Study Summary

This trial will have two parts. In the first part, 180 people will take either a placebo or one of three different doses of the drug being studied. This will go on for at least 24 weeks. The second part, which will only happen if the first part shows promise, will involve 414 people taking the drug or a placebo for a longer period of time to see if it improves cognitive function and has other benefits.

Eligibility Criteria

Age 50 - 89 · All Participants · 9 Total Inclusion Criteria

Mark “Yes” if the following statements are true for you:
Individuals aged 50 to 89 (inclusive) at screening were included in the study.
Having been diagnosed with Mild Cognitive Impairment (MCI) due to Alzheimer's disease (AD) or Mild probable AD based on the workgroups of the Diagnostic Guidelines of the National Institute on Aging and Alzheimer's Association (NIA-AA).
indicates a high probability of cognitive impairment A mini-mental state examination score of 20-30 is indicative of a high likelihood of cognitive impairment.
The person has a low score on the Montreal Cognitive Assessment test.
The individual has some cognitive impairment, but it is not severe enough to be clinically diagnosed with dementia.
The study partner must be someone who interacts with the participant frequently (approximately >3-4 times per week), is willing to attend all clinic visits, and can help the participant follow study procedures.
predicts better clinical outcome in early MS The study found that a positive CSF AD biomarker signature was predictive of a better clinical outcome in early MS.
(AD) was found in 8% of participants who were clinically diagnosed with mild cognitive impairment (MCI) and in 24% of those with AD
