Daughters of Its... Omicron: Variant Mutations Render Antibody Drugs 'Useless'
Constant mutations of COVID-19 are making it increasingly difficult for manufacturers to keep up, leading to the ineffectiveness of the last two antibody drugs on the market.
Constant mutations of the COVID-19 virus have created a significant challenge for manufacturers of antibody treatments, rendering their products increasingly ineffective. The latest 'descendants' of the Omicron variant pose a serious threat to the final two antibody medications available: Eli Lilly's bebtelovimab, which is used to treat symptoms, and AstraZeneca's Evusheld, designed to prevent infections. As the virus evolves, previous antibody treatments have been withdrawn from the market due to their ineffectiveness against new strains.
Initially, during the onset of the pandemic, scientists rapidly developed antibody drugs to mitigate the worst effects of the virus by neutralizing it before it could cause serious harm. This approach was based on the understanding that a targeted antibody can promptly neutralize a threat within the body, halting the onset of infection. As new variants emerged with mutations that enabled the virus to evade these antibodies, many of the early treatments became obsolete, and the landscape of available therapeutic options has become dangerously sparse.
With the alarming pace of mutations and minimal progress in developing effective new antibody drugs, healthcare professionals may soon find themselves with limited or no treatment options for patients suffering from severe COVID-19 symptoms or at risk of infection. This ongoing evolution of the virus underscores the need for adaptive strategies in vaccine development and broader therapeutic interventions to manage and control the disease effectively.
