Evaluation Criteria
Overall Impact
Reviewers assess the likelihood of the project to exert a sustained, powerful influence on the research field(s) involved.
Scored Review Criteria
Factor 1. Importance of the Research (Significance and Innovation):
How the proposed research advances understanding of biological mechanisms contributing to cancer health disparities in underrepresented and/or underserved populations.
Whether the project breaks new ground, extends previous discoveries, or develops novel techniques/methodologies.
Factor 2. Rigor and Feasibility (Approach):
Whether the approach is appropriate to evaluate how biology may influence risk, incidence, and/or progression of cancer in underrepresented and underserved populations.
The rigor of the experimental design and methodology.
Factor 3. Expertise and Resources (Investigator(s) and Environment):
Whether the investigator(s) possess demonstrated background, training, and expertise for the proposed work.
For multidisciplinary teams, the quality of the leadership plan and how collective expertise contributes to project success.
Whether institutional resources are appropriate for successful execution of the work.
Additional Review Criteria (Not scored, but considered for overall impact)
Protections for Human Subjects: Justification for involvement, adequacy of protection, potential benefits, importance of knowledge gained, data and safety monitoring (if applicable).
Vertebrate Animals: Justification for use, appropriateness of species, interventions to minimize discomfort, justification for euthanasia method (if applicable).
Biohazards: Assessment of significant hazards and proposed protection measures.
Resubmissions: Evaluation of the full application as newly presented.
Additional Review Considerations (Not scored, but considered for overall impact)
Authentication of Key Biological and/or Chemical Resources: Evaluation of plans for validating resources.
Budget and Period of Support: Evaluation of whether the budget and requested duration are justified and reasonable relative to the proposed research.
Compliance & Special Requirements
Regulatory Compliance
Awards are made under the authority of Sections 301 and 405 of the Public Health Service Act as amended (42 USC 241 and 284) and Federal Regulations 42 CFR Part 52 and 2 CFR Part 200.
Recipients must comply with all applicable nondiscrimination laws, as agreed upon during SAM.gov registration.
For activities involving health IT, recipients must use health IT that meets standards and implementation specifications adopted in 45 CFR part 170, Subpart B, if applicable.
Mandatory disclosure of violations of federal criminal law involving fraud, bribery, or gratuity potentially affecting the federal award (2 CFR 200.113).
Data Protection & Cybersecurity
A Data Management and Sharing Plan is required for all projects that generate scientific data.
If recipients, subrecipients, or third-party entities have ongoing access to HHS systems or handle PII/PHI from HHS, they must develop plans and procedures modeled after the NIST Cybersecurity framework.
Ethical & Research Standards
Compliance with ethical standards for research involving human subjects (45 CFR Part 46) and vertebrate animals is required.
Research must be basic research focusing on biological/genetic causes and mechanisms of cancer health disparities.
Explicitly, studies investigating age or sex disparities without race/ethnicity variables are not solicited.
Behavioral, social, environmental, or community-based studies must incorporate biological mechanisms to be responsive.
Special Considerations
This grant utilizes the R21 (Exploratory/Developmental Research Grant) mechanism, intended for high-risk, high-reward early-stage exploratory projects that may lead to breakthroughs or novel techniques.
Clinical trials are NOT allowed for this funding opportunity.
The NOFO aims to aid and facilitate the growth of a nationwide cohort of scientists in cancer health disparities research and support early-stage exploratory projects that can lead to future in-depth mechanistic studies (like R01 projects).
