Trials in Progress Abstract Submission Guidelines 
The Trials in Progress category provides a unique opportunity for members of the research community to present ongoing trials and discuss correlatives and novel trial designs with colleagues.

Any phase (I, II, or III) trial that is ongoing and has not yet reached prespecified endpoints for analysis may be considered for inclusion in the Trials in Progress submission category. As such, inclusion of results would be improper and is strictly forbidden.

All submissions will be reviewed for appropriateness by the AACR Annual Meeting Clinical Trials Committee. Accepted submissions will be presented in the Trials in Progress Poster Session.

Abstracts should include Background and Methods only:


  • Scientific background/rationale for the trial
  • Correlative studies of particular interest


  • Trial design and statistical methods, highlighting any novel aspects of the design
  • Treatment or intervention planned
  • Major eligibility criteria, highlighting unusual aspects
  • Clinical trial registry number (required)
  • Trial should be open as of January 12, 2017; however, it is not required that the trial be recruiting (current status of “Open but Not Yet Recruiting” is acceptable)
  • Current enrollment without providing results or endpoints; for example:
    • Enrollment of next cohort began in January 2017; no DLT were observed in either prior cohort.
    • 10% of planned patients have been enrolled as of January 2017 or initial accrual goal was met; second stage accrual began in January 2017.
    • The trial is continuing as planned; the next data analysis will occur on XX date.

What is not acceptable in a Trials in Progress abstract?

  • It is improper and forbidden to include results or preliminary data; any abstracts that include such information will be rejected.
  • Proprietary drug names.

Encore Abstract Submission Guidelines 
The AACR Annual Meeting 2017 will be accepting encore clinical trials presentations, including trials in progress (TiP). Authors must supply information regarding the original presentation, indicating the name of the meeting and publication number at the time of submission. The first author will be responsible for obtaining, and, upon request, showing proof that written permission has been obtained from the copyright holder of the original abstract publication(s). Encore TiP abstract submissions will be accepted for poster presentation only.

Encore submissions must:

  • Have been presented solely in abstract form, including publication in conference proceedings.
  • Include significant additional data from the previous presentation (as determined by the review committee).
  • For TiP, continue to meet the necessary criteria.
