Biogen’s pivotal moment: Will the FDA approve the experimental — and controversial — Alzheimer’s-disease drug aducanumab?


U.S. regulators are anticipated to resolve whether or not to approve Biogen’s experimental Alzheimer’s-disease drug a while this week, a call that might ship the firm’s inventory worth hovering or tumbling.

The Food and Drug Administration is anticipated to announce its resolution about aducanumab on or earlier than Monday.

The still-investigational remedy is seen as promising as a result of it will be the first new Alzheimer’s therapy in additional than 20 years after a string of high-profile failures in the class. It can be thought-about controversial given the conflicting medical knowledge shared by the firm over the years and the ensuing blended views of Wall Street analysts and physicians.

“As a scientist, it’s not my inclination to consult a crystal ball, especially for a decision as complex as this one,” Dr. Howard Fillit, chief science officer for the Alzheimer’s Drug Discovery Foundation, advised MarketWatch by way of electronic mail. “While it’s the FDA’s role to make decisions based on science and with the best interests of patients in mind, it’s much harder when the science is ambiguous, as it is here with different outcomes from the two clinical trials.”

There are a lot of potential eventualities for aducanumab.

An approval with a large label may in the end imply billions of {dollars} in new gross sales for Biogen and its growth associate, Tokyo-based Eisai Co. Ltd.

It may very well be a reprieve from income stress for Biogen, which is on the hunt for a brand new flagship product now that its blockbuster multiple-sclerosis drug Tecfidera has misplaced patent safety.

A extra restricted approval may yield a much less dramatic consequence for the inventory and restricted gross sales potential. And a rejection would negatively influence shares of not solely Biogen however probably different biopharmaceutical corporations with vital new potential discoveries in the pipeline.

“We model a 70% chance of approval but relatively modest peak sales — likely in younger and highly motivated patients for whom a 35% reduction in the rate of cognitive disability could extend their active lives,” BTIG analyst Tom Shrader advised buyers this week.

Either method, the resolution may also elevate questions for the thousands and thousands of American households searching for out new therapy choices for family members who’ve been recognized with the neurodegenerative illness. 

“If approved, aducanumab would be just the first weapon in a robust arsenal that tackles the various disease pathways,” Fillit mentioned. “I am confident we will have additional treatment options in the coming years.”

After a number of years of medical ups and downs, buyers have change into considerably cautious of their expectations for aducanumab.

In early 2019, Biogen shared disappointing medical outcomes from two Phase three medical trials for aducanumab and mentioned it will scrap additional growth of the drug consequently. Then, later that 12 months, the company surprised investors when it introduced new knowledge from the identical research that indicated higher efficacy amongst a bigger group of sufferers.

Around that point, Baird analyst Brian Skorney told investors that “there are so many reasons we think aducanumab is getting rejected [that] our word-count restrictions don’t allow us to put them all here.”

Aducanumab, although nonetheless investigational, has weighed closely on Biogen’s inventory for years.

The inventory hit a three-year low of $216.71 on March 22, 2019, round the time the firm mentioned it will cease growing aducanumab, earlier than rebounding with the information that the firm had resurrected the drug. It closed out 2019 at $296.73. Shares closed at $267.15 on Tuesday.

An approval may ship the inventory worth as excessive as $390, and a call towards approval may see it drop to as little as $200, in accordance with Bernstein analysts, in a word this week to buyers.

RBC Capital Markets’ Brian Abrahams has predicted the inventory may transfer up or down by 30%. He urged that an approval for Biogen would bode effectively for different massive drug makers that goal to develop their very own therapies relatively than purchase them in acquisitions of smaller, extra nimble corporations, and it may present additional hints to the pondering at the FDA, which stays leaderless greater than 4 months into the Biden administration.

If aducanumab is accepted, there are nonetheless a lot of industrial unknowns, together with how will probably be priced — one factor to recollect is that the overwhelming majority of individuals with Alzheimer’s are Medicare beneficiaries and not lined solely by industrial well being insurers — and how prepared suppliers will probably be to prescribe a brand new remedy to their sufferers. Further, a slim label may additionally restrict utilization of the drug.

“Biogen will probably price aducanumab high,” Bernstein’s Ronny Gal wrote in a word on Tuesday. “The more we think about it, the more it seems sensible. Biogen has a long history of pricing drugs in the specialty range; Biogen is less likely to fear a backlash.”

The Institute for Clinical and Economic Review, a sort of drug-pricing watchdog, lately mentioned that, because of the comparatively “small overall health gains” demonstrated in the Phase three medical trials, the drug must be priced no greater than $8,400 a 12 months.

That mentioned, industrial plans are already in movement. Biogen expects to spend $600 million on gross sales, normal, and administrative prices in 2021 for aducanumab’s advertising rollout, and it has 600 medical amenities which can be reportedly able to deal with sufferers.

Biogen executives in April advised buyers to anticipate “modest revenue” this 12 months if the remedy is accepted. (RBC estimates the drug may generate $68 million in income in 2021.)

Biogen’s inventory has gained 10.8% thus far this 12 months, whereas the benchmark S&P 500
