Narrative Opinion Summary
The case involves a dispute between two pharmaceutical companies, A.L. Pharma, Inc. and Philips Roxane, Inc., over the FDA's approval of a new animal drug aimed at improving growth and feed efficiency in broiler chickens. Philips Roxane secured FDA approval based on bioequivalency data, which A.L. Pharma contested, alleging that the approval was unlawful. A.L. Pharma also challenged the ownership of the safety data used in the application, which the FDA dismissed. The district court initially granted summary judgment for the FDA, affirming the agency's acceptance of bioequivalency data and the substitution of safety data. A.L. Pharma appealed, leading to a partial affirmation and partial reversal by the appellate court, which remanded the case, requiring the FDA to provide a more detailed justification for its bioequivalency determination. The court highlighted the need for the FDA to clarify its standards for demonstrating bioequivalency in animal drugs. The case underscores the deference courts generally grant to agency expertise while ensuring agency decisions comply with the Administrative Procedure Act. The FDA must deliver a satisfactory explanation within 90 days, or the approval may be vacated.

Application: The FDA accepted bioequivalency data as proof of efficacy, which A.L. Pharma challenged, arguing the Prescott Study was insufficient.
Reasoning: The FDA's rationale for accepting bioequivalency proof over efficacy proof was based on its determination that Philips Roxane's bacitracin zinc was 'identical' to the benchmark drug.
