The 18-month investigation by two House committees detailed “atypical collaboration” between FDA regulators and an organization it’s alleged to oversee — Aduhelm producer Biogen. The probe additionally cited Biogen paperwork saying the corporate meant to “make history” when it set what investigators referred to as an “unjustifiably high” preliminary worth of $56,000 a 12 months for the drug.

The FDA and Biogen issued statements Thursday defending the Aduhelm approval course of.

In 2021, the FDA overruled its personal unbiased scientific advisors when it accredited Aduhelm regardless that analysis research did not show the drug actually helped sufferers.

The investigators really helpful that the FDA take steps to revive belief within the approval course of that embrace correctly documenting interactions with drugmakers. They additionally urged producers to take note of recommendation from affected person teams and different outdoors specialists on truthful drug pricing.

In an announcement Thursday, the FDA stated the Aduhelm determination “was based on our scientific evaluation of the data” and that the company’s inside evaluation discovered its interactions with Biogen have been acceptable. But it stated it plans to replace steerage on Alzheimer’s drug growth and can evaluation the investigation’s findings.

In its personal assertion, Biogen stated: “Alzheimer’s is a highly complex disease and we have learned from the development and launch of Aduhelm” however that it “stands by the integrity of the actions we have taken.”
