Studying CpG1018 for Early Alzheimer's Disease

This study is testing a drug called CpG1018 in people with mild cognitive impairment (MCI) due to Alzheimer's disease or mild Alzheimer's dementia. CpG1018 is given as a shot under the skin. Researchers want to see if CpG1018 is safe and how well people tolerate it. You might be able to join if you are 60 to 85 years old, have MCI or mild Alzheimer's, and have a positive amyloid PET scan (a brain scan that looks for signs of Alzheimer's). The study will measure side effects and check for certain markers in your blood. The current status of this study is unclear.

Study design
This is a double-blind, placebo-controlled study, meaning neither you nor your doctor will know if you are receiving the study drug or a placebo (an inactive substance). It plans to include 39 participants across three different dose levels.
What's involved
You would receive subcutaneous injections (shots under the skin) of either CpG1018 or a placebo for 8 weeks. Safety will be monitored for up to 18 weeks.
Compensation
Not stated in the trial record.
Follow-up
Your safety will be monitored for up to 18 weeks after starting the study treatment.
