Kefauver Harris Amendment

Kefauver Harris Amendment

The U.S. Kefauver Harris Amendment or "Drug Efficacy Amendment" is a 1962 amendment to the Federal Food, Drug, and Cosmetic Act.

It introduced a requirement for drug manufacturers to provide proof of the effectiveness and safety of their drugs before approval [1] [2] , required drug advertising to disclose accurate information about side effects, and stopped cheap generic drugs being marketed as expensive drugs under new trade names as new "breakthrough" medications.

Background

The amendment was a response to the Thalidomide tragedy, in which thousands of children were born with birth defects as a result of their mothers taking thalidomide for morning sickness during pregnancy. The bill by U.S. Senator Estes Kefauver, of Tennessee, and U.S. Representative Oren Harris, of Arkansas, required drug manufacturers to provide proof of the effectiveness and safety of their drugs before approval.

It introduced a "proof-of-efficacy" requirement, that was not present before.[1] In addition, the Amendment required drug advertising to disclose accurate information about side effects and efficacy of treatments. Finally, cheap generic drugs could no longer be marketed as expensive drugs under new trade names as new "breakthrough" medications, as they were prior to the amendment.

The law was signed by President John F. Kennedy on October 10, 1962.

Effect

The Kefauver Harris Amendment strengthened the U.S. Food and Drug Administration's control of experimentation on humans and changed the way new drugs are approved and regulated. Before the Thalidomide scandal in Europe, U.S. drug companies only had to show their new products were safe. After the passage of the Amendment, an FDA New Drug Application (NDA) would have to show that a new drug was both safe and effective (previously the 1938 Food, Drug and Cosmetic Act was the main law that regulated drug safety). Informed consent was required of patients participating in clinical trials, and adverse drug reactions were required to be reported to the FDA.

The Drug Efficacy Study Implementation was begun to classify all pre-1962 drugs that were already on the market as either effective, ineffective, or needing further study.

Estes Kefauver considered the Amendment his "finest achievement" in consumer protection[citation needed].

Louis Lasagna, then a prominent clinical pharmacologist at the University of Rochester, advised Congress about the proper conduct of clinical research during the 1962 hearings leading up to passage of the Amendment.

The law also exempted from the "Delaney clause" (a 1958 amendment to the Food, Drugs, and Cosmetic Act of 1938) certain animal drugs and animal feed additives shown to induce cancer, but which left no detectable levels of residue in the human food supply.
