CD33KO-HSPC Infusion Followed by CART-33 Infusion(s) for Refractory/Relapsed AML
Phase 1 Study of Lentivirally Transduced T Cells Engineered to Contain Anti-CD33 Linked to TCRζ And 4-1BB Signaling Domains In Combination With CD33KO-HSPC In Subjects With Refractory Or Relapsed Acute Myeloid Leukemia

Summary
The purpose of this study is to provide a new type of treatment for AML. This treatment combines a new type of stem cell transplant along with treatment using chimeric antigen receptor (CAR) T cells that have been engineered to recognize and attack your AML cells. The first treatment is a modified stem cell transplant, using blood-forming stem cells donated from a healthy donor. From the same donor, we will also make CAR T-cells, which are leukemia fighting cells, which will be given to the patient via an infusion into the vein after the transplanted stem cells have started to grow healthy blood cells. The modification of the stem cell transplant means that the healthy bone marrow cells will be "invisible" to the CAR T-cells that are trying to kill the leukemia cells.

Interventions
CD33KO-HSPC: Stem cell transplant (also known as bone marrow transplant) is a common treatment used for patients with blood cancers, but for this transplant we will first modify the cells, in order to make the CAR T-cell treatment safer for when the patient receives them later. The modification is a type of gene editing - this means changing the DNA of the cells, so that a protein that the bone marrow stem cells usually show on their surface is not shown any more. This makes the bone marrow cells "invisible" to the CAR T-cells, and makes this therapy safer for the patient. The protein is called CD33. CART33: Chimeric Antigen Receptor T-cells (CART) are immune cells which are modified by adding a CAR molecule, which makes them much more efficient at finding and killing cancer cells. In this case, the CAR T-cells are programmed to target a protein called CD33, which is found on the surface of leukemia cells, and on healthy bone marrow cells.
