Opportunity Summary:

This funding opportunity (RFA DK 12-509) is a National Institutes of Health (NIH) cooperative agreement (U01) that offers a limited competition to support the continuation and extension of the ASSESS AKI consortium study. The core goal is to keep an existing, well-characterized observational cohort running long enough to generate statistically solid, clinically meaningful findings about what happens to patients after an episode of acute kidney injury (AKI). Rather than launching a new trial, the announcement is focused on extending ongoing consortium activities so that longer-term follow-up data can be collected and analyzed, strengthening the power and credibility of outcome estimates.

The scientific purpose of the extension is to track and compare long-term outcomes in several groups: patients who had an AKI episode and previously had normal kidney function, patients who had an AKI episode in the setting of chronic kidney disease (CKD), and appropriate control participants who did not experience AKI. The study is designed to determine how AKI influences multiple downstream outcomes over time, including (a) long-term kidney functional outcomes (such as progression to CKD, worsening CKD, or other measures of declining renal function), (b) long-term cardiovascular disease outcomes (recognizing the close relationship between kidney injury and cardiovascular risk), (c) patient-centered outcomes such as quality of life and cognitive functioning, and (d) survival. By extending follow-up, the consortium can better capture events that occur months to years after AKI and can more reliably quantify risk trajectories, not just short-term complications.

A major additional emphasis is biomarker evaluation. The announcement highlights assessing the usefulness of putative biomarkers for predicting both short- and long-term outcomes after AKI. In practical terms, this means the consortium intends to determine whether biological signals measured around the time of injury and during follow-up can help forecast who will recover, who will progress to chronic impairment, who may face cardiovascular complications, and who is at higher risk for mortality or functional decline. This biomarker component is important because it can move the field beyond relying only on traditional clinical measures (like serum creatinine) and toward earlier or more accurate risk stratification tools.

From an organizational standpoint, ASSESS AKI is structured as a consortium, consisting of three Participating Clinical Centers (PCCs) and a Data Coordinating Center. This arrangement supports standardized data collection, coordinated follow-up, centralized data management, and consistent analytic approaches across sites. The opportunity notes that an additional site was added as an ancillary study in 2010, indicating that the consortium has already expanded its reach and likely has established infrastructure for integrating multi-site data and ancillary efforts.

Administratively, the opportunity falls under the NIH funding activity category listed as health (with the CFDA number 93.847, associated with Diabetes, Digestive, and Kidney Diseases Extramural Research), and it uses a cooperative agreement mechanism, which generally implies substantial NIH programmatic involvement compared with a standard grant. The announcement was posted on August 30, 2012, with a single closing date of November 21, 2012, and an archive date of December 22, 2012. The estimated total funding amount is $2,200,000, and the announcement explicitly states there is no cost-sharing or matching requirement.

Eligibility is restricted, consistent with the phrase "limited competition." While the posting indicates "Others (see text field entitled Additional Information on Eligibility for clarification)," it clearly excludes non-U.S. (foreign) institutions from applying, excludes non-U.S. components of U.S. organizations, and disallows foreign components as defined by the NIH Grants Policy Statement. In other words, the competition is intended for eligible domestic entities, and, given the nature of a continuation for an established consortium, it is typically aimed at the existing participating sites or otherwise narrowly defined eligible applicants connected to the ongoing ASSESS AKI effort.

Overall, this opportunity is essentially about protecting the value of an already-built cohort and research platform by funding continued follow-up and coordinated analyses. The extension is framed as necessary to ensure statistical power and the significance of the study outcomes, reflecting the reality that long-term endpoints like CKD progression, cardiovascular events, cognitive changes, and mortality require time and adequate sample sizes to evaluate properly. For full details, NIH directed applicants to the complete announcement at the provided NIH Grants Guide link, and technical access issues were routed to the NIH Office of Extramural Research (OER) webmaster contacts.

Frequently Asked Questions (FAQs) - RFA DK 12-509 (ASSESS AKI Consortium Extension, U01)

What is RFA DK 12-509?

RFA DK 12-509 is a National Institutes of Health (NIH) funding opportunity that uses a cooperative agreement mechanism (U01) to support the continuation and extension of the ASSESS AKI consortium study. It is described as a limited competition and is focused on extending an existing observational cohort rather than starting a new study.

What is the main purpose of this funding opportunity?

The main purpose is to keep an existing, well-characterized observational cohort active long enough to generate statistically strong and clinically meaningful results about what happens to patients after an episode of acute kidney injury (AKI). The extension is intended to enable longer-term follow-up, analysis, and stronger outcome estimates.

Is this opportunity meant to launch a new clinical trial?

No. The announcement emphasizes continuation and extension of ongoing consortium activities and follow-up, not the launch of a new trial.

What type of study is being supported?

The funding supports an established observational cohort within the ASSESS AKI consortium, with continued follow-up and coordinated analyses across participating sites.

Why is extended follow-up important for this project?

Extended follow-up helps capture events that occur months to years after AKI and improves the ability to quantify long-term risk trajectories. Outcomes such as chronic kidney disease (CKD) progression, cardiovascular events, cognitive changes, quality of life impacts, and mortality often require longer time horizons and adequate sample sizes to evaluate reliably.

Which participant groups are being tracked and compared?

The extension is designed to track and compare long-term outcomes across several groups: (1) patients who experienced AKI and previously had normal kidney function, (2) patients who experienced AKI in the setting of chronic kidney disease (CKD), and (3) appropriate control participants who did not experience AKI.

What long-term kidney outcomes are of interest?

The study aims to evaluate long-term kidney functional outcomes, including progression to CKD, worsening CKD, and other measures reflecting declining renal function over time.

What cardiovascular outcomes are of interest?

The study includes long-term cardiovascular disease outcomes, reflecting the close relationship between kidney injury and cardiovascular risk.

What patient-centered outcomes are included?

The extension includes patient-centered outcomes such as quality of life and cognitive functioning.

Is survival measured as part of the study?

Yes. Survival is explicitly listed as one of the outcomes the consortium is designed to evaluate over long-term follow-up.

What role do biomarkers play in this funding opportunity?

A major additional emphasis is biomarker evaluation. The consortium is expected to assess the usefulness of putative biomarkers for predicting both short- and long-term outcomes after AKI.

What is the biomarker evaluation intended to predict?

Based on the announcement description, biomarker evaluation is intended to help forecast outcomes such as recovery versus progression to chronic impairment, cardiovascular complications, mortality risk, and functional decline.

Why is biomarker work highlighted in this extension?
