Under the terms of the EUA, tocilizumab may only be infused in the hospital setting, in limited clinical situations. The emergence of the new pathogen SARS-CoV-2 determined a rapid need for monoclonal antibodies (mAbs) to detect the virus in biological fluids as a rapid tool to identify infected individuals to be treated or quarantined. Rather than binding with the ACE2 receptor-binding domain, the novel class 4 monoclonal antibodies target a site that is distant from the ACE2 binding domain yet can effectively neutralize multiple variants of concern, including Omicron variants. Both companies have in place large-scale manufacturing with robust, global supply chains in place to produce the monoclonal antibodies, with many global manufacturing sites to ramp up supply. The numbers around malaria are staggering. The antibodies themselves weren't made of any of these fetal cells, Kriegstein noted.
