SAB-185 is currently being evaluated in NIH-sponsored Phase 2/3 adaptive trial
SAB Biotherapeutics (SAB), a clinical-stage biopharmaceutical company with a novel immunotherapy platform that produces specifically targeted, high-potency, fully-human polyclonal antibody therapeutics without the need for human donors, announced the publication of data showing that SAB-185, the company’s therapeutic candidate for the treatment of COVID-19 infections, demonstrates effective and potent neutralization of multiple SARS-CoV-2 variants of concern, including the Delta and Lambda variants.
The nonclinical study was conducted by scientists at the US Food and Drug Administration (FDA) Center for Biologics Evaluation and Research (CBER) and published in bioRxiv, the online life sciences archive for COVID-19 SARS-CoV-2 preprints.
SAB-185 is a fully human, specifically targeted and broadly neutralizing polyclonal antibody therapeutic candidate. It is currently being assessed in a Phase 2/3 trial in non-hospitalized patients with mild-moderate COVID-19 infections. It is the first polyclonal antibody therapeutic included in the ACTIV-2 master protocol, a study sponsored, funded, and conducted by the National Institute of Allergy and Infectious Diseases (NIAID), part of the US National Institutes of Health (NIH).
“These encouraging data come at a critical time, as the Delta variant is causing a surge of COVID-19 infections around the globe and public health experts are voicing concerns about emerging new variants such as Lambda and others yet to be identified,” said Eddie J. Sullivan, PhD, co-founder, president and CEO of SAB Biotherapeutics. “These in vitro data demonstrating the efficacy of SAB-185 against the Delta and Lambda variants were produced to provide new insights into antibody binding to the SARS-CoV-2 spike variants, and as a result further bolster our confidence that SAB-185 has the potential to provide neutralization of current and future mutant SARS-CoV-2 strains. We look forward to working with our US government collaborators to advance our COVID-19 program, to make SAB-185 available to patients as soon as possible once its clinical utility is confirmed.”
