FDA Scraps Helsinki Declaration on Protecting Human Subjects

In the mid-1990s, the National Institutes of Health ran a clinical trial in Africa testing whether a new antiretroviral drug to combat AIDS worked to prevent mother-child transmission. The trial created an ethical uproar because the control group received a placebo instead of an older anti-AIDS drug called AZT, which had already been proven successful in reducing the number of babies who contracted HIV from their mothers.

To critics, failure to provide a proven therapy to participants in this and similar trials was a basic violation of standards outlined in the Helsinki Declaration on protecting human subjects in research, originally adopted by the World Medical Association in 1964. But to the U.S. Food and Drug Administration and the drug industry, to which it had grown increasingly close over the course of the 1990s, it contradicted its longstanding policy of only requiring trials showing that a new drug was "better than nothing," i.e., better than placebo, to win regulatory approval. If the drug industry were to closely adhere to the Helsinki Declaration, it would always have to run comparison trials if an effective drug were already available.
