After achieving billions in sales, the World Health Organization is no longer recommending two antibody treatments for Covid-19, on the grounds that they are likely no longer effective due to the Omicron strain of Corona Virus and its most recent sub-moderations. According to Archyde.com, according to experts in the United Nations.
Both treatments are designed to work by binding to the SARS-CoV-2 skeletal protein to neutralize the virus’s ability to infect cells, among the first drugs developed early in the pandemic.
Limited event
But the virus has since evolved, and mounting evidence from lab tests indicates that the efficacy of the two treatments, sutrovimab and cerifimab-imdivimab, is limited in the face of the latest mutations in the virus.
As a result, the US health regulator also excluded them.
And the World Health Organization experts said, on Thursday, that they strongly advised not to use them to treat people with Covid-19, reversing previous conditional recommendations, as part of a set of new recommendations published by the British Medical Journal.
Billions of sales
The US Food and Drug Administration pulled sotrofimab, which is produced by GlaxoSmithKline and its partner Ver Biotechnology, from the local market in April. The drug achieved billions in sales and became one of the best-selling drugs produced by British companies last year.
The antibody combination cacerifimab-imdivimab, produced by Regeneron and its partner Roche, also generated billions in sales and was one of the best-selling US drugs last year.
No efficacy in front of Omicron
The FDA revised its position on the treatment in January and limited its use to a smaller group of patients, citing its diminishing potency once morest the Omicron variant.
Despite this, the European Medicines Regulatory Authority still recommends the use of both treatments.
