NCIt definition : A designed ankyrin repeat proteins (DARPin)-based, tri-specific agent composed of
three severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) spike protein (SP)
receptor-binding domain (RBD) binding domains that bind to the same epitope region
on the SARS-CoV-2 SP RBD and a human serum albumin (HSA)-binding domain, that can
potentially be used for immunization against COVID-19. Upon administration, ensovibep
specifically targets and binds to three epitopes in the same SARS-CoV-2 SP RBD region,
thereby blocking viral attachment and entry into human cells and may thereby neutralize
SARS-CoV-2. This may slow the progression of the disease and accelerate recovery,
and may potentially provide temporary protection against infection with SARS-CoV-2.
Binding to three epitopes of the SARS-CoV-2 SP RBD may decrease the potential for
viral escape through mutations. The HSA-binding domain binds to HSA which prolongs
the half-life of the agent.;
