Which act was responsible for the introduction of the requirement for clinical trial patient consent?

The Kefauver-Harris Amendment is recognized for instituting the requirement for informed consent from patients participating in clinical trials. This amendment was enacted in response to concerns about the safety and efficacy of drugs marketed in the United States, particularly following the thalidomide tragedy, which underscored the need for stricter regulation of pharmaceutical products.

By mandating informed consent, the amendment ensures that participants are fully aware of the nature of the trial, any potential risks involved, and their rights as participants. This legislation aimed to enhance the protection of human subjects involved in clinical research and to improve the overall standards for drug approval processes.

The other acts mentioned, while significant in their own right, do not directly address the requirement for consent in clinical trials. The Controlled Substances Act primarily focuses on regulating narcotics and controlled substances. The FDA Modernization Act made advancements in drug approval processes but did not specifically introduce informed consent requirements. The Food, Drug, and Cosmetic Act laid the groundwork for drug regulation but came before the Kefauver-Harris Amendment, which is why it lacked the specific provisions for clinical trial patient consent.
