Ethics of clinical trials

Area of Science:

• Medical Ethics
• Clinical Research

Background:

• Clinical trials have evolved significantly, with gross abuses largely eliminated but subtle ethical issues remaining.
• Modern clinical drug trials necessitate strict adherence to ethical and legal requirements.

Purpose of the Study:

• To review the historical progress of clinical trial ethics.
• To highlight key ethical principles and challenges in conducting clinical trials.
• To propose measures for ensuring scientifically and ethically sound clinical trials.

Main Methods:

• Literature review and internet search on clinical trial history, medical ethics, and good clinical practice.
• Analysis of foundational ethical guidelines, including the Oath of Hippocrates and the Helsinki Declaration.
• Examination of ethical principles such as autonomy, non-maleficence, beneficence, and justice.

Main Results:

• The Helsinki Declaration provides a framework emphasizing informed consent, risk-benefit assessment, and subject protection.
• Key ethical challenges include obtaining free informed consent, managing post-trial medication use, addressing drug toxicities, and responsible publication of results.
• Adherence to principles like autonomy, non-maleficence, beneficence, and justice is crucial for ethical research.

Conclusions:

• Strengthening regulatory bodies and adhering to global standards are vital for enhancing research subject protection.
• Partnerships among stakeholders, public engagement, and specialized training for research personnel are recommended.
• Ethically sound clinical trials require continuous vigilance and adaptation to evolving ethical considerations.
