Care plan for sickle cell pain crises in the ER
This trial studies an approach to improve care during emergency room visits for uncomplicated sickle cell pain crises. It may help by guiding how pain is treated in the ER and tracking outcomes for people with sickle cell disease.
Milwaukee, WisconsinAges Up to 18 years - NCT05933967RecruitingPhase 2
Orelabrutinib with R-CHOP for newly diagnosed lymphoma
This Phase 2 trial tests whether adding orelabrutinib to standard chemotherapy (R-CHOP) can improve treatment for people with newly diagnosed double-expressing diffuse large B-cell lymphoma. It’s intended for adults who are well enough to receive treatment and whose lymphoma is in the body (not in the brain/spinal fluid).
Nanchang, JiangxiAges 18–70 - NCT05996367Recruiting
Single radiation dose for painful myeloma bone lesions
This trial is testing whether a single dose of radiation can effectively relieve bone pain caused by multiple myeloma. It is designed for people who have a painful bone lesion and are stable on or off treatment.
São Paulo, São PauloAges 18–85 - NCT06005246Recruiting
Munich ME/CFS Study for Young People
This study is tracking children, teens, and young adults (up to age 25) who developed ME/CFS after an infection. It aims to better understand the condition in younger people.
Munich, BavariaAges Up to 25 years - 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 - NCT02934477Recruiting
Transplant study for higher-risk myelofibrosis patients
This trial studies whether an allogeneic (donor) stem cell transplant can help people with higher-risk myelofibrosis (fibrosis in the bone marrow). It looks at outcomes in different donor types as determined by matching rules and patient risk level.
Minneapolis, MinnesotaAges 55 years+ - NCT03127761Recruiting
Transplant study for Medicare patients with advanced myeloma
This study looks at outcomes of an allogeneic transplant (a donor-based transplant) in people with stage II–III multiple myeloma or primary plasma cell leukemia who have Medicare. It may help doctors better understand which patients benefit and what to expect before and after transplant.
Minneapolis, MinnesotaAges Any age - NCT05936086Recruiting
Testing high-dose cyclophosphamide to treat adult HLH
This trial studies whether giving high-dose cyclophosphamide as an initial treatment works better for adults with HLH. HLH is a serious, overactive immune condition, and the study aims to improve control of the illness and safety.
ChongqingAges 18–65 - NCT04463316Recruiting
Clinic study for people with rare genetic conditions
This study is for people who have a rare syndrome or rare congenital condition and are seen at a rare-disease clinic. It aims to better understand these conditions and how care works in a team setting, which may help guide future treatment decisions.
