Hematopoietic Stem Cell BCL11A Enhancer Gene Editing for Severe β-Hemoglobinopathies

A promising approach for the treatment of genetic diseases is called gene therapy. Gene therapy is a relatively new field of medicine that uses genetic material (mostly DNA) from the patient to treat his or her own disease. In gene therapy, the investigators introduce new genetic material in order to fix or replace a diseased gene, with the goal of curing the disease. The procedure is similar to a bone marrow transplant, in that the patient's malfunctioning blood stem cells are reduced or eliminated using chemotherapy, but it is different because instead of using a different person's (donor) blood stem cells for the transplant, the patient's own blood stem cells are given back after the new genetic material has been introduced into those cells. This approach has the advantage of eliminating any risk of Graft-Versus-Host Disease (GVHD), reducing the risk of graft rejection, and may also allow less chemotherapy to be utilized for the conditioning portion of the transplant procedure. The method used to fix or replace a diseased gene is called gene editing. A person's own cells are edited using a specialized biological medicine that has been formulated for use in human beings. Fetal hemoglobin (HbF) is a healthy, non-sickling kind of hemoglobin. Investigators have recently discovered a gene called BCL11A that is very important in the control of fetal hemoglobin expression. Increasing the expression of this gene in sickle cell patients could increase the amount of fetal hemoglobin while simultaneously reducing the amount of sickle hemoglobin in their blood, and therefore potentially cure the condition.

Hypoxic Red Blood Cells in Sickle Cell Anemia

The overall objective of this study is to evaluate the effectiveness and safety of transfusing hypoxic red blood cells manufactured with the Hemanext ONE system in patients with sickle cell anemia. The Hemanext ONE device was cleared through the De Novo process in September 2023.

Targeting the Pathophysiology of Sickle Cell-Related Kidney Disease Using the SGLT2 Inhibitors, Empagliflozin

Sickle cell anemia (SCA) is an inherited red blood disorder. The kidneys are among the most commonly affected organ systems in SCA. The Food and Drug Administration (FDA) has approved empagliflozin as a treatment to reduce the decline of kidney function in those with kidney disease. The proposed research study aims to determine whether empagliflozin can prevent the progression of kidney dysfunction in patients with sickle cell anemia (SCA) who are at high risk of developing advanced chronic kidney disease (CKD).
