This Circular guides the report
of bioavailability/bioequivalence study data in drugs circulation registration
in Vietnam.
Article 2.
Subjects of application
This Circular applies to
domestic and foreign agencies, organizations, and individuals whose activities
are related to the circulation registration of drugs in Vietnam.
Article 3.
Interpretation of terms
1. Invention drug (Innovator
pharmaceutical product) means the drug licensed for the first circulation,
on the basis of full data on quality, safety, and efficiency.
2. Generic drug (generic
product) means a finished drug in order to replace an invention drug
produced without concession license of the invention company and marketed after
the patent and the monopolies have expired their term.
3. Control drug (Comparator
product) means drug that generic drug will be used to replace it in
therapy. Normally, the control drug is an invention drug with data on
effectiveness, safety, and quality which have been established.
4. Dosage equivalence
(Pharmaceutical equivalence): the drugs are considered as dosage
equivalence if they contain the same pharmaceutical substance with the same
content in the same dosage form, same usage and reaching the same level of
quality standards.
5. The made substitutes
(Pharmaceutical alternatives): The drugs are considered as made substitutes
if they contain the same type of pharmaceutical substance but different from
chemical forms of the pharmaceutical substance (base, salt or ester ...) or
different from content or dosage forms.

7. Bioequivalence
(Bioequivalence): Two drugs are considered as bioequivalence if they are
pharmaceutical equivalence drug or pharmaceutical alternatives, and their
bioavailability after taking the same dose in the same conditions of test is
similar so their treatment effect is considered to be basically equivalent to
each other.
8. Conventional dosage forms:
a dosage form using exipients and classical preparation technique, without
intention to change the release speed of pharmaceutical substance out of dosage
forms.
9. Modified release dosage
forms (Modified release dosage form): means the dosage form to use some
excipients and/or preparation techniques different from conventional dosage
forms to create pharmaceutical substance release speed different from the form
conventional dosage. It includes accelerated, rhythm, stretching, delayed
release dosage form...
10. Extended-release dosage
form (extended release, sustained release dosage form): means a form of
modified release dosage with a speed of pharmaceutical substance release which
is changed by the direction of the prolonged effects of the drug to reduce the
frequency of use of drugs compared with conventional dosage forms of the same
pharmaceutical substance.
11. Delayed release dosage forms
(Delayed release dosage form): means a modified release dosage forms that
pharmaceutical substance is delayed for a certain period of time after
treatment and then released as normal in conventional dosage forms. Package dosage
form dissolved in the intestine is of this type.
12. Approved drugs: Within the
scope of this Circular, the drugs which have been approved means invention drug
or generic drug with sufficient data of bioavailability/bioequivalence study
meeting requirements and granted circulation registration numbers.
Article 4.
Regulations for the study of bioavailability/bioequivalence
1. The study must be designed
and implemented in accordance with provisions in the guideline to study
bioavailability/bioequivalence of ASEAN or the equivalent guidance of the other
organizations (such as the World Health organization (WHO) , international
Conference on harmony (ICH), the U.S. Food Drug Administration (U.S. FDA)). For
the studies conducted in Vietnam, before the study, research scheme must be
evaluated and approved by specialized technical agencies authorized by the
Ministry of Health.
2. The study must be conducted
at the unit of testing that has been assessed and accredited by a competent
agency in the home country, and must be done in accordance with the principles
of good clinical practice (GCP) and good laboratory practice (GLP) according to
regulations of Vietnam or other similar regulations. The registered
establishments shall have to provide valid sufficient evidence on the study
which was conducted to meet the above requirements.

combination of some pharmaceutical substances including the pharmaceutical
substance on the list of the pharmaceutical substance required to report

the study must be the invention drug with a similar coordination on ingredients
of pharmaceutical substance and proportion of coordination between the
ingredients or corresponding single ingredient control drug prescribed together
in the list.

of modified release dosage: Drug control used in the study must be selected
according to the principles set out in Annex 1 of this Circular.
4. The drug registration establishments
shall have to prove control drug which is selected by them for testing meeting
the principles as prescribed, to provide accurate, adequate information on the
country of origin as well as the production lot number and expiry date of the
control drugs used in research.
Article 6.

pharmaceutical substance required to report bioequivalence study data as
registering drug
The pharmaceutical substance
selected for inclusion in the list must meet one or more of the following
principles of priority:

b) Formula of dosage of the
being considered contents must be the same on composition (excipients and
pharmaceutical substance) and the same rate of combination between the
compositions or, in the case of pharmaceutical substance account for less than
5% in the formula, the rate of coordination among the remaining compositions in
the formula must be similar as compared with the dosage formula of the content
used in bioequivalence study;

correlation between clinical response (including response to therapy and
adverse reactions) and drug concentrations or active metabolites (from
pharmaceutical substance for trying) in plasma, required to report
bioavailability study data comparing between the drugs need to be tried with
respective control drug in conventional dosage form. This obtained comparison
bioavailability study data will be used to evaluate the safety and efficacy of
drugs in being considered modified release dosage forms. If the obtained
pharmacokinetic data in the study is not sufficient to prove the safety and
efficacy of being considered drugs, it needs to conduct a proper clinical trial
to supplement;
