NEW: Late-Breaking Abstract Submission Open to All

To accommodate for the unfortunate impact COVID-19 has had on the progress of cancer immunotherapy research this year, SITC leadership has decided to open the late-breaking abstract (LBA) submission period to everyone. SITC will not require an LBA application to be submitted beforehand.

Everyone who has already submitted an LBA application will automatically be invited to submit a full LBA during the LBA submission period, Sept. 8-22, 2020, at 5 p.m. PDT.

The LBA criteria will be altered to accommodate all research regardless of whether the data was ready for submission during the regular submission period or not. We hope this additional opportunity for abstract submission will provide a little assistance for all of the incredibly important work you are doing to continue moving the cancer immunotherapy field forward during this remarkably unusual year. 

Submissions are now open.

Late-Breaking Abstract

Recognizing the unfortunate impact COVID-19 has had on the progress of cancer immunotherapy research this year, SITC leadership has opened the late-breaking abstract (LBA) submission period to all submitters.

SITC will no longer require a LBA application to be submitted beforehand. If you have previously submitted a LBA application, you will automatically be invited to submit a full LBA during the submission period, Sept. 8–22, 2020.
