Summary

This trial will study whether the U.S.A marketed generic anti-viral drug Valtrex (valacyclovir, 500mg oral tablet) can be repurposed to treat Alzheimer's disease.

Who is the study for?
This trial is for mild Alzheimer's patients who test positive for herpes simplex virus. They must be able to consent, have a caregiver, and not have severe medical conditions or other major neurological disorders. Participants should not have had significant radiation exposure in the last year or take high doses of benzodiazepines.
What is being tested?
The study tests if Valacyclovir (an anti-viral drug) at 4 grams per day can treat Alzheimer's disease compared to a placebo over 18 months. It involves 130 participants with mild AD, split into two groups by chance, one receiving the drug and the other a placebo.
What are the potential side effects?
Valacyclovir may cause side effects like headache, nausea, stomach pain, vomiting, dizziness. Rarely it might lead to serious issues such as kidney problems or increased risk of bleeding.
