Dear colleagues,
The congress of the International Xenotransplantation Association (IXA) ended on Friday in Geneva, Switzerland, and was a resounding success. As the President of the Association at that time, I was humbled by the extraordinary attendance from start to finish. This enthusiasm was achieved through the high quality of xenotransplantation work, even unpublished, that was openly shared by leaders in the field for the benefit of clinical translation of this life-saving option of xenotransplantation. The participation of 21 countries in this meeting demonstrated renewed interest in xenotransplantation, fueled by the granting of permissions for clinical trials. I am grateful to the local organizing committee, led by Leo Buhler and the TTS staff, who worked tirelessly to make this congress a huge success. I am confident that the lessons learned from this meeting will be effectively applied to advance the field further. Thanks again to the membership for making it possible. As I welcome our new president, Jay Fishman, and the council, I hope IXA will continue to provide leadership in this field by developing guidance for investigators and for regulatory agencies worldwide. As we drafted the slogan for this meeting, “We only speak Xeno,” IXA will continue to lead the xenotransplantation field in making it a viable and affordable option for overcoming the worldwide organ shortage.

Welcome Message
Dear colleagues,
We are delighted to invite you to participate in the 18th Congress of the International Xenotransplantation Association, taking place in the cosmopolitan city of Geneva, Switzerland, from September 30 to October 3, 2025. This prestigious event is expected to attract several hundred participants, including leading experts, researchers, and clinicians from around the world who are at the forefront of xenotransplantation science.
After decades of intense pre-clinical research, several clinical organ xenotransplants have been performed in the USA and China over the last two years, indicating that this approach has reached the level of clinical testing. Continuous improvements will be necessary to allow broader applications.
Geneva, known for its rich history and stunning landscapes, provides the perfect backdrop for a congress dedicated to groundbreaking research and innovative clinical trials in xenotransplantation. Attendees will have the unique opportunity to engage with renowned professionals and gain insights into the latest advancements and future directions of the field.
We are committed to creating an enriching and impactful experience for all participants. Join us in Geneva for an inspiring and memorable event that will shape the future of xenotransplantation.
We look forward to welcoming you and working together to advance the field.
Warm regards,
Muhammad Mansoor Mohiuddin
