How many LOIs am I permitted to submit to this PFA?

Applicants may submit multiple Letters of Intent within the same PCORI Funding Announcement (PFA) or across multiple PFAs provided the proposed LOIs do not exhibit significant scientific overlap. Moreover, an individual listed as a PI on one LOI may be listed as and serve in another role (e.g., co-investigator, or consultant) on other LOIs within the same PFA during the same cycle. If a PI submits multiple LOIs under the Migraine Prevention PFA or to other PFAs offered within a given cycle, LOIs that exhibit scientific overlap or that appear to be duplicate submissions will be disqualified. PCORI will contact the PI to choose which LOI should advance to review.  The restriction on overlapping or duplicate submissions applies to single- and dual-PI submissions.
