Prevention and early detection for people at high cancer risk
This study looks at surveillance (watching closely), prevention, and early “interception” steps to lower the chance that cancer will develop or be found later. It is for people with genetic risk, past cancer treatment exposures, strong family history, or certain early pre-cancer or high-risk conditions.

Philadelphia, PennsylvaniaAges birth–29 years - NCT05500807RecruitingPhase 1
Emicizumab study for severe von Willebrand disease or overlap disorder
This Phase 1 trial studies how well and safely emicizumab works for people with severe von Willebrand disease (VWD) or VWD plus hemophilia A. Emicizumab is a preventive medicine given regularly to reduce bleeding risk.
Orange, CaliforniaAges birth–90 years - 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+ - NCT05485155RecruitingPhase 2
Zemaira trial for adults with eosinophilic esophagus
This Phase 2 study tests Zemaira (an alpha-1 antitrypsin treatment given through an IV) to see if it improves eosinophilic esophagitis (EoE) in adults. You may be able to help researchers learn whether this treatment can reduce EoE activity when standard treatments haven’t worked.
Bethesda, MarylandAges 18–70 - NCT05501756RecruitingPhase 2
Dose-tuning alemtuzumab for children before a stem cell transplant
This Phase 2 study looks at the best dose of alemtuzumab (a medicine used before transplant) for children undergoing a donor stem cell transplant for a non-cancer illness. It may help doctors fine-tune dosing to improve how the drug behaves in the body and make future transplant care more precise.
Cincinnati, OhioAges Any age - NCT05483010RecruitingPhase 2
Testing statins to treat low-risk blood disorders with abnormal blood counts
This Phase 2 trial studies whether a statin medicine can help people with CCUS (a bone-marrow condition with abnormal genetic mutations) or lower-risk MDS (a blood disorder) that causes persistent low blood counts. It aims to see if statins can improve blood-related outcomes while keeping you safe from side effects.
St Louis, MissouriAges 18 years+ - NCT05255003RecruitingPhase 4
Anticoagulation options for low platelets with cancer blood clots
This trial studies how best to prevent and treat dangerous blood clots in people with cancer who also have very low platelets. It may help guide safer blood-thinner treatment when bleeding risk is high.
Edmonton, AlbertaAges 18 years+ - NCT05171478Recruiting
