Increase NADH and NAD redox potential and decrease endothelial adhesion. Simvastatin was found to reduce adhesion of white blood cells and in combination with hydroxyurea, was found to decrease the number of pain crisis and markers of inflammation (Hoppe et al., 2017). A phase 3 study (Identifier: NCT02187003) to evaluate the efficacy and safety of rivipansel in the treatment of VOC in hospitalized patients with SCD was terminated (posted on February 20, 2020) based on failure of the primary study (NCT02433158) to meet the study efficacy endpoints of time to readiness-for-discharge.

HbAS refers to heterozygotes or carriers of the HbS mutation: these individuals have HbS of 30%–40% and are asymptomatic. A phase 2 study (NCT01077921) showed decrease in adhesion molecules such as E-selectin and P-selectin but results were not statistically significant and no clinical endpoints were discussed (De Castro et al., 2012). Natural regulatory mutations elevate the fetal globin gene via disruption of BCL11A or ZBTB7A binding.
