Opportunity Summary:

The National Institutes of Health (NIH) funding opportunity PA-06-405, titled "Studies of Energy Balance and Cancer in Humans (R21)," supports exploratory and developmental research that looks closely at how energy balance relates to cancer. In this context, "energy balance" generally refers to the interplay among factors like diet, physical activity, body weight and body composition, metabolism, and related behaviors or physiological processes that determine energy intake and expenditure. The central goal of this opportunity is to improve understanding of which energy balance-related factors matter most and what biological or behavioral mechanisms connect those factors to cancer risk (whether someone develops cancer), prognosis (how cancer progresses and outcomes after diagnosis), and quality of life (how patients feel and function during and after treatment).

This announcement is specifically geared toward human-focused research and encourages projects that can quickly test ideas, generate preliminary evidence, or open up new directions that could later be expanded into larger studies. It allows a broad range of study approaches, including new analyses of existing datasets (for example, reanalyzing cohort, clinical, or population datasets to explore new hypotheses about obesity, exercise, diet patterns, or metabolic markers) as well as projects that add new data collection or collect additional biological specimens within ongoing investigations. The intent is to leverage existing resources when possible, while still leaving room for targeted, practical additions that make it possible to examine mechanisms, identify meaningful associations, or refine measurement strategies related to energy balance and cancer outcomes.

The award mechanism is the NIH Exploratory/Developmental Grant (R21), which is designed for early-stage or high-potential concepts that may not yet have extensive preliminary data. Consistent with the R21 structure, the project period is capped at 2 years. The budget limits are also clearly defined: applicants may request up to $275,000 in direct costs total across the 2-year period, with a maximum of $200,000 in direct costs in any single year. While the scientific scope is fixed around energy balance and cancer in humans, the FOA notes that the exact size and structure of each award can vary depending on the work proposed, and that actual awards depend on available funds and the quality and merit of applications received.

NIH anticipated making about three awards under this R21 announcement, though final numbers depend on appropriations, the number of strong submissions, and the requested budgets. The FOA also runs in parallel with a separate but scientifically identical announcement (PA-06-404) that uses the R01 mechanism, which is generally intended for larger, more mature research projects. In other words, applicants with smaller, more exploratory aims or short, focused pilot-style projects would typically align with this R21, while more extensive, fully powered projects might fit the companion R01 announcement.

Eligibility is broad. A wide variety of organization types may apply, including public or private institutions such as universities, colleges, hospitals, and laboratories; nonprofit and for-profit organizations; units of state and local government; eligible federal agencies; and domestic or foreign institutions. Faith-based and community-based organizations are explicitly eligible, and the announcement also includes eligibility for Indian/Native American tribal governments (both federally recognized and other than federally recognized) and tribally designated organizations. There is no cost sharing or matching requirement, which means applicants are not required to contribute non-federal funds to receive an award.

The opportunity is open to any qualified Project Director/Principal Investigator (PD/PI) with the appropriate expertise, institutional support, and resources to carry out the work. NIH also reiterates its standard encouragement for applications from individuals from underrepresented racial and ethnic groups and individuals with disabilities. Applicants may submit more than one application as long as each submission is scientifically distinct, which can be helpful for teams with multiple ideas that address different mechanisms, populations, or methods within the broader energy balance and cancer theme.

Administratively, this is a discretionary grant opportunity within NIH's health and research mission areas, linked to CFDA numbers 93.393 (Cancer Cause and Prevention Research) and 93.399 (Cancer Control). The original posting date was May 9, 2006, with multiple receipt dates (meaning there were several submission deadlines rather than a single closing date), and the program was later archived (archive date June 1, 2009). For full details, NIH provided an official announcement page and contact support through the NIH Office of Extramural Research (OER) webmaster for access or linking issues.

PA-06-405 is a National Institutes of Health (NIH) funding opportunity titled "Studies of Energy Balance and Cancer in Humans (R21)." It supports exploratory and developmental human-focused research on how energy balance relates to cancer, including cancer risk, prognosis, and quality of life.

What does "energy balance" mean in this announcement?

In this FOA, "energy balance" generally refers to the interplay among diet, physical activity, body weight and body composition, metabolism, and related behaviors or physiological processes that determine energy intake and expenditure.

What is the main goal of this funding opportunity?

The central goal is to improve understanding of which energy balance-related factors matter most and to clarify the biological or behavioral mechanisms that connect those factors to cancer risk, cancer prognosis, and quality of life during and after cancer treatment.

Is this opportunity limited to human research?

Yes. The announcement is specifically geared toward human-focused research.

What types of research projects does PA-06-405 encourage?

Can I use existing datasets for this R21?

Yes. The FOA explicitly allows new analyses of existing datasets, such as reanalyzing cohort, clinical, or population datasets to explore new hypotheses related to obesity, exercise, diet patterns, or metabolic markers and their relationships to cancer outcomes.

Does the FOA allow collection of new data or biological specimens?

Yes. In addition to reanalysis of existing data, the FOA allows projects that add new data collection or collect additional biological specimens within ongoing investigations.

What is the intended approach to using resources in this program?

The intent is to leverage existing resources when possible, while still allowing targeted, practical additions that enable mechanism-focused questions, identification of meaningful associations, or refinement of measurement strategies related to energy balance and cancer outcomes.

What grant mechanism is used for PA-06-405?

This opportunity uses the NIH Exploratory/Developmental Grant mechanism (R21), which is designed for early-stage or high-potential concepts that may not yet have extensive preliminary data.
