COVID-19 involves the interplay of 350+ viral and host proteins and factors providing many therapeutic targets. Scientists have proposed 10,000+ potential treatments. c19early.org analyzes 210+ treatments. We have not reviewed FBR-002 in detail.
Luczkowiak et al., Potent Neutralizing Activity of Polyclonal Equine Antibodies against SARS-CoV-2 Variants of Concern, The Journal of Infectious Diseases, doi:10.1093/infdis/jiac331
Abstract Several monoclonal anti-SARS-CoV-2 antibodies (mAbs) have received emergency authorization for COVID-19 treatment. However, most of these mAbs are not active against the highly mutated Omicron SARS-CoV-2 subvariants. We have tested a polyclonal approach of equine anti-SARS-CoV-2 F(ab’)2 antibodies that achieved a high level of neutralizing potency against all SARS-CoV-2 VoCs tested including Omicron BA.1, BA.2, BA.2.12 and BA.4/5. A repertoire of antibodies targeting conserved epitopes in different regions of the spike protein could plausibly account for this remarkable breadth of neutralization. These results warrant the clinical investigation of equine polyclonal F(ab’)2 antibodies as a novel therapeutic strategy against COVID-19
