    .

    In addition, AADvac1 significantly reduced the accumulation of nerve fiber light chain (NfL)
    .

    NfL is an important biomarker of neurodegeneration, and AADvac1 reduces the level of NfL in the blood by 58% (P=0.
    004)
    .

    In the subgroup of AD patients confirmed by AD biomarkers amyloid deposition and tau protein aggregation, AADvac1, compared with placebo, delayed the clinical decline detected by CDR-SB by 27% (p=0.
    048), and will pass The functional deterioration of ADCS-MCI-ADL detection was delayed by 30% (p=0.
