•Male and female participants ≥ 50 years of age.
•Females must be of non-childbearing potential, defined as:
•Postmenopausal females must have had ≥12 months of spontaneous amenorrhea (with documented follicle-stimulating hormone (FSH) ≥40 milli international units (mIU)/mL) or
•Surgically sterile including those who have had a hysterectomy, bilateral oophorectomy, bilateral salpingectomy or bilateral tubal ligation at least 6 months before the first dose of the study drug.
•Body mass index (BMI) between 18 and 32 kg/m2 (inclusive), and weighs ≥54 kg.
•Screening vital signs (measured after participants have rested in a supine position for a minimum of 5 minutes) within the following ranges: heart rate: 40-100 beats per minute (bpm); systolic blood pressure (BP): 90-150 millimeter of mercury (mmHg); diastolic BP: 50-95 mmHg. Out-of-range vital signs may be repeated once at any time point during the study per Investigator discretion.
•Sperm-producing males in a sexual relationship with females of childbearing potential (FOCBPs) must use adequate contraception (e.g., condom) and must not donate sperm, starting from Screening until 180 days after the last dose of the study drug (See Section 5.3).
•Must be willing to abstain from smoking while confined at the CTU.
•The participant is confirmed to have adequate venous access by study staff.
•Is willing and able to remain in the CTU for the entire duration of each confinement period and return for outpatient visits.

•Shows signs/symptoms of dementia or has a parent with a known autosomal dominant mutation causing familial AD.
•A clinically significant abnormal finding on the physical exam, medical history, clinical laboratory results or electrocardiogram (ECG), or at Screening. The Investigator may repeat clinical laboratory tests once to assess any out-of-range values for clinical significance.
•Participants with a value >2.5 times the upper limit of normal (ULN) or <60% the lower limit of normal (LLN) or any other value of concern per the Investigator will be excluded.
•QT corrected for heart rate by Fridericia's cube root formula (QTcF) interval is >460ms in females, QTcF>450ms in males and has ECG findings considered normal or not clinically significant by the Investigator or designee at Screening.
•Suicide risk, as determined by meeting any of the following criteria:
•Any suicide attempt or preparatory acts/behavior on the Columbia-Suicide Severity Rating Scale (C-SSRS) Baseline/Screening in the last six months.
•Suicidal ideation in the last six months as defined by a positive response to Question 5 (Suicidal Ideation) on the C-SSRS Baseline/Screening.
•Significant risk of suicide, as judged by the site Investigator.
•Known allergy to biological products or known hypersensitivity to any component of sabirnetug or hyaluronidase, including excipients.
•Use of any experimental agent within 6 months of the first dose of study drug.

•Use of any prescription medication, starting from 14 days or 5 half-lives (whichever is longer) prior to the first dose of the study drug until EOS without evaluation and approval by the Investigator.
•Blood or plasma donation within 7 days before the first dose of the study drug until EOS. Blood/plasma donations should not be made for at least 90 days after the last dose of the study drug.
•Has any prior history of substance abuse or treatment (including alcohol) within the 2 years prior to the first study treatment administration.
•Regular alcohol consumption >14 units per week (1 unit=½ pint beer, 25 mL of 40% spirit or a 125-mL glass of wine).
•Has a positive urine screen for drugs of abuse (amphetamines, barbiturates, benzodiazepines, cocaine, cannabinoids, opiates), cotinine, or alcohol.
•Has a positive test for hepatitis B surface antigen, hepatitis C antibody, or human immunodeficiency virus (HIV) at screening or has been previously treated for hepatitis B, hepatitis C, or HIV infection.
