Leuprolide Plus Cholinesterase Inhibition to Reduce Neurological Decline in Alzheimer's (LUCINDA)

Start: November 27, 2020
End: February 2026
Enrollment: 180

What Is This Study About?

This phase 2 trial will assess the effects of an existing drug, leuprolide acetate (Eligard), in women with Mild Cognitive Impairment or Alzheimer's disease who take a stable dose of donepezil (Aricept). Participants will be randomly assigned to take either the study drug or a placebo as an injection given once every 12 weeks for 48 weeks (total of four injections). Researchers will measure cognitive function and overall function, as well as plasma and neuroimaging biomarkers of Alzheimer's by MRI.
