there was no specific approval date for Eli Lilly's Alzheimer's treatment, donanemab. Clinical trials and the FDA approval process can take several years, and timelines may vary based on the data submitted by the pharmaceutical company and the FDA's review process.
Since my information is not up-to-date, I recommend checking the latest news from reputable sources or visiting the official FDA website for the most current information on the status of donanemab or any other drug approvals. The FDA usually provides updates and announcements related to drug approvals and regulatory decisions on its website.
