AACR Annual Meeting Embargo Policy

Last updated March 8, 2021

The AACR Annual Meeting 2021 will be held virtually in two parts: April 10-15 and May 17-21. Abstracts will be made available in two batches prior to the start of the April sessions. Meeting abstracts, presentations, and posters are subject to the embargo policy as outlined below.

Please read the following information closely. You may contact Julia Gunther at [email protected] with additional questions about the AACR’s embargo policy.

IMPORTANT DATES AND TIMES

The embargo lifts on information within the “four walls” of an abstract at the date and time the abstract is posted to the AACR Annual Meeting online itinerary planner:

  • Regular abstract titles, authors, and text will be posted to the online itinerary planner on March 10, 2021 at 4:30 p.m. ET. Press releases including information in the abstract only may be issued at this time.
  • Late-breaking and clinical trial abstract titles and authors ONLY (no text) will be posted to the online itinerary planner on March 10, 2021 at 4:30 p.m. ET. Curtain raiser press releases conveying the abstract title, author, and presentation details (session, date, time, etc.) may be issued at this time but may not include any data.
  • Late-breaking and clinical trial abstract text will be posted to the online itinerary planner on April 9, 2021 at 12:01 a.m. ET. Press releases including information in the abstract only may be issued at this time.

Please refer to the section below for information related to abstracts in the official AACR Annual Meeting Press Program.

AACR Annual Meeting presentations sometimes feature additional or updated information that is not included in the abstracts. In those situations, the embargo will lift on the full data set at the beginning of the session where the study is presented. For posters, the embargo on the full data set/poster will lift on April 10, 2021 at 8:30 a.m. ET, when posters are made available to all meeting attendees.

AACR Annual Meeting Press Program

Studies selected for the official AACR Annual Meeting Press Program are embargoed until April 10, 2021 at 8:30 a.m. ET. At that time, press program abstract text will be posted to the online itinerary planner and the embargo will lift on the full data set for each study.

Public relations professionals and PIOs whose clients or institutions are selected for the press program should contact Julia Gunther at [email protected] to coordinate any outreach plans.

Embargo Violations: Presenters and Public Relations

Presenters, their companies/institutions, and affiliated public relations representatives who break the AACR’s embargo policy as outlined above could jeopardize an abstract’s placement in the scientific program and press events.

Embargo Violations: Media

Individuals registered as press for the AACR Annual Meeting 2021 agree to abide by all embargoes. In advance of the meeting, the AACR will provide abstracts, press releases, and other materials under embargo to registered journalists to facilitate accurate and comprehensive reporting. Failure to abide by the AACR’s embargoes may result in removal from AACR pre-embargo press lists and dismissal from current and future AACR meetings.
