L'annuncio di Biogen's sul New York Times che invita il lettore a fare un 'Quiz dei sintomi'.
Biogen and the FDA found a way to stir a tempest of controversy and dismay over the accelerated approval of an unproven Alzheimer’s drug. But the big biotech is plowing straight ahead into the maelstrom with a well-prepared kickoff of an advertising campaign aimed at sparking patient interest in a drug that a growing lineup of healthcare institutions are refusing to administer. Biogen and Eisai have started running a slick campaign to focus attention on mild cognitive impairment, featuring an elderly couple — Jim and Jane — now confronting the disease. That comes with a handy “symptoms quiz” on forgetfulness — how often do you forget stuff? — and a stat that 1 in 12 Americans over 50 suffer from MCI. You can also find a specialist for Alzheimer’s, if you feel the need. These campaigns are standard in the marketing field. Get more people asking for diagnostic tests, you get more candidates asking for your drug. And right now, Biogen’s Aduhelm is it in terms of claiming to help disease progression, as opposed to symptomatic relief. Forget, for a moment, the vitriolic response in the industry, among experts in the field and the skeptical stance of many payers focused on a drug priced at a stunning $56,000 — a cost largely to be born by Medicare, which is now setting out to establish the terms under which it will cover the drug. Left unrestricted, Baird’s Brian Skorney has estimated annual revenue could hit $60 billion — well over the $42 billion NIH spends on medical research every year. But that’s also unlikely. Tim Anderson, a respected analyst at Wolfe, has been watching the Alzheimer’s R&D field for years and years. Early on, he used to compare the R&D contenders here as players in search of the ever elusive golden ticket awaiting anyone who could win an OK on a drug approved for millions of desperate patients. Up until now, though, he’s never set out a peak sales figure for an Alzheimer’s drug, as they were just too risky to be believed. The FDA approval of Aduhelm (aducanumab), though, changed all that. Doing some back-of-the-envelope figuring, Anderson calculates now that Biogen should be able to count on $10.6 billion in sales in 2024. That would make it a mega-maker like Humira. But after that, he sees the total declining. Why is that? Looking past the furor, Anderson sees an open highway for Eli Lilly and Roche to barrel down the lane to their own mega-market opportunities, now that the FDA has set a precedent in using amyloid clearance as the marker for an accelerated approval. So now with breakthrough drug designations for both, he sees a quick turn to the big time. Lilly, he figures, can pivot straight to blockbuster status with breakthrough tag in place and a possible approval next year — setting the stage for $5.9 billion in peak performance in 2025. Roche’s frequently-failed gantenerumab, meanwhile, can go on to a peak sales figure of $8.7 billion in 2027 after hunting an OK — and instant blockbuster status — with an approval 2 years out. And that’s the drug he expects to stay on top for awhile. Add it up and you have a brand new market in search of around $25 billion in peak sales potential. Even as the debate over whether or not the amyloid theory should be taken seriously as a path to meaningful improvements for Alzheimer’s, or is an also-ran with virtually no clear data to prove that any of these drugs actually work — or just influences a marker that may not be predictive of disease. Even at these more conservative numbers, it’s not hard to see why the long marathon toward what had appeared to be an ever-receding mirage has turned into a sprint to the finish line. | Biogen e la FDA hanno trovato un modo per innescare una tempesta di polemiche e sgomento per l'approvazione accelerata di un farmaco non provato per il morbo di Alzheimer (MA). Ma la Big Biotech sta arando dritta nel turbine con una partenza ben preparata della campagna pubblicitaria volta a sprigionare interesse dei pazienti per un farmaco che sempre più istituzioni sanitarie rifiutano di dare.
