Rio de Janeiro, Rio de JaneiroAges 30–50 - NCT04513639RecruitingPhase 2/Phase 3
Checking treatment for multiple myeloma after MRD becomes negative
This study looks at whether people with newly diagnosed multiple myeloma can safely continue or adjust treatment after they reach “MRD-negative,” meaning very low signs of disease in the bone marrow. It may help reduce the chance of relapse while avoiding unnecessary treatment for some patients.
ÅlesundAges 18–75 - NCT04513626RecruitingPhase 2
HIV trial testing doravirine plus raltegravir in adults
This Phase 2 trial studies whether switching to a combination of doravirine and raltegravir can safely maintain control of HIV in adults whose virus is already well suppressed. It may help people who are currently on stable HIV treatment and are not resistant to these specific medicines.
Paris, Île-de-France RegionAges 18 years+ - NCT04518475RecruitingPhase 4
Eltrombopag with rituximab versus eltrombopag alone for ITP
This trial compares two treatment approaches for adults with primary immune thrombocytopenia (ITP), a condition where platelet counts are too low. It looks at whether adding rituximab to eltrombopag helps control ITP better and more safely.
TianjinAges 18–60 - NCT04521790Recruiting
Biopsy-guided treatment for suspected inflammation of the heart
This study looks at people 18 and older with suspected myocarditis (inflammation of the heart). It uses an inner-heart biopsy and tailored treatment based on the likely cause to improve diagnosis and care, especially for people with different heart rhythm or non-rhythm symptoms.
Milan, MilanoAges 18 years+ - NCT04528355Recruiting
Study of hospital data after stem cell transplant for non-cancer illness
This study collects medical information from people with certain non-cancer conditions who receive a stem cell transplant. It may help doctors better understand transplant outcomes and care, since the study focuses on data collection rather than adding new treatment.
Pittsburgh, PennsylvaniaAges 2 months–60 years - NCT04532203RecruitingEarly Phase 1
CAR-T therapy for leukemia or lymphoma in the brain
This early-phase study tests CAR-T cells—immune cells engineered to recognize cancer—for people whose leukemia or lymphoma has spread to the central nervous system (the brain/spinal fluid). It may help shrink or control hard-to-treat (relapsed or refractory) cancers in the brain.
Hangzhou, ZhejiangAges 3–75 - NCT04532281RecruitingEarly Phase 1
CD19 CAR-T therapy for relapsed or resistant blood cancers
This early-phase study tests a treatment called CD19 CAR-T, made from your immune cells, for people whose CD19+ blood cancer has come back or did not respond. It may help your body better recognize and attack cancer cells, but eligibility is tight and the study is still early.
Hangzhou, ZhejiangAges Any age - NCT04532268RecruitingEarly Phase 1
CD19 CAR-T for relapsed or resistant B-cell blood cancers
This early-phase study tests “humanized” CD19 CAR-T therapy for people whose B-cell acute lymphoblastic leukemia (ALL) or B-cell lymphoma (NHL) has come back or didn’t respond. It’s designed to help the immune system recognize and attack cancer cells carrying the CD19 marker.
Hangzhou, ZhejiangAges 3–75 - NCT04533217Recruiting
