Study drug for CLL or SLL after prior treatment failure
This Phase 1 trial studies APG-2575 (alone or with other medicines) in adults with CLL/SLL whose disease came back or did not respond to earlier treatment. The goal is to learn the safest dose and whether it can shrink the leukemia and improve symptoms.
Duarte, CaliforniaAges 18–85 - NCT04184505RecruitingPhase 3
Testing stem cell transplant in higher-risk myelodysplastic syndrome
This Phase 3 trial tests whether doing an “allogeneic” stem cell transplant works best for people newly diagnosed with higher-risk MDS (a bone marrow disorder). It’s mainly for patients who are healthy enough to receive a transplant and haven’t started MDS treatment yet.
AlessandriaAges 18–70 - NCT04440436RecruitingPhase 1/Phase 2
IM19 study for relapsed or refractory non-Hodgkin lymphoma
This trial tests whether IM19 can safely and effectively treat non-Hodgkin lymphoma that has come back or did not respond to prior treatment. It is for adults with certain lymphoma markers and good overall functioning.
Beijing, Beijing MunicipalityAges 18 years+ - NCT04276870RecruitingPhase 2
CD19 gene-modified cells for high-risk B-cell leukemia
This Phase 2 trial studies CD19 “redirected” cells made from your own blood to treat certain high-risk or relapsed B-cell acute lymphoblastic leukemia (B-ALL). It may help by targeting cancer cells that carry a protein called CD19.
Philadelphia, PennsylvaniaAges birth–29 years - NCT04517656Recruiting
Testing blood markers after a bone marrow donor transplant
This trial checks how certain blood “biomarkers” change after you receive donor stem cells to rebuild your blood and immune system. The goal is to learn whether these markers can better predict your immune recovery after transplant.
Saint-EtienneAges 18 years+ - NCT04332341RecruitingEarly Phase 1
Nicotinamide riboside during bone marrow transplant
This trial studies whether a supplement called nicotinamide riboside (a vitamin-like product) can be given safely during allogeneic bone marrow transplant. It may help researchers understand how well it works and how it affects recovery for people getting a donor transplant.
Cleveland, OhioAges 18 years+ - NCT04022239RecruitingPhase 1/Phase 2
Bendamustine to prevent transplant immune complications
This early-phase study tests whether giving the drug bendamustine (with or without another chemo drug) can lower the risk of graft-versus-host disease (GVHD) after a stem cell transplant. GVHD is an immune reaction where the donor’s cells attack your body. If it works and is safe, it could improve outcomes after transplant.
Houston, TexasAges 18–70 - NCT04061421RecruitingPhase 1/Phase 2
Testing new medicine combos for bone marrow disease overlap syndromes
This early-phase trial studies a new treatment plan (decitabine-related medicine with other targeted drugs, depending on the arm) for adults with MDS/MPN overlap syndromes. It aims to improve control of the disease by targeting the abnormal bone marrow cells. Because it’s Phase 1/2, the main goal is to find safe dosing and see whether it helps responses.
Tampa, FloridaAges 18 years+ - NCT05724836Recruiting
Carotid artery narrowing treatment follow-up at clinic
This study follows people who are getting a procedure for carotid artery narrowing at the clinic. It aims to learn about outcomes after these treatments.
Jacksonville, FloridaAges 18 years+ - NCT03001921Recruiting
Practice add-on for people on hemodialysis
This trial is for people with end-stage kidney disease who are already receiving hemodialysis. It tests a “wise practice” program or approach during dialysis to see if it can help patients in some meaningful way.
Guangzhou, GuangdongAges 18 years+ - NCT02445222RecruitingPhase 3
Follow-up study for people treated with CAR-T therapy
This study checks how people do over the long term after receiving CAR-T, an advanced immune treatment. It may help doctors understand long-term safety and benefits, and what to expect after treatment.
Phoenix, ArizonaAges birth–100 years - NCT04725201RecruitingPhase 4
IV heparin study after finger or hand reattachment
This study looks at whether giving an IV blood thinner called unfractionated heparin after finger/hand reattachment and restoring blood flow improves healing and safety. If you were accepted into the CEVARMU replant/revascularization program, this trial may be testing a standard-after-surgery medicine approach.
Montreal, QuebecAges 14 years+ - NCT04920968RecruitingPhase 2
Obinutuzumab versus rituximab for newly diagnosed ALL
This Phase 2 study compares two antibody treatments—obinutuzumab and rituximab—for newly diagnosed acute lymphoblastic leukemia (ALL) that has the CD20 marker. It aims to see which treatment works better and is safe for people whose leukemia cells have CD20.
BialystokAges 18 years+ - NCT05290662Recruiting
Patient registry for people treated with oNKord®
This trial is a registry that collects information from people who received at least one dose of oNKord® in a clinical study. It may help researchers better understand what happens after treatment and support future research.
HanoverAges 18 years+ - NCT04918173RecruitingPhase 3
Atenativ for people with inherited low antithrombin during surgery or birth
This trial tests whether Atenativ (an antithrombin treatment) lowers dangerous blood clots during planned surgery or during late pregnancy/delivery. It’s for people with a rare inherited blood-clotting condition called congenital antithrombin deficiency.
Washington D.C., District of ColumbiaAges 12–80 - NCT05445154RecruitingPhase 1/Phase 2
New treatment for newly diagnosed FLT3 AML with oral drugs
This Phase 1/2 study tests SKLB1028 (with daunorubicin and cytarabine) in people with newly diagnosed acute myeloid leukemia (AML) who have an FLT3 mutation. It aims to see how well and how safely this treatment works for this specific type of AML.
ChengduAges 18–59 - NCT04083183RecruitingPhase 1/Phase 2
Testing radiation plus antibody therapy for certain non-cancer diseases
This early-phase study tests a conditioning treatment using total-body irradiation and a radioactive antibody (called astatine-211) before a stem cell transplant for non-cancer conditions. The goal is to improve how well the donor cells take hold and are tolerated.
Seattle, WashingtonAges 18–49 - NCT03850418RecruitingPhase 2
Azacitidine for blood chimerism changes after transplant
This Phase 2 study tests whether azacitidine can improve outcomes when donor blood “chimerism” starts dropping after an allogeneic stem cell transplant. It’s for people with AML, MDS, MPN, or CMML who are experiencing early warning signs in their blood counts after transplant but without clear relapse in the bone marrow.
Detroit, MichiganAges 18–75 - NCT04555785RecruitingPhase 4
Testing platelet treatment in ICU patients after surgery
This trial studies whether a platelet-related treatment can work better in people in the ICU who need a platelet transfusion after surgery. It may help reduce bleeding by improving how platelets work when certain blood clotting proteins are already high.
BaselAges 18 years+ - NCT04283006RecruitingEarly Phase 1
CAR T-cell treatment for hard-to-treat B-cell blood cancers
This early-phase trial tests a special kind of immune cell treatment (CAR T cells) that targets CD20 and CD22 in people with relapsed or refractory B-cell cancers. It may help by attacking cancer cells that survived prior treatments, but it is still being studied for safety and early effectiveness.
Hangzhou, ZhejiangAges 3–70 - NCT04237623RecruitingPhase 2
GM-CSF after transplant using a matched related donor
This Phase 2 study tests whether giving a medicine called GM-CSF after an allogeneic transplant (using a matched related donor) can improve outcomes. Participants must meet health and donor-matching requirements and be eligible to safely receive the treatment and consent to the study.
Atlanta, GeorgiaAges 18–78 - NCT04571203RecruitingPhase 1
Kidney transplant plus blood-cell treatment to help the graft settle
This Phase 1 study tests a treatment plan (including rabbit medicine and a low dose of radiation) meant to help the new kidney “take” and work longer. It also includes a kidney-from-deceased-donor process and checks how safely the treatment works in people with end-stage kidney disease.
Palo Alto, CaliforniaAges 18–65 - NCT04643002RecruitingPhase 1/Phase 2
Isatuximab added to other drugs for relapsed myeloma
This early-phase study tests isatuximab (an anti-cancer antibody) combined with other study medicines in people whose multiple myeloma has come back or not responded. It aims to improve control of the disease after you’ve already had multiple prior treatments.
Atlanta, GeorgiaAges 18 years+ - NCT04623424Recruiting
