Physical Activity and Weight Control Interventions Among Cancer Survivors Effects on Biomarkers of Prognosis and Survival (R01) | Apply Online

Opportunity Summary:

The NIH grant opportunity PA 15-311, titled "Physical Activity and Weight Control Interventions Among Cancer Survivors: Effects on Biomarkers of Prognosis and Survival (R01)," supports research aimed at explaining how lifestyle change can influence cancer outcomes after diagnosis. The central focus is not simply whether physical activity or weight control helps cancer survivors, but exactly which biological or biobehavioral mechanisms are responsible for any improvements in prognosis and survival. In other words, the FOA is looking for studies that move beyond broad associations and instead pinpoint the pathways linking exercise and weight management to measurable changes in the body that matter for recurrence risk, disease progression, and long-term survival.

A key feature of this announcement is its emphasis on biomarker-driven, mechanism-focused intervention research in cancer survivors. Applicants are expected to test the effects of physical activity interventions alone, or physical activity combined with weight control strategies (either intentional weight loss or prevention of weight gain), on biomarkers tied to cancer prognosis. The FOA encourages investigators to base biomarker selection on prior animal studies or observational research, with a strong preference for established biomarkers that are not limited to insulin and glucose metabolism. That detail is important: while insulin-related pathways are common in obesity and cancer research, this FOA is explicitly trying to broaden the field toward additional mechanisms. It also highlights special interest in biomarkers obtained directly from tumor tissue, particularly when repeat biopsies are feasible, because tumor-based measures can offer more direct insight into how an intervention might influence the biology of the cancer itself.

The opportunity also reflects a realistic view of survivorship outcomes. Many cancer survivors will never experience a recurrence, yet they may face higher risks of other major health problems or show earlier signs of aging-related decline. Because of that, the FOA encourages the inclusion of biomarkers that capture comorbid disease risk and aging processes, such as cardiovascular disease-related markers, inflammatory or vascular indicators, and other measures relevant to overall health and functional longevity. This widens the scope from cancer-only endpoints to the broader clinical reality that survivorship often involves managing competing risks and long-term treatment consequences.

From a study design standpoint, NIH is looking for experimental approaches capable of supporting causal inference about mechanisms. The FOA specifically calls for rigorous experimental designs such as randomized controlled trials, as well as other structured designs like fractional factorial experiments that can efficiently test multiple intervention components or combinations. The point is to create studies where changes in physical activity and/or weight can be credibly linked to changes in pre-specified biomarkers, rather than relying on correlational evidence. Mechanistic clarity is the through-line: proposals should be designed to show which pathways change, how strongly they change, and how those changes plausibly connect to prognosis and survival.

Another major expectation is that projects be transdisciplinary and translational. Applicants are encouraged to build teams that combine behavioral intervention expertise (the ability to design and deliver effective physical activity and weight control programs) with cancer biology and other basic or clinical sciences aligned with the biomarkers and pathways under investigation. This could mean integrating oncology, exercise physiology, nutrition science, molecular pathology, immunology, endocrinology beyond glucose pathways, cardiovascular medicine, aging biology, biostatistics, and implementation-relevant expertise when appropriate. The underlying message is that behavioral interventions in survivors should be studied with the same biological precision often used for drug or targeted therapy development, while still being grounded in real-world survivorship needs.

In terms of administrative details, this is a discretionary grant opportunity using the NIH R01 mechanism, and it falls under CFDA numbers 93.393 (Cancer Cause and Prevention Research) and 93.399 (Cancer Control). There is no cost-sharing or matching requirement. The opportunity was posted on July 24, 2015, and the original and current closing date listed is September 7, 2018, with an archive date of October 8, 2018, indicating it is no longer active as a current competition but remains available as a reference. Eligible applicants are broad and include public and private institutions of higher education, nonprofits (including 501(c)(3) and non-501(c)(3)), small businesses, for-profit organizations (including those other than small businesses), state and local governments, tribal governments and tribal organizations, public housing authorities, independent school districts, special district governments, and additional categories such as faith-based or community-based organizations, minority-serving institutions (including HBCUs, HSIs, AANAPISIs, TCCUs), U.S. territories or possessions, and even non-U.S. entities/foreign organizations and regional organizations, as described in the eligibility text.

Overall, PA 15-311 is best understood as an NIH effort to tighten the link between survivorship lifestyle interventions and the biological evidence needed to explain why and how those interventions might improve outcomes. The FOA pushes the field toward well-controlled trials, carefully chosen biomarkers (especially beyond insulin/glucose), tumor-informed measures when possible, and integrated teams that can connect behavior change to cancer-relevant and comorbidity-relevant biology in a way that is credible, testable, and clinically meaningful.
