ZS801 for adults with severe hemophilia B
This trial studies ZS801, a gene therapy, in adults with hemophilia B who have very low natural FIX (a clotting protein) and frequent bleeding or joint problems. It aims to see how well it works and whether it is safe, especially by monitoring blood counts, infections, and immune responses.
Tianjin, Tianjin MunicipalityAges 18–65 - NCT05631886RecruitingPhase 1
Testing a cancer vaccine plus immune therapy for hard tumors
This early-phase trial tests whether combining a lab-made CAR-DC cancer vaccine with immune checkpoint medicines can shrink tumors that have specific genetic changes. It’s meant for people with advanced or returning (relapsed) solid tumors or certain lymphomas that match required tumor markers.
Beijing, Beijing MunicipalityAges 18–75 - NCT05633615RecruitingPhase 2
Testing new drug options after CAR T for aggressive lymphoma
This Phase 2 study tests whether adding or switching drug treatments after CAR T-cell therapy can improve outcomes for people with certain aggressive lymphomas that have come back or did not respond. It mainly looks at who remains disease-stable/partly improved after CAR T and what treatment approach works best next.
Tucson, ArizonaAges 18 years+ - NCT05634928Recruiting
Database study for patients with blood clotting signs
This trial builds a database to study patterns in blood tests and blood smear findings that can suggest small blood clots in the body. Joining may help researchers learn how to recognize and track these changes over time.
Suzhou, JiangsuAges Any age - NCT05635162RecruitingPhase 2
Zanubrutinib plus rituximab for slow-growing mantle cell lymphoma
This trial studies whether combining zanubrutinib and rituximab can better control indolent (slow-growing) mantle cell lymphoma. It aims to improve how long participants can stay without the lymphoma worsening.
DerbyAges 18 years+ - NCT05636514RecruitingPhase 1
Testing epigenetic and sensitizer treatment for AML and MDS
This early-phase trial tests whether a combination of targeted medicines can improve outcomes in people with higher-risk MDS or certain types of AML or CMML. It’s designed to find the safest dose and learn if the treatment can help the cancer respond.
Sydney, New South WalesAges 18 years+ - NCT05636787RecruitingPhase 2
Treosulfan chemo for myeloma before stem cell transplant
This trial tests whether the chemotherapy medicine treosulfan (Trecondi® Ideogen) works well and is safe for people with myeloma who are moving on to high-dose chemotherapy plus their own stem cell transplant. It may help strengthen the transplant “conditioning” treatment before the transplant.
BernAges 18–75 - NCT05640102Recruiting
Study of zanubrutinib in Waldenström macroglobulinemia
This is an observational study that follows people with Waldenström macroglobulinemia (WM) to learn how well zanubrutinib works and how safe it is. Your results will be tracked in relation to your disease features, including a blood/marrow marker called MYD88.
Huntsville, AlabamaAges 18 years+ - NCT05640843Recruiting
Plant-based diet study for MGUS or smoldering myeloma
This trial tests whether a whole-food, plant-based eating pattern—plus supplements or placebo—can improve health outcomes in people with MGUS or smoldering multiple myeloma. You may be asked to follow specific recipes and stop certain supplements, so it helps to confirm you can stick with the plan.
Atlanta, GeorgiaAges 18 years+ - NCT05641142Recruiting
Testing blood thinners in adults with inherited bleeding vessel disease
This study looks at people with Rendu-Osler (hereditary hemorrhagic telangiectasia) who have just started blood-thinning medicines. It aims to understand how antiplatelet and/or anticoagulant therapy affects safety and outcomes soon after starting.
AngersAges 18 years+ - NCT05641428RecruitingPhase 2
Testing a made-at-bedside CAR T cell for relapsed lymphoma
This Phase 2 study compares a “point-of-care” CAR T-cell treatment made at the hospital right away versus standard commercial CAR T-cells. It’s for adults with relapsed or refractory large B-cell lymphoma (a type of blood cancer) to see which approach works best and is safe.
AmsterdamAges 18 years+ - NCT05641610RecruitingPhase 1/Phase 2
Study drug for adults with hemophilia B who still bleed
This Phase 1/2 study tests ZS801, a gene-related treatment, to see how safe it is and whether it helps prevent bleeding in adults with hemophilia B. You may be considered if you’ve had frequent bleeds or joint problems and meet several lab and health requirements.
Tianjin, Tianjin MunicipalityAges 18 years+ - NCT05641961Recruiting
Mobile app for childhood cancer survivors’ long-term follow-up
This study tests a smartphone or tablet app that helps childhood cancer survivors (or their caregivers) manage long-term follow-up care. If you attend the UCSF Survivorship Clinic, the app may make it easier to understand what care you need and stay on track.
San Francisco, CaliforniaAges Any age - NCT05642884Recruiting
Pre-surgery program for older adults getting stem cell transplant
This study checks whether a “pre-surgery” health coaching program is practical and safe for older people with multiple myeloma who are scheduled for an autologous stem cell transplant. It may help patients prepare better for transplant recovery, and the study will see if the plan can be carried out smoothly.
Birmingham, AlabamaAges 60 years+ - NCT05643235Recruiting
Loop monitor to watch heart rhythms when starting a BTK inhibitor
This study checks how often abnormal heart rhythms happen when you start a BTK inhibitor (used for certain blood cancers). It uses a small implanted heart monitor to record your rhythm continuously before and after starting the medication, so doctors can detect and manage problems early.
New Hyde Park, New YorkAges 18 years+ - NCT05643742RecruitingPhase 1/Phase 2
Study of CTX112 for B-cell cancers that came back or did not respond
This Phase 1/2 study tests how safe and effective CTX112 is for adults whose B-cell cancer has returned or is not responding to treatment. It aims to see whether CTX112 can control the cancer while monitoring side effects closely.
Westwood, KansasAges 18 years+ - NCT05643651RecruitingPhase 4
Rivaroxaban for kids with large heart artery aneurysms after Kawasaki disease
This trial studies whether rivaroxaban (a blood thinner) can help prevent dangerous clots in children age 2 and older who have “giant” coronary artery aneurysms after Kawasaki disease. Doctors will see if it’s safe and tolerable for children who are also on standard anti-clot/anti-platelet medications for the next 3 months.
Shanghai, Shanghai MunicipalityAges 2–18 - NCT05645510Recruiting
Study for people on long-term cancer targeted medicines

Blood test study to predict stroke risk after TIA
This trial studies tiny particles in your blood (called extracellular vesicles) to understand and predict stroke risk after a TIA (a temporary stroke-like episode). It may help doctors identify who is at higher risk using blood samples, rather than only symptoms and scans.
Merthyr TydfilAges 18 years+ - NCT05645718RecruitingPhase 2
Chemo plus targeted antibodies for relapsed childhood B-ALL
This Phase 2 study tests a combination treatment for children, teens, or young adults whose B-cell acute lymphoblastic leukemia (B-ALL) has come back or did not respond to initial therapy. It may help patients who cannot safely receive certain standard medicines like anthracyclines or who cannot tolerate PEG-asparaginase.
Houston, TexasAges 1–25 - NCT05646576Recruiting
Palliative care support during blood cancer cell therapy
This trial studies whether adding palliative care (comfort-focused care to reduce stress and symptoms) helps people during adoptive cell therapy for blood cancers. It may help improve quality of life while you’re receiving the therapy.
Boston, MassachusettsAges 18 years+ - NCT05648019RecruitingPhase 2
CD19 CAR T-cell therapy for tough B-cell blood cancers
This Phase 2 study tests a one-time CAR T-cell treatment aimed at CD19, a target found on many B-cell leukemias and lymphomas. It’s for people whose disease has come back or hasn’t responded to prior treatments, or who can’t have a stem cell transplant.
