New Pacific Research Institute Brief: Regulatory Roadblocks Hinder Development of New COVID-19 Treatments for the Immunocompromised

Monoclonal antibodies, or mAbs, work by mimicking the body's natural antibodies, which is why they are so valuable to treating the immunocompromised. Six different mAbs were authorized by the federal Food and Drug Administration (FDA) early on during the COVID-19 pandemic. However, the predominant COVID-19 strain -- the JN.1 variant -- shows numerous mutations all at once. As a result, the FDA has pulled authorization for current treatments as the current virus continues to mutate.
