    NIDDK invites investigator-initiated (R01) research project applications for ancillary studies to ongoing large-scale clinical trials and epidemiological studies (parent studies) and disease databases supported by the Institute, other Institutes and Centers of the National Institutes of Health, other government agencies, or the private sector. Applications for ancillary studies may be submitted to PA-20-185  or other appropriate notices of funding opportunities (NOFOs).
Ancillary study proposals
must extend knowledge of diseases being studied by parent study investigators under a defined protocol or study diseases and conditions outside of the original scope of the parent study but within the research areas and mission of NIDDK
    must abide by the procedures for conducting ancillary studies established by the parent study
    may require additional data or sample collection
    may not interfere with the primary objectives of the parent studyParent Study Examples
Select NIDDK-sponsored parent studies that are eligible for ancillary study proposals are listed below. View each website for study-specific ancillary study procedures.
