Technical Sections and Final Study Reports For Submission to the
Division of Therapeutic Drugs for Non-Food Animals
This document is intended to provide guidance on the content and format of technical section submissions for effectiveness and target animal safety and final study reports in support of these technical sections. This guidance represents the Food and Drug Administration’s (FDA’s) current thinking on the content and format of effectiveness and safety technical sections and final study reports for submission solely to the Division of Therapeutic Drugs for Non-Food Animals. It does not create or confer any rights for or on any person and does not operate to bind FDA or the public. An alternative approach may be used if such approach satisfies the requirements of the applicable statute, regulations or both.
Comments and suggestions regarding this document should be submitted to Dockets Management Branch (HFA-305), Food and Drug Administration, 5630 Fishers Lane, Rm. 1061, Rockville, MD 20852.

I. Foreword
This guidance document was prepared to enable sponsors to submit “quality” data submissions, which will allow for a more efficient review by CVM. The scope of this document is limited to submissions to the Division of Therapeutic Drugs for Non-Food Animals (HFV-110).
A complete New Animal Drug Application (NADA) must be composed of all the sections identified in 21 CFR §514.1 and as stated on the Form FDA 356V. In order to facilitate the approval of NADAs, CVM now accepts major data submissions for individual sections of an NADA (technical sections) under the Investigational New Animal Drug (INAD) file. To the extent possible, CVM reviews each technical section independently. When CVM finds that all the sections are complete the sponsor may file an “administrative NADA”. This guidance document will focus exclusively on the effectiveness and the target animal safety technical sections reviewed by the Division of Therapeutic Drugs for Non-Food Animals.
In CVM’s efforts to find ways of improving its efficiency, it was discovered that reviewers often found it difficult to locate specific elements within a technical section and determine if all necessary elements of the technical section were present in the submission. This document addresses that problem and is intended to provide guidance on the suggested content and format of technical section submissions. Adherence to this guidance should assist CVM reviewers in locating and reviewing this information. The information contained in this guidance applies whether effectiveness and target animal safety data are submitted as individual technical sections under an INAD or collectively as part of a complete NADA. This document also provides guidance on the content and format of a final study report, which is a fundamental component of these technical sections.
Other relevant documents (where appropriate, Office of Management and Budget (OMB) information control numbers are in parentheses following the title of the document) include: 21 CFR Part 511 – New Animal Drugs for Investigational Use (OMB 0910-0017), 21 CFR Part 514 – New Animal Drug Applications (OMB 0910-0037), 21 CFR Part 58 – Good Laboratory Practice for Nonclinical Laboratory Studies (GLPs) (OMB 0910-0119), 21 CFR Part 11 – Electronic Records; Electronic Signatures (OMB 0910-0303), Good Target Animal Study Practices: Clinical Investigators and Monitors (May 1997), Target Animal Safety Guidelines for New Animal Drugs (June 1989), Protocol Development Guideline for Clinical Effectiveness and Target Animal Safety Trials (November 1994), and CVM’s Policy and Procedures Manual 1240.3040.

Administrative New Animal Drug Application: The NADA submission that is filed for the purpose of seeking approval of the new animal drug for the tested claims after CVM has issued technical section complete letters for all technical sections.
Adverse Drug Experience (ADE): Any adverse event associated with the use of an investigational or approved new animal drug, whether or not considered to be drug related.
Animal Drug Availability Act of 1996 (ADAA): Legislation enacted October 9, 1996, to amend the Federal Food Drug and Cosmetic Act. The purpose of the ADAA is to facilitate the approval and marketing of new animal drugs and medicated feeds. Among other items, the ADAA revised the definition of substantial evidence, which is the standard for demonstrating effectiveness.
Clinical Study: A single scientific experiment conducted to test at least one scientific hypothesis relevant to the proposed claim(s) made for a new animal drug.
Dosage: Dosage includes the dose or dose range, dosing frequency and dosing duration.
Experimental Phase Completion Date (for clinical studies): The date on which collection of all raw data is complete.
Experimental Phase Initiation Date (for clinical studies): The date on which animals are first identified with a treatment.
Final Study Report:
Good Laboratory Practices (GLPs): The regulations governing the conduct of nonclinical laboratory studies (21 CFR Part 58).
Investigator:
Monitor:
An individual qualified by training and experience who represents the sponsor in overseeing the investigator’s implementation of a protocol and progress of the clinical study and determines whether the clinical study is conducted in accordance with all applicable requirements.Nonclinical Laboratory Study:
In vivo or in vitro experiments in which test articles are studied prospectively in test systems under laboratory conditions to determine their safety. See §58.3 (d) for a more detailed definition.Protocol:
A document signed and dated by the investigator for clinical studies (or study director for GLP studies) and the sponsor, that states the rationale and objectives of the study and all methods and conditions under which the study is to be performed and managed. The term protocol includes all protocol amendments.

considered raw data.
Study Director: These records include, but are not limited to: Study Initiation Date: Study Completion Date: Substantial Evidence:
Technical Section:
An organizational element of an NADA as defined in §514.1 and outlined in the Form FDA 356V. Each technical section must support a condition of approval required by CVM. All studies supporting a single technical section should be submitted as well as other relevant information such as referenced literature, foreign market experience, etc. A technical section should also contain information on the proposed conditions of use and/or labeling, and the relevant portion(s) of the FOI Summary.III. Effectiveness
A. Content and format of the technical section
1. Cover letter
The content of the cover letter is administratively used to route the submission to the proper review personnel. Therefore, it is essential to make the purpose of the submission explicit in this letter. The following elements should be included in the cover letter:
INAD file number
Name, address, and telephone number of the sponsor
Drug name (include trade name and generic name)
Specific purpose of the submission
Proposed indications
The cover letter and supporting information should be mailed to: Center for Veterinary
Medicine, Document Control Unit, HFV-199, 7500 Standish Place, Rockville MD 20855.
A general table of contents for the technical section is recommended. Within a particular final study report or volume, a more detailed table of contents is also recommended.
Following the enactment of the ADAA, dosage justification and characterization of critical aspects of the dose-response relationship are no longer necessarily part of the determination of effectiveness by substantial evidence. Dosage justification and dose-response characterization may be supported by several means, including but not limited to, dose titration studies, pilot studies or literature (as opposed to dose confirmation). Confirmation of the effectiveness of the selected dose or dose range continues to require demonstration by substantial evidence. If a dose range is selected, characterization of the dose-response relationship over the dose range
selected will generally be needed. A summary of the information used for the justification of dosage and characterization of dose-response relationship should be submitted. Copies of literature and other studies should be included.
4. Summary of studies providing substantial evidence of effectiveness
There are a variety of adequate and well-controlled studies (as defined by §514.117) that may
Number and identification of adequate and well-controlled effectiveness studies
Type of studies (clinical field, pharmacokinetic, in vitro, etc.)
Study Initiation Date, Experimental Phase Initiation/Completion Dates, Study Completion Date
Number of investigational (treated and control) animals per study
Formulation of drug used in each study (e.g., final market formulation, batch number, and other pertinent descriptors)
Brief description of results for each study
A tabular format is suggested as an efficient way to summarize major aspects of studies. For example:
|
Study no. |
Study type: Effectiveness |
Study Initiation & Completion Dates |
Exper. Phase Initiation & Completion Dates |
No. of Animals |

More detailed tables may be used to describe effectiveness results. Although tables are preferable, text summaries are also acceptable. An overall summary of product effectiveness should also appear in this section.
5. Final study reports of studies providing substantial evidence of effectiveness
The content and format of a final study report is described later in this document. Each study providing substantial evidence of effectiveness should be individually summarized in a final study report format with associated appendices.
6. All information, other than substantial evidence, pertinent to effectiveness
This section should contain any other information that may be pertinent to evaluating effectiveness of the product. Under §514.1(b)(8)(iv), CVM may refuse an application if it does not contain all information pertinent to the evaluation of the safety and effectiveness of the new animal drug and related new animal drugs. Information such as reports in the scientific literature, other studies conducted with the product outside the U.S., or any evaluations made by the sponsor’s veterinary consultants or staff should be included. Summaries of this information are acceptable.
This section includes any adverse drug events (ADEs) or items such as a report on the approximate number of units of the product sold outside of the U.S. Inclusion of the foreign approved product package insert (with English translation) is recommended.
Draft product labeling should be submitted at the time the technical section is submitted. Emphasis should be placed on sections of product labeling which relate to product effectiveness, e.g., indications, dosage and administration, clinical effectiveness, cautions, and warnings. Submission of product labeling on an appropriate electronic medium is recommended.
9. FOI summary
All sections of the FOI (Freedom of Information) summary that pertain to product effectiveness should be submitted with the technical section. Submission of the FOI summary information on an appropriate electronic medium is recommended.
B. Content and format of an effectiveness final study report
One or more adequate and well-controlled studies are required to establish, by substantial evidence, that a new animal drug is effective. The required characteristics of an adequate and well-controlled study are described in §514.117(b). The preparation of a final study report (FSR) is a required component of an adequate and well-controlled study. The FSR should be a comprehensive, standalone document that provides a clear explanation of the study objective(s), experimental materials and methods and a presentation and critical scientific evaluation of the results. The FSR should be written when collection of all raw data is complete. The effectiveness technical section should contain FSRs for each adequate and well-controlled study and reports/abstracts of corroborating studies conducted in support of a determination of effectiveness.
A study is not considered complete until a FSR is signed by the authors (all individuals involved in the preparation of the FSR). The authors should sign and date and include in the FSR a brief statement of their contributions to the FSR. Any corrections or additions to the FSR should be in the form of an amendment by the authors. The amendment should clearly identify that part of the FSR that is being added or corrected and the reason for the correction or addition, and should be signed and dated by the authors.
The FSR should contain the following elements:

7.2.2 Owner Consent Forms
The owner consent forms (if appropriate) should be attached as an appendix to this report.
7.2.3 Inclusion/exclusion criteria
The selection criteria used to admit animals to the study should be described, including any diagnostic requirements, e.g., physical examination, body temperature, or reproductive status. The rationale for and description of the inclusion and exclusion criteria should be included. If any animal is used in the study that failed to meet the inclusion criteria, the reason should be provided.
7.2.4 Acclimation of investigational animals
An acclimation period allows animals to adapt to the study environment, e.g., housing, handling, and feeding practices. The final study report should describe the location of the animals during the acclimation period, the length of the acclimation period, any medication(s) and/or vaccines administered during this period, and any baseline data collected prior to dose administration.
For each analytical method used in the conduct of this study, include, at a minimum, a description of the method, a brief methodology (including sample collection, preparation and storage; validation; quality control procedures; and supportive relevant scientific references), and objective criteria and procedures to assess the analytical results. A certification that all method validations were performed before the initiation of the study should be included. If validations were not performed before the start of the study a statement describing the mitigating reasons should be included.
7.4 Study facilities
7.4.1 Identification and description
The name and address of the study facilities must be provided (§58.185(a)(1)). A complete description of these facilities should be provided. Such a description could include a general description of the housing unit(s) including dimensions of the pertinent areas used during any phase of the study. Diagrams may prove useful to convey this information.
7.4.2 Management procedures
General management procedures, e.g., equipment maintenance and environmental control (temperature, humidity, airflow), may have bearing on the study outcome and welfare of the animals and should be described. Where appropriate, the type, frequency and duration of exercise provided to the animals should be described.
7.5. Feed and Water
7.5.1 Diets
The diets fed to the investigational animals should meet the nutritional requirements of the animals. When necessary, a qualitative and quantitative description of the dietary ingredients should be provided. The frequency of feedings and the quantities of feed offered and refused should be described. When the test article is administered in feed, drug feed assays should be discussed, especially in terms of proper drug administration. Discuss differences, if any, in the dietary feed intake between the treated and control
animals.7.5.2 Water
The quality and availability of water offered to the animals and water delivery systems should be described.
A description of the dosage, dosage regimen, route of administration, and duration shall be included (§58.185(a)(8)). Any problems encountered with dosing should be discussed as well as observations regarding palatability (if applicable).
The type, quantity and duration of concomitant medications/therapies should be discussed in this section. The rationale for use and impact of the medications/therapies on the study outcome (e.g., drug interaction or effect on a study parameter) should be discussed.
7.8 Criteria for animal removal from a study
It is sometimes necessary to remove an animal from study due to sickness, injury or other reasons. The specific criteria for removal should be detailed as well as the procedure for removal and, if appropriate, replacement.
Details of gross necropsy and histopathology should be included. The number of animals, measurements obtained, e.g., clinical pathology parameters, and tissues examined and saved should be listed.
7.10 Animal and drug accountability and disposition
The final disposition of all investigational animals (number and procedure for disposal) and the investigational new animal drug and control article should also be described.
8. Study variables/observations
Observations include any inspection or examination of investigational animals. The rationale
for the variables selected to test the objective of the study should be discussed in detail. In addition, the methods used in assessing the variable should be explained or referenced. The frequency of assessment and the criteria used to characterize the measurement of the variable should be stated. If measurement of a variable is derived, the calculations used in the derivation should be provided.
For example, in a safety study for an injectable product to be administered intramuscularly, injection site observations should record the presence and degree of heat, swelling, redness and pain. These variables can be scored and used objectively to describe adverse effects associated with administration of the drug and/or the placebo.
8.2 Other observations recorded during the study
All other types of observations should be discussed such as animal care observations, food consumption observations, etc.
9. Data calculations and statistical methodologies and analyses
A description of all transformations, calculations, or operations performed on the data (§58.185(a)(11)) and the statistical methods employed for analyzing the data (§58.185(a)(3)) must be included. The statistical portion of the report is not a printout of the data analysis (which should be included as an appendix) but rather, is a description of the data and procedures. The differences that exist, if any, between the data set subjected to statistical analyses and the complete raw data should be identified. The experimental unit and the number of replicates per treatment should be defined. The statistical methodology should be described including the hypotheses tested, any estimated parameters or assumptions and any specific statistical model used. If any data transformations were performed, a rationale for the choice of transformation as well as the impact on treatment effects should be discussed. A description of how the results were used to draw conclusions about the study's objective(s) and the appropriateness of the choice of statistical method should be provided. Where the actual transformations, calculations, or operations performed on the data or the actual statistical methods employed to analyze the data differ from that stated in the protocol, a rationale for such deviation should be included.
10. Results
All data collected during the study must be summarized and analyzed (§58.185(a)(11)). The results for each protocol-defined variable used as evidence to support safety should be presented as text, tables or graphs (as appropriate). The exact location (appendix page numbers) of the supporting raw data should be referenced. Tables and graphs should be concise and user-friendly, since individual data will be located in the appendices.
An overall statement of the conclusions drawn from the analysis of the data regarding the target animal safety of the product must be included (§58.185(a)(11)). Furthermore, a description of all circumstances that may have affected the quality or integrity of the data must be included (§58.185(a)(9)). New or unexpected findings and their impact on the study outcome should be identified. Adverse events and their potential impact and any results, which may be inconsistent with the overall study conclusions, should also be discussed in detail.
12. Personnel
The name of the study director, the names of other scientists or professionals, and the names of supervisory personnel involved in the study must be included (§58.185(a)(10)).
13. Reports
The signed and dated reports of each scientist or other professional, e.g., pathologists and statisticians, involved in the study must be included (§58.185(a)(12)). Reports may be included in the Appendix.
14. QA Statement
A statement prepared and signed by the quality assurance unit as described in §58.35(b)(7) must be included (§58.185(a)(14)).
