| Description | The antibody S2K146 is a human mAb specific for SARS-CoV-2 Spike S1 protein. It broadly neutralizes viruses belonging to SARS-CoV- and SARS-CoV-2-related sarbecovirus clades, which use angiotensin-converting enzyme 2 (ACE2) as an entry receptor. It inhibited binding of the SARS-CoV-2 and SARS-CoV RBDs to human ACE2 in a concentration-dependent manner. It protects against SARS-CoV-2 Beta variant challenge in hamsters, and viral passaging experiments reveal a high barrier for emergence of escape mutants, making it a good candidate for clinical development. |
