Testing two antibody drugs for lymphoma that came back
This Phase 2 trial tests two targeted antibody medicines—loncastuximab tesirine and mosunetuzumab—in people whose diffuse large B-cell lymphoma (DLBCL) or follicular lymphoma grade 3B has come back or did not respond. It aims to shrink lymphoma that has measurable disease and has specific markers (CD19 and CD20) on tumor cells.
Duarte, CaliforniaAges 18 years+ - NCT05602363RecruitingPhase 1
Docirbrutinib for CLL or lymphoma after prior treatments
This Phase 1 study tests docirbrutinib, a targeted pill treatment, in people with CLL/SLL or certain other B-cell lymphomas that have come back or didn’t respond to earlier therapy. The goal is to see whether it’s safe and whether it can control the disease after standard treatments have failed.
Orange, CaliforniaAges 18 years+ - NCT05418088RecruitingPhase 1
CAR T-cell therapy for hard-to-treat B-cell cancers
This Phase 1 study tests lab-made immune cells (CAR T-cells) that target CD19, CD20, and/or CD22 in people with certain relapsed or refractory B-cell cancers. It may help by attacking cancer cells that still carry these targets, but eligibility is very specific and includes prior treatments and health/lab requirements.
Columbus, OhioAges 2 years+ - NCT05366218RecruitingPhase 1/Phase 2
Tafasitamab for kids with high-risk B-cell leukemia after relapse
This Phase 1/2 study tests tafasitamab in children and teens with B-lineage acute lymphoblastic leukemia (ALL) that has come back or did not respond. It is mainly for patients with specific high-risk leukemia changes and/or leukemia markers that stay after stem cell transplant or CAR T-cell therapy.
Freiburg im Breisgau, Baden-WurttembergAges 3–18 - NCT05147467RecruitingPhase 2
Trial of APG-2575 for returning or resistant CLL/SLL
