Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The present study is a proof-of-concept clinical trial to test the efficacy of low doses of a repurposed anti-epileptic drug (levetiracetam) in treating memory problems in Parkinson's disease (PD). Neuroimaging techniques will be used to determine the effect of the drug on specific brain regions (hippocampal subfields). Finally, baseline brain activity of PD patients with memory problems will be compared to PD patients without memory problems and healthy older adults to determine if activity in specific brain regions (hippocampal subfields) can be used to predict memory problems in PD. This information will be useful for future clinical trials to target drugs to these brain regions.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Active arm

125mg Levetiracetam capsules taken twice daily (morning and evening) for 14 days

Group Type EXPERIMENTAL

Levetiracetam

Intervention Type DRUG

Levetiracetam is currently approved in Australia and the U.S.A. for epilepsy. We will be providing levetiracetam in capsule form, 125mg levetiracetam in each capsule.

Placebo arm

125mg maize starch-based placebo capsules taken twice daily (morning and evening) for 14 days

Group Type PLACEBO_COMPARATOR

Placebo

Intervention Type DRUG

Placebo intervention will be maize-starch filled capsules with identical physical features to the active capsules.
