Elranatamab for multiple myeloma that has come back
This trial tests a new drug called elranatamab (given as an outpatient, not in the hospital) for people with multiple myeloma that has come back or stopped responding to several treatments. The goal is to see if taking it less often works well and is safer.

Ziftomenib maintenance after stem cell transplant for AML
This trial tests if the drug ziftomenib can help prevent AML from coming back after a stem cell transplant. It is for people who have certain gene changes (KMT2A rearrangement or NPM1 mutation) and are in remission or near-remission before transplant.
Boston, MassachusettsAges 18 years+ - NCT06430788RecruitingPhase 2
Emapalumab for children with severe aplastic anemia
This trial tests whether a medication called emapalumab can help children with severe aplastic anemia, a condition where the bone marrow stops making enough blood cells. It combines emapalumab with standard immune-suppressing therapy to try to improve blood cell counts.
New York, New YorkAges birth–25 years - NCT06432387Recruiting
Blood clotting changes during complex aneurysm repair
This study looks at how blood clotting factors change during a complex aneurysm repair. It may help doctors better understand and manage bleeding risks.
Larissa, ThessalyAges 18 years+ - NCT06439199Recruiting
Blood protein study in non-intensive chemotherapy for AML and MDS
This study looks at certain proteins in the blood (called FLT3 ligand and IL6) of people being treated for blood cancers like AML, MDS, or CMML. The goal is to understand how these proteins change during non-intensive chemotherapy, which may help doctors better personalize treatment.
Nantes, Loire-AtlantiqueAges 18–99 - NCT06424340RecruitingPhase 1/Phase 2
Cell therapy for relapsed or refractory AML with NPM1 mutation
This trial tests a new type of cell therapy, called MB-dNPM1-TCR.1, for people with acute myeloid leukemia (AML) that has returned or not responded to standard treatments. The therapy uses your own immune cells, which are specially trained to find and attack leukemia cells that have a specific mutation in the NPM1 gene.
LeidenAges 18 years+ - NCT06428019RecruitingPhase 3
Comparing drug combinations for untreated CLL or SLL
This trial tests two different drug combinations (venetoclax with obinutuzumab or with acalabrutinib) to see how they affect the risk of tumor lysis syndrome in people with untreated CLL or SLL. It may help find the safest and most effective way to start treatment.
Tucson, ArizonaAges 18 years+ - NCT06433947RecruitingPhase 1
Testing an experimental drug OPN-6602 for advanced multiple myeloma
This trial tests an experimental oral drug called OPN-6602 for people with multiple myeloma that has come back or stopped responding to at least three prior treatments. The main goal is to see if the drug is safe and tolerable, and to find the best dose.
Gilbert, ArizonaAges 18 years+ - NCT06423911RecruitingPhase 3
Study of olverembatinib for people with chronic phase CML
This study tests a new targeted drug called olverembatinib for people with chronic myeloid leukemia (CML) that has stopped responding to other treatments. It aims to see if the drug can control the leukemia with fewer side effects.
Birmingham, AlabamaAges 18 years+ - NCT06422078Recruiting
Real-world study of Benralizumab for severe asthma
This study is for people with severe eosinophilic asthma who are about to start a medicine called Benralizumab (Fasenra). It will observe how the medicine works in real life, and requires you to answer some questions about your asthma every week and month.
AhrensburgAges 18–120 - NCT06439082RecruitingPhase 3
Crizanlizumab for sickle cell pain crises
This trial tests whether crizanlizumab can reduce painful sickle cell crises (called vaso-occlusive crises or VOCs) in people with sickle cell disease who have frequent crises. It may be an option for those who still have crises despite current treatments.
Birmingham, AlabamaAges 12–100 - NCT05658640RecruitingPhase 1/Phase 2
Testing trametinib and steroid plus chemo for relapsed blood cancers
This early-phase trial tests whether adding trametinib and dexamethasone to standard chemotherapy can improve outcomes for children whose blood cancer has come back or did not respond. Because it is a Phase 1/2 study, the main goal is to see safety and learn the best way to treat your specific cancer type.
