Non Invasive Methods for Diagnosis and Progression of Diabetes, Kidney, Urological, Hematological and Digestive Diseases (R01) | Apply Online

Opportunity Summary:

The NIH National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) is soliciting Research Project Grant (R01) applications under the funding opportunity titled "Non Invasive Methods for Diagnosis and Progression of Diabetes, Kidney, Urological, Hematological and Digestive Diseases (R01)" (Funding Opportunity Number PA-07-025). The central aim is to push forward imaging and other non-invasive or minimally invasive technologies that can be used in people to detect and characterize disease, improve diagnosis, identify individuals at elevated risk or with a predisposition to disease, and monitor responses to treatment over time. A major theme is enabling better ways to study both normal and diseased tissues in vivo, meaning directly in living systems, rather than relying on invasive biopsies or indirect measures that may miss early or subtle changes.

Scientifically, the FOA emphasizes the development and application of advanced approaches that can capture meaningful biological signals related to disease onset and progression. NIDDK is particularly interested in technologies that produce robust surrogate markers that could serve as clinical trial endpoints, which is a practical need in many chronic diseases where definitive outcomes may take years to develop. In other words, the program is looking for measurable indicators that can reliably reflect whether a disease is getting better or worse, or whether a treatment is working, without requiring long follow-up periods or highly invasive testing. Alongside surrogate markers, the FOA encourages methods that improve the resolution and specificity of tissue characterization, including the ability to distinguish normal physiology from early pathology.

The diseases and conditions within scope are broad but unified by NIDDKs mission areas. These include type 1 diabetes and type 2 diabetes, obesity, and a wide range of kidney, liver, urologic, hematologic, digestive, endocrine, and metabolic diseases, as well as their complications. The opportunity is therefore relevant to investigators working across multiple organ systems, especially where current clinical tools are limited by invasiveness, lack of sensitivity to early disease, or inability to track dynamic physiological processes in real time.

On the technology side, NIDDK highlights molecular imaging and functional imaging as especially relevant, along with imaging methods that provide high spatial resolution, high chemical resolution, or high time resolution. The FOA also calls out newer spectroscopic approaches and sensor array technologies aimed at monitoring metabolic or physiological events, which can include techniques designed to measure biochemical changes, tissue composition, perfusion, oxygenation, metabolism, or other functional properties that shift as disease develops or responds to therapy. The common denominator is that these approaches should reduce patient burden compared with traditional invasive diagnostics while producing clinically meaningful information that can support diagnosis, prognosis, risk stratification, or treatment monitoring.

In terms of funding mechanism and structure, this program uses the NIH R01 mechanism, which is intended for more mature, hypothesis-driven or well-justified research projects that typically involve substantial development, validation, and application. The FOA notes that it runs in parallel with an opportunity of the same scientific scope that uses the R21 exploratory/developmental mechanism (PA-06-142), which signals that NIDDK is supporting both earlier-stage, higher-risk concept development (R21) and more fully developed projects positioned for broader validation and impact (R01).

Budget size, project duration, and the number of awards are not fixed because NIDDK expects applications to vary widely in scope and cost depending on the disease target, technology platform, and level of validation proposed. As a result, the total funding and award count will ultimately depend on the number of applications received, their scientific quality, the requested durations, and the proposed costs.

Eligibility is broad and includes many types of domestic organizations such as state and local governments, tribal governments and tribal organizations, public and private institutions of higher education, nonprofits (with and without 501(c)(3) status), for-profit organizations (including small businesses), independent school districts, and special district governments. Importantly, the announcement specifies that foreign institutions are eligible to apply, and eligible federal agencies may also apply. Faith-based and community-based organizations are also permitted, expanding the potential applicant pool beyond traditional academic medical centers.

Administratively, this is a discretionary grant opportunity listed under CFDA 93.847 (Diabetes, Digestive, and Kidney Diseases Extramural Research), with no cost sharing or matching requirement. It was posted on November 20, 2006, and uses multiple receipt dates rather than a single deadline, meaning applicants must refer to the full announcement for the applicable submission cycles and due dates. The full FOA is linked through the NIH Grants Guide at http://grants.nih.gov/grants/guide/pa-files/PA-07-025.html, and the NIH Office of Extramural Research (OER) webmaster contacts are provided for access or linking issues.
