Introduction

  • Informed consent is a cornerstone of research ethics, but it is neither necessary nor sufficient to guarantee the ethical conduct of clinical research.

  • We shall explore the broader and more comprehensive ethical framework by drawing upon the foundational philosophies of major codes, declarations, and other relevant documents concerning research involving human subjects.

  • This framework consists of seven distinct requirements, which, when all are fulfilled, ensure the ethical nature of clinical research.

I. Value:

  • The first requirement, ‘value,’ emphasizes that clinical research should contribute to the enhancement of health or knowledge.
  • In other words, the research should hold the potential to produce valuable results that can benefit society.
  • This principle aligns with the fundamental ethical notion that research should have a purpose and should not be conducted merely for the sake of research itself.
  • Clinical research should promise substantial benefits, whether in the form of improved patient care or increased understanding of diseases and treatments.

II. Scientific Validity:

  • The second requirement, ‘scientific validity,’ mandates that clinical research must be conducted with methodological rigor.
  • A study that lacks scientific validity not only wastes resources but also risks the well-being of research subjects.
  • Sound research design, data collection, and analysis are crucial to ensure that the findings can be trusted.
  • Without rigorous scientific methods, any potential benefits derived from the research may remain elusive.

III. Fair Subject Selection:

  • ‘Fair subject selection’ is the third requirement, emphasizing that the choice of research subjects should be driven by scientific objectives rather than vulnerability or privilege.
  • It also stresses the importance of distributing risks and benefits fairly.
  • Communities selected as study sites and individual subjects included should be determined by scientific considerations, and the research should not exploit vulnerable populations.
  • The principle of justice lies at the core of this requirement, promoting fairness and equitable distribution of the burdens and benefits of research.

IV. Favorable Risk-Benefit Ratio:

  • The fourth requirement, ‘favorable risk-benefit ratio,’ calls for the minimization of risks and the enhancement of potential benefits.
  • The ethical duty is to ensure that potential benefits to individuals and society significantly outweigh the risks.
  • This criterion is rooted in the principle of beneficence and obliges researchers to prioritize the safety and well-being of research subjects.
  • Balancing risks and benefits is crucial to avoid unnecessary harm.

V. Independent Review:

  • To ensure the ethical conduct of research, the fifth requirement mandates ‘independent review.’
  • Research must be reviewed and approved by individuals or bodies unaffiliated with the research project.
  • This independent review assesses the study’s design, ethics, and potential risks, and it can amend or terminate the research if necessary.
  • The aim here is to maintain objectivity and prevent conflicts of interest, thus upholding the principles of autonomy and fairness.

VII. Respect for Enrolled Subjects:

  • The final requirement, ‘respect for enrolled subjects,’ underscores the importance of protecting subjects’ privacy, providing the opportunity to withdraw from the study, and ensuring ongoing monitoring of their well-being.
  • This requirement acknowledges that research subjects are not mere data points but individuals deserving respect and protection. Upholding the dignity and rights of research subjects is central to research ethics.
