Biomechanisms of Peripheral Nerve Damage by Anti Cancer Therapy (R21) | Apply Online

Opportunity Summary:

The NIH grant opportunity "Biomechanisms of Peripheral Nerve Damage by Anti-Cancer Therapy (R21)" (Funding Opportunity Number PA-12-083) was created to push forward basic biological research on chemotherapy-induced peripheral neuropathy (CIPN), a form of peripheral nervous system damage triggered by pharmacologic cancer treatments. The FOA is aimed at closing a persistent knowledge gap: while acquired peripheral neuropathy has been heavily studied in the context of diabetes and inherited disorders, the nerve injuries caused by cancer therapies have not received the same depth of mechanistic investigation. The program is essentially a call for neuroscience and neuropathy researchers to bring the tools, models, and insights they have developed in other neuropathy fields to the distinct and clinically important problem of CIPN, where patients can experience long-lasting and sometimes treatment-limiting nerve dysfunction.

The scientific emphasis is on understanding how cancer therapies initiate and sustain peripheral nerve damage at a molecular and cellular level. The announcement highlights the need for more data that can explain what exactly is happening to neurons and peripheral nerve structures during and after exposure to anti-cancer agents, and which biological targets are most responsible for starting CIPN and keeping it going. Importantly, the FOA signals that research should not be limited to pain alone. While peripheral neuropathic pain is a major concern, NIH explicitly invites preclinical work that also focuses on other sensory disturbances commonly reported by patients, such as paresthesias (abnormal sensations like tingling or pins-and-needles) and peripheral anesthesias (reduced sensation or numbness). This broader symptom focus reflects the reality of CIPN, where quality of life and functional impairment can stem from numbness, loss of proprioception, and altered sensory processing just as much as from pain.

The longer-term purpose of the FOA is translational in spirit even though it is framed as basic biology: by building a solid mechanistic foundation for CIPN, the research supported under this opportunity is meant to enable rational design of interventions that can prevent CIPN from developing or treat it once it begins. In other words, rather than relying on trial-and-error symptom management, the goal is to identify actionable molecular pathways, cellular events, and biological targets that can be used to create more effective, mechanism-driven therapeutics or prevention strategies. The mechanism of support is the NIH R21, which is typically used for exploratory or early-stage projects that can open up new lines of investigation or generate critical proof-of-concept data.

From an administrative standpoint, this was a discretionary NIH grant opportunity categorized under Education and Health, with CFDA listings that include Cancer Control (93.399) and Extramural Research Programs in the Neurosciences and Neurological Disorders (93.853). The FOA did not require cost sharing or matching. It was posted and created on January 17, 2012, and it carried an original and final closing date of May 7, 2015, with an archive date of June 7, 2015. The listed award ceiling was $200,000. Even though the opportunity is now archived, the details are useful as a template for understanding NIH interest areas and the kinds of CIPN projects NIH has encouraged.

Eligibility for this FOA was broad and included many types of organizations: public and private institutions of higher education, nonprofits (including 501(c)(3) and certain non-501(c)(3) entities), small businesses, for-profit organizations (other than small businesses), independent school districts, and multiple levels of government (state, county, city/township, special district governments), as well as public housing authorities/Indian housing authorities. It also explicitly included a wide set of mission- and community-focused institutions and organizations, such as Historically Black Colleges and Universities (HBCUs), Hispanic-serving institutions, tribally controlled colleges and universities (TCCUs), Alaska Native and Native Hawaiian serving institutions, and faith-based or community-based organizations, along with regional organizations and U.S. territories or possessions. Notably, foreign participation was allowed: non-U.S. (foreign) institutions could apply, non-U.S. components of U.S. organizations were eligible, and foreign components as defined by the NIH Grants Policy Statement were permitted. The sponsoring agency was the National Institutes of Health, and the full announcement was hosted through the NIH grants guide at http://grants.nih.gov/grants/guide/pa-files/PA-12-083.html, with technical access and linking help directed to the NIH OER Webmaster (FBOWebmaster@OD.NIH.GOV).

In practical terms, the FOA can be read as a focused push to grow the foundational science behind CIPN: encouraging preclinical mechanistic work that goes beyond describing symptoms and instead explains causation, identifies key biological drivers, and sets the stage for targeted prevention and treatment approaches. The message is that CIPN is not just a side effect to be managed, but a neurobiological injury process that can be understood in detail and, with the right mechanistic insights, potentially interrupted or reversed.
