(Reuters) - AstraZeneca (NASDAQ:AZN) said its antibody-based cocktail to prevent and treat COVID-19 was shown to retain neutralising activity against Omicron coronavirus variants, including the highly contagious BA.2 sub-variant, in an independent lab study.

Data from the study by the Washington University showed the therapy reduced the amount of virus detected in samples of all tested Omicron subvariants in mice lungs, the London-listed drugmaker said on Monday. The study has yet to be peer reviewed.

The therapy, Evusheld, was tested against the BA.1, BA.1.1, and BA.2 subvariants of Omicron and it was also shown to limit inflammation in the lungs.

"The findings further support Evusheld as a potential important option to help protect vulnerable patients such as the immunocompromised who could face poor outcomes if they were to become infected with COVID-19," senior AstraZeneca executive John Perez said.

The World Health Organization said last week figures showing a global rise in COVID-19 cases could herald a much bigger problem, as the Omicron and BA.2 variants spread amid the easing of restrictions and testing.
