A Donanemab (LY3002813) Study in Participants With Preclinical Alzheimer's Disease (TRAILBLAZER-ALZ 3)
- Registration Number
- NCT05026866
- Lead Sponsor
- Eli Lilly and Company
- Brief Summary
The main purpose of this study is to evaluate the safety and efficacy of donanemab in participants with preclinical Alzheimer's Disease (AD). Approximately 800 additional participants will be enrolled in a 12-month addendum to assess safety of a different titration regimen.

- Has a reliable study partner and backup study partner familiar with overall function and behavior, such as day-to-day activities and cognitive abilities.
- Have adequate literacy, vision, and hearing for neuropsychological testing at screening.
- Contraceptive use by men or women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies
- Female participants include those who are infertile due to surgical sterilization (hysterectomy, bilateral oophorectomy, or tubal ligation), congenital anomaly such as Mullerian agenesis; or post menopausal (women 55 or older not on hormone therapy and had at least 12 months of spontaneous amenorrhea; or with a diagnosis of menopause prior to starting hormone replacement therapy.
- Mild cognitive impairment or dementia, or significant other neurodegenerative disease that can affect cognition.
