Trial Summary

What is the purpose of this trial?

Anti-viral treatment in Mild Cognitive Impairment (MCI) is a Phase II, placebo-controlled, 52-week trial using oral valacyclovir 4 g/day in 50 HSV seropositive, AD biomarker-positive, amnestic mild cognitive impairment (MCI) patients (eMCI and lMCI). The trial will directly address the long-standing viral etiology hypothesis of Alzheimer's disease (AD) which posits that viruses, particularly the very common herpes simplex virus-1 (HSV1) and herpes simplex virus-2 (HSV2), may be etiologic or contribute to the pathology of AD. This trial will intervene at an earlier stage (MCI). We will compare the repurposed drug valacyclovir to placebo in patients with amnestic MCI (eMCI and lMCI) in a randomized, double-blind, two-arm parallel group 52-week pilot trial. Our Phase II trial will be the first antiviral drug trial conducted in MCI.

Treatment Details

Interventions

• Valacyclovir

Trial Overview The study tests Valacyclovir (an antiviral medication) against a placebo in individuals with Mild Cognitive Impairment to see if it affects the progression of cognitive issues related to Alzheimer's disease. It's a double-blind trial where neither participants nor researchers know who gets the real medicine versus the sugar pill during the year-long study.

Participant Groups

Group I: Valacyclovir Active Control 1 Intervention

Oral valacyclovir will be distributed in 500mg caplets. Patients will take 8 caplets per day (total dose: 4 grams per day) for 52 weeks.

Group II: Placebo Placebo Group 1 Intervention

The oral placebo (sugar pill) will be distributed in 500mg caplets. Patients will take 8 caplets per day for 52 weeks.
