Dear Friends and Colleagues,
This newsletter comes to you at a most exciting time for the field of xenotransplantation, with the world’s gaze upon the recent clinical xenotransplants and to IXA’s role as the guiding professional representative expert association. In the past 6 months, we have seen the realisation of clinical xenotransplantation as a new clinical therapy, a great step forward with several amazing achievements including the first successful pig-to-human xeno-heart transplant.
The link below was recorded by TTS with Muhammed Mohiuddin, Professor of Surgery Director, Program in Cardiac Xenotransplantation, University of Maryland School of Medicine detailing the the Pig Heart Xenotransplant they did in January this year.
For such clinical xenotransplant programs to occur, we need to have underpinning support. We need to acknowledge support from the various international and national government agencies that have been longstanding supporters of the concept of xenotransplantation clinical trials. Agencies such as the World Health Organization (WHO), the USA Food and Drug Administration (FDA), European Medicines Agency (EMA), the Australian Therapeutic Goods Administration (TGA) and the Chinese FDA, that have supported the development of guidelines for these life changing xenotransplants. These breakthroughs also exemplify how hard the IXA have worked with these agencies, the TTS and the WHO in the regulatory sphere to run workshops and develop guidelines to optimize regulations and legislation to make this possible. These successes are the validation for our efforts over the past few decades!
Most recently, the USA FDA held an open Advisory Committee Meeting for the Cellular, Tissue, and Gene Therapies Advisory Committee meeting on June 29-30, 2022 where the main topic was xenotransplantation. There were many groups and institutions represented and that presented at this meeting to support xenotransplantation. The IXA and some of its members provided input to several committees and groups that were invited to present or provide submissions to the FDA committee. These included organisations such as the Juvenile Diabetes Research Foundation (JDRF), the American Society of Transplantation (AST) and American Society of Transplant Surgeons (ASTS) among many other professional organisations that provided great support and provided both written and verbal submissions to the meeting.
In addition, the TTS Ethics Committee commenced the development of a White paper on clinical xenotransplantation, which is being drafted in conjunction with the IXA council and several of the IXA members. Invited members at this point are Drs Ian Dittmer, Richard Pierson, Peter Stock, Wayne Hawthorne, Ivo Kwon, and Muhammed Mohiuddin with Jennifer Groverman providing administrative support from TTS. It was agreed that the aim was to submit a “white” paper discussing the ethical issues around clinical xenotransplantation with the intent to publish in the journals Transplantation or Xenotransplantation. The paper will be aimed at transplanting clinicians who are not specifically involved in xenotransplant research or potential clinical programmes, to provide insight as to what ethics surround the use of xenotransplantation.
The leadership of the AST and ASTS have also consulted with key stakeholders to develop an advisory panel with broad expertise in xenotransplantation, to help provide guidance to help advance xenotransplantation to the clinic. Allan Kirk, together with past presidents of the AST and ASTS, Drs. John Gill and Osama Gaber, have asked several members of the IXA to serve on this new joint advisory panel. Dr. Kirk is Chair of this committee, and this group includes leadership with experience in xenotransplantation; with myself representing the IXA, Jay Fishman (infectious disease), as well as several others also from the IXA council or previous council members (Mohammed Mohiuddin, Joe Tector, Emmanuelle Cozzi, David Cooper, Megan Sykes and David Sachs), industry, and patient participation with ex-officio representation planned from the FDA and NIH as well. The primary objective of the advisory panel is to provide broad insight and knowledge in support of the safe and rational development of clinical xenotransplantation pathways. The panel will also engage with the IXA and TTS to share knowledge with academic discussion and consensus development, participate in the development of guiding principles for ethical and safe transplants, and to help ensure transparency and public trust.
One of the other major highlights of the year is the forthcoming World Congress of the TTS in Buenos Aires, Argentina where there are some wonderful presentations planned, that include several xenotransplant experts and many presentations on xenotransplant programs from our membership. There are multiple parallel session speakers, but I draw your particular attention to the; “Getting ready for clinical xenotransplantation” (State-of-the-Art Session).
I look forward to seeing you all at TTS and joining us at the many wonderful presentations planned for the meeting.
You are all no doubt looking forward to the continuation of a very successful year, as am I, where we may be able to meet in person at one of the various scientific meetings planned for the remainder of the year.
