Kesselheim referred to as it “in all probability the worst drug approval determination in current U.S. historical past” in a scathing resignation letter he despatched to performing FDA Commissioner Janet Woodcock on Thursday.
“It’s clear to me that FDA is just not presently able to adequately integrating the Committee’s scientific suggestions into its approval choices,” wrote Kesselheim, who had served on the FDA advisory committee since 2015.
He mentioned the FDA switched its strategy to Aduhelm on the final minute to grant accelerated approval — a classification that may require the drug’s makers to conduct one other research after it’s launched to the general public. And he alleged that when the advisory committee voted towards the drug in November, its members had been given totally different standards to think about than the FDA cited in an evidence of its determination.

“This drug has generated every kind of pleasure as a result of it’s the first permitted drug that does extra than simply relieve the signs of Alzheimer’s. This drug truly impacts an underlying illness course of by decreasing the quantity of sticky amyloid plaque that builds up within the mind. The catch is that eradicating this plaque might not truly assist sufferers keep away from reminiscence loss and pondering issues. One large research confirmed that it did. One other confirmed that it did not.”
He famous that the FDA wouldn’t usually be anticipated to grant approval to a drug underneath the combo of circumstances which have surrounded Aduhelm.
Drawing connections to a different costly drug
In his resignation letter, Kesselheim additionally cited the FDA’s approval in late 2016 of eteplirsen, which is supposed to deal with Duchenne muscular dystrophy. The company’s strategy to the 2 medicine has been a debacle, the physician mentioned.
Sarepta, the maker of eteplirsen, mentioned on the time that it might cost $300,000 per 12 months for every affected person receiving the drug.
The approval of “two extremely problematic medicine” that may not assist people who find themselves affected by horrible circumstances, Kesselheim warned, “will undermine the care of those sufferers, public belief within the FDA, the pursuit of helpful therapeutic innovation, and the affordability of the well being care system.”

In protection of that top value, Biogen and Eisai level to the massive quantities of cash required to handle somebody with Alzheimer’s illness. Annually within the U.S., they mentioned, Alzheimer’s and different dementias carry an total annual value of greater than $600 billion.
