Guidance to Industry Preparing Supporting Summaries for Single Tier Effectiveness Statements

As part of a movement in 2015 toward single-tier effectiveness statements, 9CFR 112.5(b) was amended to require publication of efficacy and safety study summaries on the APHIS website productdata.aphis.usda.gov. This webpage provides details to licensees, permittees, and applicants on preparing and submitting information for those summaries.

A summary of a single study is known herein as an Individual Study Summary (ISS). It is prepared by the licensee and reviewed/edited/cleared by the Center for Veterinary Biologics (CVB) for standard content and appearance. All of the ISSs applicable to a single biological product are then compiled into a Product Compilation Summary (PCS), which is posted to productdata.aphis.usda.gov. The compilation is performed by the CVB.

Scope of Products Affected by Single-Tier

  • Vaccines, bacterins, toxoids, and immunomodulators are included under the scope of the new rule.
  • Products exempted include: antibody products, diagnostic test kits, autogenous or prescription products, and allergenic extracts.
