Abstract:Fentanyl and other synthetic opioids are the leading cause of drug-related deaths in the United States. mAbs that selectively target fentanyl and fentanyl analogues offer a promising strategy for treating both opioid-related overdoses and opioid use disorders. To increase the duration of efficacy of a candidate mAb against fentanyl, we selected three sets of mutations in the Fc region of an IgG1 anti-fentanyl mAb (HY6-F9DF215, HY6-F9DHS, HY6-F9YTE) to increase binding to the neonatal Fc receptor (FcRn). The mA… Show more
