At its November meeting, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) voted against Biogen's controversial Alzheimer's drug aducanumab (Aduhelm), making it highly unlikely the drug will be recommended for approval at its December meeting.
In a news release issued today, Biogen said the company received a "negative trend vote" on the aducanumab marketing authorization application in Europe.
"While we are disappointed with the trend vote, we strongly believe in the strength of our data and that aducanumab has the potential to make a positive and meaningful difference for people and families affected by Alzheimer's disease [AD]," Priya Singhal, MD, MPH, head of global safety and regulatory sciences and interim head of research and development at Biogen, said in the release.
The EMA committee is expected to adopt a formal opinion on the marketing application at its December meeting (December 13-16, 2021).
"Biogen will continue to engage with the EMA and CHMP as it considers next steps towards the goal of providing access to aducanumab to patients in Europe," the company said.
At the recent Clinical Trials on Alzheimer’s Disease conference, Biogen announced new phase 3 findings that "provide further evidence of aducanumab's effect on lowering amyloid beta plaque and downstream tau pathology, the two defining pathologies of Alzheimer's disease," the company said.
No Clinically Meaningful Effect
In a statement from the nonprofit UK Science Media Centre, Prof Robert Howard, from University College London, said the result of the CHMP vote "is absolutely the decision that we should have expected from the EMA's expert advisory panel and is consistent with the FDA's [US Food and drug Administration's] Advisory Committee who voted unanimously 12 months ago against approval of aducanumab because of a lack of demonstrable efficacy in the pivotal phase 3 trials ENGAGE and EMERGE."
"The FDA's accelerated approval of aducanumab, solely on the grounds that it was reasonable to expect that reduction in amyloid would lead to improvement in the course of Alzheimer's disease, despite all the evidence indicating no meaningful correlation between amyloid reduction and symptom improvement, has been highly controversial and has called into question the impartiality of the FDA and its staff," Howard noted.
He anticipates that when the EMA panel meets in December they will not grant a license to aducanumab.
"Aducanumab is a treatment without convincing efficacy, with serious associated adverse effects and a high financial cost. On the basis of the available evidence and in the best interests of people with Alzheimer's disease, their families and those who care for them, EMA and MHRA [Medicines and Healthcare products Regulatory Agency] should not approve a license for aducanumab," Howard said.
Also weighing in, David Thomas, Head of Policy at Alzheimer's Research UK, said the need for new AD treatments is "urgent," but added that "it's vital that regulators judge that any new treatment is safe and effective."
"Results of aducanumab's phase 3 trials, EMERGE and ENGAGE, have sparked much debate among the research community about how to judge the effectiveness of any new Alzheimer's treatment," Thomas noted.
"The FDA's approval of aducanumab in the US was based on the drug's ability to clear the hallmark Alzheimer's protein amyloid from the brain. As part of this approval the regulator now requires further trials to be carried out to ensure that aducanumab brings long-term improvement to people's memory, thinking and day-to-day lives," Thomas said.
EMA is now undertaking its own review of the data and "it's important that we wait for the committee's official recommendation, which is expected next month. In the meantime, we must continue to work at pace to ensure researchers are developing a broad pipeline of potential new treatments for diseases like Alzheimer's, and that health systems like the NHS [National Health Service] will be ready to deliver them in the years ahead," he added.
"Reckless" FDA Decision
In related news, the Centers for Medicare and Medicaid Services (CMS) has announced that the Medicare Part B standard premium would rise to $170 per month for all enrollees, a 15% spike over the 2021 premium level.
"All Part B Medicare beneficiaries soon will be forced to bear significant financial burden as a direct result of the FDA's reckless decision to approve aducanumab, a drug that has not been proven to provide any clinically meaningful benefit to Alzheimer's patients but nevertheless carries an indefensible annual price tag set by Biogen at $56,000 per year for just the drug alone," Michael Carome, MD, director of Public Citizen’s Health Research Group, said in a statement.
"To protect the many Medicare beneficiaries who cannot afford the unacceptable 15% jump in Part B premiums, CMS must promptly announce that it will exclude aducanumab from coverage under the Medicare program until there is definitive evidence that the drug provides substantial evidence of cognitive benefit to Alzheimer's disease patients," Carome said.
