The intent of the FY23 ERP LRA is to leverage ongoing or completed research studies for which PTE was not an original focus and to provide support to expand the research to develop such a focus and increase our understanding of PTE. The project may include basic, translational, and/or clinical research studies. The study must be associated with an ongoing or completed research effort in which PTE is/was not a research priority and for which addition of cohorts, outcomes, assessments, or analysis specific to PTE would be scientifically justified to increase our understanding of PTE.
