Early Career Investigator Award Abstracts

Regular Abstracts with primary and presenting authors that are students, postdoctoral research fellows, clinical fellows, or junior faculty with three or fewer years on staff and are current SITC members, may be eligible to receive an Early Career Investigator Award. Early Career Investigator Award Abstracts require a letter of recommendation as well as additional information regarding the percentage of contribution by the primary and presenting author. The time frame to submit a Early Career Investigator Award Abstract to the 41^st  Anniversary Annual Meeting is April 22, 2026 until 5 p.m. PT on June 25, 2026.

Those selected for the Presidential Travel Award will be invited to give an oral abstract presentation during the Presidential Session from 9:05–10:30 a.m. on Sunday, Nov. 8, 2026 (session time subject to change). An abstract submitted for an Early Career Investigator Award that does not receive an award may still be accepted as an abstract for SITC 2026 and will be considered a Regular Abstract.

Late-Breaking Abstracts - Clinical Only (LBA)

Late-breaking Abstract - Clinical Only (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 41^st 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. 10 at 5 p.m. PT.

If a LBA is not accepted, it will not be published or presented at the meeting.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/Early Career Investigator Award Abstract.

LBAs are considered for a limited allocation of oral and poster presentation slots on either Friday, Nov. 6 or Saturday, Nov. 7.
