Late-stage trials of the drug show it is 77% effective in reducing the risk of Covid-19 symptoms if administered as a preventive treatment.
AstraZeneca on Tuesday said it has requested an emergency use authorization grant from the U.S. Food and Drug Administration for its Covid-19 prophylaxis drug, a move that comes over a month after the antibody cocktail was shown to be effective in preventing symptoms among high-risk individuals who received the drug prior to exposure.
Unlike a vaccine which helps a recipient’s immune system build its own antibodies and infection-fighting cells against the virus, antibody treatments directly use lab-made antibodies that can linger in a person for months and protect them against infection. The company also noted that trials performed ‘in Vitro’ showed that the drug was able to neutralize emergent Covid variants, including delta and mu.
The drugmaker added that supply agreements for AZD7442 are ongoing with the United States and other governments around the world.
