Technical guidance on the interpretation of manufacturing standards: Product quality review for listed complementary medicines
Technical Working Group (TWG) on complementary medicines
Technical Working Groups have been established by the TGA's office of Manufacturing Quality (OMQ) to bring together manufacturing technical expertise from industry and the regulator to address the application of the PIC/S Guide to Good Manufacturing Practice for Medicinal Products January 2009 (adopted under transitional arrangements 31 July 2009 by Therapeutic Goods (Manufacturing Principles) Determination No 1 of 2009, as the Australian Code of Good Manufacturing Practice (GMP), becoming mandatory 1 July 2010).
The aim of the Technical Working Groups is to:
- Establish a formal and transparent forum for industry and the regulator to work cohesively in order to provide advice on the application of Manufacturing Standards.
- Improve and foster industry implementation of Manufacturing Standards, and enhance regulatory audit consistency in the application of Manufacturing Standards.
- Identify and discuss key areas of concern, and address emerging issues relevant to the interpretation and application of Manufacturing Standards.
- Develop specific guidance documents as appropriate.
Guidance documents are not intended to establish a minimum standard of practice for audit purposes. Guidance documents are not enforceable.
This Guidance is not mandatory or enforceable under law. It is not intended to be restrictive. It describes a way that a manufacturer may operate to demonstrate compliance with the relevant Code of Good Manufacturing Practice for Medicinal Products.
This document is provided for guidance only and has been developed on the basis of current knowledge of the subject matter. It should not be relied upon to address every aspect of the relevant legislation. Please also refer to the Therapeutic Goods Act 1989 and the Therapeutic Goods Regulations 1990 for legislative requirements and the PIC/S Guide to Good Manufacturing Practice for Medicinal Products January 2009.

This guidance is intended to clarify the interpretation of the PIC/S Guide to Good Manufacturing Practice for Medicinal Products in relation to the conducting of Product Quality Reviews for Listed Complementary Medicines.
Product Quality Reviews have become an accepted part of GMP requirements internationally and may provide useful information and additional controls over manufacturing processes and quality requirements for products. Product Quality Reviews will also provide a mechanism to ensure on-going stability studies are conducted by sponsors, as verified during an audit of a manufacturer by reviewing the information available to the authorised person releasing product for supply to the market.
This guidance is relevant to Listed Complementary Medicines.

[A Flowchart may be added later]
The introduction of the PIC/S Guide to GMP for Medicinal Products in July 2009 and its implementation by 1 July 2010 has introduced some changes from the requirements of the 2002 PIC/S Code previously in force in Australia. one significant change is Section 1.4 Product Quality Review which requires regular reviews (usually annually) of all medicinal products.
The authorised person responsible for final batch certification together with the marking authorisation holder (Sponsor) should ensure that the Product Quality Review is performed in a timely manner and is accurate. For those manufacturers that are also the Sponsor of the product, a delineation of responsibility between the Manufacturer and the Sponsor is not an issue. However when a contract manufacturer (or manufacturers) make(s) a product on behalf of a Sponsor the responsibilities of each party in the Product Quality Review Process shall be documented in the Technical Agreement or GMP Agreement, a copy of which shall be held by the Authorised Person who conducts Release for Supply.
Relevant objective evidence will be expected to be available for review, at the time of audit of licensed premises, to demonstrate that manufacturers have undertaken their respective responsibilities in regard to Product Quality Reviews as defined in the Technical or GMP agreements. For guidance on allocation of responsibilities please refer to Table 1 in this document. Manufacturers can not delegate inherent responsibilities for the steps that they are licensed to undertake to non licensed parties. The Authorised Person conducting the release for supply step must hold complete copies of the Product Quality Reviews. These documents will be auditable by the TGA at licensed premises.
This document will look at each part of Section 1.4 and offer guidance for manufacturers of Listed Complementary Medicines. Excerpts from the PIC/S Guide to GMP for Medicinal Products are in bold type, with comments under each paragraph.
1.4 "Regular periodic or rolling quality reviews of all licensed medicinal products, including export only products, should be conducted with the objective of verifying the consistency of the existing process, the appropriateness of existing specifications for both starting materials and finished products, to highlight any trends and to identify product and process improvements. Such reviews should normally be conducted and documented annually, taking into account previous reviews and should include at least:"
Reviews are to be conducted annually, unless 2 or less batches have been manufactured in the year, in which case a review shall be conducted every 2 years.
The respective responsibilities of the various parties in conducting the Product Quality Review is set out in Table 1.
Table 1 is intended to provide guidance as to which party is most likely to hold the relevant information and to conduct that part of the Product Quality Review. However Table 1 is not to be read as specifying that these particular parties must hold the relevant information or conduct that part of the Product Quality Review. The Technical Agreement or GMP Agreement will normally specify in each particular situation which party will be responsible for each area described in Table 1.

"The manufacturer and market authorisation holder should evaluate the results of this review and an assessment made of whether corrective and preventative action or any revalidation should be undertaken. Reasons for such corrective actions should be documented. Agreed corrective and preventive actions should be conducted in a timely and effective manner. There should be management procedures for the ongoing management and review of these actions and the effectiveness of these procedures verified during self inspection. Quality reviews may be grouped by product type, e.g. solid dosage forms, liquid dosage forms, sterile products, etc. when scientifically justified."
- Product Quality Reviews to be evaluated by both Manufacturer and Sponsor.
- Product Quality Reviews should assess any CAPAs and need for revalidation.
- A management procedure should be in place to monitor any CAPAs and revalidations resulting from Product Quality Reviews.
- Internal audits must cover Product Quality Reviews.
- Product Quality Reviews can be grouped into product types, where scientifically justified. A similar justification which would apply to process validation and or stability testing grouping would be appropriate, considering such areas as dosage type, equipment train, ingredient matrix and active quantities.
"Where the market authorisation holder is not the manufacturer, there should be a technical agreement in place between the various parties that defines their respective responsibilities in producing the quality review. The authorised person responsible for final batch certification together with the market authorisation holder should ensure that the quality review is performed in a timely manner and is accurate."
- The TGA will expect to see during audits that Product Quality Reviews have been conducted and that copy/s are held by Authorised Person/s.
- For contract manufacturers a Technical Agreement or GMP Agreement should be in place defining who does what in the Product Quality Review. This could be an extension to the normal GMP Agreement.
- Responsibility for ensuring the Product Quality Review is conducted is held jointly by both the person releasing the product (Authorised Person) and the market authorisation holder (Sponsor). Assigning responsibility in a GMP Agreement to one party only will not be acceptable.
- Grouping is to be established by the Manufacturer, in conjunction with the Sponsor's input. once the grouping is established, then a list of all batches manufactured and packed during the review period is to be identified for the products in this grouping.
- Manufacturer/s to compile a list of significant non-conformances, deviations and CAPAs for equipment, process and products, as well as results of internal audits.
- Sponsor to provide details of complaints, investigations of these by the relevant manufacturer(s), close out of complaints and trending (complaint history).
- Sponsor and/or manufacturer to review the stability monitoring program and to document any adverse trends.
- Batch documentation does not need to be routinely assessed in conducting a Product Quality Review, However if an assessment of deviations, non-conformances, or internal audit findings indicates serious issues, then batch documentation may need to be reviewed, but only as required and deemed necessary by the Sponsor and Manufacturer/s conducting the Product Quality Review.
- Sponsor to review the ARTG entry changes and post-marketing commitments, to determine if any outstanding issues need to be addressed and their impact on the products being reviewed in this grouping. This will include any variations submitted / granted / refused, including those for export only products.
- Test results (chemical & microbiological) to be compiled by the testing laboratory (contract or manufacturer) for all batches and products in the grouping, for bulk and finished products where appropriate. Should there be any issues found during this review, then in-process testing results for the relevant batches may need to be reviewed, to ascertain clarity of results obtained during production runs.
