In the US, the current Prescription Drug User Fee Act (PDUFA) is due to expire in September 2022. A recent report calls for the new iteration of the act (VI) to increase Food and Drug Administration’s (FDA) authority to promote generic competition .
PDUFA VI: FDA could promote generics competition
Home/Policies & Legislation | Posted 29/07/2022 0 Post your comment
The Brookings Institution’s report has highlighted some concerns within FDA’s current regulatory processes. Specifically, these relate to three measures to promote improved generic drug competition: the Citizen Petition mechanism; the approval of ‘complex generic drugs’; and generic drug ‘parking’.
Under these , petitioners can ask FDA to reject or delay new drugs as additional review is ‘necessary to protect the public health’. However, it is clear to the report authors that these petitions are generally used by companies to delay competition and maintain market position. The authors suggest to ‘Strengthen the FDA’s authority to dismiss petitions and penalize non-meritorious filers by instituting time limits and associated penalties’, and ‘improve the transparency of the FDA’s review of citizen petitions by requiring the agency to report more details about delays and the agency’s review process’.
Complex generics are small molecule non-biological drugs that have difficulty establishing bioequivalence. The report highlights that an issue facing complex generics is related to the FDA guidance on drug-device combinations, also known as the ‘sameness standard’ and transparency. It suggests that the sameness standard be relaxed from substantial equivalence to functional equivalence on drug-device combinations. In addition, a streamlined review of ingredients for injectable complex generics could be introduced and the report highlighted some potential legislative options for which FDA could supply further clarification.
Generic Drug Parking
This is a practice whereby the companies who are the first to apply for FDA approval with a generic candidate pause at the tentative approval stage. The report notes that some reasons for this ‘parking’ are justified but not all. To prevent unjustified parking, the report authors suggest amendment to provisions surrounding the existing, 180-day exclusivity reward for patent challenges. They state that this should be changed ‘to specify a presumption that any patent litigation settlement between generic and brand firms that do not allow for immediate generic drug entry be viewed as grounds for forfeiture of the generic’s 180-day exclusivity period’. The report authors noted that this may encourage first-filing generics firms to enter because delaying entry means a loss of exclusivity. The authors also suggest creating additional financial incentives to encourage ‘at-risk launching’ by the first generic drug filer and the creation of a Government Accountability Office to examine options.
The previous solution to generic drug parking was the BLOCKING Act that would allow FDA to approve generic drugs from rival competitors who were not the first before the agency if certain conditions were met, however, the report notes that the success of this has been brought into question.
A vote to reauthorize fees was recently passed in the House of Representatives, but it is yet to pass in the Senate .
