The US Food and Drug Administration (FDA) has recently made updates to forms 365h and 1571. Form 365h is “Application to Market a New or Abbreviated New Drug or Biologic for Human Use”. These applications are commonly referred to as NDA, ANDA or BLA. Form 1571 is “Investigational New Drug Application (IND)”. These are among the most important eCTD forms involved in your drug or biologic application process.
