American Society of Hematology

Annual Meeting Embargo Policy

The media as well as corporations and institutions issuing press releases are required to abide by the embargo policies governing the Society's annual meeting.

The information contained in the abstracts is embargoed until the abstracts are available online. The abstracts selected for plenary, oral, and poster presentations will be posted online on November 1 at 9 a.m. Eastern Time in compliance with the Securities and Exchange Commission's Regulation FD. At that time, the embargo will lift on the data included in the abstract, including the abstract title, presentation time and date, and study authors.

Information that goes beyond that which is contained in the four corners of the abstract (e.g., additional analysis, commentary, or updated information from those individuals and companies involved in the study) is embargoed according to the following criteria:

  • For oral presentations: The embargo time is the start time of the session in which the presentation is being made, or the beginning of the ASH press briefing containing the research, whichever comes first.
  • For poster presentations: The embargo lifts when the poster session containing the poster opens for viewing in the morning (i.e., when the poster hall opens that day), or at the beginning of the ASH press briefing containing the research, whichever comes first.
  • For online-only abstracts: The embargo lifts when the abstract is first made publicly available online the week of the annual meeting. These abstracts are not presented at the annual meeting.

Exception to Embargo Policy - SEC Regulations

In certain situations, a publicly traded company may be advised by legal counsel that certain data from the abstract must be disclosed to the public prior to the public release of the abstracts in order to comply with requirements of the U.S. Securities and Exchange Commission (SEC) or a corresponding regulatory body in the country where the company's stock is traded. Under such extenuating circumstances, ASH may grant an exception to its embargo rules and allow the company to release limited top line-data (i.e., general findings with no additional analysis, commentary, investigator quotes, etc.) from the abstract without jeopardizing its eligibility for presentation at the annual meeting.

In order to request an exception to the ASH embargo policy for an accepted abstract, the following should be sent to ASH Communications Specialist Stephen Fitzmaurice at sfitzmaurice@hematology.org with a copy to the corresponding author of the abstract:

  1. detailed information about the release, including the nature of the data to be included and timing of the release; and
  2. a letter signed by legal counsel (see sample letter) advising that disclosure of the information is necessary to comply with applicable securities laws and that the information contained within is only the minimum necessary to ensure such compliance.

If the request is being made before the abstract has been accepted, the above information must be emailed to ashabstracts@hematology.org and Stephen Fitzmaurice should be copied.

The press release (see sample press release) should note that the abstract has been submitted (or accepted, if appropriate) for presentation at the ASH annual meeting. ASH will evaluate these requests on a case-by-case basis and reserves the right to change the type of presentation (e.g., from oral to poster) or remove the abstract from the annual meeting program if the released information is judged to substantially detract from the novelty of the annual meeting presentation.
