A Single-Center, Double-Blind, Placebo-Controlled, Randomized Blocks Study Investigating the Effect of 4 Dosages (1 mg, 5 mg, 15 mg, 50 mg) of MEM 3454 on P50 Sensory Gating and Mismatch Negativity (MMN) in Patients With Schizophrenia
The purpose of this study is to evaluate the effects of nicotinic alpha-7 MEM 3454 on P50
sensory gating in patients with Schizophrenia. The hypothesis is that MEM 3454 will
normalize the P50 ratio.
Data produced in this study will provide useful information regarding the value of P50 as an
efficacy biomarker, and provide evidence for the optimal dosing of MEM 3454 for additional
P50 studies.
