NHMRC Lifts Ban on Clinical Trials Involving Xenotransplantation in Australia

Due to Australia's efforts to establish a more well-defined regulatory and surveillance network to support clinical research since 2004, the National Health and Medical Research Council (NHMRC) recently lifted its five-year ban on clinical trials involving animal to human transplantation, also known as xenotransplantation. The Australian Therapeutic Goods Administration (TGA) is currently in the process of implementing a biological framework to address the NHMRC's concerns, particularly those pertaining to minimizing the risks of animal virus transmissions and ensuring public safety in the use of various biological therapies.

The NHMRC also plans to work closely with the Australian Government's Department of Health and Ageing in order to evaluate the surveillance monitoring frameworks that are in development to support clinical trial research connected with animal-to-human studies. Trials will only be permitted to proceed once the Australian Health Ethics Committee (AHEC) and the Animal Welfare Committee (AWC) approve the protocols within the clinical trial regulatory framework involving xenotransplantation to be laid down by the TGA.(1) In addition, in conjunction with the AHEC and the AWC, the NHMRC has issued guidelines for researchers and ethics committees involved in animal-to-human studies and provisions have been made to establish a patient registry database.

Background on Australian Biological Regulatory Framework

The initial collaboration between the TGA and the NHMRC began in April 2003 when they jointly established a Review of the Australian Arrangements for Clinical Trials and Access to Unapproved Therapeutic Goods.(2) The primary goals of this Review were to:

  • identify any necessary improvements to the current arrangements, thereby maximizing protection of patient and trial participant safety, and maintaining public confidence;
  • assess the need for, and practicability of, a clinical trial register system; and
  • identify any barriers to the further development of clinical research.

As a result of this Review, it became clear that the existing framework was insufficient to address the regulatory classification requirements specific to cell and tissue-derived therapeutic goods. A Biologicals framework was developed from an initial proposal for the regulation of human cells and tissues. The proposal was endorsed by the Australian Health Ministers' Conference (AHMC) in 2002, and the AHMC subsequently approved the Human Cells Tissue (HCT) regulatory framework and its implementation as part of the proposed Australia and New Zealand Therapeutic Products Authority (ANZTPA) in 2006. Although the ANZTPA project was postponed in 2007, it was still agreed that the Biologicals framework would initially advance within Australia alone. To this end, legislation and supporting documents are being drafted with an expected implementation date of 2010 and a transition period to be incorporated into legislation. The legislation addresses human stem cells, however, assisted reproductive tissues, solid organs, blood and blood products are currently not included. Haematopoietic progenitor cells are still also under consideration for inclusion.(3)

The NHMRC and the TGA will be using internationally established guidelines including those developed by the European Medicines Agency and the World Health Organization to ensure harmonization in the management and regulation of their own clinical research framework for xenotransplantation. The TGA is also committed to issuing more guidance documents to ethics committees in order to aid all the stakeholders in assessing the most appropriate route of assessment for clinical trial proposals.
