Bethesda, MarylandAges 3–39 - NCT05444712Recruiting
Stem cell transplant after best response in some T-cell lymphomas
This trial studies whether doing an autologous stem cell transplant (using your own stem cells) after a complete response helps people with certain T-cell lymphomas stay in remission longer. It may be an option if your lymphoma has shrunk completely and you fit the safety and testing requirements.
AmiensAges 18–70 - NCT05445011RecruitingPhase 1
FLT3-targeted CAR-T for relapsed or resistant AML
This trial tests an engineered immune cell treatment (CAR-T) made to target FLT3, for adults with acute myeloid leukemia (AML) that has come back or did not respond to standard treatment. It aims to control the leukemia when options have been limited.
Wuhan, HubeiAges 18–70 - NCT05447442Recruiting
Use a pre-surgery plan to treat anemia before an operation
This trial looks at whether following a hospital guideline to treat anemia before surgery helps patients have better pre-op care. You may be eligible if you have anemia found during a pre-anesthesia clinic visit.
Bangkok, BangkokAges Any age - NCT05449834RecruitingPhase 3
Testing early fibrinogen treatment after serious trauma bleeding
This Phase 3 study tests whether giving fibrinogen early can improve outcomes for adults with serious trauma who are actively bleeding. The goal is to help blood clotting work better sooner and potentially reduce complications from uncontrolled bleeding.
Newcastle, New South WalesAges 18–100 - NCT05451979Recruiting
Exercise training at home for kids after heart transplant
This trial tests a home-based, short bursts exercise program (HIIT using the MedBIKE™ system) for children who had a heart transplant at least 6 months ago. It may help improve fitness and safety after transplant, while checking which kids can participate without heart rhythm or symptom problems.
Edmonton, AlbertaAges 10–18 - NCT05454774RecruitingEarly Phase 1
Gene therapy for adults with severe hemophilia A
This early-phase study tests an FVIII gene therapy to help your body make more of the missing clotting factor in hemophilia A. It’s aimed at adults with severe low FVIII levels who have already used FVIII replacement products for a long time and have not developed an immune blocker (an inhibitor).
Tianjin, Tianjin MunicipalityAges 18 years+ - NCT05462704RecruitingPhase 3
IV or oral iron to treat anemia in pregnancy
This trial compares giving iron through a vein (IV) versus by mouth (oral) to treat iron-deficiency anemia during pregnancy. It may help you and your baby by finding which method works better and fits safely during mid-pregnancy.
Birmingham, AlabamaAges 18–45 - NCT05463263RecruitingPhase 1/Phase 2
Study drug for adults with relapsed or treatment-resistant lymphomas
This Phase 1/2 study tests dencatistat (STP938) to treat adults whose B-cell or T-cell lymphoma has come back or not responded to treatment. It looks at safety, the best dose, and whether it can shrink tumors or improve disease control when standard options have not helped.
Denver, ColoradoAges 18 years+ - NCT05463133RecruitingPhase 1/Phase 2
Stem cell transplant for CGD using targeted medications and steroids-free support
This trial tests an intensive stem cell transplant approach for people with chronic granulomatous disease (CGD). The study aims to improve outcomes by preparing the body for a donor stem cell graft and using immune “brakes” to reduce immune problems.
Bethesda, MarylandAges 4–65 - NCT05464719RecruitingPhase 2
Loncastuximab for lymphoma patients in partial remission after CAR T
This trial studies loncastuximab tesirine (a targeted cancer medicine) given after CAR T-cell therapy when your lymphoma has improved to a partial remission. It aims to reduce the chance of the lymphoma returning after CAR T.
Houston, TexasAges 18 years+ - NCT05469893RecruitingPhase 2
Targeted treatment for high-risk smoldering myeloma
This trial studies a precision approach to treat people with high-risk smoldering myeloma (a condition that can turn into active myeloma). The goal is to see whether the treatment can slow or prevent progression and improve outcomes.
Denver, ColoradoAges 18 years+ - NCT05469945Recruiting
Prevention study for leg swelling after gynecologic cancer treatment
This study looks at what to do to help prevent or better manage leg swelling (lymphedema) after treatment for certain gynecologic cancers. You may be asked to use a diary or app and complete questionnaires so the team can track symptoms over time.
GhentAges 18–99 - NCT05472558RecruitingPhase 1
CAR-NK cell treatment for CD19-positive relapsed lymphoma
This Phase 1 study tests a new immune-cell treatment made from donated cord blood. It aims to treat people whose B-cell lymphoma has come back or did not respond, specifically when the tumor has CD19 on it.
Hanzhou, ZhejiangAges 18–75 - NCT05475600Recruiting
Biofeedback and relaxation for ICU patients with blood cancers
This trial tests whether guided biofeedback and relaxation techniques can help people with blood cancers while they are in the ICU. It may improve comfort and stress during critical illness, compared with standard care.
MetzAges 18–75 - NCT05476770RecruitingPhase 1
Tagraxofusp for children with CD123-positive leukemia
This study tests tagraxofusp, a medicine that targets a marker called CD123 on cancer cells, in children and young adults whose leukemia or lymphoma has come back or is resistant to treatment. It may help by shrinking the cancer and improving disease control after standard therapies have not worked.

Test drug DR-01 for specific blood cancer types
This early-phase study tests DR-01 to treat large granular lymphocytic leukemia (LGLL) or certain aggressive T-cell or cytotoxic lymphomas. It aims to see whether the drug is safe and can shrink or control the cancer.
Birmingham, AlabamaAges 18 years+ - NCT05477264RecruitingPhase 2
Tislelizumab with radiation for early nasal lymphoma
This trial tests whether adding a medicine called tislelizumab to radiation works better than radiation alone for newly diagnosed nasal (nasal-type) NK/T-cell lymphoma. If you qualify, it may help control the cancer and improve outcomes by using both treatments together.
SeoulAges 19 years+ - NCT05477563RecruitingPhase 3
One-time gene therapy for severe sickle cell and transfusion anemia
This trial tests a single dose of gene therapy (CTX001) to improve outcomes for people with severe sickle cell disease or transfusion-dependent beta-thalassemia. It aims to see how well it works and whether it is safe, especially after a planned stem cell transplant process.
