Opportunity Summary:

The Non-healing Ulcerative Wounds in Aging (R21) funding opportunity (PA 16-231) is a discretionary NIH grant announcement released by the U.S. Department of Health and Human Services (HHS), National Institutes of Health (NIH). It supports exploratory and early-stage research projects using the R21 mechanism, with the overall aim of improving understanding and care of chronic, non-healing ulcerative wounds in the context of aging. The program is centered on the scientific and clinical challenges that make ulcerative wounds persist in older adults, as well as the downstream consequences these wounds have on health, function, and quality of life.

The FOA is open to a wide range of applicants, reflecting NIH's intent to bring together many sectors that can contribute to wound research and translation. Eligible applicants include federal-recognized tribal governments and other tribal organizations, state and local governments (including counties, cities, townships, special districts, and public housing authorities), public and private institutions of higher education, nonprofit organizations with or without 501(c)(3) status, for-profit organizations (including small businesses), and other entities as described in the full eligibility language. In practice, this broad eligibility supports proposals from universities, medical centers, health systems, community-based organizations, research institutes, and industry partners, including those working on diagnostics, therapeutics, devices, and care delivery innovations.

From a research standpoint, the announcement invites applications spanning basic, clinical, and translational approaches, as long as they are clearly tied to non-healing ulcerative wounds in aging or in older persons. Priority areas include (1) studies of the biology, etiology, and pathophysiology of non-healing ulcerative wounds, which may be investigated in animal models and/or directly in older adults; (2) projects that translate findings from basic or clinical research into clinical practice and health decision-making, meaning work that helps move evidence toward real-world use by clinicians, patients, caregivers, and health systems; and (3) research focused on diagnosis, prevention, management, and clinical outcomes of non-healing wounds in older adults, which can include evaluating how wounds are identified, how risk is reduced, how treatment strategies perform, and what outcomes matter most for older patients.

Financially, the opportunity lists an award ceiling of $200,000, aligning with the R21’s role in supporting smaller, innovative projects that generate preliminary data or test new concepts rather than large-scale definitive trials. The activity category is Health, and the CFDA (assistance listing) numbers associated with this opportunity are 93.866 (with the announcement also listing 93.866 again in the source data). The posting and creation dates are May 6, 2016, and the closing date shown is September 7, 2019 (both original and current closing date). While the source excerpt does not specify the exact number of expected awards, the listing indicates that awards were anticipated under the announcement.

Overall, this FOA is designed for investigators proposing well-justified, innovative R21 projects that can advance the science of chronic wound persistence in older populations and help close gaps between mechanistic knowledge, clinical interventions, and practical decision-making. Strong applications under this announcement would typically make a clear connection to aging-related factors that influence wound healing, articulate a plausible pathway from the proposed work to improved prevention or management, and define meaningful clinical or translational outcomes relevant to older adults.

FAQs: Non-healing Ulcerative Wounds in Aging (R21) - PA 16-231

What is the Non-healing Ulcerative Wounds in Aging (R21) funding opportunity?

This is a discretionary NIH grant opportunity (PA 16-231) released by the U.S. Department of Health and Human Services (HHS), National Institutes of Health (NIH). It supports exploratory and early-stage research projects using the R21 mechanism, focused on improving understanding and care of chronic, non-healing ulcerative wounds in the context of aging.

What is the main purpose of this FOA?

The purpose is to advance science and care related to chronic, non-healing ulcerative wounds in older adults. The announcement emphasizes the scientific and clinical challenges that cause ulcerative wounds to persist in older persons, along with the downstream consequences for health, function, and quality of life.

What type of grant mechanism does this opportunity use?

The opportunity uses the NIH R21 mechanism, which is intended for exploratory and early-stage research. Projects are generally positioned to test new concepts or generate preliminary data rather than to run large, definitive trials.

What research topics does the program prioritize?

The FOA invites basic, clinical, and translational research as long as it is clearly tied to non-healing ulcerative wounds in aging or in older persons. Priority areas include:

  • Biology, etiology, and pathophysiology of non-healing ulcerative wounds (in animal models and/or directly in older adults)
  • Translation of findings into clinical practice and health decision-making (moving evidence toward real-world use by clinicians, patients, caregivers, and health systems)
  • Diagnosis, prevention, management, and clinical outcomes in older adults (including identification, risk reduction, treatment performance, and outcomes that matter to older patients)

Is this FOA limited to clinical research, or can it include basic and translational work?

It can include basic, clinical, and translational approaches. The key requirement described is that the project must be clearly connected to non-healing ulcerative wounds in aging or older persons, and aligned with the FOA's stated priority areas.

Does the FOA allow studies using animal models?

Yes. The FOA explicitly notes that studies of the biology, etiology, and pathophysiology of non-healing ulcerative wounds may be investigated in animal models and/or directly in older adults.

Does the FOA encourage projects that support real-world clinical decision-making?

Yes. One of the priority areas is translating findings from basic or clinical research into clinical practice and health decision-making, including work that helps clinicians, patients, caregivers, and health systems use evidence in real-world settings.

What kinds of outcomes are considered relevant under this opportunity?
