“What GAO FoundThe Food and Drug Administration (FDA) awards priority review vouchers (PRV) to drug sponsors that develop drugs for tropical diseases or rare pediatric diseases or to use as medical countermeasures. The PRV—which can be sold to another drug sponsor—may be redeemed later to receive priority review from FDA with a targeted review time of 6 months, rather than the 10-month standard review, for a drug application of the PRV holder's choice. The potential for additional revenue from either marketing a drug about 4 months sooner or from selling the PRV could provide an incentive for drug sponsors to develop drugs for these diseases or conditions. From fiscal year 2009, when the first PRV was awarded, through fiscal year 2019, FDA awarded 31 PRVs, mostly for drugs to treat rare pediatric diseases. Of the 31 PRVs awarded by FDA,17 were sold to another drug sponsor for prices ranging from about $67 million to $350 million, according to available data. As of September 30, 2019, available data show that drug sponsors had redeemed 16 of the 31 PRVs to obtain a shorter FDA review time for drugs to treat conditions and diseases such as human immunodeficiency virus (HIV), type 2 diabetes, and different forms of arthritis. These drug applications may not otherwise qualify for priority review.”
