Pathways & Standards
Approval Standards
When the agency decided biosimilarity standards would be high, it likely ensured the interchangeability designation eventually would become unnecessary.
New US FDA draft guidance attempts to address sponsor confusion about the different types of regulatory meetings under PDUFA, as well as frequently asked questions on nonclinical testing, CMC, pharm/tox and clinical studies.
In the second part of the Pink Sheet’s interview with the former senior FDA official, Woodcock says her push to create a rare disease drug approval pathway that wouldn’t require a randomized controlled trial will not return the agency to “an anecdote standard” or cause a downward creep in the evidentiary standard for approval.
The former CDER Director spoke to the Pink Sheet about why a new statutory standard is needed for certain rare disease drug approvals. We lay out some of her thinking in part one of a multi-part series on the topic.
Review Pathways
The European Medicines Agency wants to discourage drug companies from submitting marketing applications with very interim data cuts and then expecting they can supplement their application with more data later on by requesting for extended clock-stops.
The FDA said the antibody-drug conjugate looks more promising in a subgroup of EGFR mutated lung cancer patients, which caused AstraZeneca to refile the application.
While many companies demonstrated an interest in the UK’s licensing and access pathway for innovative medicines, few made use of the various benefits the scheme had to offer, the MHRA said.
Japan has implemented a streamlined regulatory system designed to enable speedier approvals of selected drugs for designated categories of infectious diseases, which does not require Japanese clinical data.
User Fees
Expected HHS Secretary nominee Robert F. Kennedy Jr.'s dislike of user fees and interest in major FDA reforms could come to a head in the 2027 PDUFA reauthorization.
The FDA’s Peter Marks warned novel approvals will suffer if the agency is forced to spend its time relitigating vaccines. At the top HHS post Kennedy could impact pharma from basic research funding to drug pricing.
Another record-breaking year for novel approvals looks out of reach, but the six novel agents with November goal dates show the continued strength of rare disease drug development.
The number of standard and priority reviews also decreased significantly in FY 2023 compared to the previous year, which caused the fee for redeeming a voucher to rise.
