2. Has a body weight = 50 kg
3. Has a diagnosis of Probable AD Dementia or MCI due to AD in accordance with NIA AA Working Group Criteria
4. Has a biomarker profile reflecting AD, accord. to the NIA-AA Research Framework defined as follows
a) Positive amyloid PET scan on file prior to Screening OR
b) CSF AD biomarker result using Lumipulse (Fujirebio) assay at Screening with:
i. Aß-42/Aß-40 ratio < 0.61 AND
ii. p-tau > 61 ng/L OR
iii. if p-tau181 concentration=50 to 61ng/L, ratio of p-tau/Aß-42 > 0.11 OR
c) CSF AD biomarker result on file within 12 months prior to Screening that is positive for Aß-42 (below the cut-off) AND p-tau (above the cut-off) OR a p-tau181/Aß-42 ratio above the cut-off for that assay (amyloid AND p-tau positive)
Note1: Subjects without a prior CSF result must provide a new CSF sample at the Scr–Part 2 V
Note2: Subjects with a prior positive CSF result (allowing study enrollment) must provide 2 to 3 aliquots of CSF from their prior diagnostic assessment; and the prior CSF result must be recorded
5. Be willing to undergo LP for CSF testing accord. to Schedule of Assessments
6. Has one of the following apolipoprotein E (APOE) genotypes– either APOE4/4 or APOE3/4
Note: For subjects with a prior (historical) APOE genotype blood test, the test result must be provided and recorded in CRF
7. Has an MMSE score at Screening of 22 to 30 inclusive (> 26 for MCI; 22 to 26 for Mild AD)
8. Has a CDR Global Score at Screening of 0.5 (MCI, Mild AD) or 1 (Mild AD) and a CDR Memory Box Score of = 0.5

10. Be willing to sign an IRB/ IEC approved ICF indicating that he/she understands the purpose of the study and the procedures that are required for study, and that he/she is willing to participate in study. Subjects are free to withdraw consent at any time. If a subject is unable or deemed not competent to sign the consent form the subject’s legally authorized representative may sign consent form with subject’s assent, except where local regulations and IRB/IEC approval does not allow subjects who are unable or deemed not competent to sign consent form, to participate in study
Note: Subjects who participate in PK Profile Substudy for extended PK sampling will sign an additional consent form specific for the substudy
11. Can complete the cognitive testing procedures Corrected visual and auditory acuity must be adequate to comply with protocol
12. Lives at home independently, in a senior living facility, or in an assisted living facility
