Summary
This early-stage study tests a new drug called LY3954068 in 48 people with mild Alzheimer's symptoms. The drug is given directly into the spinal fluid, either once or twice, to see if it is safe and how it affects Alzheimer's markers. The study lasts up to 100 weeks and includes a placebo group.

Inclusion Criteria: * Have a body mass index (BMI) within the range 18 to 40 kilograms per square meter (kg/m²), inclusive, at screening. * Have gradual and progressive change in memory function for greater than or equal to (≥) 6 months as reported by the participant or informant. * Have a mini mental state examination (MMSE) score of 18 to 30 at screening. * Have a clinical dementia rating (CDR) global score of 0.5 to 1.0, with a memory box score ≥ 0.5 at screening. * Meet flortaucipir F18 positron emission tomography (PET) criteria, as defined in the TAUVID™ FDA label (TAUVID™ prescribing information, 2024), demonstrating evidence of tau pathology. * Males who agree to follow contraceptive requirements, or women not of childbearing potential (WNOCBP). * Participants must have up to 2 study partners who are with contact with the participant at least 10 hours per week and one of whom can attend study appointments. Exclusion Criteria: * Has current serious or unstable illnesses including cardiovascular, hepatic, renal, gastroenterological, respiratory, endocrinologic, neurologic (other than Alzheimer's Disease), psychiatric, immunologic, or hematologic disease and other conditions that, in the investigator's opinion, could interfere with the analyses in this study; or has a life expectancy of less than (\<)24 months. * Have a sensitivity to flortaucipir F18. * Have contraindication to magnetic resonance imaging (MRI), including claustrophobia or the presence of contraindicated metal (ferromagnetic) implants/cardiac pacemaker. * Have a current exposure to an amyloid targeted therapy (ATT). Prior exposure to ATTs greater than 1 year from the last dose may be permitted at the discretion of the investigator and in consultation with the sponsor. * Have previous exposure to any Investigational Medicinal Product administered intrathecal (IT) or previous exposure to any anti-tau therapy. * Have a history of clinically significant back pain, back pathology and/or back injury (for example, degenerative disease, spinal deformity or spinal surgery) that may predispose to complications or technical difficulty with lumbar puncture.
