Late-breaking abstracts

Late-breaking abstracts may be submitted for high quality, new research findings from randomised phase II or phase III trials with implications for clinical practice or understanding of disease processes.

Only abstracts for which no conclusive data are available at the time of the abstract submission deadline of 26 September 2023 will be considered for late-breaking status.

Trial in Progress abstracts

Trial in Progress (TiP) abstracts in all phases of clinical research (phases I to III) may be submitted to the ESMO Immuno-Oncology Congress 2023.

It is expected that abstracts submitted as Trial in Progress are ongoing trials that have not reached any protocol-specified endpoints for analysis.

Presentation and publication of accepted abstracts

The ESMO Immuno-Oncology Congress 2023 Scientific Committee will select abstracts for presentation during the Congress based on the following possibilities:

• Proffered Paper – Oral presentations by authors presenting original data of superior quality, followed by expert discussion and perspectives.
• Mini Oral – Short oral presentations by authors presenting data of good quality, followed by expert discussion and perspectives.
• Poster – Display session for review, discussion and questions. The presenting authors must be available for Q&A to represent their work.

All accepted abstracts, including late-breaking abstracts, will be published online only in the ESMO Immuno-Oncology Congress 2023 Abstract Book, a supplement to the official ESMO journal, Immuno-Oncology and Technology (IOTECH).

Publication schedule for accepted abstracts
