxyurea?
- Yes. Clin2 currently lists 24 recruiting studies that include Hydroxyurea, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Hydroxyurea trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Hydroxyurea an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Hydroxyurea or a specific trial is right for you.
