Mandatory requirements for an effective application

Applicable for applications lodged from 9 February 2018

21 February 2018

Overview

This guidance describes the information that must be submitted to the TGA for prescription medicine applications to be considered effective and proceed to evaluation. To the extent that the Pre-submission Planning Form (PPF) is a reflection of the dossier to be submitted, these requirements apply equally to Milestone 1 and Milestone 2 of the registration process.

Appendix A - Specific mandatory requirements describes the common application issues and deficiencies we have identified.

Scope

These requirements apply to applications lodged with the TGA from 9 February 2018:

  • to register a new prescription medicine (excluding applications to register an Additional Trade Name and applications to which Regulation 16G applies)
  • to vary the register entry for a prescription medicine that involves clinical, nonclinical, or bioequivalence data.

Legislative requirements

Applicable for applications lodged from 9 February 2018

21 February 2018

Applications for new registrations

Applications for new registrations1 are made under Section 23 of the Therapeutic Goods Act 1989 (the Act). Section 23 requires that applications:

  • are made using a form approved by the Secretary (section 23(1) of the Act);
  • include information in a form approved by the Secretary (section 23(2)(b) of the Act); and
  • include such information as will allow the determination of the application (section 23(2)(b) of the Act).

The approved form is defined in a legislative instrument issued under section 23(1) of the Act. The requirement for the applicant to provide such information - in a form approved by the Secretary - to allow determination of the application is defined in a separate legislative instrument issued under section 23(2)(b) of the Act.

In summary, the Section 23 instruments specify that applications referred to in regulation 16C of the Regulations(that is, Category 1 and Comparable Overseas Regulator (COR) report-based applications for new registrations, other than applications for an additional trade name) must comply with the following regulatory documents:

In addition to the documents specified by the section 23 instruments, the TGA has produced the following other documents which assist applicants in the preparation of a PPF and an application dossier. These include:

Any departures from relevant requirements or guidelines must be explicitly justified in the application dossier. Some departures may require prior liaison with the TGA. See Justifications for further information.

In submitting a PPF, the applicant is indicating they understand and agree to comply with the General dossier requirements for a dossier to be considered effective and accepted for evaluation.

1A new registration is one that requires a new ARTG entry by reason of being separate and distinct goods under section 16 of the Therapeutic Goods Act 1989. This includes new chemical entities, new strengths, new dosage forms, different directions for use, formulation changes, changes in trade name, extension of indication etc. By the provisions in the Therapeutic Goods (Groups) Order 2001, not all new registrations will result in a new AUST R number being allocated if they are taken to be grouped.

Applications for variations

Applications requesting a variation to an existing registration are made under section 9D of the Act.

Legislative instruments issued under section 9D(6)(a) and section 9D(6)(b) describe the form and manner approved by the Secretary for applications made under section 9D(3), including the requirement to provide a dossier in CTD format.

For section 9D(3) applications to which regulation 16D of the Therapeutic Goods Regulations 1990 applies (i.e. Category 1 and COR report-based applications for variations), the legislative instruments set out a set of requirements similar to those for new registrations (above). The supporting documents listed above as applicable to new registration applications also apply to applications for variations.

Note

As with applications for new registrations:

  • Any departures from relevant requirements or guidelines must be explicitly justified in the application dossier. Some departures may require prior liaison with the TGA. See Justifications for further information.
  • In submitting a PPF, the applicant is indicating they understand and agree to comply with the TGA's requirements for a dossier to be considered effective and accepted for evaluation.

Content of application dossier

Applicable for applications lodged from 9 February 2018

21 February 2018

The exact content of the application dossier will vary according to the:

  • application category
  • nature of the medicine
  • application type.

A dossier documents matrix is provided in CTD Module 1: Administrative information and prescribing information for Australia which provides a high-level overview of the application dossier CTD section requirements for different application types.

Overview of CTD documents

CTD Module 1: Administrative information and prescribing information for Australia establishes the Module 1 content for different application types.

CTD Module 2 is a summary module which provides an overview of the information/data provided in the quality (Module 3), nonclinical (Module 4), and clinical (Module 5) modules of the dossier. Information on the content of Module 2 is provided at the beginning of CTD Modules 3, 4, and 5.

The organisation of Modules 3, 4, and 5 is specified by the CTD Modules 3, 4, and 5. These modules contain headings and sub-sections under which applicants must insert technical data. To determine technical data requirements, applicants must consult relevant Australia-specific guidelines and EU guidelines adopted in Australia.

Technical data requirements

The application dossier must provide appropriate documentation (in the correct format and locations, as determined by the CTD modules), including outcomes of trials and studies, to allow the Delegate of the Secretary to assess quality, safety, and efficacy claims. The technical data requirements that establish the documentation to be provided in the dossier are:

The use of EU guidelines adopted in Australia and other Australia-specific guidelines is not mandated in the legislation. However, section 25(1)(d) of the Act requires that when making a decision on whether to approve a medicine for registration, the delegate determines:

"whether the quality, safety and efficacy of the goods for the purposes for which they [the goods] are to be used have been satisfactorily established;"

Where a dossier does not address the applicable requirements/guidelines, or fails to adequately justify why an applicable requirement/guideline has not been addressed in the application, we may be unable to establish satisfactorily the quality, safety or efficacy of the proposed good.

Justifications

As noted above, Australia-specific guidelines and adopted EU guidelines determine the data and information required in Modules 1, 2, 3, 4, and 5 of a dossier to demonstrate quality, safety, and efficacy.

It is the applicant's responsibility to familiarise themselves with all relevant Australia-specific guidelines and EU guidelines adopted in Australia, and to advise us of instances of, and reasons for, deviation from the applicable guidelines or requirements.

A justification is a reason given by the applicant for not complying, in the application dossier, with a specific requirement or guideline, and generally fall into one of two broad categories:

  • Justifications that will determine the categories/sections of information required in the application dossier for it to be considered effective and accepted for evaluation. If a dossier does not contain a certain section, and an acceptable justification has not been provided for its absence, the application dossier may not meet the requirements for an effective application under section 23 of the Act.
  • Justifications that will determine the depth and breadth, or adherence to an adopted standard specification or guideline for the required information. This is relevant to evaluation during the 1st and 2nd round assessment phases when the content of the application dossier is being evaluated.

    If the justification provided by the applicant for not adhering to a specification or guideline is not present, not appropriate (e.g. wrong guideline is addressed), or inadequate, the application submitted may not satisfactorily establish the quality, safety and efficacy of the proposed good. That is, the application will not be considered to be effective.

Some justifications must be submitted to us prior to lodging a Pre-submission planning form (PPF) and our acceptance of the justification included with the PPF. These include:

  • justification of a new fixed dose combination
  • justification of the literature search strategy for a literature-based submission.

The PPF refers to several justifications required to be submitted with the form:

  • for a generic application, a justification where a salt/ester of the generic product is different to the Australian reference product
  • for applications where the existing ingredients intended are to be used for different purposes (e.g. new route of administration), a justification is required if not providing additional toxicology data to support the safety of the ingredient for the intended use
  • justifications for not providing data according to a particular guideline or aspect of a guideline
  • justification for including a preservative in a single dose injection.

Where the applicant chooses not to provide data according to a particular guideline or aspect of a guideline (for example, the applicant may consider the guideline is not applicable to the product), the justification must explain why the guideline is not applicable and why the proposed alternative is valid.

A justification must be scientifically robust and address the relevant requirement. For certain requirements, we provide detailed information to assist applicants in constructing a robust scientific justification (for example, the TGA Biopharmaceutic studies guideline provides information on the required content for a justification for not conducting biopharmaceutic studies).

Where we have provided such detailed information, the applicant must ensure all details have been addressed in the justification. In other cases, applicants must adhere to the principles of a robust scientific justification (see Important note below).

Important note

Where possible applicants should not deviate from the relevant guidelines.

Should an applicant submit an application that includes justifications for not meeting a relevant guideline, we will assess whether the justification provided is a robust scientific justification.

A robust scientific justification is one that:

  • clearly identifies the guideline or part of the guideline that is not being met
  • specifically addresses why the guideline is not being met
  • has a contemporary scientific basis
  • includes citations to the relevant reference documents, including TGA documents, where appropriate. Applicants must ensure all such references are included in the dossier.

This justification will be assessed in the above terms - but not evaluated - in determining whether an application is to be found effective.

Administrative requirements

Applicants must comply with (and cannot provide a justification for not complying with) the administrative requirements. These include those applying to:

  • forms to be completed for administrative purposes
  • the presentation of the electronic dossiers.
  • requirements specific to the Priority review registration pathway

Establishing bioequivalence or therapeutic equivalence

Biopharmaceutic studies of new medicines typically include the investigation of absolute bioavailability, relative bioavailability and bioequivalence of different dosage forms or formulations, and the effect of food or antacids on their bioavailability.

For new generic medicines, establishing bioequivalence with the Australian reference product allows bridging to the nonclinical and clinical studies. Applicants applying for a new generic medicine are therefore required to provide information to demonstrate bioequivalence; however, our experience is that many applicants are uncertain about how to do so.

There are several Australian and adopted EU guidelines that are relevant to establishing bioequivalence. A summary of these documents, and their relationships, is provided below.

Summary of guidelines relevant to establishing bioequivalence
Document Relevant to Comments
TGA guideline: Biopharmaceutic studies All applications to register a new medicine.

Applicants should consult this guideline to ascertain:

  • whether or not biopharmaceutic studies will be required to support their application in Australia.
  • minimal issues to be addressed if providing a justification for not submitting biopharmaceutic data.
  • issues to consider concerning the choice of reference product.

If it is unclear whether a medicine is of the category Prescription medicines which do not require biopharmaceutic data, the applicant should contact us prior to lodging the PPF.

Guideline on the Investigation of Bioequivalence (CPMP/EWP/QWP/1401/98 Rev. 1/ Corr) Applications for synthetic medicines with an immediate release formulation and systemic action.

While this guidance suggests that the design and conduct of the study should follow EU regulations on Good Clinical Practice, applicants should note that the EU Note for Guidance on Good Clinical Practice (CPMP/ICH/135/95) has been adopted in Australia with TGA annotations.

The procedure for abridged applications claiming essential similarity to a reference product (ie, generics), which allows applications to be made to numerous Member States of the EU, based on bioequivalence with a reference product from one Member State, does not apply in Australia.

A bioequivalence study to support the registration of a generic product in Australia should use a reference product obtained in Australia. Where an overseas reference product is used, the applicant must be able to demonstrate the overseas and Australian reference products are identical (see TGA guideline Biopharmaceutic studies).

Clinical Requirements for Locally Applied, Locally Acting Products, Containing Known Constituents (CPMP/EWP/239/95) Applications for synthetic medicines that are applied locally and act at the site of application.

Locally applied products that do not act at the immediate site of application (skin, cornea etc.) are not covered by this guideline.

For example, eye drops that exert their effect beyond the cornea (i.e. the deeper tissues of the eye). Examples of such eye drops include eye drops for the treatment of glaucoma.

Requirements for establishing the bioequivalence of such products to a reference product are set out in the adopted EU Guideline on the Investigation of Bioequivalence (CPMP/EWP/QWP/1401/98 Rev. 1).

Products applied in a transdermal dosage form are not covered by this guideline – refer to the Note for Guidance on Modified Release Oral and Transdermal Dosage Forms. Section II (Pharmacokinetic and Clinical Evaluation) (CPMP/EWP/280/96)

Note for Guidance on Modified Release Oral and Transdermal Dosage Forms: Section II (Pharmacokinetic and Clinical Evaluation) (CPMP/EWP/280/96) Applications for synthetic medicines in transdermal and modified release oral dosage forms.

For multiple strengths of generic transdermal and modified release oral dosage forms, bioequivalence studies should be performed at least on the lowest and highest strengths versus the corresponding reference products.

If an applicant considers that this is unnecessary in a particular case, a justification for not submitting bioequivalence data should be submitted in accordance with the TGA guideline Biopharmaceutic studies (Justification for not submitting biopharmaceutic data).

Guideline on Similar Biological Medicinal Products (CHMP/437/04) and related guidelines

Applications for new biological medicines that are similar to an existing reference product Applications for similar biological medicinal products are not considered new generic applications. Applicants should follow the approaches developed in the adopted EU guidelines.
Various clinical guidelines for medicines for specific therapeutic products or use Applications requiring non-inferiority studies

Some clinical guidelines provide additional information about the studies needed to demonstrate therapeutic equivalence for specific therapeutic products or use. However, applicants must ensure the guidelines are relevant to their particular application/product.

For example, the guideline: Clinical Investigation of corticosteroids intended for use on the skin refers to the use of a vasoconstriction assay. This is an example of a pharmacodynamic endpoint that is not related to the therapeutic effect of the medicinal product. When using a pharmacodynamic model to replace clinical data, applicants must ensure the model chosen is internally valid. In the case of the vasoconstriction assay this endpoint may not be externally valid where the composition of the generic product differs to that of the reference product.

The use of pharmacodynamic endpoints should be justified in terms of their direct relevance to the intended therapeutic effect of the active component of the medicinal product.

Applicants should note that the TGA considers newly released and updated EU guidelines and decides whether or not to adopt them. Some of the above guidelines may therefore be amended, removed or replaced from time to time. Applicants should check the TGA website routinely and subscribe to receive email updates on new content.

Section Issue Requirement
5.3.1 Generic medicine: Establishing clinical equivalence

For all new generic applications, applicants must provide appropriate information to demonstrate clinical equivalence of the proposed product with the corresponding Australian reference product, unless specifically precluded by listed in Biopharmaceutic studies - Medicines which do not require biopharmaceutic data. Clinical equivalence is to be demonstrated through:

If bioequivalence studies are not appropriate (for example, topical products) then pharmacodynamic and/or clinical non-inferiority studies may be necessary.

Note: Additional specific requirements in relation to biopharmaceutic studies for a number of common scenarios are set out below.

5.3.1 Generic medicine: Immediate release oral dosage forms

Comparative bioavailability data must be provided to establish the bioequivalence of the generic medicine and the corresponding reference product in Australia, unless the applicant either:

If the in vivo data do not cover all strengths of the product, a comprehensive scientific justification prepared in accordance with Biopharmaceutic studies - Justification for not submitting biopharmaceutic data must be provided in Module 1.11.2.

5.3.1 Generic medicine: Modified release oral dosage forms

The following studies are required:

  • fed and fasted
  • steady state study versus the reference modified release reference product or an appropriate scientific justification must be included in the application.
5.3.1 Generic Medicine: Clinical Usability and Safety

Generic medicines should have comparable dosage forms and identical (or a subset of) indications, directions for use and strengths in comparison with the Australian reference product's presentations.

Use of different tablet sizes or excipients that are not found in the Australian reference product presentations and that have clinical implications (e.g. gluten, sodium content) should be justified and addressed by risk management initiatives (for example, relevant information or warnings on label or in PI).

5.3.1 Reports of biopharmaceutic studies using overseas reference product

For a biopharmaceutic study using an overseas reference product, the following must be provided (in accordance with Biopharmaceutic studies - Choice of the reference product for bioequivalence of generic medicines):

  • evidence to establish that the physical, physiochemical, qualitative and quantitative characteristics of the overseas reference product and the corresponding Australian reference product are identical
  • detailed validation data for the procedures used in the quantitative analysis of the excipients
  • data for at least two batches (including the batch used in the relevant study) from the overseas country concerned AND at least two batches from Australia.
5.3.1 New chemical entity/biological entity: Immediate release oral dosage forms

The following studies (or a robust scientific justification for not including such studies) must be submitted:

  • absolute bioavailability study
  • study to establish that the proposed formulation is optimal (e.g. a study versus an oral solution of the drug)
  • bioequivalence studies between the proposed registration formulation and pivotal clinical trial formulations
  • bioequivalence studies amongst the various strengths proposed for registration
  • food effect study.
5.3.1 New chemical entity/biological entity: Modified release oral dosage forms

In addition to the studies required for immediate release oral dosage forms, the following studies (or a robust scientific justification for not including such studies) must be submitted:

  • steady state versus an appropriate immediate release reference product
  • in vitro-in vivo correlation studies.
5.3.1 Individual comparative bioavailability studies
  • The source from which the batch of reference products was obtained must be provided.
  • If the batch of reference product was obtained from outside Australia, evidence that it is identical to the corresponding product distributed in Australia must be provided.
  • The individual calculated pharmacokinetic parameters (Tmax, Cmax, AUC, etc.) together with their means, standard deviations, etc. must be provided in tabular form.
  • The statistical analyses (ANOVA, estimated ratios and 90% confidence intervals for the ratios) of Cmax and AUC (and Cmin and degree of fluctuation for a steady state study) must have been carried out using parametric analyses of log-transformed data and the results reported.
5.3.1.1 New chemical entities, new routes of administration: Bioavailability study

All applications to register a new:

  • chemical entity
  • route of administration

must be supported by an absolute bioavailability study (or a robust scientific justification for not including such studies). Any justification for not supplying such a study must be based on science (for example where it is not feasible to prepare an intravenous formulation or there is robust evidence to support lack of systemic absorption) and not a claimed lack of necessity.

5.3.4, 5.3.5 Pharmacodynamics and dose ranging, efficacy and safety studies

The EU guidelines relevant to the specific product, as adopted by the TGA, must be taken into account. In particular there must be:

  • adequate dose ranging studies to support the dose selected
  • an appropriate pivotal study that relates explicitly to the indication proposed
  • safety data that takes into account the proposed duration of use and includes information on stopping the drug.
