Brii Bio's cocktail therapy shows protection against Omicron BA.2

Brii Biosciences said its long-acting COVID-19 neutralizing antibody therapy retains neutralizing activity against the Omicron BA.2 SARS-CoV-2 subvariant.

Data showed that exposures of intravenous amubarvimab 1000mg and romlusevimab 1000mg are expected to remain above the level required for neutralizing activity against BA.2, for the treatment of COVID-19 based on the human pharmacokinetic data gathered on the amubarvimab/romlusevimab combination.

The company added that total serum concentrations of the amubarvimab/romlusevimab combination will remain 60 times the level required for greater than 90% neutralization (Neut99: 2.50 μg/mL) against the live virus isolate BA.2, 14 days post dose.

Even though the mutations found in the BA.2 subvariant spike protein increase the IC50 relative to wild-type SARS-CoV-2, Brii said adequate therapeutic exposures are expected to persist for a minimum of 2 weeks and longer.

Our combination therapy is one of the few treatments that is proven to retain neutralizing activity against Omicron BA.2 and all previous variants of concern as a result of its unique combination strategy, said David Margolis, Vice President and Head of Infectious Diseases Therapy Area at Brii Bio.
