Eisai introduced results late Tuesday from a world study of practically 1,800 individuals with early-stage Alzheimer’s.
The drugmaker stated early results confirmed that its therapy, lecanemab, decreased affected person scientific decline by 27% when in comparison with a placebo or faux drug after 18 months of the infused therapy. Patients had been monitored utilizing a scale that measures how they do in areas like reminiscence, judgement, downside fixing and personal care.

Last year, Biogen’s Aduhelm grew to become the primary new Alzheimer’s drug launched in practically 20 years. But it has largely flopped after debuting with a price ticket of $56,000 yearly, which Biogen later slashed.

Like Aduhelm, lecanemab, which Eisai developed and ran by scientific trials, seeks to take away a protein referred to as beta-amyloid from the brain.
But Eisai executives say lecanemab focuses extra on floating clumps of the protein earlier than it kinds a plaque, which is what Aduhelm targets.
Eli Lilly and Co. is also creating a possible therapy, donanemab, that helps clear the protein.
