IC50 & Target
influenza A virus hemagglutinin HA
In Vitro
Lesofavumab (MHAB5553A) binds to a conserved epitope in the vestigial esterase domain of hemagglutinin (HA), a major immunodominant surface glycoprotein on influenza B viruses, and blocks HA-mediated membrane fusion in the endosome[1].
Lesofavumab (46B8) is able to neutralize all eleven IBV strains tested that were associated with human infections spanning >70 years, with IC50 values ranging from 0.58 to 0.95 nM[2].
Lesofavumab (46B8; 0-100 ng/mL) blocks membrane fusion and induces antibody-dependent cellular cytotoxicity (ADCC) in vitro[2].

Animal Model:DBA/2 J mice, B/Wisconsin/1/2010, B/Brisbane/60/2008, B/Victoria/504/2000, B/Russia/1/1969 or B/Massachusetts/3/1966 infection model[2]
-
Dosage:15 mg/kg
-
Administration:Intravenous administration, single dose, 24, 48 or 72 h post infection
-
Result:Treatment at 24 and 48 h post infection resulted in 100% protection, with the only exception of mice infected with B/Russia/1/1969 that showed a 60% protection when treatment commenced at 48 h. Even when given at 72 h post infection, 48B8 was highly efficacious resulting in 100% protection against the B/Brisbane/60/2008, B/Victoria/504/2000 and B/Massachusetts/3/1966 strains, 75% protection against B/Wisconsin/1/2010 and 50% protection against B/Russia/1/1969.
