Conditions

Cognitive Impairment, Schizophrenia

Brief summary

This is a Phase 2, double-blind, placebo-controlled, two-way crossover study to compare the efficacy of ALTO-101T versus placebo in change in electroencephalogram (EEG) cognitive processing markers and measures of cognition. Additional goals are to assess pharmacokinetic (PK), safety, and tolerability of the recently developed ALTO-101T transdermal delivery system (TDS) formulation in a patient population.
