On July 12, a process that will take until next year to complete.
The Centers for Medicare & Medicaid Services said it will accept public comments about how Medicare should cover aducanumab through Aug. 11. The agency intends to post a draft decision memo on its coverage approach by Jan. 12, 2022, and then finalize this policy by April 12. Coverage decisions about aducanumab now are being made at the local level by Medicare’s administrative contractors, CMS said in a press release.
The announcement followed separate public calls for such a review by America’s Health Insurance Plans (AHIP) and the Alzheimer’s Association.
On June 30, AHIP submitted a formal request to the CMS. In it, AHIP requests that CMS take “swift action” on a national coverage determination for aducanumab. In the request, the organization specifically urged CMS to use a policy known as coverage with evidence development (CED) for Aduhelm.
This CED approach would allow access for patients considered most likely to benefit from the drug while Biogen continues research needed to definitively show its clinical benefit, said AHIP chief executive Matt Eyles.
In June, the Food and Drug Administration approved aducanumab based on data suggesting the drug might slow AD progression using the surrogate marker of a reduction in amyloid plaque.
The FDA’s accelerated approval letter set a 2030 deadline for Biogen to produce evidence from a phase 3 clinical trial definitively proving the drug’s efficacy.
Hefty price tag
Even if Biogen meets the FDA’s deadline, patients with AD, their families, clinicians, and insurers likely will wrestle for years with questions about whether to use this costly drug without clear evidence of benefit. The drug is estimated to cost $56,000 per year.
In addition, patients taking the drug will be required to undergo MRI scans to monitor for brain swelling or bleeding, complications that were experienced by those participating in previous studies of the drug, Mr. Eyles noted in his letter to CMS, which AHIP provided to this news organization.
About 80% of those eligible for aducanumab in the United States are enrolled in Medicare, write James D. Chambers, PhD, MPharm, Tufts University, Boston, and coauthors in a June article in the journal Health Affairs. Like AHIP, these authors also recommended CMS consider the CED path for the drug.
CMS has used the CED approach since 2003 to evaluate interventions such as amyloid PET for clinical evaluation of AD to implantable cardioverter defibrillators.
Applying CED to aducanumab “would provide the medical community, patients, caregivers, and payers with additional information long before the FDA’s required postapproval studies are completed,” Dr. Chambers and coauthors wrote. “It would also ensure that data on every patient treated would add to the knowledge base about how aducanumab impacts patient outcomes such as cognition, function, and quality of life.”
In the AHIP request to CMS, Mr. Eyles also noted that an independent review organization, the Institute for Clinical and Economic Review, said the evidence from studies done to date on aducanumab is “insufficient” to show a net health benefit for patients with mild cognitive impairment because of AD or mild AD.
At the ICER meeting, which will take place July 15, one of ICER’s expert panels, the California Technology Assessment Forum, said it will further consider all of the available scientific data on aducanumab and vote on a series of questions about its efficacy and value.
ICER’s reports have clout because insurers use its recommendations to help determine how to cover drugs and medical treatments. Among the questions ICER has posted online ahead of the meeting is one about the relative effects of aducanumab plus supportive care versus supportive care alone.
