2 Voucher Program Drug Reviews Delayed: Reuters
FDA has delayed its review of Sanofi’s diabetes drug Tzield (teplizumab-mzwv) and Disc Medicine’s blood disorder medication bitopertin due to safety and efficacy concerns. An exclusive Reuters story says both drugs were being reviewed as part of the new Commissioner’s National Priority Voucher Program, which promised decisions in one to two months for a limited number of drugs that met specified criteria involving public health, national security, domestic manufacturing, or price.
According to Reuters, reviewers cited Tzield adverse event reports, including two related to seizure and blood clotting, and one death. Concerns raised about bitopertin reportedly included trial data and the risk of abuse.
The delays had not been previously reported, Reuters says, and the two companies declined to comment to the news service.
HHS spokesman Andrew Nixon told Reuters that FDA does not comment on applications that are under review and that review divisions are granted flexibility to adjust timelines.
Reuters further reports that reviews of Lilly and Boehringer Ingelheim drugs in the voucher program are taking longer than planned.
Drug review experts contacted by the news service said the delays are reassuring since the promised one- to two-month review time led to questions about how rigorous the reviews would be.
“It is a very good sign [that] FDA in this program is willing to say, ‘Hold on, we’re not actually sure this product should be allowed on the market,’” said University of Pennsylvania health policy professor Holly Lynch. The report says Lynch and others said they still have concerns about the voucher program politicizing drug reviews since the Trump administration is selecting the drugs to be included, and final approval rests with a panel of senior FDA officials rather than staff reviewers.
