PA-20-163: Competing Revisions to Existing NIH Grants and Cooperative Agreements (Clinical Trial Optional)

Issued by
National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK)


This Notice of Special Interest invites competitive revision applications to support the expansion of existing NIDDK-funded R01, U01, U24, U54, and P30 awards to address the increasing burden of chronic diseases and to reduce health disparities in the development, diagnosis, and treatment of diseases of high priority to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).


NIDDK’s research interests include chronic diseases and conditions such as diabetes and other endocrine and metabolic diseases; digestive diseases, nutritional disorders, and obesity; and kidney, urologic, and hematologic diseases. Many of these diseases and disorders disproportionately affect the health of under-served populations in the United States. It is recognized that both biologic and non-biologic factors may contribute to the development or progression of diseases of interest to NIDDK for these under-served populations. For the purposes of this FOA, health disparities is defined according to Healthy People 2020 as a particular type of health difference that is closely linked with social, economic, and/or environmental disadvantage. Health disparities adversely affect groups of people who have systematically experienced greater obstacles to health based on their racial or ethnic group; religion; socioeconomic status; gender; age; mental health; cognitive, sensory, or physical disability; sexual orientation or gender identity; geographic location; or other characteristics historically linked to discrimination or exclusion.

Research Objectives

Research approaches relevant for this opportunity may include, but are not limited to metabolic, genetic, genomic, proteomic, behavioral, clinical and/or epidemiologic research in representative populations, including differences across the lifespan. NIDDK particularly encourages projects which create multidisciplinary regional collaborations across areas with high prevalence of health disparities and chronic diseases, such as the southeastern United States.

Collaboration among investigators of extant cohort studies that have been established for investigation of diseases or conditions within NIDDK’s mission would be desirable, so that these studies might jointly develop protocols and evaluate findings. Clinical trials seeking to prevent, mitigate, or treat diseases or conditions within NIDDK’s mission would be appropriate.

Applicants for competitive revision awards are encouraged to form new collaborations between scientists working at different centers and scientists with expertise in varying disciplines. Applications from institutions with a strong existing track record of NIH funding in related areas, such as an NIH-funded Nutrition Obesity Research Center, Center for Diabetes Translation Research, Diabetes Research Center, Nutrition Obesity Research Center, and O'Brien Kidney Center are encouraged.

Potential Research Areas

Appropriate topics for investigation in NIDDK diseases and conditions include, but are not limited to:

  • Strategies to improve the identification of NIDDK-specific diseases or disorders that may facilitate or accelerate early intervention, particularly in populations which bear a disproportionate burden of disease;
  • Strategies to address social needs and stressors (lack of access to quality food or housing, transportation needs) in healthcare contexts that may include partnerships with community resource organizations/entities with expertise to address social determinants of risk;
  • Strategies to slow progression of diseases and disorders in NIDDK’s mission and reduce risk factors for the development of complications, such as but not limited to kidney diseases, liver diseases, gastrointestinal diseases, retinopathy, genitourinary diseases and disorders, neuropathy, cardiometabolic disease, malnutrition, frailty and/or sarcopenia, metabolic bone disease, and depression, especially in populations with increased risk for disease progression and complications;
  • Innovative approaches to promote the adoption and maintenance of individual-level behaviors shown to improve outcomes, including, but not limited to dietary intake, physical activity and sedentary behavior, risk factor management, mental health management, and medication and/or treatment adherence;
  • Strategies to improve utilization of kidney transplantation and home dialysis in populations with decreased utilization of these modalities;
  • Studies designed to better understand racial and ethnic differences in screening, diagnosis, incidence, and prevalence of NIDDK diseases and whether there are differences among sub-groups in the rates of progression; with an emphasis on identifying factors that help inform treatment development, practice, or policy designed to reduce or eliminate disparities;
  • Strategies to overcome health care system barriers that reduce the efficiency or effectiveness of patient/provider interactions, reduce barriers to access and improve patient health literacy, education, and treatment adherence, and/or improve implementation of care, which then lead to better health outcomes;
  • Rigorous mixed-method approaches to understand facilitators and barriers to research participant engagement (e.g., initializing and sustaining engagement, recruitment/retention);
  • Strategies to increase recruitment of participants from high-burden communities above/beyond targeted enrollment in research studies and strategies to improve retention;
  • Strategies to improve the science of or activities that promote stakeholder-driven research to include guidance to existing projects or the development of future research activities (e.g., grant proposals), including stakeholder-informed research questions and proposed activities to address the questions and improve uptake of recommendations from research discoveries;
  • State-of-the-art, hypothesis-driven mechanistic studies to determine whether there are biological differences that might influence disease development, progression and/or outcomes across populations;
  • Basic science studies for health disparities, where scientifically appropriate.

Research with animal models would not be appropriate for the purposes of this funding opportunity. Clinical trials are allowed, but this NOSI will not support new multi-center clinical studies. A study is considered to be "multi-center" if three or more sites are involved in the actual conduct of the study. A clinical study will not be considered to involve multiple centers if participant recruitment occurs at three or more locations, but all interventions and/or outcomes assessments are performed by a single study team.
