Effects of Armodafinil on Cognition for Patients With Schizophrenia or Schizoaffective Disorder

July 21, 2025 updated by: Northwestern University

Effect of Addition of Modafinil on the Tolerability and Efficacy for Cognition of Atypical Antipsychotic Drugs in Patients With Schizophrenia or Schizoaffective Disorder

This is a six week, double blind,placebo controlled study for patients with schizophrenia or schizoaffective disorder treated with an atypical antipsychotic for at least two months. Subjects will be randomized to take armodafinil (Nuvigil) or placebo along with their current antipsychotic and tested at baseline and week 6 for differences in memory, attention and problem-solving ability. Changes in weight during the six week study will also be tracked.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Armodafinil (Nuvigil)
First group will be randomized to take Armodafinil (Nuvigil) 150 mg, along with their current anti psychotic medication and tested at baseline and week 6 for differences in memory, attention and problem-solving ability. Changes in weight during the six week study will also be tracked.
Drug: armodafinil (Nuvigil)
armodafinil (Nuvigil)150 mg qd
Placebo Comparator: Placebo
Second group will be randomized to take placebo,identical in appearance to active comparator, along with their current anti psychotic medication and tested at baseline and week 6 for differences in memory, attention and problem-solving ability. Changes in weight during the six week study will also be tracked.
Drug: placebo

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Cognition Measured by AX-Continuous Performance Test (AX-CPT) D-prime Score
Time Frame: Baseline and week 6
For the AX-CPT, subjects are required to maintain an attentional set across a delay interval in order to overcome a prepotent response tendency (target responses are required when an X is presented but only in the context of a preceding A; non-target conditions are AY, BX and BY). The dependent measure was d-prime at the long delay (calculated as AX hits minus BX false alarms, which is particularly sensitive to context processing impairments in individuals with schizophrenia.
Baseline and week 6
