  • Observational Study Protocol Registration Template Available: The Observational Study Protocol Registration Template is intended to help investigators understand and gather the data needed to complete each registration module for an observational study. The template displays this information in a non-fillable Portable Document Format (PDF) file. (The template cannot be used to submit data directly to the Protocol Registration and Results System (PRS).) For a description of each data element, see the Protocol Registration Data Element Definitions.
  • Clarification Added to Voluntary Submission Flowchart and Triggered Trials Checklist: Clarifying text has been added to the Voluntary Submission Flowchart and Triggered Trials Checklist to indicate the flowchart should not be used for the purpose of evaluating whether a study is an applicable clinical trial. The flowchart is only intended to help responsible parties determine whether a specific study is a voluntary submission under Section 402(j)(4)(A) of the PHS Act and 42 CFR 11.60.
