Trial Gone Wrong

A trial involving the testing of a new drug, in London went badly. This drug was intentioned to help with autoimmune disease or certain types of cancer. When the trial took place, moments after the drug was administered to volunteers, the volunteers given the actual drug started reating severly, becoming violently ill. One of the men given the placebo, a drug with no effect, recalls that the effects were instantaneous. The men given the actual drug were then rushed to the hospital for multiple organ failure, and two had to stay in intensive care. Later it was found that the men and families were not given complete information about what had occurred in the animal trials, of several deaths and severe illness. This makes me wonder, although the United States has intense laws regarding informed consent, isn't it important for the entire world to have a unified standard, or is it based upon personal opinions and decisions.
