Design and evaluation of bi- and trispecific antibodies targeting multiple filovirus glycoproteins.

ABSTRACT: Filoviruses (family Filoviridae) include five ebolaviruses and Marburg virus. These pathogens cause a rapidly progressing and severe viral disease with high mortality rates (generally 30-90%). Outbreaks of filovirus disease are sporadic and, until recently, were limited to less than 500 cases. However, the 2013-2016 epidemic in western Africa, caused by Ebola virus (EBOV), illustrated the potential of filovirus outbreaks to escalate to a much larger scale (over 28,000 suspected cases). mAbs against the envelope glycoprotein represent a promising therapeutic platform for managing filovirus infections. However, mAbs that exhibit neutralization or protective properties against multiple filoviruses are rare. Here we examined a panel of engineered bi- and trispecific antibodies, in which variab
