CD45BE-HSPC + CART-45 Cells

This is a phase 1, open-label, dose-finding study to assess the safety, feasibility, pharmacokinetics and preliminary efficacy of autologous base edited anti-CD45 CAR T cells (referred to as "CART-45 cells") following an autologous transplant of CD45 base edited hematopoietic stem and progenitor cells (referred to as "CD45BE-HSPC") in patients with relapsed or refractory hematologic malignancies.

CD5 CAR T-Cell Therapy for r/r T-cell Lymphomas

This is a multi-center, open-label, non-randomized, single-arm clinical trial. Refractory/relapse T-NHL patients are treated with autologous and allogeneic CD5 CAR T-cell therapy. The primary objective is to prospectively evaluate the safety of CD5 CAR T cell bridging to HSCT in the treatment of r/r T-NHL. The primary endpoint is the type and incidence of dose limiting toxicity (DLT) within 21 days after CD5 CAR-T cell infusion. A total of 36 subjects is estimated to be enrolled.

CD7 CAR T-Cell Therapy for r/r T-cell Lymphomas

This is a multi-center, open-label, non-randomized, single-arm clinical trial. Refractory/relapse T-NHL patients are treated with autologous and allogeneic CD7 CAR T-cell therapy. The primary objective is to prospectively evaluate the safety of CD7 CAR T cell bridging to HSCT in the treatment of r/r T-NHL. The primary endpoint is the type and incidence of dose limiting toxicity (DLT) within 21 days after CD7 CAR-T cell infusion. A total of 36 subjects is estimated to be enrolled.

Dose-Escalation and Dose-Expansion Study to Evaluate the Safety and Tolerability of Anti-CD7 Allogeneic CAR T-Cells (WU-CART-007) in Patients With CD7+ Hematologic Malignancies

Effective treatment options for relapsed/refractory acute myeloid leukemia (AML) and T-cell non-Hodgkin lymphoma (T-NHL) represent a significant unmet medical need. CAR T therapy has offered durable remissions and potential cures in some forms of hematologic malignancy, including B-cell acute lymphoblastic leukemia. In AML, however, CAR T approaches have been limited by the lack of suitable antigens, as most myeloid markers are shared with normal hematopoietic stem cells and targeting of these antigens by CAR T therapy leads to undesirable hematologic toxicity. Similarly, T-NHL has not yet benefited from CAR T therapy due to a lack of suitable markers. One potential therapeutic target is CD7, which is expressed normally on mature T-cells and NK-cells but is also aberrantly expressed on \~30% of acute myeloid leukemias. CAR T therapy for patients with CD7+ AML and T-NHL will potentially offer a new therapeutic option which has a chance of offering durable benefit. WU-CART-007 is a CD7-directed, genetically modified, allogeneic, fratricide-resistant chimeric antigen receptor (CAR) T-cell product for the treatment of CD7+ hematologic malignancies. These cells have two key changes from conventional, autologous CAR T-cells. First, because CD7 is present on normal T-cells including conventional CAR T products, CD7 is deleted from WU CART-007. This allows for targeting of CD7 without the risk of fratricide (killing of WU-CART-007 cells by other WU-CART-007 cells). Second, the T cell receptor alpha constant (TRAC) is also deleted. This makes WU CART 007 cells incapable of recognizing antigens other than CD7 and allows for the use of an allogeneic product without causing Graft-versus-Host-Disease (GvHD).
