Study on T-cell cancers after tisagenlecleucel treatment
This study looks at people who developed a new T-cell cancer after receiving the CAR-T therapy tisagenlecleucel (Kymriah). Researchers want to understand these rare cancers by testing stored tumor samples. You may be eligible if you had tisagenlecleucel and were later diagnosed with a T-cell malignancy.

Study of calf vein clots with ultrasound monitoring
This study follows people with a blood clot in the calf vein to learn how the clot changes over time using repeat ultrasound scans. It may help doctors understand who needs treatment and who can be watched safely.
Dresden, SaxonyAges 18 years+ - NCT07530380RecruitingEarly Phase 1
CAR T-cell therapy for treatment-resistant autoimmune hemolytic anemia
This trial tests a new type of cell therapy called UCAR T-cells, which are immune cells engineered to target and destroy the B cells causing your body to attack its own red blood cells. It's designed for patients whose autoimmune hemolytic anemia hasn't responded to at least 3 standard treatments.
HefeiAges 10 years+ - NCT06757855RecruitingPhase 1/Phase 2
A study of three drugs for advanced CML
This trial tests a combination of three drugs (olverembatinib, venetoclax, and azacitidine) for people with a fast-growing form of chronic myeloid leukemia (CML) called blast phase. The goal is to see if this treatment can help control the leukemia when it has moved to a more aggressive stage.
Tianjin, Tianjin MunicipalityAges 15 years+ - NCT07053605Recruiting
Laparoscopic splenic artery aneurysm repair, spleen saved
This study tests a keyhole surgery (laparoscopy) to remove an aneurysm from the splenic artery while saving your spleen. It may help people with larger, growing, or ruptured splenic artery aneurysms.
Yangzhou, JiangsuAges 18 years+ - NCT07237230Recruiting
Gamma-delta T cells to prevent leukemia relapse after transplant
This trial tests if a special type of immune cell called gamma-delta T cells can help prevent acute myeloid leukemia from coming back after a stem cell transplant. It is for people with high-risk features who have recently had a transplant.
