Office of New Animal Drug Evaluation

The Office of New Animal Drug Evaluation's (ONADE's) major responsibility is to review information submitted by drug sponsors who want approval to manufacture and market animal drugs. New animal drugs cannot be legally marketed unless they have been reviewed and approved, conditionally approved, or index-listed by FDA.

ONADE determines whether or not an animal drug should be approved for marketing. In order to approve and sustain a new animal drug for commercial use, four critical pillars must be met. First, an animal drug product must be safe, safe for the animal, safe for the humans consuming food derived from treated animals, safe for the user or the person administering the drug and for the environment. Second, an animal drug must be effective for its intended uses. These uses are those prescribed, recommended or suggested in the labeling of the product. Third, the animal drug must be a quality manufactured product, being the result of a validated manufacturing process conducted in accordance with current Good Manufacturing Practice regulations. Fourth, the product must be properly labeled to inform the user of the product not only how to use the product but also safety considerations, residue withdrawal procedures, and storage and handling procedures. When these four characteristics are met, an animal drug can be approved for marketing. Once in the market place, an animal drug is monitored to ensure that these characteristics are sustained. It is the responsibility of the drug sponsor (the individual or firm seeking FDA approval of the drug product) to conduct the necessary tests.

ONADE is divided into seven divisions, each charged with the evaluation of different aspects of a New Animal Drug Application (NADA). Effectiveness and target animal safety information is the responsibility of two divisions which evaluate drugs for therapeutic use (food animals and non-food animals), one division which evaluates production drugs and one division which evaluates generic animal drugs. The division of human food safety evaluates the safety to the public by ensuring edible products derived from food-producing animals treated with new animal drugs are safe for human consumption, The division of manufacturing technology evaluates the manufacturing processes and quality control while the division of scientific support evaluates environmental safety and provides statistical support to ONADE and the rest of the Center.

ONADE's project management team works with the seven divisions to coordinate review of the information submitted by drug sponsors. A determination is then made as to whether the information provided shows the product is safe and effective for its intended use. If the information shows the drug is safe and effective, a recommendation is provided to the Center Director that the NADA should be approved. If the Director agrees, he/she approves the application.

ONADE performs the following tasks in their review of applications:

  • Meets with sponsors in presubmission conferences to discuss development plans and reach agreement on the requirements for approval.
  • Reviews submitted protocols for experimental work conducted to provide the necessary information needed for the approval of the NADA.
  • Determines the adequacy of information submitted to support approval.
  • Evaluates the safety and effectiveness of new animal drug products.
  • Evaluates the safety for human consumption of drug residues in food derived from treated animals.
  • Evaluates the impact of animal drugs on the environment.
  • Evaluates manufacturing methods and procedures for new animal drug products.
  • Reviews the product labeling to ensure it is accurate and not misleading.
  • Prepares a Freedom of Information (FOI) summary of the information the agency relied upon to support approval.
  • Coordinates the development and implementation of regulations and policies pertaining to new drugs intended for animal use.
