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:
- 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
- a completed DIN Submission Certification (Appendix C) or
Category IV Drug Submission Certification (Appendix D) as appropriate
- 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:
- information requirements and
- 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.

Section VII-B Conditions
Exclusions
Excluded from the assessment to determine bioequivalence requirements
are:
- Section II products: Homeopathic Preparations

- 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:
-
For different strength(s) of the same dosage form produced by the
same manufacturer, if the product meets all of the following:
- the bioequivalence of one of the strengths to the Canadian reference
product has been demonstrated and
- 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
-
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.
- 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.
-
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
-
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.

** Dental Preparations intended to be applied topically to mucous membranes
and to inner and outer dental surfacesSection XV-B ConditionsExclusions
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
- Is there a known or suspected bioavailability problem?
- 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?
- Does the drug product require careful dosage titration and patient monitoring?
- Is there pharmacokinetic evidence that:
- the medicinal ingredient is absorbed in a particular segment of
the gastrointestinal tract or is absorbed from a localized site?
- 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?
- 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?
- the medicinal ingredient is rapidly metabolized or excreted so
that rapid dissolution and absorption are required for effectiveness?
- 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?
- 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?
- Is there physicochemical evidence that:
- 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)?
- the dissolution rate of the medicinal ingredient from the drug
product is slow?
- the particle size and/or surface area of the medicinal ingredient
is critical in determining its bioavailability?
- 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)?
- the drug product has a high ratio of excipients to medicinal ingredients,
e.g. greater than 5 to 1?
- hydrophillic or hydrophobic excipients and lubricants are present
which may be required for absorption or may interfere with absorption
of the drug?

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

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

| Tmax |

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.
