Abstract
After decades with few treatment options for individuals with sickle cell disease (SCD), we have entered a treatment era of promising new therapeutic agents. These novel approaches target the diverse pathophysiology associated with SCD (e.g., increased blood cell adhesion, activated coagulation system, hyperinflammation, endothelial dysfunction). Potential therapies can be classified according to the “level” of the target intervention and related to the pathophysiology of SCD (upstream versus downstream events). In this chapter, “upstream therapies” refer to those that correct the genetic defect (correction of the sickle mutation in the beta globin gene via hematopoietic stem cell transplantation or gene therapy/gene editing), alter the natural hemoglobin switch phenomenon (enhancement of fetal hemoglobin production via gene therapy/gene editing), or prevent hemoglobin polymerization (e.g., drugs that alter the hemoglobin oxygen affinity or enhance fetal hemoglobin production). “Downstream therapies” are those aimed at quelling the downstream effects of hemolysis and vaso-occlusion (e.g., anti-adhesive, anti-inflammatory, or vaso-dilatory agents). This chapter discusses new therapies both in pre-clinical and clinical stages of investigation, and emphasizes those with the highest likelihood for impact on the disease and translation into clinical use over the next decade.
