VCU Human Research Protection Program (HRPP) Blog

The VCU HRPP is dedicated to facilitating ethically and scientifically sound research through robust review of research projects and through effective education and outreach to the VCU research community.


Protecting human subjects in research is paramount to ensure ethical, safe, and meaningful scientific advancements. Federal regulations, particularly 45 Code of Federal Regulations (CFR) 46, Subpart A, provide guidelines and requirements to protect the rights and well-being of research participants. One critical aspect of these regulations is the requirement for a scientific review of research protocols to assess their scientific merit. This guidance document aims to explain why a scientific review is essential in the ethical conduct of research involving human subjects and how it contributes to the minimization of risks to subjects, as specified in 46 CFR 111(a)(1)(i).

Ensuring Scientific Rigor:

Scientific research must adhere to rigorous standards to produce reliable and valid results. A scientific review evaluates the proposed research protocol’s scientific rigor, including its hypothesis, research design, methods, and statistical analyses. This process helps ensure the research is based on sound research design principles and does not unnecessarily expose subjects to risk.

Protecting Human Subjects:

A fundamental aspect of an Institutional Review Board (IRB) evaluation is to verify the scientific worthiness of human subject research while concurrently safeguarding the rights and well-being of human participants, as prescribed in 46 CFR 111(a)(1)(i). Research devoid of scientific merit is deemed unethical, and exposing human subjects to potential risks or harm becomes ethically indefensible.

Consequently, within the assessment of a protocol’s scientific merit, scientific reviewers can pinpoint potential risks and benefits connected to the research. This, in turn, allows the IRB to deliberate on the equilibrium between risks and benefits, the adequacy of informed consent procedures, and the societal value of producing generalizable knowledge. These deliberations empower both the research institution and the Institutional Review Board (IRB) to make informed judgments regarding the ethical justifiability of the study while ensuring that potential benefits outweigh the risks for participants and adhere to the principles of sound research design.

Resource Allocation:

Scientific reviews help allocate limited resources effectively. Research institutions and funding agencies often have limited resources available for research. By evaluating the scientific merit of proposed studies, reviewers can prioritize research projects that are more likely to yield valuable insights and contribute to the advancement of knowledge while minimizing unnecessary risks to subjects.

Enhancing Research Quality:

High-quality research is essential for scientific progress. Scientific reviews promote the development of well-designed and methodologically sound research protocols. This, in turn, leads to research that is more likely to produce meaningful and valid results, thereby enhancing the overall quality of research conducted with human subjects while minimizing unnecessary risks.

Ethical Oversight:

Ethical considerations are integral to human subject research. Scientific reviews ensure research protocols adhere to ethical principles, such as respect for autonomy, beneficence, and justice. Reviewers can identify potential ethical concerns, such as undue risks, and recommend necessary revisions to align the research design with sound research practices, minimizing risks to subjects.

Compliance with Regulations:

Federal regulations, including 45 CFR 46, require institutions conducting human subject research to establish effective processes for scientific review. Compliance with these regulations is not only a legal requirement but also demonstrates an institution’s commitment to ethical research practices, including the minimization of risks to subjects through the use of procedures consistent with sound research design and by avoiding unnecessary exposure to risk.

In summary, a scientific review of research protocols is essential for ensuring the scientific merit and ethical conduct of research involving human subjects. It serves as a critical safeguard for the welfare and rights of research participants, promotes scientific rigor, enhances research quality, and helps allocate resources wisely while ensuring compliance with federal regulations. Moreover, it contributes significantly to the minimization of risks to subjects, in accordance with 46 CFR 111(a)(1)(i), by ensuring that research procedures are consistent with sound research design and do not unnecessarily expose subjects to risk. Institutions and researchers must embrace the importance of scientific review as an integral part of their commitment to ethical and responsible research practices.
