FTC sued Skechers over advertisements by Skechers that its shoes' caused muscle toning and weight loss. Skechers had clinical studies showing that its shoes did cause weight loss and muscle toning.
FTC found that the studies were biased. They were conducted by a chiropractor paid by Skechers. The data was inconclusive and possibly showed that the participants wearing Skechers shoes gained weight!
In the final settlement dated 5/16/2012, Skechers agreed to pay $40 million dollars fine. FTC further ordered that any future claim has to be substantiated by TWO independent clinical studies. The studies may be sponsored by the company but have to be done by independent groups and have to include control participants etc..etc..
Would it not be nice to apply the same standards to drugs?
The FDA requires only ONE clinical study to approve a drug or medical device. The study is always conducted by someone paid by the drug company and very often the company employees play a prominent role in conducting the clinical trials. The results of the study are analyzed a hundred different ways. If the drug is statistically better than placebo in one of these different analysis, then the FDA approves the drug!
