Abstracts submitted during the late-breaking time, January 13 - February 10, 2024, will only be considered if the data analysis were NOT available before the ATC original abstract submission deadline date of December 2, 2023. There are no exceptions.

There will be very limited slots for late-breaking presentations. Please include a brief justification (on the Questionnaire submission page) why this should be considered a "late breaking abstract".

Clinical Trial Abstract Submissions

ATC has incorporated for the second year in a row, a category for Late Breaking Abstracts titled Clinical Trials. This category invites submissions of abstracts describing results of clinical trials in which results become available after the initial abstract deadline and can be presented at the conference.

Important for Late Breaking Clinical Trial Category:
We invite submissions that highlight ongoing trials of importance in transplantation without interim or final results available.
