The analysis highlighted that ADUHELM significantly reduced tau pathology, a defining feature of Alzheimer's disease, as measured by plasma p-tau181, when compared to placebo. The effect was greater with higher doses and longer duration of ADUHELM treatment. Greater reduction in plasma p-tau181 also had a statistically significant correlation with less decline in cognition and function in ADUHELM-treated patients. Furthermore, the analysis demonstrated a statistically significant correlation between change in plasma p-tau181 and lowering of amyloid beta plaque, showing the effect of ADUHELM on the two core pathological features of Alzheimer's disease.
'We now have robust and concordant data that ADUHELM has effect on two core defining pathologies of Alzheimer's disease, and substantial evidence of treatment correlation between changes in plasma p-tau181 and the slowing of disease progression,' said
The findings showed that ADUHELM significantly lowered plasma p-tau181 in a dose- and time-dependent manner vs. placebo in both Phase 3 trials. In the EMERGE high-dose group, p-tau decreased 13% from baseline (p
