The manufacturers of many drugs granted accelerated approval by the FDA do not complete timely confirmatory trials of the drugs’ efficacy, according to a recent study published in the journal Health Affairs — meaning that the pricing for many accelerated approval drugs has nothing to do with their clinical efficacy. The study’s author tells AIS Health, a division of MMIT, that “the market doesn’t work very well” for drugs that have received accelerated approval, and “what it leads us to is overpaying at the beginning and underpaying, potentially, later.”
After a drug is granted accelerated approval, the FDA mandates that the drug be evaluated using confirmatory clinical trials. The accelerated approval designation is given to new, unproven drugs that could potentially meet a dire need for a new or more effective therapy to treat a terminal disease. The intention behind the confirmatory trial system is to make sure that the drug actually does what its developer says it will.
