Levetiracetam in Early Psychosis

October 26, 2022 updated by: NYU Langone Health

A Randomized, Double-blind, Placebo-controlled Trial Investigating the Effects of Levetiracetam in Early Psychosis

In order to establish target engagement and identify an effective dose the investigators will conduct a placebo-controlled single-dose parallel group trial of levetiracetam 185 mg and 500 mg in 24 medication-naïve early psychosis (EP) patients, measuring hippocampal activity by pulsed arterial spin labelling (ASL) pre-dose and 2 hours post-dose. The lower dose is calculated to achieve blood levels within the range that were associated with reduced hippocampal activity and improved cognition in patients with mild cognitive impairment; the higher dose is a typical antiepileptic dose. Successful demonstration of target engagement will be defined by an effect size of 0.5 or greater compared to placebo in reduction by levetiracetam of hippocampal blood flow measured by ASL. The optimal dose will be defined by maximal reduction of hippocampal perfusion in the absence of clinically-significant adverse effects. The investigators will also study 8 healthy control subjects to verify that baseline hippocampal blood flow is elevated in the sample of EP subjects.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study
