The U.S. Food and Drug Administration’s (FDA) support process of the controversial and costly new Alzheimer’s drug Aduhelm was “rife with irregularities” and “highly atypical,” according to a report released connected Dec. 29 by the House Oversight and Energy and Commerce committees.
The study (pdf) is the effect of an 18-month probe conducted by the Committee connected Oversight and Reform, and Committee connected Energy and Commerce into the regulatory reappraisal and approval, pricing, and selling of the Massachusetts-headquartered biotechnology institution Biogen Inc.’s Alzheimer’s illness drug, aducanumab, which is wide known by the sanction Aduhelm.
Aduhelm was granted accelerated support by the FDA successful June 2021 after data from objective trials showed a simplification successful the amyloid-beta plaques of the brain, which “is expected to pb to a simplification successful the objective diminution of this devastating signifier of dementia.”
Experts judge encephalon plaques could beryllium a contributor to Alzheimer’s.
However, the study published connected Thursday noted that the support came contempt the information that “Biogen canceled objective trials for Aduhelm successful March 2019 owed to an autarkic study indicating the cause was improbable to efficaciously dilatory cognitive and functional impairment and that further objective survey would beryllium futile.”
An extracurricular advisory committee of experts besides recommended against approving the drug, the study noted.
Medicare Restricts Coverage of Aduhelm
The Medicare programme has restricted sum of Aduhelm, proposing alternatively that it only beryllium utilized successful objective trials, which has led to severely constricted usage of the Biogen drug.
Specifically, the study states that the FDA’s Interactions with Biogen were “atypical” and that the bureau failed to travel its ain protocol.
“Documents obtained by the Committees amusement that FDA unit and Biogen engaged successful astatine slightest 115 meetings, calls, and substantive email exchanges implicit a 12-month play opening successful July 2019. These exchanges included astatine slightest 40 FDA-Biogen ‘working group’ meetings. FDA’s ain interior reappraisal of the agency’s support process for Aduhelm recovered that the grade of collaboration betwixt FDA and Biogen was atypical and ‘exceeded the norm successful immoderate respects,'” the study states.
“FDA confirmed that the full fig of meetings betwixt FDA unit and Biogen during this clip is chartless due to the fact that FDA lacked a ‘clear record’ of the informal meetings and different interactions betwixt bureau unit and Biogen,” the study notes, adding that of the much than 40 meetings held betwixt the FDA and biogen, “not each were decently documented according to interior FDA procedures.”
FDA ‘Abruptly Changed Course and Granted Approval’
An additional 66 calls and substantive email exchanges betwixt the bureau and the institution were besides not documented, according to the report.
Elsewhere, the Committees said that FDA AND Biogen “inappropriately collaborated” for respective months connected a associated briefing papers for the advisory committee’s reappraisal that didn’t adequately bespeak differing views astir the cause wrong FDA.
“For example, successful an speech of the draught briefing papers connected October 9, 2020, FDA unit asked Biogen to determination a paragraph drafted by the bureau into Biogen’s conception of the memorandum—a alteration reflected erstwhile the papers was finalized,” the study states. “FDA’s interior reappraisal determined that the Office of Neuroscience (ON) wrong CDER’s Office of New Drugs (OND) had failed to get interior OND statement connected FDA’s presumption anterior to moving with Biogen connected the document.”
After considering Aduhelm nether the accepted support pathway for 9 months, the probe besides recovered that the FDA “abruptly changed people and granted support nether the accelerated support pathway—which allows the usage of surrogate objective endpoints to show effectiveness—after conscionable 3 weeks of review.”
Finally, the study states that Biogen initially acceptable an “unjustifiably high” terms of $56,000 per twelvemonth for Aduhelm successful an effort to “make history” contempt a deficiency of demonstrated objective payment and the anticipated fiscal interaction connected patients and the Medicare program.
Report ‘Raises Serious Concerns About FDA’s Lapses successful Protocol’
“The findings successful this study rise superior concerns astir FDA’s lapses successful protocol and Biogen’s disregard of efficacy and entree successful the support process for Aduhelm,” the study concludes.
The committees recommended a fig of steps beryllium taken “help reconstruct the American people’s trust” successful the agency’s regulatory reviews, including ensuring that each substantive FDA interactions with cause companies are decently documented.
In a connection responding to the report, the FDA said its decision to o.k. Aduhelm was based connected technological valuation of the information contained successful the application.
“It is the agency’s occupation to often interact with companies successful bid to guarantee that we person capable accusation to pass our regulatory decision-making. We volition proceed to bash so, arsenic it is successful the champion involvement of patients,” the spokesperson said.
The bureau will continue to usage the accelerated support pathway whenever due but has already begun implementing immoderate of the recommendations successful the report, the spokesperson added.
Biogen said successful a connection that it “stands by the integrity of the actions we person taken.”
