In one-year up­date, Alzheon goes big talk, but shows off lit­tle clin­i­cal da­ta

As Bio­gen pulls its glob­al Aduhelm ap­pli­ca­tions left and right, Alzheon — an­oth­er small­er Mass­a­chu­setts-based biotech — claims (again) it has “in­dus­try-lead­ing” da­ta on its Alzheimer’s drug. In a field lit­tered with drug fail­ures, any clin­i­cal ben­e­fit would be a ma­jor break­through. But on that front, Alzheon came up emp­ty-hand­ed.

In a one-year up­date on its Phase II tri­al, Alzheon said that in 75 pa­tients who took its oral drug ALZ-801 twice a day, it ob­served a 41% re­duc­tion from base­line in lev­els of phos­pho­ry­lat­ed tau, or p-tau, a brain pro­tein which builds up in Alzheimer’s dis­ease. Alzheon al­so said that its drug re­duced the ra­tio of p-tau and a com­po­nent of amy­loid plaques, Aβ42, by 37%.
