How might the CMS decision on Biogen’s Aduhelm impact other Alzheimer’s candidates?

Regardless of the Facilities for Medicare & Medicaid Providers’ (CMS) determination on April 7 to severely restrict protection of Biogen’s (NASDAQ:BIIB) Aduhelm (aducanumab) for Alzheimer’s illness, different drugmakers are forging forward with their candidates for the situation.

On Friday, Eisai (OTCPK:ESALY) mentioned it expects to complete a rolling submission for a Biologics License Utility (BLA) for lecanemab to the U.S. FDA beneath the accelerated approval pathway in Q1 fiscal 2022 (started April 1, 2022).

Eli Lilly (NYSE:LLY) is growing donanemab and in addition mentioned Friday it’s urgent forward with its rolling utility, which it expects to finish by the top of the 12 months, Reuters reported. Nonetheless, the drugmaker will not have part 3 knowledge obtainable till mid-2023.

Roche (OTCQX:RHHBY) is predicted to launch late-stage knowledge on its candidate, gantenerumab, by the top of the 12 months, although it isn’t pursuing accelerated approval.

The CMS determination covers FDA-approved monoclonal antibodies that concentrate on amyloid protein utilizing its discount from the mind as a surrogate endpoint that’s “moderately more likely to predict scientific profit,” however solely in scientific trials.

That might depart Eisai (OTCPK:ESALF), Lilly (LLY), and Roche (OTCQX:RHHBY), like Biogen (BIIB) with Aduhelm, in precarious positions contemplating their candidates additionally goal amyloid plaque discount beneath the speculation that eradicating amyloid slows cognitive decline. The issue is that researchers nonetheless aren’t sure that that is the case.

One potential vivid spot within the CMS determination is that the company mentioned it could cowl authorised antibodies based mostly on direct scientific profit — corresponding to proof of slowing cognitive decline — in CMS-approved potential comparative research. Though the efficacy bar is considerably larger, this might profit drugmakers as CMS famous research designs for these trials are much less rigorous.

Such a research may embody knowledge generated from routine scientific observe or a registry. “Registry knowledge might then be used to evaluate whether or not outcomes seen in rigorously managed scientific trials are reproduced in real-world use and in a broader vary of affected person teams,” CMS wrote.

That might in the end open the door to broader protection determinations for different Alzheimer’s medication, and income from them to drugmakers. However to ensure that this to occur, pharmaceutical firms must present their medication result in a significant slowing down of cognitive decline, one thing no therapy has but to obviously reveal.
