Adintrevimab (ADG 20) is a human IgG1 monoclonal SARS-CoV (SARS-CoV) antibody. Adintrevimab inhibits SARS-CoV-2 variants and other SARS-like coronaviruses with pandemic potential[1].
The crystallizable fragment (Fc) region of Adintrevimab has a modification to extend its half-life. Adintrevimab binds to a distinct epitope in the receptor-binding domain of the spike glycoprotein of SARS-CoV-2 that partially overlaps the angiotensin-converting enzyme 2 binding site and is highly conserved among sarbecoviruses. In vitro, Adintrevimab has demonstrated potent neutralizing activity against most variants and sublineages of SARS-CoV-2 (including Alpha, Beta, Gamma, and Delta) as well as other SARS-like viruses. Adintrevimab displays reduced in vitro activity against Omicron BA.1/BA.1.1 and lacks activity against BA.2, BA.3, BA.4, and BA.5[1].
Adintrevimab (9.25, 55, 333, or 2,000 μg; i.p.; once) provids protection against SARS-CoV-2/WA1/2020 infection in a dose-dependent manner[1].
Adintrevimab (5-25 mg/kg; i.v.; once) provids protection against SARS-CoV-2/WA1/2020 infection in a dose-dependent manner[1].
