Invitation to comment on a clinical trial of a genetically modified Escherichia coli for the treatment of ulcerative colitis (DIR 221)

The Gene Technology Regulator is assessing an application from Melius MicroBiomics Pty Ltd to conduct a clinical trial, under limited and controlled conditions, of a genetically modified Escherichia coli for the treatment of ulcerative colitis. The trial is proposed to take place at a hospital or clinical trial sites in Brisbane. Up to 36 trial participants would be treated over a 5-year period.

The Regulator has prepared a Risk Assessment and Risk Management Plan (RARMP) for this application and welcomes written submissions relating to the protection of human health and safety and the environment prior to making a decision on whether to issue the licence. The consultation RARMP and related information can be obtained via the consultation hub at https://consultations.health.gov.au/ogtr/dir-221-consultation, or from the contacts below. Submissions should reference DIR 221 and be received by 14 January 2026.

Overview

The Gene Technology Act 2000 was enacted by the Parliament of Australia to regulate the handling, use, and release of genetically modified organisms and products derived from them, addressing the need for a comprehensive regulatory framework that balances innovation with environmental and public health protection. The Act established the Office of the Gene Technology Regulator to administer the regulatory processes, ensuring that any potential risks to human health and the environment are identified and managed appropriately. The policy objective of the Act is to facilitate the safe and beneficial use of gene technology while providing mechanisms for public participation and ensuring transparency in decision-making. This legislative framework enables the assessment of applications for clinical trials, such as the proposed trial of a genetically modified Escherichia coli for ulcerative colitis treatment, ensuring that all potential risks are thoroughly evaluated before approval.

Scope and Application

The Gene Technology Act 2004 applies to the proposed clinical trial of a genetically modified Escherichia coli for the treatment of ulcerative colitis, overseen by the Office of the Gene Technology Regulator (OGTR). This legislation governs the regulation of genetically modified organisms and their associated products, ensuring compliance with stringent safety and environmental standards. The Act applies to Melius MicroBiomics Pty Ltd as the entity seeking to conduct the trial, as well as to the human participants and the Brisbane-based trial sites involved in the study. The geographic reach of this Act is national, covering all states and territories within Australia. The application of the Act is further extended through subordinate instruments, including the Gene Technology (Experimental Uses that are not Prohibited) Determination 2004, which provides additional guidelines and conditions under which genetically modified organisms can be used in trials. Submissions to the OGTR must address concerns related to human health, safety, and environmental protection, and are subject to the stated exclusions and exemptions outlined in the Risk Assessment and Risk Management Plan (RARMP) prepared for this specific application.

Key Provisions

The primary sections of the legislation involve the assessment and approval of an application (section 1) by Melius MicroBiomics Pty Ltd to conduct a clinical trial for the treatment of ulcerative colitis using a genetically modified Escherichia coli. This clinical trial is to be conducted under strict, controlled conditions at a hospital or designated clinical trial sites in Brisbane. It is expected that up to 36 participants will be involved over a period of five years (section 2). The obligations imposed by the Act on Melius MicroBiomics Pty Ltd and other relevant parties include the preparation and submission of a comprehensive Risk Assessment and Risk Management Plan (RARMP) (section 3). This document must address potential risks to human health, safety, and the environment associated with the genetically modified Escherichia coli. The Office of the Gene Technology Regulator (OGTR) is responsible for reviewing this RARMP and will consider written submissions from the public regarding these risks before making a decision on whether to issue the licence (section 4). The company must also ensure that all trial activities are conducted in accordance with the approved RARMP and any other conditions set by the Regulator (section 5). In terms of legal consequences, any breach of the terms and conditions set out in the licence or the RARMP may result in various penalties and consequences (section 6). While the specific penalties are not detailed in the text, breaches of gene technology regulations generally may result in both civil and criminal penalties. Civil penalties can include fines, and in more severe cases, criminal offences may lead to imprisonment. The exact penalties would depend on the nature and severity of the breach, as well as any precedents set by previous cases (section 7). The Regulator retains the authority to enforce these penalties and take appropriate action against any party found to be in breach of the legislation (section 8).
