Opportunity Summary:

The Drug Target Development and Validation for Antimicrobial Resistant Pathogens (R21/R33) opportunity (Funding Opportunity Number RFA-AI-13-019) was a National Institutes of Health (NIH) discretionary grant program aimed at accelerating research that moves from early discovery toward translation in the specific area of antimicrobial resistance. The central goal was to support projects that identify, characterize, and validate new antimicrobial drug targets in select antibiotic-resistant bacterial pathogens, with the longer-term intention of enabling new therapeutic interventions. In practical terms, the program was set up to encourage work that goes beyond simply finding an interesting bacterial gene or pathway and instead builds a defensible case that a target is both biologically important to the pathogen and realistically actionable for drug development.

A key feature of this announcement is the use of the R21/R33 phased innovation mechanism. The R21 portion is typically used for high-impact, exploratory, and early-stage activities, such as initial target discovery, feasibility experiments, preliminary validation, and development of assays or enabling tools. If predefined milestones are met, the project can transition into the R33 phase, which is generally intended to support more advanced, milestone-driven development work. For a topic like antimicrobial target validation, that phased structure is a way of pushing projects to start with strong proof-of-concept experiments and then, if successful, move into more rigorous validation and translational steps that could include deeper mechanistic characterization, improved assays for screening, or additional validation in relevant models. The emphasis on milestones is important because it signals that NIH expected clear, measurable progress gates rather than open-ended basic research alone.

The scientific scope was described as "basic to translational," meaning the program was interested in a continuum of work that begins with foundational biology and advances toward drug discovery readiness. That typically includes things like demonstrating that inhibiting a target impairs bacterial survival, virulence, persistence, or transmission; establishing that the target is essential or conditionally essential under clinically relevant conditions; showing that the target is conserved across strains of concern (or intentionally strain-specific if that is the strategy); and assessing whether the target can be modulated by small molecules or other therapeutic modalities. It also commonly involves building the experimental infrastructure needed for downstream discovery, such as biochemical or cell-based assays that are robust enough to support screening or structure-function studies that clarify how inhibition might work. The announcement specifically framed this work in the context of antimicrobial-resistant bacterial pathogens, highlighting the public health urgency of developing new strategies that can bypass existing resistance mechanisms.

From an administrative and funding standpoint, the opportunity was posted March 26, 2013, with an original and current closing date of July 18, 2013, and it was archived on August 18, 2013. NIH estimated total funding at approximately $3.5 million for the program. The funding instrument type was a grant, and the activity category fell under health. The CFDA program numbers associated with the announcement were 93.855 (Allergy and Infectious Diseases Research) and 93.856 (Microbiology and Infectious Diseases Research), reflecting its placement within NIH infectious disease and microbiology priorities. There was no cost sharing or matching requirement, which generally lowers barriers for applicants and is typical of many NIH research grants.

Eligibility was broad and included many organizational types across the public, private, academic, nonprofit, and governmental spectrum. Eligible applicants included public and state-controlled institutions of higher education and private institutions of higher education, nonprofits with or without 501(c)(3) status (with the noted exception language in the listing), for-profit organizations (including but not limited to small businesses), and a range of governmental entities such as state governments, county governments, city or township governments, special district governments, independent school districts, and public housing authorities/Indian housing authorities. The announcement also explicitly included eligibility for tribal governments and tribal organizations, including Federally recognized Native American tribal governments and other tribal entities, as well as Tribally Controlled Colleges and Universities (TCCUs). Beyond that, it listed several institution categories often highlighted in federal funding opportunities, such as Historically Black Colleges and Universities (HBCUs), Hispanic-serving Institutions, Alaska Native and Native Hawaiian Serving Institutions, and Asian American Native American Pacific Islander Serving Institutions (AANAPISIs), along with faith-based or community-based organizations where applicable.

Notably, non-U.S. entities were eligible: foreign organizations and foreign institutions could apply, non-domestic components of U.S. organizations were eligible, and foreign components (as defined in the NIH Grants Policy Statement) were allowed. This is significant for antimicrobial resistance research because resistant pathogens, their evolution, and their clinical impact are global, and the best expertise, strain collections, or clinical contexts may exist outside the United States.
