Embargo policy

IMPORTANT! Change of abstract embargo date for 2025

Abstracts accepted for the 2025 ESGCT Annual Congress will be made available to Congress registrants on Wednesday 1 October at 11:00am CEST.

Previously ESGCT Congress abstracts have been embargoed until the first day of the Congress. However, due to increasing numbers of abstract submissions in recent years, and in response to requests received and previous delegate feedback, the full text of all abstracts accepted for the 2025 ESGCT Annual Congress will be published in the week before the Congress begins, on Wednesday 1 October. This is to allow Congress delegates more time to browse abstracts and select oral and poster presentations of interest before the Congress begins.

Full text of accepted abstracts will be made available to registrants on Wednesday 1 October 2025 at 11:00am CEST. Researchers and presenters are free to discuss the content of their abstracts throughout this embargo period, but any abstract-related content may not be published until the abstracts are publicly released online.

Updated data, new graphics, and follow-up information to be presented during oral presentation sessions is embargoed until 8:00am CEST on the day of the presentation.

Posters will be made available from the first day of the Congress, therefore all updated data, new graphics, and follow-up information is embargoed until 8:00am CEST on the first day of the Congress.

Upon notification acceptance, ESGCT will publish the abstract titles and presenting authors on the ESGCT Congress website and other communication channels. After an abstract author has accepted their presentation role, the author and their organisation are welcome to publicise the title, author name, and session information across their communication channels, tagging ESGCT where applicable.

Press release guidelines

Public information officers or public relations firms representing academia or industry with abstracts in the Congress can issue press releases according to the schedule below:

A press release that includes the title and logistical presentation details only (presenter, session information, etc.) may be issued once the oral and poster presenters are published on the ESGCT Congress website. These title-only press releases must not include any data or information from the abstract.
A press release that includes full data from a poster or poster abstract may be issued from 08:00am CEST on the first day of the Congress.
For oral presentations: A press release that includes full data from an oral presentation be issued at the beginning of the session where the study will be presented.

Publication exceptions

In exceedingly rare circumstances, ESGCT may grant an exception to the embargo policy in order to comply with regulations from the ESMA or international law.

Any exception request must be submitted to ESGCT in writing to Gaëlle Jamar at least 72 hours before the conclusion of the public embargo, and must include the following:

Statement that an exception is required to abide by applicable securities laws
Statement that the disclosed information is the absolute minimum necessary to comply with the applicable securities law
The lead author and presenter (both if they are different) copied on any correspondence
Signature of legal counsel

Whenever possible, ESGCT prefers any disclosure to follow these guidelines:

Do not include implications or translational interpretations of results
Necessary data presented in qualitative terms rather than quantitative terms
Include the submission to and upcoming presentation at the ESGCT congress

For example, a press release stating “the research which will be presented at the ESGCT conference will bring gene therapy for [insert disease] closer to the clinic, and we are looking forward to giving you more details during our presentation,” is a qualitative statement and preferred in the case of an exception. However, a statement such as “in the study submitted to ESGCT, 5 of 7 patients demonstrate no disease symptoms and we’ve applied for EMA fast track designation,” is a quantitative statement and should not be included in a release.
