Tixagevimab

Cat# : THA-0151

Product Datasheets COA :
Cat#:  THA-0151
Product Name:  Tixagevimab
Description:  Tixagevimab is an extended half-life recombinant monoclonal IgG1魏 antibody directed against the SARS-CoV-2 S protein for COVID-19 prophylaxis in individuals unable to undergo COVID-19 immunization.
Sequences:  Not Available
Molecular Weight:  149000.0 Da (approximate)
Introduction:  SARS-CoV-2, the causative agent of COVID-19, enters cells via the interaction between the trimeric spike (S) glycoprotein and host cell angiotensin-converting enzyme 2 (ACE2). Blocking the interaction between the receptor-binding domain (RBD) of the S1 subunit and ACE2 inhibits viral host cell entry; animal studies indicate that antibodies capable of blocking this interaction reduce viral load and improve clinical symptoms of infection. Tixagevimab (formerly AZD8895) is a recombinant monoclonal antibody produced in Chinese hamster ovary (CHO) cells derived from a neutralizing antibody isolated from a patient with a natural history of SARS-CoV-2 infection and modified through targeted amino acid substitutions to exhibit an extended (~85-day) half-life. As the RBD binding site of tixagevimab does not overlap with that of cilgavimab, the two can be administered to synergistically impair SARS-CoV-2 infection in individuals who may be exposed to the virus. Tixagevimab is not approved for any indication by the FDA. Tixagevimab, in combination with cilgavimab, was issued an FDA emergency use authorization (EUA) on December 9, 2021, for the pre-exposure prophylaxis of COVID-19 in individuals at increased risk for whom vaccination is not recommended. The combination is co-packaged and available under the name EVUSHELD (formerly AZD7442). EVUSHELD was granted marketing authorization by the EMA on March 28, 2022,5 and was approved in Canada soon after, on April 14, 2022. In October 2022, the FDA and Health Canada released safety alerts regarding the risk of developing COVID-19 when exposed to SARS-CoV-2 variants not neutralized by EVUSHELD. Certain SARS-CoV-2 Omicron subvariants may be associated with resistance to monoclonal antibodies, such as EVUSHELD. The FDA and Health Canada advise healthcare providers to inform patients of this risk.
