The era of valid informed consent.

Area of Science:

• Biomedical Ethics
• Clinical Trial Methodology
• Pharmacology

Background:

• Informed consent is crucial for clinical trials, but legal and valid consent present distinct challenges.
• Legal consent often involves signing documentation, while valid consent requires participant awareness of all risks.
• Current pre-clinical data, primarily from animal studies, lacks reliable human extrapolation.

Purpose of the Study:

• To analyze the limitations of informed consent in clinical trials.
• To highlight the inadequacy of animal data for ensuring valid participant consent.
• To advocate for the adoption of human-based research methodologies.

Main Methods:

• Review of informed consent principles in legal and ethical contexts.
• Analysis of the scientific limitations of animal models in predicting human drug responses.
• Exploration of modern molecular biology and human genetics techniques.

Main Results:

• Signing legal consent documents does not guarantee a participant's full understanding of risks.
• Animal experiment data cannot be reliably extrapolated to human subjects, undermining valid consent.
• Existing methodologies prevent participants from giving truly informed consent due to data uncertainties.

Conclusions:

• Valid informed consent in clinical trials is compromised by reliance on animal data.
• A paradigm shift to human-based research is essential for ethical clinical trials.
• Advanced molecular and genetic methods offer a more reliable basis for human-based studies.
