Drugs Directorate Guidelines

Preparation of Drug Identification Number Submissions

Health Protection Branch
Health Canada

February 22, 1995

Table of Contents

Introduction

Under the provisions of section C.01.014 of the Food and Drug Regulations, no manufacturer shall sell a drug in dosage form unless a drug identification number (DIN) has been assigned for that drug and the assignment of the number has not been cancelled pursuant to section C.01.014.6. In the case of a new drug, a new drug submission filed pursuant to Division 8 of the Food and Drug Regulations is regarded as an application for a DIN. When a product is not subject to Division 8, the application is called a DIN submission.

Prior to issuing drug identification numbers, the Drugs Directorate requires the submission of sufficient data to evaluate the safety and efficacy of a drug for its intended use. This is in keeping with the requirements of subsection 9(1) of the Food and Drugs Act:

"No person shall label, package, treat, process, sell or advertise any drug in any manner that is false, misleading or deceptive or is likely to create an erroneous impression regarding its character, value, quantity, composition, merit or safety."

It is in the interest of public health for the Drugs Directorate to determine that a drug product is of sufficient quality not to be injurious to the Canadian public, and to perform in the expected manner.

The Guideline for Preparation of DIN Submissions outlines the information normally needed to establish quality, safety and efficacy of drug products according to product type. In addition to the basic application and certification requirements, the applicant need only refer to that section of this guideline that applies to the product type.

DIN Submission Definition

A Drug Identification Number (DIN) is an eight (8) digit numerical code assigned to each drug product marketed under the Food and Drugs Act and Regulations.

A DIN identifies the following product characteristics:

  • manufacturer
  • brand name
  • medicinal ingredient(s)
  • strength of medicinal ingredient(s)
  • pharmaceutical form
  • route of administration

Where any of the product characteristics differ, a separate DIN submission is required.

New Drug Status Decision

A New Drug Status decision will be made on all DIN submissions. Where the drug product is considered to be in New Drug Status, the applicant will be so informed, otherwise the DIN submission evaluation will proceed.

A list of products currently regulated as New Drugs has been prepared. Although the list will not be all-encompassing due to the complexity of Division 8 of the Food and Drugs Regulations, it is intended to assist applicants in identifying many new drugs. This list is accessible on the Electronic Bulletin Board.

Presentation of the Submission

A submission for a DIN should contain the following information for review:

  1. a completed Drug Submission Application, Health Canada HPB form 3011, (Appendix A), including proposed Canadian labels and prescribing information or a package insert where applicable
  2. a completed DIN Submission Certification (Appendix C) or Category IV Drug Submission Certification (Appendix D) as appropriate
  3. specific product type information as specified in Sections I - XVII.

Review of the information submitted may result in the request for additional material to respond to a particular concern.

The Sections that follow the Introduction outline the minimum presentation and content requirements for a DIN submission by product type. The Sections consists of two parts:

  1. information requirements and
  2. conditions under which the requirements apply

Applicants need only consult those Sections which apply to their particular product type for identification of the data requirements.

A post-market audit procedure will be implemented. This audit will include such aspects as compliance with good manufacturing practices (GMP), and verification of data submitted to support DIN issuance. A detailed mechanism to support this audit is being developed.

The provision of the information outlined in the Guideline will enable the Drugs Directorate to evaluate the DIN submission in an effective and efficient manner. This will expedite the review process. The Management of Drug Submissions Policy will continue to apply to DIN submissions.

Scope

This guideline is applicable to all pharmaceutical products for human use with the exception of Schedules C (radiopharmaceutical) and D (biological) drugs and GP products not subject to a Category IV Monograph or Labelling Standard.

Changes After DIN Issuance

For product changes after the DIN has been issued, the provisions of Section C.01.014.4 of the Food and Drugs Regulations apply. Additionally, Section C.01.014.5 of the Food and Drugs Regulations states that "every manufacturer of a drug shall, annually before the first day of October, and in a form authorized by the Director, furnish the Director with a notification signed by the manufacturer or by a person authorized to sign on his behalf, confirming that all the information previously supplied by the manufacturer with respect to that drug is correct."

For DINs issued on the basis of a demonstration of bioequivalence, comparative pharmacodynamic/clinical studies or pharmaceutical equivalence, any change which would have an impact on these parameters would cause the previously filed information to be no longer correct (ref. C.01.014.5 of the Food and Drugs Regulations). For this reason, such changes would require notification and approval prior to implementation. A working group has been established to develop clear guidelines to cover all aspects of changes post-DIN issuance.

Exclusions

Excluded from the assessment to determine bioequivalence requirements are:

  1. Section II products: Homeopathic Preparations
  2. Section III products: Traditional Herbal Medicines
  3. Section V products: Nonprescription Products Subject to a Category IV Monograph
  4. Vitamin, mineral or vitamin/mineral preparations

Nonprescription Products

The clinical consequences of variable bioavailability for solid oral dosage forms, oral suspensions, powder/granules for oral suspension, and oral solutions, intended for systemic effect containing nonprescription drugs are generally less significant in overall patient health outcomes. For this reason, the submission of bioequivalence data will only be required if, after consideration of all relevant factors outlined in Appendix E, it is determined that such studies would be required based on the risk(s) posed.

For nonprescription drugs an assessment by the applicant of the need for bioavailability data is required to be conducted, however, if the assessment is negative, submission of the assessment and justification are not required, except on request.

Prescription Products

Demonstration of bioequivalence is generally required for solid oral dosage forms, oral suspensions, powders/granules for oral suspension and oral solutions, intended for systemic effect containing prescription drugs. This is because of the nature of the ingredients, the conditions being treated and the clinical significance of differences in bioavailability.

The applicant may apply to waive demonstration of bioequivalence for prescription drugs. Justification based on scientific principles must be submitted.

Waiver of Bioequivalence Requirement

A waiver of bioequivalence may be granted for the following:

  1. For different strength(s) of the same dosage form produced by the same manufacturer, if the product meets all of the following:
    1. the bioequivalence of one of the strengths to the Canadian reference product has been demonstrated and
    2. the composition of the other strengths is proportionally similar in its medicinal and non-medicinal ingredients to that strength which underwent the acceptable bioequivalence study and
    3. all strengths of the drug product exhibit equivalent dissolution profiles.

      Note: A waiver of bioequivalence would not normally be granted for additional strengths for medicinal ingredients with known non-linear pharmacokinetics.
  2. Non-absorbable oral preparations; since non-absorbability is a relative term, determination of the bioequivalence requirements will be made on a case-by-case basis.
  3. Oral solutions, elixirs, syrups or other similar solubilized forms containing the same medicinal ingredient(s) in the same concentration(s) as the Canadian reference product and containing no ingredient known to significantly affect absorption of the medicinal ingredient
  4. Justification provided by the applicant based on assessment to determine bioequivalence requirements.

Assessment to Determine Bioequivalence Requirements

All factors outlined in Appendix E should be addressed in assessing a product and should be included in any scientific justification submitted for a waiver of bioequivalence.

Section XV-B Conditions

Exclusions

Pharmacodynamic/clinical studies are not required for products of simple formulation such as a solution which contains the drug substance(s) in a solvent which does not include non-medicinal ingredients that may affect penetration/absorption of the drug.

Nonprescription Products

The clinical consequences of interproduct variability for these preparations containing nonprescription drugs are generally less significant in overall patient health outcomes. For this reason, the submission of pharmacodynamic/clinical studies will only be required if after consideration of all relevant factors, it is determined that such studies would be required based on the risk(s) posed.

For nonprescription products an assessment by the applicant of the need for such data is required to be conducted, however, if the assessment is negative, submission of the assessment and justification are not required, except on request.

Prescription Products

Pharmacodynamic/clinical studies between the applicant's drug product and the Canadian reference product are required for all prescription products unless the manufacturer can provide justification based on scientific principles as to why such data are not necessary. All relevant factors should be addressed in the justification. The clinical endpoints measured in the studies must be relevant to the claims of efficacy. Surrogate models may be considered in lieu of clinical studies in certain cases. At the present time there is only one accepted surrogate model. This is the Vasoconstrictor Assay used to compare topical steroid products.

Factors to be Addressed in Assessing Bioequivalence Requirements

  1. Is there a known or suspected bioavailability problem?
  2. Does the drug product exert therapeutic activity in a narrow therapeutic range e.g. how wide is the margin between minimum effective and minimum toxic plasma concentrations?
  3. Does the drug product require careful dosage titration and patient monitoring?
  4. Is there pharmacokinetic evidence that:
    1. the medicinal ingredient is absorbed in a particular segment of the gastrointestinal tract or is absorbed from a localized site?
    2. the degree of absorption of the medicinal ingredient is poor e.g. less than 70%, ordinarily in comparison to an I.V. dose, even when it is administered in pure form e.g. in solution?
    3. there is rapid metabolism of the medicinal ingredient i.e. >40% in the intestinal wall or liver during the process of absorption (first-pass metabolism) so that the therapeutic effect and/or toxicity of the drug product is determined by the rate as well as the degree of absorption?
    4. the medicinal ingredient is rapidly metabolized or excreted so that rapid dissolution and absorption are required for effectiveness?
    5. the medicinal ingredient is unstable in specific portions of the gastrointestinal tract and requires special coatings or formulations e.g. buffers, enteric coatings and film coatings, to ensure adequate absorption?
    6. the drug is subject to dose dependent kinetics in or near the therapeutic range, and the rate and extent of absorption are important to bioequivalence?
  5. Is there physicochemical evidence that:
    1. the medicinal ingredient has a low solubility in water, e.g. less than one percent, or if dissolution in the stomach is critical to absorption, the volume of gastric fluids required to dissolve the recommended dose greatly exceeds the volume of fluids present in the stomach (taken to be 100 mL for adults and prorated for infants and children)?
    2. the dissolution rate of the medicinal ingredient from the drug product is slow?
    3. the particle size and/or surface area of the medicinal ingredient is critical in determining its bioavailability?
    4. the medicinal ingredient exhibits certain physical structural characteristics which may lead to poor dissolution and thus may affect absorption, (e.g. polymorphic forms, solvates, complexes and crystal modifications)?
    5. the drug product has a high ratio of excipients to medicinal ingredients, e.g. greater than 5 to 1?
    6. hydrophillic or hydrophobic excipients and lubricants are present which may be required for absorption or may interfere with absorption of the drug?

Guidance: Computer Format for the Submission of Data for Bioavailability StudiesIntroduction In order to streamline the review of comparative bioequivalence studies, companies should submit their body fluid drug concentration versus time data in a standard format that can be loaded directly into the Drugs Directorate computers for review. The primary goal in providing the data in this format is to eliminate the time consuming task of reentering the data into the computer for use by the reviewer The format recommended here is for human abbreviated drug submissions. For the purposes of this guidance an electronic submission will consist of a 3.5 inch (micro-floppy) diskette containing the raw blood (or other body fluid) level data for each subject and associated parameters derived from that data. Detailed Specifications Currently, IBM compatible personal computers, using DOS 3.3 as the Operating System and the SAS System for the analysis of data, are used. Because organizations use different SAS programs it is recommended that the data be formatted as an ASCII data file which can then be transposed into a SAS data set.The data should be submitted on a 3.5 inch double sided high or low density micro-floppy disk which has been formatted on an IBM or compatible computer, using DOS 2.1 or greater. The disk should be labelled to identify the company, the drug and the date. Three files are required:

  1. an information file
  2. a data concentration file
  3. a pharmacokinetic data file

File names should differ only in their extensions; of the 8 characters in the filename it is suggested that the first three characters be used to identify the company and the remaining five be used to identify the drug and formulation.

  1. The information required in the first file (suggested extension .inf) is,
    1. A list of the sampling time points for the study (these are the first entries in the file to facilitate access by SAS)
    2. The drug name, strength, dosage form, potency and dose given for the drug
    3. Limit of quantitation (LOQ) of the analytical method
    4. Lowest and highest nominal concentrations of the standard curve
    5. Treatment (formulation) labelling
    6. The sponsor company's name and the name of the firm that performed the study
    7. The name and telephone number of a person to whom inquiries concerning the electronic data set can be addressed
    8. The date the file was generated
    9. A unique number that identifies the file (the HPB Project ID and File Number, if known)
    10. A description of the record layout in the data file (typically as shown below in record layout)
  2. The second file (suggested extension .dat) contains the drug concentrations.

    There is a record for each subject in each period (i.e. the total number of records = number of subject X number of periods). The record should be grouped by treatment (formulation) and within each group by subject in numerical order.

    The detailed format for each record is as follows:
    Descriptor Position Length Type Example
    subject number 1-2 2 alphanumeric 09
    sequence 4-5 2 alphanumeric AB or BA
    study period 7-11 5 alphanumeric JUN08
    treatment* 13-13 1 alphanumeric A or B
    conc (0) 15-21 7 numeric  
    conc (1) 23-29 7 numeric  
    ... ... 7 numeric  
    conc (t) 114-120 7 numeric  
    • Where t = the total number of time points (in this example t=14)
    • All entries are delimited with a space
    • Missing data should be entered as a period (.)
    • The entered concentrations cannot be below the lowest or above highest nominal concentrations of the standard curve. Concentrations at and below the limit of quantitation (LOQ) should be entered as 0.0

      * In order that the ANOVA (PROC GLM in SAS) be applied in the correct fashion the reference product should be identified by a name that is alphabetically later than the test product (e.g. in a two way crossover the test treatment can be labelled A (experimental) and the reference B).

  3. The third file (suggested extension .pkv) contains the pharmacokinetic variables for each subject and each formulation e.g.:
    • AUC 7 numeric
    • Cmax 7 numeric
    • Tmax 7 numeric

Hardcopy of the data should also be provided. The first file (.INF) may also explain the data set and any instructions necessary for downloading to a SAS data set (if required). This text file may be in an ASCII format and readable through the TYPE command. Hardcopy of this file should also be included. This format is based on information obtained during discussions with industry and reviewers at the HPB. The intent is to streamline the reviews of abbreviated drug submissions. The format is not inflexible, it represents a basic minimum required as a starting point. Changes to the record layout should be clearly recorded in the first or information file (.INF). It is recommended that if a computer ready submission is being tendered that reference be made to the fact in a cover letter. The diskette should be submitted along with the complete printed copy of the study report. The diskette should be attached to the inside of the front cover of the bioequivalence report.
