Both a DCC application and a corresponding CCC application need to be submitted simultaneously for consideration by NCCIH. Trials for which this NOFO applies must be relevant to the research mission of NCCIH and considered a high priority by the Center. For additional information about the mission, strategic vision, and research priorities of NCCIH, applicants are encouraged to consult the NCCIH website (http://www.nccih.nih.gov). Applicants are encouraged to contact the appropriate Scientific/Research contact for the area of science for which they are planning to develop an application prior to submitting to this NOFO. This NOFO requires a Plan for Enhancing Diverse Perspectives (PEDP), which will be assessed as part of the scientific and technical peer review evaluation. Applications that fail to include a PEDP will be considered incomplete and will be withdrawn.Applicants are strongly encouraged to read the NOFO instructions carefully and view the available PEDP guidance material.
