The Patient Protection and Affordable Care Act (PPACA), signed into law by President Obama on March 23, 2010, amends the Public Health Service Act (PHS Act) to create an abbreviated licensure pathway for biologic products that are demonstrated to be “biosimilar” to or “interchangeable” with an FDA-licensed biologic product. This pathway is provided in the part of the law known as the Biologics Price Competition and Innovation Act (BPCI Act).
