Study Notes

Overview of FDA and Clinical Drug Trials

The controlled clinical trial's purpose is to validate drug discoveries made through observation and research in lab and clinical settings.
The FDA stands as a leading authority in overseeing clinical drug trials, evolving from ancient practices of medical observation.

Historical Milestones

In the early 20th century, therapeutic reforms led to the establishment of well-controlled drug trials, combining lab analysis with clinical studies.
The 1938 U.S. Food, Drug, and Cosmetic Act initiated pre-market safety evaluations for new drugs, allowing the FDA to review safety data.
The 1962 Drug Amendments mandated that drug approvals depend on both safety and "substantial evidence" of efficacy from clinical trials, following a global drug crisis.

The Role of the FDA

Originally, the FDA acted as a neutral evaluator, but over time it became more involved in drug development and clinical trial design to improve standards.
The Drug Efficacy Study (DES), initiated post-1962 amendments, re-evaluated previously approved drugs for efficacy, assessing them through expert panels.

Drug Approval Processes

The FDA faced challenges in removing ineffective drugs from the market and created the "Treatment IND" program in 1987, allowing patients access to investigational drugs outside the usual trials.
Regulations in 1985 required drug approvals to be based on a comprehensive safety summary, enhancing evaluation processes.

Focus on AIDS and Parallel Track Approval

In 1988, new regulations mandated disclosure of AIDS drug INDs to improve patient access and recognized the importance of the Treatment IND program.
Parallel track approval processes were established from 1990 to 1992, expediting certain drug reviews for broader patient access.

Data Analysis and Personalized Medicine

The FDA has emphasized improving data analysis from clinical trials, particularly inspired by the AIDS crisis.
Surrogate endpoints have been recognized as valuable in certain contexts, correlating indirect measurements with clinical outcomes.
The ongoing evolution of drug development is paving the way for personalized medicine, while randomized clinical trials remain integral to the process.

Conclusion

The FDA's approach to clinical drug trials reflects an evolving understanding of the need for rigorous efficacy and safety evaluations to ensure public health.
