Cell and Gene Therapies Regulation

Cell and Gene Therapies Regulation: Globally, cell and gene therapies are revolutionising modern medicine, offering groundbreaking treatments for life-threatening conditions including cancer, genetic disorders and rare diseases.

Globally, cell and gene therapies are revolutionising modern medicine, offering groundbreaking treatments for life-threatening conditions including cancer, genetic disorders and rare diseases. However, despite the pace of scientific innovation, regulatory frameworks in many countries, including Australia and New Zealand, have struggled to keep up.

Neither country has dedicated regulatory pathways specifically for advanced therapies like cell and gene treatments. Instead, these therapies are regulated under legislation originating in the 1980s, creating challenges for companies entering these markets.

In this blog, we’ll explore the challenging landscape that is, cell and gene therapies regulation in Australia and New Zealand and discuss how a regulatory consultant can help navigate these complex frameworks.

In Australia, the Therapeutic Goods Administration (TGA) is the primary body overseeing therapeutic goods, including cell and gene therapies regulation. These products are generally regulated under the Therapeutic Goods Act 1989. The absence of a dedicated regulatory framework for advanced therapies means that cell and gene therapies are regulated as either biologicals or prescription biological medicines.

Somewhat confusingly, biological medicines and biologicals are not regulated in the same way!

Human cell and tissue-based therapeutic goods, as well as live animal cells, tissues and organs are regulated as biologicals. This category includes gene therapies that involve ex-vivo manipulation of human cells such as CAR-T cell therapies.

Biologicals are further classified as classes 1 to 4, based on their risk to patients. Early classification of biologicals is essential for product development planning, as the class determines the requirements for product registration.

Advanced therapies involving in-vivo genetic manipulation (such as monoclonal antibodies, vaccines without human cells, plasma derivatives, and recombinant products) are regulated as prescription medicines. Examples of treatments regulated as medicines include small silencing RNAs, CRISPR and other gene editing technologies, and gene therapies administered by vectors.

The TGA offers two primary pathways for approval of clinical trials: the Clinical Trial Notification (CTN) and Clinical Trial Approval (CTA) schemes.

  • The CTN pathway is typically used for lower-risk therapies where sufficient preclinical data is available
  • The CTA pathway is required for higher-risk or novel treatments like gene therapies, especially where safety data is limited

Any gene therapy that involves genetic modification must also be approved by the Office of the Gene Technology Regulator (OGTR). OGTR approval is required prior to TGA approval, and OGTR applications should be filed either before or concurrently with ARTG applications.

Like Australia, New Zealand regulates cell and gene therapies under its existing therapeutic goods legislation, notably the Medicines Act 1981. Under this act, advanced therapies are considered medicines, and the traditional medicines registration pathway applies.

Advanced therapies in New Zealand must undergo the usual regulatory processes for new medicinal products including submission for approval to Medsafe, the country’s primary regulatory authority for therapeutic goods.

All clinical trials in New Zealand must be assessed by Health Research Council of New Zealand (HRC) and approved by Medsafe before commencing. Trials involving gene therapies are specifically reviewed by the Gene Technology Advisory Committee (GTAC), which evaluates the safety and ethical considerations of gene-based interventions.

Products involving genetic modification are also subject to regulation by the Environmental Protection Agency (EPA) under the Hazardous Substances and New Organisms Act 1996 (HAZNO Act). Approval from the EPA is necessary for the import, development, or release of GMOs.

In both Australia and New Zealand, Good Manufacturing Practice (GMP) is essential to ensure the safety and quality of advanced therapies.

Manufacturing of prescription medicines supplied in Australia must meet the PIC/S Guide to Good Manufacturing Practice (PE009-16), except for some Annexes which are not adopted in Australia. Australian manufacturers will require a TGA licence for the relevant manufacturing steps following an on-site inspection. Overseas manufacturers of prescription medicines undergo a GMP Clearance process to ensure compliance to the PIC/S GMP principles.

If the advanced therapy product is classified as a biological, the manufacturing principles outlined in the Australian code of GMP for human blood and blood components, human tissues and human cellular therapy products must be applied. Since this standard is specific to Australia, TGA inspection of overseas manufacturing sites may be necessary to be able to register the product in Australia.

Medsafe follows the New Zealand Code of Good Manufacturing Practice which is aligned with the PIC/S Guide to GMP, ensuring that all therapeutic goods manufactured meet internationally recognized quality and safety standards.

In addition to the GMP manufacturing requirements, approval may be required to manufacture the product; from OGTR in Australia or EPA in New Zealand. The key consideration for OGTR and EPA is to ensure the health of humans and the environment. In this regard, manufacturers must implement appropriate containment measures to prevent the accidental release of genetically modified cells. This may involve the use of secure facilities, specialised equipment, and strict protocols for handling and disposal of materials.
