Stem cell transplant with added T-cells for blood cancers
This Phase 1 study tests a stem cell transplant plan that uses donor T-cells that have been specially processed and then added back. It aims to see if this approach is safer and works better for children and adults with serious blood cancers who need a transplant.
Palo Alto, CaliforniaAges 1 month–45 years - NCT04644016RecruitingPhase 2
Cord blood transplant for children and young adults with blood cancers
This Phase 2 trial studies using a cord blood transplant after finding it is risky enough that standard treatment may not be sufficient. It may help certain children and young adults with specific leukemia, lymphoma, and some non-cancer blood/immune or inherited disorders who do not have a well-matched donor available in time.
New York, New YorkAges Up to 21 years - NCT04644211RecruitingPhase 2
Ruxolitinib for symptom control in certain blood cancer types
This Phase 2 study tests ruxolitinib (a targeted medicine) in people with essential thrombocythemia or polycythemia vera who still have troublesome symptoms. It aims to see whether it can reduce symptoms by changing disease activity and blood-related inflammation.
Boston, MassachusettsAges 18 years+ - NCT04645199Recruiting
Long-term follow-up study for blood and bone marrow diseases
This study is collecting long-term follow-up information from people diagnosed with certain blood and bone marrow conditions. It may help doctors understand what happens over time and improve future care, but you’re mainly contributing data rather than receiving a new treatment.
Tianjin, Tianjin MunicipalityAges Any age - NCT04646083Recruiting
Tests how far a scope can insert in the small bowel
This trial looks at how deeply doctors can safely insert a camera scope into the ileum (a part of the small intestine) during a procedure called retrograde enteroscopy. It may help improve how the exam is done for people whose small-bowel problem wasn’t fully found by usual tests.
El Paso, TexasAges 18–90 - NCT04647227RecruitingPhase 4
SEVENFACT® to reduce bleeding in hemophilia with inhibitors
This trial studies whether SEVENFACT® can reduce bleeding episodes in people with hemophilia A or B who have inhibitors (proteins that make standard treatments less effective). It also tests how well people can track bleeding and medicine use during the study.
Phoenix, ArizonaAges 12–100 - NCT04653324Recruiting
Registry for people with diagnosed food allergies
This registry aims to collect information from people who already have a diagnosed food allergy. Joining may help researchers better understand food allergy patterns and needs.
McLean, VirginiaAges Any age - NCT04656184RecruitingPhase 3
Anakinra vs IVIG for kids who don’t respond to first IVIG
This study compares two treatments—anakinra and IVIG—for children with Kawasaki disease who still have fever after their first standard IVIG treatment. It aims to find which option works better and is safer for “IVIG non-responders” who may be at risk for heart complications.
Le Kremlin-Bicêtre, Val De MarneAges 3 months–17 years - NCT04655092RecruitingPhase 3
Extension study for people finishing prior P1101 treatment
This is an “extension” trial for people who already completed a 52-week P1101 study and agreed to continue. It tests whether continuing P1101 after the original study is safe and beneficial for certain patients.
Toon-shi, EhimeAges 20 years+ - NCT04657861RecruitingEarly Phase 1
BCMA/TACI CAR-T for relapsed or refractory multiple myeloma
This early-phase study tests a CAR-T cell treatment made to target BCMA and TACI proteins in multiple myeloma. It may help people whose myeloma has come back or did not respond to prior treatments, especially after certain prior therapies.
Hangzhou, ZhejiangAges 18–75 - NCT04657822RecruitingPhase 4
Crizanlizumab rollover study for people with sickle cell disease
This study lets people with sickle cell disease who already finished a Novartis crizanlizumab trial continue treatment under a rollover plan. It’s designed for participants who benefited from crizanlizumab and completed the earlier study schedule without major ongoing side effects.
Birmingham, AlabamaAges 6 months–100 years - NCT04659616RecruitingPhase 1
Pemigatinib after standard chemo for newly diagnosed AML
This Phase 1 trial studies whether adding pemigatinib after standard “7+3” chemotherapy can improve outcomes in certain newly diagnosed acute myeloid leukemia (AML) patients. It aims to find a safe dose and see how well the drug works in a very specific AML genetic group.
Portland, OregonAges 18 years+ - NCT04662294RecruitingEarly Phase 1
CD70-targeted CAR T therapy for CD70-positive blood cancers
This trial tests a customized immune-cell treatment (CAR T) that targets CD70 on cancer cells in certain blood cancers. It may help people whose disease has returned or did not respond to standard treatments.
Hangzhou, ZhejiangAges Any age - NCT04664179RecruitingPhase 1
EBV immune-cell treatment for EBV-positive lymphoma
This Phase 1 study tests an immune-cell therapy made to recognize EBV (a common virus) in people whose lymphoma contains EBV. It may help control EBV-driven cancers, especially when standard treatment isn’t working or can’t be used.
Houston, TexasAges Any age - NCT04665674Recruiting
Study of adults with pulmonary Langerhans cell histiocytosis
This study follows adults with a specific lung condition to better understand how it behaves over time. If you have the right diagnosis, joining could help researchers learn what to expect and how to manage it.
ParisAges 18 years+ - NCT04665882Recruiting
Prediction tool for arm swelling after breast cancer surgery
This trial tests a prediction tool (a “nomogram”) to estimate who is at risk of developing breast cancer–related lymphedema, or long-term arm swelling, after surgery. If you fit the surgery and lymph node criteria, your information may help personalize follow-up and prevention.
Wuhan, HubeiAges 18–80 - NCT04669171RecruitingPhase 1/Phase 2
Vaccine treatment for slow-growing lymphoma, alone or combined
This trial tests a new vaccine medicine (EO2463) to treat indolent non-Hodgkin lymphoma (slow-growing lymphoma), either by itself or with other treatment. It may help your immune system recognize and attack lymphoma cells.
Boston, MassachusettsAges 18 years+ - NCT04670029RecruitingPhase 3
Testing an APA program to improve outcomes in large B-cell lymphoma
This Phase 3 trial studies whether an APA program (an added supportive program during care) can improve event-free survival for people with diffuse large B-cell lymphoma. It may help by supporting patients during standard first-line treatment so they do better over time.
BesançonAges 65 years+ - NCT04670874Recruiting
Quality of life in people with cutaneous lymphoma
This study asks people with cutaneous lymphoma to fill out a questionnaire about quality of life. The goal is to better understand how this illness affects day-to-day life and comfort.
Duarte, CaliforniaAges 18 years+ - NCT04671212Recruiting
Using discarded bone marrow from certain orthopedic surgeries
This study looks at bone marrow cells that would otherwise be discarded during some orthopedic surgeries. It may help researchers learn more about specific blood disorders (certain types of thalassemia and sickle cell–related conditions).
Memphis, TennesseeAges Any age - NCT04675918Recruiting
Registry for children’s in-hospital cardiac arrest
This study collects information about children (from 1 month to 18 years) who have a cardiac arrest while in the hospital. The goal is to better understand what happens during these emergencies and improve care in the future.
MadridAges 1 month–18 years - NCT04676048RecruitingPhase 1/Phase 2
Gene therapy study for adults with hemophilia A
This Phase 1/2 study tests a one-time gene therapy (ASC618) to help the body make clotting factor for people with hemophilia A. It may reduce bleeding and the need for factor infusions, but you must meet several safety and eligibility checks.
Little Rock, ArkansasAges 18 years+ - NCT04678401RecruitingPhase 1
Trial tests transplant using a half-matched donor for high-risk leukemia
This Phase 1 trial tests a special bone marrow transplant using a related “half-matched” donor (haploidentical), without a specific immune-suppressing medicine (“IS-free”). It’s for adults with certain high-risk AML or MDS to see if this approach can improve control of the disease while tracking safety.
