Regular, Young Investigator Award (YIA), and Immune Engineering Abstracts: the submission period is April 24, 2024, through June 27, 2024, at 5 p.m. PDT.

Late-breaking Abstracts - Clinical Only (LBAs): the submission period is July 15, 2024, through Sept. 12 , 2024, at 5 p.m. PDT.

There is no limit to the number of authors that can be included on an abstract. All authors must have at least one institution listed, and there must be a minimum of one corresponding, one primary and one presenting author for each abstract.

Once an abstract is submitted, the presenting author is automatically sent an email notification asking them to complete their Conflict of Interest (COI). The email notification contains a link that takes to the online COI form. They will need to log in to their SITC Connect account to access the form. Should the presenting author have any issues with the online COI form, they can reach out to education@sitcancer.org. The submitting author can check if the presenting author has submitted their COI by reaching out to SITC staff at education@sitcancer.org. 

There is no limit to the number of tables, figures or images that can be included on an abstract. All figures, tables and images must be numbered (i.e.: Table 1, Figure 1, or Image 1) in the title field and cited in the abstract text.

Overview & Criteria
SITC understands the crucial need for collaboration and discussion surrounding clinical trials in progress. This abstract submission category aims to allow for open dialogue surrounding such trials and hopes to foster a unique environment in which to discuss the research that is being done.
All phases of clinical research may be considered for inclusion in the Clinical Trials in Progress abstract submission.
Although there are no absolute criteria for abstracts submitted under this category, SITC provide the following general guidelines for your consideration as you prepare your abstract submission for this category.
All abstracts submitted under this category, as for all abstracts submitted in any category, are subject to peer review and possible rejection from being included as an oral and/or poster presentation in the 39^th Annual Meeting & Pre-Conference Programs (SITC 2024).

Submission Guidelines

• Background
• Scientific background/rationale for the trial should be included
• Preclinical and/or earlier-phase clinical data that has already been publicly presented or published may be included with references
• Abstracts should be written/designated with respect to the correlates and hypothesis being tested in clinical trials
• Methods
• Clinical trial registry number (required, if appropriate)
• Trial design and statistical methods (include)
• Treatment or intervention planned (include)
• Major eligibility criteria, highlighting unusual aspects (include)
• It is not a requirement that the trial be recruiting (current status of “Open but Not Yet Recruiting” is acceptable)

NOT acceptable in a Clinical Trial in Progress abstract:

• Completed trials (these should be submitted in other categories)
• Brand or proprietary drug names

Unfortunately, SITC does not accept any Regular, Young Investigator Award (YIA), or Immune Engineering Abstracts after June 27, 2024 at 5 p.m. PDT and does not accept any LBAs after Sept. 12, 2024 at 5 p.m. PDT.

Late-Breaking Abstracts - Clinical Only (LBA)
LBA submission is solely for abstracts with late-breaking data from interventional clinical trials in humans and not for abstracts submitted “late.” The LBA deadline is not intended to be an extension of the general submission deadline. LBAs highlight novel and practice-changing in-human clinical studies, and only apply to data that would have not otherwise have been presented as an abstract at the 39^th Annual Meeting. 

Authors of LBAs do not need to submit an application or a place-holder abstract. LBAs should be submitted during the LBA submission period, from July 15–Sept. 12 at 5 p.m. PDT.

If a Late-breaking Abstract is not accepted, it will not be published or presented at the meeting. There is no longer an option for it to be considered as a Regular/YIA Abstract.

For all questions regarding abstracts please contact education@sitcancer.org.

Regular, Young Investigator Award (YIA) and Immune Engineering Abstracts will be notified if their abstract was accepted for presentation on Aug. 2, 2024. LBA notifications will be sent on Sept. 25, 2024.

Unfortunately, SITC does not offer free registration to abstract presenters.

After Regular, Young Investigator Award and Late-breaking Abstracts are reviewed and selected, abstract submitters are sent an email notification stating whether the abstract was accepted, and, if so, what type of abstract presentation it was accepted as. Within the notification, the abstract submitter will also be asked to accept or decline participation in SITC 2024. If SITC does not receive a response by the stated deadline, SITC will assume you agree to present and will include your abstract.

In addition to oral abstract presentations, oral presenters are invited to present their abstract as a poster and an ePoster as well. ePosters can be uploaded by the presenting author (more information provided in the Speaker Management System). 

Once assigned, abstract numbers cannot be changed.

You may view your submitted abstract by logging into the abstract submission system and clicking on 'Abstract Submissions'.

The deadline for Regular Abstract and Young Investigator Award Abstract withdrawal is Aug. 9, 2024. The deadline for Late-breaking Abstract withdrawal is Sept. 30, 2024. If you would like to withdraw your abstract between the submission deadline and this date, you must submit your request in writing to education@sitcancer.org. Upon receipt of your request SITC will make the change and send a confirmation once the withdrawal has been completed.

Yes, the presenting author must register for the Annual Meeting to present an abstract. Submitting an abstract does not register you for the meeting. All presenting authors are responsible for registering themselves, and booking their own housing, if needed.

Both oral and poster abstract presenters will be informed of their presentation details in their notification email sent on Aug. 2, 2024 for Regular and Young Investigator Award Abstracts and Sept. 25, 2024 for Late-breaking Abstracts.

The abstract number refers to the number assigned to the abstract by SITC, which will be provided in the abstract notification email. The abstract number is the number that is made public for your abstract. The abstract ID is what is assigned by the submission site when you submit your abstract. This number is used for administrative purposes and is not made public.

The abstract number determines where your abstract will be listed in all publications including the Journal for ImmunoTherapy of Cancer (JITC) Supplement, and on the SITC 2024 website and meeting app. For abstracts selected for poster presentation, it also determines where your poster will be located in the Poster Hall.

The abstract number is determined by the category selected when the abstract is submitted and the last name of the primary author.

Before the Submission Deadline: To withdraw or remove your abstract, you will need to begin by logging into the abstract submission system and clicking on 'Abstract Submissions'. Open the abstract you would like to withdraw by clicking on the title. Once you are in the abstract, click on the menu icon in the upper left, next to the Abstract Submission header.
