Biosimilars continue to pose cheaper alternatives to their established, blockbuster counterparts.

The COVID-19 pandemic might be officially over, but future variants could still pose a threat, and serious health consequences of the causative virus continue to arise, a fact that has prompted the U.S. government to offer Regeneron Pharmaceuticals Inc. about $326 million to develop and manufacture a next-generation COVID-19 monoclonal antibody therapy.
