The late-breaking abstract submission will open on May 5

The EHA late-breaking abstracts policy allows for the submission of abstracts containing clinical or non-clinical data which were unavailable at the time of the abstract submission deadline (March 1, 2023). For clinical trials, a preplanned analysis of the primary endpoint should have been scheduled after this date. 

Please note that the selected late-breaking abstracts will only be made available on the EHA Library and via the program on the EHA website.

Abstract authors will be informed about the results of the review by May 26, 2023. Should you have any questions regarding any submitted abstracts please contact
