Testing blood samples to study multiple myeloma
This study looks at stored blood (serum) samples to see whether a lab test called MALDI-TOF mass spectrometry can help analyze multiple myeloma proteins. If you have multiple myeloma (or are a healthy matched control), your existing lab samples may be used for testing.

Studying biologic features in adults with newly diagnosed ITP
This study looks at blood and immune system patterns in adults with primary immune thrombocytopenia (ITP) who are starting their first treatment. The goal is to better understand what’s happening in ITP, which may improve how future patients are cared for.

This Phase 2 study tests a study treatment in adults with multiple myeloma that needs treatment. It may help by trying to improve disease control after you’ve had (or are scheduled to have) standard therapy like chemotherapy and stem cell transplant for some people.
BerlinAges 18–70 - NCT05695924Recruiting
Surgery to reduce arm swelling after breast cancer
This trial studies whether a specific surgery (a lymph vessel transplant) can reduce upper-arm lymphedema in people who developed swelling after breast cancer treatment. You must already have tried standard therapy and still have persistent, mild-to-moderate swelling.
Stanford, CaliforniaAges 18–75 - NCT05695638Recruiting
Genetic tumor testing to find treatments for advanced cancer
This study looks at your tumor’s genetic information to help match you to targeted treatments when standard options are no longer working. You may be offered options based on results, with the goal of helping people with incurable, worsening cancer.
AalborgAges 18 years+ - NCT05700149Recruiting
Study tests tumor testing to predict nodal marginal zone lymphoma
This study collects and analyzes tumor samples from people with nodal marginal zone lymphoma to better understand the disease and predict outcomes. It may help doctors characterize the lymphoma more accurately using clinical and lab information.
Miami, FloridaAges 18 years+ - NCT05702502Recruiting
Testing a DNA marker in lymphoma-related HLH
This trial looks for a DNA marker in people with HLH caused by lymphoma. It may help doctors better confirm the cause of HLH and guide treatment decisions.
Nottingham, NottinghamshireAges 18 years+ - NCT05702853RecruitingPhase 1/Phase 2
CAR T-cell therapy after CD34 selection for CD19 lymphoma or CLL
This Phase 1/2 study tests a customized type of immune cell treatment (CD19 CAR T-cells) for people with certain relapsed or hard-to-treat lymphomas or CLL/SLL. It aims to improve control of disease by targeting the CD19 marker on cancer cells.
Charleston, South CarolinaAges 18 years+ - NCT05703126Recruiting
Blood vessel and heart strength tests in AML patients
This study looks at how well your blood vessels and heart pumping ability work in people with acute myeloid leukemia (AML) receiving certain chemotherapy. It may help doctors better understand heart risk during treatment and tailor monitoring to you.
Samara, Samara OblastAges 18–65 - NCT05703542RecruitingPhase 1
Testing BXCL701 for relapsed or resistant AML or MDS
This Phase 1 study tests BXCL701 in adults whose acute myeloid leukemia (AML) or high-blast myelodysplastic syndrome (MDS-EB-2) has come back or not responded to prior treatment. The goal is to find a safe dose and see how the treatment affects cancer cells.
Boston, MassachusettsAges 18 years+ - NCT05705570RecruitingPhase 1
CAR-T for CD19-positive relapsed or resistant blood cancers
This trial tests a type of immune treatment (CAR-T cells) for blood cancers that have come back or did not respond after standard treatments. It is for tumors that have CD19 on their cells, aiming to reduce the cancer and improve remission chances.
São Paulo, São PauloAges 2–70 - NCT05706766Recruiting
Exercise coaching before stem cell transplant for multiple myeloma
This trial studies whether a structured exercise program before an autologous (your own cells) stem cell transplant can improve health and fitness in people with multiple myeloma. The goal is to safely prepare your body for transplant, and the study includes fitness testing and ongoing exercise training.
Boston, MassachusettsAges 18 years+ - NCT05707325RecruitingEarly Phase 1
Testing a lab-made red blood cell treatment for advanced cancers
This early trial studies whether an engineered (lab-made) red blood cell treatment is safe and tolerable, and whether it may show early anti-cancer activity. It may help people with advanced cancers whose disease has not responded well to standard options.
Hangzhou, ZhejiangAges 18–75 - NCT05708716Recruiting
