Late-breaking abstract submission

Late-breaking abstract procedure

The official late-breaking abstract submission will be open from May 7-12, 2021 (23:59 CEST). The full late-breaking abstract submission terms & conditions can be found here.

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, 2021). For clinical trials, a preplanned analysis of the primary endpoint should have been scheduled after this date. 

Please note that due to the late scheduling of the procedure the selected late-breaking abstracts will be made available in the online version of the Abstract Book (supplement of HemaSphere, the official EHA Journal), the EHA Library (previously known as EHA Learning Center,) and via the program on the EHA website.

Abstract authors will be informed about the results of the review by May 26, 2021. Should you have any questions regarding any submitted abstracts please contact
