Ethical guidelines in clinical research

 

ETHICAL GUIDELINES IN CLINICAL RESEARCH

GENERAL INTRODUCTION

Ethical guidelines in clinical research refer to the general principles of biomedical research involving human participants.
In India, these guidelines are issued by the Indian Council of Medical Research (ICMR) and are commonly known as the ICMR Code of Ethics.

ICMR CODE CONSISTS OF:

a) Statement of General Principles on research involving human participants in biomedical research.
b) Statement of Specific Principles on research involving human participants in specific areas of biomedical research.

These statements and principles may be modified, amended, substituted, or added from time to time as per scientific and ethical advancements.

GENERAL STATEMENT

Medical and related research involving human beings as research participants should ensure that:

1.     Purpose of Research
The research should be directed towards the advancement of knowledge about the human condition and for the benefit of society as a whole.

2.     Conduct of Research
Research must be conducted in a morally, ethically, and professionally sound manner.
The dignity, well-being, transparency, and fair professional treatment of participants must be maintained.

3.     Evaluation and Safety
Continuous evaluation at all stages of research is mandatory to ensure the safety and protection of human life.

GENERAL ETHICAL PRINCIPLES

All research involving human subjects must be conducted in accordance with three basic ethical principles, namely:

  1. Respect for Persons
  2. Beneficence
  3. Justice

These guidelines focus on the application of these principles in biomedical research involving human participants.

a) RESPECT FOR PERSONS

Respect for persons includes two fundamental ethical considerations:

1.     Respect for Autonomy

    • Every individual has the right to make informed and voluntary decisions.
    • Autonomy requires:
      • Rational capacity
      • Freedom from coercion or undue influence
    • Researchers must respect the decisions of autonomous individuals.

2.     Protection of Persons with Impaired or Diminished Autonomy

    • Some individuals (e.g., children, mentally ill, unconscious patients) may not be capable of self-determination at all times.
    • Such participants require special protection and additional safeguards.

b) BENEFICENCE

Beneficence refers to the ethical obligation to:

  • Maximize possible benefits
  • Minimize potential harms, risks, and wrongs

Researchers must ensure that the risk-benefit ratio is favorable and scientifically justified.

c) JUSTICE

In research ethics, justice primarily refers to distributive justice, which means:

  • Equitable selection of research participants
  • Fair distribution of both the burdens and benefits of research

No group should be unfairly burdened or unjustly excluded from the benefits of research.

TWELVE BASIC ETHICAL PRINCIPLES

(Common to all areas of Biomedical Research involving Human Participants)

1) Principle of Essentiality

All biomedical research involving human subjects must be absolutely essential and undertaken only after careful consideration of all possible alternatives.
Human participants should be used only when the research question cannot be answered otherwise.

2) Principle of Voluntariness and Informed Consent

The concepts of voluntariness and informed consent must apply:

  • To the community as a whole, and
  • To each individual research participant

Participation should be free, voluntary, informed, and without coercion or undue influence.

3) Principle of Non-Exploitation

Irrespective of socio-economic status, literacy, or education level, all research participants must be:

  • Fully informed about risks, benefits, and consequences of the research
  • Protected from exploitation, inducement, or unfair advantage

4) Principle of Privacy and Confidentiality

The identity, data, and records of research participants must be:

  • Kept confidential
  • Not disclosed without valid scientific or legal justification

5) Principle of Precaution and Risk Minimization

Due care and caution must be taken to ensure that:

  • Participants are exposed to minimum possible risk
  • Irreversible harm is avoided
  • Risks are reasonable in relation to anticipated benefits

6) Principle of Professional Competence

All biomedical research must be conducted only by competent, trained, and qualified persons who have:

  • Adequate scientific knowledge
  • Appropriate ethical training and experience

7) Principle of Accountability and Transparency

Research must be conducted in a:

  • Fair, honest, impartial, and transparent manner
  • Research records and data must be accurately maintained and preserved for a reasonable period

8) Principle of Maximization of Public Interest and Distributive Justice

Research should be conducted to:

  • Benefit humanity as a whole, and
  • Not only the socially or economically privileged sections

There must be equitable distribution of benefits and burdens.

9) Principle of Institutional Arrangements

All necessary institutional approvals, ethics committee clearances, and administrative arrangements must be:

  • Made in a bonafide and transparent manner
  • Properly documented, maintained, and preserved

10) Principle of Public Domain

After due experimentation and evaluation:

  • Research results should be brought into the public domain
  • Dissemination should occur through scientific publications, in accordance with laws and regulations in force

11) Principle of Totality of Responsibility

All persons directly or indirectly involved in research have the responsibility to:

  • Continuously monitor and review the research
  • Take appropriate remedial action at all stages to safeguard participants

12) Principle of Compliance

All stakeholders must strictly adhere to:

  • Applicable rules, regulations, ethical guidelines, and norms
  • Directions issued by regulatory authorities and ethics committees

BASIS OF THESE GUIDELINES

These ethical principles are based on national and international frameworks including:

  • ICMR – Indian Council of Medical Research
  • COC / COSCO – Codes of Conduct
  • CCP – Clinical and Community Practice principles
  • International Ethical Guidelines (e.g., Declaration of Helsinki, CIOMS)

 

ETHICS REVIEW BOARD (ERB)

DEFINITION

An Ethics Review Board (ERB) is an independent body consisting of medical/scientific and non-medical/non-scientific members, whose primary responsibility is to protect the rights, safety, dignity, and well-being of human participants involved in biomedical and clinical research.

ERB IS ALSO KNOWN AS:

  • Institutional Ethics Committee (IEC)
  • Institutional Review Board (IRB)
  • Ethics Committee (EC)

(All terms are used interchangeably in different regulatory frameworks.)

ROLE AND FUNCTIONS OF ERB

  • Ethical review of research protocols
  • Risk–benefit assessment
  • Protection of vulnerable populations
  • Review of informed consent process
  • Ongoing monitoring of approved research
  • Ensuring compliance with ethical and regulatory guidelines

COMPOSITION / CONSTITUTION OF IRB (IEC)

The composition of the IRB should ensure adequate expertise, independence, diversity, and ethical competence to review the scientific, medical, and ethical aspects of proposed research.

NUMBER OF MEMBERS

  • The IRB should consist of minimum 7–15 members
    (ICMR recommends at least 7 members; many institutions have 9–15)

TYPICAL COMPOSITION OF IRB / IEC

1.     Chairperson

    • Preferably from outside the institution
    • Ensures independence and impartiality

2.     Basic Medical Scientist(s) (1–2)

    • From disciplines such as pharmacology, physiology, microbiology, etc.

3.     Clinician(s) (1–2)

    • Preferably from different specialties
    • May be from the same or different institutions

4.     Legal Expert / Retired Judge

    • Provides guidance on legal and regulatory compliance

5.     Social Scientist / Social Worker

    • Represents social, cultural, and community perspectives

6.     Philosopher / Ethicist / Theologian

    • Addresses ethical, moral, and value-based issues

7.     Lay Person / Community Representative

    • Represents the general public’s viewpoint
    • Should be non-scientific and non-medical

8.     Member Secretary

    • Usually from within the institution
    • Responsible for coordination, documentation, and communication

IMPORTANT POINTS (FOR EXAMS)

  • Chairperson should be external → ensures independence
  • Combination of scientific + non-scientific members is mandatory
  • Lay person ensures community perspective
  • Legal expert ensures regulatory compliance
  • Member Secretary handles administrative functions
