CPAP or BiPAP to reduce motion during radiation
This study tests whether using a breathing machine (CPAP or BiPAP) can help keep you still during radiation treatment. This may improve how accurately radiation is delivered for certain cancers treated with curative intent.
Groningen, Provincie GroningenAges 18 years+ - NCT02161783Recruiting
Second transplant for blood stem cell graft failure
This trial studies treatment after a first stem cell transplant fails to produce lasting blood recovery. It may help people who need a second transplant because their counts never fully recovered or then dropped again.
Minneapolis, MinnesotaAges Any age - NCT02442011Recruiting
Blood disorder biosample study
This trial collects and studies blood samples from people with blood disorders. It may help researchers better understand blood conditions using lab testing rather than a new medication.
The Bronx, New YorkAges 12 years+ - NCT04870944RecruitingPhase 1/Phase 2
CBL0137 for children with advanced solid or brain tumors
This early-phase study tests CBL0137 in children and teens whose cancer has come back or is not responding to treatment. It is also for some specific hard-to-treat brain tumors, to see if the drug is safe and can work against the cancer.
Birmingham, AlabamaAges 1–21 - NCT04895436RecruitingPhase 2
Oral venetoclax plus IV obinutuzumab after prior CLL treatment
This trial tests whether adding oral venetoclax together with an IV antibody called obinutuzumab can control CLL when the disease comes back after a specific prior treatment. It also looks closely at side effects to see what changes in “disease activity” and safety to expect.
La Jolla, CaliforniaAges 18 years+ - NCT04910568RecruitingPhase 1
Study of cevostamab for people with returning or hard-to-treat myeloma
This trial tests a new drug called cevostamab for people whose multiple myeloma has come back or stopped responding to treatment. It aims to see if the drug is safe and how well it works.
Duarte, CaliforniaAges 18 years+ - NCT04877522RecruitingPhase 4
Continued asciminib treatment for certain leukemia patients
This trial lets people who already have Philadelphia chromosome–positive (Ph+) leukemia and are benefiting from asciminib (or certain related medicines) continue treatment. It mainly tests whether ongoing care in a follow-on study is safe and workable for participants.
Ann Arbor, MichiganAges 7–100 - NCT04925479RecruitingPhase 1/Phase 2
Testing asciminib dosing and safety for teen CML patients
This early-phase study tests the right dose and safety of asciminib in children and teens with chronic myeloid leukemia (CML). It may help if your current or last CML medicine (a TKI) did not work well or caused side effects.
Indianapolis, IndianaAges 1–17 - 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 - NCT04901936RecruitingPhase 2
Study of pegcetacoplan for kids with PNH blood problems
This trial tests pegcetacoplan in children (ages 12–17) with paroxysmal nocturnal hemoglobinuria (PNH), a condition that can cause ongoing blood cell breakdown. The goal is to see if the medicine can improve anemia related to PNH.
Atlanta, GeorgiaAges 12–17 - NCT04872478RecruitingPhase 1
Early-phase drug safety and dosing study for relapsed blood cancers
This Phase 1 trial tests MRX-2843 in teenagers and adults whose leukemia has come back or did not respond to prior treatment. The main goals are to find safe dosing and learn how the body processes the drug.
Atlanta, GeorgiaAges 12 years+ - NCT04879043RecruitingPhase 1/Phase 2
Safety study of HDP-101 for relapsed myeloma patients
This early-phase trial tests whether HDP-101 is safe and can potentially help adults with multiple myeloma that has come back or didn’t respond to standard treatments. It focuses on people who have already tried key myeloma medicines and still have measurable disease.
Atlanta, GeorgiaAges 18 years+ - NCT04872179Recruiting
Registry for people affected by alpha thalassemia
This is a research registry collecting information about people with alpha thalassemia to support ongoing studies. It may help the team better understand how fetal stem cell treatments are working and for whom they may be most suitable.
San Francisco, CaliforniaAges Any age - NCT04869683Recruiting
Collecting blood and tissue samples in myelodysplastic syndrome
This trial collects and stores biological samples (like blood or other lab materials) from people with myelodysplastic syndrome, to help researchers learn more about the disease. It may help future diagnosis or treatments, even if it doesn’t directly test a new medicine.
BrestAges 18 years+ - NCT04892277RecruitingPhase 1
CD19 CAR-T for adults with hard-to-treat B-cell cancers
This Phase 1 trial tests a lab-made immune therapy (CD19 CAR-T) for adults whose B-cell cancers have come back or did not respond to treatment. It may help your immune system better recognize and attack cancer cells, but it is early research, so benefits and risks are still being defined.
Rochester, MinnesotaAges 18 years+ - NCT04888338Recruiting
Studying outcomes after CAR-T, radiation, or bispecific therapy
This study looks at how people with blood cancers do after they receive CAR-T therapy, radiation therapy, and/or bispecific therapy. It may help doctors understand which treatment combinations work best and what side effects to expect.
Houston, TexasAges 18 years+ - NCT04861064RecruitingPhase 2
Weekly sirolimus for blood and lymph vessel malformations
This trial studies whether taking sirolimus once a week can improve blood vessel, lymph vessel, or mixed (venolymphatic) malformations. It may help reduce symptoms and lesion size, while also monitoring safety in children and adults.
Charleston, South CarolinaAges 2 years+ - NCT04904146Recruiting
Testing blood or tumor markers in skin lymphoma patients
This study looks for “predictive” and “prognostic” biomarkers—measurable signs in blood or tissue—to help predict how mycosis fungoides or Sézary syndrome will behave and how patients may respond to care. It may help doctors better understand outcomes for people with these skin lymphomas.
LundAges 18–100 - NCT04892823Recruiting
Study social support to see effects after a bone marrow transplant
This study looks at how social relationships and support may affect “accelerated aging” in people soon after a bone marrow (hematopoietic cell) transplant. It may help researchers understand what kinds of support could improve health and recovery after transplant.
Milwaukee, WisconsinAges 18 years+ - NCT04914091Recruiting
Study comfort and medication use after CAR-T therapy

Natural history study for lung scarring patients
This study follows people who are being seen for lung scarring (also called ILD) and compares them with family members without lung scarring. It helps researchers better understand how this condition changes over time and what to look for in the future.
Charlottesville, VirginiaAges 18 years+ - NCT04858256RecruitingPhase 2
Pacritinib for relapsed or resistant T-cell blood cancers
